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 government is seeking help in creating research priorities, technical standards and the development of a sustainable presence for human activity in cislunar space.

Forcing them to become servants could have a bad outcome. See the latest episode of The Orville, “From Unknown Graves”. https://www.imdb.com/title/tt12037520

Ron HelwigThe Orville keeps getting better. It’s already the best Trek.

Ron Helwig I find it very similar to the original Star Trek from the 60s.

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.

Surveillance, Preparedness & Health Security In Critical Disease Emergencies — Dr. Rosamund Lewis, MD, Head, WHO Smallpox Secretariat, Technical Lead for Monkeypox.

Dr. Rosamund Lewis, MD, is Head, WHO Smallpox Secretariat, Emerging Diseases and Zoonoses Unit, World Health Emergencies Programme, at the World Health Organization in Geneva, Switzerland, leading on emergency preparedness and advising on health security for the agency in this very critical domain, including as technical lead for Monkeypox. She also holds an appointment as Adjunct Professor in the School of Epidemiology and Public Health, University of Ottawa.

Previous to this role, Dr. Lewis joined the WHO COVID-19 response team as the health sciences lead for management of infodemics.

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.

More than 70 projects are underway in the United States with new designs that are expected to be more economical to build and operate.

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 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 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.

Moore’s law has driven the semiconductor industry to continue downscaling the critical size of transistors to improve device density. At the beginning of this century, traditional scaling started to encounter bottlenecks. The industry has successively developed strained Si/Ge, high-K/metal gate, and Fin-FETs, enabling Moore’s Law to continue.

Now, the critical size of FETs is down to 7 nm, which means there are almost 7 billion transistors per square centimeter on one chip, which brings huge challenges for fin-type structure and nanomanufacturing methods. Up to now, extreme ultraviolet lithography has been used in some critical steps, and it is facing alignment precision and high costs for high-volume manufacturing.

Meanwhile, the introduction of new materials and 3D complex structures brings serious challenges for top-down methods. Newly developed bottom-up manufacturing serves as a good complementary method and provides technical driving force for nanomanufacturing.
