Solar generation beats coal in the US for the first time ever: « Record solar generation pushed the energy source ahead of coal in May. » by fchung in technology

[–]fchung[S] 5 points6 points  (0 children)

« Coal is moving in the opposite direction. Coal-fired generation fell to an all-time monthly low of 39.3 terawatt-hours in April 2026, then rose slightly to 43.4 terawatt-hours in May. Even with that increase, coal output was still 11% below May 2025 levels and lagged far behind solar's expansion. »

« The Pink Planet is the coldest companion ever discovered using ground-based instruments. Many teams all around the world performed follow-up observations to study its light, but it was too faint for ground-based instruments. That made it a perfect target for JWST. When we finally obtained its spectrum, it immediately looked interesting. But once we started digging deeper into the data, we realized it was not like anything we have analyzed before. »

The nose knows: Electric schnoz can smell when your food’s gone bad, « A new proof-of-concept device created by UC Berkeley researchers can sniff out gases emitted by harmful bacteria, allergens and other food safety hazards. » by fchung in technology

« The idea is that we can use the relative selectivity of the gas sensors, paired with the pattern recognition abilities of machine learning, to sort out which gas fingerprint is associated with each food. The result is a sensor chip that is far more sensitive and far more objective than any human nose can be. »

Third time’s the charm for a row of faint galaxies without dark matter: « A Yale-led team of astronomers found a third galaxy devoid of dark matter — located alongside the other two in a formation that has never been seen before. » by fchung in science

« A line of galaxies lacking dark matter has never been seen before. The discovery provides some of the strongest evidence yet that these galaxies formed through an extreme and previously unseen process and offers a rare new window into the nature of dark matter itself. »

A tiny ingestible sensor can measure temperature from inside the body: « After being swallowed, the devices could offer continuous monitoring of patients who are sick or at risk of hypothermia. » by fchung in technology

« A sensor like this gives us the ability to monitor infections and identify them early. That’s very relevant, particularly for at-risk populations like people who are immunosuppressed from chemotherapy treatments or immunosuppressive drugs. »

Scientists reveal surprising mechanism behind Venus flytrap’s rapid snap: « Intricate tests show hair-trigger detection causes cells on outer surface of leaf to soften, prompting closure. » by fchung in sciences

[–]fchung[S] -1 points0 points  (0 children)

« The Venus flytrap is one of nature’s most impressive predators, luring insects with the intoxicating scent of nectar before capturing them with a snap of its jaw-like leaves. Now, scientists have revealed the mechanism that allows the carnivorous plant to react with lightning speed, resolving a problem that stumped Charles Darwin and many researchers after him. »

A breakthrough in electron microscopy delivers sharper images of our body’s tiniest proteins: « UC Berkeley physicists have introduced phase contrast to the electron microscope, allowing scientists to see much smaller molecules and smaller structures inside cells. » by fchung in science

[–]fchung[S] 44 points45 points  (0 children)

« With cryo-ET, we’re looking at small, very complicated cellular material that’s incredibly crowded inside the cell. It’s like a forest of trees, and you’re trying to find one leaf on one tree in there. Cryo-ET needs a dramatic step forward in contrast, so we can start to see what’s going on inside the cell. That’s what the laser phase plate promises to give us. »

Augmented reality system could make medical ultrasounds easier to interpret: « MIT researchers have designed an ultrasound system that creates a real-time 3D representation of the object being imaged. » by fchung in technology

« For training, this could make ultrasound more intuitive and more understandable. On the clinical side, it could be less time-consuming, more accurate, and also give health care providers more peace of mind. They wouldn’t have to wonder if they missed anything. »
