    A new study tracked what happens in the brains of rats in real time in the brain when presented with glucose, a type of sugar, labeled with a tracer. The tracer allowed the researchers to measure this new sugar in the brain.

  • Study links adoption of electric vehicles with less air pollution and improved health
    am 2. Februar 2023 um 20:35

    A team of researchers have now begun to document the actual impact of electric vehicle adoption in the first study to use real-world data to link electric cars, air pollution and health. Leveraging publicly available datasets, the researchers analyzed a 'natural experiment' occurring in California as residents in the state rapidly transitioned to electric cars, or light-duty zero emissions vehicles (ZEVs). The team compared data on total ZEV registration, air pollution levels and asthma-related emergency room visits across the state between 2013 to 2019. As ZEV adoption increased within a given zip code, local air pollution levels and emergency room visits dropped.

    Study shows just one quality conversation with a friend during the day makes you happier and less stressed by day's end.

  • Human brain organoids respond to visual stimuli when transplanted into adult rats
    am 2. Februar 2023 um 16:26

    Researchers show that brain organoids -- clumps of lab-grown neurons -- can integrate with rat brains and respond to visual stimulation like flashing lights.

  • Study provides an explanation and potential solution for severe graft-versus-host disease
    am 2. Februar 2023 um 16:26

    Researchers found that alterations in the gut microbiome that are linked to graft-versus-host disease severity are connected to an increase in oxygen levels in the intestine that follows immune-mediated intestinal damage. Pharmacologically reducing intestinal oxygen levels alleviated the microbial imbalance and reduced the severity of the condition in animal models.
