Poorly Circulated Room Air Raises Potential Exposure to Contaminants by up to 6 Times

Having good room ventilation to dilute and disperse indoor air pollutants has long been recognized, and with the COVID-19 pandemic its importance has become all the more heightened. But new experiments by indoor air researchers at Lawrence Berkeley National Laboratory (Berkeley Lab) show that certain circumstances will result in poor mixing of room air, meaning airborne contaminants may not be effectively dispersed and removed by building level ventilation.

Shock, insecurity and endless war: How 9/11 changed America and the world

For tens of millions of Americans alive on Sept. 11, 2001, the images are indelible: Flames exploding from a tower of the World Trade Center against a brilliant blue sky. In the shock that followed those terror attacks, it was common to imagine that the world had changed forever. Just how, exactly, no one could know. Twenty years later, after so many other turns of history, the ragged withdrawal of U.S. troops from Afghanistan is a reminder of how the nation has struggled to answer the attacks.

A peek inside a flying bat’s brain uncovers clues to mammalian navigation

When driving up to a busy intersection, you probably pay more attention to where you will be in the near future than where you are at that moment. After all, knowing when you will arrive at the intersection — and whether you need to stop or slow down to avoid a collision with a passing car, pedestrian or cyclist — is usually much more important than knowing your current location. This ability to focus on where we will be in the near future — rather than where we are in the present — may be a key characteristic of the mammalian brain’s built-in navigation system, suggests a new study appearing online Thursday, July 8, in the journal Science.

Insect-sized robot navigates mazes with the agility of a cheetah

Many insects and spiders get their uncanny ability to scurry up walls and walk upside down on ceilings with the help of specialized sticky footpads that allow them to adhere to surfaces in places where no human would dare to go. Engineers at the University of California, Berkeley, have used the principle behind these some of these footpads, called electrostatic adhesion, to create an insect-scale robot that can swerve and pivot with the agility of a cheetah, giving it the ability to traverse complex terrain and quickly avoid unexpected obstacles.

Very big changes are coming very fast to the American workplace

Going to work used to be so simple. Across a span of decades, in organizations large and small, American white-collar workers by the millions would wake up in the morning and get to the office by 8 or 9. They would leave at 5 or 6, perhaps later if they were on deadline with an important project. It was like clockwork. Suddenly, however, that model seems outdated, if not archaic. In a series of interviews, Berkeley scholars who study work and management say that as the COVID-19 pandemic eases, American executives and office workers are emerging into a new and unfamiliar world that may have broad benefits for both.

Stickleback fish provide genetic road map for rapid evolution

What happens when you dump an ocean fish into a freshwater lake? That experiment has been performed naturally tens of thousands of times over millions of years as sea-faring threespine sticklebacks — which, like salmon, travel up rivers to spawn — have gotten stranded in lakes and had to evolve as permanent denizens of fresh water. Michael Bell, currently a research associate in the University of California Museum of Paleontology at UC Berkeley, stumbled across one such natural experiment in 1990 in Alaska, and ever since has been studying the physical changes these fish undergo as they evolve and the genetic basis for these changes.

How American racism is rooted in residential segregation

The disproportionate use of police brutality against people of color in America. Higher COVID-19 death rates of Black and Latinx people in the health care system. Lower percentages of homeownership and loans approved in Black communities. Society often labels these disparities as racism or prejudice against individuals with specific racial identities. But new research from UC Berkeley’s Othering and Belonging Institute shows that these inequities are symptoms of a much more racially systemic problem — residential segregation.

The filibuster: A tool for compromise, or a weapon against democracy?

While the insurrection posed an existential threat to American democracy, Berkeley political and legal scholars say the arcane workings of the filibuster pose a threat, too, because it increasingly is being used to block majority rule.

Prices are spiking for homes, cars and gas. Don’t be alarmed, economists say

The U.S. Department of Labor reported yesterday that the Consumer Price Index rose 5% in May, following a 4.2% jump in April. But at UC Berkeley, high-level economists are offering some calming advice: A measure of inflation is inevitable as the U.S. economy comes back online, but it will likely be modest. And it will almost certainly blow over as the economy stabilizes.

Are heavy metals toxic? Scientists find surprising clues in yeast

Lanthanides are rare-earth heavy metals with useful magnetic properties and a knack for emitting light. Researchers had long assumed that lanthanides’ toxicity risk was low and therefore safe to implement in a number of high-tech breakthroughs we now take for granted: from OLEDs (organic light-emitting displays) to medical MRIs and even hybrid vehicles. In recent years, however, some scientists have questioned lanthanides’ safety. Now, a team of researchers led by the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and UC Berkeley has compiled the most complete library yet of lanthanides and their potential toxicity – by exposing baker’s yeast, aka Saccharomyces cerevisiae, to lanthanide metals. Their findings were recently published in the journal Proceedings of the National Academy of Sciences.

How antibiotic-filled poop helps ‘bessbug’ beetles stay healthy

The lifestyle of the horned passalus beetle, commonly known as the bessbug or betsy beetle, might seem downright disgusting to the average human: Not only does this shiny black beetle eat its own poop, known as frass, but it uses its feces to line the walls of its living space and to help build protective chambers around its developing young. Gross as it may seem, a new study suggests that this beetle’s frass habits are actually part of a clever strategy for protecting the insect’s health — and could help inform human medicine, too.

Berkeley researchers demonstrate new technique for surface-sensitive second harmonic generation utilizing non-linear optics with a table-top laser

Interfaces and surfaces are of central importance to many open scientific questions. For example, in order to design more energy-efficient all solid-state batteries to fuel next-generation electric cars, we need to better understand the charge transfer processes through the battery’s individual layers. Also, devising solutions for climate change requires an enhanced knowledge of pollutant uptake at the air-liquid interface of clouds. Scientific questions like these, that address the nature of chemical interfaces and surfaces, are notoriously challenging to address because of the difficulty in studying systems with boundary specificity. An international effort led by UC Berkeley Assistant Professor of Chemistry Michael Zuerch has demonstrated a novel experimental method to address questions like these utilizing nonlinear optics as discussed in a recent article published today in Science Advances(link is external).

As global climate shifts, forests’ futures may be caught in the wind

Forests’ ability to survive and adapt to the disruptions wrought by climate change may depend, in part, on the eddies and swirls of global wind currents, suggests a new study by researchers at the University of California, Berkeley. The findings are the first to show that wind may not only influence the spread of an individual tree or species’ genes, but can also help shape genetic diversity and direct the flow of gene variants across entire forests and landscapes.

Are renters — and the U.S. economy — hurtling toward an ‘eviction cliff’?

Schools and businesses are reopening, diners are returning to restaurants, and fans are returning to sports stadiums, but a new crisis in the COVID-19 pandemic may be just weeks away: the possible eviction of millions of Americans who have fallen behind in their rent. When massive job losses and other pandemic-driven economic pressures left many renters unable to pay and accumulating debt to their landlords, the federal government and some states set moratoria that blocked evictions. Now the U.S. ban is set to expire on June 30, and UC Berkeley housing experts are warning of a potential surge of evictions and homelessness, along with damaging economic shock waves.

Eastern and Western house mice took parallel evolutionary paths

The European house mouse has invaded nearly every corner of the Americas since it was introduced by colonizers a few hundred years ago, and now lives practically everywhere humans store their food. Yet in that relatively short time span — 400 to 600 mouse generations — populations on the East and West Coasts have changed their body size and nest building behavior in nearly identical ways to adapt to similar environmental conditions, according to a new study by biologists at the University of California, Berkeley.

After a blitz of police killings, reformers focus on the power of their unions

Across the nation, unions and their leaders have strongly defended officers against accusations of excessive violence, often directed against people of color. Cities are dangerous places, they say, and that justifies a warrior-like approach to policing. But in a series of interviews, Berkeley scholars said police unions have successfully used a range of tools, from the fine print in labor contracts to millions of dollars in political donations, to shield officers from accountability and promote hardline policing practices. While discipline is often secret and officers rarely lose their jobs, they say, cities have paid tens of millions of dollars in settlements with recent victims.

In calculating the social cost of methane, equity matters

What is the cost of one ton of a greenhouse gas? When a climate-warming gas such as carbon dioxide or methane is emitted into the atmosphere, its impacts may be felt years and even decades into the future – in the form of rising sea levels, changes in agricultural productivity, or more extreme weather events, such as droughts, floods, and heat waves. Those impacts are quantified in a metric called the “social cost of carbon,” considered a vital tool for making sound and efficient climate policies. Now a new study by a team including researchers from Lawrence Berkeley National Laboratory (Berkeley Lab) and UC Berkeley reports that the social cost of methane – a greenhouse gas that is 30 times as potent as carbon dioxide in its ability to trap heat – varies by as much as an order of magnitude between industrialized and developing regions of the world.

When parole, probation officers choose empathy, returns to jail decline

Heavy caseloads, job stress and biases can strain relations between parole and probation officers and their clients, upping offenders’ likelihood of landing back behind bars. On a more hopeful note, a new UC Berkeley study suggests that nonjudgmental empathy training helps court-appointed supervision officers feel more emotionally connected to their clients and, arguably, better able to deter them from criminal backsliding.

A $15 minimum wage would cost jobs, right? Probably not, economists say

Extensive research led by UC Berkeley economists and alumni has found that significant increases in the minimum wage have little, if any, impact on employers’ hiring decisions. In fact, the researchers say, a higher minimum wage can produce benefits not just for workers, but for their employers, their communities and the entire economy.

After COVID-19, work will never be ‘normal’ again

A year ago, just after Bay Area governments imposed a shelter-in-place order to check the spread of a mysterious new coronavirus, Cristina Banks worried about how she would work from home. She would miss her office at UC Berkeley’s Haas School of Business. She would miss interacting with colleagues and students. She would miss her books and her papers. Banks directs the Interdisciplinary Center for Healthy Workplaces, a global research center at Berkeley, and even in the ¬surpassing strangeness of the past year, she has continued to observe and analyze how the pandemic is changing our work — and changing us.

How fast is the universe expanding? Galaxies provide one answer.

Determining how rapidly the universe is expanding is key to understanding our cosmic fate, but with more precise data has come a conundrum: Estimates based on measurements within our local universe don’t agree with extrapolations from the era shortly after the Big Bang 13.8 billion years ago. A new estimate of the local expansion rate — the Hubble constant, or H0 (H-naught) — reinforces that discrepancy.

Glass frogs living near roaring waterfalls wave hello to attract mates

Most frogs emit a characteristic croak to attract the attention of a potential mate. But a few frog species add to their calls by visually showing off with the flap of a hand, a wave of a foot or a bob of the head. Conservation ecologist Rebecca Brunner has discovered that the glass frog Sachatamia orejuela can be added to the list of species that make use of visual cues in response to their acoustic environments. This is the first time a member of the glass frog family (Centrolenidae) has been observed using visual communication in this manner.

New study reveals how fences hinder migratory wildlife in the West

Each year, thousands of migratory mule deer and pronghorn antelope journey northwest from their winter homes to their summer homes in the mountainous landscape near Grand Teton National Park. But to reach their destination, these ungulates must successfully navigate the more than 6,000 kilometers (3,728 miles) of fencing that crisscrosses the region. That’s enough distance to span nearly twice the length of the U.S.-Mexico border.

Reawakened geyser does not foretell Yellowstone volcanic eruptions

When Yellowstone National Park’s Steamboat Geyser reawakened in 2018 after three and a half years of dormancy, some speculated that it was a harbinger of possible explosive volcanic eruptions within the surrounding geyser basin. A new study by geoscientists who study geysers throws cold water on that idea, finding few indications of underground magma movement that would be a prerequisite to an eruption. The geysers sit just outside the nation’s largest and most dynamic volcanic caldera, but no major eruptions have occurred in the past 70,000 years.
