We all start out as a clump of identical cells. As these cells divide and multiply, they gradually take on distinct identities, acquiring the traits necessary to form, for instance, muscle tissue, bone, or nerves. A recent study from Rockefeller scientists offers new insight into how these cellular identities are […]

People with autoimmune diseases such as psoriasis, lupus and rheumatoid arthritis are at high risk of developing cardiovascular disease, even though none of these conditions seem to target the cardiovascular system directly. Now, researchers at Washington University School of Medicine in St. Louis believe they have begun to understand the […]

Newborn breastfed babies’ saliva combines with breastmilk to release antibacterial compounds that help to shape the bacterial communities (microbiota) in babies’ mouths, biomedical scientists have found. A study led by Dr Emma Sweeney and Adjunct Associate Professor Christine Knox, from QUT’s Institute of Health and Biomedical Innovation, with colleagues at the […]

Scientists have made a major discovery that shines a new, explanatory light on the link between obesity and cancer.

Researchers can design the perfect molecule to edit a gene, treat cancer or guide the development of a stem cell, but none of that will matter in the end if they can’t get their molecule into the human cells they want to manipulate. The solution to that problem, described in […]

Skeletal stem cells are valuable because it’s thought they can heal many types of bone injury, but they’re difficult to find because researchers don’t know exactly what they look like or where they live. Researchers at the University of Michigan have identified a type of skeletal stem cell in the […]

Lung cancer is among the most frequently occurring forms of cancer, second only to prostate cancer in men and breast cancer in women. It’s also the most lethal cancer type, claiming the lives of more adults than colon, breast and prostate cancer combined. About 8 in 10 lung cancer cases […]

Ovarian cancer claims the highest mortality rate of all gynecologic cancers – as high as 70 percent – in part because the disease is rarely detected earlier than stage 3 or 4. When the disease is discovered early in its development, however, survival rates are high. An effective screening technique […]

New Vanderbilt research finds how long humans and other warm-blooded animals live—and when they reach sexual maturity—may have more to do with their brain than their body. More specifically, it is not animals with larger bodies or slower metabolic rates that live longer; it is animals with more neurons in […]
