Children with a common but regularly undiagnosed disorder affecting their language and communication are likely to be finding the transition back to school post-lockdown harder than most, according to a team of psychologists.
Two children in every class of 30 are estimated to have Developmental Language Disorder (DLD) (around 8%), yet public awareness, diagnosis and referral to speech and language therapists all remain low in the UK.
Superalloys that withstand extremely high temperatures could soon be tuned even more finely for specific properties such as mechanical strength, as a result of new findings published today.
A phenomenon related to the invar effect - which enables magnetic materials such as nickel-iron (Ni-Fe) alloys to keep from expanding with increasing temperature - was reported to have been discovered in paramagnetic, or weakly magnetized, high-temperature alloys.
University of Rochester researchers who demonstrated superconducting materials at room temperatures last fall, now report a new technique in the quest to also create the materials at lower pressures.
In a paper published in Physical Review Letters, the lab of Ranga Dias, assistant professor of mechanical engineering and of physics and astronomy, describes separating hydrogen atoms from yttrium with a thin film of palladium.
"This is a completely new technique that nobody has used before for high pressure superhydride synthesis," Dias says.
A team from the Universitat Politècnica de València (UPV) and the CIBER Bioengineering, Biomaterials and Nanomedicine (CIBER-BBN) has designed and tested, at a preclinical level, a new biomaterial for the treatment and recovery of muscle injuries. It is a boron-loaded alginate hydrogel, which would be administered with a subcutaneous injection. According to the tests carried out so far -in animal models-, it is capable of regenerating damaged muscle very rapidly -specifically, in half the time it takes for it to regenerate naturally.
Philadelphia, March 31, 2021 - In an article appearing in the Journal of Dairy Science®, scientists from the United States Department of Agriculture and the Council on Dairy Cattle Breeding provide an insightful review of how US dairy industry breeding selection objectives are established, as well as detail opportunities and obstacles related to new technologies for documenting an
Local alternative seafood networks (ASNs) in the United States and Canada, often considered niche segments, experienced unprecedented growth in the early months of the COVID-19 pandemic while the broader seafood system faltered, highlighting the need for greater functional diversity in supply chains, according to a new international study led by the University of Maine.
WASHINGTON, March 31, 2021 -- As environmental and energy crises become increasingly more common occurrences around the world, a thermal energy harvester capable of converting abundant thermal energy -- such as solar radiation, waste heat, combustion of biomass, or geothermal energy -- into mechanical energy appears to be a promising energy strategy to mitigate many crises.
Scientists have developed vaccines for COVID-19 with record speed. The first two vaccines widely distributed in the U.S. are mRNA-based and require ultracold storage (-70 C for one and -20 C for the other). Now, researchers reporting in ACS Omega have developed a tamper-proof temperature indicator that can alert health care workers when a vial of vaccine reaches an unsafe temperature for a certain period, which could help ensure distribution of effective mRNA vaccines.
LAWRENCE -- New research from the University of Kansas published in Earth-Science Reviews offers insight into one of the world's most powerful monsoon systems: the Indian summer monsoon. The study details how the monsoon, of vital social and economic importance to the people of the region, is supercharged by atmospheric dust particles swept up by winds from deserts in the Middle East.
Meat and fish fraud are global problems, costing consumers billions of dollars every year. On top of that, mislabeling products can cause problems for people with allergies, religious or cultural restrictions. Current methods to detect this fraud, while accurate, are slower than inspectors would like. Now, researchers reporting in ACS' Journal of Agricultural and Food Chemistry have optimized their handheld MasSpec Pen to identify common types of meat and fish within 15 seconds.
Every day, people are exposed to microplastics from food, water, beverages and air. But it's unclear just how many of these particles accumulate in the human body, and whether they pose health risks. Now, researchers reporting in ACS' Environmental Science & Technology have developed a lifetime microplastic exposure model that accounts for variable levels from different sources and in different populations. The new model indicates a lower average mass of microplastic accumulation than previous estimates.
Glass, rubber and plastics all belong to a class of matter called amorphous solids. And in spite of how common they are in our everyday lives, amorphous solids have long posed a challenge to scientists.
Neuroscientists agree that a person's brain is constantly changing, rewiring itself and adapting to environmental stimuli. This is how humans learn new things and create memories. This adaptability and malleability is called plasticity. "Physicians have long suspected that remodeling processes also take place in humans at the contact points between nerve cells, i.e. directly at the synapses. Until now, however, such a coordinated adaptation of structure and function could only be demonstrated in animal experiments," says Prof. Dr.
Using complementary computing calculations and neutron scattering techniques, researchers from the Department of Energy's Oak Ridge and Lawrence Berkeley national laboratories and the University of California, Berkeley, discovered the existence of an elusive type of spin dynamics in a quantum mechanical system.
LOWELL, Mass. - Researchers studying mercury gas in the atmosphere with the aim of reducing the pollutant worldwide have determined a vast amount of the toxic element is absorbed by plants, leading it to deposit into soils.
