A mind-controlled robotic glove under development by Washington University scientists could give hope to those whose hands have become paralyzed due to a stroke. 

In the journal Stroke, researchers reported some success with using the device, called the Ipsihand, to help stroke patients regain the ability to grasp objects. A  group of 10 patients wore the robotic exoskeleton over the hand, wirelessly connected to a cap fastened to the head that reads brain signals that tell the hand to open and close.

One morning at the Jackie Joyner-Kersee Center in East St. Louis, an unusual guest arrived to greet more than a dozen preschoolers, who gathered on a ketchup-colored mat, surrounded by cubby shelves, Clifford books and crayon drawings.

The visitor, a white robot with blue patches of armor on its head and joints, stood about 2 feet tall. It had arms and legs, like a person, but its plastic face had no expression.

Inside a huge warehouse at Boeing’s headquarters in St. Charles, a table-shaped drone rose from the middle of the floor.

As intern Edwin Mercado-Colon sat at a computer typing commands, the drone began to move around the room and an unmanned vehicle automatically followed.  But Mercado-Colon wasn’t using a controller to direct the drone. Instead, he picked a destination for the drone without telling it how to get there.

“He’s picking a spot in the lab to fly to,” said Mike Abraham, manager of Boeing’s Collaborative Autonomous Systems Laboratory. “That command goes to the vehicle. The vehicle knows where it is because of the motion capture system. It’s determining how to get to the next point, on its own.”

Developing unmanned vehicles that can work together on their own represents the latest in drone technology, a global industry that analysts predict could be worth $127 billion by 2020.

The Curiosity rover is cruising toward a specific set of sand dunes on Mars millions of miles across the universe. The St. Louis Science Center is trying to bring that science down to Earth.

A new exhibit aims to explain both the science and the thought process behind the Curiosity Mars rover, according to Paul Freiling, director of engineering and technology education at the center. For him, the scope of Curiosity’s responsibilities illustrate how problem-solving in space is the productive of cooperative minds.

Washington University is now home to one of the largest zebrafish research facilities in the world.

The one-inch long, striped tropical fish serve as models for studying human development and disease, from birth defects to heart disease to cancer.
