LHS 1140b is a super-Earth tidally locked to its small, quiet red dwarf star, and thanks to recent JWST observations, we think it is a cold eyeball planet: frozen all over except for a liquid ocean directly facing the dim star. sci.news/astronomy/habi…

The Mitsubishi Air Lubrication System (MALS) that lets ships ride on a low-friction 'air carpet': youtu.be/1RZ0UOIITMk It was already demonstrated to reduce fuel consumption by 13% in its first trials.

Nuclear breakthrough beyond theory: a Japanese cyclotron has managed to create Sodium-39. This isotope has 2.5x more neutrons than protons. It was thought impossible but here it is: physics.aps.org/articles/v15/1…

Plasma is better in colour! Watch one of our latest #plasma pulses in our ST40 tokamak, filmed using our new high-speed colour camera at an incredible 16,000 frames per second. Each pulse lasts around a fifth of a second. What you’re seeing is mostly visible light from the

Rocket engineers have long had to choose between performance and toxicity. The TOXMAX rocket concept resolves the problem decisively. Lithium kept molten by radioactive Cesium-137, reacting with fluorine, provides superlative performance with maximum environmental impact.

At this frame-rate, we can clearly see the many micro-corrections the onboard flight computer does through the fly-by-wire system:

The bacterial flagellar motor can spin at 100,000 RPM in one direction, then switch gears and flip to spinning in the other direction. How does this work? Cryo-electron microscopy reveals some of the nanoscale mechanics involved: nature.com/articles/s4156… youtu.be/MsPPyNWhqPo

A method to unilaterally disable all nuclear bombs on Earth, remotely and without countermeasure: arxiv.org/pdf/hep-ph/030… It uses a 1000 TeV muon->neutrino beam to penetrate right through the Earth and decay near fissile material, forcing it to 'fizzle' and become useless.

Why were aircraft manufacturers so eager to switch from high-performance piston engines to jet engines, despite all their early drawbacks? The insane level of complexity piston engine design had reached is one reason. Compare cross-sections and number of moving parts here:

A 2000 ton spaceship that's 900 tons antihydrogen, 900 tons hydrogen and 200 tons engines, structure and payload would have a deltaV of 1.59 C. It can accelerate to 0.92C with 2.55x time dilation, enough to reach the closest star in 21.4 months subjective time.
