Scientists say they have discovered a potential new target for immunotherapy of malignant brain tumors, which so far have resisted the ground-breaking cancer treatment based on harnessing the body’s immune system. Study of T cells from glioma tumors identifies a pathway that inhibits immune response. Blocking the pathway in an animal model stimulated T cell killing of brain tumor cells. The inhibitory pathway was also found in several other cancer types.

Recreational drinking, smoking, and drug use is linked to premature heart disease in young people, particularly younger women, finds research. Those who regularly use 4 or more substances are 9 times as likely to be affected, the findings indicate.

Researchers have invented a new type of amputation surgery that can help amputees to better control their residual muscles and sense where their “phantom limb” is in space. This restored sense of proprioception should translate to better control of prosthetic limbs, as well as a reduction of limb pain, the researchers say.

Coffee, cola or an energy drink: caffeine is the world’s most widely consumed psychoactive substance. Researchers have now shown in a study that regular caffeine intake can change the gray matter of the brain. However, the effect appears to be temporary.

In a study, researchers report that they developed a deep learning model that, in certain conditions, was more than 71% accurate in predicting survival expectancy of lung cancer patients, significantly better than traditional machine learning models that the team tested. The other machine learning models the team tested had about a 61% accuracy rate.

A leading cause of SCD in young athletes is arrhythmogenic cardiomyopathy (ACM), a genetic disease in which healthy heart muscle is replaced over time by scar tissue (fibrosis) and fat. Researchers have now developed a better understanding of the pathological characteristics behind the disease, as well as promising avenues for prevention.

The brain’s neural activity is irregular, changing from one moment to the next. To date, this apparent “noise” has been thought to be due to random natural variations or measurement error. However, researchers have shown that this neural variability may provide a unique window into brain function. In a new article, the authors argue that researchers need to focus more on neural variability to fully understand how behavior emerges from the brain.

Scientists used accelerometers to track daily activity levels for a week in 89 adults with obesity or overweight and, in a series of tests, measured their ability to multitask and maintain their attention despite distractions. The study revealed that individuals who spent more sedentary time in bouts lasting 20 minutes or more were less able to overcome distractions.

Almost one in five people lacks the protein α-actinin-3 in their muscle fibre. Researchers now show that more of the skeletal muscle of these individuals comprises slow-twitch muscle fibres, which are more durable and energy-efficient and provide better tolerance to low temperatures than fast-twitch muscle fibres.

In a world first genetic study, researchers found that that long-term, heavy coffee consumption – six or more cups a day – can increase the amount of lipids (fats) in your blood to significantly heighten your risk of cardiovascular disease (CVD). Importantly, this correlation is both positive and dose-dependent, meaning that the more coffee you drink, the greater the risk of CVD.

Boys who regularly play video games at age 11 are less likely to develop depressive symptoms three years later, finds a new study. The study also found that girls who spend more time on social media appear to develop more depressive symptoms. Taken together, the findings demonstrate how different types of screen time can positively or negatively influence young people’s mental health, and may also impact boys and girls differently.
