Lateral flow testing should not be used as a green light for activities

A study published in PLOS Biology suggests that Lateral Flow Devices (LFDs) are more effective at detecting higher quantities of SARS-CoV-2 viral RNA, but struggle to identify infections in individuals with lower viral loads. The research highlights the need for frequent testing, particularly in early or late stages of infection.

The Arctic's greening, but it won't save us

New research suggests that the Arctic's increasing plant biomass is not enough to absorb large amounts of carbon dioxide, as most of it is released through fires and timber harvests. The study estimates that only 430 million metric tons of biomass have accumulated over 31 years, with much of it being lost due to wildfires.

Digital mental health interventions for young people are perceived promising, but are they effective

Computerized cognitive behavioral therapy was found effective for anxiety and depression in adolescents and young people. However, the effectiveness of other digital interventions remains inconclusive. Engagement with a health professional or peer can strengthen the effectiveness of these interventions.

Alzheimer's disease is composed of four distinct subtypes

Researchers have identified four distinct patterns of tau pathology in Alzheimer's disease, each leading to unique symptoms and prognoses. These subtypes include variant one, which primarily affects memory, and variants two, three, and four, which impact executive functions, visuospatial processing, and language ability, respectively.

Many Hispanics died of COVID-19 because of work exposure

A new study by Ohio State University researchers suggests that Hispanic Americans are disproportionately affected by COVID-19 due to workplace exposure. The analysis of federal data showed that Hispanics of working age have died of COVID-19 at a higher rate than whites, with excess cases and deaths also highest among this group.

More than 25% of infants not getting common childhood vaccinations, study finds

A recent study from the University of Virginia Health System found that more than a quarter of American infants in 2018 had not received all recommended childhood vaccines. Disparities were observed among African-American infants, low-income families, and those with lower education levels. The researchers warn that these gaps can lead ...
