• Human Embryo Gene Editing Gets a Road Map—Not a Green Light

    For that reason, the authors of the report lay out exactly how many and what kind of off-target effects might be acceptable. They put that threshold at no more than the average rate of new mutations an embryo spontaneously acquires. DNA replication isn’t perfect, and most people are born with a few dozen mutations that don’t exist in either of their biological parents’ genomes. Gene editing shouldn’t introduce any more genetic variations than occur naturally, the authors concluded, and the types of changes should be carefully studied in the lab to make sure they don’t lead to adverse outcomes.

    The trouble is, though, that right now there aren’t any good methods for assessing off-target effects in embryos. Doing so requires collecting large amounts of DNA, which can only be done by sacrificing a number of cells from the embryo for genetic sequencing. In addition to being unreliable, these methods harm

  • This Game Boy doesn’t need batteries, but shuts off every 10 seconds

    The original Game Boy from 1989 was an iconic handheld console but, as anyone who owned one will tell you, it required a steady stream of batteries to keep running. Now, a team of researchers at Northwestern University and Delft University of Technology have developed a new take on the classic console, replacing its array of four AA batteries with a set of five rows of solar panels and buttons that harvest power as you play.

    The Engage, as the team have called their device, is theoretically capable of being used to play any game made for the original Game Boy, and it’s even got a slot on its back if you want to insert an original game cartridge. It’s about the size of a paperback book, but as CNET reports, it only weighs half as much as the original handheld.

  • Robert Pattinson has tested positive for COVID-19. What does this mean for ‘The Batman’?

    It seems that Hollywood actors, despite how invincible they seem on the silver screen, aren’t immune to the coronavirus.

    After Dwayne ‘The Rock’ Johnson announced he and his family had all tested positive for COVID-19, the next Bruce Wayne, aka Batman, has tested positive for the deadly virus.

    In case you’re still scratching your head, it’s Robert Pattinson, of tween novel and movie franchise Twilight fame.

    Filming had originally been planned a lot earlier, but due to the coronavirus pandemic and increasingly stringent border restrictions across the globe, it had to be halted in March 2020. Six whole months went by before filming could resume again.

    When the United Kingdom finally eased restrictions, allowing actors to fly into the country for movie shoots, things seemed like they were about to get back on schedule.

    Filming for The Batman had only just resumed
