During implicit learning, the authors find that sensory representations in mouse auditory cortex evolve over time, rotating into orthogonal memory representations. This allows short-term memories to avoid interference from new sensory inputs.

Inspired by the lush oases in Tunisia, a Belgian artist has developed a ‘portable oasis’, cocooning his head in a bubble of air purified by the aromatic plants inside https://reut.rs/3apLI6G
It can track objects the size of a golf ball traveling at up 30000 kilometers per hour in LEO.
There’s a new giant space radar in Costa Rica that can track orbital debris as small as two centimeters. It was built by LeoLabs, a company that provides commercial radar tracking services for objects in Low Earth Orbit, which has declared the site fully operational less than a year after breaking ground. LeoLabs CEO Dan Ceperley said it’s the “most advanced commercial space radar of its kind” — one that’s capable of tracking objects the size of a golf ball traveling at up 30000 kilometers per hour.
The radar can keep an eye on both active satellites and space junk, which make up the vast majority of man-made objects found in LEO. They’re also the risks LeoLabs’ customers — made up of satellite operators, defense, space and regulatory agencies, insurance and scientific institutions — want to keep tabs on.

This 32000-year-old plant was long gone until scientists found its incredibly preserved seeds in Siberia and brought it back to life!
Users can input a specific address or more generalized region, such as a state or country, and then choose a date ranging from zero to 750 million years ago.
The interactive tool enables users to home in on a specific location and visualize how it has evolved between the Cryogenian Period and the present.
Russian firm Aerosmena’s plans to build enormous cargo airships may be more than just hot air.
Splitting water using suspensions of particulate carbon nitride-based photocatalysts may be a cheap way to produce hydrogen, but efficiencies have remained low. Now, Shen and colleagues use doped carbon nitride-based Z-scheme heterostructures to split water with a solar-to-hydrogen efficiency of 1.1% in the presence of metal-based co-catalysts.
