Have months of self-isolation, lockdown and working from home irrevocably changed what we will put on once we go out again? For a long time, the assumption was yes. Now, as restrictions ease and the opening up of offices and travel is dangled like a promise, that expectation is more like a qualified “maybe.” But…
A new paper in the Review of Economic Studies indicates that disease can alter the social networks and economic growth of countries for generations, even after the disease itself is eradicated. Social networks are an important determinant of a country’s growth as they affect the diffusion of ideas and the rate of technological progress. But…
An estimated 334,000 COVID-19 cases are attributable to meatpacking plants, resulting in $11.2 billion in economic damage, according to a new study led by a researcher at the University of California, Davis. The study was published in the journal Food Policy. It found that beef- and pork-processing plants more than doubled per capita infection rates…
Philadelphia, April 15, 2021 – A new study shows that markers of fear recall differ between men and women, but in a hormone-dependent manner. Aberrant fear-memory processing in the brain is thought to underlie anxiety disorders, which affect hundreds of millions of people worldwide. The neurobiological mechanisms underlying these disorders remain poorly understood, but recent…
Fifty-five years ago, America’s death toll from automobile crashes was sky-high. Nearly 50,000 people died every year from motor vehicle crashes, at a time when the nation’s population was much smaller than today. But with help from data generated by legions of researchers, the country’s policymakers and industry made changes that brought the number killed…
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…
