New clinical practice guideline on community acquired pneumonia
In its latest clinical practice guideline on community-acquired pneumonia the American Thoracic Society's guidelines panel addresses the use of nucleic acid-based testing for non-influenza viral pathogens. The guideline was published online in the May 1 issue of the American Journal of Respiratory and Critical Care Medicine. An explainer video may be viewed here.

New study traces back the progenitor genomes causing COVID-19 and geospatial spread
Sudhir Kumar's team reconstructed the genome of the SARS-CoV-2 progenitor and its early pedigree from a dataset of coronavirus genomes. They found the SARS-CoV-2 progenitor was already circulating with an earlier timeline, at least 6 to 8 weeks prior to the first genome sequenced in China. They have also developed an intuitive mutational fingerprint and Greek symbol classification categorization system of the major strains, sub-strains and variants infecting an individual or colonizing a global region.

Pandemic worsened older adults' mental health & sleep; others show long-term resilience
Nearly one in five older adults say their mental health has gotten worse since the pandemic began in March 2020, and an equal percentage say their sleep has suffered in that time too. More than one in four say they're more anxious or worried than before the COVID-19 era, according to a new poll of people age 50 to 80. But the poll also reveals hopeful signs that many older adults are showing long-term resilience.

Air pollution linked to high blood pressure in children; other studies address air quality and the heart
A meta-analysis of 14 air pollution studies from around the world found that exposure to high levels of air pollutants during childhood increases the likelihood of high blood pressure in children and adolescents, and the risk of hypertension later in life.A special publication on air pollution features several studies focused on the relationship between ambient air pollution with cardiovascular risk factors such as hypertension.

Chemical 'nose' sniffs critical differences in DNA structures
Small changes in the structure of DNA have been implicated in breast cancer and other diseases, but they've been extremely difficult to detect -- until now. Using what they describe as a "chemical nose," UC Riverside chemists are able to "smell" when bits of DNA are folded in unusual ways.

Climate action potential in waste incineration plants
The climate action potential of carbon capture during the processing of biomass feedstock is considerable, ETH Zurich researchers have calculated. If this potential is to be fully exploited in practice, however, there are challenges to overcome.

Microplastics found in Europe's largest ice cap
In a recent article in Sustainability, scientists from Reykjavik University (RU), the University of Gothenburg, and the Icelandic Meteorological Office describe their finding of microplastic in a remote and pristine area of Vatnajokull glacier in Iceland, Europe's largest ice cap. Microplastics may affect the melting and rheological behaviour of glaciers, thus influencing the future meltwater contribution to the oceans and rising sea levels.

Algorithms improve how we protect our data
Daegu Gyeongbuk Institute of Science and Technology (DGIST) scientists in Korea have developed algorithms that more efficiently measure how difficult it would be for an attacker to guess secret keys for cryptographic systems. The approach they used was described in the journal IEEE Transactions on Information Forensics and Security and could reduce the computational complexity needed to validate encryption security.
