The spread of Covid-19 pandemic has been unprecedented considering the speed and severity with which it has affected most of the countries in the world. Viewing the magnitude and urgency required in handling the remedial measures, Dr. Allam proposes that we need a scoring system to help us classify the suspected patients in order to determine who would require a follow-up, home isolation, quarantine or further investigations.
Aqueous zinc-based batteries (ZBBs) are widely used for portable and grid-scale applications due to their high safety, low cost and high energy density.
However, the inhomogeneous zinc deposition on anode during charging and the zinc dendrite formation decrease the cycling stability of ZBBs. Moreover, the traditional aqueous electrolytes are not capable of working at low temperature due to the suddenly dropped ionic conductivities, limiting the applicable temperature range of aqueous ZBBs.
Tsukuba, Japan - Cardiovascular disease is the leading cause of death in humans. Worldwide, as the population ages, the burden of treating heart failure is increasing; opportunities for heart transplantation cannot keep pace. As adult cardiomyocytes (heart muscle cells) are terminally differentiated and do not proliferate, regeneration may be the answer. Support cells like fibroblasts can be directly reprogrammed in vitro, but these induced cardiomyocytes (iCMs) are less mature than those in vivo.
August 31, 2020-- A new research letter published online in the Annals of the American Thoracic Society examines whether asthma is a significant risk factor for developing COVID-19 that is severe enough to warrant hospitalization and intubation.
Where you live can increase your risk for experiencing delirium after surgery. So said a study that showed older adults who live in the most disadvantaged neighborhoods are two times more likely to experience delirium after surgery than their counterparts from more affluent communities. These findings by researchers from the Aging Brain Center in the Hinda and Arthur Marcus Institute for Aging Research (Marcus Institute) at Hebrew SeniorLife were published today in the Journal of the American Geriatrics Society.
COLUMBUS, Ohio - People enjoy witnessing extraordinary individuals - from athletes to CEOs - extend long runs of dominance in their fields, a new study suggests. But they aren't as interested in seeing similar streaks of success by teams or groups.
"Everyone wants Usain Bolt to win another gold medal for sprinting. Not so many people want to see the New England Patriots win another Super Bowl," said Jesse Walker, lead author of the study.
Natural wetlands continue to disappear due to city and human development and are being replaced with manmade swales, ponds and canals. This degradation and replacement of natural wetlands suggest that urban areas may be imperative to wetland species, especially when natural conditions are unpredictable. Wetland birds are often seen in and around cities; however, they have been largely ignored in urban wildlife studies. In their historic ranges, wetland birds inhabit dynamic marshes, traveling long distances to locate food.
New research from the University of Virginia School of Medicine is shedding light on the development of the brain's immune defenses - and how those defenses respond to strokes that strike one in 4,000 babies in the first month of life.
"Food systems have the potential to nurture human health and support environmental sustainability; however, they are currently threatening both." This sentence, the opening statement of the EAT-Lancet Report published last year, reflects a growing consensus among global experts on food, nutrition and the environment: Our food system is broken and we need to fix it, fast.
Osaka, Japan - As countries around the world race to develop a vaccine for SARS-CoV-2, the virus responsible for COVID-19, researchers are working to understand exactly how it causes the myriad of symptoms that seem to linger long after active viral infection. In a study published in scientific journal PNAS, researchers led by Osaka University identified an effective treatment for the deadly over-activation of the inflammatory response seen in many severe COVID-19 patients.
About half of the individuals of cowslip (Primula veris) have flowers with a short style, while the other half of individuals produce flowers with a long style. Recent discoveries have suggested that the loss and fragmentation of habitats may shake this optimal balance of morphologically different plants. This, in turn, decreases the reproductive success of plants and jeopardizes their future viability.
Prof. DONG Zhenchao and Prof. HOU Jianguo from University of Science and Technology of China (USTC) of Chinese Academy of Sciences (CAS) improved the spatial resolution from 8 nm to ~8 Å of photoluminescence imaging. It realized sub-molecular resolution with single molecule photofluorescence imaging for the first time.
This study was published in Nature Photonics on August 10.
To reach atomic resolution with light has always been one of the ultimate goals in nano-optics. The advent of scanning near-field optical microscopy (SNOM) kindled hopes for the goal.
SEATTLE (August 27, 2020) - A new study projects that 3.1 billion people will still lack effective health service coverage in 2023, with 968 million of those residing in South Asia. This falls short of the World Health Organization (WHO) goal of 1 billion more people benefiting from universal health coverage (UHC) between 2019 and 2023.
The link between influenza and serious heart conditions just grew stronger.
A CDC study looking at more than 80,000 adult patients hospitalized with flu over eight seasons found that sudden, serious heart complications were common, occurring in 12% of patients, or 1 in 8.
"Previous to our study, there had been suggestions between the link, but our study shows just how common it is," said lead author Eric Chow, an infectious diseases fellow at University of Washington School of Medicine.
The northern quoll, one of Australia's most adorable and endangered native carnivores, appears to be adapted to dramatically different landscapes - which may be key to the species' survival.
University of Queensland PhD candidate Pietro Viacava co-led a study that found similarities between northern quoll skulls across a 5000 kilometre range, which has raised hopes scientists will be able to cross-breed isolated populations.
"Northern quolls are in danger - a lot has been thrown at them," Mr Viacava said.
