Snarling Head of Giant 40,000-yr-old Wolf Found with Hair and Brain Intact
Posted by Heather Blevins in category: neuroscience
An amazingly well-preserved head of an ancient wolf has been identified. A Russian man named Pavel Efimov was out for a walk last summer when he came across a startling sight. Along the shore of the Tirekhtyakh River in Siberiaâs Yakutia, he spotted a huge severed animal head. On closer inspection, it looked like it could be a wolfâwith a full head of hair. Its long sharp teeth were intact, making the beast look as if it were still snarling.
The scientists that Efimov carried the head to ran many tests and have just concluded that it was indeed a wolf and estimated the animal was about 40,000 years old. The head alone measured a whopping 16 inches in length. And, yes, the brain was intact.

Black hole âhairâ could be detected using ripples in space-time
Posted by Malak Trabelsi Loeb in categories: cosmology, physics
Black holes are celestial objects with such massive gravity that not even light can escape their clutches once it crosses the event horizon, or point-of-no-return. The event horizons of black holes lock secrets deep within them â secrets that could completely revolutionize our understanding of physics.
Unfortunately, for decades many scientists thought whatever information falls into a black hole might be lost forever. But new research suggests that ripples in space-time, or gravitational waves may carry a faint whisper of this hidden information by revealing the presence of wispy âhairsâ on a black holeâs surface.
Hair may record the information swallowed by the gravitational monsters.

An asteroid the size of a high-rise will fly near Earth on September 1
Posted by Quinn Sena in categories: asteroid/comet impacts, existential risks
It is reported that the dimensions of the celestial body are from 22 to 49 meters. According to the space agency, at the minimum distance to the planet â about 120 thousand kilometers â the asteroid will come up at 19.12 Moscow time. The asteroid is moving at 8.16 kilometers per second.
Note that the celestial body was discovered on March 2, 2011. It belongs to the group of âApolloâ, that is, asteroids, whose flight paths cross the Earthâs orbit.

Scientists Use Fruit Peel to Turn Old Lithium-Ion Batteries Into New
Posted by Quinn Sena in categories: economics, food
Scientists led by Nanyang Technological University, Singapore (NTU Singapore) have developed a novel method of using fruit peel waste to extract and reuse precious metals from spent lithium-ion batteries in order to create new batteries.
The team demonstrated their concept using orange peel, which recovered precious metals from battery waste efficiently. They then made functional batteries from these recovered metals, creating minimal waste in the process.
The scientists say that their waste-to-resource approach tackles both food waste and electronics waste, supporting the development of a circular economy with zero waste, in which resources are kept in use for as long as possible. An estimated 1.3 billion tonnes of food waste and 50 million tonnes of e-waste are generated globally each year.

Is water wet? â The Answer Wall.
I provided this answer last week: Wetness is a perception, not an objective fact, and perceptual clues for wetness are actually not so straightforward, as you can see in this physiology article: bit.ly/wetness-perception. So, is water wet? Sorta maybe.
