Intimate partner violence (IPV) disproportionately impacts women and younger populations, with incidences peaking between adolescence and young adulthood. Alarmingly, a strong correlation exists between IPV experienced in adolescence and its persistence into adulthood. Radiologists can play a key role in identifying physical signs of IPV, since specific fracture patterns detected in imaging have been shown to be predictive of abuse in children and adults. However, limited information is available about injury patterns in IPV-exposed adolescents and emerging adults despite their vulnerability. In a recent study, researchers from Brigham and ...

AMHERST, Mass. – There is a surprising dearth of research about how breast cancer cells can go dormant, spread and then resurface years or even decades later, according to a new review of in vitro breast cancer studies conducted by researchers at the University of Massachusetts Amherst.     “[Our review found that] less than 1% of all these studies that combine cells with designer environments look at dormancy,” says Shelly Peyton, Provost Professor of Chemical Engineering. “It’s ...

Texans have long endured scorching summer temperatures, so a global warming increase of about 3 degrees Fahrenheit (1.5 Celsius) might not sound like much to worry about. But a new study concludes that the heat index — essentially how hot it really feels — has increased much faster in Texas than has the measured temperature: about three times faster. That means that on some extreme days, what the temperature feels like is between 8 and 11 F (5 to 6 C) hotter than it would without climate change. The study, using ...

Research Highlights: Three independent, preliminary research studies have found that new Type 2 diabetes and weight-loss medications are often not prescribed or provided to patients as needed. One study of adults who had insurance covering the cost of obesity medications found that their likelihood of being prescribed the medications differed based on racial, demographic and medical factors. A second study determined that not all patients with Type 2 diabetes were equally likely to use the newest medications. A ...

Boston, MA – In the first national estimate of county-level disparities in heat-related emergencies, a new study led by investigators from the Harvard Pilgrim Health Care Institute found that vulnerable communities were at high risk. The study, “County-Level Disparities in Heat-Related Emergencies,” was published in the March 19 edition of JAMA Network Open.

(MEMPHIS, Tenn. – March 19, 2024) Fibrolamellar carcinoma (FLC) is a rare liver cancer with a poor prognosis if not addressed early with surgery. The disease is caused by a single genetic mutation that creates a fusion protein. Scientists at St. Jude Children’s Research Hospital and The University of Tennessee Health Science Center discovered an immune cell protein that can target and spark the destruction of FLC. Scientists found naturally occurring T cells in a patient with FLC were uniquely capable of recognizing the fusion protein. These cells provide ...

From solar panels on our roofs to the new OLED TV screens, many everyday electronic devices simply wouldn’t work without the interaction between light and the materials that make up semiconductors. A new category of semiconductors is based on organic molecules, which largely consist of carbon, such as buckminsterfullerene. The way organic semiconductors work is largely determined by their behaviour in the first few moments after light excites electrons, forming “excitons” in the material. Researchers from the Universities of Göttingen, Graz, ...

Genetic diversity of the malaria parasite in pregnant women and children declined in an area targeted for malaria elimination in Mozambique, according to a study led by the Barcelona Institute for Global Health (ISGlobal), a centre supported by “la Caixa” Foundation and the Manhiça Health Research Centre (CISM).

In the most comprehensive genetic study of the people living in the Eastern Highlands of Papua New Guinea to date, researchers from Papua New Guinea and the U.K. revealed the complex population structure and migration patterns of the communities in the region. The results, published March 19 in The American Journal of Human Genetics, lay the foundation for future research on the fatal disease kuru—a disease transmitted during traditional anthropophagic mortuary practices— that devastated the area in the 20th century. “We navigated one of the most complex landscapes possible in terms of geographical, cultural and linguistic diversity and set the scene ...

The middle-aged brain could provide a window into future cognitive health, researchers write in a review publishing March 19 in the journal Trends in Neurosciences. The team reviewed evidence from human and animal studies suggesting that middle age—commonly considered as the period between 40 and 60 or 65 years of age—marks a shift in brain aging. They argue that more research should be dedicated to middle age, a period of life that is historically understudied. “Middle age is associated with specific and modifiable risk factors for future dementia risk,” write the authors, who include neuroscientist Yvonne Nolan ...
