A drug-resistant bug that can cause chronic and severe lung infections in patients with cystic fibrosis (CF) is spreading worldwide and becoming gradually more virulent, researchers reported in the journal Science.

The bug, called Mycobacterium abscessus, is typically found in water, soil and dust. Previously, it was thought to be independently acquired by people through contact with the environment. But, the new study revealed that the majority of M. abscessus infections are spreading from one patient to another in clinical settings.

A small-scale study conducted by Cambridge researchers has shown a link between overeating and poorer episodic memory. Researchers do not try to show that overweight people are more forgetful, but want to suggest that incomplete or unformed memories of earlier meals may lead to overeating.

There are many prostate cancer tests available in the market, but a new research has found that these tests fail to accurately reveal the severity of the disease in as many as 50% of the cases. This has led researchers from the University of Cambridge to call for better tests to define the nature of the cancer.
