Scientists identify key enzyme in Alzheimer’s disease that links brain inflammation to memory loss

A research team at the Institute for Basic Science (IBS) has identified a previously unknown enzyme, SIRT2, that plays a key role in memory loss associated with Alzheimer’s disease (AD). The study, led by Director C Justin Lee, of the IBS Center for Cognition and Sociality, provides critical insights into how astrocytes contribute to cognitive decline by producing excessive amounts of the inhibitory neurotransmitter GABA.

From brain Bluetooth to ‘full RoboCop’: Where chip implants will be headed soon

In the 1987 classic film “RoboCop,” the deceased Detroit cop Alex Murphy is reborn as a cyborg. He has a robotic body and a full brain-computer interface that allows him to control his movements with his mind. He can access online information such as suspects’ faces, use artificial intelligence (AI) to help detect threats, and his human memories have been integrated with those from a machine.

A mysterious pathogen: Oropouche virus more common in Latin America than previously thought

Like the dengue and Zika viruses, Oropouche virus causes a febrile illness. There are recent indications that infections during pregnancy can cause damage to unborn babies. Researchers at Charité—Universitätsmedizin Berlin have now determined that the virus is much more widespread in Latin America than previously assumed. Their study, published in The Lancet Infectious Diseases, also suggests that climatic conditions have a significant influence on the virus’s spread.

Immune cell ‘messengers’ could save crumbling bones—new hope for joint pain sufferers

A recent study has uncovered a potential breakthrough in treating osteonecrosis of the femoral head (ONFH), a debilitating bone disease that causes severe pain and joint collapse. Researchers have discovered that exosomes derived from M2 macrophages-derived exosomes (M2-Exos) can significantly improve bone regeneration by modulating neutrophil extracellular traps (NETs) and endothelial cell function.
