Researchers have discovered the reason why immune cells lose energy when they enter the solid tumor microenvironment -- and how to restore their energy levels. A metabolic enzyme, called Acetyl-CoA carboxylase, has been identified as the culprit, for it causes T cells to store fat, rather than burning fat for energy.

Researchers have discovered a link between gut bacteria and the success of milk-allergy oral immunotherapy. The study found that Bifidobacterium -- a genus of beneficial bacteria in the gut -- was associated with a higher chance of successful treatment. The finding may help in the development of more effective oral immunotherapies, perhaps by combining them with probiotic supplements.

A positive relationship with a teacher at an early age may help children to feel more engaged with school, but not necessarily in the long term, new research shows. A new study of more than 3,600 young people in Australia shows that their 'school engagement' -- their interest in school and willingness to learn -- fluctuates between ages eight and 15, especially during the transition between primary and secondary education.

Hunger can drive a motivational state that leads an animal to a successful pursuit of a goal -- foraging for and finding food. In a highly novel study, researchers describe how two major neuronal subpopulations in a part of the brain's thalamus called the paraventricular nucleus participate in the dynamic regulation of goal pursuits. This research provides insight into the mechanisms by which the brain tracks motivational states to shape instrumental actions.

Research has found a less expensive and easier to use test to learn more about forensic touch DNA. This research has important implications for forensic investigations and being able to identify DNA from a primary contact -- someone who may have committed the crime -- as well as secondary DNA that was inadvertently and indirectly transferred through touch.

It is known that large amounts of licorice cause high blood pressure. A new study now shows that even small amounts of licorice raise blood pressure. The individuals who react most strongly also show signs of strain on the heart.

Dartmouth researchers tracked more than 200 undergraduates for all four years of college to capture the most in-depth data yet on how students' self-esteem and mental health fluctuates during their years in academia. The researchers identify key populations and stressors they say administrators could target to improve student well-being. The study -- conducted from 2017 to 2022 -- also provides among the first real-time accounts of how the coronavirus pandemic affected students and resulted in long-lasting behavioral changes that persisted even as the pandemic diminished.
