Attack on 2 fronts leads ocean bacteria to require carbon boost
The types of ocean bacteria known to absorb carbon dioxide from the air require more energy – in the form of carbon – and other resources when they’re simultaneously infected by viruses and face attack from nearby predators, new research has found.
Current vaccine approach not enough to eradicate measles
Current vaccination strategies are unlikely to eliminate measles, according to a new study led by faculty at the University of Georgia. The paper, which published today in The Lancet Global Health, explores the feasibility of eliminating measles and rubella using predominant vaccination strategies in 93 countries with the highest disease burden.

A New Approach Produces a 90-Fold Increase in Known Viral Taxa
Viruses play an essential role in regulating microbiomes. However, the use of metagenomics and metatranscriptomics have produced taxonomies of only a tiny proportion of the world’s viruses. In this study, researchers used a novel algorithm to compare and incorporate 715,672 metagenome viruses from environmental samples around the world. This expands the viral taxa available to researchers from about 8,000 to 723,672. The scientists then used the data to examine samples from two Populus tree genotypes.

Houston Methodist expert notes COVID-19 precautions lead to historic drop in flu cases
A silver lining is emerging amid the COVID-19 pandemic. Influenza numbers are way down – 98 percent down, according to the CDC. Locally, during flu season last year, Houston Methodist’s system of eight hospitals saw 250 to 450 flu cases per week. This year the hospital system has seen only 2 to 5 flu cases per week so far. The numbers tell a striking story. Handwashing, masking and social distancing work.

What’s That Growing on Your Face Mask?
Many people reuse masks and other face coverings many times without sanitizing them. That is likely because current sanitization methods can be cumbersome. A new device using a hanging rack and UV-C light can sterilize up to six masks and other items simultaneously and quickly, killing bacteria, yeasts, mold spores, and viruses. This device has shown its efficacy against pathogens including the highly-contagious E-coli, which was eradicated in about one minute.

With thousands of new cases logged daily and a vaccine to fight COVID-19 still in development, UCLA Health infectious disease experts are encouraging people to continue to wear masks as the best method of protecting against virus transmission.
Ocean Algae Get “Coup de Grace” from Viruses
Scientists have long believed that ocean viruses always quickly kill algae, but Rutgers-led research shows they live in harmony with algae and viruses provide a “coup de grace” only when blooms of algae are already stressed and dying. The study, published in the journal Nature Communications, will likely change how scientists view viral infections of algae, also known as phytoplankton – especially the impact of viruses on ecosystem processes like algal bloom formation (and decline) and the cycling of carbon and other chemicals on Earth.
