Pangea, the ancient supercontinent that once united all seven continents, began breaking apart roughly 200 million years ago. That breakup shaped the modern world map. Now, researchers say the tectonic forces that split Pangea apart may eventually reverse course. According to a 2018 study published in Geological Magazine, there are four prevailing scenarios for how
According to the paper, “NASA has identified five hazards of space travel: space radiation; isolation and confinement; distance from Earth; gravity (or lack of gravity); and hostile environments.” And while we already know the human body can adapt to space travel in some ways, “including cardiovascular, fluid balance, and vestibular systems,” we also know “bone density,
Southern Californians out on Saturday night for Valentine’s Day took a break from staring longingly into each other’s eyes to gaze at something else: a SpaceX rocket blazing across the early evening Southland sky. SpaceX launched a Falcon 9 rocket on Saturday night from Vandenberg Space Force Base in California. The rocket carried 24 Starlink
CAPE CANAVERAL, Fla. (AP) — The International Space Station returned to full strength with Saturday’s arrival of four new astronauts to replace colleagues who bailed early because of health concerns. SpaceX delivered the U.S., French and Russian astronauts a day after launching them from Cape Canaveral. Last month’s medical evacuation was NASA’s first in 65
From roots to canopy, many trees can indeed tell if they are being eaten – and by whom. They have evolved extraordinary abilities to discern chewing by beetles and caterpillars, piercing and sucking by bugs, acoustic vibrations from grasshoppers, deer saliva, microbes left by various animals, even the stress signals released by nearby trees being
Cannibalism might seem like a rare and unnatural occurrence, but the behavior has arisen in several snake lineages throughout evolutionary history, often triggered by environmental stressors, scientists theorize. When researchers reviewed 500 reports of cannibalistic behavior across snake species, they found that cannibalism has evolved independently at least 11 times, according to a study published
Ten years ago, humanity detected its first gravitational wave. On 14 January 2025, we detected the clearest one yet and it’s teaching us new things about the fundamental laws governing our universe. The signal, designated GW250114, arrived at the twin Laser Interferometer Gravitational Wave Observatories in the United States carrying the unmistakable signature of two
Jupiter, the largest planet in our Solar System, has just gotten a bit smaller, at least according to the latest data. New measurements reveal that the gas giant is slightly narrower at the equator and flatter at the poles than previously believed. For decades, scientists relied on measurements from NASA’s Voyager and Pioneer spacecraft to
A recent example was published in 2025 by researchers at the European X-Ray Free-Electron Laser Facility near Hamburg, among other institutions. They cooled iodopyridine, an organic molecule consisting of 11 atoms, almost to absolute zero and hammered it with a laser pulse to break its atomic bonds. The team found that the motions of the
