Exposure to trauma is increasingly common among school-aged American students, yet many affected children are not receiving the mental health care that could enable them to heal and thrive. Schools are the most common source of mental health care for students, which is why school administrators, counselors and teachers need the tools to enable them to develop an environment that promotes evidence-based interventions to help students overcome trauma and excel.

For the first time, an international team of scientists, led by researchers at University of California San Diego School of Medicine, have determined that an Alzheimer’s disease (AD) polygenic risk score can be used to correctly identify adults with mild cognitive impairment (MCI) who were only in their 50s. MCI is considered a precursor to AD.

A new study by UCSF Benioff Children's Hospital Oakland researcher Dr. June Tester examined national data on preschool-aged children from 1999 to 2014 to highlight characteristics of children with the highest degree of obesity and found a strong correlation between the amount of “screen time” these children are exposed to and the likelihood of them being severely obese. The study also found that preschoolers with severe obesity are also more likely to be of an ethnic or racial minority and more likely to be living in poverty.

UC San Diego School of Medicine researchers developed a visible neural network and used it to build DCell, a virtual model of a functioning brewer’s yeast cell. To do this, they amassed all knowledge of cell biology in one place and created a hierarchy of these cellular components. Then they mapped standard machine learning algorithms to this knowledgebase. DCell can be viewed at d-cell.ucsd.edu. The technical details are published March 5 in Nature Methods.

In the first study to measure the link between an employee’s number of paid sick leave days and the use of vital preventive health care services like getting a flu shot, researchers found a 26 to 85 percent increase in preventive health care use among those with at least 10 or more paid sick leave days. For the female-focused preventive services, they showed a 55 percent increase in the use of preventive mammography.

A genetics research team at Johns Hopkins Medicine has solved a dilemma facing researchers who use genomewide association studies (GWAS) by developing a new approach that strategically “filters” which genes are worth further study. The researchers hope this strategy will accelerate the study of diseases such as Parkinson’s, Alzheimer’s, schizophrenia and even addiction by helping researchers avoid “dead-end paths.” They are optimistic that this strategy will gain widespread use and will save researchers time and money.

A study of more than 200,000 Medicare patients who had common surgical procedures shows that, compared to the general population, they underwent far fewer minimally invasive operations, whose benefits include lower rates of complications and readmissions, along with shorter hospital stays.

Columbia Engineers are the first to miniaturize dual-frequency combs by putting two frequency comb generators on a single millimeter-sized silicon-based chip. This could lead to low-cost, portable sensing and spectroscopy in the field in real-time. “This is the first time a dual comb has been generated on a single chip using a single laser,” says Electrical Engineering Prof. Michal Lipson who led the team with Applied Physics Prof. Alexander Gaeta.
