Nearly three years into the pandemic, travel has returned but hotel staff have not. Unable to find workers, hotel owners and managers are having to adapt to what they believe is the new normal.

Over the last half-decade, quantum computing has attracted tremendous media attention. Why?
After all, we have computers already, which have been around since the 1940s. Is the interest because of the use cases? Better AI? Faster and more accurate pricing for financial services firms and hedge funds? Better medicines once quantum computers get a thousand times bigger?
New research published in the Annals of Clinical and Translational Neurology on December 7 has identified three genes and their expressed proteins that may be involved in the pathogenesis of multiple sclerosis.
By comparing information on the genes and proteins expressed in the brains of thousands of individuals with and without multiple sclerosis, investigators discovered different expression levels of the SHMT1, FAM120B, and ICA1L genes (and their proteins) in brain tissues of patients versus controls.
Studying the functions of these genes may uncover new information on the mechanisms involved in the development and progression of multiple sclerosis. “Our findings shed new light on the pathogenesis of MS and prioritized promising targets for future therapy research,” the authors wrote.
A new study shows that AI makes doctors better at screening cancer even when the AI sorts over half of scans automatically, dramatically reducing radiologists’ workloads.
Lasers find applications across several fields ranging from telecommunications and remote sensing to medicine. There are many ways in which one can generate laser emission, or lasing, from a device or material. Consequently, there are many types of lasers with different principles of operation.
One emerging and promising method to achieve lasing with high energy efficiency is by leveraging what are known as “bound states in the continuum” (BICs). In simple terms, these states describe waves that remain highly localized in space but coexist with a continuous spectrum of waves that are not localized (traveling waves). When dealing with light, an electromagnetic wave, BICs can be realized by carefully designing the geometry of a confining periodic structure.
Although scientists have already reported a few types of BIC-based lasers, most of them can only emit a beam in a perfectly or almost perfectly vertical direction away from the surface of the device. This limitation hinders the use of such BIC lasers in applications where angling the emitted beam is necessary.

Researchers have studied how irregularly shaped particles travel through microchannels. Their work could have relevance to the transport of red blood cells through capillaries.
In a recent study posted to the bioRxiv server, researchers in Germany investigated the effectiveness of the antibiotic nitroxoline against the currently circulating mpox viruses, previously called monkeypox virus (MPXV). This antibiotic has been used in Europe for about fifty years and has been proven effective in fighting biofilm infections.
