Follicular helper Tcells (TFH cells), a rare type of immune cell that is essential for inducing a strong and lasting antibody response to viruses and other microbes, have garnered intense interest in recent years but the molecular signals that drive their differentiation had remained unclear. Now, a team of researchers at the La Jolla Institute for Allergy and Immunology has identified a pair of master regulators that control the fate of TFH cells.

Cancer Research UK scientists have for the first time identified that there are five distinct types of prostate cancer and found a way to distinguish between them, according to a study in EBioMedicine.
The findings could have important implications for how doctors treat prostate cancer in the future, by identifying tumours that are more likely to grow and spread aggressively through the body.
The researchers, from the Cancer Research UK Cambridge Institute and Addenbrooke's Hospital, studied samples of healthy and cancerous prostate tissue from more than 250 men.

Numerous genes that regulate the activity of a neurotransmitter in the brain have been found to be abundant in brain tissue of depressed females. This could be an underlying cause of the higher incidence of suicide among women, according to research at the University of Illinois at Chicago.
Studying postmortem tissue from brains of psychiatric patients, Monsheel Sodhi, assistant professor of pharmacy practice at UIC, noted that female patients with depression had abnormally high expression levels of many genes that regulate the glutamate system, which is widely distributed in the brain.

On the 70th anniversary of the atomic bombs in Hiroshima and Nagasaki, a three-part Series published in The Lancet looks at the enduring radiological and psychological impact of nuclear disasters, including the most recent accident at the Fukushima Daiichi nuclear power plant in Japan in 2011. The Series provides vital information for the public health planning of future disasters to protect the millions of people who live in areas surrounding the 437 nuclear power plants that are in operation worldwide.

In patients with chronic kidney disease (CKD), atherosclerosis is exceedingly common and contributes to the development of heart disease, which is the leading cause of death in this group. New research suggests that an organic byproduct generated by intestinal bacteria may be responsible for the formation of cholesterol plaques in the arteries of individuals with decreased kidney function.

Following the BMA's call for a 20% sugar tax to subsidise the cost of fruit and vegetables, experts in The BMJ this week debate whether a sugar tax could help combat obesity.
Sirpa Sarlio-Lähteenkorva, adviser at the Ministry of Social Affairs and Health in Finland, says that a specific tax on sugar would reduce consumption. "Increasing evidence suggests that taxes on soft drinks, sugar, and snacks can change diets and improve health, especially in lower socioeconomic groups," she writes.

Recent research has shown that racial segregation in the U.S. is declining between neighborhoods, and sociologists have been scrambling to find new ways to see discrimination. They believe that have found it, in micro-segregation, like when gay people complain that straight people move into their neighborhoods, or when suburban communities are separate from other communities and think they are better because of things like schools.

U.S. farmers have long hoped to extend sugarcane's growing range northward from the Gulf coast, substantially increasing the land available for sugar and biofuels. Several hybrid canes developed in the 1980s have proved hardy in cooler climes, surviving overwinter as far north as Booneville, Arkansas. But until now, no one had tested whether these "miscanes," as they are called, actually photosynthesize, and thus continue to grow, when the thermometer dips.
