Judge Rules Cops can Search Through DNA Database GEDmatch

· · Link

A judge recently ruled that law enforcement have the ability to search through DNA database GEDmatch, overriding the choice of its over one million users.

In the wake of that attention-grabbing case, GEDmatch changed its policies in May 2018 to make it less easy for police to access their data. Users now have to opt in to having their data made available to police; information they upload is set to private by default. Rogers told the NYT that as of October, less than 15% of current users, 185,000 out of 1.3 million, have opted in to sharing their data with police.

Astronaut Twin Study Finds Space Travel Can Alter DNA

· · Cool Stuff Found

A new study based on astronauts Scott Kelly and Mark Kelly—identical twins—found that space travel can alter DNA, at least the way we’re doing space travel now. The study found that 7% of Scott Kelly’s DNA did not return to normal after a one-year mission in space. Gizmodo noted that the change is epigenetic in nature, rather than simply genetic. It’s the way Mr. Kelly’s genes are expressed, not the genes themselves, otherwise he would now be a new species. Important semantics aside, the changes were thought to be caused by “oxygen-deprivation stress, increased inflammation, and dramatic nutrient shifts that affect gene expression,” according to CNN. It’s important to both understand and solve these kinds of issues when it comes to prolonged space flight, travel to Mars, and other space-related activities, and the Kellys being part of this study will pay untold dividends towards that understanding.
