Massive galaxies were already much more mature in the early universe than previously expected. This is the conclusion of an international team of astronomers who studied distant galaxies with the Atacama Large Millimeter/submillimeter Array (ALMA). The result is now published by the National Radio Astronomy Observatory.
This ethereal remnant of a long dead star, nestled in the belly of The Whale, bears an uneasy resemblance to a skull floating through space. Captured in astounding detail by ESO's Very Large Telescope (VLT), the eerie Skull Nebula is showcased in this new image in beautiful bloodshot colours. This planetary nebula is the first known to be associated with a pair of closely bound stars orbited by a third outer star.
A pair of University of Michigan studies reveals how some massive stars--stars eight or more times the mass of our sun--become isolated in the universe: most often, their star clusters kick them out.
Massive stars typically reside in clusters. Isolated massive stars are called field massive stars. The papers published by U-M students examined most of these stars in the Small Magellanic Cloud, a dwarf galaxy near the Milky Way.
Researchers at the RIKEN Center for Biosystems Dynamics Research (BDR) have developed an improved human-skin equivalent that reproduces traction-force balance in the lateral direction, a property that controls the structure and physiological function of skin. This artificial skin will enhance in-depth analyses of physiological skin functions, provide solutions to skin problems caused by diseases or ageing, and reduce the need for animal testing.
How does Covid-19 affect sperm and thus the next generation´s immune system? Researchers from the University of Bergen are collecting sperm to find the answer.
So far, 50 Covid-19 patients between 30 and 40 have delivered a sperm sample. Students are next in line. The plan is that participants will return after 12 months for more testing.
isThe project aims to see how the infection affects the development of the immune system and, follow-up studies will reveal how Covid-19 will affect the immune system of their future children.
COVID-19 spreads faster and more widely throughout U.S. households than previously reported, according to new preliminary research from a multicenter study led by Vanderbilt University Medical Center researchers and published in MMWR, a weekly report from the Centers for Disease Control and Prevention (CDC).
The study, led by Carlos G. Grijalva, MD, MPH, associate professor of Health Policy, and H. Keipp Talbot, MD, MPH, associate professor of Medicine, found that 51% of others living in the home with someone who was positive for COVID-19 also became infected.
For Black LGBQ+ Americans, Intersectional Experiences Can Hurt -- Or Help, YSPH Study FindsUsing a new method for quantifying intersectional experiences, a new Yale School of Public Health study finds that Black LGBQ+ Americans tend to feel better about themselves after encountering events that affirm their identity.
One in 4,000 people is born without a corpus callosum, a brain structure consisting of neural fibres that are used to transfer information from one hemisphere to the other. A quarter of these individuals do not have any symptoms, while the remainder either have low intelligence quotients or suffer from severe cognitive disorders.
Like a specter, the question looms: How risky is trick-or-treating with SARS-Cov-2, the virus that causes COVID-19, in the air -- and possibly on the candy?
In a study published October 30, 2020 in the journal mSystems, researchers at University of California San Diego School of Medicine and San Diego State University analyzed the viral load on Halloween candy handled by patients with COVID-19.
Washington, DC - October 30, 2020 - New research shows that COVID-19 exposure risk from contaminated candy could be successfully mitigated both by washing hands and washing candy using a simple at-home method. A team of researchers published this work today in mSystems, an open-access journal of the American Society for Microbiology.
The uncertainty and confusion caused by the COVID-19 pandemic is being "widely exploited by terror groups for spinning a plethora of sinister schemes", which could lead to a new tide of violence against people and governments.
This is the claim of a new international study published in the peer-reviewed Global Security: Health, Science and Policy, which analysed terrorist activity and trends across the globe since the pandemic began.
Currently, approximately 1.6 million Virginians live in primary care shortage areas and 2.2 million in mental health care shortage areas (Kaiser Family Foundation, 2019), yet only three percent of Virginia's high school career and technical education courses are in the health sciences. As the Commonwealth's population grows and ages and demand for care rises, finding effective models for expanding the pipeline of certified health workers is increasingly urgent.
A study involving more than 5,000 COVID-19 patients in Houston finds that the virus that causes the disease is accumulating genetic mutations, one of which may have made it more contagious. According to the paper published in the peer-reviewed journal mBIO, that mutation, called D614G, is located in the spike protein that pries open our cells for viral entry. It's the largest peer-reviewed study of SARS-CoV-2 genome sequences in one metropolitan region of the U.S. to date.
In ecosystems around the globe, the danger of being a common or widespread species is the tendency to be overlooked by conservation efforts that prioritize rarity.
In forests, the most common species can be essential to ecosystem structure and function, which crumble with the decline of these pivotal trees, known collectively as foundation species.
DES PLAINES, IL -- Mobile smartphone technology can accelerate first responder dispatch and may be instrumental to improving out of hospital cardiac arrest (OCHA) survival. That is the conclusion of a study published in the October 2020 issue of Academic Emergency Medicine (AEM), a journal of the Society for Academic Emergency Medicine (SAEM).
