Booth is publicly releasing two large scale neuroimaging datasets on reading and language development to support other researchers across the world who are working to understand how academic skills development in childhood. “We have been able to follow our curiosity and answer some really interesting questions […]

Studies that started in zebrafish have now pointed to a role for collagen secretion in a wide variety of clinical symptoms — and in a newly identified genetic syndrome. Ela Knapik, MD, associate professor of Medicine at Vanderbilt University Medical Center, and her colleagues discovered the syndrome caused by mutation […]

UK scientists have identified a new way to kill pancreatic cancer cells by ‘pulling the plug’ on the energy generator that fuels calcium pumps on their cell surface. The study, published in the British Journal of Cancer, reports how switching off the cancer’s energy supply causes the pancreatic cancer cells to […]

Epigenetic changes occur in the DNA of breast cancer cells that have developed a resistance to hormone therapy, an effective treatment for ER+ breast cancer, which accounts for 70% of all diagnoses. Reversing these changes, researchers say, has significant potential to help reduce breast cancer relapse. A team led by […]

A woman’s supply of eggs is finite, so it is crucial that the quality of their genetic material is ensured. New work from Carnegie’s Marla Tharp, Safia Malki, and Alex Bortvin elucidates a mechanism by which, even before birth, the body tries to eliminate egg cells of the poorest quality. […]

Genetic modification of babies in China one year ago was universally condemned. At the same time, CRISPR treatments are on their way into our clinics. Jacob Corn explains the difference. A huge outcry broke out a year ago when Chinese researcher He Jiankui announced at a conference that he had […]

Some plastic food and beverage containers still contain bisphenol A (BPA), which can mimic the hormone estrogen. Although experts say that small amounts of BPA detected in foods are unlikely to cause problems, some people worry that constant low-level exposures could have health effects, especially for developing fetuses, infants and […]

An organism's genome contains all of the information necessary for each of its cells and tissues to develop and function properly. Written in DNA, each individual gene encodes for something, whether it is a structural protein that helps define a tissue's shape, an enzyme that catalyzes the chemical reactions of […]

A stem cell transplant — also called a bone marrow transplant — is a common treatment for blood cancers, such as acute myeloid leukemia (AML). Such treatment can cure blood cancers but also can lead to life-threatening complications, including heart problems and graft-versus-host disease, in which new immune cells from […]

A new Penn Medicine study puts researchers within closer reach of vaccines that can protect infants against infections by overcoming a mother’s antibodies, which are known to shut down immune defenses initiated by conventional vaccines. That hurdle largely explains why vaccinations for infectious diseases like influenza and measles not given until […]

1 in 6 Children Loses Priority Points Due to Flawed Score System, UCSF Study Shows. Children waiting for new livers who are much smaller than their peers have a heightened risk of dying. Despite this, 40 percent of these undersized waitlisted children may lose vital points required to expedite transplantation, […]

A study published in the  New England Journal of Medicine suggests that erythropoietin treatment may not provide neuroprotection for extremely premature babies.

The researchers randomized more […]

A new prospective cohort study published last week in the journal SLEEP suggests that sleeping for 7 or more hours every night might not be all that it’s cracked up to be after all – at least when it comes to cognitive ability, gray matter volume, and white matter microstructure. […]

How do a couple of universally expressed proteins in stem cells and developing embryos influence an individual cell’s ultimate fate — whether it ultimately becomes, for example, a retinal cell, a heart muscle cell, or a stomach lining cell? That’s the question that Rajesh C. Rao, M.D., and his colleagues at […]

THERE’S NO SHORTAGE of ways to kill a cancer cell. Cut it out, poison it, blast it with radiation, shower it with killer immune cells—they all get the job done. But there is a shortage of good ways to kill cancer cells. One that knocks out all the bad cells in one swipe, […]

Lab-grown brain organoids developed from a patient’s own glioblastoma, the most aggressive and common form of brain cancer, may hold the answers on how to best treat it. A new study in Cell from researchers at Penn Medicine showed how glioblastoma organoids could serve as effective models to rapidly test personalized treatment […]
