For years, archaeologist Huw Groucutt and his team had driven one particular stretch of desert on their way to dig sites in Saudi Arabia. As they drove they caught glimpses of what looked like bones, emerging from the slowly eroding sand. Finally, in 2014, the team decided to explore the array of bones at Al Wusta. Within two years, amidst more than 800 fossilized animal bones and nearly 400 stone artifacts, they discovered something remarkable: the middle digit of a finger bone, from what appeared to be a modern human.

Stretching 3.5 million square miles across northern Africa, the vast sand dunes and rocky plateaus of the Sahara cover more ground than the continental United States. Now, a pair of scientists is making a provocative claim that the world’s largest desert has expanded 10 percent since the early 20th century, effectively adding another Texas-sized chunk. Continue reading What’s Going On With the Sahara Desert?
President Trump’s proposed 2019 budget calls for deep cuts to research, and while it is unlikely to gain traction in Congress, it is a troubling statement of the administration’s priorities. As Neil deGrasse Tyson tweeted, “The fastest way to Make a America Weak Again: Cut science funds to our agencies that support it.” Continue reading NASA almost never came to be. Its creation is a lesson in political power.
Scientists have known for some time that trees not only have a sex, but can sometimes switch between sexes. But they haven’t always known why. Now, as The Washington Post’s Amy Ellis Nutt reports, a new study suggests that for at least one species, the switch happens after injury.
If the world gets warmer by two degrees Celsius, we’re screwed. To prevent that, the United Nations signed the Paris Agreement, an international treaty designed to keep the average global temperature “well below 2°C above pre-industrial levels”…A.K.A. what the Earth was like before factories started spewing greenhouse gases into the air.
Daimler AG, the automaker which produces the Mercedes-Benz line of luxury vehicles, is facing growing scrutiny after US investigators reportedly found that it installed software to cheat diesel emissions tests on cars, Bloomberg and Reuters reported.
On the rocky shores of a windswept island just west of Ireland, the 620-ton boulder looks almost at home. But careful analysis of its position over the last few years has revealed something odd: between the summers of 2013 and 2014, the boulder shifted a couple meters toward the sea. That discovery is causing scientists to rethink what they know about the impacts of powerful storms.
