Invisible ID: How a single breath could reveal your health—and your identity

Scientists have discovered that your breathing pattern is as unique as a fingerprint and it may reveal more than just your identity. Using a 24-hour wearable device, researchers achieved nearly 97% accuracy in identifying people based solely on how they breathe through their nose. Even more intriguingly, these respiratory signatures correlated with traits like anxiety levels, sleep cycles, and body mass index. The findings suggest that breathing isn t just a passive process it might actively shape our mental and emotional well-being, opening up the possibility of using breath training for diagnosis and treatment.

The hunger switch in your nose: How smells tell your brain to stop eating

A team of scientists has discovered a direct link between the smell of food and feelings of fullness at least in lean mice. This brain circuit, located in the medial septum and triggered by food odors, helps animals eat less by making them feel satiated even before taking a bite. But intriguingly, obese mice lacked this response, highlighting how excess weight may interfere with this satiety mechanism. The finding could have major implications for how we think about the role of smell in appetite and offer new strategies to combat overeating.

Pincer plot twist: How female earwigs evolved deadly claws for love and war

Female earwigs may be evolving exaggerated weaponry just like males. A study from Toho University found that female forceps, once assumed to be passive tools, show the same kind of outsized growth linked to sexual selection as the male's iconic pincers. This means that female earwigs might be fighting for mates too specifically for access to non-aggressive males challenging long-standing assumptions in evolutionary biology.

AI sees through chaos—and reaches the edge of what physics allows

Scientists have uncovered how close we can get to perfect optical precision using AI, despite the physical limitations imposed by light itself. By combining physics theory with neural networks trained on distorted light patterns, they showed it's possible to estimate object positions with nearly the highest accuracy allowed by nature. This breakthrough opens exciting new doors for applications in medical imaging, quantum tech, and materials science.

Planets may start forming before their stars are even done

Planets may begin forming much earlier than scientists once believed during the final stages of a star s birth, not afterward. This bold new model, backed by simulations from researchers at SwRI, could solve a long-standing mystery: why so many exoplanet systems have tight clusters of similarly sized planets orbiting close to their stars. These compact systems seem to emerge naturally if planets start forming amid the swirling chaos of gas and dust still feeding the star.

New evidence reveals advanced maritime technology in the philippines 35,000 years ago

In a bold reimagining of Southeast Asia s prehistory, scientists reveal that the Philippine island of Mindoro was a hub of human innovation and migration as far back as 35,000 years ago. Advanced tools, deep-sea fishing capabilities, and early burial customs show that early humans here weren t isolated they were maritime pioneers shaping a wide-reaching network across the region.

Cannabis use among seniors surges 46% in two years—Study reveals

Cannabis use among older Americans has climbed dramatically, with 7% of adults 65 and older now reporting recent use. This rise isn't just in numbers but also in diversity older users today are more likely to be women, college-educated, and higher-income. Researchers suggest legalization and growing social acceptance are contributing factors, especially in states with medical marijuana laws. The trend is especially notable among those with chronic illnesses, raising both opportunities and concerns for medical professionals trying to balance symptom relief with the complexities of aging.

The Hidden DNA Repair System That Could Transform Cancer Treatment

A powerful new discovery reveals that Nup98 a protein once thought to only ferry molecules through the nucleus plays a vital role in safeguarding the most vulnerable areas of DNA. By forming droplet-like 'bubbles' around damaged DNA within dense regions called heterochromatin, Nup98 safely escorts the damaged segments to repair zones and times the involvement of risky repair proteins. This precise choreography prevents genetic errors that could trigger cancer or speed up aging.

Two plant species invent the same chemically complex and medically interesting substance

The biosynthesis of the great variety of natural plant products has not yet been elucidated for many medically interesting substances. In a new study, an international team of researchers was able to show how ipecacuanha alkaloids, substances used in traditional medicine, are synthesized. They compared two distantly related plant species and were able to show that although both plant species use a comparable chemical approach, the enzymes they need for synthesis differ and a different starting material is used. Further investigations revealed that the biosynthetic pathways of these complex chemical compounds have developed independently in the two species. These results help to enable the synthesis of these and related substances on a larger scale for medical use.
