Cold temperature lipid created by the body may lower blood sugar, report scientists
A recent study published in the journal Cell Metabolism found that 12-HEPE, a lipid produced by the body in response to cold temperatures, may help reduce blood sugar levels. Researchers from Brazil, the U.S. and Germany conducted a series of experiments on mice and humans and found that it could help shuttle glucose into tissues and improve glucose tolerance […]

New super-enzyme “eats” plastic six times faster
Scientists have created a super-enzyme that can degrade plastic bottles up to six times faster than a previously discovered plastic-eating enzyme. The synergistic enzyme “cocktail” combines PETase and MHETase. These enzymes are produced by Ideonella sakaiensis, a bacterium that has evolved the ability to eat polyethylene terephthalate (PET), a strong, synthetic fiber used in creating plastic […]

Astronomers unveil first direct image of young exoplanet just 63 light-years away
An international team of researchers has recently obtained the first direct image of the exoplanet Beta Pictoris c (B Pic c), confirming its existence since its indirect discovery in 2019. The “baby” exoplanet, which is estimated to be around 18 million years old, is the second planet known to orbit the star Beta Pictoris. The star […]

Skulls from a cave in Spain suggest Stone Age people may have performed brain surgery, practiced human sacrifice
A pair of Stone Age skulls unearthed in the Dehesilla Cave in Spain shows signs of a halted brain surgery and possible human sacrifice, according to a study published in the journal PLOS ONE. An international team of researchers said that the skulls, which date back to 4,800 to 4,500 B.C., may have belonged to a man and a […]

Physicists build “energy harvesting” circuit from graphene
A team of physicists from the University of Arkansas (U of A) has successfully developed graphene-based circuits capable of providing nearly limitless power for small devices. Described in a paper published in the journal Physical Review E, the findings prove a theory the physicists developed at the U of A three yeas ago. This theory stated that freestanding graphene […]

Archaeologists unearth Medieval poop that might hint at what a healthy gut microbiome looks like
Medieval fecal samples from Israel and Latvia could provide crucial insights into how gut diseases developed, suggests a recent study published in the journal Philosophical Transactions of the Royal Society B. The samples were recovered from two latrines located in the capital cities of Jerusalem and Riga, which date back to between the 14th and 15th centuries. […]

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 […]
