Socioeconomic disadvantage, long-term outcomes after heart attack
What The Study Did: Registry data were used to examine the association between living in a socioeconomically disadvantaged area and long-term survival among patients who had their first heart attack at or before age 50.

Study finds worse outcomes for heart attack survivors living in disadvantaged neighborhoods
Researchers found that even after adjusting for other health risk factors, neighborhood-level socioeconomic disadvantage was associated with a 57 percent higher rate of cardiovascular mortality over an approximate 11-year follow-up period.

Heavy metal vapors unexpectedly found in comets throughout our Solar System -- and beyond
A new study by a Belgian team using data from the European Southern Observatory's Very Large Telescope has shown that iron and nickel exist in the atmospheres of comets throughout our Solar System, even those far from the Sun. A separate study by a Polish team, who also used ESO data, reported that nickel vapor is also present in the icy interstellar comet 2I/Borisov. This is the first time heavy metals have been found in the cold atmospheres of distant comets.

Protein simulation, experiments unveil clues on origins of Parkinson's disease
Parkinson's disease is the second most common neurodegenerative disease and affects more than 10 million people around the world. To better understand the origins of the disease, researchers from Penn State College of Medicine and The Hebrew University of Jerusalem have developed an integrative approach, combining experimental and computational methods, to understand how individual proteins may form harmful aggregates, or groupings, that are known to contribute to the development of the disease.

'Postcode lottery' of nutrient intake from crops revealed in new study
The amount of nutrients people get from the crops that they eat is a type of 'postcode lottery', according to new research that has analysed thousands of cereal grains and soils as part of a project to tackle hidden hunger in Malawi and Ethiopia.

Researchers estimate COVID-19-positive rate in Stockholm during first year of pandemic
By the end of the first year of the pandemic in metropolitan Stockholm, investigators estimate that one-fifth of adults in the region previously had COVID-19. The findings, which are published in the Journal of Internal Medicine, come from analyses of anti-viral antibody responses in healthy blood donors and pregnant women.

What are the effects of inappropriate prescriptions in older adults?
Individuals are often prescribed increasing numbers of medications as they age, and while many of these prescriptions are justifiable, some may be inappropriate. A recent analysis published in the British Journal of Clinical Pharmacology examined the results of all studies investigating associations between potentially inappropriate prescribing--which includes prescribing medications that may not produce benefits relative to harm and not prescribing medications that are recommended--and outcomes of older adults.

COVID-19 pandemic has created the "perfect storm" for family violence
In an article published in the International Journal of Mental Health Nursing, experts stress that the COVID-19 pandemic presents the "perfect storm" for family violence, where a set of rare circumstances have combined to aggravate intimate partner violence, domestic abuse, domestic violence, and child abuse.

Alzheimer protein APP regulates learning and social behavior in the healthy brain
The APP protein is known for its role in Alzheimer's disease, but its contribution to healthy brain function remains largely unexplored. Using a mouse model, a research team led by Heidelberg scientists gained new insights on the physiological functions of the APP protein family. The absence of APP during brain development was shown to result in malformations of brain regions implicated in learning and memory, severely impairing learning in the mice and causing autistic-like behaviour.

Magnetically propelled cilia power climbing soft robots and microfluidic pumps (video)
The rhythmic motions of hair-like cilia move liquids around cells or propel the cells themselves. In nature, cilia flap independently, and mimicking these movements with artificial materials requires complex mechanisms. Now, researchers reporting in ACS Applied Materials & Interfaces have made artificial cilia that move in a wave-like fashion when a rotating magnetic field is applied, making them suitable for versatile, climbing soft robots and microfluidic devices.

Study examines young athletes' knee health after returning to sport following ACL reconstruction
One-quarter to one-third of young, active patients who undergo anterior cruciate ligament reconstruction experience a second ACL injury after they return to sport (RTS). New research indicates that young athletes who feel confident about their knee health at the time of medical clearance for sports participation after ACL surgery have a higher likelihood of meeting all RTS criteria related to physical function but also have a higher likelihood of experiencing a second ACL injury within 2 years after RTS.

New expert statement confirms strong links between our hormones and COVID-19
New expert statement confirms strong links between our hormones and COVID-19: The endocrine system is strongly involved in SARS-Cov-2 infection - so much so that evidence of an "endocrine phenotype" of COVID-19 has emerged, according to a statement by the European Society of Endocrinology (ESE) published in the journal Endocrine in April 2021.

Modeling can predict mutation "hotspots" and antibody escapers in SARS-CoV-2 spike protein
A new study from the Centers for Genomics and Systems Biology at New York University and NYU Abu Dhabi uses computational modeling to assess the biological significance of spike protein mutations, uncovering versions of the virus that bind more tightly or resist antibodies and offering a promising public health surveillance tool.

Research team develops new class of soft materials
Scientists at UVA's School of Engineering have developed a novel elastomer that is very stretchable and 10,000 times softer than a conventional rubber. It can be 3D printed for use in health care. The team, led by Assistant Professor Liheng Cai, collaborated with beamline scientists at Brookhaven National Laboratory to reveal the inner makeup of the printed materials without damaging the samples. Their research is published as a cover article in Chemistry of Materials.
