Spending evenings in front of a glowing computer, TV, or cellphone screen can put you at risk of depression, Science News reports. Nighttime exposure to light from gadgets has already been shown to contribute to insomnia, cancer, obesity, and diabetes. Now, a new study shows that screen glow can cause mood-related changes in the brain. For weeks, researchers exposed hamsters […]

Scientists have long puzzled over the origins of Earth’s vast oceans. Now, new data from the Rosetta spacecraft appear to have crossed one potential source off the list: comets. Rosetta has been in close orbit around comet 67P/Churyumov- Gerasimenko since August, analyzing its chemical makeup. Among the mission’s goals was to determine if the water locked in the comet’s icy […]

Scientists have taken the first steps toward writing the blueprint of life in an alphabet unknown to nature, they reported online in the journal Nature. Until now, biologists have used the same base molecules when synthesizing DNA. It has been recently announced that scientists have not only created two new bases, but also inserted them into a single-cell organism and […]

A new study has found the strongest link yet between air pollution and autism, which experts now say affects one in 50 U.S. schoolchildren. Pregnant women who lived in areas with high levels of diesel exhaust and airborne mercury were found to be twice as likely to have a child with autism as those living in places with the lowest […]

Thanks to the Hubble space telescope, it is nearly impossible to unsee the huge glimmering region on the surface of Uranus. The cause of this blatant smear on Uranus is caused by powerful bursts of solar wind. Streams of charged particles caught in powerful magnetic fields forced into the upper atmosphere of Uranus, where their interactions with gas particles, such […]

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 […]

“It has happened,” said Philip Bump. For the first time in human history, atmospheric carbon dioxide levels hit a daily average of 400 parts per million (ppm) last week. “There is now more carbon dioxide in the atmosphere than at any point since 3 million years ago.” Back then, global temperatures were about 7 degrees higher, the Arctic was ice-free, […]

When we see a magical light show from the sun it is called “stretched loops” that are visible when the sun is rotated showing its profile to the earth. These lights move along a magnetic line that shows us these yellow lights that are charged particles of ultraviolet light. In about 5 billion years the sun will shine its last […]

The average human being generates about eight watts of energy with each step, most of which is expended as vibration. It may not sound like much, but take the 30,000 or more people who pass through a major-city subway hub at rush hour, and suddenly you’ve got serious power. That’s usually a problem for architects and engineers, who have to […]

Researchers in Japan say they have found evidence that radiation from the March 2011 Fukushima Daiichi nuclear power plant accident has caused the mutation of dozens of butterflies. The mutant butterflies are assumed to be just one of many affected wildlife species. The mutant butterflies have been shown to have stunted wings, irregularly developed eyes, disfigured antennas and different color […]
