Wintertime outbreaks of COVID-19 have been largely driven by whether people adhere to control measures such as mask wearing and social distancing, according to a study published Feb. 8 in Nature Communications by Princeton University researchers. Climate and population immunity are playing smaller roles during the current pandemic phase of the virus, the researchers found.
Ancient Amazonian communities fortified valuable land they had spent years making fertile to protect it from conflict, excavations show.
Farmers in Bolivia constructed wooden defences around previously nutrient-poor tropical soils they had enriched over generations to keep them safe during times of social unrest.
Announcing a new article publication for BIO Integration journal. In this review article the authors Yue Li, Zhiyi Chen and Shuping Ge from First Affiliated Hospital of University of South China, Hengyang, China and Tower Health and Drexel University, Philadelphia, PA, USA summarize current state of the art applications of microbubble-cell interactions and sonoporation effects to cellular functions.
LA JOLLA, CA--As new COVID-19 variants begin to throw vaccine efficacy in question, two leading scientists are calling for health agencies to invest in the development of vaccines that would be broadly effective against many different variants and strains of potential pandemic viruses.
Photoplethysmography (PPG) is a simple optical technique used to detect volumetric changes in peripheral blood circulation. It's used in smart watches, for example, to monitor pulse and heart rate, but PPG biosensors are also found in millions of smartphones, but without any current clinical applications.

Rapid, Living Practice Points from ACP: Update on remdesivir use for hospitalized COVID-19 patients
Headlines like "Black Friday Shoppers Trampled in New York" and popular television shows such as "Extreme Couponing" remind us how crazy consumers can get about retail sales promotions. This enthusiasm for getting bargains has been termed "deal proneness."
While deforestation levels have decreased significantly since the turn of the 21st century, the United Nations (UN) estimates that 10 million hectares of trees have been felled in each of the last five years.
Aside from their vital role in absorbing CO2 from the air, forests play an integral part in maintaining the delicate ecosystems that cover our planet.
Commuters now have yet another reason to avoid packing themselves into subway stations. New York City's transit system exposes riders to more inhaled pollutants than any other metropolitan subway system in the Northeastern United States, a new study finds. Yet even its "cleaner" neighbors struggle with enough toxins to give health-conscious travelers pause.
As abundant and widespread bees, it is common to see both bumble bees and honey bees foraging on the same flower species during the summer, whether in Britain or many other countries.
Yet researchers at the Laboratory of Apiculture and Social Insects (LASI) at the University of Sussex, show that these two different bees dominate on different flower species and have found out why.
Scientists studying forest dwelling butterflies in Central and South America have discovered that changes in the way animals perceive and process information from their environment can support the emergence of new species. The study led by the University of Bristol, and published today [9 February] in the Proceedings of the National Academy of Sciences (PNAS), has implications for how new species might evolve and the underappreciated role of changes in the brain.
BOSTON -- Hospitals across the United States have gone to great lengths to implement infection control measures to prevent transmission of SARS-CoV-2. And yet, as the pandemic has unfolded, many health care settings have experienced clusters of cases, with the virus spreading among patients, staff or both. Some clusters have been easily traced back to break rooms and shared meals. But other clusters have been challenging to trace and contain.
DALLAS - Feb. 8, 2021 - World health experts have long suspected that the incidence of COVID-19 has been higher than reported. Now, a machine-learning algorithm developed at UT Southwestern estimates that the number of COVID-19 cases in the U.S. since the pandemic began is nearly three times that of confirmed cases.
One of the dozens of unusual symptoms that have emerged in COVID-19 patients is a condition that's informally called "COVID brain" or "brain fog." It's characterized by confusion, headaches, and loss of short-term memory. In severe cases, it can lead to psychosis and even seizures. It usually emerges weeks after someone first becomes sick with COVID-19.
A new study in Frontiers in Communication has demonstrated the powerful impact that subtle messaging and cues, or 'nudges', can provide on encouraging people to show socially desirable behaviors.
