There’s a hallmark of incurable neurodegenerative diseases – misfolded proteins that clump together to form sticky plaques or tangles called fibrils.

Now, new research has discovered that a protein normally tasked with clearing cells of molecular debris might be a common feature of a cluster of common and rare neurodegenerative diseases, including two distinct forms of dementia.

The finding was “both unexpected and surprising” and “raises many intriguing questions”, according to the team behind the study, who made 3D-reconstructions of a twisted protein they found in “copious amounts” in some brain tissue samples.

What happens to information after it has passed beyond the event horizon of a black hole? There have been suggestions that the geometry of wormholes might help us solve this vexing problem – but the math has been tricky, to say the least.

In a new paper, an international team of physicists has found a workaround for better understanding how a collapsing black hole can avoid breaking the fundamental laws of quantum physics (more on that in a bit).

Although highly theoretical, the work suggests there are likely things we are missing in the quest to resolve general relativity with quantum mechanics.

Superconductors—metals in which electricity flows without resistance—hold promise as the defining material of the near future, according to physicist Brad Ramshaw, and are already used in medical imaging machines, drug discovery research and quantum computers being built by Google and IBM.

However, the super-low temperatures conventional superconductors need to function—a few degrees above absolute zero—make them too expensive for wide use.

In their quest to find more useful superconductors, Ramshaw, the Dick & Dale Reis Johnson Assistant Professor of physics in the College of Arts and Sciences (A&S), and colleagues have discovered that magnetism is key to understanding the behavior of electrons in “high-temperature” superconductors. With this finding, they’ve solved a 30-year-old mystery surrounding this class of superconductors, which function at much higher temperatures, greater than 100 degrees above absolute zero. Their paper, “Fermi Surface Transformation at the Pseudogap Critical Point of a Cuprate Superconductor,” published in Nature Physics March 10.

Another set of strange excuses for not sending air power so Ukraine can defend itself. 1/8.

Spain houses just over a third or 35% of the liquefied natural gas (LNG) storage capacity in the EU and the UK, according to data from Gas Infrastructure Europe (GIP), the association of European gas infrastructure operators, comprising 67 companies from 26 countries. [INSAGO / Shutterstock].

Democratic values were already under threat around the world before the Russian invasion of Ukraine. Now we need to rekindle the spirit of 1989.
