A newly discovered species of Bartonella bacteria in Brazil’s Amazon sand flies shares DNA similarities with dangerous Andean strains. Scientists stress the need for further studies to see if it can infect humans and spread beyond its known regions.

For decades, scientists have puzzled over why lunar rocks show signs of strong magnetism when the moon itself has no global magnetic field today. New simulations suggest the answer may lie in a powerful asteroid impact billions of years ago.

Sucralose, the sugar substitute in many diet products, may weaken cancer immunotherapy by altering gut bacteria and reducing arginine levels needed for immune cells. But supplementation with arginine or citrulline could counteract this effect, pointing to new clinical trial possibilities.

Satellite data reveals sea-level rise has unfolded almost exactly as predicted by 1990s climate models, with one key underestimation: melting ice sheets. Researchers stress the importance of refining local projections as seas continue to rise faster than before.

Hidden fat wrapped around organs, known as visceral fat, has now been linked to faster heart aging. Using AI and imaging from more than 21,000 people in the UK Biobank, scientists found that this invisible belly fat accelerates stiffening and inflammation of the heart, while fat stored around hips and thighs may actually protect women.

Getting a smartphone before age 13 may drastically increase the risk of poor mental health later in life, according to data from more than 100,000 people. Early use is linked to suicidal thoughts, aggression, and detachment, largely driven by social media, cyberbullying, and lost sleep. Researchers urge urgent action to restrict access and protect young minds.

Two tiny pterosaurs, preserved for 150 million years, have revealed a surprising cause of death: violent storms. Researchers at the University of Leicester discovered both hatchlings, nicknamed Lucky and Lucky II, with broken wings—injuries consistent with being tossed through the air by powerful gusts. These storms not only claimed their lives but also created the rare conditions that preserved them so perfectly in the Solnhofen limestones.

A team of chemists has discovered how to transform PET plastic waste into BAETA, a material that captures CO2 with remarkable efficiency. Instead of ending up as microplastics in the environment, discarded bottles and textiles could become tools to combat climate change. The method is energy-friendly, scalable, and potentially lucrative, offering industries both sustainability and practicality.

Scientists at the University of Tokyo have unveiled “gold quantum needles,” a newly discovered nanocluster structure formed under unusual synthesis conditions. Unlike typical spherical clusters, these elongated, pencil-shaped formations display unique quantum behaviors and respond to near-infrared light, making them promising tools for biomedical imaging and energy applications.

Ghost sharks have evolved rows of true teeth on a bizarre forehead rod used for mating. Fossil and genetic evidence revealed the tenaculum’s teeth develop the same way as those inside the mouth, offering a striking example of evolution’s ability to repurpose biological tools.

UC Santa Barbara researchers project that human impacts on oceans will double by 2050, with warming seas and fisheries collapse leading the charge. The tropics and poles face the fastest changes, and coastal regions will be hardest hit, threatening food and livelihoods worldwide.

Scientists have created a transparent solar coating that turns ordinary windows into clean energy generators without affecting clarity. Using cholesteric liquid crystal layers, the coating redirects polarized sunlight to the window edges where solar cells collect it. A small prototype already powered a fan, and full-sized windows could boost efficiency 50-fold while cutting the need for costly photovoltaic cells.

A hidden quantum geometry that distorts electron paths has finally been observed in real materials. This “quantum metric,” once thought purely theoretical, may revolutionize electronics, superconductivity, and ultrafast devices.

Scientists found that Red Sea corals can endure warming seas but grow much smaller and weaken under long-term heat stress. Though recovery is possible in cooler months, rising global temperatures may outpace their resilience, endangering reefs and the people who depend on them.

Seagrass, a vital coastal ecosystem, may be one of the planet’s best natural carbon sponges—but its fate depends on how we manage nutrients like nitrogen and phosphorus. While moderate nutrient input can supercharge seagrass growth and boost carbon storage, too much—especially nitrogen—fuels phytoplankton that block sunlight and devastate seagrass beds.

Scientists have uncovered microbial DNA preserved in mammoth remains dating back more than one million years, revealing the oldest host-associated microbial DNA ever recovered. By sequencing nearly 500 specimens, the team identified ancient bacterial lineages—including some linked to modern elephant diseases—that coexisted with mammoths for hundreds of thousands of years. These discoveries shed light on the deep evolutionary history of microbes, their role in megafaunal health, and how they may have influenced adaptation and extinction.

A large Brazilian study following more than 12,000 middle-aged adults found that those consuming the most artificial sweeteners—commonly found in diet sodas, flavored waters, and processed snacks—experienced significantly faster declines in memory and thinking skills. The effect was equivalent to about 1.6 years of extra brain aging, with the strongest impact seen in people under 60 and those with diabetes.

Scientists have uncovered a surprising way Parkinson’s disease may start: tiny toxic proteins that punch holes in brain cells like revolving doors. Instead of causing instant collapse, these flickering pores slowly weaken the cells, which could explain the gradual onset of symptoms.

New research reveals that carbon made it possible for Earth’s molten core to freeze into a solid heart, stabilizing the magnetic field that protects our planet. Without it, Earth’s deep interior — and life above — might look very different.

Meal timing shifts with age, and researchers found that eating breakfast later is tied to depression, fatigue, sleep problems, and an increased risk of death. Monitoring when meals are eaten could provide an easy health marker for aging adults.
