Alexandria, Va., USA -- COVID-19 was declared a global pandemic in March 2020 and given an incomplete understanding of the transmission of SARS-CoV-2 at that time, the American Dental Association recommended that dental offices refrain from providing non-emergency services. As a result, 198,000 dentists in the United States closed their doors to patients.
Are you empathic, generous and altruistic? In short, do you possess that specific personality trait defined as agreeableness in the language of psychologists? New research from SISSA recently published in the journal NeuroImage sheds light on brain mechanisms underlying this trait.
When Museums closed their doors in March 2020 for the first COVID-19 lockdown in the UK a majority moved their activities online to keep their audiences interested. Researchers from WMG, University of Warwick have worked with OUMNH, to analyse the success of the exhibitions, and say the way Museums operate will change forever.Caption: Compton Verney's homepage for the Cranach exhibition which opened in March 2020 Credit: Compton Verney
Surface plasmon polaritons (SPPs) are highly localized surface waves on the interface between metal and dielectric in the optical frequency band. SSPs do not naturally exist in the microwave and terahertz frequencies, so "spoof" surface plasmon polaritons (SSPPs) are necessary for operations in those lower frequency bands.
BOSTON - During the development and progression of Alzheimer's disease, a protein called tau accumulates and spreads in the brain. Understanding the mechanisms behind tau spread--and its consequences--may point to new prevention and treatment strategies for Alzheimer's disease and other forms of dementia. New insights now come from research that was led by investigators at Massachusetts General Hospital (MGH) and involves an anesthetic known to affect cognitive function.
NEW YORK, NY--While there was extensive use of drug repurposing throughout the first 10 months of the COVID-19 pandemic, there was substantial heterogeneity over the types of drugs used for treatment purposes globally. Some drugs, including hydroxychloroquine, saw sharp declines in use, while adjunctive therapies grew into a more relied upon method for patient management.
In a number of cases, scientific discovery overturned misconceptions proclaimed via press conferences and social media.
CHAMPAIGN, Ill. -- Young people with diverse gender identities may be bullied and victimized up to three times more often than peers who identify as male or female, a new study of more than 4,464 adolescents in Illinois found.
The students were part of a statewide survey of eighth- through 12th-grade youths in Illinois schools.
Can a protein found in a mosquito lead to a better understanding of the workings of our own brains? Prof. Ofer Yizhar and his team in the Weizmann Institute of Science's Neurobiology Department took a light-sensitive protein derived from mosquitos and used it to devise an improved method for investigating the messages that are passed from neuron to neuron in the brains of mice. This method, reported today in Neuron, could potentially help scientists solve age-old cerebral mysteries that could pave the way for new and improved therapies to treat neurological and psychiatric conditions.
EAST LANSING, Mich. - As climate change threatens global food security, researchers at Michigan State University are building better beans crucial to human nutrition by tapping into the genetics of the more heat-resistant tepary bean.
Severe symptoms of COVID-19, leading often to death, are thought to result from the patient's own acute immune response rather than from damage inflicted directly by the virus. Immense research efforts are therefore invested in figuring out how the virus manages to mount an effective invasion while throwing the immune system off course. A new study, published today in Nature, reveals a multipronged strategy that the virus employs to ensure its quick and efficient replication, while avoiding detection by the immune system. The joint labor of the research groups of Dr.
New science about the fate of freshwater ecosystems released today by the journal Sustainability finds that only 17 percent of rivers globally are both free-flowing and within protected areas, leaving many of these highly-threatened systems¬--and the species that rely on them --at risk.

If you're like many people, McDonald's, Wendy's, and Burger King may come to mind--even if you much prefer In-N-Out or Chick-fil-A.
Autoimmune diseases have something in common with horses, bachelor's degrees and daily flossing habits: women are more likely to have them.
One reason for autoimmune diseases' prevalence in women may be sex-based differences in inflammation. In a new study, West Virginia University researcher Jonathan Busada investigated how sex hormones affect stomach inflammation in males and females. He found that androgens--or male sex hormones--may help to keep stomach inflammation in check.
Brown bears that are more inclined to grate and rub against trees have more offspring and more mates, according to a University of Alberta study. The results suggest there might be a fitness component to the poorly understood behaviour.
"As far as we know, all bears do this dance, rubbing their back up against the trees, stomping the feet and leaving behind odours of who they are, what they are, what position they're in, and possibly whether they are related," said Mark Boyce, an ecologist in the Department of Biological Sciences.
The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) has helped Gaia achieve millimagnitude (mmag) precision in photometry, according to a study led by researchers from National Astronomical Observatories of Chinese Academy of Sciences (NAOC) and Beijing Normal University (BNU).
Their study was published in The Astrophysical Journal.
