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 […]

Patients are getting larger and perhaps even dangerous doses of radiation from the growing number of advanced medical-imaging tests being ordered by doctors, a new study says. Researchers at the University of California, San Francisco, analyzed data from millions of patients who received medical treatment between 1996 and 2010. They found that the number of patients who underwent CT scans […]

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 […]

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 […]

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 […]

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 […]

When you’re angry, your face, head, and arms grow hot When you’re depressed, a cold numbness grips your head and arms. Love triggers a warm glow throughout your upper body, especially around your heart. Human emotions, a new study has found, are directly linked to sensations in specific body parts, and the map is largely the same across different cultures. […]

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 […]
