Utility companies are promising to spare us from AI’s energy bill
In the face of backlash to concerns the AI boom will increase consumer electricity bills, the largest utility companies and data center developers in the US are now promising to do something about it. The Wall Street Journal reports that nearly 200 organizations have signed Presi
A hidden “switch-off” signal could predict solar storms seven years early
A newly discovered turning point in the Sun’s 11-year cycle could allow scientists to predict future solar activity years earlier than before. At this “switch-off” point, the most violent space weather abruptly ends, and the remaining number of sunspots offers clues about the nex
Scientists found mystery bacteria inside one of the ocean’s most elusive whales
Scientists studying decades of pygmy sperm whale strandings have uncovered three previously unknown types of Helicobacter bacteria hiding in the animals’ stomachs. All four infected whales showed serious digestive damage, including inflammation, ulcers, scarring, and parasite inf
New molecular map reveals how the flu virus hijacks human cells
Scientists uncovered how influenza A commandeers human cells, including a surprising strategy that dissolves tiny structures in the nucleus and releases proteins the virus may use to reproduce. The detailed molecular map could reveal new drug targets and help researchers study da
This food compound may help vaccines work better in older adults
A naturally occurring compound found in foods such as wheat germ, mushrooms, and aged cheese may help older adults build stronger protection after vaccination. In a small pilot trial, researchers gave spermidine supplements to adults over 65 following their third COVID-19 vaccine
Dying Sun-like stars may kick themselves through space
Dying Sun-like stars may not fade away quietly. As blobs of gas erupt unevenly from their swollen surfaces, each burst gives the star a tiny push in the opposite direction. Thousands of these random kicks could eventually break apart distant stellar pairs or, in rare cases, drive
New quantum gravity theory links entropy, dark energy, and life
A new theoretical study offers a possible explanation for how the Universe can grow more complex without violating the second law of thermodynamics. Using a quantum gravity framework called Gravity from Entropy, mathematician Ginestra Bianconi found that the Universe’s total entr
Millions face long-term coastal flooding risk in UK without climate action, scientists war
A ‘reasonable worst-case scenario’ suggests need for large-scale movement of populations away from reshaped coastUp to 13 million people in the UK face the long-term risk of coastal flooding due to the climate crisis, scientists have warned, with a “reasonable worst-case scenario
Watching too much TV in midlife may shrink the brain
Watching television very often in midlife may be linked to troubling brain changes decades later. In a study of about 1,700 adults, frequent TV viewers later showed smaller brain regions involved in memory, decision-making, and visual processing, along with more signs of damage i
Ancient mystery on K’gari as world’s largest sand island lakes dried up during rainy era
Ancient sediment reveals that some of K’gari’s deepest lakes vanished around 7,500 years ago, despite unusually heavy rainfall. The surprising discovery suggests changing winds and future climate shifts could threaten the sacred lakes known as the Eyes of K’gari.
Astronomers find the first atmosphere on a rocky world in the habitable zone
Astronomers have found the first confirmed atmosphere around a rocky planet in another star’s habitable zone. The planet, LHS 1140 b, revealed its atmosphere through helium slowly leaking into space. Located 48 light-years away, the world may have preserved its atmosphere for bil
