A national healthadvisory issued by U.S. Surgeon General Vivek Murthy on May 3, 2023, sheds light on the urgent public health issues of loneliness and isolation.
The report reflects Dr. Murthy’s personal and professional experience with the damaging health impacts of loneliness. As surprising as it sounds, social isolation and loneliness have the same effect on human health as smoking 15 cigarettes a day, which is to say, it can shorten life span by up to 15 years.
In the same survey, young adults were nearly twice as likely as those over age 65 to report feeling lonely or isolated. In addition, 75% of Hispanics and 68% of Black or African American people reported these conditions, as did a majority of lower-income respondents and single parents.
While there are no definitive explanations for these high numbers, experts have suggested several possible determinants: the mobility of the population, the shift from in-person to remote work and learning since the beginning of the pandemic, and the deep divides in society caused by social media and irresponsible news sites. To grab the attention of viewers, some advertisers and media leaders understand that human beings are biased toward messages that activate fear and loss. In fact, the scientific term “aversion bias” demonstrates people are twice as fearful of loss as happy for gain.
When we feel socially isolated and lonely, our vigilance for threat activates our core survival instincts, which are rooted in evolutionary times. For early humans, being accepted and belonging to a group or community were key factors in survival. Being separated or ousted from one’s tribe meant almost certain death.
Thriving relationships became critical to human feelings of safety and well-being. In fact, longevity studies consistently find that the strength of one’s lifelong relationships is the most important driver of a long and healthy life.
Stress and loneliness are connected
The human nervous system is balanced into two modes: the “fight or flight” of the sympathetic system and the “rest and digest” of the parasympathetic system.
Loneliness and isolation drive unbalanced activation of the sympathetic nervous system, leading to hypervigilance, or scanning the environment for threats. Once this threat response is activated, people see their environment as unsafe, leading to release of hormones that interfere with our trust and pleasure responses. As this stress-response heightens, people experience surges in hormones that elevate their heart rate and blood pressure.
Over time, release of these hormones damages our blood vessels, heart, brain, blood and liver and our metabolic and musculoskeletal systems. Much like a car engine that is continually over-revved, our body’s systems begin to break down and our perceived experience of pain is heightened.
Feelings of worthlessness and fear increase the risk of substance use, mental health challenges, a variety of chronic diseases and obesity – all of which can contribute to a reduced life span.
In other words, loneliness and isolation drive disease and shorten life spans through unbalanced activation of the sympathetic nervous system induced by the perception of threat and chronic stress.
Princeton University economists Anne Case and Angus Deaton hypothesize that the reduction of social capital and hope stemming from the loss of jobs in Appalachia and the Ohio River Valley from 1999 to 2013 was a key driver of deaths from overdose, suicide and liver disease in these areas.
So what can be done to address the loneliness epidemic?
In his Framework for a National Strategy to Advance Social Connection, Murthy provides a practical call for action to address the public health problem of social disconnection and to strengthen social connection and community. These strategies include being open to new relationships, reconnecting with friends and distant family members and serving others by volunteering. The framework includes shareable tools and resources for individuals and organizations to invest in community-based social relationships and improve their community’s mental health.
One reason I am answering this call is that my home state of West Virginia is the only one located entirely in Appalachia.
Appalachia is the central location of “deaths of despair,” meaning people living here are disproportionately affected by the loss of jobs, social capital, purpose and relationships that result in the experience of loneliness and social isolation.
But I would argue West Virginia also has resilient people who care about one another. There is a real goodness and kindness in our people. To serve our state better, the staff at the flagship university academic medical center is building more sophisticated and better health care access. My colleagues in business and government are focusing on reversing loneliness and social isolation through jobs that provide income, social capital and caring relationships.
Like the COVID-19 pandemic, the isolation and loneliness pandemic requires us to work together in community to make a positive difference.
LAKE COUNTY, Calif. — Lake County Economic Development Corp. has received $80,000 in Economic Development Administration funding to complete an update to the Comprehensive Economic Development Strategy, or CEDS.
To complete the project, the county of Lake, and cities of Lakeport and Clearlake have contributed a total of $20,000 in matching funds.
The CEDS update is a locally driven effort to guide the economic prosperity and resiliency and serves to engage community leaders, private sector firms and industries in the development of the five-year plan.
The completed CEDS will act as a road map for future economic development efforts and provide supporting documents when seeking federal grant funding to complete projects that fit within priorities named within the CEDS.
Lake EDC will be seeking community input and collaboration during the 12-month process.
Steps in the process will include data analysis, community listening sessions and engagement with agencies involved in infrastructure, private sector industry, healthcare, resiliency, education, natural environment, and government.
Additionally, Lake EDC will be publishing a request for proposals, or RFPs, to assist in the development of the CEDS.
To find out more about the CEDS process, how you can participate, or how to bid on the RFPs, visit https://lakecountycaedc.org/CEDS/.
NORTH COAST, Calif. — Lightning may have sparked a fire that began on Sunday night in Colusa County.
The Lodoga fire was first reported at around 9:45 p.m. Sunday south of East Park Reservoir in Colusa County, off Leesville Lodoga Road and Cook Springs Road.
The fire was reported on a ridge in an area where lightning strikes had occurred shortly beforehand as the result of a brief lightning storm that had passed through the region.
Initial estimates of the fire’s size put it at about three acres.
Cal Fire reported overnight that the fire is in a remote area and burning in grass and oak woodland. Firefighters were challenged in their attempts to find better access to it.
Copter 102 flew the incident after midnight and estimated the fire was between 20 and 25 acres. Radio reports said they hoped to hold it at that size.
At that point the fire resources at the scene were making their way to the fire’s perimeter, Cal Fire said, with more engines requested to respond.

Weather forecasts have gotten quite good over the years, but their temperatures aren’t always spot on – and the result when they underplay extremes can be lethal. Even a 1-degree difference in a forecast’s accuracy can be the difference between life and death, our research shows.
We found that when the forecasts underplayed the risk, even small forecast errors led to more deaths.
Our results also show that improving forecasts pays off. They suggest that making forecasts 50% more accurate would save 2,200 lives per year across the country and would have a net value that’s nearly twice the annual budget of the National Weather Service.
Forecasts that are too mild lead to more deaths
In the U.S. alone, the National Oceanic and Atmospheric Administration issues 1.5 million forecasts per year and collects around 76 billion weather observations that help it and private companies make better forecasts.
We examined data on every day’s deaths, weather and National Weather Service forecast in every U.S county from 2005 to 2017 to analyze the impact of those forecasts on human survival.
We then compared deaths in each county over the week following a day with accurate forecasts to deaths in the same county over the week following a day with inaccurate forecasts but the same weather. Because weather conditions were the same, any differences in mortality could be attributed to how people’s reactions to forecasts affected their chance of dying in that weather.
We found similar results when the forecast was wrong on hot days with temperatures above 86 degrees Fahrenheit (30 Celsius) and on cold days with temperatures below freezing. Both summer days that were hotter than forecast and winter days that were colder had more deaths. Forecasts that went the other way and overestimated the summer heat or winter cold had little impact.
That doesn’t mean forecasters should exaggerate their forecasts, however. If people find that their forecasts are consistently off by a degree or two, they might change how they use forecasts or come to trust them less, leaving people at even higher risk.
People are paying attention
People do pay attention to forecasts and adjust their activities.
The American Time Use Survey, conducted continuously for the U.S. Bureau of Labor Statistics, shows what Americans across the country are doing on any given day. We found that on days when the forecast called for temperatures to be milder than they turned out to be – either cooler on a hot day or warmer on a cold day – people in the survey spent more time on leisure and less in home or work settings.
Electricity use also varies in sync with forecasts, suggesting that people’s use of air conditioning does not just respond to the weather outside but also depends on how they planned for the weather outside.
However, forecasts are not used equally across society. Deaths among racial minorities are less sensitive to forecast errors, we found. That could be due in part to having less flexibility to act on forecasts, or not having access to forecasts. We will dig into this difference in future work, as the answer determines how the National Weather Service can best reach everyone.
The value of better forecasts
It’s clear that people use forecasts to make decisions that can matter for life and death – when to go hiking, for example, or whether to encourage an elderly neighbor to go to a cooling center.
So, what is the value of accurate forecasts?
We combined our theoretical model with federal cost-benefit estimates of how people value improvements in their chances of survival. From those, we estimated people’s willingness to pay for better forecasts. That calculation accounts for the risk of dying from extreme weather and for the costs of using forecasts to reduce their risk of dying, such as the costs of altering work and play schedules or using electricity.
Weather forecasts have gotten steadily better over the past decades. About 68% of the next-day temperature forecasts now have an error of less than 1.8 degrees. Our results suggest investing in improved forecast accuracy would probably be worth the cost.
Past improvements have come from better models, better observations and better computers. Future improvements could come from similar channels or from applying recent innovations in machine learning and artificial intelligence to weather prediction and communication.
I am an avid fisherman and moved to Lake County to enjoy my retirement fishing on Clear Lake. I recently purchased a bass boat and had to purchase a Lake County quagga mussel sticker. I don’t know much about these mussels or what would happen if they got into our lake. Can you provide some information so I can make sure we are doing all we can to protect Clear Lake?
Thanks,
Frank the fisherman
Dear Fisherman Frank,
Thanks for this very important and timely question. This is a question I get asked about quite frequently, and I am glad to be able to “dive” into this topic in breadth. Since this topic is so important, I will be writing about it in two columns.
In part 1, we will discuss the origins of invasive mussels, how they came to the United States and what it would mean for Clear Lake should an invasive mussels become introduced or established in the Lake, or any Lake County water bodies.
In my next column, part 2, I will describe our prevention program and how it works and how we can all help keep invasive mussels out of Clear Lake. Lastly, we will talk about what would happen if we got an introduction into Clear Lake, and the County of Lake’s current plans for a rapid response, control, eradication and containment plan. There is even a way for the public — you! — to be involved in the planning process.
Before we go further, let’s be clear about what defines an invasive species. According to the US EPA Watershed Academy, an invasive species is defined as “ A species that is not native in origin, whose presence in the environment causes economic or environmental harm or harm to human health.”
A non-native species that becomes introduced, or brought into a new environment, but does not successfully reproduce and become prolific is not considered an invasive species.
A non-native species that is introduced into a new environment, and successfully reproduces, and those offspring reproduce, is also not considered an invasive species. For this last one think about the Florida Black Bass in Clear Lake, who are successfully established and whose presence is a benefit to the local economy.
For a species to be really considered invasive, they must be introduced into a new environment, successfully reproduce, thrive, and cause some damage to native species, the environment in general, cause economic negative impacts, or cause human or public health impacts.
We will discuss how invasive mussels will impact the environment, or ecology, of Clear Lake, and the local economy. Invasive mussels can indirectly impact human health.
As an example, an invasive species that facilitates public health or human harm can include the invasive creeping water primrose that stagnates channels and coves and creates habitat havens for West Nile mosquitoes. Invasive species that directly cause human harm are perfectly exemplified in the several invasive mosquitos that carry and transmit diseases such as the Asian tiger mosquito (Aedes albopictus) that can transmit West Nile and Dengue fever.
In this case, invasive mussels as demonstrated in other aquatic systems, where they have been introduced and established, have caused impacts on all three facets of the US EPA definition.
Where invasive mussels are native
Invasive mussels, or specifically Quagga (Dreissena rostriformis bugensis) and Zebra (Dreissena polymorpha) mussels, are freshwater mussels in the Dreissenidae family. I will refer to these mussels as invasive dreissenid mussels. They are relatively small mussels and at a maximum cna grow up to 2 inches. They are shaped like a “D”, with a straight edge and striped shells, with black, gray, brown and white patterns — hence the reference to zebra common name.
Dreissenid mussels are native to lakes and tributaries in the region around southern Russia, Ukraine, Georgia, Romania, and Uzbekistan in water bodies such as the Black Sea, Sea of Azov, Caspian Sea, and Aral Sea. While there are fish and diving ducks native to the eastern european region where Dreissenid mussels are from, there are not the same predators in North American waters where these mussels have been introduced. Some natural predators of dreissenid mussels have also been introduced to North America, but they don’t prey upon the mussels like they do in their native habitat.
The round goby fish is an example, as it’s a species native to the eastern european waters alongside dreissenid mussels, where they are a main food source. Round gobies have been introduced into the Great Lakes, yet they are a food source for many native and invasive species, which keeps their abundance regulated. Round gobies have also been shown to prefer to forage on native north american mussels compared to their homeland’s Dreissenids.
How invasive mussels got to the United States
Invasive dreissenid mussels were introduced into North America through transatlantic freighter ships that started their voyage in the Black Sea and traveled across the Atlantic and through the St. Lawrence Seaway channel and lock system between US and Canada and into the Great Lakes.
From the Black Sea, freighter ships would drop off and pick up goods while also picking up water in their ballast tanks. Large ships use ballast tanks, which are large holding tanks with pumps, to balance loads and distribute weight evenly across the vessel, to ensure stability and safety when the ship is traveling and when they are loading or unloading cargo.
Ships leaving the Black Sea would travel through the Turkish Straits, a system of international water passages that connects the Black Sea ultimately to the Mediterranean Sea and then the Atlantic.
Once the ships had crossed the Atlantic, to gain access to large, safe ports of Canada such as Quebec City, Toronto, Hamilton, and Thunder Bay and US ports such as Toledo, Chicago, Duluth-Superior, Thunder Bay, they would have to enter the St. Lawrence River and into the man-made channel and lock system of the Great Lakes St. Lawrence Seaway.
The system of Canadian and US locks, canals, and channels has several locations where ships have to raise and lower to be level with the seaway, and at each of these junctions, they can release and take on water in their ballasts, to balance their load and adjust the weight of their ship. Likewise, any stops at ports along the Seaway, or within any of the Great Lakes, would require a release and intake of ballast water, to adjust as loads are changed.
During all this movement of water coming and going from a ship’s ballast tanks, there is ample opportunity for aquatic invasive species, that have been picked up in the ballast water from the ships point of origin — or anywhere else along their route — to be released into the “new environment” during a ballast adjustment.
Normally, and obviously, freshwater species and saltwater species don’t occur in the same habitat, so one way for freighter ships to prevent the spread of invasives along transatlantic routes is to implement ballast water management. The requirements are designed by the International Maritime Organization or IMO. The US governmental arm that participates in the IMO is the Shipping Coordinating Committee which is part of the Office of Ocean and Polar Affairs within the State Department.
Besides invasive dreissenid mussels, proper ballast water management programs have been successful in preventing the spread of other threatening and dangerous invasive species such as Asian Kelp, cholera, European green crab, and North Pacific seastar. Each of these species, in areas where they have been introduced and established, have caused significant economic and ecological harm, and in the case of cholera, significant human harm.
Invasive dreissenid mussels, once introduced into the Great Lakes, found suitable habitat in the freshwaters that were similar in latitude and habitat to their native waters. Once established in an area, they proliferated throughout the entire watershed, downstream throughout the Mississippi Basin, the Ohio River, and throughout the midwest, eastern seaboard, and into the Southern United States.
While it’s unknown when the first introductions took place, the first detections of mussels occurred in New York in the 1980s. By the 1990s mussels had been found west of the Rockies and the first detection in California occurred in 2007 in several border counties in southern California.
Invasive dreissenid mussels spread throughout non-connected water bodies on trailered boats overland. While adult mussels are sessile and attach to substrates and structures in water bodies, the juveniles, called veligers, are free floating in the water column and can survive in very small amounts of water that doesn’t get above 120 degrees F. Any boat or watercraft that has a compartment or space that holds water, could potentially be moving veliger - mussel - infested water over land.
Once a veliger, or adult mussel is introduced to a new water body, and the local water conditions are suitable, they can easily reproduce and a population is therefore established.
A single mussel can produce a million gametes sometimes up to six times a year. When fertilization occurs in the water column, the fertilized zygote turns into the larvae stage of a juvenile mussel, called a veliger. While the individual number of veligers that survive is low, the abundance of gamete production ensures high reproductive rates and lakes that were previously uninfested, quickly transform once the mussels spread.
Impacts of invasive mussels
Invasive Quagga and Zebra mussels, if introduced into Clear Lake, would cause significant negative impacts. These impacts can be divided into ecological, economical, and public health. And some impacts overlap more than one category.
For example, invasive dreissenid mussels are filter feeders, removing green algae from the water column, sometimes up to 3 liters a day. Green algae is the base of the food web in fish-dominated lakes like Clear Lake. Drastic changes to the food web will impact the current lake ecology and the local economy that depends on current lake ecology - like the presence of large and abundant game fish like catfish, black bass, and crappie.
Green algae are consumed by zooplankton (small aquatic insects or copepods) which is the main food source for small bait fish, like minnows, shad and sunfish. Larger game fish can consume both bait fish and zooplankton. Almost all small, juvenile fish feed off both green algae and zooplankton. If Invasive dreissenid mussels were introduced into Clear Lake, they would significantly disrupt the base of the food web, with high probability of causing a fishery decline or crash.
This effect has been identified in other aquatic ecosystems with most impacts occurring to recreationally and commercially important species. For example, in Lake Ontario, following Zebra mussel introduction, Lake Whitefish and Walleye populations declined and recruitment reduced as the mussels compete directly with preferred fish food.
Some local myths exist that suggest that mussels would “clear up the water” and “take care of our harmful algae problem” in Clear Lake. Unfortunately, lab and field studies have demonstrated that this would not be true. Laboratory studies have shown that dreissenid mussels selectively eat green algae (phytoplankton) as opposed to cyanobacteria (which is the category of organism responsible for creating harmful algal blooms in Clear Lake).
Specifically, the dreissenid mussels will spit out the cyanobacteria, and only metabolize the green algae. And since cyanobacteria are not fish food, we will see declines in food available for fisheries, and more space and resources available for cyanobacteria as the valuable green algae declines.
One just has to look to Toledo, Ohio, located on Lake Erie, which has an abundance of invasive dreissenid mussel populations and worsening annual cyanobacteria blooms, to understand that the presence of invasive dreissenid mussels does not benefit water quality.
Invasive dreissenid mussels can have direct impacts to the economy through their disruption to drinking water systems. Clear Lake provides drinking water to about 60% of the Lake County population via 17 private and public drinking water purveyor systems. Intakes located within the lake could suck in juvenile mussels, or veligers.
Once inside the drinking water intake infrastructure, the dreissenid mussels could settle and attach and eventually accumulate within the pipes reducing the available space for water volume. Additionally, the dreissenid mussels produce waste and as they die, the bacteria can contaminate the water headed to treatment, creating complications for treatment systems. This is where invasive dreissenid mussels could heavily harm human health and could cause public health concerns.
As dreissenid mussels in drinking water pipes die, they decompose and the bacteria, smells, and particulates within the systems would lead to cost increases to produce safe drinking water. And if the water couldn’t be treated adequately, the system would have to be purged, wasting millions of gallons of Clear Lake water. The time, staff, tools, and effort needed to remove the mussels from the infrastructure within the lake would also be expensive.
All these costs would be passed down to the consumers, or residents of Lake County. I would further suggest that the costs associated with mitigating invasive dreissenid mussels in drinking water would bankrupt some of the smaller water treatment systems, as water rates from Clear Lake are already the 3rd highest rate in the state.
Additionally, invasive dreissenid mussels can cause economic impacts by their contribution to the decrease in recreational value in freshwater lakes. Dreissenid mussels grow exponentially and when they die, their sharp shells can accumulate on beaches and shorelines causing difficulty for people and animals to safely access the water.
Some beaches in Michigan, and other states, that have miles of dunes composed of sharp, dead mussel shells, are basically abandoned, and can’t serve any recreational purpose. Businesses that rely on that water access struggle to survive and stay afloat.
Adult mussels can also settle and attach to any structure in the water, including ramps, docks, anchor lines, and boat hulls and propellers. Imagine having to laboriously scrape your boat hull of mussels twice a year, or not being able to launch your kayak on your ramp because it’s covered in sharp mussels.
This is the reality of people with lakeside properties that live on mussel-infested lakes and could be the fate of Clear Lake shoreline residents should mussels become established in our lake.
To be continued…
I hope you learned a little bit about invasive dreissenid mussels, Fisherman Frank. I hope you read my next column, where I will focus on our Invasive Mussel Prevention Plan and Program, including how the stickers work to prevent mussels in our lake and how the ramp monitors are key in the prevention program.
Also in my next column, I will discuss what is being planned at the County of Lake Water Resources Department, should an invasive mussel make it to Clear Lake and a population establish. The goal is to maintain Clear Lake ecology so that we can maintain our way of life, and prevent the spread to other northern California lakes.

From our cosmic backyard in the solar system to distant galaxies near the dawn of time, NASA’s James Webb Space Telescope has delivered on its promise of revealing the universe like never before in its first year of science operations.
To celebrate the completion of a successful first year, NASA has released Webb’s image of a small star-forming region in the Rho Ophiuchi cloud complex.
“In just one year, the James Webb Space Telescope has transformed humanity’s view of the cosmos, peering into dust clouds and seeing light from faraway corners of the universe for the very first time. Every new image is a new discovery, empowering scientists around the globe to ask and answer questions they once could never dream of,” said NASA Administrator Bill Nelson. “Webb is an investment in American innovation but also a scientific feat made possible with NASA’s international partners that share a can-do spirit to push the boundaries of what is known to be possible. Thousands of engineers, scientists, and leaders poured their life’s passion into this mission, and their efforts will continue to improve our understanding of the origins of the universe — and our place in it.”
The new Webb image released today features the nearest star-forming region to us. Its proximity at 390 light-years allows for a highly detailed close-up, with no foreground stars in the intervening space.
“On its first anniversary, the James Webb Space Telescope has already delivered upon its promise to unfold the universe, gifting humanity with a breathtaking treasure trove of images and science that will last for decades,” said Nicola Fox, associate administrator of NASA’s Science Mission Directorate in Washington. “An engineering marvel built by the world’s leading scientists and engineers, Webb has given us a more intricate understanding of galaxies, stars, and the atmospheres of planets outside of our solar system than ever before, laying the groundwork for NASA to lead the world in a new era of scientific discovery and the search for habitable worlds.”
Webb’s image shows a region containing approximately 50 young stars, all of them similar in mass to the Sun, or smaller.
The darkest areas are the densest, where thick dust cocoons still-forming protostars. Huge bipolar jets of molecular hydrogen, represented in red, dominate the image, appearing horizontally across the upper third and vertically on the right. These occur when a star first bursts through its natal envelope of cosmic dust, shooting out a pair of opposing jets into space like a newborn first stretching her arms out into the world.
In contrast, the star S1 has carved out a glowing cave of dust in the lower half of the image. It is the only star in the image that is significantly more massive than the Sun.
“Webb’s image of Rho Ophiuchi allows us to witness a very brief period in the stellar life cycle with new clarity. Our own Sun experienced a phase like this, long ago, and now we have the technology to see the beginning of another’s star’s story,” said Klaus Pontoppidan, who served as Webb project scientist at the Space Telescope Science Institute in Baltimore, Maryland, since before the telescope’s launch and through the first year of operations.
Some stars in the image display telltale shadows indicating protoplanetary disks — potential future planetary systems in the making.
A full year, across the full sky
From its very first deep field image, unveiled by President Joe Biden, Vice President Kamala Harris and Nelson live at the White House, Webb has delivered on its promise to show us more of the universe than ever before. However, Webb revealed much more than distant galaxies in the early universe.
“The breadth of science Webb is capable of exploring really becomes clear now, when we have a full year’s worth of data from targets across the sky,” said Eric Smith, associate director for research in the Astrophysics Division at NASA Headquarters and Webb program scientist. “Webb’s first year of science has not only taught us new things about our universe, but it has revealed the capabilities of the telescope to be greater than our expectations, meaning future discoveries will be even more amazing.” The global astronomy community has spent the past year excitedly poring over Webb’s initial public data and getting a feel for how to work with it.
Beyond the stunning infrared images, what really has scientists excited are Webb’s crisp spectra — the detailed information that can be gleaned from light by the telescope’s spectroscopic instruments. Webb’s spectra have confirmed the distances of some of the farthest galaxies ever observed, and have discovered the earliest, most distant supermassive black holes.
They have identified the compositions of planet atmospheres (or lack thereof) with more detail than ever before, and have narrowed down what kinds of atmospheres may exist on rocky exoplanets for the first time.
They also have revealed the chemical makeup of stellar nurseries and protoplanetary disks, detecting water, organic carbon-containing molecules, and more. Already, Webb observations have resulted in hundreds of scientific papers answering long-standing questions and raising new ones to address with Webb.
The breadth of Webb science is also apparent in its observations of the region of space we are most familiar with — our own solar system.
Faint rings of gas giants appear out of the darkness, dotted by moons, while in the background Webb shows distant galaxies.
By comparing detections of water and other molecules in our solar system with those found in the disks of other, much younger planetary systems, Webb is helping to build up clues about our own origins — how Earth became the ideal place for life as we know it.
“With a year of science under our belts, we know exactly how powerful this telescope is, and have delivered a year of spectacular data and discoveries,” said Webb Senior Project Scientist Jane Rigby of NASA's Goddard Space Flight Center. “We've selected an ambitious set of observations for year two — that builds on everything we've learned so far. Webb's science mission is just getting started — there's so much more to come.”
The James Webb Space Telescope is the world's premier space science observatory. Webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, European Space Agency and the Canadian Space Agency.
I am an astronomer who studies astrobiology and planets around distant stars. For the last seven years, I have been co-leading a team that is developing a new kind of space telescope that could collect a hundred times more light than the James Webb Space Telescope, the biggest space telescope ever built.
Almost all space telescopes, including Hubble and Webb, collect light using mirrors. Our proposed telescope, the Nautilus Space Observatory, would replace large, heavy mirrors with a novel, thin lens that is much lighter, cheaper and easier to produce than mirrored telescopes. Because of these differences, it would be possible to launch many individual units into orbit and create a powerful network of telescopes.
The need for larger telescopes
Exoplanets – planets that orbit stars other than the Sun – are prime targets in the search for life. Astronomers need to use giant space telescopes that collect huge amounts of light to study these faint and faraway objects.
Existing telescopes can detect exoplanets as small as Earth. However, it takes a lot more sensitivity to begin to learn about the chemical composition of these planets. Even Webb is just barely powerful enough to search certain exoplanets for clues of life – namely gases in the atmosphere.
The James Webb Space Telescope cost more than US$8 billion and took over 20 years to build. The next flagship telescope is not expected to fly before 2045 and is estimated to cost $11 billion. These ambitious telescope projects are always expensive, laborious and produce a single powerful – but very specialized – observatory.
A new kind of telescope
In 2016, aerospace giant Northrop Grumman invited me and 14 other professors and NASA scientists – all experts on exoplanets and the search for extraterrestrial life – to Los Angeles to answer one question: What will exoplanet space telescopes look like in 50 years?
In our discussions, we realized that a major bottleneck preventing the construction of more powerful telescopes is the challenge of making larger mirrors and getting them into orbit. To bypass this bottleneck, a few of us came up with the idea of revisiting an old technology called diffractive lenses.
Conventional lenses use refraction to focus light. Refraction is when light changes direction as it passes from one medium to another – it is the reason light bends when it enters water. In contrast, diffraction is when light bends around corners and obstacles. A cleverly arranged pattern of steps and angles on a glass surface can form a diffractive lens.
The first such lenses were invented by the French scientist Augustin-Jean Fresnel in 1819 to provide lightweight lenses for lighthouses. Today, similar diffractive lenses can be found in many small-sized consumer optics – from camera lenses to virtual reality headsets.
Thin, simple diffractive lenses are notorious for their blurry images, so they have never been used in astronomical observatories. But if you could improve their clarity, using diffractive lenses instead of mirrors or refractive lenses would allow a space telescope to be much cheaper, lighter and larger.
A thin, high-resolution lens
After the meeting, I returned to the University of Arizona and decided to explore whether modern technology could produce diffractive lenses with better image quality. Lucky for me, Thomas Milster – one of the world’s leading experts on diffractive lens design – works in the building next to mine. We formed a team and got to work.
Over the following two years, our team invented a new type of diffractive lens that required new manufacturing technologies to etch a complex pattern of tiny grooves onto a piece of clear glass or plastic. The specific pattern and shape of the cuts focuses incoming light to a single point behind the lens. The new design produces a near-perfect quality image, far better than previous diffractive lenses.
Because it is the surface texture of the lens that does the focusing, not the thickness, you can easily make the lens bigger while keeping it very thin and lightweight. Bigger lenses collect more light, and low weight means cheaper launches to orbit – both great traits for a space telescope.
In August 2018, our team produced the first prototype, a 2-inch (5-centimeter) diameter lens. Over the next five years, we further improved the image quality and increased the size. We are now completing a 10-inch (24-cm) diameter lens that will be more than 10 times lighter than a conventional refractive lens would be.
Power of a diffraction space telescope
This new lens design makes it possible to rethink how a space telescope might be built. In 2019, our team published a concept called the Nautilus Space Observatory.
Using the new technology, our team thinks it is possible to build a 29.5-foot (8.5-meter) diameter lens that would be only about 0.2 inches (0.5 cm) thick. The lens and support structure of our new telescope could weigh around 1,100 pounds (500 kilograms). This is more than three times lighter than a Webb–style mirror of a similar size and would be bigger than Webb’s 21-foot (6.5-meter) diameter mirror.
The lenses have other benefits, too. First, they are much easier and quickerto fabricate than mirrors and can be made en masse. Second, lens-based telescopes work well even when not aligned perfectly, making these telescopes easier to assemble and fly in space than mirror-based telescopes, which require extremely precise alignment.
Finally, since a single Nautilus unit would be light and relatively cheap to produce, it would be possible to put dozens of them into orbit. Our current design is in fact not a single telescope, but a constellation of 35 individual telescope units.
Each individual telescope would be an independent, highly sensitive observatory able to collect more light than Webb. But the real power of Nautilus would come from turning all the individual telescopes toward a single target.
By combining data from all the units, Nautilus’ light-collecting power would equal a telescope nearly 10 times larger than Webb. With this powerful telescope, astronomers could search hundreds of exoplanets for atmospheric gases that may indicate extraterrestrial life.
Although the Nautilus Space Observatory is still a long way from launch, our team has made a lot of progress. We have shown that all aspects of the technology work in small-scale prototypes and are now focusing on building a 3.3-foot (1-meter) diameter lens. Our next steps are to send a small version of the telescope to the edge of space on a high-altitude balloon.
With that, we will be ready to propose a revolutionary new space telescope to NASA and, hopefully, be on the way to exploring hundreds of worlds for signatures of life.
CLEARLAKE, Calif. — A COVID-19 outbreak at Hope Center led to a temporary hold on admissions earlier this month.
Hope Center is a 20-bed transitional housing facility owned and housing navigation hub located at 3400 Emerson St. in Clearlake.
It’s operated by Adventist Health Clear Lake and staffed by Adventist Health associates around the clock, seven days a week.
On Wednesday, July 5, six participants and one associate at Hope Center tested positive for COVID-19, said Luke McMurray, director of marketing and communications for Adventist Health.
“Each experienced mild flu-like symptoms. An RN [registered nurse] on staff assessed everyone. No one required further treatment,” McMurray said.
“To ensure safety, protocols developed by the Lake County Department of Health and Adventist Health Clear Lake Hospital Infection Control were strictly followed. Hope Center remained open, and new participants were not admitted,” he said.
As of Saturday, July 15, there were no new cases, all participants and associates are testing negative and Hope Center is accepting new participants, McMurray said.
McMurray said Adventist Health Clear Lake and Hope Center continue to keep safety their top priority.
LAKE COUNTY, Calif. — After losing one of its members in the spring, the Lake County Board of Education has appointed a well-known businesswoman to fill the vacancy.
At its meeting on Wednesday, June 14, the board voted to appoint Itzia Rico to be the trustee representing Area 5, which includes Kelseyville.
The vacancy occurred on April 27, due to the death of Board Member Anna Rose Ravenwoode.
The Lake County Office of Education held a public recruitment for board candidates and received three applications. Applicants were Rico, Shauna Petker and Gary Olson.
During a regular board meeting, board members Denise Loustalot, Melissa Kinsel, Mark Cooper and Nancy Hudson interviewed the three applicants in open session.
Following the board’s deliberation, the trustees voted to appoint Rico, who was then sworn in. The term of her appointment will be until December 2024.
Rico is a longtime Lake County resident and the owner of Studebakers coffee shop located in downtown Kelseyville. She is part of the Kelseyville Business Association and has served as their secretary.
“I realize how important it is for our youth to succeed. They are the future of our communities,” Rico said. “Through my own children, I see how much teachers influence our kids. I hope to learn how I can help too, as a board member.”
Rico is a mother of five children, four of whom are enrolled in schools in the Kelseyville Unified School District.
She has volunteered in classrooms, coached youth basketball and held a free volleyball camp for middle school players that did not make the school team.
She is always looking for ways to support schools and Lake County students.
“Her ties to the community, perspective as a parent and her focus on putting students first is a welcome addition to the dynamic of the Board of Education,” said Lake County Superintendent of Schools Brock Falkenberg.
The Board of Education thanks all applicants for putting themselves up for consideration.
Pursuant to California Ed Code section 5091, the Lake County Board of Education trustees provisionally appointed Itzia Rico to fill the vacancy on June 14, 2023.
Unless a petition calling for a special election containing a sufficient number of signatures is filed with the Lake County Superintendent of Schools within 30 days of the provisional appointment, the appointment shall become an effective appointment.
NICE, Calif. — The Robinson Rancheria Band of Pomo Indians marked a milestone in its history as a sovereign nation on Thursday evening.
As his family, tribal members and local dignitaries looked on, Officer Kyle Wheeler became the first federally commissioned police officer in Robinson Rancheria's history to attend and successfully complete a police academy while representing the Robinson Rancheria Police Department.
His proud chief, Derrell Hochstein, called it a “historical evening.”
It’s not just historical for the tribe but for the community as a whole, as Robinson Rancheria is Lake County’s only tribal police department.
Probably the most heartfelt tribute of the evening came from Wheeler’s wife, Kaitlyn Carter, who called him “our wonderful man in blue.”
Together, Hochstein and Wheeler make up the tribal police department, with Hochstein recruiting to continue to build the agency’s sworn personnel.
Hochstein lauded the tribal leadership and members for supporting Wheeler’s training and education as part of elevating the department.
However, Wheeler’s achievement of reaching Special Law Enforcement Commission, or SLEC, status came in no small part due to Hochstein’s efforts.
Hochstein took over as the chief at the Robinson Rancheria Police Department in January of 2022.
He brought with him almost 20 years of law enforcement experience, including working with other tribes at Fort Independence in Inyo County and with the Lovelock Tribal Police in Nevada, as well as serving in policing in Kern County.
Dignitaries taking part in the Thursday evening ceremony and dinner included Tribal Chair Beniakem Cromwell and Secretary-Treasurer Irenia Quitiquit; Sheriff Rob Howe; District 1 Supervisor Moke Simon, who chairs the Middletown Rancheria of Pomo Indians; District 4 Supervisor Michael Green; Terre Logsdon, the county’s climate resiliency officer and tribal liaison; sheriff’s Lt. Corey Paulich; and sheriff’s public information officer Lauren Berlinn.
They were joined by Wheeler’s family, including his wife, their children, his parents, grandparents and mother-in-law.
Simon and Green presented a certificate from Congressman Mike Thompson, who was unable to attend, recognizing Wheeler’s achievement.
Simon said that, from the county perspective, the milestone was about collaboration and cooperation.
He said he’s always admired how Robinson Rancheria has handled its police force.
During his remarks, Simon said that the milestone was one that all tribal nations in Lake County can be proud of.
“It’s a good night to be here,” Simon said.
For tribes, having a police department isn’t just another administrative function, but a way of reflecting their sovereignty, explained Christopher Lorenz, special agent in charge for the Bureau of Indian Affairs’ District IX, based in Sacramento.
Lorenz oversees the 104 tribes located completely within the state of California. Altogether, there are 109 tribes with a presence in the state.
Of those, Lorenz said Robinson Rancheria is one of only 22 with a federal cross-deputization agreement for policing, which Chief Hochstein said was a six-month process to complete.
Lorenz underlined the importance of having a police department, adding that it says a lot about what Robinson Rancheria wants in the future.
It sets a good example for other tribes and encourages them to have departments of their own, Lorenz said.
“Partnership is really the key,” said Lorenz, adding that he sees tribe officers as “free” officers for the county in which they are located, as they can be available to assist other agencies.
Sheriff Howe said that in today’s society, making the decision to get into law enforcement is a difficult one, with the work being important but often thankless.
He thanked Wheeler for getting into the profession at a time when society needs him the most.
Howe emphasized three words to Wheeler: Honor, integrity and respect.
He said for Wheeler to honor himself, the tribe and his family, to live his life and do his job with integrity, which no one can take from \him; and to treat all with respect, remembering that some may not respect him in turn, and others may not deserve his respect.
If Wheeler did those things, Howe added, he would make a difference.
Wheeler’s family also spoke, including his parents, Kelly and Becky Willard, and grandmother, Arlene Willard, who expressed to him how proud they are of his achievements.
His wife said he’s dedicated his life to protecting people, and has run through fires to save people, protected children from predators and given first aid.
“This is what he was meant to do,” Carter said, adding that his family will be there to support him.
The highlight of the evening was when Cromwell led Wheeler through a code of ethics before Hochstein gave him his oath and Carter pinned on his new badge.
Wheeler, who started with the tribe’s casino security department, recounted how tribal members welcomed his questions, and shared with him their culture and language.
He said he started his new journey into policing on Jan. 18, and on April 1 started the academy in Artesia, New Mexico, where he spent long days but created deep bonds with other officers in training from tribes around the country.
“I came back home with a larger fire inside of me,” Wheeler said, adding that he wants to learn more about the Pomo tribe and that he’ll do his best every day.
Hochstein pledged to support Wheeler and give him everything he needs to succeed in the days ahead.
Hochstein said anyone interested in joining the Robinson Rancheria Police Department can call the agency’s duty phone number at 707-533-0011 for more information.
