Reporting results from a first-in-human phase I clinical trial, researchers at University of California San Diego School of Medicine have found that treatment with cirmtuzumab, an experimental monoclonal antibody-based drug, measurably inhibited the “stemness” of chronic lymphocytic leukemia cancer (CLL) cells — their ability to self-renew and resist terminal differentiation and senescence.
A new study shows a rapid rise in the percentage of hospitals that require their workers to be vaccinated against influenza – except among hospitals that focus on treating the nation’s military veterans. The percentage of Veterans Affairs hospitals that have a flu vaccine mandate rose from 1 percent in 2013 to 4 percent in 2017. But at the same time, the percentage of non-VA hospitals requiring shots rose from 44 percent to nearly 70 percent.

Child care, parenting and child health/health care are important factors in improving the lives of children in low-income families, according to a new study from the Brown School at Washington University in St. Louis. Researchers conducted a national survey of staff at helplines where consumers dial 211 for community information and referral services.
As the first step toward predicting cerebral palsy in premature infants, scientists have identified a panel of microRNAs that are changed in babies who later develop abnormal muscle tone. MicroRNAs are small, noncoding RNA molecules that are important regulators of gene expression affecting developmental processes. Searching for microRNAs that could serve as early biomarkers – biological signs of disease – scientists for the first time have demonstrated that it is feasible to evaluate over 750 microRNAs using only one-half milliliter of blood collected from babies weighing less than 1500 grams (or under three pounds). Results were published in Physical Medicine and Rehabilitation – International.
UPTON, NY—If you want to understand how a material changes from one atomic-level configuration to another, it’s not enough to capture snapshots of before-and-after structures. It’d be better to track details of the transition as it happens. Same goes for studying catalysts, materials that speed up chemical reactions by bringing key ingredients together; the crucial action is often triggered by subtle atomic-scale shifts at intermediate stages.
A new study led by David Broniatowski, an assistant professor in the George Washington University’s department of engineering management and systems engineering, finds the “Why not take a risk?” mentality is widespread among patients and medical care providers.
New research from the University of Georgia suggests that fun can motivate kids to try new foods at lunchtime and ultimately eat more fruits and vegetables.
Menopause symptoms are not just for midlife anymore, according to a new Mayo Clinic study published this month in the Journal of the North American Menopause Society.

A new approach pioneered at the University of Pennsylvania’s Abramson Cancer Center may provide a new path towards treating Acute Myeloid Leukemia (AML) with CAR T cells.
A Ludwig Cancer Research study has uncovered an entirely novel mechanism by which cells enter a state of dormancy as tissues starved of oxygen become increasingly acidic. The study, led by Chi Van Dang, scientific director of the Ludwig Institute for Cancer Research, has potentially significant implications for cancer therapy: Large swaths of solid tumors are often deprived of oxygen, and cells in such patches are thought to be a major source of drug resistance and disease relapses.
Researchers funded by the National Eye Institute (NEI) have identified 133 genetic variants that predict with 75-percent accuracy a person’s risk for developing glaucoma related to elevated pressure within the eye. Future genetic tests could identify high-risk individuals who would benefit from early interventions aimed at preventing vision loss from glaucoma, a leading cause of vision loss and blindness in the United States.

Forward-thinking scientists in the 1970s suggested that circuits could be built using molecules instead of wires, and over the past decades that technology has become reality. The trouble is, some molecules have particularly complex interactions that make it hard to predict which of them might be good at serving as miniature circuits. But a new paper by two University of Chicago chemists presents an innovative method that cuts computational costs and improves accuracy by calculating interactions between pairs of electrons and extrapolating those to the rest of the molecule.
A strong social network could be the key to preserving memory. New research from The Ohio State University found that mice housed in groups had better memories and healthier brains than animals that lived in pairs.
