Antimatter is the counterpart to regular matter, but with an opposite electric charge, as well as other differences. So if it’s the opposite of normal matter, does it fall up instead of down? Studying antimatter is notoriously difficult, but scientists at CERN have scraped together just enough to take a closer look at its behaviour under gravity – their results are consistent with Albert Einstein’s predictions.

With remote school and work during the covid-19 pandemic, it’s no wonder telehealth startups popped up all over the US. With telemedicine, you don’t even need to leave your house to get a prescription – medicine can be delivered straight to your door, a boon for people who live in remote areas or have other difficulties in accessing a doctor’s office.

Move over cows, there’s a new ‘moo’ in town. It turns out crocodiles can moo too – African dwarf crocodiles to be exact. In an effort to monitor their populations remotely, scientists have been recording the surprising noises they make.
