According to a new study published in the journal Nature Neuroscience, a high-salt diet reduces resting blood flow to the brain and causes dementia in mice. The findings illuminate a potential target for countering harmful effects caused by excess salt consumption. This study is the first to unveil a gut-brain …

NASA’s long-running James Webb Space Telescope project is nearing completion, but it needs a lot of testing before the agency sends it up into space where any undetected issues could prove disastrous. Several months ago, the completed telescope optical hardware was loaded into a vacuum chamber and cooled to extremely …

A new species of turkey-sized herbivorous dinosaur being named Diluvicursor pickeringi has been unearthed in southeastern Australia.

NASA engineers have successfully demonstrated X-ray navigation in space — a capability that could revolutionize NASA’s ability in the future to pilot robotic spacecraft to the far reaches of our Solar System and beyond. This illustration shows NASA’s NICER mission at work aboard the International Space Station. Image credit: NASA’s …

Individuals have wide-ranging physiological responses to the same species of pathogen. Researchers have demonstrated that different strains of a given bacterial species can elicit unique adaptive immune responses in the same individual, suggesting that variation between bacterial strains can explain heterogeneity in patient infection vulnerability. Research from the Rockefeller University …

In a paper published in the journal Physical Review E, a duo of fluid dynamics experts proposes a solution to one of long-standing Martian mysteries. The research shows that wind vortices can produce the common Martian phenomenon of a stratified mound positioned downwind from the center of an ancient meteorite …

Australia is experiencing nearly record high temperature levels reaching simply over 116 degrees Fahrenheit. It’s been so hot that asphalt melted on a stretch of highway, and regional news outlets reported a surge in presence at Australian beaches as residents struggle to leave threats like heat fatigue and heat stroke. …

Worldwide warming fear-mongers made dire predictions just a few short years ago that mankind had actually experienced the “ end of snow “due to the fact that of what does it cost? human activity had warmed and changed the earth’s climate. Of course, as much of the United States was …

Astronomers have been puzzling over so-called fast radio bursts for several years now, but their unpredictable nature has hampered our attempts to understand this bizarre phenomenon. That’s why an object called FRB 121102 has been of such interest. Whatever this object is, it fires off fast radio bursts repeatedly. A …

We’ve known for years that there is at least some water ice on Mars, but it’s been hard to pin down where it is and how easy it would be to extract. New data from NASA’s Mars Reconnaissance Orbiter indicates there could be a lot of it in giant sheets …
