In the arid Mojave Desert, small burrowing mammals like the cactus mouse, the kangaroo rat and the white-tailed antelope squirrel are weathering the hotter, drier conditions triggered by climate change much better than their winged counterparts, finds a new study published today in Science.

Social media disinformation, climate change debates, foreign interference in elections — some of the defining themes of recent American politics seem only loosely connected. But underlying the headlines is a single, troubling theme: The nation’s political process is suffering a historic level of instability. A new initiative headed by Janet Napolitano will bring Berkeley faculty, researchers and students from across disciplines into the new Center for Security in Politics.

To support research that has the potential to forge new paths in the physical sciences, UC Berkeley launched the Heising-Simons Faculty Fellows program. Through a generous gift from the Heising-Simons Family Fund, early- and mid-career faculty members working in geology and geophysics, materials sciences and materials chemistry, astronomy and physics will have the opportunity to apply for five-year $1 million fellowships to pursue basic science research that could lead to paradigm-shifting discoveries.

Anyone who has tried and failed to meditate knows that our minds are rarely still. But where do they roam? New research led by UC Berkeley has come up with a way to track the flow of our internal thought processes and signal whether our minds are focused, fixated or wandering.

Randy Katz, a computer scientist and Wi-Fi pioneer who served as the University of California, Berkeley’s vice chancellor for research for three years, during which time he shepherded the campus through a year-long phased reopening after a pandemic shutdown, will step down on June 30.

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.

The Department of African American Studies is excited to announce that it has been selected as one of sixteen recipients of the Andrew W. Mellon Foundation’s Just Futures grant. This grant is a collaborative effort to address racial inequality through new humanities-based research & solutions.

Apart from black holes, magnetars may be the most extreme stars in the universe. With a diameter less than the length of Manhattan, they pack more mass than that of our sun, wield the largest magnetic field of any known object — more than 10 trillion times stronger than a refrigerator magnet — and spin on their axes every few seconds.

Biologists used crystallography performed at Berkeley Lab’s Advanced Light Source to reveal the new virus’s unusual protein structure.

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.

Americans, and people across the world, watched in shock and alarm yesterday as hundreds of right-wing extremists stormed the U.S. Capitol while Congress was certifying the Electoral College votes that produced a victory for Democrat Joe Biden and a defeat for President Donald Trump. But no one should have been surprised, says Lawrence Rosenthal, head of the Center for Right-Wing Studies at UC Berkeley.

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.

The more chaotic things get, the harder it is for people with clinical anxiety and/or depression to make sound decisions and to learn from their mistakes. On a positive note, overly anxious and depressed people’s judgment can improve if they focus on what they get right, instead of what they get wrong.

Imagine typing on a computer without a keyboard, playing a video game without a controller or driving a car without a wheel. A new device developed by engineers at the UC Berkeley can recognize hand gestures based on electrical signals detected in the forearm. The system, which couples wearable biosensors with artificial intelligence (AI), could one day be used to control prosthetics or to interact with almost any type of electronic device.

While many cities and eight states have banned single-use plastics, bags and other polyethylene packaging still clog landfills and pollute rivers and oceans. One major problem with recycling polyethylene, which makes up one-third of all plastic production worldwide, is economic: Recycled bags end up in low-value products, such as decks and construction material, providing little incentive to reuse the waste.

Whether at a birthday party in Brazil, a funeral in Kenya or protests in Hong Kong, humans all use variations of the same facial expressions in similar social contexts, such as smiles, frowns, grimaces and scowls, a new UC Berkeley study shows.
