In new research, Texas A&M University scientists have for the first time revealed a single microscopic defect called a "twin" in a soft-block copolymer using an advanced electron microscopy technique. This defect may be exploited in the future to create materials with novel acoustic and photonic properties.
Boulder, Colo., USA: The Paleozoic era culminated 251.9 million years ago in the most severe mass extinction recorded in the geologic record. Known as the "great dying," this event saw the loss of up to 96% of all marine species and around 70% of terrestrial species, including plants and insects.
A key driver of energy research is the ever-growing demand for energy. Traditional fossil-fuel-based energy sources currently meet these demands and do it well, but they're non-renewable and cause major environmental pollution. In a world with looming climate and resource crises threats, researchers have turned to renewable sources of energy as sustainable alternatives. Among renewables, wind energy, in particular, has gained considerable attention due to its low cost. As Dr.
WASHINGTON (May 19, 2021)--Early online support for the Boogaloos, one of the groups implicated in the January 2021 attack on the United States Capitol, followed the same mathematical pattern as ISIS, despite the stark ideological, geographical and cultural differences between their forms of extremism. That's the conclusion of a new study published today by researchers at the George Washington University.
While a pint-sized snorer may seem adorable tucked up in bed, studies shows that children with sleep disordered breathing are likely to show aggressive and hyperactive behaviours during the day.
The recommended treatment is an adenotonsillectomy - the removal of adenoid and tonsils - not only to fix the snore, but also the behaviour.
Yet according to new research from the University of South Australia, while the surgery can cure a child's snoring it doesn't change their behaviour, despite common misconceptions by parents and doctors alike.
Twice as many eligible patients got screened for hepatitis C when it was already ordered for them compared to those who had to request it, according to a new study by researchers at the Perelman School of Medicine at the University of Pennsylvania. Additionally, the patients in the study - whose average age was 63 - completed their screenings much more often when they were contacted via mail as opposed to electronic messaging. The study was published today in BMJ.
Ikoma, Japan - In neurons, changes in the size of dendritic spines - small cellular protrusions involved in synaptic transmission - are thought to be a key mechanism underlying learning and memory. However, the specific way in which these structural changes occur remains unknown. In a study published in Cell Reports, researchers from Nara Institute of Science and Technology (NAIST) have revealed that the binding of cell adhesion molecules with actin, via an important linker protein in the structural backbone of synapses, is vital for this process of structural plasticity.
Research to be published tomorrow in the journal Nature Communications is the first study to quantify the costs of storm damage caused by sea level rise driven specifically by human-induced climate change. Researchers from Stevens Institute of Technology, Climate Central, Rutgers University and other institutions found this self-inflicted damage to be $8.1 billion of Hurricane Sandy's damage and an additional 71,000 people and 36,000 homes exposed to Sandy's flooding.
BOSTON - Prompted by a recent alarming rise in cases of colorectal cancer in people younger than 50, an independent expert panel has recommended that individuals of average risk for the disease begin screening exams at 45 years of age instead of the traditional 50.
The guideline changes by the U.S. Preventive Services Task Force (USPSTF), published in the current issue of JAMA, updates its 2016 recommendations and aligns them with those of the American Cancer Society, which lowered the age for initiation of screening to 45 years in 2018.
Scientists led by Dr. Salvador Aznar-Benitah, head of the Stem Cells and Cancer laboratory at IRB Barcelona, have described the alterations that occur during mammary gland formation when heterochromatin (the part of DNA that does not actively produce proteins) is poorly regulated. The results, which have been published in the journal Cell Stem Cell, indicate that incorrect DNA packaging makes retrotransposons (a type of transposable element originated in ancestral fragments of viruses integrated into the cell genome) more accessible.
Fossils of land animals from South America have been found in the Antilles, but how did these animals get there? According to scientists from the CNRS, l'Université des Antilles, l'Université de Montpellier and d'Université Côte d'Azur, land emerged in this region and then disappeared beneath the waves for millions of years, explaining how some species were able to migrate to the Antilles. This study will be published in June 2021 issue in Earth-Science Reviews.
A University of Surrey project has revealed innovative methods that could dramatically improve the performance of future electrical vehicles (e-vehicles).
As part of the European Union's STEVE* project, Surrey has developed several pioneering approaches to torque vectoring in electric vehicles.
To support growing human and animal life, freshwater sources must continuously supply water. Freshwater from lakes, rivers, and underground is mainly recharged by rainfall. Ground reservoirs can store rainwater over time, depending on that location's storage capability. However, estimating freshwater storage capability (FSC) is still a challenge due to few observation opportunities and methods to measure and quantify FSC.
May 18, 2021 - Offering interventions to young people in the general community can prevent the emergence of certain mental health disorders, according to the first comprehensive systematic review to address this question.
As lockdown measures ease this week in the UK, environmental psychologists are urging that before rushing back to business as normal, we take advantage of the shifts observed over the past year to lock-in new, greener behaviours.
