New research uncovers the massive squid diet of Hawaiian pilot whales

9:13
Hawaiian short-finned pilot whales are surprisingly voracious hunters, diving hundreds of meters beneath the Pacific to snatch squid in the dark. By tagging and tracking eight whales, researchers uncovered just how much energy these deep-sea forays require—and how many squid the whales must eat to stay fueled. Their calculations reveal that each whale downs dozens to hundreds of squid per day, ad…

Princeton’s new quantum chip marks a major step toward quantum advantage

7:34
A Princeton team built a new tantalum-silicon qubit that survives for over a millisecond, far surpassing today’s best devices. The design tackles surface defects and substrate losses that have limited transmon qubits for years. Easy to integrate into existing quantum chips, the approach could make processors like Google’s vastly more powerful.

Physicists reveal a new quantum state where electrons run wild

7:01
Electrons can freeze into strange geometric crystals and then melt back into liquid-like motion under the right quantum conditions. Researchers identified how to tune these transitions and even discovered a bizarre “pinball” state where some electrons stay locked in place while others dart around freely. Their simulations help explain how these phases form and how they might be harnessed for adva…

Astronomers unveil the surprising hidden geometry of a supernova

5:55
Astronomers have, for the first time, recorded the moment a star’s explosion broke through its surface. The nearby supernova, SN 2024ggi, revealed a surprisingly olive-shaped blast when studied with ESO’s Very Large Telescope. The discovery helps scientists better understand the forces that drive massive stars to explode and underscores how quick international cooperation can lead to groundbreaki…

Astronomers discover thousands of hidden siblings of the “Seven Sisters”

5:55
The “Seven Sisters” have far more relatives than anyone imagined. Using NASA and ESA space telescopes, astronomers found thousands of hidden stars linked to the Pleiades, forming a colossal stellar complex. The discovery expands the cluster’s size by a factor of 20 and offers a new way to trace the shared origins of stars—including our own Sun.

GLP-1 drugs like Ozempic deliver huge weight loss but new research reveals a hidden catch

4:50
GLP-1 drugs like tirzepatide and semaglutide offer powerful weight-loss effects but come with unanswered questions about long-term safety, side effects, and global accessibility. Researchers stress the need for independent studies before these treatments can be fully embraced worldwide.

Melanoma rates are spiking fast in these 15 Pennsylvania counties

18:24
Penn State scientists identified a striking rise in melanoma across several Pennsylvania counties dominated by cropland and herbicide use. The elevated risk persisted even after factoring in sunlight, suggesting an environmental influence beyond the usual expectations. Researchers warn that drifting chemicals may expose nearby residents, not just farm workers.

AI creates the first 100-billion-star Milky Way simulation

18:24
Researchers combined deep learning with high-resolution physics to create the first Milky Way model that tracks over 100 billion stars individually. Their AI learned how gas behaves after supernovae, removing one of the biggest computational bottlenecks in galactic modeling. The result is a simulation hundreds of times faster than current methods.

Microquasars emerge as the Milky Way’s most extreme particle engines

18:24
LHAASO has uncovered that micro-quasars, black holes feeding on companion stars, are powerful PeV particle accelerators. Their jets produce ultra-high-energy gamma rays and protons that exceed long-held expectations. Precise cosmic-ray measurements reveal a new high-energy component, suggesting multiple sources within the Milky Way. These findings finally tie the “knee” structure to black hole je…

Extreme-pressure experiment reveals a strange new ice phase

18:24
Researchers at KRISS observed water’s rapid freeze–melt cycles under ultrahigh pressure and discovered Ice XXI, the first new ice phase found in decades. Using advanced high-pressure tech and microsecond XFEL imaging, they uncovered complex crystallization pathways never seen before. Ice XXI’s structure resembles the high-pressure ice found inside Jupiter and Saturn’s moons, hinting at planetary …

Scientists find a surprising link between lead and human evolution

18:23
Researchers found that ancient hominids—including early humans—were exposed to lead throughout childhood, leaving chemical traces in fossil teeth. Experiments suggest this exposure may have driven genetic changes that strengthened language-related brain functions in modern humans.

Neuroscientists find immune cells that may slow aging

18:23
A newly recognized set of T helper cells seems to guard against aging by eliminating harmful senescent cells. Their presence in supercentenarians suggests they may be a key to maintaining a healthier, age-balanced immune system.

Chimps shock scientists by changing their minds with new evidence

16.listopadu
Chimps may revise their beliefs in surprisingly human-like ways. Experiments showed they switched choices when presented with stronger clues, demonstrating flexible reasoning. Computational modeling confirmed these decisions weren’t just instinct. The findings could influence how we think about learning in both children and AI.

Dark matter acts surprisingly normal in a new cosmic test

16.listopadu
Dark matter may be invisible, but scientists are getting closer to understanding whether it follows the same rules as everything we can see. By comparing how galaxies move through cosmic gravity wells to the depth of those wells, researchers found that dark matter appears to behave much like ordinary matter, obeying familiar physical laws. Still, the possibility of a hidden fifth force lingers, o…

A single beam of light runs AI with supercomputer power

16.listopadu
Aalto University researchers have developed a method to execute AI tensor operations using just one pass of light. By encoding data directly into light waves, they enable calculations to occur naturally and simultaneously. The approach works passively, without electronics, and could soon be integrated into photonic chips. If adopted, it promises dramatically faster and more energy-efficient AI sy…
