CHAMPAIGN, Ill. -- Researchers report that they have developed a method to combine three brain-imaging techniques to more precisely capture the timing and location of brain responses to a stimulus. Their study is the first to combine the three widely used technologies for simultaneous imaging of brain activity. The work is reported in the journal Human Brain Mapping.
The new "trimodal" approach combines functional MRI, electroencephalography and a third technique, called EROS, that tracks the activity of neurons near the surface of the brain using near-infrared light.
Rare-earth elements are in many everyday products, such as smart phones, LED lights and batteries. However, only a few locations have large enough deposits worth mining, resulting in global supply chain tensions. So, there's a push toward recycling them from non-traditional sources, such as waste from burning coal -- fly ash. Now, researchers in ACS' Environmental Science & Technology report a simple method for recovering these elements from coal fly ash using an ionic liquid.
Results of the MOSAiC expedition show: the expected recovery of the ozone layer may fail to happen anytime soon, if global warming is not slowed down
Researchers at Karolinska Institutet in Sweden have developed a technology for cost-effective surveillance of the global spread of new SARS-CoV-2 variants. The technique is presented in the scientific journal Nature Communications.
Since the onset of the pandemic, thousands of viral genomes have been sequenced to reconstruct the evolution and global spread of the coronavirus. This is important for the identification of particularly concerning variants that are more contagious, pathogenic, or resistant to the existing vaccines.
The origins of seven types of kidney cancer, including several rare subtypes, have been identified by researchers at the Wellcome Sanger Institute, Great Ormond Street Hospital (GOSH), the Princess Máxima Center for Pediatric Oncology and Oncode Institute. The findings confirm that these cancers have their origin in specific forms of developmental cells present in the maturing fetus.
Chronic psychosocial stress--which involves a pathway called the hypothalamic-pituitary-adrenal axis (HPA axis)--may contribute to the development of Alzheimer's disease. A new review published in Biological Reviews describes how environmental and genetic factors can impact individuals' HPA axis, and ultimately their risk of Alzheimer's disease.
In a study published in the Journal of Bone and Mineral Research, investigators developed and validated a genetic risk score for predicting the onset and severity of the most common type of scoliosis in adolescents--called adolescent idiopathic scoliosis (AIS). AIS causes spinal deformities in as many as 3% of youth, and because its heritability is high, genetic data could help improve detection.
Viral mutations during the COVID-19 pandemic could cause the SARS-CoV-2 virus to become more dangerous. A new study published in Genetic Epidemiology has examined the genetic code of SARS-CoV-2 viruses that have infected patients, looking for links between different mutations and patient deaths.
New research published in the Journal of Cellular and Molecular Medicine indicates that SARS-CoV-2, the virus that causes COVID-19, produces microRNAs that can have impacts on infected cells. MicroRNAs are genetic molecules that prevent the production of particular proteins by binding to and destroying messenger RNAs that code for those proteins.
An article published in the Journal of School Health stresses that food literacy--understanding the impact of food choices on our health, environment, and economy--should be a priority for K-12 schools during the COVID-19 pandemic and beyond.
Boston, MA - Using genome-wide association studies (GWAS) methodology to analyze whole-genome sequencing data of SARS-CoV-2 mutations and COVID-19 mortality data can identify highly pathogenic variants of the virus that should be flagged for containment, according to Harvard T.H. Chan School of Public Health and MIT researchers.
A new United Nations report calls for an urgent change in the way the world's oceans are managed.
The report from the International Resource Panel, hosted by the UN Environment Programme, raises concerns that if changes are not made quickly, the consequences will be dire.
The Governing Coastal Resources Report was launched today at an event addressed by Ambassador Peter Thomson, UN Secretary-General's Special Envoy for the Ocean. It outlines the effect land-based human activities have on the marine environment.
Using data for more than 500 young stars observed with the Atacama Large Millimeter/Submillimeter Array (ALMA), scientists have uncovered a direct link between protoplanetary disk structures--the planet-forming disks that surround stars--and planet demographics. The survey proves that higher mass stars are more likely to be surrounded by disks with "gaps" in them and that these gaps directly correlate to the high occurrence of observed giant exoplanets around such stars.
A new UC Riverside study finds geckos are fierce hunters whether or not their tails are attached to their bodies.
Geckos and other lizards can distract predators by quickly dropping their tails. The tail vertebrae are perforated, making it easier to disconnect them without any formation of scar tissue or loss of blood. Though this ability can keep lizards from being eaten, the maneuver is performed at a cost.
COLUMBUS, Ohio - Americans consistently believe that poor African Americans are more likely to move up the economic ladder than they actually are, a new study shows.
People also overestimate how likely poor white people are to get ahead economically, but to a much lesser extent than they do for Black people.
"It's no surprise that most people in our society believe in the American Dream of working hard and succeeding economically," said Jesse Walker, co-author of the study and assistant professor of marketing at The Ohio State University's Fisher College of Business.
