Fly Eyes in Drasophila

00:46 How flies can move their eyes (a little)

It's long been assumed flies’ eyes don’t move, and so to alter their gaze they need to move their heads. Now, researchers have shown that this isn’t quite true and that fruit flies can actually move their retinas using a specific set of muscles, which may allow them to perceive depth. The team also hope that this movement may provide a window into some of the flies’ internal processes.

11:11 Calls to mandate militaries’ emissions reporting

The eyes of the world will be focused on the UN’s upcoming COP27 conference to see what governments will pledge to do to reduce global emissions. But there’s one sector of countries’ carbon outputs that remains something of a mystery: the emissions of their militaries. We speak to Oliver Belcher, one of a group of researchers who have written a Comment article for Nature, calling for better reporting and greater accountability for these military emissions.

Comment: Decarbonize the military — mandate emissions reporting
