When the blood supply is low, cancer cells can use lipid molecules as fuel instead of blood glucose. This has been shown in animal tumour models by researchers at Karolinska Institutet, Sweden, in a study published in Cell Metabolism. The mechanism may explain why tumours often develop resistance to cancer drugs that inhibit the formation of blood vessels. Tumour growth […]

Long-term and short-term relationships are obviously different from each other. Some people are the type you’d want to marry; others are good primarily for the sex.

The brain’s ability to form new neural connections, called neuroplasticity, is crucial to recovery from some types of brain injury, but this process is hard to study and remains poorly understood. A new study of neural circuit repair in the retina shows that neurons can make new connections to the right types of photoreceptors to restore selective connectivity after an […]

Researchers at the University of Southampton have developed a new computational way of analysing X-ray images of lungs, which could herald a breakthrough in the diagnosis and assessment of Chronic Obstructive Pulmonary Disease (COPD) and other lung diseases. A multi-disciplinary team of mathematicians, clinicians, and image specialists from three University of Southampton faculties has devised a method for numerically describing […]

In the 60’s and 70’s, there was a major smoking issue among adults.

For some people, particularly those who are elderly, even a light touch of the skin or contact with clothing can lead to unbearable itching. What’s worse, anti-itch treatments, including hydrocortisone, don’t provide much relief for this type of itching. Now, researchers at Washington University School of Medicine in St Louis have discovered, in mice, why a touch can cause such […]
