Crystal gems found in extreme igneous rocks could form within hours, study suggests
Researchers from Rice University in Texas and the University of California, Riverside have found that gems can grow within hours inside extreme igneous rocks called pegmatites, instead of the thousands of years they usually take to form. In a study published in the journal Nature, the researchers described how they examined sample crystals from a pegmatite mine in Southern California. Using […]

Researchers develop a rewritable paper coating that encrypts sensitive data using only WATER
Chinese researchers have developed a special kind of paper coating that allows invisible messages to be written on it with water. The messages are visible only under ultraviolet (UV) light and can be erased by heating the paper. In a paper published in the journal Matter, the researchers described how invisible messages can be printed […]

A truly versatile crop: HEMP batteries can be a more powerful alternative to graphene or lithium batteries
Hemp, the non-psychoactive variety of the Cannabis sativa plant, may soon power a smart device near you. Researchers say that not only can hemp be used to power devices, but it may also be a more powerful alternative to lithium and graphene batteries. Hemp-based nanosheet better than graphene In a study published in the journal ACS Nano, Canadian researchers […]

Scientists discover protein that allows soil bacteria to generate electricity in microbial fuel cells
Bacterial cells are only about one-tenth the size of human cells. Despite being considerably smaller, bacteria have more complex respiratory mechanisms than humans. And while higher animals produce carbon dioxide when they breathe, some bacteria can generate an electric current when they “exhale.” In a new study published in the journal Nature Chemical Biology, researchers from Yale […]

Cryopreserved avocados may be sent to outer space
Astronauts may never have to miss out on avocados during a space voyage, thanks to a group of researchers who developed a cryopreservation method for the fruit. The team froze avocado shoots in cryotubes and revived them later to be regrown into a healthy plant. After trying out different techniques and avocado varieties, they said that the series of experiments was an overall […]

Scientists can now implant “false memories” into animal brains
The idea of scientists implanting “false” memories might seem like a scene straight out of a science-fiction book. But as it turns out, it isn’t as far-fetched as it seems. In a recent study, neuroscientists at the Hospital for Sick Children in Toronto succeeded in manipulating mice brains into retaining memories that never happened to them […]

Researchers examine how pink sea urchins sharpen their teeth to develop self-sharpening tools
Aside from their fearsome array of spines, sea urchins have another evolutionary edge over other sea creatures: self-sharpening teeth. According to researchers from Northwestern University, the spiny invertebrates, unlike other animals whose teeth are built to resist constant wear and tear, have teeth engineered to chip and weather in such a way that they maintain their sharp […]

Researchers develop device that can better detect signs of extraterrestrial life
A group of researchers has developed a fully automated device that could better detect signs of alien life. Astronomers have been trying to look for evidence of extraterrestrial life for decades. They typically use detection methods that look for carbon, which is an important component of organic compounds. But current technologies are limited; some devices can’t […]

New theory suggests how magnetars, a type of neutron star, can crack themselves open and send gamma-ray flares to Earth
Earth was pummeled by three separate series of intense gamma-ray flares in the last 40 years. While scientists agree that magnetars, a type of neutron star, were behind the flares, the mechanism that unleashed those waves of energy remains unknown. A recent study offers a compelling theory to what that mechanism is. Researchers from the University of […]

Forgotten dreams: REM sleep helps prevent information overload, explain scientists
Dreams are quickly forgotten the moment people wake up. This is likely due to a group of neurons that gets activated during rapid eye movement (REM) sleep – the phase of mammalian slumber when most dreams are made. A recent study published in the journal Science examined the neurons that produce appetite and sleep hormones in mice. Japanese and American […]
