Neanderthals Were Just As Violent As Early Humans  

Is it time to put the stereotype of the violent and brutish Neanderthal to rest? New research paints a different picture of the ancient hominin — one that looks similar to Homo sapiens. Researchers previously thought that Neanderthal lives were far more nasty, brutish and short than ancient H. sapiens, based mainly on studies looking at levels of injury among both groups. Now, however, in a much more comprehensive look, a team of University of Tübingen (UIT) researchers found that ...

When It Rains in the Atacama Desert, the Microbes There Die  

Exterminating Rains The rain fell in the Atacama Desert in Chile for the first time in hundreds of years, and it caused a mass extinction. It might seem natural to think that such rains would be followed by blooming flowers and new life. But, an international team of planetary astrobiologists found, this precipitation killed most of the microbial life in the region. "When the rains came to the Atacama, we were hoping for majestic blooms and deserts springing to life. Instead, we lear...

Pluto's Strange Ridges Formed From Ancient Glaciers  

Scientists have traced strange landforms on Pluto back to their ancient glacial origins. A letter by SETI Institute scientist Oliver White and colleagues shows how ridged landforms on Pluto provide evidence for glaciers on the dwarf planet some 4 billion years ago. Their research targeted the landscape that borders the ice-covered impact basin Sputnik Planitia - the western portion of Pluto's "heart." It has noticeable ridges that can't be explained by any simple terrestrial or planetar...

The U.S. May Ban Kratom. But Are its Effects Deadly or Lifesaving?  

Across America, thousands of people are throwing away their prescription drugs and picking up kratom, a plant-based drug from Southeast Asia usually brewed as a tea. Within the leaves of this tropical tree are opioid-like compounds that users say provide pain and anxiety relief, and the ability to wean off street drugs like heroin. But some health organizations warn kratom can be addictive itself or even deadly. An estimated five million people use kratom regularly, according to the Amer
