The Download: What tomorrow holds for today’s babies, and replacing the brain

Drones have been a mainstay technology among militaries, hobbyists, and first responders alike for more than a decade. No longer limited to small quadcopters with insufficient battery life, drones are aiding search and rescue efforts, reshaping wars in Ukraine and Gaza, and delivering time-sensitive packages of medical supplies. And billions of dollars are being plowed into building the next generation of fully autonomous systems. 

These developments raise a number of questions: Are drones safe enough to be flown in dense neighborhoods and cities? Is it a violation of people’s privacy for police to fly drones overhead at an event or protest? Who decides what level of drone autonomy is acceptable in a war zone?

Those questions are no longer hypothetical. Advancements in drone technology and sensors, falling prices, and easing regulations are making drones cheaper, faster, and more capable than ever. Here’s a look at four of the biggest changes coming to drone technology in the near future.

Aging hits us in our 40s and 60s. But well-being doesn’t have to fall off a cliff.

You might feel like you’re on a slow, gradual decline, but, at the molecular level, you’re likely to be hit by two waves of changes, according to researchers at Stanford University. The first one comes in your 40s. Eek.
