(Natural News) When your dog looks up at you with its mouth open wide and its lips pulled up at the corners, is it really smiling at you? Despite humans having over 30,000 years of history with dogs, the answer is still unclear. But researchers believe they are getting close to finding the answer. A group of neuroscientists from […]

(Natural News) Want to know what ancient Middle Eastern beer tastes like? Try asking this team of researchers from Israel: In a study published in mBio, microbiologists and archeologists from the Israel Antiquities Authority and four local universities used yeast strains that lay dormant for thousands of years to brew potable “ancient beers.” For the multi-layered study, researchers isolated yeast […]

(Natural News) The triangle-weaver spider, scientifically known as Hyptiotes cavatus, looks and acts like your friendly, neighborhood house spider at first glance. The most it usually does in a day is build a web and wait for dinner to fall for its trap. However, unlike a normal spider, this particular arachnid does something unusual when a prey finds […]

(Natural News) Like any ancient Roman city, paved stone covered many of the streets of Pompeii. However, it recently came to light that workers – who were possibly slaves – repaired damaged parts by pouring molten iron into the ruts. Once the iron cooled, it filled up the ruts carved into the paved stone street by the […]

(Natural News) People can now tap snowfall for electricity, thanks to triboelectric nanogenerators that collect electrical energy from innocuous activities like footsteps and raindrops. The new energy harvester, developed by the University of California, Los Angeles (UCLA), is not only inexpensive but light as well – matching the thinness and flexibility of a plastic sheet. “The device […]

(Natural News) The medial zone of the Earth’s three-layered interior, the mantle is itself divided into upper and lower parts. Most experts believe that the lower mantle is dormant, but a recent European study found greater signs of dynamic activity in the region. The lower mantle starts 410 miles (660 km) beneath the crust of […]

(Natural News) Numerous studies show that the brain can repair and renew nervous tissue. People may support these natural processes by eating sulforaphane-rich foods like broccoli. Neuroscience experts previously believed that the brain cannot repair damaged neurons. However, a study conducted by MIT researcher Joseph Altman in the 1960s showed that the brains of adult rats, adult guinea pigs, […]

(Natural News) Scientists have long believed that bidirectional communication exists between the gut and the brain. In fact, evidence suggesting that the gut microbiota — the diverse community of microbes living in the human gut — interacts with the central nervous system (CNS) and influences brain function has increased over the years. Recent studies even propose that this […]

(Natural News) Indian gooseberries (Phyllanthus emblica) possess antioxidant and anti-inflammatory properties that help support healthy metabolism. Researchers from Nizam’s Institute of Medical Sciences (NIMS) in India evaluated their ability to reduce endothelial dysfunction and prevent the onset of metabolic syndrome. They published their findings in the scientific journal BMC Complementary and Alternative Medicine. Endothelial dysfunction contributed […]

(Natural News) Researchers at the National Institutes of Health (NIH) and their collaborators find another way to prevent heart attacks. In an animal study published in the journal Science Signaling, the researchers found that two proteins that bind to stress hormones work synergistically to keep the heart healthy. These proteins are stress hormone receptors called […]
