Global warming hits plateau. . . What does that mean for the threat of catastrophic climate change? Why has the warming trend slowed? Climatologists aren’t sure. What they do know is that the average air temperatures at the earth’s surface have risen only about 0.2 degrees Fahrenheit since 1998—the hottest year of the 20th century—even as humanity has continued 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 […]

If you’re worried about infertility, don’t try to Google the term with a computer on your lap, says the London Telegraph. A new experiment suggests that radiation from a single Wi-Fi-enabled laptop may be strong enough to cause cell damage in sperm. Argentine researchers took samples of ejaculated semen and left them directly under a computer—simulating holding a laptop directly […]

Only 1 in 10,000 people have absolute or “perfect” pitch, the ability to hear a tone and tell what note it is. This unusual ability is acquired early in life, typically learned during training at about four to six years of age, and there are no records of adults acquiring the ability. But a new study shows that people who […]

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 […]

For the first time, scientists have caught a glimpse of a black hole ejecting a hot “flare” of matter after devouring a star the size of our sun. The discovery was made thanks to the quick action of of scientists from John Hopkins University, who worked in conjunction with a team from the University of Oxford. Hubble fellow Sjoert van […]

Karachi, Pakistan Nuclear plants at risk: Pakistani activists are seeking to block the construction of two nuclear power plants in an earthquake-prone, coastal area that is vulnerable to tsunamis. The Chinese are building the two reactors—using an experimental design—less than 20 miles from the sprawling city of Karachi, where 20 million people would be at risk should a reactor meltdown […]

NASA has initiated the DART mission, short for Double Asteroid Redirection Test. It was launched from Vandenberg Space Force Base, California to study the effects of asteroid deflection as a method to save the Earth from future devastating collisions by asteroids. The big question…. If an asteroid is pummeling towards Earth, can humanity be saved with a simple nudge? NASA […]

With temperatures in excess of 800 F, Mercury is one of the last places in the solar system you’d expect to find ice. But when NASA’s Messenger spacecraft transmitted its first optical images of the closest planets to the sun, that’s exactly what scientists discovered. Mercury sits about 36 million miles from the sun, which is roughly 57 million miles […]
