3D-printed generator allows you to generate electricity from snowfall
People can now tap snowfall for electricity, thanks to triboelectric nanogenerators that collect electrical energy from innocuous activities like footsteps and raindrops. The new energy harvester, developed by the University of California, Los Angeles (UCLA), is not only inexpensive but light as well – matching the thinness and flexibility of a plastic sheet. “The device can work […]

Which brain cells are active during deep sleep – and how do they affect memory formation?
There are neurons in the brain that activate during deep sleep to create memories. A new animal study showed that these brain cells might be the same as the ones responsible for investigating new objects. The experiment tracked the activity of single cells deep in the brains of both male and female mice as they […]

Scientists thought they knew volcanoes – until they looked under Bermuda
The Bermuda Islands sit atop evidence of a new process of volcanic formation. Researchers have discovered that molten material from the Earth’s mantle transition zone might filter toward the surface and form a volcano. Experts know of two methods of volcanic formation. One of the processes takes place when tectonic plates crash together. The other process involves […]

Advancing detection and diagnosis: Scientists enable 3D printers to print glass using material called chalcogenide glass
Additive manufacturing systems have added another challenging material to the list of things they may print on the fly. Canadian researchers demonstrated the capability to print out chalcogenide glass with a modified 3D printer. Chalcogenide glass is a type of covalently bonded glass that contains certain chemicals called “chalcogens.” It sees extensive use in optical […]

Mesmerized by the ocean? To understand why the moon is where it is, start with Earth’s tides
As far as the human race remembers, the moon has always been there. But how did it get up there in the first place – and what keeps it revolving around Earth? By firing lasers at artificial mirrors deployed on the moon, researchers have learned that Earth’s satellite is drifting away at the rate of […]

Cars running on “clean” hydrogen one step closer – world’s fastest hydrogen sensor developed
The safe and effective use of flammable hydrogen gas as a source of energy depends on the capabilities of the sensor system. In response, Swedish researchers has come up with hydrogen sensors that run fast enough to hit the performance targets for hydrogen-powered vehicles of the future. Their optical nanosensor fits within a plastic-based capsule. […]

Men and women are different, even when drunk: Research says men’s brains are more affected than women
Drinking excessive amounts of alcohol is not conducive to health, but it affects men differently than women. A recent study showed that the brain regions associated with emotions, memory, and social behavior displayed diminished activity in alcoholic men than in their female counterparts. Researchers reported that alcoholism impaired the function of the amygdala, hippocampus, and other limbic […]

What happens when herpes viruses merge? For one, a supervirus
Experts have known that the herpes simplex viruses (HSV) responsible for oral and genital infections were capable of mixing their genetic material. But a recent study by the University of Washington (UW) warns that these pathogens recombine more often than predicted. The HSV-1 virus is classically responsible for oral herpes. Meanwhile, HSV-2 triggers genital herpes. They share the […]

Swiss startup invents higher-performance electric car battery that can leave Tesla batteries in the dust
A startup in the tiny mountainous country of Switzerland promises to deliver what electric car giant Tesla Motors has failed to pull off. Its new lithium-ion battery is said to store and produce far more power for vehicles than existing designs. Swiss company Innolith claims that an electric vehicle equipped with its lithium battery would […]

Study: “Needles” could explain why lightning strikes twice
Yes, lightning may strike the same place twice. Dutch researchers have identified a new characteristic in the atmospheric discharge that may account for that ability to hit a location more than once. Thanks to the Low Frequency Array (LOFAR) radio telescope, the researchers got a very close look at the unseen details of lightning strikes […]
