Scientists at Karolinska Institutet in Sweden and the RIKEN Center for Brain Science in Japan have identified two brain receptors that help regulate the breakdown of amyloid beta, the protein that builds up in Alzheimer’s disease. Their findings suggest it may be possible to develop future medications that are both safer and more affordable than
For a long time, scientists knew of a “gravity hole” beneath Antarctica—an area with particularly weak gravitational force. Considering the various threats currently faced by the region, scientists are hoping to understand this anomaly better. At last, they may have a new lead. Perhaps unsurprisingly, any shifts in Antarctica’s gravity overlap with major shifts in
NASA will take another crack at fueling up its huge Artemis 2 moon rocket this week. The agency plans to load more than 700,000 gallons (2.65 million liters) of liquid hydrogen (LH2) and liquid oxygen (LOX) into Artemis 2’s Space Launch System (SLS) rocket on Thursday (Feb. 19), wrapping up a crucial two-day-long test called
Deep within the caves of New Mexico, researchers have uncovered a mysterious phenomenon that could change how scientists search for life beyond Earth. In 2018, a team of scientists, led by Hazel Barton from the University of Alabama and Lars Behrendt from Uppsala University, explored the Carlsbad Caverns, where they found bright green microbial colonies
Home Reef, a mid-ocean volcano in the Tonga archipelago, continues to build onto its modest land area. Volcanic activity ramped up in December 2025, marking the latest in a series of periodic eruptions that began in 2022. The eruption was ongoing as of mid-February 2026. Satellites are critical to monitoring volcanoes such as Home Reef
Vanishing lakes in southern Tibet may have triggered earthquakes in the region by “awakening” long-dormant faults in Earth’s crust, researchers say. The finding adds to evidence of an unexpectedly strong link between our planet’s climate and the geological activity deep beneath our feet. About 115,000 years ago, southern Tibet was home to enormous lakes, some
Scientists may be one step closer in their hunt for signs of past life on Mars after the Curiosity rover’s latest find. Nearly a year ago, the car-sized robot – one of two NASA rovers roaming the red planet – came across an intriguing rock sample that contained some interesting features. On the rock, Curiosity’s
Humanity’s plans for deep-space exploration hinge on the ability to use basic resources, such as water, to propel rockets to farther destinations in the solar system. Despite decades of experimentation, engineers are yet to power a spacecraft using a water-electrolysis engine. Enter General Galactic, a California-based startup that claims to be able to turn water
Tonight, the Moon has vanished completely, meaning we’ve reached the New Moon phase of the lunar cycle. With no features visible, the sky is completely dark tonight, but it also happens to be an annular solar eclipse, which occurs when the Moon passes between the Sun and Earth at its farthest point, too small to
Rivers are expected to follow the path of least resistance. Yet in northeastern Utah, the Green River slices through hard limestone and sandstone at Split Mountain and the Canyon of Lodore instead of diverting toward softer shale and mudstone to the west. The formation of this route, which stretches for more than 100 miles across
