AI revives lost 3,000-year-old Babylonian hymn

19:47
Researchers have rediscovered a long-lost Babylonian hymn from 1000 BCE, using artificial intelligence to piece together fragments scattered across the world. The hymn glorifies ancient Babylon’s beauty, prosperity, and inclusivity, even describing women’s priestly roles — a rarity in surviving texts. Once a school favorite, it now provides a rare glimpse into everyday life and beliefs of the cit…

Entangled spins give diamonds a quantum advantage

19:47
UC Santa Barbara physicists have engineered entangled spin systems in diamond that surpass classical sensing limits through quantum squeezing. Their breakthrough enables next-generation quantum sensors that are powerful, compact, and ready for real-world use.

Tiny implant wipes out bladder cancer in 82% of patients

19:47
TAR-200, a small drug-releasing implant, wiped out tumors in most patients with high-risk bladder cancer. Its slow, consistent release of chemotherapy proved far more effective than traditional short-term treatments. The therapy may replace bladder removal surgery for many and has earned FDA Priority Review due to its impressive results.

Brain-like learning found in bacterial nanopores

17:22
Scientists at EPFL have unraveled the mystery behind why biological nanopores, tiny molecular holes used in both nature and biotechnology, sometimes behave unpredictably. By experimenting with engineered versions of the bacterial pore aerolysin, they discovered that two key effects, rectification and gating, stem from the pore’s internal electrical charges and their interaction with passing ions.…

This 14th century story fooled the world about the Black Death

17:21
Historians have traced myths about the Black Death’s rapid journey across Asia to one 14th-century poem by Ibn al-Wardi. His imaginative maqāma, never meant as fact, became the foundation for centuries of misinformation about how the plague spread. The new study exposes how fiction blurred with history and highlights how creative writing helped medieval societies process catastrophe.

Astronomers just solved the mystery of “impossible” black holes

17:21
New simulations suggest magnetic fields hold the key to forming black holes that defy known mass limits. When powerful magnetic forces act on a collapsing, spinning star, they eject vast amounts of material, creating smaller yet faster-spinning black holes. This process could explain the puzzling GW231123 collision and the existence of “forbidden” black holes.

Scientists turn body fat into bone to heal spinal fractures

12:02
Researchers in Osaka have found that stem cells from fat tissue can repair spinal fractures similar to those caused by osteoporosis. By turning these cells into bone-forming clusters and pairing them with a bone-rebuilding material, rats regained stronger, healthier spines. The approach could offer a safe, minimally invasive alternative for treating bone diseases in humans.

Scientists uncover a hidden universal law limiting life’s growth

12:02
Japanese researchers uncovered a universal rule describing why life’s growth slows despite abundant nutrients. Their “global constraint principle” integrates classic biological laws to show that multiple factors limit cellular growth in sequence. Verified through E. coli simulations, it provides a powerful new lens for studying living systems. The work could boost crop yields and biomanufacturing…

Running on little sleep? You’re twice as likely to get hurt

12:02
Researchers found that runners who sleep poorly face nearly double the injury risk compared to those who rest well. The study highlights that sleep is not just recovery—it’s a key factor in preventing injuries. They stress that runners should prioritize rest alongside training. Simple habits like consistent bedtimes and limiting screens can make a big difference.

Clearing brain plaques isn’t enough to heal Alzheimer’s

8:07
Japanese researchers found that lecanemab, an amyloid-clearing drug for Alzheimer’s, does not improve the brain’s waste clearance system in the short term. This implies that nerve damage and impaired clearance occur early and are difficult to reverse. Their findings underscore that tackling amyloid alone may not be enough to restore brain function, urging a broader approach to treatment.

Scientists find brain chemical tied to trauma and depression

10.listopadu
Researchers identified SGK1 as a key chemical connecting childhood trauma to depression and suicidal behavior. High SGK1 levels were found in the brains of suicide victims and in people with genetic variants linked to early adversity. Drugs that block SGK1 could offer a new kind of antidepressant, especially for patients resistant to SSRIs.

Goodbye cavities? This new toothpaste made from hair can heal enamel

10.listopadu
Scientists have found that keratin, the protein in hair and skin, can repair and protect tooth enamel. The material forms a mineralized layer that halts decay and restores strength, outperforming traditional fluoride. Made from sustainable sources like hair, it could soon be available in toothpaste or gels. The discovery could transform dentistry by turning waste into a powerful tool for regenera…

Hidden weakness makes prostate cancer self-destruct

10.listopadu
Researchers have discovered that prostate cancer depends on two key enzymes, PDIA1 and PDIA5, to survive and resist therapy. When blocked, these enzymes cause the androgen receptor to collapse, killing cancer cells and enhancing the effects of drugs like enzalutamide. They also disrupt the cancer’s energy system, striking it on multiple fronts. This breakthrough could open a new path to overcomin…

New research finds no clear link between acetaminophen (Tylenol) and autism

10.listopadu
A sweeping review of existing studies finds no solid evidence that using acetaminophen (Tylenol) during pregnancy increases the risk of autism or ADHD in children. Researchers found that previous reviews often relied on weak or biased data, and most did not properly account for genetic or environmental factors shared by families. When these factors were considered, any apparent link between aceta…

Archaeologists may have finally solved Peru’s strange “Band of Holes” mystery

10.listopadu
In Peru’s mysterious Pisco Valley, thousands of perfectly aligned holes known as Monte Sierpe have long puzzled scientists. New drone mapping and microbotanical analysis reveal that these holes may once have served as a bustling pre-Inca barter market—later transformed into an accounting system under the Inca Empire.
