The Amazon rainforest is in flux, thanks to agricultural expansion and climate change. In other words, humans have “become important agents of disturbance in the Amazon Basin,” as an international consortium of scientists wrote in a review of the state of the science on the world’s largest rainforest published in the journal Nature. The dry…
The modern meltdown of the Antarctic Ice Sheet mirrors the frozen continent’s big thaw after the last ice age ended 20,000 years ago, a new study finds. New ice core records from West Antarctica show the huge ice sheet started heating up about 20,000 to 22,000 years ago, 2,000 to 4,000 years earlier than previously…
A trove of sophisticated stone tools recently dug up from a South African cliff suggests early modern humans developed complex cognitive ability anywhere from 6,000 to 10,000 years earlier than many scientists believe. In a study published in the journal Nature, researchers said they had unearthed a large number of small stone blades going back…
If our universe slammed into a neighboring one during a growth spurt in its first second, the collision would have left a mark. And Matthew Kleban thinks he sees it in the most detailed snapshot yet taken of the dawn of the universe. The satellite image, released by astronomers in March, confirmed what an earlier…
The arguments against an electric car are growing fewer. A vehicle in development by ECOmove – a consortium of Danish car builders – has unveiled a car that can travel 500 miles without refueling. Once a sticking point for electric vehicles, distance could be ticked off the list of grievances the driving populace has with…
A 2011 report about STEM workforce needs from the Center on Education and the Workforce at Georgetown University indicates that by 2018, 92% of STEM workers will need post-secondary education. Of that total, around 65% will need a Bachelor’s degree or higher, while 35% will be comprised of those with sub-baccalaureate training. The breakdown in…
