UCLA researchers show the potential of their digital health platform to help treat acute lymphoblastic leukemia by being able to personalize drug dosages and combinations
A major challenge in truly targeted cancer therapy is cancer’s suppression of the immune system. Northwestern University synthetic biologists now have developed a general method for “rewiring” immune cells to flip this action around. When cancer is present, molecules secreted at tumor sites render many immune cells inactive. The Northwestern researchers genetically engineered human immune cells to sense the tumor-derived molecules in the immediate environment and to respond by becoming more active, not less.
Johns Hopkins investigators report that their analysis of a national database representing more than 1 billion emergency department visits shows that over a recent eight-year period, nothing much has changed in the rates of unsuccessful suicide attempts, or in the age, gender, seasonal timing or means used by those who tried to take their lives in the United States.
In a small double-blind study, Johns Hopkins researchers report that a substantial majority of people suffering cancer-related anxiety or depression found considerable relief for up to six months from a single large dose of psilocybin -- the active compound in hallucinogenic "magic mushrooms."
A defect in a gene that produces dopamine in the brain appears to accelerate the onset of Parkinson’s disease, according to new research from Iowa State University. The effect is particularly dramatic for young-to-middle-age adults.
Lack of paid leave and outdated maternity care are barriers to breastfeeding that disproportionately impact families of color. This is the first study to show how these disparities translate into differences in health outcomes.
A team of neuroscience and biochemistry researchers at Stony Brook University have made a novel discovery that illustrates for the first time the difference between amyloid buildup in brain blood vessels and amyloid buildup around brain neurons.
• Individuals who took proton pump inhibitors or histamine receptor-2 blockers for heartburn, acid reflux, or ulcers had elevated risks of developing kidney stones. • In individuals without acute kidney injury, proton pump inhibitors were linked with a higher risk of developing chronic kidney disease or kidney failure compared with histamine receptor-2 blockers. • Research that uncovered these findings will be presented at ASN Kidney Week 2016 November 15–20 at McCormick Place in Chicago, IL.
The average age of a woman giving birth for the first time has risen dramatically in the United States over the past 40 years, driven by factors like education or career. A new study by researchers at University of California San Diego School of Medicine found that women choosing to become first-time mothers later in life may increase their chances of living into their 90s.

Emulsifiers, which are added to most processed foods to aid texture and extend shelf life, can alter intestinal bacteria in a manner that promotes intestinal inflammation and colorectal cancer, according to a new study.
B12 deficiency during pregnancy may predispose children to metabolic problems such as type-2 diabetes, according to research presented today at the Society for Endocrinology’s annual Conference in Brighton. These findings could lead to a review of current vitamin B12 requirements for pregnant women, whether through an improved diet or supplements.
For millennia, philosophers have struggled to define human consciousness. Now, a team of researchers led by neurologists at Beth Israel Deaconess Medical Center (BIDMC) has pinpointed the regions of the brain that may play a role maintaining it. Their findings, which have already garnered multiple awards from the American Academy of Neurology, were published today in that society’s journal, Neurology.
Researchers found that rodents that had been exposed to stress had a weakened alcohol-induced dopamine response and voluntarily drank more alcohol compared to controls. The blunted dopamine signaling to ethanol arose due to changes in the circuitry in the ventral tegmental area, the heart of the brain's reward system.
Researchers have developed a chemical compound that detects the Alzheimer’s protein amyloid beta better than current FDA-approved agents. The compound potentially could be used in brain scans to identify the signs of Alzheimer’s early, or to monitor response to treatment.
Men can take birth control shots to prevent pregnancy in their female partners, according to a new study published in the Endocrine Society’s Journal of Clinical Endocrinology & Metabolism.
Acute myeloid leukemia (AML) is an aggressive cancer known for drug resistance and relapse. In an effort to uncover new treatment strategies, researchers at University of California San Diego School of Medicine and Moores Cancer Center discovered that a cell surface molecule known as CD98 promotes AML. The study also shows that inhibiting CD98 with the therapeutic antibody IGN523 blocks AML growth in patient-derived cells and mouse models.
A robotic arm and a virtual game were essential tools in a new study from researchers at Johns Hopkins Medicine. The study results suggest that while training doesn't change neurological repair in chronic stroke patients, it can indeed help such patients learn new motor skills and achieve more independence in their daily lives.
