Study Reveals Key Alzheimer’s Pathway — And Blocking It Reverses Symptoms in Mice

A sequence of stress signals among specialized clean-up cells in the brain could at last reveal why some immune responses can cause significant nerve degeneration that results in the loss of memory, judgement, and awareness behind Alzheimer’s disease.

Blocking this pathway in mouse brains modeled on Alzheimer’s prevented damage to their synapse connections and reduced the buildup of potentially toxic tau proteins – both hallmarks of the condition.

The researchers, led by a team from the City University of New York (CUNY), believe this pathway – called the integrated stress response (ISR) – causes brain immune cells called microglia to go ‘dark’ and start damaging rather than benefiting the brain.

Scientists develop vaccine test that predicts how long immunity lasts

A blood test that can predict how long vaccine immunity will last so people can get a booster jab earlier, is being developed by scientists.

Researchers have previously been unable to predict why some vaccines produce antibodies to fight infections that last for decades while in others immunity only lasts a few months.

Now Stanford University has found tell-tale signs in the blood in the days after vaccination to indicate how quickly a person’s antibody protection will wane.

Light-Switching Nanocrystals Ignite the Future of AI and Computing

Researchers have discovered nanocrystals that toggle between luminescent states swiftly, offering a promising advancement toward optical computing.

This technology could revolutionize data processing and artificial intelligence, making devices faster and more energy-efficient while expanding capabilities in telecommunications and medical imaging.

China claims 6G-level space-ground laser transmission speed achieved

SCMP stated this latest achievement of 100Gbps transmission rate is said to be equivalent to transmitting ten full-length movies within a “single second.”

This development in satellite-to-ground laser communication will significantly enhance China’s space capabilities. It will pave the way for improved satellite infrastructure, including navigation, 6G internet, and remote sensing.
