Researchers from King’s College London have created 3D replicas of full-sized healthy adult hearts from Computed Tomography (CT) images and analyzed how cardiac shape relates to function. Published today in PLOS Computational Biology, the study also includes 1000 new synthetic hearts that have been made open access allowing researchers to download and use them…
From cancer treatment to sunlight, radiation and toxins can severely damage DNA in both harmful and healthy cells. While the body has evolved to efficiently treat and restore damaged cells, the mechanisms that allow this natural repair remain misunderstood. In a new study, Northwestern University researchers have used cryogenic electron microscopy (cryo-EM) to visualize this…
The complex patterns of genetic ancestry uncovered from genomic data in health care systems can provide valuable insights into both genetic and environmental factors underlying many common and rare diseases–insights that are far more targeted and specific than those derived from traditional ethnic or racial labels like Hispanic or Black, according to a team of…
Engaging in household chores may be beneficial for brain health in older adults. In a recent Baycrest study, older adults who spent more time on household chores showed greater brain size, which is a strong predictor of cognitive health. “Scientists already know that exercise has a positive impact on the brain, but our study is…
PHILADELPHIA–People who have recovered from COVID-19 had a robust antibody response after the first mRNA vaccine dose, but little immune benefit after the second dose, according to new research from the Penn Institute of Immunology. The findings, published today in Science Immunology, suggest only a single vaccine dose may be needed to produce a sufficient…
PHILADELPHIA, Thursday, April 15, 2021 — The American College of Physicians (ACP), publisher of Annals of Internal Medicine (Annals), one of the most influential peer-reviewed clinical journals in the world, and the American Heart Association (AHA) today announce a new partnership to jointly publish Annals of Internal Medicine: Clinical Cases (AIMCC). The digital, open access,…
In January 2020, just weeks after the first Covid-19 cases emerged in China, the full genome of the new coronavirus was published online. Using this genomic sequence, scientists scrambled to design a large assortment of diagnostic tests for the virus. But the virus has mutated since then. And as the coronavirus has evolved, so has…
“Right now, we believe these events to be extremely rare, but we are also not yet certain we have heard about all possible cases, as this syndrome may not be easily recognized as one associated with the vaccine,” Dr. Rochelle P. Walensky, the C.D.C. director, said at a White House news conference on the pandemic…
South Africa immediately copied the American pause on Johnson & Johnson vaccinations, infuriating doctors who are still clamoring for shots, especially in remote parts of the country. In February, health officials dropped the AstraZeneca vaccine over its limited efficacy against a dangerous variant there. To date, only half of 1 percent of the population is…
With all American adults soon to be eligible for Covid-19 vaccines and businesses and international borders reopening, a fierce debate has kicked off across the United States over whether a digital health certificate (often and somewhat misleadingly called a “vaccine passport”) should be required to prove immunization status. Currently, Americans are issued a white paper…
