Astronomers studying galaxy evolution have long struggled to understand what causes star formation to shut down in massive galaxies. Although many theories have been proposed to explain this process, known as "quenching," there is still no consensus on a satisfactory model.
Recent studies indicate HIV infection heightens the risk of dental cavities - but a Rutgers researcher has found evidence that the risk of cavities comes not from HIV itself but from a weakened immune system, which could be caused by other diseases.
Korea Brain Research Institute (KBRI headed by Suh Pann-ghill) announced the discovery of the elevation of Ace2 as a SARS-CoV-2 entry receptor gene expression in elderly patients with Alzheimer's by Dr. Joo Jae-yeol and Dr. Lim Key-hwan.
The research results were published in the online version of the Journal of Infection dated June 30, and the title and authors of the paper are as follows.
*Title: Elevation of Ace2 as a SARS-CoV-2 entry receptor gene expression in Alzheimer's disease
It seems the universe has an odd sense of humor. While a crown-encrusted virus has run roughshod over the world, another entirely different corona about 100 million light years from Earth has mysteriously disappeared.
For the first time, astronomers at MIT and elsewhere have watched as a supermassive black hole's own corona, the ultrabright, billion-degree ring of high-energy particles that encircles a black hole's event horizon, was abruptly destroyed.
Genes linked to ageing that could help explain why some people age at different rates to others have been identified by scientists.
The international study using genetic data from more than a million people suggests that maintaining healthy levels of iron in the blood could be a key to ageing better and living longer.
The findings could accelerate the development of drugs to reduce age-related diseases, extend healthy years of life and increase the chances of living to old age free of disease, the researchers say.
HOUSTON -- (July 16, 2020) -- Biology is rife with examples of collective behavior, from flocks of birds and colonies of bacteria to schools of fish and mobs of people. In a study with implications from oncology to ecology, researchers from Rice University and the University of Georgia have shown that data science can unlock subtle clues about the individual origins of collective behavior.
A majority of college students of color show symptoms of post-traumatic stress disorder after watching social media videos of unarmed Black men being killed by police, a Rutgers study finds.
The study, published in the Journal of Black Studies, surveyed 134 college students in the United States, between the ages of 18 and 24, 77 percent of whom were Black or Latinx.
A technique that maps a patient's language centers before going into surgery works best when their brain tumor is not in those areas. The finding, published by Nagoya University researchers in the journal Scientific Reports, refines understanding of the test's effectiveness and could help improve surgical planning.
In a boost for both recreational fishing and the environment, new UNSW research shows that artificial reefs can increase fish abundance in estuaries with little natural reef.
Researchers installed six manmade reefs per estuary studied and found overall fish abundance increased up to 20 times in each reef across a two-year period.
The study, published in the Journal of Applied Ecology recently, was funded by the NSW Recreational Fishing Trust.
An international team tracking the 'new physics' neutrinos has checked the data of all the relevant experiments associated with neutrino detections against Standard Model extensions proposed by theorists. The latest analysis, the first with such comprehensive coverage, shows the scale of challenges facing right-handed neutrino seekers, but also brings a spark of hope.
In a recent study, researchers at the Institute of Modern Physics (IMP) of the Chinese Academy of Science (CAS) and their collaborators reported the first discovery of 222Np, a new very short-lived neptunium (Np) isotope, and validated the N = 126 shell effect in Np isotopes.
The experiment, led by Prof. GAN Zaiguo of IMP, was carried out at the Heavy Ion Research Facility in Lanzhou. And the study was published in Physical Review Letters on July 13.
Since mRNAs play a key role in protein synthesis in vivo, the use of mRNAs as medicines and for in vitro protein synthesis has been desired. In particular, mRNA therapeutics hold the potential for application to vaccine therapy(1) against coronaviruses and are being developed. However, the efficiency of protein production with mRNAs in the natural form is not sufficient enough for certain purposes, including application to mRNA therapeutics. Therefore, mRNA molecules allowing for efficient protein production have been required to be developed.
The study by scientists from Duke-NUS Medical School, in close collaboration with the National University of Singapore (NUS) Yong Loo Lin School of Medicine, Singapore General Hospital (SGH) and National Centre for Infectious Diseases (NCID) was published in Nature. The findings suggest infection and exposure to coronaviruses induces long-lasting memory T cells, which could help in the management of the current pandemic and in vaccine development against COVID-19.
The vast universe can always arise people's infinite imagination and yearning. Black hole, as one of the most attractive heavenly bodies in the universe, are waiting to be explored and studied. However, due to the limitations of technology, human is still unable to go into the depths of universe, let alone reach the vicinity of a black hole.
"A lack of intensive care ventilation units owing to rapidly increasing infection rates numbers among the most significant nightmare scenarios of the corona pandemic," says Mathias Wirth, Head of the Ethics Department in the Faculty of Theology at the University of Bern, because: "Shortages of supply can result in triage of patients suffering from severe cases of COVID-19 and thus force a life or death decision." Here, triage means favoring some COVID-19 patients over others depending on urgency and prognosis.
