Researchers Discover Some Brain Cells Come Alive and Grow Hours After Death

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.”

DRINKING TWO OR MORE DIET SODAS A DAY INCREASES CHANCES OF HEART ATTACKS AND STROKES, SAYS MAJOR NEW STUDY

According to a massive study from the American Heart Association and American Stroke Association, diet sodas and drinks containing artificial sweeteners are even worse for your health than you may have imagined, and can increase the likelihood of heart attacks, strokes, dementia, and diabetes.

Facebook gave researcher anonymized data on 57 billion friendships

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.

Researchers use CRISPR to detect HPV and Zika

Science published three studies today that all demonstrate new uses for CRISPR. The gene editing technology is typically thought of for its potential use in treating diseases like HIV, ALS and Huntington’s disease, but researchers are showing that applications of CRISPR don’t stop there.

3D-printed bacteria ink could be used to treat burns

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.
