Ceramic/metal interface fracture toughness

Researchers evaluated the fracture toughness of Si3N4/S45C joints with interface cracks of different lengths. The specimen with a 4mm crack exhibited higher apparent fracture toughness due to reduced residual stress. Fracture propagation directions varied depending on crack length.

Serving up suds a hazardous task

A joint study by University of Alberta and Napier University of Scotland found bartending has the highest potential for injury in pubs, with workers at risk of back pain and shoulder strain. The study recommends changes such as reducing bar height, installing slip-free floors, and using dollys to move heavy loads to prevent injuries.

Scientists show that tick-borne flaviviruses use a novel mechanism to evade host defenses

Researchers have discovered a novel mechanism used by tick-borne flaviviruses to counteract the natural ability of interferon to combat the virus. The study found that NS5 protein blocks immune defenses, preventing the immune system from stopping the spread of the virus and helping the body recover from infection.

Seniors with low age expectations likelier to lead sedentary lives, new UCLA study finds

A new UCLA study found that seniors with the lowest expectations for aging were more than twice as likely to report engaging in less than 30 minutes of moderate to vigorous activity. Increasing physical activity can improve health outcomes for older adults, making it a powerful way to address common age-related health issues.

Flavanols key to potential chocolate benefits

A recent study suggests that flavanol-rich cocoa drinks can significantly improve blood vessel function in smokers, potentially reducing the risk of cardiovascular disease. The researchers observed increases in nitric oxide levels and blood vessel responses after consumption of flavanol-rich drinks.
