A group of chemists, microbiologists, and ecologists has developed a molecular probe (a molecule designed to detect e.g. proteins or DNA inside an organism) that glows when a sugar is broken down. Writing in the journal JACS, the researchers describe how this innovation makes it possible to observe the microscopic competition between algae and the…
Genetic mutations that can cause disease become increasingly common in sperm as men grow older, and new evidence suggests this happens because certain DNA changes are actually favored during sperm production, according to new research. In a major study published on October 8 in Nature, scientists from the Wellcome Sanger Institute and the TwinsUK study…
Iron-deficiency anemia is a widespread health problem that often leads to fatigue, headaches, or even cravings for ice. Traditional oral iron supplements can help, but they often leave behind unabsorbed iron that irritates the digestive tract and triggers inflammation. Researchers reporting in ACS Applied Materials & Interfaces have developed a new type of supplement that…
Researchers at the University of California San Diego School of Medicine, working with the genetic testing company 23andMe, have pinpointed regions of the human genome linked to cannabis use. Their discoveries reveal new genetic connections to psychiatric, cognitive, and physical health, offering insights that could eventually guide prevention and treatment strategies for cannabis use disorder….
Researchers at the University of Maryland have identified the gene responsible for a rare type of wheat that forms three ovaries in each flower instead of just one. Because each ovary can grow into a grain, this finding could help boost the amount of wheat produced per acre. The study appeared on October 14, 2025,…
SuperAgers are people over 80 whose memory performs as well as someone 30 years younger, showing that exceptional cognitive health can last a lifetime. They tend to be highly social, maintaining strong relationships and active lifestyles, and their brains appear to resist the buildup of Alzheimer’s-related plaques and tangles that often cause memory loss. Ongoing…
Scientists have recently captured a rare look at the harsh winter conditions swirling above Mars’ north pole. Inside the planet’s polar vortex, temperatures drop dramatically — much colder than the air outside — and the continuous darkness of the long Martian winter allows ozone levels in the atmosphere to rise sharply. “The atmosphere inside the…
Scientists at The University of Western Australia’s node of the International Centre for Radio Astronomy Research (ICRAR) have made a remarkable discovery: a massive structure stretching about 185,000 light-years between two galaxies, NGC 4532 and DDO 137, located some 53 million light-years from Earth. According to a study published in the Monthly Notices of the…
People with advanced lung or skin cancer who received a COVID-19 mRNA vaccine within 100 days of beginning immunotherapy lived considerably longer than those who did not, according to new research. Scientists from the University of Florida and the University of Texas MD Anderson Cancer Center describe this as a milestone in more than a…
Men whose prostate cancer returns after surgery or radiation therapy may soon benefit from a powerful new treatment that has been shown in clinical trials to reduce the risk of death by more than 40%. Researchers tested a therapy that combines enzalutamide, an existing cancer drug, with standard hormone therapy. This approach significantly lowered death…
