Hair products often contain ingredients that easily evaporate, so users may inhale some of these chemicals, potentially posing health repercussions. Now, researchers have studied emissions of these volatile organic compounds (VOCs), including siloxanes, which shine and smooth hair. The scientists report that using these hair care products can change indoor air composition quickly, and common heat styling techniques -- straightening and curling -- increase VOC levels even more.

Hospital MRI scanners, using 3 Tesla magnets, provide poor spatial resolution in brain imaging. More recent 7T MRIs are better but used mainly in the rare research lab. Scientists have now supercharged the standard 7T scanner to improve the resolution by nearly a factor of 10 -- a 50-times improvement over standard 3T MRIs. The NexGen 7T can track signals through the brain and perhaps tie functional changes to brain maladies.

An innovative stem cell-based treatment for Type 1 diabetes can meaningfully regulate blood glucose levels and reduce dependence on daily insulin injections, according to new clinical trial results. The therapy aims to replace the insulin-producing beta cells that people with Type 1 diabetes lack. Dubbed VC-02, the small medical implant contains millions of lab-grown pancreatic islet cells, including beta cells, that originate from a line of pluripotent stem cells.
