Happy Earth Day! Neil deGrasse Tyson and comic co-host Chuck Nice are here to help you celebrate Earth Day 2020 by giving you a cosmic perspective. How did we come to have a cosmic perspective about humanity’s place in the universe? According to Neil, a lot of this new way of thinking can be traced […]

Vaccines are quite possibly the greatest thing that humans ever created. Vaccination has its roots in variolation, a technique developed by Asian physicians prior to the 1700s.

MIT’S new mini cheetah robot is the first four-legged robot to do a backflip. At only 20 pounds the limber quadruped can bend and swing its legs wide, enabling it to walk either right side up or upside down. The robot can also trot over uneven terrain about twice as fast as an average person’s […]

Having robots learn dexterous tasks requiring real-time hand-eye coordination is hard. Many tasks that we would consider simple, like hanging up a baseball cap on a rack, would be very challenging for most robot software. What’s more, for a robot to learn each new task, it typically takes significant amounts of engineering time to program […]

At MIT’s Media Lab, researchers are developing prosthetic limbs that users can control with their minds, making a robotic foot move as seamlessly as a biological one.

Meet the Guardian XO from Sarcos Robotics, the world’s first battery-powered robot that helps humans safely lift up to 200 pounds (90 kilograms) for eight hours a day, without strain or injury. It can make 100 pounds feel like it only weighs 5. Also recently Sarcos Robotics announced a partnership with Delta Airlines to use […]

Researchers find that a motorized device that attaches around the ankle and foot can drastically reduce the energy cost of running.

If you’re in the wilderness and have nothing, perhaps the most important thing you need is a sharp, durable edge. Humans are among the weakest species on the planet and tools are what help us compensate for that lack of strength. Dr. Bill Schindler, a professor of archeology and anthropology at Washington College, explains how […]

In paroxysmal nocturnal haemoglobinuria (PNH), the immune system mistakes red blood cells for dangerous invaders and attacks them. This life-threatening disease is triggered by a fault in the body’s blood-making machinery, and although therapies are available, researchers are still working on improving treatments.

New study also reveals ancient human ancestors enjoyed a long childhood.

Scientists and doctors have observed for thousands of years that some diseases, like polio and influenza, rise and fall with the seasons. But why? Ongoing research in animals and humans suggests a variety of causes, including changes in the environment (like pH, temperature, and humidity) and even seasonal and daily changes to our own immune […]
