By briefly inhibiting other cells, neurogliaform cells in the CA1 region of the hippocampus ensure that current perception and memories of past experiences can be processed both separately and in combination with each other.
White House asks the public for ideas on what to do when we return to the Moon and cislunar space.
The U.S. has plans to return to the moon by the middle of this decade through NASA’s Artemis Program. But going back to the lunar surface and cislunar space isn’t just about putting boots on the ground. That’s why the White House Office of Science and Technology Policy on behalf of the Cislunar Science and Technology Subcommittee of the National Science and Technology Council has issued a request for ideas (RFI) with a deadline of Wednesday, July 20, 2022, for interested parties to make submissions.
The U.S. government has defined cislunar space as the entire region beyond Earth’s geostationary orbit subject to the gravity of both our planet and the Moon. The RFI covers both orbiting and lunar surface activities.

The team behind the first Chinese X-ray astronomy satellite, Insight-HXMT, has discovered the strongest magnetic field directly measured in the universe hitherto.
It is a known fact that neutron stars generate the strongest magnetic fields in the universe. These magnetic fields, close to a neutron star’s surface, can only be measured accurately and directly by looking for cyclon resonance scattering features (CRSF). The Insight-HXMT team discovered a cyclotron absorption line with an energy of 146 keV in the neutron star X-ray binary Swift J0243.6+6124, which translates to a surface magnetic field of more than 1.6 billion Tesla.
Lasers normally use mirrors to create laser light, but a new kind uses clumps of moving particles. The result is a laser that is more programmable and could generate extra-sharp visual displays.

TRISO particles cannot melt in a reactor and can withstand extreme temperatures well beyond the threshold of current nuclear fuels.
There’s a lot of buzz around advanced nuclear.
These technologies are going to completely change the way we think about nuclear reactors.

Biological synapses are known to store multiple memories on top of each other at different time scales, much like representations of the early techniques of manuscript writing known as “palimpsest,” where annotations can be superimposed alongside traces of earlier writing.
Biological palimpsest consolidation occurs via hidden biochemical processes that govern synaptic efficacy at varying lifetimes. The arrangement can facilitate idle memories to be overwritten without forgetting them, while using previously unseen memories short-term. Embedded artificial intelligence can significantly benefit from such functionality; however, the hardware has yet to be demonstrated in practice.
In a new report, now published in Science Advances, Christos Giotis and a team of scientists in Electronics and Computer Science at the University of Southampton and the University of Edinburgh, U.K., showed how the intrinsic properties of metal-oxide volatile memristors mimicked the process of biological palimpsest consolidation.
