Neutron Stars with Baryon Number Violation, Probing Dark Sectors
Posted by Dan Breeden in categories: particle physics, space
The neutron lifetime anomaly has been used to motivate the introduction of new physics with hidden-sector particles coupled to baryon number, and on which neutron stars provide powerful constraints. Although the neutron lifetime anomaly may eventually prove to be of mundane origin, we use it as motivation for a broader review of the ways that baryon number violation, be it real or apparent, and dark sectors can intertwine and how neutron star observables, both present and future, can constrain them.

First functional human brain tissue produced through 3D printing
Posted by Shubham Ghosh Roy in categories: 3D printing, biotech/medical, neuroscience
A team of researchers has created the first functional 3D-printed brain tissue to examine the brain’s function and study various neurological disorders.
The first functional 3D-printed brain tissue has been developed to examine the human brain’s function and study various neurological disorders.
According to experts at the University of Wisconsin-Madison, printed tissue can “grow and function like typical brain tissue.”

How Invisible Light Is Shaping the Future of High-Speed Computing
Posted by Genevieve Klien in categories: computing, materials
New ultrafast method for controlling magnetic materials might enable next-generation information processing technologies.
As demands for computing resources continue to increase rapidly, scientists and engineers are looking for ways to build faster systems for processing information. One possible solution is to use patterns of electron spins, called spin waves, to transfer and process information much more rapidly than in conventional computers. So far, a major challenge has been in manipulating these ultrafast spin waves to do useful work.
Breakthrough in Spin Wave Manipulation.
It started as a big old ball of dust, so how did it end up like a giant pancake? Our resident physicist tells the true story using fake forces.

Methods of Lysergic Acid Synthesis—The Key Ergot Alkaloid
Posted by Quinn Sena in category: futurism
Ergot is the spore form of the fungus Claviceps purpurea. Ergot alkaloids are indole compounds that are biosynthetically derived from L-tryptophan and represent the largest group of fungal nitrogen metabolites found in nature. The common part of ergot alkaloids is lysergic acid. This review shows the importance of lysergic acid as a representative of ergot alkaloids. The subject of ergot and its alkaloids is presented, with a particular focus on lysergic acid. All methods of total lysergic acid synthesis—through Woodward, Hendrickson, and Szantay intermediates and Heck coupling methods—are presented. The topic of biosynthesis is also discussed.

Biotech is the new focus in U.S.-China tech rivalry
Posted by Dan Breeden in categories: biotech/medical, economics, food, security
The need to quash outbreaks, quickly create medicines, stress-proof crops and fend off other 21st century threats is providing a lucrative arena for biotech companies to sell their services.
Why it matters: But the infrastructure to support such ambitions is increasingly recognized by the U.S., China and other countries as a linchpin of national security and economic strategy, putting it at the center of geopolitics.
