MeerKAT’s direct detection of distant hydrogen emissions advances a way to map the universe without identifying galaxies individually. Astronomers using South Africa’s MeerKAT radio telescope have directly detected faint radio emissions from neutral hydrogen gas billions of light-years away. The signal traveled for roughly four to five billion years before reaching Earth, offering a way […]
Fighting Fire With Fire Could Save Giant Sequoias
Iconic trees in areas with controlled burns are four times as likely to survive extreme wildfires. Giant sequoias, the enormous trees native only to the western slopes of California’s Sierra Nevada, can live for more than 3,000 years. Yet thousands died when the Castle Fire in 2020 and the KNP Complex Fire in 2021 swept […]

Scientists Just Found a Hidden Factor That Could Trigger an Atlantic Ocean Collapse
Rapid warming could cause a major Atlantic Ocean current system to collapse, even at temperatures it could withstand under slower warming. The Atlantic Meridional Overturning Circulation, or AMOC, carries warm water from the tropics northward, redistributing heat around the planet and helping keep Western Europe relatively mild. New research suggests that warming could push this […]
Your Blood May Predict How Well a Vaccine Will Work
Hidden antibody patterns in your blood may reveal how well your immune system will respond to a vaccine before you get the shot. Before someone receives a COVID-19 vaccine, their blood may already offer clues to how strongly their immune system will respond. Some of those clues come from antibodies against other microbes, rather than […]

Scientists Find a Berry Compound That Helps Muscle Cells Burn Fat
Pterostilbene, a compound found naturally in some foods, affects how skeletal muscles process fats by stabilizing a protein called PPARδ and increasing its signaling activity. Pterostilbene, a natural compound found in blueberries, grapes, and other berries, may help muscle cells clear excess fat by protecting a protein that regulates how they use it. Researchers in […]
