PacWest Bancorp said late on Wednesday it was in talks with potential partners and investors about strategic options after shares of the Los Angeles-based lender and several other U.S. regional banks tumbled amid fears of a worsening banking crisis.
Peter Morici, professor emeritus at the University of Maryland, joined NewsNation Now to discuss.

Quantum Supremacy
Posted in computing, cosmology, quantum physics
We’re hearing this week from two very different parts of the string theory community that quantum supremacy (quantum computers doing better than classical computers) is the answer to the challenges the subject has faced.
New Scientist has an article Quantum computers could simulate a black hole in the next decade which tells us that “Understanding the interactions between quantum physics and gravity within a black hole is one of the thorniest problems in physics, but quantum computers could soon offer an answer.” The article is about this preprint from Juan Maldacena which discusses numerical simulations in a version of the BFSS matrix model, a 1996 proposal for a definition of M-theory that never worked out. Maldacena points to this recent Monte-Carlo calculation, which claims to get results consistent with expectations from duality with supergravity.
Maldacena’s proposal is basically for a variant of the wormhole publicity stunt: he argues that if you have a large enough quantum computer, you can do a better calculation than the recent Monte-Carlo. In principle you could look for quasi-normal modes in the data, and then you would have created not a wormhole but a black hole and be doing “quantum gravity in the laboratory”.
A few hours ago, the Fuego volcano erupted in Guatemala.
An orange alert has been declared.
The eruption resulted in the formation of ash columns over 5 km high.
Lava flows began to descend from the crater.
Abundant volcanic ash fell on nearby villages.
The evacuation of residents and the blocking of roads begins.
It is expected that the activity of the volcano will continue for at least another 24 hours.
Fuego is one of the most active volcanoes in the country.
It is located 40 km from the capital of Guatemala.

In pigs, scientists have succeeded in turning cardiac muscle cells into specialized pacemaker cells. Such technology could eventually replace electronic pacemakers, researchers say.
After a 60-year scientific quest, the world has its first vaccine to protect against respiratory syncytial virus, or RSV – and more are on the way.
On Wednesday, the US Food and Drug Administration approved Arexvy, made by GSK, which is designed to be given as a single shot to adults 60 and older.
It could be available for seniors as soon as this fall, pending a recommendation for its use from the US Centers for Disease Control and Prevention’s Advisory Committee on Immunization Practices, which next meets in June.

Ultra-high resolution mass spectrometry revealed that plastic bags leach labile compounds. Bioassays performed in Scandinavian lakes indicated that these compounds are incorporated into biomass faster and more efficiently than natural organic matter.

A deep slumber might help buffer against memory loss for older adults facing a heightened burden of Alzheimer’s disease, new research from the University of California, Berkeley, suggests.
Deep sleep, also known as non-REM slow-wave sleep, can act as a “cognitive reserve factor” that may increase resilience against a protein in the brain called beta-amyloid that is linked to memory loss caused by dementia. Disrupted sleep has previously been associated with faster accumulation of beta-amyloid protein in the brain. However, the new research from a team at UC Berkeley reveals that superior amounts of deep, slow-wave sleep can act as a protective factor against memory decline in those with existing high amounts of Alzheimer’s disease pathology —a potentially significant advance that experts say could help alleviate some of dementia’s most devastating outcomes.
“With a certain level of brain pathology, you’re not destined for cognitive symptoms or memory issues,” said Zsófia Zavecz, a postdoctoral researcher at UC Berkeley’s Center for Human Sleep Science. “People should be aware that, despite having a certain level of pathology, there are certain lifestyle factors that will help moderate and decrease the effects.
