Women who shared their mother’s womb with a male twin are less likely to graduate from high school or college, have earned less by their early 30s and have lower fertility and marriage rates when compared with twins who are both female, according to new Northwestern University research. In the […]

The U.S. Food and Drug Administration today approved Mayzent (siponimod) tablets to treat adults with relapsing forms of multiple sclerosis (MS), to include clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease. Billy Dunn, M.D., director of the Division of Neurology Products in the FDA’s Center for Drug Evaluation […]

Life can depend upon the interaction of two proteins that come together along a metabolic pathway. There, they enable growth by creating fatty acids essential for ensuring that cell membranes form in a protective, fluid environment. While scientists have understood the basic enzymes involved in this fatty-acid biosynthesis, they have […]

Protein Kinase C (PKC) enzymes are crucial for a number of cellular activities, including cell survival, proliferation and migration — functions that must be carefully controlled lest cells get out of control and form a tumor. Researchers at University of California San Diego School of Medicine found that another enzyme, […]

A discovery about how exercise improves brain function could be harnessed for research into ageing, and boosting learning and memory. An international team from The University of Queensland and the Dresden University of Technology has identified what triggers the boost to brain function through exercise. Dr Tara Walker from UQ’s Queensland Brain Institutesaid the improvements […]

In a paper recently published in the journal Nature Medicine, a group of researchers from Spain detail their study of the brains of deceased people, indicating that our “neck-tops” are perfectly capable of growing brand new cells well into advanced age. This finding comes as somewhat of a surprise in […]

NASCAR has nothing on cancer cells when it comes to exploiting the power of drafting, letting someone else do the hard work of moving forward while you coast behind. Building on the relatively new discovery that metastatic cancer cells leave tumors and travel in clusters, not singles, a Vanderbilt University […]

Cells of the retinal pigment epithelium (RPE) form unique patterns that can be used to track changes in this important layer of tissue in the back of the eye, researchers at the National Eye Institute (NEI) have found. Using a combination of adaptive optics imaging and a fluorescent dye, the […]

A combination of two topical creams already shown to clear precancerous skin lesions from sun-damaged skin also lowers the risk that patients will later develop squamous cell carcinoma of the skin. The study, from Washington University School of Medicine in St. Louis, Massachusetts General Hospital and Harvard Medical School, appears […]

When it comes to March Madness, Cathy Goldstein, M.D., M.S., might have an edge over her fellow bracketologists. The neurologist at Michigan Medicine’s Sleep Disorders Centers combines her basketball fandom and sleep science expertise as she makes her selections. Below, she explains how circadian rhythm plays into her picks. What are circadian rhythms? Goldstein: Circadian […]

A protein that protects people with inflammatory bowel disease has quite a different effect in graft-vs.-host disease, a common and challenging side effect of bone marrow transplants. In a surprising finding, researchers at the University of Michigan Rogel Cancer Center showed the protein NLRP6 aggravated the difficult symptoms of gastrointestinal graft-vs.-host disease […]

According to the U.S. Centers for Disease Control and Prevention, about half of all Americans will have periodontal disease at some point in their lives. Characterized by inflamed gums and bone loss around teeth, the condition can cause bad breath, toothache, tender gums and, in severe cases, tooth loss. Now, […]
