WEST LAFAYETTE, Ind. -- The chemical element that makes up most of today's batteries, lithium, may soon be challenged by its polar opposite on the Periodic Table: fluoride. Yes, the same stuff in toothpaste.
The two elements would be in competition for helping electronics last longer on a charge, such as electric cars that need to travel more miles than is possible with lithium-ion batteries on the market.
In the diagnosis of Alzheimer's disease and the search for effective treatments, tau tangles in the brain have joined amyloid build-up as markers of the disease and potential therapy targets. In the December issue of The Journal of Nuclear Medicine, the featured article of the month reports on the identification of a promising second-generation positron emission tomography (PET) tracer for imaging and measuring tau pathology.
Everyone makes little everyday mistakes out of habit--a waiter says, "Enjoy your meal," and you respond with, "You, too!" before realizing that the person is not, in fact, going to be enjoying your meal. Luckily, there are parts of our brains that monitor our behavior, catching errors and correcting them quickly.
The spread of invasive cancer cells from a tumor's original site to distant parts of the body is known as metastasis. It is the leading cause of death in people with cancer. In a paper published online in iScience, University of California San Diego School of Medicine researchers reported engineering sensors that can detect and measure the metastatic potential of single cancer cells.
For the physics community, the discovery of new particles like the Higgs Boson has paved the way for a host of exciting potential experiments. Yet, when it comes to such an elusive particle as the Higgs Boson, it's not easy to unlock the secrets of the mechanism that led to its creation. The experiments designed to detect the Higgs Boson involve colliding particles with sufficiently high energy head-on after accelerating them in the Large Hadron Collider (LHC) at CERN in Geneva, Switzerland.
Researchers studying Alzheimer's disease have created an approach to classify patients with Alzheimer's disease, a finding that may open the door for personalized treatments.
"Alzheimer's, like breast cancer, is not one disease," said lead author Shubhabrata Mukherjee, research assistant professor in general internal medicine at the University of Washington School of Medicine. "I think a good drug might fail in a clinical trial because not all the subjects have the same kind of Alzheimer's.
The higher rates of firearms suicide among white Americans after the age of 20 hasn't offset this yawning and widening racial gap in death rates linked to gun violence, the figures show.
Firearm deaths have become a major public health problem in the USA: US men can expect to live shorter lives than their peers in many other countries. And while overall US life expectancy increased from 76.8 in 2000 to 78.7 in 2014, it fell for the first time in 50 years in 2015, a trend that continued in 2016.
The amount of time you sleep, including daytime naps, is linked to your risk of developing cardiovascular disease and death, according to a study of over 116,000 people in seven regions of the world, published in the European Heart Journal [1] today (Wednesday).
An international group of scientists led by researchers from the University of Bristol have advanced our understanding of how ancient animals saw the world by combining the study of fossils and genetics.
Ancestors of insects and crustaceans that lived more than 500 million years ago in the Cambrian period were some of the earliest active predators, but not much is known about how their eyes were adapted for hunting.
COLUMBUS, Ohio - There are many organizations monitoring endangered species such as elephants and tigers, but what about the millions of other species on the planet -- ones that most people have never heard of or don't think about? How do scientists assess the threat level of, say, the plicate rocksnail, Caribbean spiny lobster or Torrey pine tree?
Sleep hygiene, which includes practices like providing a cool and quiet sleeping environment or reading before bed time to help kids unwind, is increasingly popular among parents looking to ensure their children get a good night's rest. But are these practices all they're cracked up to be? University of British Columbia sleep expert and nursing professor Wendy Hall recently led a review of the latest studies to find out.
MIAMI--A new study helping to improve how sustainability is measured for popular reef fish could help better assess the eco-friendly seafood options at the dinner table.
A team of researchers at the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science and NOAA Fisheries tested their newly developed fishery risk assessment method on groupers and snappers in the Florida Keys to determine if these tropical reef fish are being managed sustainability.
NEW YORK, December 1, 2018 - Researchers conducting a 5-year-long study examining snow cover in a northern hardwood forest region found that projected changes in climate could lead to a 95 percent reduction of deep-insulating snowpack in forest areas across the northeastern United States by the end of the 21st century. The loss of snowpack would likely result in a steep reduction of forests' ability to store climate-changing carbon dioxide and filter pollutants from the air and water.
Today's political climate in the U.S. is often peppered with animosity from the U.S. president towards other countries but how has the U.S. image fared? A Dartmouth study finds that the U.S. image abroad appears to be influenced more by policy content than by the person delivering the message, even if it is the U.S. president. The results are published in Political Behavior.
