A team from Ames National Laboratory conducted an in-depth investigation of the magnetism of TbMn6Sn6, a Kagome layered topological magnet. They were surprised to find that the magnetic spin reorientation in TbMn6Sn6 occurs by generating increasing numbers of magnetically isotropic ions as the temperature increases. Rob McQueeney, a scientist at Ames Lab and project lead, explained that TbMn6Sn6has two different magnetic ions in the material, terbium and manganese. The direction of the manganese moments controls the topological state, “But ...

Hypertensive disorders of pregnancy such as preeclampsia and gestational hypertension occur in up to 10% of pregnancies and are associated with a three-fold increased risk of chronic hypertension and up to two-fold increased risk of cardiovascular disease when compared with healthy pregnancies. While the year after pregnancy is a critical time to address hypertension risk with lifestyle changes (healthy diet and exercise), the effects of lifestyle interventions on postpartum blood pressures are not well documented.   A new Boston University Chobanian & Avedisian School of Medicine study has found that there are few relevant studies on the ...

We use plastics in almost every aspect of our lives. These materials are cheap to make and incredibly stable. The problem comes when we're done using something plastic — it can persist in the environment for years. Over time, plastic will break down into smaller fragments, called microplastics, that can pose significant environmental and health concerns. The best-case solution would be to use bio-based plastics that biodegrade instead, but many of those bioplastics are not designed to degrade in backyard composting conditions. They must be processed in commercial composting facilities, which are not accessible in all regions of the ...

URBANA, Ill. — For those whose primary experience with corn is the butter-drenched cob variety, it might come as a surprise that other forms of sweet corn are in trouble. A new University of Illinois Urbana-Champaign analysis shows sweet corn production for frozen and canned products has been steadily shrinking in the U.S. over the past 27 years, particularly in rainfed portions of the Midwest.  “The processing sweet corn industry [corn grown for canned and frozen products] was thriving in the U.S. throughout the 20th century. This type of production, ...

Antiracist Structural Intervention at the Emory University Institutional Review Board Francois Rollin, Vanessa Van Doren, Jessica Alvarez, Rebecca Rousselle, Jada Bussey-Jones   Although racial and ethnic categories are social constructs without inherent biologic or genetic meaning, race and ethnicity impact health outcomes through racism. The use of racial categories in biomedical research often misattributes the cause of health inequities to genetic and inherent biological differences rather than to racism. Improving research ...

Philadelphia, July 10, 2023 – A long-standing and contentiously debated question is the extent to which US federal food assistance programs contribute to or deter healthy beverage intake. Findings of a new study in the Journal of Nutrition Education and Behavior, published by Elsevier, show that while beverage intake patterns rarely differed between mothers and young children who participated only in the Supplementation Nutrition Program for Women, Infants, and Children (WIC), only the Supplemental ...

JULY 10, 2023, NEW YORK – A Ludwig Cancer Research study has discovered that the presence of relatively high numbers of immune cells known as monocytes in tumors is linked to better outcomes in esophageal cancer patients treated with a combination of chemotherapy and immunotherapy, or immunochemotherapy. Esophageal cancer is the sixth leading cause of cancer mortality worldwide, and the incidence of esophageal adenocarcinoma has been climbing at a relatively swift clip over the past 40 years. Survival times for inoperable or metastatic forms of the cancer range from 6 to 12 months. Led by Ludwig Oxford Director Xin Lu and ...

ITHACA, N.Y. -- Humans make lots of irrational decisions in predictable ways, but what if we’re all just doing our best within the limits of our abilities? Researchers were able to simulate human behaviors using a probabilistic finite automaton, a well-known model of limited computational power. They programmed the automatons to compete against each other in a wildlife poaching game, as either a rhino poacher or a ranger trying to stop the poaching. When the automatons could remember everything, they settled into an optimal game strategy. But when researchers limited their memories, they took some decision-making shortcuts – the same ...

Indonesia, home to the largest tropical rainforest in Southeast Asia and over 17,500 islands, is a country packed with biodiversity and endangered species. However, scientists studying the region’s species and ecosystems are getting banned from Indonesia, and conservation plans are being blocked. In a letter publishing in the journal Current Biology on July 10, a team of conservation researchers with long-term experience in Indonesia discuss scientific suppression and other research challenges they have witnessed while working in the region. They offer suggestions for how to promote nature conservation, protect data ...

Nitric oxide (NO) is a fascinating and versatile molecule, important for all living things as well as the environment. It is highly reactive and toxic, organisms use it as a signaling molecule, it depletes the ozone layer in our planet’s atmosphere, and it is the precursor of the greenhouse gas nitrous oxide (N2O). Moreover, NO might have played a fundamental role in the emergence and evolution of life on Earth, as it was available as a high-energy oxidant long before there was oxygen. Thus, despite its toxicity, it makes perfect sense that microbes use NO to grow. However, research on the topic is scarce and, to date, microbes growing on it have not been cultivated. ...

Observations of a wild colony of macaques over three years show same-sex sexual behaviour among males is widespread and may be beneficial. The results, published today in Nature Ecology and Evolution, suggest same-sex sexual behaviour (SSB) has evolved and may be a common feature of primate reproduction. Conducted by researchers at Imperial College London, the observations and genetic data form the first long-term study of SSB in males within one species. Their study challenges the beliefs of some that SSB is a rare behaviour in non-human ...

In a peer-reviewed opinion paper publishing July 10 in the journal Patterns, researchers show that computer programs commonly used to determine if a text was written by artificial intelligence tend to falsely label articles written by non-native language speakers as AI-generated. The researchers caution against the use of such AI text detectors for their unreliability, which could have negative impacts on individuals including students and those applying for jobs. “Our current recommendation ...

The summer of 2022 was the hottest summer ever recorded in Europe and was characterised by an intense series of record-breaking heat waves, droughts and forest fires. While Eurostat, the European statistical office, already reported unusually high excess mortality for those dates, until now the fraction of mortality attributable to heat had not been quantified. This is precisely what has been done in a study led by the Barcelona Institute for Global Health (ISGlobal), a centre supported by the "la Caixa" ...

Brain tissue is one of the most intricate specimens that scientists have arguably ever dealt with. Packed with currently immeasurable amount of information, the human brain is the most sophisticated computational device with its network of around 86 billion neurons. Understanding such complexity is a difficult task, and hence making progress requires technologies to unravel the tiny, complex interactions taking place in the brain at microscopic scales. Imaging is therefore an enabling tool in neuroscience. The new imaging and virtual reconstruction technology developed by Johann Danzl’s group at ISTA is a ...

About The Study: Based on U.S. nationally representative data, the estimated learning disability prevalence was 8.83% among children and adolescents ages 6 to 17 from 1997 to 2021, which was slightly higher than that from a previous National Health Interview Survey study from 2009 to 2017 (7.74%). These data indicate that learning disability is a common chronic condition among U.S. children, affecting about 9 in 100 overall. In this population-based study, no significant annual change was found.  Authors: Wenhan ...
