3D bioprinted algae can be harnessed as a sustainable source of oxygen for human cells in engineered vascularized tissues, researchers report. They embedded the bioprinted photosynthetic algae, along with human liver-derived cells, in a 3D hydrogel matrix to create honeycomb-shaped tissues with lobules, similar to the human liver.

UK Officials: Useless Emails Are Killing the Planet
Warm Regards If you don't have anything to say, perhaps don't press "send." The massive number of useless emails sent every day apparently takes a substantial toll on the environment, the BBC reports . As a result, U.K. officials are expected to soon ask everyone to stop sending out messages unless they actually have something to say. Unfortunately, it's not clear that it will do much to save the
