⚒️ 🧪 A M6.8 earthquake struck Kyushu, Japan today. Large quakes in Japan are common and often pass without much notice, but this one is serious - instead of occurring offshore in the subduction zone, it is a shallow, strike-slip event near Kumamoto. Damage and deaths have already been reported.

1/6 In 2025, Gemini North data gave only a weak 1.5σ hint of a companion near Betelgeuse — a signal just strong enough to notice.🔭 The new VLT/SPHERE data raise the detection to a solid 6.1σ level (5.1σ with another method), making the result far more convincing & confirming the same location.🧪⚛️

The conclusion of a century-long quest 😲 Our VLT obtained firm evidence that Betelgeuse, a red supergiant star in the Orion constellation and one of the most famous stars in the night sky, is not alone! 🔭 🧪 1/4

An inset image zooms into the star Betelgeuse, showing its orange surface. A second inset shows a bright companion next to the star. Image by ESO/M. Montargès et al. Background: N.

Batteries based on sodium ions are entering mass production. Nature reports how some researchers say they could ultimately be a cheaper, safer alternative to lithium in electric cars and other energy applications. 🌎🧪

This is Nymeria. She is demonstrating the rare compact zoomies. Ideal for situations where you don't have much room, but still must zoom. 13/10 (TT: ouruntamedtale)

It can't just be dinosaurs *all* the time. For this week's #FossilFriday, here are some lovely fossil leaves from the Late Cretaceous of Wyoming. Plant fossils like this are crucial for understanding these ancient ecosystems, giving us information about everything from rainfall to C02 levels

Great apes may have been laughing with a similar rhythm to modern humans for at least 15 million years, suggests a study in Communications Biology. The findings also suggest that laughter has become faster, more variable, and increasingly influenced by the situation it occurs in. #evosky 🌎🧪

Rhythm and timing in laughter reveal that human vocal plasticity falls on a hominid continuum - Communications Biology

Comparative analysis of laughter rhythm across all extant great apes reveals that isochrony is ancestral to hominids, with tempo, variability, and context-sensitivity increasing progressively toward humans, tracing a continuum of vocal plasticity.
