As the world’s largest land mammals, elephants should suffer one of the highest cancer rates—they simply have far more cells that could potentially mutate and become malignant. But new research reveals that elephants rarely get cancer—and the reason why may help in the search for human treatments. Only about 4.8 percent of elephants die from cancer, compared with up to […]

In 2015, scientists predicted that a massive solar eruption would hit Earth just before New Year’s Eve. It was expected to cause power fluctuations, radio blackouts and even affect GPS reception. There was a small chance it could make the Northern Lights visible in the San Francisco Bay Area. The National Oceanic and Atmospheric Administration predicted that the Aurora Borealis […]

Mystery crater: A 40-foot crater has appeared in the ground near Managua airport. Nicaraguan authorities said the hole was caused by a meteorite that broke off from the passing Pitbull, or 2014 RC, asteroid. But NASA officials said that was unlikely, because such a strike would have produced an enormous fireball streaking across the sky, yet nobody reported seeing anything […]

Supermassive black holes that have escaped their host galaxies may be wandering the universe alone. Intriguing new observations i by NASA’s Chandra X-ray telescope have | revealed what appears to be a supermassive | black hole being “kicked out of a galaxy at enormous speed,” Francesca Civano of the Harvard-Smithsonian Center for Astrophysics tells Space.com. Astronomers observed two distinct light […]

Mysterious radio signals from space have been known to repeat, but for the first time, researchers have noticed a pattern in a series of bursts coming from a single source half a billion light-years from Earth. Fast radio bursts, or FRBs, are millisecond-long bursts of radio waves in space. Individual radio bursts emit once and don’t repeat. But repeating fast […]

What is hail or a hailstone? Hail is a form of precipitation that occurs when updrafts in thunderstorms carry raindrops upward into extremely cold areas of the atmosphere where they freeze into balls of ice. Hail can damage aircraft, homes and cars, and can be deadly to livestock and people. How does hail form? Hailstones grow by colliding with supercooled […]

Why Ice Dropped 137 Meters Sounds Like a Laser If you drop a chunk of ice down a 137-meter-deep hole, you probably expect to hear a distant thud, crack, or splash when it reaches the bottom. What you probably don’t expect is something that sounds like it came straight out of Star Wars. Yet that’s exactly what can happen. Videos […]

Every week, more than 50 million Americans take acetaminophen, the active ingredient in Tylenol and many other popular painkillers, to ease their aches and pains. But a new study has revealed that the drug also dulls emotions—including happiness. Prior research showed that acetaminophen can help take the sting out of negative feelings like dread, but the new findings from Ohio […]

Researchers have identified a new mechanism that drives the development of form and structure, through the observation of artificial materials that shape-shift through a wide variety of forms which are as complex as those seen in nature. It’s curious to observe such life-like behavior in a non-living thing – in many cases, artificial objects can look more ‘alive’ than living […]
