Researchers find how plants survive without sunlight or sex

6:37
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 bi…

Indoor tanning triples melanoma risk and seeds broad DNA mutations

6:37
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.

Researchers identify viral suspects that could be fueling long COVID

6:37
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.

Male bonobos use hidden clues to boost mating success

17:25
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 max…

Scientists finally uncovered why the Indus Valley Civilization collapsed

17:25
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 widespre…

Harvard gut discovery could change how we treat obesity and diabetes

17:25
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.

A grad student’s wild idea triggers a major aging breakthrough

17:25
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 collabora…

Natural compound supercharges treatment for aggressive leukemia

15:44
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…

AI finds a hidden stress signal inside routine CT scans

15:44
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 watched a sleeping neutron star roar back to life

15:44
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.

New quantum antenna reveals a hidden terahertz world

14:36
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…

A clear new material could make windows super efficient

14:36
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.

Webb finds a hidden atmosphere on a molten super-Earth

14:36
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.

The brain switch that could rewrite how we treat mental illness

13.prosince
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 ke…

Ozempic may offer a surprising bonus benefit for brain health

13.prosince
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 understan…
