Will physics prevent SpinLaunch from succeeding?
SpinLaunch has a working prototype successfully launching objects at 1,000 miles-per-hour, but will the laws of physics stand in the way?
Extra-salty lithium battery less likely to catch fire
Stanford researchers have developed a battery electrolyte that can allow lithium-ion batteries to operate safely at much higher temperatures.
Here’s what that fusion power breakthrough really means
This year, NIF reports that it has achieved "ignition" — that is, it has achieved slightly more fusion energy output than laser energy input.
A green trifecta: how a concrete alternative can cut emissions, resource use, and waste
Building materials and construction generate about 20% of global greenhouse gas emissions. What if there was an alternative?
This meteorite material could power our clean energy future
A lab-made version of tetrataenite, a mineral found in meteorites, could replace rare earth elements in the production of permanent magnets.
UK test-fires its first high-energy laser weapon
The UK has successfully test-fired the $115 million DragonFire, its first high-powered, long-range laser weapon.
Chernobyl fungus could shield astronauts from cosmic radiation
A recent study tested how well the fungi species Cladosporium sphaerospermum blocked cosmic radiation aboard the International Space Station.
A new material called a mechanical neural network can learn and change its physical properties
The new material’s architecture is based on that of an artificial neural network – layers of interconnected nodes that can learn to do tasks.
New VR body suit lets you see inside your body while you exercise
A system for monitoring motion and muscle engagement could aid the elderly and athletes during physical rehabilitation.
How to prevent mass extinction in the ocean using AI, robots, and 3D printers
There is currently no possibility of the world reaching the 30% target for marine protected areas with existing policies. Tech to the rescue?
