New Edith Cowan University (ECU) research has found that intensive therapy is not necessarily best when it comes to treating the loss of language and communication in early recovery after a stroke.
Published today in the International Journal of Stroke, the research found that unlike physical and motor skill rehabilitation, recovering lost language caused by a condition known as aphasia after stroke is a marathon, not a sprint. It also showed that early intervention is crucial.
Rock-melting forces occurring much deeper in the Earth than previously understood appear to drive tremors along a notorious segment of California's San Andreas Fault, according to new USC research that helps explain how quakes happen.
Early identification and treatment is vital to avoid long-term mental health consequences from COVID-19 among children and young people, say researchers.
DURHAM, N.C. -- Materials scientists at Duke University have uncovered an atomic mechanism that makes certain thermoelectric materials incredibly efficient near high-temperature phase transitions. The information will help fill critical knowledge gaps in the computational modeling of such materials, potentially allowing researchers to discover new and better options for technologies that rely on transforming heat into electricity.
The results appear online on September 4 in the journal Nature Communications.
Scientists from the Skolkovo Institute of Science and Technology (Skoltech), Institute of Solid State Chemistry and Mechanochemistry (ISSC SB RAS), Pirogov Medical University and Yerevan State University have predicted new hard and superhard ternary compounds in the tungsten-molybdenum-boron system using computational methods. Their research was published in the journal Chemistry of Materials.
By shining white light on a glass slide stippled with millions of tiny titanium dioxide pillars, researchers at the National Institute of Standards and Technology (NIST) and their collaborators have reproduced with astonishing fidelity the luminous hues and subtle shadings of "Girl With a Pearl Earring," Dutch artist Johannes Vermeer's masterpiece. The approach has potential applications in improving optical communications and making currency harder to counterfeit.
Quantum bits, or qubits, can hold quantum information much longer now thanks to efforts by an international research team. The researchers have increased the retention time, or coherence time, to 10 milliseconds - 10,000 times longer than the previous record - by combining the orbital motion and spinning inside an atom. Such a boost in information retention has major implications for information technology developments since the longer coherence time makes spin-orbit qubits the ideal candidate for building large quantum computers.
Single-atom catalysts (SACs) are promising in electrocatalysis processes due to their maximum utilization of active species.
However, manipulation of these atomic-scale active sites to satisfy specific reactions is still an essential bottleneck due to their isolation features.
Tropical Depression Omar is one stubborn storm. Since it developed early in the week, it was being affected by wind shear. That wind shear has not let up by the week's end, and NASA satellite imagery showed the bulk of storms were being pushed to the southeast of the center.
NASA's Aqua Satellite Reveals Effects of Wind Shear
NASA's Aqua satellite uses infrared light to analyze the strength of storms by providing temperature information about the system's clouds. The strongest thunderstorms that reach high into the atmosphere have the coldest cloud top temperatures.
When we watch a movie or hear an orchestra playing, it seems that we perceive images and sounds as a continuous stream of information. But a new study suggests that the brain makes information conscious only at certain moments of time, which are preceded by intervals of unconscious processing that can last up to half a second.
The model, detailed in Trends in Cognitive Sciences, resolves longstanding debates about how consciousness arises and offers a new picture of how the brain becomes aware of information.
Experiencing reality
NASA's Terra satellite provided a visible image that showed Tropical Storm Omar had weakened to a depression as it continued to be battered by strong upper level winds.

DALLAS - Sept. 3, 2020 - A new technology that allows researchers to peer inside malignant tumors shows that two experimental drugs can normalize aberrant blood vessels, oxygenation, and other aspects of the tumor microenvironment in non-small cell lung cancer (NSCLC), helping to suppress the tumor's growth and spread, UT Southwestern researchers report.
Boston, Mass. - Most people with COVID-19 have relatively mild disease, but a subset of people develop severe pneumonia and respiratory failure, potentially leading to death. Beth Israel Deaconess Medical Center (BIDMC) immunologist Dan H. Barouch, MD, PhD, and colleagues showed in recently published previous work that a candidate COVID-19 vaccine raised neutralizing antibodies that robustly protected non-human primates (NHPs) against SARS-CoV-2, the virus that causes COVID-19.
Distinctive thermal and electrical characteristics make silver nanoparticles perfect for optics and biosensing applications. One increasingly popular application for the nanoparticles is as an antibacterial coating. Silver nanoparticle coatings are used in fabrics, footwear, computer keyboards, and orthopedic and other biomedical devices.
In mummified specimens, DNA has often degraded and is present only in minimal amounts. In fact, faced with a new discovery, the first question experts encounter is how to examine the mummy while continuing to preserve it, without damaging its ancient DNA. Every action has irreversible consequences on DNA fragments, which makes experimenting with new techniques on human finds impossible.
