A team of researchers from the Institute of Advanced Materials, Nanjing University of Posts and Telecommunications in China, has created a rewriteable paper coating capable of encrypting secret information using invisible water-based ink.

The robot can reportedly carry soldiers' equipment, which according to researchers increases both soldier mobility and lethality.

The autonomous octocopter is reportedly capable of positioning a nail gun above a targeted nailing point, triggering the gun to insert the nail, and then moving on to the next point — all without human operators.

Engineers from the University of Virginia (UVA) School of Engineering, in collaboration with biologists from Harvard University, have developed what they are calling the first-ever robotic fish to mirror the movements and speed of a live yellowfin tuna.

The researchers noted that the mosquitofish with greater exposure to the aggressive robotic fish weighed less, suggesting that their energy reserves were depleted, and thus less likely to devote energy to reproduction.

According to the researchers, this strengthens the wearer’s stroke-affected leg, improving gait proportionality once the shoe is taken off.

Researchers at the University of Oxford have devised a new biomarker using artificial intelligence (AI) that can reportedly identify people at significant risk of experiencing a fatal heart attack roughly five years before it happens.

The water and calcium carbide react, producing acetylene gas, which is then ignited for thrust.

An algorithm translates user intention into finger movement on the prosthetic hand.

The United States Navy has successfully tested a system that relies on autonomous robots to detect, identify and destroy sea mines.
