The proteins that make cell-to-cell cargo transport possible

Sciencedaily.com 

Scientists have revealed the secret to the structural integrity of tiny particles that transport cargo from cell to cell through blood vessels and bodily fluids: special proteins that keep their membranes intact as they negotiate shifting electrical impulses in different biological environments.

Xenon gas could protect against Alzheimer's disease: Mouse study

Sciencedaily.com 

Most treatments being pursued today to protect against Alzheimer's disease focus on amyloid plaques and tau tangles that accumulate in the brain, but new research points to a novel -- and noble -- approach: using Xenon gas. The study found that Xenon gas inhalation suppressed neuroinflammation, reduced brain atrophy, and increased protective neuronal states in mouse models of Alzheimer's disease. A phase 1 clinical trial of the treatment in healthy volunteers will begin in early 2025.

Fatal neurodegenerative disease in kids also affects the bowel

Sciencedaily.com 

Researchers have described the neurodegeneration that occurs in the nervous system of the bowel in Batten disease, a rare and fatal genetic condition. In their latest study, a team showed that gene therapy to the bowel in mice modeling Batten disease reduced symptoms and extended lifespan.

Conquest of Asia and Europe by snow leopards during the last Ice Ages uncovered

Sciencedaily.com 

Scientists have identified fossils of snow leopards. The discovery has allowed them to trace the evolutionary history of the species during the Quaternary period and to propose how it dispersed from the Tibetan plateau to the Iberian Peninsula, far from the high and icy Himalayan mountains.

Protein protects biological nitrogen fixation from oxidative stress

Sciencedaily.com 

A research team has discovered how the 'Shethna protein II' protects the nitrogen-fixing enzyme nitrogenase from damage. The oxygen sensor protein could help to make nitrogenase usable in biotechnology, thereby reducing the need for synthetic fertilizers.

These Black American Billionaires Could Save TikTok

TheRoot.com 

By Sunday, January 19, TikTok will likely be banned in the U.S. Although the app will still be available for users who have it downloaded on their mobile devices, it won’t be found on app stores to download, meaning it can no longer be updated.
