For the first time ever after an unprecendented experiment, scientists have created embryos that are a mix of both human and monkey cells, NPR reports.
Researchers have demonstrated just how easy it is to trick the mind into remembering something that didn’t happen. They also used two very simple techniques to reverse those false memories, in a feat that paves the way for a deeper understanding of how memory works.
They’re calling it a “zombie gene.”
A new study published in Scientific Reports challenges the widespread belief that brain activity comes to a halt immediately at death or shortly after. Researchers at the University of Illinois Chicago found that glial cells not only come alive, but also increase in size and grow arm-like appendages hours after a person dies. Study author Jeffrey Loeb, head of neurology and rehabilitation at the UIC’s College of Medicine, said the findings weren’t “too surprising” as the glial cells are inflammatory “and their job is to clean things up after brain injuries like oxygen deprivation or stroke.”
Einstein’s theory of general relativity puts a speed limit on all matter in the universe, creating a barrier preventing acceleration from below to above the speed of light.
However, an independent group of scientists, inventors, and engineers called Applied Physics recently proposed the first model for a physical warp drive, according to a recent study published in the peer-reviewed journal Classical and Quantum Gravity.
The most distant Solar System object, Farout, has lost its crown after just two years. As Inverse reports, astronomers have confirmed that the planetoid Farfarout is now the farthest known Solar System object. It’s currently 132AU, or about 12.3 billion miles from the Sun (Farout is ‘just’ 120AU away), and its elongated orbit will take it 175AU away. For context, Pluto is 34AU from our host star — Farfarout reaches over five times that distance, and takes about 1,000 years to complete an orbit.
Scientists assembled by the World Health Organization to investigate the origins of the covid-19 pandemic have announced their early findings. They concluded that the first known cases traced to a seafood market in Wuhan, China in December 2019 likely don’t represent the original source of the outbreak. At the same time, they considered the possibility of a lab accident causing the pandemic “extremely unlikely,” and speculated that the virus wasn’t circulating locally in people for very long before the first cases were discovered.
