Scientists have identified three Earth-sized planets orbiting two stars in the TOI-2267 system. Remarkably, planets transit around both stars — a first in astronomy. The system’s compact, cold nature defies conventional theories of planetary formation. Future studies using JWST and other advanced telescopes could reveal what these worlds are truly made of.

Researchers discovered that continents don’t just split at the surface—they also peel from below, feeding volcanic activity in the oceans. Simulations reveal that slow mantle waves strip continental roots and push them deep into the oceanic mantle. Data from the Indian Ocean confirms this hidden recycling process, which can last tens of millions of years.

In a first-of-its-kind study, scientists found that bumblebees can tell the difference between short and long light flashes, much like recognizing Morse code. The insects learned which signal led to a sweet reward, demonstrating an unexpected sense of timing. This ability may stem from a fundamental neural process, suggesting that even tiny brains have complex time-tracking mechanisms relevant to evolution and AI.

Researchers scanning soccer fans’ brains found that wins trigger bursts of reward activity while losses dampen control signals. The results show how loyalty and rivalry can override logic, turning competition into an emotional storm. The same brain circuits that fuel sports passion may also underlie political or social fanaticism. Early experiences, the study suggests, shape whether these circuits lead to healthy excitement or explosive reactions.

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. The team even built nanopores that imitate brain-like “learning,” hinting at future applications in bio-inspired computing and ion-based processors.

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 city that once ruled the world.

Texas A&M scientists have unlocked new potential for astatine-211, a rare and short-lived element, as a highly precise cancer-fighting isotope. Its alpha emissions destroy tumor cells while sparing healthy tissue, making it ideal for targeted therapy.

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.

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.

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.

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.

In the third quarter of 2025, solar projects representing about 20% of planned capacity reported a delay, a decrease from 25% in the same period in 2024, based on data compiled from multiple Preliminary Monthly Electric Generator Inventory reports.

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.

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 efficiency.

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.

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.

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.

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 regeneration.

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 overcoming drug resistance in advanced prostate cancer.

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 acetaminophen use and neurodevelopmental disorders largely disappeared.
