Global Virus Network experts: New flu strain underscores urgent need for vigilance, vaccination, and investment in virus science

Global Virus Network experts warn of a more intense flu season worldwide due to the emergence of the new H3N2 subclade K variant. The strain is spreading rapidly and may contribute to earlier and more widespread influenza activity across multiple regions, underscoring the importance of continued investment in virus science.

Soil carbon decomposition varies vastly, holding implications for climate models

A new study found that the rate of organic carbon decomposition in soil samples collected across the US differed by up to tenfold, with factors like fungi and iron levels strongly associated with variation. This could improve the accuracy of soil carbon feedback estimates in climate models, leading to more refined projections.

Scientists get a first look at the innermost region of a white dwarf system

Researchers used NASA's IXPE telescope to study the innermost region of an intermediate polar, revealing a surprisingly high degree of X-ray polarization and an unexpected direction of polarization. The team found that X-rays were emitted from a column of white-hot material pulled in by the white dwarf's strong magnetic field.

Everyday routines in early infancy may shape later obesity risk, study finds

Researchers found that everyday routines in early infancy can shape later obesity risk. A new study from Penn State suggests that a handful of routines around feeding, sleep and play during the first two months of an infant's life can be linked to higher weight just a few months later. The EHL tool helps pediatricians identify specific...
