A Vancouver-based dermatologist, Dr Katie Beleznay, board-certified in both Canada and the US demonstrated how Botox works by injecting only one side of her husband Ben’s face. The controlled experiment showed, in real time, how neuromodulators soften lines, relax specific muscles and subtly change symmetry. Her video demystified a treatment often associated with extremes, offering a clear, practical look at its real effects.

A YouTuber’s decision to slip a GoPro into an air fryer, briefly, at low heat, offered thousands a rare look inside a kitchen staple we rarely question. The short clip, showing the fan and coil in quiet action, surprised viewers who realised they’d never actually seen how the device works. A simple, safe demonstration answered a very everyday curiosity.

Scientists at Radboud University say the universe will fade out far sooner than once believed, not in 10¹¹⁰⁰ years, but in roughly 10⁷⁸. Their calculations build on Stephen Hawking’s idea that black holes slowly evaporate, extending the process to neutron stars and white dwarfs. As these final stellar remnants dissolve, all luminous matter eventually disappears, marking the universe’s theoretical end.

Scientists now think the universe may be filled with tiny “primordial” black holes, relics from the first moments after the Big Bang, drifting through Earth by the thousand each year and passing through our homes and bodies without leaving a trace. These minuscule singularities may even be the missing dark matter, a possibility that could reshape how we understand the universe’s hidden mass.

Researchers are exploring the idea that one hemisphere of Earth, dominated by the Pacific Ocean, is losing internal heat faster than the continental side. This phenomenon, driven by differences in crust thickness and composition, has been shaping plate tectonics and volcanic activity over millions of years. The uneven cooling provides insights into Earth's long-term geological evolution and mantle circulation patterns.
