Transgender adults aged 50 or older in the United States face a significantly elevated risk of contemplating suicide due to the compounding impact of various challenges in different areas of their lives, according to a population-wide study.    More than one-fourth (25.8%) of this large pool of older transgender people acknowledged having thought about ending their lives at least once the previous year.   That is a much greater prevalence than the 4.7% figure currently estimated for the adult population-at-large and substantially ...

EMBARGOED UNTIL MONDAY, NOVEMBER 20 AT 12:01 A.M. EST COLUMBUS, Ohio – The season of comfort and joy is upon us, but a new survey finds that for many Americans, it’s the season of stress and worry. A new survey commissioned by The Ohio State University Wexner Medical Center and College of Medicine finds Americans are feeling the strain from inflation and world affairs this year, in addition to other stressors that often come with the holidays. Of the 1,007 survey respondents, 81% said that national issues and world affairs are causing them stress. In addition, 75% of respondents are ...

When we point at an object, the toddler focuses on the object, while the dog usually takes the gesture as a directional cue. In a recent study, researchers from the Department of Ethology at Eötvös Loránd University find explanations for this phenomenon. It appears that the discrepancy is not only due to how dogs see, but may, in fact, reflect how they think. For "smarter" dogs, the appearance of an object matters as much as its location, suggesting that their information processing is more similar to that of humans. Spatial bias is the phenomenon of interpreting information in relation to space, location ...

“In this ESCA study, the possibility of an immune response that selected for tumor cells lacking the DDX53 CTA is discussed.” BUFFALO, NY- November 17, 2023 – A new research paper was published in Oncoscience (Volume 10) on November 10, 2023, entitled, “An immunoinformatics assessment of the cancer testis antigen, DDX53, as a potential early esophageal cancer antigen.” T-lymphocytes have been implicated in facilitating a pro-inflammatory, pro-tumorigenic microenvironment that worsens prognosis for esophageal carcinoma (ESCA). In their new study, researchers ...

To reduce the side effects associated with chemotherapy treatments, researchers have investigated the use of delivery systems that can take more drugs directly to the tumor. Ninh (Irene) La-Beck, Pharm.D., from the Department of Immunotherapeutics and Biotechnology at the Texas Tech University Health Sciences Center (TTUHSC) Jerry H. Hodge School of Pharmacy is one of those researchers. La-Beck recently received a five-year, $2.49 million grant (“Cholesterol Metabolism in the Pharmacology of Liposomal ...

BOSTON – Glaucoma is one of the leading causes of blindness worldwide, and vision loss, due to the loss of retinal ganglion cells (RGCs), cannot currently be reversed with any treatment. Some studies have looked at replacing RGCs through cell transplants, but this process is still in the research and development stage and fraught with limitations that highlight a need for a more precise manner of effectively repopulating these cells in the retina. Now, a multidisciplinary team led by researchers at the Schepens Eye Research Institute of Mass Eye and Ear has ...

Rochester Institute of Technology’s Emiliano Brini, assistant professor in the School of Chemistry and Materials Science, has received an award from the National Institutes of Health (NIH) to support his research on building the next generation of drugs. Brini and his team of students will develop computational tools that can predict the strength of the interaction between two proteins and how drugs will modify this interaction. Physics-based methodologies will quickly and accurately provide such predictions. Designing a new ...

Small molecules called immunomodulators can help create more effective vaccines and stronger immunotherapies to treat cancer. But finding the molecules that instigate the right immune response is difficult —the number of drug-like small molecules has been estimated to be 1060, much higher than the number of stars in the visible universe. In a potential first for the field of vaccine design, machine learning guided the discovery of new immune pathway-enhancing molecules and found one particular small molecule that could outperform the best immunomodulators on the market. The ...

A new understanding of lung cancer cells’ “memories” suggests a new strategy for improving treatment, Memorial Sloan Kettering Cancer Center (MSK) researchers have found. Research from the lab of cancer biologist Tuomas Tammela, MD, PhD shows that some lung cancer cells retain a “memory” of the healthy cell where they came from — one that might be exploited to make an emerging type of lung cancer treatment called KRAS inhibition more effective. The study looked specifically at lung adenocarcinoma, a type of non-small ...

When Cyclone Idai swept through Mozambique’s Gorongosa National Park in May 2019, one of nature‘s deadliest forces encountered one of the most technologically sophisticated wildlife parks on the planet. Princeton researchers and colleagues from around the world documented the effects using trail cameras and animal-tracking devices that had been in use before the storm.  Thanks to the extensive network of cameras, GPS collars and other instruments, park staff and ...

DURHAM, N.C. – Nanoplastics interact with a particular protein that is naturally found in the brain, creating changes linked to Parkinson’s disease and some types of dementia. In a Duke-led study appearing Nov. 17 in Science Advances, the researchers report that the findings create a foundation for a new area of investigation, fueled by the timely impact of environmental factors on human biology. “Parkinson’s disease has been called the fastest growing neurological disorder in the world,” said principal investigator, Andrew West, Ph.D., professor in the Department of Pharmacology and Cancer Biology at ...

New research published today in leading international journal Science Advances paints an uncharacteristically upbeat picture for the planet. This is because more realistic ecological modelling suggests the world’s plants may be able to take up more atmospheric CO2 from human activities than previously predicted. Despite this headline finding, the environmental scientists behind the research are quick to underline that this should in no way be taken to mean the world’s governments can take their foot off the brake in their obligations to reduce carbon ...

EL PASO, Texas (Nov. 17, 2023) – Could the solution to the decades-long battle against malaria be as simple as soap? In a new study published in PLOS Neglected Tropical Diseases, scientists at The University of Texas at El Paso have made a compelling case for it. The team has found that adding small quantities of liquid soap to some classes of pesticides can boost their potency by more than ten-fold.  The discovery is promising news as malaria-carrying mosquitoes display ...

Using historical records from around Australia, an international team of researchers have put forward the most accurate prediction to date of past Antarctic ice sheet melt, providing a more realistic forecast of future sea level rise.   The Antarctic ice sheet is the largest block of ice on earth, containing over 30 million cubic kilometers of water.   Hence, its melting could have a devasting impact on future sea levels. To find out just how big that impact might be, the research team, including Dr Mark Hoggard from The Australian National University, turned to the past.   “If ...

Policies that encourage landlords to evict tenants who have involvement with the criminal justice system do not appear to reduce crime, while increasing evictions among Black residents and people with lower incomes, according to a new RAND Corporation report.   Studying “crime-free housing policies” adopted by cities in California over a decade-long period, researchers found no meaningful statistical evidence that the policies reduce crime.   The study also found that crime-free housing policies significantly increased ...

This year’s European Antibiotic Awareness Day (EAAD) focuses on the targets outlined in the 2023 Council Recommendation to step up efforts in the European Union (EU) against antimicrobial resistance in a One Health approach. [1] Those recommendations formulate the 2023 goal to reduce total antibiotic consumption (community and hospital sectors combined) by 20%, using consumption data from 2019 as baseline. Consumption of antibiotics in the community accounts for around 90% of the total use. This means, that a substantial and consistent decline in the use of antibiotics in this sector will be key on the way towards reaching ...

A team of scientists from the Institut Pasteur has used the database of the National Reference Center for Meningococci to trace the evolution of invasive meningococcal disease cases in France between 2015 and 2022, revealing an unprecedented resurgence in the disease after the easing of control measures imposed during the COVID-19 epidemic. Recently reported cases have mainly been caused by meningococcal serogroups that were less frequent before the pandemic, and there has been a particular uptick in cases among people aged 16 to 24. The results, published in the Journal of Infection and Public Health on October 12, ...

Researchers at the University of Wisconsin–Madison have identified a protein key to the development of a type of brain cell believed to play a role in disorders like Alzheimer’s and Parkinson’s diseases and used the discovery to grow the neurons from stem cells for the first time. The stem-cell-derived norepinephrine neurons of the type found in a part of the human brain called the locus coeruleus may enable research into many psychiatric and neurodegenerative diseases and provide a tool for developing ...

Migraine is more than just a headache. Often the pain is accompanied by nausea, vomiting, light sensitivity, and sound sensitivity. Chronic migraine can be disabling and may prevent many, especially women, from contributing to working life. Still, it often takes a long time for migraine patients to find a treatment that works well for them. Researchers at the Norwegian Center for Headache Research (NorHead) have used data from the Norwegian Prescription Register to look at which medicines best prevent migraine in people in Norway: “There has now been done a lot of research on this subject ...

University of B.C. researchers have uncovered startling connections between micronutrient deficiencies and the composition of gut microbiomes in early life that could help explain why resistance to antibiotics has been rising across the globe. The team investigated how deficiencies in crucial micronutrients such as vitamin A, B12, folate, iron, and zinc affected the community of bacteria, viruses, fungi and other microbes that live in the digestive system. They discovered that these deficiencies led to significant shifts in the gut ...

Researchers at the University of Pittsburgh and KU Leuven have discovered a suite of genes that influence head shape in humans. These findings, published this week in Nature Communications, help explain the diversity of human head shapes and may also offer important clues about the genetic basis of conditions that affect the skull, such as craniosynostosis. By analyzing measurements of the cranial vault — the part of the skull that forms the rounded top of the head and protects the brain — the team identified 30 regions of the genome associated with different aspects of head shape, 29 of which have not been reported previously. “Anthropologists ...

The first glucose self-monitoring system created in 1970 weighed three pounds, was initially designed only for physicians’ offices and needed a large drop of blood for a reading. Over 50 years later, researchers at Texas A&M University are working to create a fully injectable continuous glucose monitor (CGM) so small it rivals a grain of rice and can be used with an external optical reader to measure sugar levels at any given time. While CGMs have advanced over the last 25 years, current models can still be a nuisance to the user and the required upkeep may discourage use. To address this issue, two faculty members from the Department of Biomedical Engineering ...
