Tall flowers, dead shrubs, ephemeral lake: Death Valley has become a picture of climate whiplash

NBC NEWS - In California’s boom-and-bust climate, Death Valley has offered some of the strangest scenes over the past few years. Some of the area’s perennial creosote bushes died back during a severe drought that hampered the region through 2022. Then torrential downpours — from the remnants of Hurricane Hilary and subsequent storms — revived...

Increased CO2 is making wildfires more frequent by making plants grow faster

EARTH.COM - We tend to think of wildfires as being caused by hot weather and drought. And for good reason – those weather conditions make plants tinder-dry. But a new study from the University of California, Riverside is flipping that idea on its head. Turns out, the biggest culprit in mega wildfires might be something...

'One and Done': Scientists Develop Vaccine That May Fight Any Viral Strain

U.S. NEWS - Genetics-based “one-and-done” vaccines for the flu and COVID could prove more effective and easier to craft than current jabs, researchers report. These new vaccines would target viruses using a different response to infection than what is prompted by current vaccines, researchers said. “What I want to emphasize about this vaccine strategy is...

Exotic 'Einstein ring' suggests that mysterious dark matter interacts with itself

SPACE.COM - A fresh analysis of a remarkably massive yet compact galaxy from the early universe suggests that dark matter interacts with itself. The galaxy, JWST-ER1, which formed just 3.4 billion years after the Big Bang, was first spotted last October in images snapped by NASA's James Webb Space Telescope (JWST). At over 17 billion...

‘Solar-powered vacuum cleaners’: the native plants that could clean toxic soil

THE GUARDIAN - It almost looked like a garden. In Taylor Yard, a former railyard near downtown Los Angeles, volunteers knelt down to tend to scrubby plants growing in neat rows under the sweltering sun. But beneath the concrete of the 60-acre site overlooking the Los Angeles River, the soils were soaked with an assortment...

A Virus May Help Save The World’s Amphibians From Extinction

FORBES - A deadly fungus that is devastating frogs and toads around the world may in fact be vulnerable to a virus that can infect it. The fungus, Batrachochytrium dendrobatidis also known as Bd or the amphibian chytrid fungus, causes chytridiomycosis in amphibians. This fungus is a pathogen that infects and destroys the skin of...

Why the spread of organic farms may prompt growers to use more pesticide, not less

LOS ANGELES TIMES - To help California fight climate change, air quality regulators would like to see 20% of the state’s farmland go organic by 2045. That means converting about 65,000 acres of conventional fields to organic practices every year. “We expect an increase in organic in the future,” said study leader Ashley Larsen, a...
