Humanity receives mysterious 'mega-laser' signal from unknown source

This system is truly extraordinary. We are seeing the radio equivalent of a laser halfway across the universe. This galaxy acts as a lens, the way a water droplet on a window pane would, because its mass curves the local space-time. So we have a radio laser passing through a cosmic telescope before being detected by the powerful MeerKAT radio telescope.

A century after the first rocket launch, Ars staffers pick their favorites

Robert Goddard, a Massachusetts-born physicist, launched the world's first liquid-fueled rocket on this date 100 years ago. It was not an overly impressive flight. The rocket, fueled by gasoline and liquid oxygen, rose just 41 feet into the air, and the flight lasted 2.5 seconds before it struck ice and snow. Nevertheless, this rocket, named "Nell," represented a historic achievement that would help launch the modern age of spaceflight.

The science of how fireflies stay in sync

The fireflies were most likely to change their own flashing rhythm in response when the LED blinked almost, but not quite, at the same time as the fireflies. The males would speed up their next flash if the LED blinked just before and waited a bit longer for their next flash when the LED blinked right after.

Direct conversion from alkenes to alkynes

Alkynes are widely used as feedstock chemicals and functional groups in organic chemistry. However, while the hydrogenation from an alkyne to an alkene is well established, typical methods for the reverse reaction—conversion of an alkene to an alkyne—are based on elimination chemistry reported in the 1860s and use forcing conditions (strong base or high temperatures).
