Anxiety may be an early sign of Alzheimer's

Anxiety disorders are common across the United States, thought to affect around 40 million adults each year. However, as if these feelings of worry and fear aren't enough to contend with, a new study suggests that older people who have worsening anxiety symptoms may be more likely to develop Alzheimer's disease. Researchers found that increasing symptoms of anxiety were linked to higher levels of beta-amyloid, which is a protein associated with Alzheimer's disease, in the brains of older people with normal cognitive functioning.

Could Vitamin C Help Fight Tuberculosis?

A new study suggests that a low-cost nutrient could help drugs fight tuberculosis more effectively. The study found that anti-tuberculosis drugs killed more bacteria in laboratory mice when the mice received vitamin C. The authors say the findings could offer a low-cost, safe way to reduce the long treatment time for one of the world's deadliest diseases. They also say the vitamin supplement could offer a way to fight tuberculosis that is resistant to antibiotic drugs.

Flu may be spread just by breathing

It is easier to spread the influenza virus (flu) than previously thought, according to a new study. People commonly believe that they can catch the flu by exposure to droplets from an infected person's coughs or sneezes or by touching contaminated surfaces. But, new information about flu transmission reveals that we may pass the flu to others just by breathing.
