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.”
While wearing a mask is an effortless way to curb the transmission of COVID-19, face coverings have become extremely politicized in the U.S. during the pandemic. Continue reading New Study Links Sociopathic Traits to People Who Are Anti-Mask or Don’t Practice Social Distancing
Neil Pederson’s introduction to tree rings came from a “sweet and kindly” college instructor, who nevertheless was “one of the most boring professors I’d ever experienced,” Pederson said. “I swore tree rings off then and there.” But they kept coming back to haunt him.

The Guardian reports today that Cambridge University researcher Aleksandr Kogan’s relationship with Facebook wasn’t limited to his now infamous “thisisyourdigitallife” app. He had actually also received an additional sizable chunk of data from Facebook that he used for a research paper published in 2015. This dataset, however, differs quite a bit from that collected through Kogan’s personality app. While large in volume, this other set was anonymized and aggregated with no personally identifiable information included. As the 2015 research paper states, the data included “every friendship made on Facebook in 2011 in every country in the world at the national aggregate level,” which summed up to over 57 billion friendships.

In a new study published today in Science Advances, researchers present a 3D-printable ink that contains bacteria and they say that depending on what species of bacteria it holds, the ink stands to have a number of useful applications. “Printing using bacteria-containing hydrogels has enormous potential, as there is such a wide range of useful bacteria out there,” Patrick Rühs, an author of the study, said in a statement.
