Discovery of new role for the brain’s immune cells could have Alzheimer's implications

The immune cells, known as microglia, also help regulate blood flow and maintain the brain's critical blood vessels, researchers have discovered. The findings may prove important in cognitive decline, dementia and stroke, among other conditions linked to diseases of the brain's small vessels.

Contraceptive pill can reduce type 2 diabetes risk in women with polycystic ovary syndrome

A study has revealed for the first time that the contraceptive pill can reduce the risk of type 2 diabetes by over a quarter in women with polycystic ovary syndrome (PCOS). The research findings also show that women with PCOS have twice the risk of developing type 2 diabetes or pre-diabetes (dysglycemia) -- highlighting the urgent need to find treatments...

Gel fights drug-resistant bacteria and induces body’s natural immune defense

In the fight against multidrug-resistant bacteria, scientists have developed a new kind of antibiotic-free protection for wounds that kills drug-resistant bacteria and induces the body's own immune responses to fight infections.

Study could pave way for creating safer opioids

Researchers may have an uncovered new answers on how to create safer opioids. Design a new opioid to bypass the part of brain that feels pleasure, but retain the analgesic properties, which make opioids one of the most effective pain relievers. Researchers looked at how opioids may have become so widely abused.

How long can fiber reinforced polymer sustain concrete structures? Scientists answer

One potential cost-effective way to sustain ageing concrete subjected to harsh environmental conditions is to externally coat the material with fiber reinforced polymer composites. But few studies have looked at the durability of such strengthening. Now, researchers from Korea and the USA conduct a 13-year long experiment to find out.
