Next-gen Pacemakers May Be Powered By Unlikely Source: the Heart
October 28, 2023 9:59 am | by University at Buffalo | News | CommentsThe implantable pacemaker, a medical marvel that has extended millions of lives since its invention nearly 60 years ago, is getting a 21st century makeover. Researchers are developing technology to make these devices battery-free. The advancement is based upon a piezoelectric system that converts vibrational energy – created inside the chest by each heartbeat – into electricity to power the pacemaker.
Regeneration Faded as Most Four-legged Vertebrates Evolved
October 28, 2023 9:52 am | by Brown University | News | CommentsIn a study of fossil amphibians, paleontologists show that the capacity of modern salamanders to regenerate body parts is likely an ancient feature of four-legged vertebrates that most of them lost in evolution.
New Three-Minute Test Detects Lewy Body Disease
October 28, 2023 9:38 am | by Bevin Fletcher, Associate Editor | News | CommentsA neurologist from Florida Atlantic University has developed a new diagnostic assessment that quickly and effectively diagnoses Lewy Body disease (LBD) in about three minutes, according to a recent study published in Alzheimer’s & Dementia.
Radiotherapeutic Bandage Could Treat Skin Cancer
October 28, 2023 9:38 am | by Bevin Fletcher, Associate Editor | News | CommentsResearch behind a new radiotherapeutic bandage that could potentially treat squamous cell carcinoma (SCC) cancer was presented Wednesday, at the American Association of Pharmaceutical Scientists (AAPS) Annual Meeting and Expo in Orlando.
Direct-to-Patient Registries: A New Approach to Pharmacovigilance
October 28, 2023 9:38 am | by Nancy Dreyer, MPH, Ph.D., Global Chief of Scientific Affairs and Michelle Leavy, MPH, Manager, Health Policy, Quintiles | Articles | CommentsUnderstanding drug safety is a tricky thing. The use of direct-to-patient (or consumer) registry data is a new approach, and one that is quite different from the highly controlled world of clinical trials. Some worry about whether patients will be accurate and honest reporters. Will these patients be reliable, and will they provide clinically generalizable information?
Mental Maps: Route-Learning Changes Brain Tissue
October 28, 2023 9:36 am | by Carnegie Mellon University | News | CommentsScientists have determined that learning detailed navigation information causes the hippocampal brain changes. New research shows that brief navigation training changes a person’s brain tissue and improves how that changed tissue communicates with other brain areas involved with navigation.
Sealed Tubing Ends
October 27, 2023 10:58 am | Newage Industries, Inc. | Product Releases | CommentsAdvantaPure announces that its AdvantaFlex(R) biopharmaceutical grade TPE tubing is now available with pre-sealed ends. The ends are ideal for Single-Use biopharma and pharmaceutical applications such as sampling and storage.
Lotion Ingredient Paraben May Be More Potent Carcinogen Than Thought
October 27, 2023 10:53 am | by UC Berkeley | News | CommentsA controversial group of chemicals commonly found in lotions and other personal care products may be more dangerous at low doses than previously thought, according to a new study. The chemicals, called parabens, are preservatives widely used in everything from shampoos and cosmetics to body lotions and sunscreens.
An Intolerable Unimaginable Heat Forecast for Persian Gulf
October 27, 2023 10:42 am | by Seth Borenstein, AP Science Writer | News | CommentsIf carbon dioxide emissions continue at their current pace, by the end of century parts of the Persian Gulf will sometimes be just too hot for the human body to tolerate, a new study says. How hot? The heat index - which combines heat and humidity - may hit 165 to 170 degrees (74 to 77 Celsius) for at least six hours, according to numerous computer simulations in the new study. That's so hot that the human body can't get rid of heat.
CRISPR Brings Precise Control to Gene Expression
October 27, 2023 10:34 am | by Duke University | News | CommentsResearchers have demonstrated the exceptional specificity of a new way to switch sequences of the human genome on or off without editing the underlying genetic code. Originally discovered as an antiviral system in bacteria, CRISPR/Cas9 is one of the hottest topics in genetic research today. By engineering a version of that system, researchers can both edit DNA sequences and control which genes are used.
Mapping the 3D structure of DNA
October 27, 2023 10:16 am | by Julia Sklar, MIT News correspondent | News | CommentsPh.D. student Abe Weintraub helps identify when DNA folding is helpful, and when it might cause cancer.
Discovery Could Lead to Better Recovery After Stroke
October 27, 2023 9:55 am | by UCLA | News | CommentsResearchers have identified a molecule that, after a stroke, signals brain tissue to form new connections to compensate for the damage and initiate repairs to the brain. The finding could eventually lead to a new treatment to promote brain repair and functional recovery in people who have suffered a stroke, which is the leading cause of serious long-term disability in adults.
Seeing Sound
October 27, 2023 9:41 am | by Caltech | News | CommentsResearchers have now discovered that intrinsic neural connections--called crossmodal mappings--can be used by assistive devices to help the blind detect their environment without requiring intense concentration or hundreds of hours of training.
UN Agency Links Hot Dogs and Other Processed Meat to Cancer
October 27, 2023 8:46 am | by Angela Charlton, Associated Press | News | CommentsBacon, hot dogs and cold cuts are under fire: The World Health Organization threw its global weight behind years of doctors' warnings and declared Monday that processed meats raise the risk of colon and stomach cancer and that red meat is probably dangerous, too.
Carbon-Graphite Piston Rings
October 26, 2024 10:19 am | Product Releases | CommentsMetallized Carbon Corporation, a manufacturer of oil-free, self-lubricating, carbon-graphite materials for severe service lubrication applications, announces the availability of carbon-graphite for use in piston rings needed to seal high pressure gas in applications requiring compressed gases that do not contain oil or grease. The piston rings are used in conjunction with carbon-graphite guide rings or carrier rings, which hold the piston centered on...
