• Stone Age To Bone Age?

  Archeologists know early humans used stone to make tools long before the time of Homo sapiens. But a new discovery out this week in Nature suggests early humans in eastern Africa were also using animal bones – one million years earlier than researchers previously thought. The finding suggests that these early humans were intentionally shaping animal materials – like elephant and hippopotamus bones – to make tools and that it could indicate advancements in early human cognition.

• Will Bark For Science

  On their second job ever, Collette Yee and her partner were assigned a difficult job: locate transient whale poop in the ocean before it sinks. Luckily, Collette was partnered with Jack, a blue healer mix trained to sniff out cryptic odors from things that conservation biologists have trouble collecting on their own. Producer Berly McCoy reports on Jack and the growing field of dog detection conservation that helps science by sniffing out everything from invasive crabs to diseased plants to endangered species.

• Reviving The Woolly Mammoth ... With Mice

  You've heard of the woolly mammoth. But have you heard of woolly mice? These critters were genetically modified by the Dallas-based biotech company Colossal Biosciences to have the same "woolly" and fat appearance as the ancient mammoths. The mice are a key step in the longer journey to de-extinct the woolly mammoth. NPR's Rob Stein takes us to the lab where it all happened.Interested in more biotech stories?

• What It's Like Taking Alzheimer's Drugs

  There are now two fully approved drugs on the market that can, sometimes, slow down the progression of Alzheimer's disease. Both have been shown to slow down the mental decline of Alzheimer's by more than 25%. But that's in a group of patients—an individual may do much better, or not be helped at all. NPR Science Correspondent Jon Hamilton has been talking to people who've taken these drugs. Today he has the story of two patients to receive them.Interested in more human health stories?

• When Batteries Get A Face Lift, So Do Renewables

  Batteries are everywhere. They're in our phones, our remote controls, smart-watches, electric cars and so much more. They could also be the solution to a problem that renewable energy companies have faced for years: How to store the mass amounts of energy they produce for later use. Some companies are using batteries to make renewable energy accessible 24/7. Today, we dig into how the technology is rapidly progressing with Cooper Katz McKim, a producer from fellow NPR podcast The Indicator from Planet Money. Listen to The Indicator's three-part battery series. Have questions about the future of technology? Contact us at [email protected].
