Rare 85,000-year-old Finger Bone Complicates Our Understanding of African Migration

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 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.

What happens if Earth gets 2°C warmer?

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.
