Mars geology is literally speaking cooler than on Earth; Researchers think gullies on Martian dunes can be formed by CO2 blocks... 🧊 🧪

Science X / Phys.org @sciencex.bsky.social · 1d

Experiments show that gullies on Martian dunes can be formed by CO₂ ice blocks burrowing downslope through sublimation, a process not observed on Earth. doi.org/g96v4c

Mysterious gullies on Mars appear to have been carved by burrowing CO₂ ice blocks

Did life really exist on Mars after all? Unfortunately, there is no conclusive evidence for this yet. Nevertheless, it would seem that some form of life was the driving force behind the mysterious Martian dune gullies.

Why study boring things when you can study nature's beauty? Researchers provide first complete mathematical description of stalagmite shapes: 🧪

Science X / Phys.org @sciencex.bsky.social · 2d

A complete mathematical model now explains how stalagmite shapes—flat-topped, columnar, or conical—arise from the interplay between water flow and calcite precipitation in caves.

Drip by drip: Research provides first complete mathematical description of stalagmite shapes

Deep inside caves, water dripping from the ceiling creates one of nature's most iconic formations: stalagmites. These pillars of calcite, ranging from centimeters to many meters in height, rise from the cave floor as drip after drip of mineral-rich water deposits a tiny layer of stone.

Quitting smoking in middle age or later is associated with a slower rate of cognitive decline over time, with notable benefits for memory and verbal fluency compared to continued smoking.

Quitting smoking, even late in life, linked to slower cognitive decline

Quitting smoking in middle age or later is linked to slower age-related cognitive decline over the long term, according to a new study by UCL (University College London) researchers.

💪 Plant vs animal protein in training

In a 12-week trial, men who took plant or animal protein with resistance training gained similar muscle mass and strength. Both sources were equally effective.

Startup plans to use orbiting mirrors to deliver sunlight after dark. (A product for people who post on X at nighttime.) ☀️🧪

Science X / Phys.org @sciencex.bsky.social · 4d

A US startup proposes using thousands of orbiting mirrors to beam sunlight to Earth after dark, raising significant concerns about light pollution and impacts on astronomy and wildlife.

A US startup plans to deliver 'sunlight on demand' after dark. Can it work? Would we want it to?

A proposed constellation of satellites has astronomers very worried. Unlike satellites that reflect sunlight and produce light pollution as an unfortunate byproduct, the ones by US startup Reflect Orbital would produce light pollution by design.

ja, det er oppsiktsvekkande! Kvar er analysane, kommentatorane, politikarane? "Enemy-within"-talen er jo eit enormt skummelt veiskille. Det begynner å bli ein dårlig vits at Nato skal forsvare "common values of individual liberty, democracy, human rights and the rule of law."
