Researchers at Harvard University and the Broad Institute of MIT and Harvard have created a first detailed atlas of a critical region of the developing mouse brain, applying multiple advanced genomic technologies to the part of the cerebral cortex that is responsible for processing sensation from the body. By measuring how gene activity and regulation change over time, researchers now have a better understanding of how the cerebral cortex is built, as well as a brand new set of tools to explore how the cortex is affected in neurodevelopmental disease.
Indonesia's volcanoes are among the world's most dangerous. Why? Through chemical analyses of tiny minerals in lava from Bali and Java, researchers from Uppsala University and elsewhere have found new clues. They now understand better how the Earth's mantle is composed in that particular region and how the magma changes before an eruption. The study is published in Nature Communications.
Frances Deegan, the study's first author and a researcher at Uppsala University's Department of Earth Sciences, summarises the findings.
Philadelphia, June 24, 2021 - Women with depression and other mood disorders are generally advised to continue taking antidepressant medications during pregnancy. The drugs are widely considered safe, but the effect of these medications on the unborn fetus has remained a topic of some concern.
Supercomputers could find themselves out of a job thanks to a suite of new machine learning models that produce rapid, accurate results using a normal laptop.
Researchers at the ARC Centre of Excellence in Exciton Science, based at RMIT University, have written a program that predicts the band gap of materials, including for solar energy applications, via freely available and easy-to-use software. Band gap is a crucial indication of how efficient a material will be when designing new solar cells.
Our planet is warming due to anthropogenic greenhouse gas emissions; but the warming differs from region to region, and it can also vary seasonally. Over the last four decades scientists have observed a persistent austral summer cooling on the eastern side of Antarctica. This puzzling feature has received world-wide attention, because it is not far away from one of the well-known global warming hotspots - the Antarctic Peninsula.
Research Associate Artyom Gusarov studied a vast array of erosion data to make a general takeaway that soil erosion and river sediment load in the aforementioned region has significantly decreased throughout the post-Soviet period.
Organic solar elements with the self-assembling molecular-thin layer (SAM) of hole-transporting material, the technology, which was used in producing a record-breaking tandem solar cell, achieved 18.4 power conversion efficiency. The invention of Lithuanian chemists working at Kaunas University of Technology (KTU), commercialized by several global companies proved versatile and applicable to different solar technologies.
A research collaboration based in Kumamoto University (Japan) has identified a novel lncRNA, Caren, that is abundantly expressed in cardiomyocytes. They showed that it enhances energy production by increasing the number of mitochondria in cardiomyocytes, and inhibits activation of the ATM protein, a key player in the DNA damage response pathway that accelerates heart failure severity.
Children who were exposed to higher levels of trace minerals manganese and selenium during their mothers' pregnancy had a lower risk of high blood pressure in childhood, according to a study led by researchers at the Johns Hopkins Bloomberg School of Public Health.
A new study from archaeologists at University of Sydney and Simon Fraser University in Vancouver, has provided important new evidence to answer the question "Who exactly were the Anglo-Saxons?"
New findings based on studying skeletal remains clearly indicates the Anglo-Saxons were a melting pot of people from both migrant and local cultural groups and not one homogenous group from Western Europe.
For patients who have inflammatory bowel syndrome (IBS), the condition is literally a pain in the gut. Chronic -- or long-term -- abdominal pain is common, and there are currently no effective treatment options for this debilitating symptom. In a new study in ACS Pharmacology & Translational Science, researchers identify a new potential source of relief: a molecule derived from spider venom. In experiments with mice, they found that one dose could stop symptoms associated with IBS pain.
Previous research was falsely reassuring; captured only 2% of cirrhosis patients
Findings underscore lack of access to health care for Black patients
Cirrhosis is leading cause of death and affects more than 600,000 people in U.S.
CHICAGO --- Black patients with cirrhosis - late-stage liver disease - are about 25% more likely to die compared to non-Hispanic white patients and four times less likely to receive a liver transplant, reports a new Northwestern Medicine study.
A new biocompatible polymer-based composite material could soon replace metal plates in treating difficult and unstable fractures. Developed at KTH Royal Institute of Technology in Stockholm, the newly-developed material is as strong as dental composites yet non-toxic.
The material and a surgical method, which were published in Advanced Functional Materials, will be used in clinical studies in 2023 and 2024, with a focus on hand fractures.
In New England, constraints in the supply of natural gas have led to nearly a quarter of all unscheduled power plant outages. In a new study, researchers used data from power plant failures in the 2010s to develop a supply curve of the costs required for generators to mitigate fuel shortages in the region. The study found that storing both oil and gas on-site could reduce dependence by power plants on gas grids in geographic areas with few pipelines.
BROOKLYN, New York, Wednesday, June 23, 2021 -- Owing to their tunable properties, hydrogels comprising stimuli-sensitive polymers are among the most appealing molecular scaffolds because their versatility allows for applications in tissue engineering, drug delivery and other biomedical fields.
