'Ensemble' modeling could lead to better flu forecasts, study finds

By combining data from a variety of non-traditional sources, a research team led by computational epidemiologists at Boston Children's Hospital has developed predictive models of flu-like activity that provide robust real-time estimates (aka "now-casts") of flu activity and accurate forecasts of...

Vitamin D deficiency may limit immune recovery in HIV-positive adults

Athens, Ga. - A University of Georgia researcher has found that low levels of vitamin D may limit the effectiveness of HIV treatment in adults. Read More

Microbiomes could hold keys to improving life as we know it

A consortium of 48 scientists from 50 institutions in the United States - including Pamela Silver, Ph.D., a Core Faculty member at the Wyss Institute for Biologically Inspired Engineering at Harvard University - are calling for a Unified Microbiome Initiative that would span national cross-insti...

Wibbly-wobbly-timey-wimey

A Time Lord needs his TARDIS to embark on fantastic discoveries. These LB agar plates contain a colorless reagent called X-gal, which is the sugar galactose linked to a dark blue dye. Some microbes can synthesize an enzyme (β-galactosidase) that snips the X-gal in two, releasing the blue color a... Read More

However, researchers point out that if the SARS-like virus did jump, it is still unclear whether it could spread from h... Read More

MGH team broadens utility of more compact CRISPR-Cas9 by increasing its targeting range

A team of Massachusetts General Hospital (MGH) investigators has shown that a method they developed to improve the usefulness and precision of the most common form of the gene-editing tools CRISPR-Cas9 RNA-guided nucleases can be applied to Cas9 enzymes from other bacterial sources. In a paper r... Read More
