“We’re facing a tremendous epidemic with teen anxiety and depression, and we wanted to find an early marker that predicted the development of anxiety, depression and attentional symptoms,” said the study’s lead author, Susan Whitfield-Gabrieli. She’s a professor of psychology and director of the Northeastern University Biomedical Imaging Center, in Boston.

In a small sample of less than 100 children without known mental health concerns, the research team found that connections in certain areas of the brain seen at age 7 could help predict mental health concerns that developed four years later.

“The study could have great clinical implications,” Whitfield-Gabrieli said...

Exercise may play a role in reducing the growth of colon cancer cells according to new research published in The Journal of Physiology. The study found that after a short session of high intensity interval training (HIIT), growth of colon cancer cells was reduced, and this also increased indicators of inflammation.

For a long time, the focus on exercise has been on the positive changes in the body that occur following a longer period of training. However, these findings suggest that the effects following a single session of HIIT, an exercise regime involving short, high energy bursts are also important...

Rutgers researchers invent technology that could lead to wearable biosensors. Imagine wearing a device that continuously analyzes your sweat or blood for different types of biomarkers, such as proteins that show you may have breast cancer or lung cancer, exposure to dangerous bacteria, viruses and pollutants.

“This is really important in the context of personalized medicine or personalized health monitoring,” said Mehdi Javanmard, an assistant professor in the Department of Electrical and Computer Engineering at Rutgers University-New Brunswick...

Macronutrient content and characteristics of the dietary interventions

The 5-minute test measures biological markers in urine created by the breakdown of foods such as red meat, chicken, fish and fruit and vegetables. The analysis, developed by researchers from Imperial College London, Newcastle University and Aberystwyth University, also gives an indication of how much fat, sugar, fibre and protein a person has eaten. Although the work is at an early stage, the team hope that with future development the test will be able to track patients’ diets. It could even be used in weight loss programs to monitor food intake.

Evidence suggests people inaccurately record their own diets, and under-report unhealthy food while over-reporting fruit and vegetable intake – and that the likelihood of inacc...
