Using a two-photon imaging microscope and a wealth of genetic tools, researchers from Cold […]

Lamprey is blood-sucking vampire-like fish that attach to and eventually kill game fish, making them the bane of many a fisherman's existences. Like something out of a horror film, these parasites use radial rows of sharp teeth to dig into the skin of their host and extract blood and other […]

Mitochondria, often thought of as the powerhouses of cells, are just one part of a larger living thing, but they are unique among cellular structures in that they have their own DNA that is distinct from that of their parent cells. And just like their parent cells, mitochondria need quality-control […]

NIH-funded study finds higher risks for children of women who took efavirenz during pregnancy. Children born to women on HIV therapy containing the drug efavirenz were 2 to 2.5 times more likely to have microcephaly, or small head size, compared to children born to women on regimens of other antiretroviral […]

Women who are diagnosed with peripartum cardiomyopathy (PPCM) during late pregnancy or within a month following delivery are more likely to experience restored cardiac function and improved outcomes compared to those who are diagnosed later in the postpartum period, according to a new study from Penn Medicine. The findings underscore the […]

One day in the future when you need medical care, someone will examine you, diagnose the problem, remove some of your body’s healthy cells, and then use them to grow a cure for your ailment. The therapy will be personalized and especially attuned to you and your body, your genes, […]

A new Yale study shows that some patients being treated for severe heart failure with a battery-operated pump saw significant improvement after additionally using neurohormonal blockade (NHB) drug therapy. NHB therapy, which includes three broad categories of drugs, including ACE inhibitors, has long been the standard therapy for treating heart […]

Uterine fibroids are a very common condition, and affected women often wonder if their pregnancy challenges are related to their fibroids. In this article, we discuss the ‘classic’ view on how fibroids can affect fertility, and the effects of different fibroid treatment options on fertility. Fibroids It is estimated that […]

Scientists are still grappling with questions as fundamental as how a cell actually grows. Cells are not just water-filled blobs but are chock-full of proteins, nucleic acids, lipids, and many other types of molecules. When a cell grows, it not only increases in size, it also has to make more […]
