Team develops fast, cheap method to make supercapacitor electrodes

UW team develops fast, cheap method to make supercapacitor electrodes for electric cars, high-powered lasers. Supercapacitors are an aptly named type of device that can store and deliver energy faster than conventional batteries. They are in high demand for applications including electric cars, wireless telecommunications and high-powered lasers. But to realize these applications, supercapacitors need better electrodes, which connect the ...

The glass transition caught in the act

We learn in school that matter comes in three states: solid, liquid and gas. A bored and clever student (we’ve all met one) then sometimes asks whether glass is a solid or a liquid. The student has a point. Glasses are weird “solid liquids” that are cooled so fast their atoms or molecules jammed before organizing themselves in the regular ...

Empowering robots for ethical behavior

Scientists at the University of Hertfordshire in the UK have developed a concept called Empowerment to help robots to protect and serve humans, while keeping themselves safe. Robots are becoming more common in our homes and workplaces and this looks set to continue. Many robots will have to interact with humans in unpredictable situations. For example, self-driving cars need to ...

Hubble Spots Barred Spiral Galaxy Lynx

Discovered by British astronomer William Herschel over 200 years ago, NGC 2500 lies about 30 million light-years away in the northern constellation of Lynx. The NGC 2500 is a particular kind of spiral galaxy known as a barred spiral, its wispy arms swirling out from a bright, elongated core. Barred spirals are actually more common than was once thought. Around two-thirds ...

Using Einstein’s Theory, Brightest Galaxy 10000 Million Light Years Away Discovered

Using Albert Einstein’s gravitational lensing theory, scientists have discovered a galaxy at about 10,000 million light years away but thousand times brighter than the nearest Milky Way. Anastasio Diaz-Sanches from Polytechnic University of Cartagena (UPCT) in Spain used gravitational lensing phenomenon found by Einstein to magnify the apparent image of the original object. “Thanks to the gravitational lens” explained Sánchez, ...

No Life Possible Due to UV Radiation on Mars, Finds New Study

When NASA scientists declared that finding alien organism on Mars surface is a possibility soon, they were not sure about the perchlorate effect. Now that new research has found that the bacteria exposed to UV-activated perchlorate were killed within minutes, may change their perception about the possibility of life in the form of any organism, forget about the bacteria. Perchlorate ...

Wiped out Dinosaurs Gave New Life to Frogs: Study

The dinosaurs wiped out from Earth gave rise to most of the frogs alive today. A new study by Chinese and American biologists shows that if the calamity had not wiped the planet clean of most terrestrial life 66 million years ago, 88 percent of today’s frog species wouldn’t be here. Nearly nine out of 10 species of frog today ...
