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.
KEY STUDY FINDINGS INCLUDE:
2.9% of U.S. adults report a current peanut allergy.
About one in six adults with a peanut allergy developed it after age 18.
Approximately one in five adults with peanut allergy report visiting the emergency department for food allergy treatment each year.
Patients who developed their peanut allergy during adulthood are less likely to report having an epinephrine auto-injector prescription than those who developed their peanut allergy during childhood, despite similar frequencies of severe reactions among both groups.
Researchers at Baylor College of Medicine and other institutions have identified a novel strategy that can eliminate bacteria in a specific location before they cause an infection. The strategy uses a phage, a virus that infects and destroys bacteria, that can specifically locate in the same place the bacteria live in the gastrointestinal tract. The proximity between phage and bacteria facilitates the phage's attack and subsequent elimination of the bacteria.
The world is changing rapidly and in order to serve the human population dealing with those changes, American universities need to change, too. In fact, their role is to model the resiliency that all institutions need to embrace, according to Arizona State University President Michael M. Crow.
