CHAMPAIGN, Ill. -- A new coronavirus test can get accurate results from a saliva sample in less than 30 minutes, researchers report in the journal Nature Communications. Many of the components of the hand-held device used in this technology can be 3D-printed, and the test can detect as little as one viral particle per 1-microliter drop of fluid.
A new study published in Nature Communications provides an important new basis for comparing the effectiveness of different tuberculosis treatments.
Tuberculosis, a disease caused by the bacterium Mycobacterium tuberculosis (Mtb), is typically the leading infectious cause of death globally, killing 1.2 million people each year. The availability of a new way to evaluate treatments can save lives.
Ants are renowned in the insect world for their complex social structure and behaviors. Workers and foragers support the queen, faithfully carrying out their social roles for the overall health of the colony. This complex "superorganism" ---as scientists have dubbed it --- has become a prime model to explore the genetic and behavioral roots of social organisms.
Remarkably, there are also rare instances of ants not playing well with others and shrugging off their societal duties to become free-loading parasites amongst their free-living relatives.
Optimistic predictions expect reliable autonomous vehicles to be commercially available by 2030, at a time when mobility is undergoing a profound shift away from traditional modes of transportation and towards door-to-door services. Previous analysis suggested that public transport will lose market share to autonomous vehicles, but the environmental impact of changing transport use has hardly been considered. New research shows that the convenience of autonomous vehicles would likely come at an environmental cost.
Information flows in a well-defined direction in the brain: Chemical and electrical signals are passed from one neuron to the other across the synapse, from the pre-synaptic to the post-synaptic neuron. Now, Peter Jonas and his group at the Institute of Science and Technology Austria (IST Austria) show that information also travels in the opposite direction at a key synapse in the hippocampus, the brain region responsible for learning and memory.
PULLMAN, Wash. - Alterations in the epigenetic programming of hatchery-raised steelhead trout could account for their reduced fertility, abnormal health and lower survival rates compared to wild fish, according to a new Washington State University study.
The study, published May 18 in Environmental Epigenetics, establishes a link between feeding practices that promote faster growth, as well as other environmental factors in fish hatcheries, and epigenetic changes found in the sperm and red blood cells of of steelhead trout.
A study using a mouse model of eccentric contraction (*1) has revealed that icing injured muscles delays muscle regeneration. The discovery was made by a research group including Associate Professor ARAKAWA Takamitsu and then PhD. Student KAWASHIMA Masato from Kobe University's Graduate School of Health Sciences, and Chiba Institute of Technology's Associate Professor KAWANISHI Noriaki et al. In addition, the researchers illuminated that this phenomenon may be related to pro-inflammatory macrophages' (*2, 3, 4) ability to infiltrate damaged cells.
Robust data and genetic research are providing important evidence on a colony of wild African vervet monkeys that landed in Dania Beach more than 70 years ago and settled in a thick mangrove forest near the Fort Lauderdale-Hollywood International Airport in South Florida.
Scientists from Hokkaido University have developed a rapid, efficient protocol for cross-coupling reactions, vastly expanding the pool of chemicals that can be used for the synthesis of useful organic compounds.
Vaccines are turning the tide of the pandemic, but the risk of infection is still present in some situations. If you want to visit a friend, get on a plane, or go see a movie, there is no highly accurate, instant test that can tell you right then and there whether or not you have a SARS-CoV-2 infection. But new research from Lawrence Berkeley National Laboratory (Berkeley Lab) could help get reliable instant tests on the market.
DETROIT (May 17, 2021) - A national study on childhood asthma led by Henry Ford Health System has found that family history, race and sex are associated in different ways with higher rates of asthma in children.
Archaeologists at Northern Arizona University are hoping a new technology they helped pioneer will change the way scientists study the broken pieces left behind by ancient societies.
The development of dementia, often from Alzheimer's disease, late in life is associated with abnormal blood levels of dozens of proteins up to five years earlier, according to a new study led by researchers at the Johns Hopkins Bloomberg School of Public Health. Most of these proteins were not known to be linked to dementia before, suggesting new targets for prevention therapies.
May 16, 2021 -- In a study of low-income, urban youth in the U.S., researchers at Columbia University Mailman School of Public Health found that students exposed to Photovoice, an educational intervention, experienced greater improvements in STEM-capacity scores and environmental awareness scores compared to a group of youth who were not exposed to the activity. The results suggest that the Photovoice activities may be associated with improved learning outcomes. The study is published in the International Journal of Qualitative Methods.
KINGSTON, R.I. - May 17, 2021 - An article recently published in the prestigious journal Nature Communications, written by University of Rhode Island College of Engineering Professor Stéphan Grilli and his colleagues, reveals new data on the Anak Krakatau volcano flank collapse, which was triggered by an eruption on December 22, 2018.
The tsunami created by the flank collapse hit the coast of Indonesia with waves as tall as 5 meters, leaving 420 people dead and 40,000 people displaced from their homes.
