Blood test identifies acute myeloid leukemia patients at greater risk for relapse after bone marrow transplant  A small portion of adults in remission from a deadly blood cancer had persisting mutations that were detected, which predicted their risk of death from having the cancer return    Researchers at the National Institutes of Health show the benefits of screening adult patients in remission from acute myeloid leukemia (AML) for residual disease before receiving a bone marrow transplant. The findings, published in JAMA, support ongoing research aimed ...

The whistleblowers who once trusted journalism are losing faith in the institution. A new study from the University of Georgia found that many whistleblowers who reached out to journalists in the past no longer believe media has the same ability to motivate change, and they feel let down by a system they once trusted. “If you don’t believe that an outlet or journalist can carry you across the finish line—meaning can affect change, attract enough attention and attract the attention of the right people—then you’re losing faith,” said Karin Assmann, study lead and assistant professor in UGA’s Grady College of Journalism ...

SAN ANTONIO — March 7, 2023 —The Supercritical Transformational Electric Power (STEP) Demo pilot plant, a $155 million, 10-megawatt supercritical carbon dioxide (sCO2) test facility at Southwest Research Institute (SwRI) in San Antonio, developed in partnership with GTI Energy and GE Research and sponsored by the U.S. Department of Energy, has successfully achieved its first operation with CO2 at supercritical fluid conditions in its compressor section. This accomplishment represents significant progress toward ...

Pediatric acute myeloid leukemia or pAML is a childhood blood cancer, one that has proved confounding to clinicians and researchers, with a high relapse rate and relatively few identified genetic mutations (compared to the adult version) that might explain its cause.   In a new study, published in the March 7, 2023 issue of Cell Reports, an international team led by scientists and physicians at University of California San Diego School of Medicine deployed an array of analytical and gene-splicing tools to parse more deeply the mysteries of mutation in pAML.  “Compared to adult AML, pediatric AML is associated with relatively ...

How well you synchronize to a simple beat predicts how well you synchronize with another mind, according to a new Dartmouth study published in Scientific Reports. Previous work has demonstrated that the pupil dilation patterns of speakers and listeners synchronize spontaneously, illustrating shared attention. The team set out to understand how the tendency to synchronize in this way may vary at the individual level and generalize across contexts, as it has been widely debated whether one form of synchrony bears any relationship to another. “We were ...

SAN FRANCISCO, CA—March 7, 2023—Compared to those of us who live at sea level, the 2 million people worldwide who live above 4,500 meters (or 14,764 feet) of elevation—about the height of Mount Rainier, Mount Whitney, and many Colorado and Alaska peaks—have lower rates of metabolic diseases such as diabetes, coronary artery disease, hypercholesterolemia, and obesity. Now, researchers at Gladstone Institutes have shed light on this phenomenon. They showed how chronically low oxygen levels, such as those experienced at high elevation, rewire how mice burn sugars ...

BOSTON – New research led by investigators at Massachusetts General Hospital (MGH), a founding member of Mass General Brigham (MGB), indicates that socioeconomic and genetic factors likely interact in an additive way to affect people’s risks of developing obesity and type 2 diabetes. The findings, which are published in Diabetes Care, suggest that interventions to improve socioeconomic deprivation may decrease metabolic diseases at the individual and community levels, especially among people with concomitant high genetic risk. Genetic and socioeconomic factors—one intrinsic and unmodifiable and ...

A new RAND Corporation report finds that the basic infrastructure to support elementary (grades K-5) social studies instruction – academic standards, accountability requirements, assessment programs – is inadequate in many states. Even where state-level infrastructure to guide teachers’ instruction is in place, its comprehensiveness and quality vary greatly. Support and guidance at the district and school level to underpin social studies instruction are also lacking compared to other core academic ...

Scientists at Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a conductive polymer coating – called HOS-PFM – that could enable longer lasting, more powerful lithium-ion batteries for electric vehicles.  “The advance opens up a new approach to developing EV batteries that are more affordable and easy to manufacture,“ said Gao Liu, a senior scientist in Berkeley Lab’s Energy Technologies Area. The HOS-PFM coating conducts both electrons and ions at the same time. This ensures battery stability and high charge/discharge rates while enhancing battery life. The coating ...

BIRMINGHAM, Ala. – A United States Food and Drug Administration mandate to limit the dosage of acetaminophen in pills that combine acetaminophen and opioid medications is significantly associated with subsequent reductions in serious liver injury, researchers report in the medical journal JAMA. The federal mandate was announced in 2011 and implemented in 2014. “The FDA mandate that limits acetaminophen dosage to 325 milligrams per tablet in combination acetaminophen-opioid medications was associated with a significant and persistent decline in the yearly rate of hospitalizations and proportion per year of acute liver failure ...

WASHINGTON, March 7, 2023 – Proxy data – indirect records of the Earth’s climate found in unlikely places like coral, pollen, trees, and sediments – show interesting oscillations approximately every 100,000 years starting about 1 million years ago. Strong changes in global ice volume, sea level, carbon dioxide concentration, and surface temperature indicate cycles of a long, slow transition to a glacial period and an abrupt switch to a warm and short interglacial period. Milutin Milankovitch hypothesized that the timing of these cycles was controlled by the orbital parameters of the Earth, including the shape of its path around ...

A hormone called fibroblast growth factor 21 (FGF21) protects mice against ethanol-induced loss of balance and righting reflex, according to a study publishing on March 7 in the journal Cell Metabolism. “We’ve discovered that the liver is not only involved in metabolizing alcohol but that it also sends a hormonal signal to the brain to protect against the harmful effects of intoxication, including both loss of consciousness and coordination,” says co-senior study author Steven Kliewer of the University of Texas Southwestern Medical Center. “We’ve further shown that by increasing FGF21 concentrations even higher by injection, we can dramatically ...

At a glance: New research suggests female mice show more stable exploratory behavior than male mice, despite hormone cycles The results challenge a long-held assumption that hormones have a broad effect on behavior in female mice, making them less suitable for research The findings make a strong scientific case for increasing the inclusion of female mice in neuroscience and other experiments Mice have long been a central part of neuroscience research, providing a flexible model that scientists ...

About The Study: The findings of this study suggest that despite initial telemedicine gains at rural Veterans Affairs (VA) health care sites, the pandemic was associated with an increase in the rural-urban telemedicine divide across the VA health care system. To ensure equitable access to care, the VA health care system’s coordinated telemedicine response may benefit from addressing rural disparities in structural capacity (e.g., internet bandwidth) and from tailoring technology to encourage adoption among rural users.  Authors: Lucinda B. Leung, M.D., Ph.D., M.P.H., of the Veterans Affairs Greater Los Angeles Healthcare System in Los Angeles, is the corresponding ...

A United States Food and Drug Administration mandate to limit the dosage of acetaminophen in pills that combine acetaminophen and opioid medications is significantly associated with subsequent reductions in serious liver injury, according to a study led by investigators at the University of Alabama and Weill Cornell Medicine. The federal mandate was announced in 2011 and implemented in 2014. The results were reported March 7 in the medical journal JAMA. “After researchers found that more than 40 percent of acetaminophen-induced acute liver failure cases involved combination acetaminophen and opioid medications, and an FDA advisory ...

The selective breeding of grain crops is one of the main reasons why domesticated plants produce such excellent yields. Selecting the best candidates for breeding is, however, a remarkably complex task. On one hand, it requires a skilled breeder with trained eyes to assess plant resistance to disease and pests, crop growth, and other factors. On the other hand, it also requires precise tool-assisted measurements such as grain size, mass, and quality. Although all these standard measures are useful, none of them takes into account the number ...

Safe live microorganisms are found in a variety of foods we eat every day, from yogurt and other fermented foods, to raw fruits and vegetables. Despite the widespread idea that these mixtures of live microbes contribute to health, convincing evidence linking live dietary microbes to health benefits has been lacking. A new study provides some of the first real-world evidence that higher consumption of live microbes may promote health. A group of scientists led by the International Scientific Association for Probiotics and Prebiotics (ISAPP) classified over 9,000 individual ...
