Hidden geological process offsets carbon emissions from thawing permafrost

Scientists found that thawing permafrost can trigger increased rock weathering, a natural process that absorbs CO2 from the atmosphere. In some regions, this carbon uptake was strong enough to fully offset — or even surpass — river greenhouse gas emissions.

The secret language behind animal cooperation

Animals from different species often rely on surprisingly sophisticated communication to work together, whether finding food, cleaning parasites, or gaining protection. New research suggests these interspecies “conversations” are flexible, evolved, and far more important to life in nature than scientists once realized.

Think you're eating healthy? You may be missing this heart-protecting nutrient

Eating five servings of fruits and vegetables may not be enough if you're missing foods rich in flavanols, a group of compounds linked to better heart health. Researchers found that choices like blackberries, plums, apples, broad beans, cherries, and green tea can dramatically increase flavanol intake.

Scientists expected a black hole but found a neutrino factory powered by stars

A distant galaxy nicknamed Shadow Blaster may have revealed a surprising source of cosmic neutrinos: extreme star formation instead of a supermassive black hole. The discovery suggests that hidden, dust-filled starburst galaxies could account for a significant fraction of the Universe’s high-energy neutrinos.

Researchers found a Wordle strategy that wins 99% of the time

Researchers developed a Wordle-solving strategy that succeeds 99% of the time by focusing on information gain rather than likely answers. The method uses Shannon entropy to identify guesses that reveal the most about the hidden word. Each guess is designed to slash uncertainty and narrow the possibilities faster. The result significantly outperformed more traditional Wordle tactics.

New research links prenatal exposure to Pfas to later development of PMOS

Study suggests exposure to ‘forever chemicals’ may be a main driver of disease, formerly called PCOS, authors sayNew research for the first time links prenatal exposure to Pfas “forever chemicals” with the development of polyendocrine metabolic ovarian syndrome (PMOS) later in life.PMOS, formerly known as polycystic ovarian syndrome (PCOS), is estimated to impact about 13% of women. Many cases are undiagnosed, and the disease’s cause largely remains a mystery. Continue reading...

‘Termination shock’: trust our expert warnings on geoengineering’s planetary risks | Raymond Pierrehumbert, Julia Slingo, Michael Mann and Valerie Masson-Delmotte

Do we really want to play dice with our planet?A series in the Guardian recently declared “it’s time to talk about geoengineering.” So let’s talk about it. And let us start with some simple truths about this cluster of techno-optimistic “quick fixes” which purport to somehow offset our slow progress towards zeroing out planet-warming carbon emissions.Solar geoengineering proposals – reducing sunlight – have received the most attention, but a host of desperate schemes have been proposed in an eff

Einstein’s “biggest blunder” may finally have an explanation

Scientists have uncovered a surprising connection between quantum gravity and an exotic quantum state of matter that could explain why the universe isn’t expanding wildly fast. The study suggests that the very shape of space-time may protect the cosmological constant from disruptive quantum effects.

Black hole winds may be robbing giant galaxies of their future stars

Astronomers may be closing in on a long-standing cosmic mystery: why some of the universe’s biggest galaxies seem to have far fewer stars than expected. Using NASA- and JAXA-supported XRISM observations of a galaxy called NGC 4151, researchers found strong evidence that supermassive black holes can unleash powerful winds that blow away the raw material needed to make new stars.

Scientists may have uncovered a hidden trigger behind Alzheimer’s disease. Instead of plaques being the root cause, amyloid beta appears to interfere with tau, a protein that helps keep neurons functioning properly. This disruption could set off the damage that eventually leads to the disease’s most recognizable brain changes.
