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.
More than half of Latina mothers surveyed in Yolo and Sacramento counties reported making economic cutbacks in response to the pandemic shutdown last spring -- saying they bought less food and missed rent payments. Even for mothers who reported receiving the federal stimulus payment during this time, these hardships were not reduced, University of California, Davis, researchers found in a recent study.
ORLANDO, Jan. 8, 2021 - Florida's threatened coral reefs have a more than $4 billion annual economic impact on the state's economy, and University of Central Florida researchers are zeroing in on one factor that could be limiting their survival - coral skeleton strength.
In a new study published in the journal Coral Reefs, UCF engineering researchers tested how well staghorn coral skeletons withstand the forces of nature and humans, such as impacts from hurricanes and divers.
COVID-19 patients admitted to intensive care in the early months of the pandemic were subject to a significantly higher burden of delirium and coma than is typically found in patients with acute respiratory failure. Choice of sedative medications and curbs on family visitation played a role in increasing acute brain dysfunction for these patients.
That's according to an international study published Jan. 8 in The Lancet Respiratory Medicine, led by researchers at Vanderbilt University Medical Center in coordination with researchers in Spain.
Eating a healthy diet, such as the Mediterranean diet, has a positive impact on health, but little is known about the effects of including unhealthy foods in an otherwise healthy diet. Now researchers at Rush University Medical Center have reported diminished benefits of a Mediterranean diet among those with high frequency of eating unhealthy foods. The results of their study were published in Alzheimer's & Dementia: The Journal of the Alzheimer's Association on Jan. 7.
