Taking their vitamins

New research from North Carolina State University and the University of Copenhagen finds that most bacterioplankton are B1 auxotrophs, meaning they have to glean the vitamin or pieces of it from their environment. The study also reveals fluctuations in genes responsible for making and/or using environmental B1 and precursors over time.

Genomic analysis offers insight into 2018 Nigeria Lassa fever outbreak

A genomic analysis of Lassa virus genomes from patients in Nigeria found that the surge in cases in 2018 was not driven by a single dominant virus strain. The study suggests that human-to-human transmission may be rare, with evidence pointing to multiple independent zoonotic transmissions through contact with rodent feces or urine.

A stabilizing influence enables lithium-sulfur battery evolution

Researchers at Drexel University have developed a stable cathode material that can hold polysulfides in place, maintaining energy density while reducing weight and production time. The new approach uses titanium monoxide nanofibers to immobilize polysulfides, enabling Li-S batteries to achieve superior performance through hundreds of c...

Can forests save us from climate change?

A new study published in Nature found that sustainable forest management can only provide modest, local benefits rather than a significant impact on the global climate. Forests themselves will need to be adapted to climate change to sustain their ecological and social services.

When it comes to smartphone lifespan, brand name matters more than hardware

A new study by Yale researchers found that brand cache plays a significant role in extending smartphone lifespans, with iPhones lasting up to 67 months compared to Samsung phones' 54.5 months. The study analyzed over 500,000 secondhand phone listings on eBay and found that Apple's brand reputation contributes to its longer lifespan.
