Potential targets to delay motor aging revealed by C. elegans genome-wide screen

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 ...

July 11, 2023 – A leading forensic nurse researcher has developed new approaches to detecting bruises in patients with darker skin tones – thus helping to overcome barriers to diagnosing injuries in patients of color, according to a special article on nurse innovators in the July issue  of the American Journal of Nursing (AJN). The journal is published in the Lippincott portfolio by Wolters Kluwer. The article highlights the work of Katherine Scafide, PhD, RN, of George Mason University, Fairfax, Va., whose "nonconventional program ...

WASHINGTON — Climate change is not only making Georgia hotter but also increasing the likelihood of snake bite, according to a new study. Every degree Celsius of daily temperature increase corresponds with about ...

1675 theory states a hanging chain mirrors shape of an upstanding rigid arch Research from Aston University shows that this common-held belief is incorrect Explained using transition from Newtonian to Lagrangian mechanics and mathematical rigour.     Monday 10 July 2023 | Birmingham, UK   An Aston University researcher has turned one of the basic rules of construction on its head.   For centuries a hanging chain has been used as an example to explain how masonry arches stand.   Structural engineers are familiar ...

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 ...
