Researchers at Stevens Institute of Technology have developed an AI-powered, smart insole that instantly turns any shoe into a portable gait-analysis laboratory.
OAK BROOK, Ill. - Medical radiation exposure to patients in the U.S. fell by 20% between 2006 and 2016, reversing a quarter century-long trend of increasing exposure, according to a study appearing in the journal Radiology.
The use of medical imaging has grown rapidly in recent decades, raising concerns about the exposure of patients to ionizing radiation. A landmark report published in 2008 found that per capita radiation exposure in the U.S. increased six-fold between 1980 and 2006.
Permafrost soils in the Arctic are thawing. As they do, large additional quantities of greenhouse gases could be released, accelerating climate change. In Russia, experiments are now being conducted in which herds of horses, bison and reindeer are being used to combat this effect. A study from Universität Hamburg, just released in the Nature journal Scientific Reports, now shows for the first time that this method could indeed significantly slow the loss of permafrost soils.
Cancer cells grow and divide in an uncontrolled manner. A new study from Uppsala University now shows how alterations in a cell's degradation hubs, called lysosomes, can cause abnormal cell growth. The results are published today in the scientific journal Nature Communications.
Senior citizens who are not vitamin D deficient have a better chance of walking after hip fracture surgery, according to a Rutgers-led study.
Stimulating immune cells with two cancer immunotherapies together can shrink the size of the viral "reservoir" in SIV (simian immunodeficiency virus)-infected nonhuman primates treated with antiviral drugs, Emory University researchers and their colleagues have concluded. The reservoir includes immune cells that harbor virus despite potent antiviral drug treatment.
A major advance in revealing the unknown plant diversity on planet Earth is made with a new monograph, published in the open-access, peer-reviewed journal PhytoKeys.
A major challenge in neuroscience lies in understanding how molecular and circuit differences in the brain synergistically contribute to sex differences in behavioral phenotypes. Sex differences in the brain may arise from the identity, distribution and relative abundance of cell types.
Mysterious bone circles made from the remains of dozens of mammoths have revealed clues about how ancient communities survived Europe's ice age.
About 70 of these structures are known to exist in Ukraine and the west Russian Plain.
New analysis shows the bones at one site are more than 20,000 years old, making it the oldest such circular structure built by humans discovered in the region. The bones were likely sourced from animal graveyards, and the circle was then hidden by sediment and is now a foot below current surface level.
A noblewoman from Imperial China enjoyed playing polo on donkeys so much she had her steeds buried with her so she could keep doing it in the afterlife, archaeologists found. This discovery by a team that includes Fiona Marshall, the James W. and Jean L. Davis Professor in Arts & Sciences at Washington University in St. Louis, is published March 17 in the journal Antiquity.
Rutgers researchers have discovered the origins of the protein structures responsible for metabolism: simple molecules that powered early life on Earth and serve as chemical signals that NASA could use to search for life on other planets.
Their study, which predicts what the earliest proteins looked like 3.5 billion to 2.5 billion years ago, is published in the journal Proceedings of the National Academy of Sciences.
A drug candidate has been found in preclinical trials to stop tumor growth entirely, deliver more cancer-busting power than many commonly used chemotherapy drugs and do so with fewer toxic side effects and more ability to overcome resistance.
Researchers from The University of Texas at Austin, The University of Texas MD Anderson Cancer Center and Austin-based biotech firm OncoTEX report their results this week in the journal Proceedings of the National Academy of Sciences.
Since 2005, millions of bats have perished from white-nose syndrome, a disease caused by the fungus Pseudogymnoascus destructans. Although the disease has been found throughout much of the world, severe population declines have only occurred in North America -- and now researchers at Virginia Tech know why.
Paleoclimate research offers an overview of Earth's climate change over the past 65 million years or longer and helps to improve our understanding of the Earth's climate system.
Unfortunately, our knowledge of weather-timescale extreme events (i.e., paleoweather occurring in days or even hours and minutes), such as tropical cyclones, cold/heat waves, and rainstorms under different climate conditions, is almost absent because current paleoclimatic reconstructions rarely provide information with temporal resolutions shorter than a month.
WOODS HOLE, Mass. -- It's not spring in New England until the herring are running. From late February to early April, two species of herring --alewife and blueback herring--return from the ocean and swarm the region's ponds and streams, seeking the waters in which they were born.
