Choose whichever real-feeling headline your imagination will run wildest with. Don't overthink it.

Apple has filed a patent application that describes using motion sensing to detect lip and head movements so Siri could recognize commands without relying only on a microphone. The filing, titled "Keyword Detection Using Motion Sensing," explains how analyzing mouth shapes and subtle head motions might identify common phrases, which could help the assistant work better in noisy environments or avoid false activations from background speech.

China's Chang'e-4 lander touched down on the Moon's far side in January 2019. Using instruments including ground-penetrating radar, the mission collected subsurface profiles near its landing site. A team writing in the Journal of Geophysical Research: Planets reports the top roughly 130 feet (about 40 metres) of the surface is layered—alternating dust, soil and broken rock—and that a buried impact crater lies within those layers.

On Saturday at Thredbo Ski Resort in New South Wales, a chair on the Kosciuszko chairlift detached after what the resort described as an unexpected gust of wind. The Kosciuszko is Australia’s longest ski lift. Three snowboarders in their twenties—two women and one man—fell several metres onto the snow near Eagles Nest and suffered facial and back injuries. Resort staff and emergency responders attended the scene; the incident has been described by Thredbo as isolated and unusual.

In 2009 the Large Hadron Collider (LHC), a giant particle accelerator near Geneva run by CERN, was preparing to restart after upgrades. Scientists said the machine would smash protons together at very high energies to study fundamental particles and forces, potentially revealing phenomena such as the Higgs boson or signs of new physics. However, some members of the public expressed fear that the machine could produce catastrophic effects, including miniature black holes or other unknown dangers.
