How much spring and summer affect the COVID-19 pandemic may depend not only on the effectiveness of social distancing measures, but also on the environment inside our buildings, according to a review of Yale scientists of their own work and that of colleagues on how respiratory viruses are transmitted.
Nearly a millennium and a half ago, red light streaked the night sky over Japan. Witnesses compared it to the tail of a pheasant -- it appeared as a fan of beautiful red feathers stretched across the sky. Since the event, scientists have studied the witness accounts written in the year 620 A.D. and speculated about what the cosmic phenomenon could have actually been. Now, researchers from The Graduate University for Advanced Studies may have found the answer.
They published their results on March 31, 2020 in the Sokendai Review of Culture and Social Studies.
COLUMBUS, Ohio - There's a price to pay when you get your news and political information from the same place you find funny memes and cat pictures, new research suggests.
The study found that people viewing a blend of news and entertainment on a social media site tended to pay less attention to the source of content they consumed - meaning they could easily mistake satire or fiction for real news.
From health care to education to media, social distancing across the globe due to coronavirus (COVID-19) has created the need to conduct business "virtually" using Skype, web conferencing, FaceTime and any other means available. With this expansive use of mobile and video devices, now more than ever, it is important to understand how the use of these technologies may impact communication. But are all forms of online communication alike?
Human stem cells have been regarded as one of the promising cell sources for cardiac regeneration therapy. But their clinical use is hampered due to the poor performance after transplantation into failing hearts. Recently a stem cell biologist from City University of Hong Kong (CityU), together with his collaborators, has developed a novel strategy, called in vivo priming, to "train" the stem cells to stay strong after implantation to the damaged heart via the 3D-printed bandage-like patch.
March 26, 2020 -- Columbia Mailman School of Public Health's Dr. John W. Rowe, Professor of Health Policy and Aging, is a member of a WHO Expert Panel on Care of the Elderly which just released the attached guidance for prevention and management of COVID-19 among elderly in long term care facilities.
UNIVERSITY PARK, Pa. -- In uncertain times, supporting your friends and family can help them make it through. But your comforting words can have different effects based on how you phrase them, according to new Penn State research.
The researchers studied how people responded to a variety of different messages offering emotional support. They found that messages that validated a person's feelings were more effective and helpful than ones that were critical or diminished emotions.
We've all seen the documentaries that feature scenes of mass migrations on land. Those videos are pretty impressive showing all sorts of animals - birds, mammals and other creatures - on the move. What wasn't known was to what extent this was taking place in the deepest parts of our oceans.
That was until now.
Scientists have, for the first time, documented seasonal migrations of fish across the seafloor in deep-sea fish, revealing an important insight that will further scientific understanding of the nature of our planet.
When it comes to finding a mate, male guppies rely on their brothers to ward off the competition.
In a new study published by a Florida State University team, researchers found that male Trinidadian guppies observe a form of nepotism when it comes to pursuing the opposite sex. These tiny tropical fish often help their brothers in the mating process by darting in front of other males to block access to a female.
Facebook users flipping through their feeds in the fall of 2016 faced a minefield of targeted advertisements pitting blacks against police, southern whites against immigrants, gun owners against Obama supporters and the LGBTQ community against the conservative right.
Placed by distant Russian trolls, they didn't aim to prop up one candidate or cause, but to turn Americans against one another.
The ads were cheaply made and full of threatening, vulgar language.
Photonic Integrated Circuits (PICs), particularly those built from silicon, are being increasingly seen as the future of ultra-high-speed communications. However, despite nearly 30 years of research there is still no low-cost route to reliably integrating lasers or gain regions onto these devices. Current approaches, such as bonding III-V lasers directly to chips, or growing III-V structures directly onto silicon have been used but still don't meet all the requirements of industry.
Nobody likes to make mistakes, because they usually cause trouble. But what if a mistake sometimes makes things better than before? If so, it may make sense not to aim for perfection. Just like we navigate from one language to another through translation, cells routinely translate from a primary language (encoded by sequences of DNA) into a second language (encoded by sequences of proteins). Bacteria do not always make a protein whose sequence is exactly as specified in the gene; invariably, there are a number of mistakes.
Autism Spectrum Disorder (ASD) is a set of conditions that affect a baby, toddler or preschooler's mental development. The signs can come on as early as 6 months, but usually, in India, diagnosis happens around 3-5 years. ASD is diagnosed as a problem in social communication- language, non-verbal signs of social interaction, and compulsive interests or activities that the child insists on doing to the exclusion of everything else. Mental retardation, epilepsy, and attention deficit issues may also accompany ASD.
GAINESVILLE, Fla. --- Smaug, the deadly dragon in J.R.R Tolkien's "The Hobbit," has a few living relatives. With dense, alligator-like armor, these small, real-life dragon lizards are rock-crevice recluses mostly confined to mountaintops in southern Africa.
Early mortality of myocardial infarction (MI), one of fatal diseases, is about 30%. So, it is critical to have immediate and proactive treatment to prevent a heart attack. Contributing to developing an efficient treatment of this fatal disease, a research team from South Korea recently proposed an effective stem cell treatment system for myocardial infarction, using harmless protein from mussel and stem cells.
