New research from Cedars-Sinai Cancer investigators could warrant reconsideration of current screening guidelines to include a poorly recognized cause of Lynch syndrome, the most common cause of hereditary colorectal and endometrial cancers. Their study, published today in the JNCCN—Journal of the National Comprehensive Cancer Network, concluded that the guidelines leave a significant number of patients undiagnosed. “When patients with Lynch syndrome—whose first cancers generally appear at an early age—aren’t diagnosed promptly, they don’t get appropriate follow-up or surveillance,” said Megan Hitchins, ...

MINNEAPOLIS/ST. PAUL (07/11/2023) — Researchers at the University of Minnesota Medical School recently received a four-year award from the Defense Advanced Research Projects Agency’s (DARPA’s) Neural Evidence Aggregation Tool program. The goal of their project— titled Fast, Reliable Electrical Unconscious Detection (FREUD)—is to develop tools to better detect early symptoms of depression, psychosis and suicidality, with the intent that treatment can be started as early in a condition’s trajectory as possible. “It’s exactly those early moments when getting someone therapy or mental health services could save their life or ...

DENVER — Recently published research suggests that despite showing clear symptoms of chronic obstructive pulmonary disease (COPD), many African Americans are not officially diagnosed with the disease due to flaws in diagnosis methods.  The Research was led by National Jewish Health and recently published in the Journal of General Internal Medicine from the COPDGene study.  Fixed-ratio spirometry, a standard method of measuring respiratory capacity, has long been used as a method of detecting COPD. ...

Genome-wide screen in the nematode Caenorhabditis elegans reveals potential targets to delay motor aging, including the phosphatidylinositol 3-kinase VPS-34; genetic and pharmacological partial inhibition of VPS-34 improves neurotransmission and muscle integrity through increased PI(3)P-PI-PI(4)P conversion, ameliorating motor aging in both worms and mice. ##### In your coverage, please use this URL to provide access to the freely available paper in PLOS Biology:   http://journals.plos.org/plosbiology/article?id=10.1371/journal.pbio.3002165 Article ...

GRAND FORKS, N.D., July 11, 2023   ̶  Scientists at the USDA Agricultural Research Service’s (ARS) Grand Forks Human Nutrition Research Center led a study that demonstrates it is possible to build a healthy diet with 91 percent of the calories coming from ultra-processed foods (as classified using the NOVA scale) while still following the recommendations from the 2020-2025 Dietary Guidelines for Americans (DGA). The study highlights the versatility of using DGA recommendations in constructing healthy menus. “The study is a proof-of-concept that shows a more balanced view of healthy ...

The body’s blood glucose level needs to be maintained in a relatively narrow range. It cannot be too high, as it can lead to diabetes, and it cannot be too low because it can cause fainting or even death. “There are many glucose-sensing neurons in the brain that are thought to actively participate in detecting small changes of glucose levels in the body and then trigger responses accordingly to return the level to a healthy range,” said Dr. Yong Xu, professor of pediatrics – nutrition, ...

In 2020, Tufts Wildlife Clinic Director Maureen Murray, V03, published a study that showed 100% of red-tailed hawks tested at the clinic were positive for exposure to anticoagulant rodenticides (ARs). Such exposure occurs when these chemicals are used to kill mice or rats, which eat the poison, and the birds eat the poisoned prey. Now, Murray is expanding that research with a new study published recently in the journal Environmental Pollution, which found that another type of rodenticide—a neurotoxicant called bromethalin—also ...

ANN ARBOR, Michigan — A new analysis finds that up to millions of dollars could be saved annually on cancer immunotherapy treatments across the Veterans Health Administration by reconsidering how those drugs are delivered.   It’s a concept that could be applied to all cancer centers nationwide. Immune checkpoint inhibitors were initially tested and approved at weight-based dosages but then moved to one-size-fits-all flat doses, in part to reduce drug waste. But researchers from the University of Michigan Rogel Cancer Center found that if vials intended for a single ...

EDMONTON — Researchers have found a link between chemotherapy-induced changes to gut bacteria and the unhealthy weight gain seen in breast cancer patients, pointing the way to potentially help survivors avoid obesity-related illness later in their lives.  In newly published research, a team at the University of Alberta found that the patients treated with chemotherapy lost muscle mass and gained abdominal fat, which has been linked to heart disease, diabetes and even cancer recurrence. The chemo patients also exhibited signs of inflammation and significant changes to the number and variety of bacteria in their guts. “Changes in the bacterial populations ...

ITHACA, N.Y. -- Filmmakers may soon be able to stabilize shaky video, change viewpoints and create freeze-frame, zoom and slow-motion effects – without shooting any new footage – thanks to an algorithm developed by researchers at Cornell University and Google Research. The software, called DynIBar, synthesizes new views using pixel information from the original video, and even works with moving objects and unstable camerawork. The work is a major advance over previous efforts, which ...

CLEVELAND–Case Western Reserve University chemical engineer Rohan Akolkar is leading a research team working to develop a new zero-carbon, electrochemical process to produce iron metal from ore.   If successful, the project could be a first step toward eliminating harmful greenhouse gas emissions by eventually replacing century-old, blast-furnace ironmaking with a new electrolytic-iron production process.   Reducing iron ore to metal is carbon- and energy-intensive, leading to significant carbon-dioxide emissions that drive global warming.   “We don’t use carbon at all in our process, so ...

CLEVELAND—U.S. military veterans who lived in what were once known as “redlined” areas had a higher risk for heart attacks and other cardiovascular issues, according to a new study by researchers at Case Western Reserve University, University Hospitals and the Cleveland VA Medical Center. In the 1930s, the federal government-sponsored Homeowners’ Loan Corp. (HOLC) established maps of U.S. neighborhoods that identified levels of mortgage risk. This practice led to disinvestments and segregation in “redlined” neighborhoods. Judicial rulings--and, later, federal legislation--prohibited such government practices, but research has shown their ...

One of the most powerful psychedelics known, N,N-dimethyltryptamine (DMT) has been described as causing imaginative visuals akin to the dream state. It is typically consumed on its own or in ayahuasca, a ceremonial brew that has been used for spiritual and visionary purposes by indigenous cultures for centuries. Some have expressed that DMT helped address psychological ailments such as depression and addiction, promoting emotional well-being. However, the way that DMT impacts the brain, body and health is largely unknown. A ...

Not all carbon emissions are made for the same reason—they range from more essential purposes like heating a home to nonessential “luxury” activities like leisure travel. However, proposals for the implementations of carbon taxes tend to apply to all emissions at an equal rate. This can give rise to and exacerbate inequalities. A new analysis published on July 11 in the journal One Earth suggests taxing luxury carbon emissions at a higher rate instead; if all 88 countries analyzed in this study adopted the luxury-focused policy, this would achieve 75% of the emissions reduction needed to reach the Paris Agreement’s goal of limiting climate change ...

When an electric vehicle is parked outside, its temperature can swing wildly from day to night and season to season, which can lead to deterioration of the battery. To dampen these fluctuations and extend the battery’s lifespan, researchers have designed an all-season thermal cloak that can cool an electric vehicle by 8°C on a hot day and warm it by 6.8°C at night. The cloak, made predominantly of silica and aluminum, can do so passively without outside energy input and operates without any modification between hot or cold weather. This prototype is described July 11 in the newly launched Device, an application-oriented sister journal ...

WASHINGTON, July 11, 2023 – Compared to artificial tears, or eye drops, human tears are significantly more complex liquids, with a wide range of components including lipids, carbohydrates, proteins, water, and salt. It is this complex mixture that gives tears the perfect thickness and ability to moisturize the eye, a design that is hard to replicate with fewer ingredients. In Physics of Fluids, from AIP Publishing, Vega et al. researched human tears at the micron level to reveal new ways of customizing artificial tears to address individual symptoms of dry eye disease. The detailed insights they gained about the composition and behavior ...

Unborn babies use ‘greedy’ gene from dads to ‘remote-control’ mums into feeding them extra food Fetuses use a copy of a gene inherited from their dad to force their mum to release as much nutrients as possible during pregnancy, Cambridge scientists have discovered. The unborn baby ‘remote controls’ its mother’s metabolism so the two are in a nutritional tug of war. The mother’s body wants the baby to survive but needs to keep enough glucose and fats circulating in her system for her own health, to be able to deliver ...
