Formaldehyde is used by the body to regulate epigenetic change, and it may suppress the body's attempts to prevent the expression or overexpression of certain genes.

Viruses of coral symbionts offers clues about deadly disease across coral reef communities.

New study analyzes the coexistence of humans and coyotes in San Francisco.

When it comes to the water side of 30x30, most programs focus primarily on conservation of oceans, but a new study by researchers argues that freshwater ecosystems must not be neglected.

Wildfires are an increasing threat to people's lives, property and livelihoods, especially in rural California communities. Cannabis, one of California's newer and more lucrative commercial crops, may be at a higher risk of loss from wildfire because it is mostly confined to being grown in rural areas, according to new research by scientists in the Department of Environmental Science Policy and Management at UC Berkeley.

Researchers in the Department of Plant and Microbial Biology (PMB) have uncovered the intricate molecular processes that precede reproduction in flowering plants. Published July 6 in Nature, the findings document a previously unknown molecular process that serves as a method of communication during fertilization. According to Professor Sheng Luan, chair of the PMB department and the paper’s senior author, the exact mechanism for signaling has previously eluded researchers.

At the University of California, Berkeley, a real and more down-to-earth mission to decode an unknown form of communication is underway. Linguist Gasper Begus and computer scientist Shafi Goldwasser are part of an international team of researchers attempting interspecies communication with sperm whales by deciphering their deafening, 200-plus decibel clicking sounds, or codas.

Human populations have waxed and waned over the millennia, with some cultures exploding and migrating to new areas or new continents, others dropping to such low numbers that their genetic diversity plummeted. In some small populations, inbreeding causes once rare genetic diseases to become common, despite their deleterious effects. A new analysis of more than 4,000 ancient and contemporary human genomes shows how common such “founder events” were in our history.

Salamanders that live their entire lives in the crowns of the world’s tallest trees, California’s coast redwoods, have evolved a behavior well-adapted to the dangers of falling from high places: the ability to parachute, glide and maneuver in mid-air.

Research conducted at UC Berkeley’s Central Sierra Snow Laboratory (CSSL) is providing a much-needed tool for state water managers that could help them prepare for potential flooding during rain-on-snow events in the Sierra Nevada.

Of the hundred or so known species of hyena — living and extinct — that stalked the earth, all have been meat eaters or omnivores except one, the aardwolf, which, mysteriously, eats termites. What happened in the history of fearsome hyenas that led one group to give up raw meat and turn to insects? Two fossil skulls of a 12- to 15-million-year-old hyena that once lived in the Gansu province of China may shed light on that mystery.

Researchers at UC Berkeley, in collaboration with the University of Washington, have developed a new way to measure properties of salty water that may help us better understand whether the icy moons in the far reaches of our solar system can support life.

Nature is vitally important to the U.S. economy but we tend to take it for granted, doing little to measure the nation’s wealth of natural resources or their economic impact. But at a high-level White House meeting Thursday, Berkeley scholar Solomon Hsiang said that advanced technology is creating powerful new tools for measuring nature’s resources and their economic value.
