A team at the University of Hong Kong has developed a new “super steel” that can survive the harsh conditions needed to make green hydrogen from seawater. The material uses an unexpected double-protection mechanism that resists corrosion far better than conventional stainless steel. Even more impressive, it could replace costly titanium parts used in today’s hydrogen systems.

Scientists at the University of Rochester pulled off a remarkable experiment: they transferred a longevity-related gene from the famously long-lived naked mole rat into mice, and the mice ended up healthier and lived longer. The special gene boosts production of a substance called high molecular weight hyaluronic acid, which appears to protect against cancer, reduce inflammation, and support healthier aging. The modified mice showed stronger resistance to tumors, healthier guts, and lower levels of age-related inflammation.

Scientists have uncovered a striking brain difference linked to psychopathy: people with psychopathic traits were found to have a striatum — a brain region tied to reward, motivation, and decision-making — that was about 10% larger on average than those without such traits. Using MRI scans and psychological assessments on 120 participants, researchers connected this enlarged brain region to thrill-seeking, impulsive behavior, and a stronger drive for stimulation.

Scientists have uncovered a hidden “stop-scratching” signal in the nervous system that tells your brain when enough scratching is enough. The discovery centers on a molecule called TRPV4, which acts like part of an internal braking system for itch relief. In experiments involving chronic itch similar to eczema, mice missing this signal scratched less often—but when they did scratch, they couldn’t stop.

Rebooting the gut microbiome with bacteria from youth may help stop aging-related liver damage and even prevent liver cancer, according to new research in mice. Older mice that received their own preserved youthful microbiome showed less inflammation, reduced DNA damage, and no signs of liver cancer. Researchers also found that the treatment suppressed a cancer-linked gene called MDM2, making older mice biologically resemble younger ones.

A colossal underwater volcano in the South Pacific may have revealed a surprising new weapon against climate change. After the 2022 eruption of Hunga Tonga–Hunga Ha’apai, scientists detected enormous amounts of formaldehyde in the atmosphere — a telltale sign that methane, one of the planet’s most powerful greenhouse gases, was being destroyed. Researchers now believe volcanic ash mixed with salty seawater and sunlight created reactive chlorine particles that effectively “cleaned up” some of the methane released by the eruption itself.

Scientists have uncovered strong evidence that a major Atlantic Ocean current system tied to global climate is weakening. The slowdown has been detected across a vast region of the North Atlantic over nearly two decades. Since this ocean circulation helps regulate weather and temperatures, changes could affect storms, rainfall, sea levels, and even winter conditions in parts of Europe and North America.

Scientists have uncovered a hidden Antarctic threat that could accelerate global sea level rise far faster than expected. Deep beneath floating ice shelves, long channels carved into the ice appear to trap warmer ocean water, dramatically speeding up melting from below. Even regions of East Antarctica once considered relatively stable may be far more vulnerable than scientists realized. Researchers warn that current climate models may be missing this dangerous process entirely, meaning future sea level rise could be underestimated.

Scientists may have found a smarter, safer way to wipe out termites hiding inside homes. A chemical called bistrifluron prevents drywood termites from forming new exoskeletons during molting, killing entire colonies from within. In tests, it eliminated about 95% of termites while avoiding the toxic side effects of traditional fumigation. Researchers say the method could provide longer-lasting protection as termites spread into new areas.

Physicists may have just cracked open a hidden side of the quantum world. For decades, every known particle was thought to belong to one of two categories — bosons or fermions — but researchers have now shown that bizarre “in-between” particles called anyons could also exist in a one-dimensional system. Even more exciting, these strange particles may be adjustable, allowing scientists to tune their behavior in ways never before possible.

Scientists have taken a major step toward ultra-secure quantum communication by demonstrating a remarkably stable quantum encryption system that worked across more than 120 kilometers of optical fiber. Using tiny semiconductor quantum dots that emit single particles of light on demand, the team achieved one of the highest secure key rates yet for this type of technology while maintaining continuous operation for over six hours without manual adjustments.

Researchers have developed a stem cell-based model of the human intestine that may transform how new IBD treatments are discovered. After testing thousands of compounds, they identified glycyrrhizin — a natural substance found in black licorice — as a promising anti-inflammatory candidate. In both lab-grown tissue and mice, the compound reduced intestinal damage and cell death linked to IBD.

A major obstacle may be standing in the way of the next generation of ultra-tiny computer chips. Researchers discovered that many promising 2D materials lose their advantages because an invisible atomic-scale gap forms when they are combined with insulating layers. That tiny gap weakens electronic performance and could prevent further miniaturization. The team says new “zipper materials” that lock together more tightly may offer a path forward.

A new study shows that listening to your own favorite workout music can dramatically boost endurance. Cyclists exercising with self-selected songs lasted nearly 20% longer than when riding in silence, yet they didn’t feel more exhausted at the end. Researchers say music may help people stay in the “pain zone” longer without increasing perceived strain.

Fur seals may look like they’re simply resting after exhausting hunting trips at sea, but their bodies are secretly working overtime. Scientists discovered that hours after returning to land, the seals’ heart rates suddenly surge — sometimes doubling — as they recover from the intense physical stress of deep diving. The findings suggest that seals postpone much of their recovery until they’re safely ashore, likely flushing out lactic acid and rebuilding oxygen stores after days of nonstop diving and hunting.

Scientists in China discovered that ancient humans were making surprisingly advanced stone tools during a harsh ice age 146,000 years ago. The tools, created by Homo juluensis, show careful planning and complex thinking rather than simple stone-chipping. Researchers dated the site using tiny calcite crystals inside animal bones, revealing the tools are much older than expected. The discovery challenges the idea that human creativity only thrives in easy, prosperous times.

Scientists have uncovered a surprising secret hidden inside fat cells that could reshape how we think about obesity and metabolic disease. A protein called HSL, long believed to simply release stored fat when the body needs energy, turns out to have a second job deep inside the nucleus of fat cells—helping keep those cells healthy and balanced. Even more surprising, people and mice missing this protein don’t become obese as expected; instead, they lose fat tissue in a dangerous condition called lipodystrophy.

A common constipation drug may have unexpectedly unlocked a new way to slow chronic kidney disease — a condition that affects millions and often leads to dialysis. In a clinical trial involving 150 patients, researchers found that lubiprostone, a medication normally used to treat constipation, helped preserve kidney function in people with moderate CKD. Scientists traced the effect to changes in gut bacteria that boosted production of spermidine, a compound linked to healthier mitochondria and reduced kidney damage.

Scientists studying axolotls, zebrafish, and mice have uncovered a shared set of genes that may one day help humans regrow lost limbs. By identifying powerful “SP genes” involved in regeneration, researchers discovered that disabling these genes stopped proper bone regrowth in salamanders and mice. They then used a gene therapy inspired by zebrafish biology to partially restore regeneration in mice, marking a major step toward future treatments that could replace damaged limbs with living tissue instead of prosthetics.

Scientists have uncovered a surprising way to influence the bacteria living in our mouths — not by killing them, but by interrupting how they “talk” to each other. Researchers found that dental plaque bacteria use chemical signals to coordinate growth, and by blocking those signals, they were able to encourage healthier bacteria while reducing disease-linked microbes tied to gum disease. Even more intriguing, the bacterial conversations changed depending on oxygen levels above and below the gums, revealing an entirely new layer of complexity inside the mouth.
