Philadelphia, April 14, 2021 - In late 2020, several concerning SARS-CoV-2 variants emerged globally. They are believed to be more easily transmissible, and there is concern that some may reduce the effectiveness of antibody treatments and vaccines. An extensive genome sequencing program run by the Houston Methodist health system has identified all six of the currently identified SARS-CoV-2 variants in their patients.
A new study co-authored by University of Colorado Cancer Center researcher Srinivas Ramachandran, PhD, shows how DNA segments known as enhancers function in cells.
The paper published last month in Molecular Cell highlighted the work from Ramachandran, along with Satyanarayan Rao, both part of the Department of Biochemistry and Molecular Genetics at the CU School of Medicine, and Kami Ahmad from the Fred Hutchinson Cancer Research Center.
By Luciana Constantino | Agência FAPESP – Adults with periodontitis transmit bacteria that can cause the disease in future to their children, and the bacteria remain in the oral cavity even when the children undergo treatment of various kinds, reinforcing the need for preventive care in the first year of a baby’s life. This is the main conclusion of a study conducted at the University of Campinas (UNICAMP) in the state of São Paulo, Brazil.
HERSHEY, Pa. -- People who trust television and Facebook to provide them with accurate news about the coronavirus pandemic are less knowledgeable about COVID-19, according to a new study, which assessed people's knowledge of the virus in the earliest stages of the pandemic.
The study, published in the peer-reviewed journal Current Medical Research & Opinion, surveyed 5,948 adults in Pennsylvania between March 25-31, 2020, and found that those who relied on social media and TV for news were less likely to get the facts right about the coronavirus.
ITHACA, N.Y. - Just as humans are challenged from the social isolation caused by the coronavirus pandemic, a new study finds that a solitary lifestyle has profound effects on the brains of a social insect: paper wasps.
Paper wasps recognize the brightly colored faces of other paper wasps, an ability they lose when reared in isolation. The wasps' ability to remember faces is similar to primates and humans, but unlike other social insects.
Researchers from the HSE Center for Language and Brain https://www.hse.ru/en/neuroling/ have, for the first time, described the language abilities of Russian children with Autism Spectrum Disorder (ASD) at all linguistic levels (e.g., phonology, lexicon, morphosyntax, and discourse), using a language test that takes into account the psycholinguistic variables most relevant for Russians.
Ultralight bosons are hypothetical particles whose mass is predicted to be less than a billionth the mass of an electron. They interact relatively little with their surroundings and have thus far eluded searches to confirm their existence. If they exist, ultralight bosons such as axions would likely be a form of dark matter, the mysterious, invisible stuff that makes up 85 percent of the matter in the universe.
New research has found that the most reliable indicators of willingness to be vaccinated against SARS-CoV-2, the virus that causes COVID-19, are rejection of conspiracy suspicions about COVID-19 and a positive attitude towards vaccines in general. The study by King's College London and the University of Bristol is published in the leading peer-reviewed journal Psychological Medicine.
Irvine, CA - April 14, 2021 - A new study, led by the University of California, Irvine (UCI), reveals how chronic inflammation promotes muscle fibrosis, which could inform the development of new therapies for patients suffering from Duchenne muscular dystrophy (DMD), a fatal muscle disease.
New research published in Science Advances provides a template for how to develop directly-acting antivirals with novel modes of action, that would combat COVID-19 by suppressing the SARS-CoV-2 viral infection. The study focused on the macrodomain part of the Nsp3 gene product that SARS-CoV-2 uses to suppress the host cell's natural antiviral response.
"Family clustering is a confirmed phenomenon associated with Covid-19, and harrowing stories of this disease ravaging families continue to be reported," a new article explains in the March-April issue of the Hastings Center Report. In one extreme example, 28 extended family members in California reportedly tested positive for Covid-19. Two of the family members who quarantined together required hospitalization, and one of them died from the infection.
The slurred speech, poor coordination, and sedative effects of drinking too much alcohol may actually be caused by the breakdown of alcohol products produced in the brain, not in the liver as scientists currently think. That is the finding of a new study led by researchers from the University of Maryland School of Medicine (UMSOM) and the National Institute on Alcohol Abuse and Alcoholism. It was published recently in the journal Nature Metabolism and provides new insights into how alcohol may affect the brain and the potential for new treatments to treat alcohol misuse.
Most people by now have memorized the public health guidelines meant to help minimize transmission of COVID-19: wash your hands, wear a mask, keep six feet apart from others. That part is easy.
What some may not realize is that upholding these guidelines in certain urban areas can present new challenges.
To better understand how RNA in bacteria gives rise to protein--and along the way, target these processes in the design of new antibiotics--researchers are turning their attention to the unique way this process happens in bacteria.
