Inspired by gecko feet, scientists invent super-adhesive material

For years, biologists have been amazed by the power of gecko feet, which let these 5-ounce lizards produce an adhesive force roughly equivalent to carrying nine pounds up a wall without slipping. Now, a team of polymer scientists ...

Why we walk on our heels instead of our toes

James Webber took up barefoot running 12 years ago. He needed to find a new passion after deciding his planned career in computer-aided drafting wasn't a good fit. Eventually, his shoeless feet led him to the University of ...

Five-meter sea creature found off California coast

A marine science instructor snorkeling off the Southern California coast spotted something out of a fantasy novel: the silvery carcass of an 18-foot-long (5-meter-long), serpent-like oarfish.

Global sea level could rise 15 meters by 2300, study says

Global average sea-level could rise by nearly 8 feet (2.5 meters) by 2100 and 50 feet (15 meters) by 2300 if greenhouse gas emissions remain high and humanity proves unlucky, according to a review of sea-level change and ...

SpaceX's 10-story reuseable Grasshopper rocket takes a bigger hop

SpaceX is developing the "Grasshopper" reusable vertical takeoff, vertical landing rocket. Back in September, the 32-meter- (106-ft-) tall Grasshopper made a tiny hop – barely lifting off the pad just to test-fire its engines. ...

From nature, robots

(PhysOrg.com) -- To a robot designer like Sangbae Kim, the animal kingdom is full of inspiration. "I always look at animals and ask why they are the way they are," says Kim, an assistant professor of mechanical engineering ...

In the war against dust, a new tool inspired by geckos

Micrometric and sub-micrometric contaminant particles—what most of us call "dust"—can cause big problems for art conservators, the electronics industry, aerospace engineers, and others. These nanoparticles can prevent ...

Feet may be the key to hand evolution

(PhysOrg.com) -- Scientists in Canada have used a mathematical model to simulate the evolution from an ape-like hand to the modern-day human hand, and discovered that changes in our fingers and hands developed in parallel ...
