Hearing aids, dental crowns, and limb prosthetics are some of the medical devices that can now be digitally designed and customized for individual patients, thanks to 3-D printing. However, these devices are typically designed to replace or support bones and other rigid parts of the body, and are often printed from solid, relatively inflexible material.
More than 5 million cancer survivors in the United States experience chronic pain, almost twice the rate in the general population, according to a study published by Mount Sinai researchers in JAMA Oncology in June.
Researchers used the National Health Interview Survey, a large national representative dataset from the U.S. Centers for Disease Control and Prevention, to estimate the prevalence of chronic pain among cancer survivors. They found that about 35 percent of cancer survivors have chronic pain, representing 5.39 million patients in the United States.
Snowflakes that cover mountains or linger under tree canopies are a vital freshwater resource for over a billion people around the world. To help determine how much freshwater is stored in snow, a team of NASA-funded researchers is creating a computer-based tool that simulates the best way to detect snow and measure its water content from space.
CORVALLIS, Ore. - A tidepool crustacean's ability to survive oxygen deprivation though it lacks a key set of genes raises the possibility that animals might have more ways of dealing with hypoxic environments than had been thought.
Published in the Proceedings of the National Academy of Sciences, the findings by Oregon State University researchers are important because hypoxia - areas of low oxygen - is on the rise in waters around the globe, largely because of human-caused factors such as agricultural runoff, fossil-fuel burning and wastewater treatment effluent.
The rings of Uranus are invisible to all but the largest telescopes -- they weren't even discovered until 1977 -- but they're surprisingly bright in new heat images of the planet taken by two large telescopes in the high deserts of Chile.
On June 22, 1969, the Cuyahoga River, which flows through Cleveland, Ohio, caught fire. Although firefighters extinguished the blaze within 30 minutes, the shocking event helped galvanize the U.S. environmental movement. Fifty years later, the river is much healthier but still recuperating from a legacy of pollution, according to an article in Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society.
WASHINGTON -- Researchers have developed a new laser-based method that can detect electric charges and chemicals of interest with unprecedented sensitivity. The new approach could one day offer a way to scan large areas for radioactive material or hazardous chemicals for safety and security applications.
From effective medicines to molecular sensors to fuel cells, metal clusters are becoming fundamentally useful in the health, environment, and energy sectors. This diverse functionality of clusters arises from the variability in size and type.
Sortilin, which is a protein expressed on the surface of nerve cells, plays a crucial role in pain development in laboratory mice - and in all likelihood in humans as well. This is the main conclusion of the study 'Sortilin gates neurotensin and BDNF signalling to control peripheral neuropathic pain', which has just been published in the journal Science Advances.
Osaka, Japan - Biosensors are currently used in healthcare to monitor blood glucose; however, they also have the potential to detect bacteria. Researchers at Osaka University have invented a new biosensor using graphene--a material consisting of a one-atom-thick layer of carbon--to detect bacteria such as those that attack the stomach lining and that have been linked to stomach cancer. When the bacteria interact with the biosensor, chemical reactions are triggered which are detected by the graphene.
New York, NY--June 20, 2019--Computer scientists at Columbia Engineering have developed a new computing system that enables current, unmodified mobile apps to combine and share multiple devices, including cameras, displays, speakers, microphones, sensors, and GPS, across multiple smartphones and tablets.
Global demand for coffee and cocoa is on the rise. Yet across the equatorial belt where these two crops are produced, the future is not looking bright. Climate change in the tropics is pushing coffee and cocoa closer to the limits of physiological tolerance and constraining the places where they can grow in the future.
The first cause of the loss of functionality in transplanted pancreatic islets is the low capacity to create new vessels to allow the arrival of nutrients in the cells. This is one of the main reasons causing the failure in transplantations in the treatment of type 1 diabetes.
PITTSBURGH, June 20, 2019 - A move by the White House in 2017--decried by many health policy analysts as an attempt to undercut the Affordable Care Act (ACA)--had unanticipated consequences that improved the affordability of health insurance for Marketplace enrollees, a University of Pittsburgh Graduate School of Public Health-led analysis confirms.
Bottom Line: Inflammatory and immune-regulatory mechanisms were found to be altered in animal models and in archived prostate cancer tumor samples of responders exposed to dust from the World Trade Center terrorist attacks on Sept. 11, 2001.
