Scientists have found a new way to learn about the habits of city residents by looking at their sewage. The technique, called wastewater‑based epidemiology, usually tracks drug use but now also measures food and drink markers. A fresh laboratory test can spot more than 40 different substances in raw
Scientists wondered if something as simple as yoga could help people break free from methamphetamine. The drug doesn’t just affect the brain—it weakens the body’s ability to recover, makes users feel on edge all the time, and traps them in cycles of wanting more. Most treatments use medicine or talk
Scientists have made a breakthrough that could protect chickens from three deadly diseases with just one shot. The vaccine uses a harmless strain of the Newcastle disease virus (NDV) as a carrier. Instead of the usual genes, they inserted pieces from a dangerous NDV strain that is common today
Scientists picked two closely related spiny lizard species to see if sex or birth method makes a bigger difference in how stable their body shapes grow. One species gives live birth and thrives in cool mountain air, while the other lays eggs and lives at slightly lower elevations. Researchers measur
Scientists have found a way to make the tiny particles that help fuel cells work better. Instead of mixing the metals together, they grow a thin layer of platinum on tiny cobalt tubes that already have holes in them. This “seeded growth” technique creates a one‑dimensional structure that looks like
Scientists have spent decades charting how our eyes, ears and skin send signals to the brain. The nose, with its thousands of scent sensors, seemed a chaotic maze. Most researchers thought the receptors were scattered randomly. Two research groups changed that view. They used DNA sequencin
Scientists often chase big ideas—like finding a perfect theory to explain the universe. One physicist, now famous for a $3 million prize, thinks humans might never reach that finish line. Why? Because nuclear war could finish us first. This isn’t just guesswork. The same person helped solve a major
Scientists recently dug deeper into the genetic roots of two ethnic groups in Sichuan, China. They studied 100 people from the Qiang and Yi communities. Their goal? To map out how these groups connect genetically to others nearby. The findings show big similarities between the Qiang, Yi, and other
Scientists studied a way to help rats with brain damage that mimics human cerebral palsy. They used tiny packages called exosomes, which come from stem cells. These vesicles carry useful signals that can calm inflammation and support brain repair. The team gave the exosomes to rats that had suffere
Scientists have figured out exactly which parts of a cobalt‑based material make it good at turning glycerol into useful energy. Instead of guessing, they built three similar crystals that differ only in the tiny details around cobalt atoms. The key discovery was that the reaction happens mainl
