Tasmanian devil research could help tackle immunotherapy resistance
A cluster of interacting proteins that are active in both human cancers and Tasmanian devil facial tumours, may give clues to how cancers evade the immune system, according to a new study.
Read moreHow neural circuits drive hungry individuals to peak performance
Success is no accident: To reach your goal you need perseverance. But where does the motivation come from? Scientists have now identified the neural circuit in the brain of fruit flies which makes them perform at their best when searching for food.

In the quest for a more youthful appearance, many people slather ointments on their skin or undergo injections of dermal fillers. But topical treatments often aren't very effective because they don't penetrate deep within the skin, whereas the results from injections typically last for only a few months and can be painful. Now, researchers have developed a needle-free 'exosome' treatment that reduces wrinkles in UV-exposed mice.

Researchers have identified two key proteins, ASC and NLRP3, in the maintenance of the innate immune homeostasis in the airway. These proteins do so by a caspase-1-independent mechanism, suggesting that there may be multiple mechanisms involved in protection against microbial infections.
Read more'Report card' on diet trends: Low-quality carbs account for 42 percent of a day's calories
An 18-year 'report card' on the American diet shows adults are eating too many low-quality carbohydrates and more than the recommended daily amount of saturated fat.
Read moreBoosting daily nut consumption linked to less weight gain and lower obesity risk
Increasing nut consumption by just half a serving (14 g or ½ oz) a day is linked to less weight gain and a lower risk of obesity, suggests a large, long term observational study.
Read moreOnion and garlic consumption may reduce breast cancer risk
In the first population-based study to examine the association between onion and garlic consumption and breast cancer in Puerto Rico, researchers found that women who ate sofrito more than once per day had a 67% decreased breast cancer risk.

A novel vaccine protected almost all mice and guinea pigs exposed to a new herpes virus. This may lead to the vaccine being tested in human studies.
Read moreChild's gluten intake during infancy, rather than mother's during pregnancy, linked to increased risk of developing type 1 diabetes
New research shows that a child's intake of gluten at age 18 months is associated with a 46% increased risk of developing type 1 diabetes for each extra 10g of gluten consumed.
