Growing blood stem cells in the lab to save lives

Researchers developed a new cell culture system for expanding human hematopoietic stem cells (HSCs) in the laboratory. The new system’s culture medium is free of cytokines and albumin, once believed to be essential components for HSC growth. Using vari…

New method predicts extreme events more accurately

A new study has used global storm-resolving simulations and machine learning to create an algorithm that can deal separately with two different scales of cloud organization: those resolved by a climate model, and those that cannot be resolved as they a…

Microplastics are harming gut health

Scientists have found evidence that microplastics in the digestive tract of seabirds altered the microbiome of the gut — increasing the presence of pathogens and antibiotic-resistant microbes, while decreasing the beneficial bacteria found in the inte…
