Physicists at the Weizmann Institute of Science in Israel have imaged electrons flowing viscously through a nanodevice, just like water flowing through a pipe. Long predicted but only now visualized for the first time, this curious new behavior for electrons has important implications for future electronic devices.
A new study led by the Sainte-Justine University Hospital Centre and the University of Montreal, along with the Washington University School of Medicine in St. Louis, has found that transfusions using fresh red blood cells--cells that have spent seven days or less in storage--are no more beneficial than older red blood cells in reducing the risk of organ failure or death in critically ill children. The results are published online today in the Journal of the American Medical Association.
Over $650 million annually is raised for medical needs on the crowdfunding platform GoFundMe, with 1,059 campaigns for unproven and potentially dangerous interventions identified in one search. Crowdfunding campaigns can "mislead donors, spread misinformation and may even harm those receiving the money," write authors Jeremy Snyder and I.
Most synthetic materials, including those in battery electrodes, polymer membranes, and catalysts, degrade over time because they don't have internal repair mechanisms. If you could distribute autonomous microrobots within these materials, then you could use the microrobots to continuously make repairs from the inside. A new study from the lab of Kyle Bishop, associate professor of chemical engineering, proposes a strategy for microscale robots that can sense symptoms of a material defect and navigate autonomously to the defect site, where corrective actions could be performed.
Despite the numerous benefits associated with patients accessing their medical records, a study by a new Portland State University professor found only 10% of patients utilize the resource.
New research shows that for every £1 invested in pollinator monitoring schemes, at least £1.50 can be saved, from otherwise costly independent research projects.
A research team from the University of Reading and the UK Centre for Ecology & Hydrology is studying how to improve pollinator monitoring in the UK in a cost-effective manner. The preliminary results are presented today at the British Ecological Society's annual meeting in Belfast.
Children in low resourced countries are 100-200 times more likely to die after surgery than children in wealthy countries, according to a first-of-its-kind study published in Anesthesiology.
Two billion of the world's children lack access to safe surgery and anesthesia, and the need for pediatric surgery in low- and middle-income countries is growing, according to lead author Mark Newton, MD, a pediatric anesthesiologist at Monroe Carell Jr. Children's Hospital at Vanderbilt and Director of Anesthesia Global Health and Development in the Department of Anesthesiology.
A treatment called extracorporeal shockwave therapy (ESWT) is used in patients both human and equine to speed healing of injured tendons and ligaments. Using high-pressure sonic waves, ESWT is thought to increase blood flow to the treated area and has been shown to reduce pain over the short term.
In racehorses, however, masking pain can come with a cost: Overworked minor injuries could lead to major ones or even pose a life-threatening risk to both horse and rider.
By their nature, hospitals are fast-paced environments that can induce some stress in the people who work there. Often, the roles taken on by people saving others' lives are somewhat thankless. For this reason, Penn Medicine's Center for Digital Health created "High Five," a web-based recognition system that enables staff members to easily use social media-style memes and humor to compliment each other on anything from the routine to the extraordinary.
University of Otago researchers have discovered how viruses that specifically kill bacteria can outwit bacteria by hiding from their defences, findings which are important for the development of new antimicrobials based on viruses and provide a significant advance in biological knowledge.
More than 1 million people have died in the 1800 magnitude 5+ earthquakes recorded worldwide since 2000.
Bridges are the most vulnerable parts of a transport network when earthquakes occur, obstructing emergency response, search and rescue missions and aid delivery, increasing potential fatalities.
Imperial College London bioengineers have found a way to create stretchy and squeezy soft sensing devices by bonding rubber to electrical components.
Stretchy and squeezy soft sensors that can fit around body parts or squeezed in hands could be used for applications including sports and rehabilitation after injury or stroke. For example, soft electrical force sensors in the form for a squeeze ball could monitor the rehabilitation of patients with hand injuries or neurological disorders.
For parents worried that their teenager's narcissism is out of control, there's hope. New research from Michigan State University conducted the longest study on narcissism to date, revealing how it changes over time.
"There's a narrative in our culture that generations are getting more and more narcissistic, but no one has ever looked at it throughout generations or how it varies with age at the same time," said William Chopik, associate professor of psychology at MSU and lead author.
Living beings contain their own assembly and operating instructions in the form of DNA. That's not the case with inanimate objects: anyone wishing to 3D print an object also requires a set of instructions. If they then choose to print that same object again years later, they need access to the original digital information. The object itself does not store the printing instructions.
SEATTLE -- Dec. 9, 2019 -- What if a metal that's already used to repair broken bones, straighten teeth and keep arteries from clogging could also be used to stop your cancer from spreading?
New findings published Dec. 9 in Nature Biomedical Engineering from scientists at Fred Hutchinson Cancer Research Center show for the first time that a piece of small, thin metal mesh loaded with cancer-fighting immune cells shrinks tumors in preclinical models of ovarian cancer.
