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 […]

Tomato lovers have long known that the red fruit sold by supermarkets tastes like cardboard. A new study has found why: A genetic mutation that gives commercially produced tomatoes their uniform color also prevents the production of sugars and carotenoids that give a proper tomato its taste and health benefits. The mutation “is in literally 100 percent of modern breeds […]

The rover Opportunity has been roaming over the planet Mars since January 2004 and traveled over 28 miles. It has sent back 225,000 photos of the planets surface. The information from the rover has told us that the winter is twice as long as Earth’s winters. Since it is longer than Earths winters the scientists didn’t expect the rover to […]

Having a sense of purpose may add years to your life—and the benefit can be realized throughout adulthood. That’s the conclusion of a long-term study that tracked the physical and mental health of more than 6,100 Americans aged 20 to 75. Previous research has shown purposefulness to be one of the strongest predictors of longevity, but this is the first […]

Anatoli Brouchkov, a scientist whose curiosity and thirst for knowledge drove him to go beyond the standard protocol of his experimentation by injecting himself with an ancient “Eternal Life” bacteria. In 2009, a 3.5-million-year-old bacteria strain called Bacillus F was discovered deep in the permafrost of Siberia’s Sakha Republic. Scientists later found that mice and fruit flies exposed to the bacteria seemed to […]

The evidence for a new geological epoch which marks the impact of human activity on Earth is now overwhelming according to a recent paper by an international group of geo-scientists. The Anthropocene, which is argued to start in the mid-20th Century, is marked by the spread of materials such as aluminum, concrete, plastic, fly ash and fallout from nuclear testing […]

Researchers from the Centers for Disease Control and Prevention (CDC) have found that antibiotic resistance has risen to dangerous levels. If drastic action is not taken soon it will become a bigger killer than cancer by the year 2050. The report shows that at least 2 million people in the US are infected each year with germs that are resistant […]

For the first time, a mission designed to set its eyes on black holes and other objects far from our solar system has turned its gaze back closer to home, capturing images of our sun. NASA’s Nuclear Spectroscopic Telescope Array, or NuSTAR, has taken its first picture of the sun, producing the most sensitive solar portrait ever taken in high-energy […]

People always wonder how the moon was made. The birth of the planets 4.5 billion years ago was extremely violent. They grew to full size by absorbing rival planet embryos in a series of titanic collisions—one of which probably gave Earth its moon (below). The moon’s large size, low density, and other features suggest that it emerged from an explosion […]
