An ancient megastructure called a

It’s hard to imagine constructing a building without a detailed plan, but when exactly did humans first start doing that? Archeologists have discovered the oldest known blueprints, with a 9,000-year-old rock carving in Jordan depicting a to-scale plan for a nearby megastructure.

Electrical stimulation heals diabetic wounds three times faster

Posted on by

In diabetics, wounds tend to progress quickly and heal slowly. Researchers have developed a method that uses electricity to heal diabetic wounds three times faster and offers great potential for treating those with diseases that lead to reduced wound h… Continue reading Electrical stimulation heals diabetic wounds three times faster→

Artificial muscles made of human proteins make for better implants

Posted on by

Researchers have developed a new type of artificial muscle that’s entirely made out of natural proteins. Responding to changes in its environment allows the muscle to flex on demand, which could make it useful for implants, prosthetics or robotics.Cont… Continue reading Artificial muscles made of human proteins make for better implants→

Revolutionary technique produces injection-molded glass objects

Posted on by

Plastic is a lot easier to work with than glass, which is one of the reasons it’s used so much more often. That may be about to change, though, thanks to a new process that allows glass to be injection-molded – just like plastic.Continue ReadingCategor… Continue reading Revolutionary technique produces injection-molded glass objects→

Electrically charged paper goes from firm to soft at flick of a switch

Posted on by

Taking inspiration from the way sea cucumbers can strengthen their exterior when in danger, scientists in Germany have developed a novel wafer-thin paper material that can transition from firm to soft via an electrical switch. The researchers envisage … Continue reading Electrically charged paper goes from firm to soft at flick of a switch→

Targeting brain cells with light halts epileptic activity in mice

Posted on by

One of the ways scientists hope to deliver more precise and effective treatments for conditions afflicting the brain is by using light to target cells, which can be made to respond to this stimuli through light-sensitive proteins and molecules. A resea… Continue reading Targeting brain cells with light halts epileptic activity in mice→

Dinosaur-killing asteroid struck at “deadliest possible angle”

Posted on by

It turns out that the dinosaurs had far worse luck than we thought. While a gigantic asteroid slamming into the Earth is never going to be a sign of good luck, a new study has shown that the space rock hit the planet at the deadliest possible angle, ma… Continue reading Dinosaur-killing asteroid struck at “deadliest possible angle”→
