About The Study: Survivors of adolescent and young adult cancer had high rates of perceiving increased infertility risk but frequently overestimated or underestimated their risk in this study that included 785 participants. These findings suggest that counseling on infertility risk throughout survivorship may reduce misalignment between perceptions and actual risk, decrease fertility-related psychological distress, and inform family planning decisions.  Authors: H. Irene Su, M.D., M.S.C.E., ...

Researchers have developed a method that can reveal the location of errors in quantum computers, making them up to ten times easier to correct. This will significantly accelerate progress towards large-scale quantum computers capable of tackling the world’s most challenging computational problems, the researchers said. Led by Princeton University’s Jeff Thompson, the team demonstrated a way to identify when errors occur in quantum computers more easily than ever before. This is a new direction for research ...

PHILADELPHIA – Women and those from racial and ethnic groups underrepresented in medicine (URiM) not only occupy few leadership roles in surgical departments but also tend to be clustered into certain leadership roles, according to a new analysis led by researchers from the Perelman School of Medicine at the University of Pennsylvania. These clusters of roles include vice chairs of diversity, equity, and inclusion (DEI) or wellness, where the promotion path to department chair is unclear. The report was published today in JAMA Surgery and led by ...

At a glance: New AI tool called EVEscape uses evolutionary and biological information to predict how a virus could change to escape the immune system.   The tool successfully predicted the most concerning new variants that occurred during the COVID-19 pandemic. Researchers say the tool can help inform the development of vaccines and therapies for SARS-CoV-2 and other rapidly mutating viruses. The COVID-19 pandemic seemed like a never-ending parade of SARS-CoV-2 variants, each equipped with new ways to evade the immune system, leaving the world bracing for what would come next. But what if there were a way to make predictions ...

Imagine researchers exploring a dark room with a flashlight, only able to clearly identify what falls within that single beam. When it comes to microbial communities, scientists have historically been unable to see beyond the beam — worse, they didn’t even know how big the room is. A new study published online October 11, 2023 in Nature highlights the vast array of functional diversity of microbes through a novel approach to better understand microbial communities by looking at protein function within them. The work was led by a team of scientists at the U.S. Department of Energy ...

【Research Study】 1. Background   Multiomics3 analysis that integrates different layers of profiles altogether is challenging, since the number of variables in profile substantially differ from each other. For instance, gene expression profile and genomic DNA methylation profile are often analyzed together, however, there are only tens of thousands of genes, whereas the number of DNA methylation sites are as many as tens of millions. The numbers differ one thousand times and the number ...

University of Virginia School of Medicine researchers have obtained new insights into how African-American and Hispanic-American people’s genes influence their ability to use Omega-3 and Omega-6 fatty acids for good health. The findings are an important step toward “precision nutrition” – where a diet tailored to exactly what our bodies need can help us live longer, healthier lives. Omega-3 and Omega-6 are “healthy fats.” We can get them from foods, but many people also take ...

An international team of scientists has identified nearly a dozen genes that contribute to calcium buildup in our coronary arteries that can lead to life-threatening coronary artery disease, a condition responsible for up to one in four deaths in the United States. Doctors may be able to target these genes with existing medications – or possibly even nutritional supplements – to slow or halt the disease’s progression. “By sharing valuable genotype and phenotype datasets collected over many years, our team was able to uncover new genes that may foreshadow clinical coronary artery disease,” said researcher Clint L. Miller, PhD, of ...

While scientific advances are made daily, foundational breakthroughs are rare and require exceptional researchers with unique points of view and questions, plus the necessary means to explore those ideas. One such researcher, Harold H. Flor, became a seminal figure in the study of plant pathology after developing the gene-for-gene concept in the mid-1900s. The gene-for-gene concept (namely, for each gene governing the host response, there is a corresponding gene in the pathogen) still stands as one of the most significant contributions to plant pathology—forever changing how scientists approach plant-microbe interactions and, more specifically, the molecular mechanisms ...

SAN ANTONIO — October 11, 2023 —Southwest Research Institute has been selected to receive a $1.5 million contract from the U.S Department of Energy to evaluate the safety and efficiency of a full-scale compressor system for hydrogen-natural gas blends containing up to 20 percent hydrogen by volume. SwRI will collaborate with the Gas Machinery Research Council (GMRC) on this project. “Hydrogen has been recognized as a viable alternative to natural gas fuel,” said SwRI Senior Research Analyst Sarah Simons. “However, a pure hydrogen stream is not compatible with existing energy transport infrastructure because hydrogen and natural gas have ...

Both elegant and fierce, killer whales are some of the oceans’ top predators, but even they can be exposed to environmental pollution. Now, in the largest study to date on North Atlantic killer whales, researchers in ACS’ Environmental Science & Technology report the levels of legacy and emerging pollutants in 162 individuals’ blubber. The animals’ diet, rather than location, greatly impacted contaminant levels and potential health risks — information that’s helpful to conservation efforts. As the largest member of the dolphin family, killer whales, also known as orcas, are ...

Because metal-organic frameworks (MOFs) — highly porous metal complexes — are so structurally and chemically diverse, they could be used for many applications, such as drug delivery and environmental clean-up. But researchers still need to get a better understanding of how they function, especially when embedded in polymers. Reporting in ACS Applied Materials & Interfaces, researchers have now developed and characterized nitric oxide (NO)-storing MOFs embedded in a thin film with novel antibacterial potential. Studying ...

The trial’s results, published in Alzheimer's and Dementia: Diagnosis, Assessment and Disease Monitoring, a journal of the Alzheimer’s Association, signal the efficacy and safety of Sailuotong (SLT), a novel herbal extract, as a potential treatment for MCI.  Trial ...

Lack of rainfall is not the only measure of drought. New UC Riverside research shows that despite a series of storms, the impact of drought can persist in streams and rivers for up to 3.5 years. There are two measures of drought in streams. One measure is the total water level, which is impacted by snowmelt and rainfall. Many researchers examine this measurement. Another measure is baseflow, which is the portion of streamflow fed by groundwater. Fewer researchers examine baseflow droughts, and there was not previously an accurate way to measure them. Because baseflow is strongly tied to groundwater, and because the ...

Research Highlights: Chronic kidney disease was strongly associated with an increased risk of sudden cardiac arrest among Hispanic/Latino adults, in a new study. Early identification and management of kidney disease may reduce risk of sudden cardiac arrest among Hispanic/Latino people, researchers suggest. Embargoed until 4 a.m. CT/5 a.m. ET Wednesday, Oct. 11, 2023 DALLAS, October 11, 2023 — Chronic kidney disease may increase risk and predict sudden cardiac arrest among Hispanic/Latino adults, according to new research published today in the Journal of the American Heart Association, an open access, peer-reviewed journal of the American ...

Hispanics and Latinos with chronic kidney disease are at significant risk for suffering from sudden cardiac arrest, according to a new study from the Smidt Heart Institute at Cedars-Sinai. During sudden cardiac arrest, the heart unexpectedly stops beating. “Because people who experience sudden cardiac arrest have a survival rate of less than 10%, prevention is extremely important,” said Kyndaron Reinier, Ph.D., associate director of Epidemiology in the Center for Cardiac Arrest Prevention at the Smidt Heart Institute and lead author of the study published in the Journal of the American Heart Association. “This study highlights the importance for Hispanic ...

Tens of thousands of endangered sharks and rays are caught by small-scale fisheries off the Republic of the Congo each year, new research shows. Scientists surveyed fish brought ashore at Songolo, which is home to more than 60% of the country's “artisanal” fishers (small boats, small engines, hand-hauled lines and nets). In three years, the team – led by the University of Exeter in partnership with the Wildlife Conservation Society (WCS) Congo Program and the Republic of the Congo’s fisheries department – recorded more than 73,000 sharks and rays landed. Most were juveniles, and 98% of individuals were of species listed as vulnerable, ...

Named after its habitat preference, Paroedura manongavato, from the Malagasy words “manonga” (to climb) and “vato” (rock), is a bouldering expert. Part of its “home range” is also very well-known to rock climbers for its massive granitic domes. “Its description represents another step into the crux (in climbing jargon, the most difficult section of a bouldering problem) of resolving the taxonomy of the recently revised P. bastardi group, where the new species belongs, and reaching a total of 25 described species in this genus, ...

Predators must eat to survive — and to survive, prey must avoid being eaten. One theory, the Wolf-Mangel model, suggests predators could use false attacks to tire prey out or force them to take bigger risks, but this has been hard to show in practice. Now, scientists observing peregrine falcons have found evidence that they deliberately exhaust their prey to improve later hunting success.  “Although predators are imagined as clever in novels and movies, like the velociraptors in Jurassic Park, empirical biologists are generally not inclined to give much credence to such ideas,” ...
