Study Revealed Both Humans and Climate Change Killed Off Ice Age Giants, But How?
Jun 20, 2016 03:55 AM EDT Patagonia in South America was once the home of Ice Age giants, like huge sloths, bears and saber-toothed cats. Suddenly, they all died at exactly the same time--around 12,300 years ago. A new study published in the journal Science Advances revealed that the species were killed off as a result of human activities and rapid climate change. Molecular biologist Alan Cooper of the University of Adelaide said his team discovered that human hunting drove a swift blow to t..>> view originalMost distant oxygen in ionized form detected in truly ancient galaxy
Signs of oxygen have been detected in a truly ancient galaxy SXDF-NB1006-2. This galaxy, which is one of the universe’s first galaxies, could help know the role of first stars in clearing the fog that once filled the universe. The ancient galaxy is located around 13.1 billion light-years from earth. When it comes to reionization, researchers do not have clear idea on the same, as what the first stars were like. Previous studies have explained that massive stars were majorly responsible for reio..>> view originalFather's Day: How Astronauts Celebrate in Space — and on Earth

The first time physicists announced that the Laser Interferometer Gravitational-wave Observatory (LIGO) had detected gravitational waves, on September 14, 2015, it was breaking news. The discovery coincided with the 100-year anniversary of Einstein's theory of General Relativity, which predicted the existence of gravitational waves. Last week's announcement that LIGO had detected a second round of gravitational waves proved that the first signal was not a fluke. The tremendous effort from thous..>> view originalNow, it is possible to track activities of terrorism groups like ISIS by applying algorithms
When it comes to analyzing terrorism, and terrorists and their activities, it seems algorithms involving laws of physics could come in handy as a researcher has shown that it is possible to track activities of terrorism groups like ISIS by applying algorithms. Researchers at University of Miami carried out a study using VKontakte, the largest online social networking service in Europe. The reason why researchers selected VKontakte for their study is that pro-ISIS groups on VK are able to surv..>> view originalThe summer solstice is Monday: 7 things to know about the longest day of the year
The summer solstice is upon us: Monday, June 20, will be the longest day of 2016 for anyone living north of the equator. If pagan rituals are your thing, this is probably a big moment for you. If not, the solstice is still pretty neat. This year’s even includes a "strawberry moon," the first time that’s happened in 70 years. Below is a short scientific guide to the longest day of the year (though not, as we’ll see, the longest day in Earth’s history — that happened back in1912). 1) Why do we ha..>> view originalChinese supercomputer tops list of world's fastest computers
