Researchers discovered that tanning beds cause widespread, mutation-laden DNA damage across almost all skin, explaining the sharply increased melanoma risk. Single-cell genomic analysis revealed dangerous mutations even in sun-protected regions. Survivors’ stories underscore how early tanning habits have lifelong consequences. The findings push for stricter policies and clear public warnings. Read more ›

The study reveals how Balanophora plants function despite abandoning photosynthesis and, in some species, sexual reproduction. Their plastid genomes shrank dramatically in a shared ancestor, yet the plastids remain vital. Asexual reproduction appears to have evolved repeatedly, helping the plants survive in isolated, humid forest habitats. The research highlights surprising resilience in these bizarre parasitic species. Read more ›

Scientists are uncovering a new possibility behind long COVID’s stubborn symptoms: hidden infections that awaken or emerge alongside SARS-CoV-2. Evidence is mounting that viruses like Epstein-Barr and even latent tuberculosis may flare up when COVID disrupts the immune system, creating lingering fatigue, brain fog, and other debilitating issues.

Scientists found that certain molecules made by gut bacteria travel to the liver and help control how the body uses energy. These molecules change depending on diet, genetics, and shifts in the microbiome. Some even improved insulin response in liver cells when tested in the lab. The findings could open the door to new ways of preventing or managing obesity and diabetes. Read more ›

A series of century-scale droughts may have quietly reshaped one of the world’s earliest urban civilizations. New climate reconstructions show that the Indus Valley Civilization endured repeated long dry periods that gradually pushed its people toward the Indus River as rainfall diminished. These environmental stresses coincided with shrinking cities, shifting settlements, and eventually widespread deurbanization. Rather than a dramatic collapse, the civilization appears to have faded slowly under relentles Read more ›

Male bonobos have an impressive ability to detect when females are most fertile, even though the usual visual cues are unreliable. Researchers tracking wild bonobos in the Congo discovered that males skillfully interpret a mix of swelling timing and a female’s reproductive history to pinpoint the optimal moment for mating. By blending these clues, they overcome nature’s misleading signals and maximize their chances of fathering offspring. Read more ›

Senescent “zombie” cells are linked to aging and multiple diseases, but spotting them in living tissue has been notoriously difficult. Researchers at Mayo Clinic have now taken an inventive leap by using aptamers—tiny, shape-shifting DNA molecules—to selectively tag these elusive cells. The project began as an offbeat conversation between two graduate students and quickly evolved into a collaborative, cross-lab effort that uncovered aptamers capable of binding to unique surface proteins...

Forskolin, a plant-derived compound, shows surprising potential against one of the most aggressive forms of leukemia. Researchers discovered that it not only stops cancer cells from growing but also makes them far more vulnerable to chemotherapy by preventing them from pumping out the drugs meant to kill them. Experts say this dual action could help create safer, more powerful AML treatments with fewer harsh side effects. Read more ›

Researchers used a deep learning AI model to uncover the first imaging-based biomarker of chronic stress by measuring adrenal gland volume on routine CT scans. This new metric, the Adrenal Volume Index, correlates strongly with cortisol levels, allostatic load, perceived stress, and even long-term cardiovascular outcomes, including heart failure risk.

Astronomers tracked a decade of dramatic changes in P13, a neutron star undergoing supercritical accretion. Its X-ray luminosity rose and fell by factors of hundreds while its rotation rate accelerated. These synchronized shifts suggest the accretion structure itself evolved over time. The findings offer fresh clues to how ultraluminous X-ray sources reach such extreme power. Read more ›

Webb’s latest observations reveal a hellish world cloaked in an unexpected atmosphere: TOI-561 b, an ultra-hot rocky planet racing around its star in under 11 hours. Despite being blasted by intense radiation that should strip it bare, the planet appears to host a thick layer of gases above a global magma ocean, making it far less dense than expected. Read more ›

Researchers at the University of Warsaw have unveiled a breakthrough method for detecting and precisely calibrating terahertz frequency combs using a quantum antenna made from Rydberg atoms. By combining atomic electrometry with a powerful terahertz-to-light conversion technique, they achieved the first measurement of a single terahertz comb tooth—something previously impossible due to the limits of electronics and optical tools.

MOCHI uses microscopic, air-filled channels to stop heat in its tracks while remaining nearly crystal clear. If scaled up, it could transform windows into powerful energy savers and solar harvesters. Read more ›

A decade-long study of older women found that tea drinkers had slightly stronger bones, while moderate coffee drinking caused no harm. Heavy coffee intake—over five cups a day—was linked to lower bone density, especially in women who consumed more alcohol. Tea’s benefits may stem from catechins that support bone formation. The researchers say small daily habits could make a meaningful difference over time. Read more ›

Researchers analyzing ancient fossils from caves across Western Australia have uncovered a completely new species of bettong along with two new woylie subspecies—remarkable finds made bittersweet by signs that some may already be extinct. Read more ›

Scientists exploring how the brain responds to stress discovered molecular changes that can influence behavior long after an experience ends. They also identified natural resilience systems that help protect certain individuals from harm. These findings are opening the door to treatments that focus on building strength, not just correcting problems. The work is also fueling a broader effort to keep science open, independent, and accessible. Read more ›

A new analysis suggests that people with type 2 diabetes who use GLP-1 medications like Ozempic, Trulicity or Victoza may be less likely to develop epilepsy than those taking DPP-4 inhibitors. Semaglutide showed the strongest connection to lowered risk. Researchers caution that the findings show an association, not proof of cause and effect. More rigorous long-term studies are needed to understand the link. Read more ›

Researchers discovered that children who went back to school during COVID experienced far fewer mental health diagnoses than those who stayed remote. Anxiety, depression, and ADHD all declined as in-person learning resumed. Healthcare spending tied to these conditions also dropped. Girls showed the largest improvements, highlighting the importance of school-based structure and support. Read more ›

Scientists have discovered that Madagascar’s iconic Pinocchio chameleon is actually a distinct species now named Calumma pinocchio. DNA from both modern samples and centuries-old museum specimens also exposed another hidden species, Calumma hofreiteri. The study shows that the chameleons’ elongated snouts evolve surprisingly quickly, likely influenced by female mate choice. These findings highlight Madagascar as a hotspot of rapidly diversifying reptile life. Read more ›

Researchers used AI to pinpoint a little-known monkeypox protein that provokes strong protective antibodies. When the team tested this protein as a vaccine ingredient in mice, it produced a potent immune response. The discovery could lead to simpler, more effective mpox vaccines and therapies. It may also help guide future efforts against smallpox. Read more ›
