Pro, pre, and postbiotics: the changing landscape of skincare

The skin is the largest organ of the human body, and perhaps the only one that universally receives the most care and attention. We cleanse it daily with branded cleansers and soaps; moisturise it with exotic, fragrant creams and lotions; and protect it with sunscreens that promise high SPFs. Skincare, in 2025, is a booming…

Clearest black hole merger signal yet allows probe of Hawking’s law

On September 14, 2015, researchers using a pair of giant detectors in the US detected gravitational waves for the first time — a century after Albert Einstein predicted their existence  in his general theory of relativity. For their contributions to building these detectors, called the Laser Interferometer Gravitational-wave Observatories (LIGO), Rainer Weiss, Kip Thorne, and…
