Machine learning for solar energy is supercomputer kryptonite

Eurekalert - Jun 23 2021 - 00:06
Supercomputers may no longer be needed to screen candidate materials and perform simulations for a wide variety of theoretical and commercial applications thanks to an easily accessible and computationally inexpensive new machine learning model, which has been initially trained to predict the band gap of solar energy materials as a proof of concept.

Systolic blood pressure above 120 mmHg increases rate of cardiovascular disease

Eurekalert - Jun 23 2021 - 00:06
Researchers remain perplexed on the role of the interplay between blood pressure and glucose status and the development of cardiovascular events like coronary artery disease and cerebrovascular disease. In a first-of-its-kind study, published in Diabetes Care, Japanese researchers discovered that cardiovascular risks gradually rose with increases in blood pressure regardless of the presence of and degree of a blood glucose abnormality -- providing insight on BP targets for hypertensive patients according to glucose status.

Long COVID symptoms likely caused by Epstein-Barr virus reactivation

Eurekalert - Jun 23 2021 - 00:06
Epstein-Barr virus (EBV) reactivation may be the cause of previously unexplained long COVID symptoms -- such as fatigue, brain fog, and rashes -- that occur in approximately 30% of patients after recovery from initial COVID-19 infection. The first evidence linking EBV reactivation to long COVID, as well as an analysis of long COVID prevalence, is outlined in a new long COVID study published in the journal Pathogens.

Virtual training helps underserved middle schoolers hone social skills

Eurekalert - Jun 23 2021 - 00:06
Middle school, a time when children's brains are undergoing significant development, is often also a time of new challenges in navigating the social world. Recent research from the Center for BrainHealth at UT Dallas demonstrates the power of combining a virtual platform with live coaching to help students enhance their social skills and confidence in a low-risk environment.

Declining treatment during maternity care can foster tension between patients and providers

Eurekalert - Jun 23 2021 - 00:06
When a pregnant person declines a recommended treatment such as prenatal testing or an epidural, tension and strife may ensue between the patient and provider, according to a new analysis by researchers at NYU Rory Meyers College of Nursing and the University of British Columbia.

Bourneville's tuberous sclerosis: everything unfolds in the brain shortly after birth

Eurekalert - Jun 23 2021 - 00:06
By disrupting postnatal development in GABAergic interneurons, a genetic mutation appears to be at the origin of the neurological disorders associated with a disease affecting one in 6,000 children.

Use of tobacco pipes by Native groups tells story of regional diversity

Eurekalert - Jun 23 2021 - 00:06
Nineteenth- and 20th-century archaeologists often made sweeping claims about Native cultures, suggesting that everyone who lived in a particular region at a given time shared the same attitudes and practices. A new study of pipes recovered from Hopewell sites in Illinois and Ohio challenges this assumption, revealing that the manufacture, import, export and use of pipestone pipes for smoking varied significantly between the groups, even though they engaged in trade with one another.

Language trade-off? No, bilingual children reliably acquire English by age 5

Eurekalert - Jun 23 2021 - 00:06
A first-of-its kind study in U.S.-born children from Spanish-speaking families finds that minority language exposure does not threaten the acquisition of English by children in the U.S. and that there is no trade-off between English and Spanish. Rather, children reliably acquire English by age 5, and their total language knowledge is greater to the degree that they also acquire Spanish. Children's level of English knowledge was independent of their level of Spanish knowledge.

People overestimate Black Americans' chances of economic success

Eurekalert - Jun 23 2021 - 00:06
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.

Mind the gap: Scientists use stellar mass to link exoplanets to planet-forming disks

Eurekalert - Jun 23 2021 - 00:06
Data from 500 young stars observed with the Atacama Large Millimeter/submilliter Array (ALMA) is giving scientists a window back through time, allowing them to predict what exoplanetary systems looked like through each stage of their formation. And it all starts with a link between higher mass stars, disks with gaps in them, and a high occurrence of observed exoplanets.

Mining precious rare-earth elements from coal fly ash with a reusable ionic liquid

Eurekalert - Jun 23 2021 - 00:06
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.

Mapping methane sources in Paris

Eurekalert - Jun 23 2021 - 00:06
A potent greenhouse gas, methane is released by many sources, both human and natural. Large cities emit significant amounts of methane, but in many cases the exact emission sources are unknown. Now, researchers reporting in ACS' Environmental Science & Technology have conducted mobile measurements of methane and its sources throughout Paris. Their findings suggest that the natural gas distribution network, the sewage system and furnaces of buildings are ideal targets for methane reduction efforts.

Combining three techniques boosts brain-imaging precision

Eurekalert - Jun 23 2021 - 00:06
Researchers 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 - fMRI, EEG and EROS - for simultaneous imaging of brain activity.

Had COVID-19? One vaccine dose enough; boosters for all, study says

Eurekalert - Jun 23 2021 - 00:06
Two mRNA vaccines against COVID-19 have proven safe and effective in clinical trials, as well as in the millions of people who have been vaccinated so far. But how prior SARS-CoV-2 infection affects vaccine response, and how long that response lasts, are still uncertain. Now, a new study in ACS Nano supports increasing evidence that people who had COVID-19 need only one vaccine dose, and that boosters could be necessary for everyone in the future.

Using virtual populations for clinical trials

Eurekalert - Jun 23 2021 - 00:06
A study involving virtual rather than real patients was as effective as traditional clinical trials in evaluating a medical device used to treat brain aneurysms, according to new research. The findings are proof of concept for what are called in-silico trials, where instead of recruiting people to a real-life clinical trial, researchers build digital simulations of patient groups, loosely akin to the way virtual populations are built in The Sims computer game.
