A hidden Aloe vera compound takes aim at Alzheimer’s
Scientists have uncovered promising clues that compounds found in Aloe vera could play a role in fighting Alzheimer’s disease. Using advanced computer modeling, researchers discovered that beta-sitosterol—a natural plant compound—strongly interacts with two key enzymes involved in memory loss and co…
Gut bacteria can sense their environment and it’s key to your health
Your gut is home to trillions of bacteria that constantly “sense” their surroundings to survive and thrive. New research shows that beneficial gut microbes, especially common Clostridia bacteria, can detect a surprisingly wide range of chemical signals produced during digestion, including byproducts…
NASA scientists say meteorites can’t explain mysterious organic compounds on Mars
Scientists studying a rock sample collected by NASA’s Curiosity rover have uncovered something tantalizing: the largest organic molecules ever detected on Mars. The compounds — decane, undecane, and dodecane — may be fragments of fatty acids, which on Earth are most often linked to life. While non-l…
Ancient microbes may have used oxygen 500 million years before it filled Earth’s atmosphere
Life on Earth may have learned to breathe oxygen long before oxygen filled the skies. MIT researchers traced a key oxygen-processing enzyme back hundreds of millions of years before the Great Oxidation Event. Early microbes living near oxygen-producing cyanobacteria may have quickly used up the gas …
Frozen for 5,000 years, this ice cave bacterium resists modern antibiotics
Deep inside a Romanian ice cave, locked away in a 5,000-year-old layer of ice, scientists have uncovered a bacterium with a startling secret: it’s resistant to many modern antibiotics. Despite predating the antibiotic era, this cold-loving microbe carries more than 100 resistance-related genes and c…
Flea and tick treatments for dogs and cats may be harming wildlife
Flea and tick medications trusted by pet owners worldwide may have an unexpected environmental cost. Scientists found that active ingredients from isoxazoline treatments pass into pet feces, exposing dung-feeding insects to toxic chemicals. These insects are essential for nutrient cycling and soil h…
Hidden architecture inside cellular droplets opens new targets for cancer and ALS
Biomolecular condensates were long believed to be simple liquid blobs inside cells. Researchers have now uncovered that some are actually supported by fine protein filaments forming an internal scaffold. When this structure is disrupted, cells fail to grow and divide properly. The discovery suggests…
Scientists discover a bacterial kill switch and it could change the fight against superbugs
Drug-resistant bacteria are becoming harder to treat, pushing scientists to look for new antibiotic targets. Researchers have now discovered that several unrelated viruses disable a key bacterial protein called MurJ, which is essential for building the bacterial cell wall. High-resolution imaging sh…
Scientists just created chocolate honey packed with surprising health perks
Scientists in Brazil have transformed cocoa waste into a functional chocolate-infused honey packed with antioxidants and natural stimulants. Using ultrasound waves, they enhanced honey’s ability to pull beneficial compounds from cocoa shells—no synthetic solvents required. The process is considered …
Scientists discover the protein that malaria parasites can’t live without
Scientists have uncovered a crucial weakness in the malaria parasite that could open the door to new treatments. Researchers identified a protein called Aurora-related kinase 1 (ARK1) that acts like a traffic controller during the parasite’s unusual cell division process, ensuring its genetic materi…
Scientists discover oxygen tug of war inside plant cells
Plants constantly juggle oxygen inside their cells, but scientists have now discovered a surprising twist in how that balance works. Researchers at the University of Helsinki found that mitochondria—the cell’s energy generators—can actively pull oxygen away from chloroplasts, the structures responsi…
Senior NIH scientist, research fellow charged with bringing deactivated mpox virus into U.S.
A senior NIH scientist and his research fellow were charged with smuggling vials of deactivated mpox virus into the country from Africa and lying about it.
