COVID-19 vaccination strategies: When is one dose better than two?

Added: 08.11.2021 21:37 | 211 views | 0 comments

While most of the COVID-19 vaccines are designed as a two-dose regimen, some countries have prioritized vaccinating as many people as possible with a single dose before giving out an additional dose. In a new study, researchers illustrate the conditions under which a "prime first" vaccine campaign is most effective at stopping the spread of the COVID-19 virus. The team found the vaccine waning rate to be a critically important factor in the decision.

Simulation illustrates how COVID-19 social distancing creates pedestrian 'traffic jams'

Added: 08.11.2021 21:37 | 176 views | 0 comments

Researchers examine the dynamics of social distancing practices, common defense against the spread of COVID-19, through the lens of particle-based flow simulations. The study models social distance as the distance at which particles, representing pedestrians, repel fellow particles and sheds light on the relationship between social distancing and pedestrian flow dynamics in corridors by illustrating how adherence to social distancing protocols affects two-way pedestrian movement in a shared space.

Targeted interventions to contain pandemics, minimize societal disruption

Added: 08.11.2021 21:37 | 180 views | 0 comments

Nonpharmaceutical interventions, such as isolation, quarantines, and lockdowns, have been implemented in an effort to contain the pandemic, but these are often disruptive and costly. In a new article, researchers identify new and sustainable interventions to contain outbreaks while minimizing the economic and social costs. They built a data-driven mobility model to simulate COVID-19 spreading in Hong Kong, by combining synthetic population, human behavior patterns, and a viral transmission model, and found that by controlling a small percentage of grids, the virus could be largely contained.

Lakeside education campaigns discourage anglers from transporting aquatic hitchhikers between lakes, but new research hows those campaigns are less effective than they could be. According to the study, the key could be tailoring messaging in accordance with anglers' value systems and risk perceptions.

COVID's crushing impact on public health

Added: 08.11.2021 21:37 | 210 views | 0 comments

A new study captures the scope of the COVID-19 pandemic's impact on public health: Many public health workers have been redeployed to COVID-related duties, leaving other critical public health issues with reduced or suspended services. That means investigation of other communicable diseases, food-related illness, public-health surveillance, chronic diseases and other critical services have suffered.

The severe outbreak of COVID-19 in Delhi, India, in 2021 showed not only that the Delta variant of SARS-CoV2 is extremely transmissible but that it can infect individuals previously infected by a different variant of the coronavirus, say scientists.

A new computational analysis suggests that, beyond the initial effect of one infected person arriving and spreading disease to a previously uninfected population, the continuous arrival of fected individuals has a significant influence on the evolution and severity of the local outbreak.

By 2500 Earth could be alien to humans

Added: 08.11.2021 21:37 | 223 views | 0 comments

To fully grasp and plan for climate impacts under any scenario, researchers and policymakers must look well beyond the 2100 benchmark. Unless CO2 emissions drop significantly, global warming by 2500 will make the Amazon barren, the American Midwest tropical, and India too hot to live in, according to a team of international scientists.

The massive columns of smoke generated by a nuclear war would alter the world's climate for years and devastate the ozone layer, endangering both human health and food supplies, new research shows. The international study draws on newly developed computer climate modeling techniques to paint an even grimmer picture of a global nuclear war's aftermath than previous analyses.

During the COVID-19 pandemic, addiction treatment providers rapidly pivoted to providing services via telehealth. New research highlights the potential for telehealth delivery to increase patient engagement by improving access and convenience. However, it also finds limited evidence that telehealth results in better retention or other outcomes relative to in-person treatment.

More than half of the 236 million people who have been diagnosed with COVID-19 worldwide since December 2019 will experience post-COVID symptoms -- more commonly known as 'long COVID' -- up to six months after recovering, according to researchers. The research team said that governments, health care organizations and public health professionals should prepare for the large number of COVID-19 survivors who will need care for a variety of psychological and physical symptoms.

Lack of power grids sealed fate for early electric cars

New research shows that insufficient infrastructure was key in American car manufacturers choosing gasoline cars over electric cars in the early 20th century. If electricity grids had spread just 15 or 20 years earlier, a majority of producers would have likely opted for electric cars, according to the study.
