For the brain to learn, retain memories, process sensory information, and coordinate body movements, its groups of nerve cells must generate coordinated electrical signals. Disorder in synchronous firing can impair these processes and, in extreme cases, lead to seizures and epilepsy.
Many policymakers and educational institutions hope to boost their economies by stimulating students' entrepreneurial intentions. To date, most research concluded that entrepreneurship education could increase these intentions by improving the image that students have of entrepreneurship as a career option, making them see how their environment can help them become entrepreneurs or increasing their self-confidence regarding their entrepreneurial skills. However, recent studies show that even if these goals are achieved, students' entrepreneurial intentions often do not grow.
HOUSTON - (Jan. 11, 2021) - Rice University scientists have extended their technique to produce graphene in a flash to tailor the properties of other 2D materials.
The labs of chemist James Tour and materials theorist Boris Yakobson reported in the American Chemical Society's ACS Nano they have successfully "flashed" bulk amounts of 2D dichalcogenides, changing them from semiconductors to metallics.
Such materials are valuable for electronics, catalysis and as lubricants, among other applications.
DURHAM, N.C. - A Duke-led team of scientists has developed a bio-compatible surgical patch that releases non-opioid painkillers directly to the site of a wound for days and then dissolves away.
The polymer patch provides a controlled release of a drug that blocks the enzyme COX-2 (cyclooxygenase-2,) which drives pain and inflammation. The study appears Jan. 10, 2021 in the Journal of Controlled Release.
University of Wyoming researchers headed a study that shows nonnative birds in Oahu, Hawaii, have taken over the role of seed dispersal networks on the island, with most of the seeds coming from nonnative plants.
Reston, Virginia--Physicians who follow artificial intelligence (AI) advice may be considered less liable for medical malpractice than is commonly thought, according to a new study of potential jury candidates in the U.S. Published in the January issue of The Journal of Nuclear Medicine (JNM). The study provides the first data related to physicians' potential liability for using AI in personalized medicine, which can often deviate from standard care.
'This effort truly represents a "moonshot" in COVID-19 research'
Scientists identify target to treat COVID pneumonia and reduce severity
Clinical trials with new experimental drug to begin early in 2021
Goal is to develop treatments that make COVID-19 no worse than a common cold
First comparison between immune mechanisms driving COVID-19 pneumonia with other pneumonias
ORLANDO, Jan. 11, 2021 - Data from Arecibo Observatory in Puerto Rico has been used to help detect the first possible hints of low-frequency disturbances in the curvature of space-time.
The results were presented today at the 237th meeting of the American Astronomical Society, which was held virtually, and are published in The Astrophysical Journal Letters. Arecibo Observatory is managed by the University of Central Florida for the National Science Foundation under a cooperative agreement.
Seeking to understand why COVID-19 is able to suppress the body’s immune response, new research from the USC Leonard Davis School of Gerontology suggests that mitochondria are one of the first lines of defense against COVID-19 and identifies key differences in how SARS-CoV-2, the virus that causes COVID-19, affects mitochondrial genes when compared to other viruses.
A new study shows that the gigantic Megalodon or megatooth shark, which lived nearly worldwide roughly 15-3.6 million years ago and reached at least 50 feet (15 meters) in length, gave birth to babies larger than most adult humans.
This latest research shedding light on the reproductive biology, growth and life expectancy of Megalodon (formally called Otodus megalodon) appears in the international journal Historical Biology.
ATLANTA AND TAMPA, FLA. - JANUARY 11, 2021 - A new study suggests a link between toxoplasma gondii (T. gondii) infection and the risk of glioma, a type of brain cancer, in adults. The report, appearing in the International Journal of Cancer, finds that people who have glioma are more likely to have antibodies to T. gondii (indicating that they have had a previous infection) than a similar group that was cancer free.
Fieldwork led by Dr Eleanor Scerri, head of the Pan-African Evolution Research Group at the Max Planck Institute for the Science of Human History in Germany and Dr Khady Niang of the University of Cheikh Anta Diop in Senegal, has documented the youngest known occurrence of the Middle Stone Age.
A new risk-stratification tool which can accurately predict the likelihood of deterioration in adults hospitalised with COVID-19 has been developed by researchers from the UK Coronavirus Clinical Characterisation Consortium (known as ISARIC4C).
Researchers say the online tool, made freely available to NHS doctors from today (Friday 8 January 2021), could support clinicians' decision making - helping to improve patient outcomes and ultimately save lives.
Study of 1,733 patients first diagnosed in Wuhan (China) between January and May followed to June and September.
76% of COVID-19 patients have at least one symptom six months after symptom onset.
Fatigue or muscle weakness is the most common symptom, with sleep difficulties and anxiety or depression also frequently reported.
Lower antibodies against COVID-19 in patients six months after becoming ill compared with during acute infection raises concerns about the possibility of re-infection.
Hundreds of cancer patients have benefitted from using computer algorithms to manage their symptoms and improve their wellbeing in a unique UK trial.
The early stage colorectal, breast or gynecological cancer patients took part in the trial of the eRAPID system, developed by the University of Leeds, which allowed them to report online symptoms from home and receive instant advice on whether to self-manage or seek medical attention.
