Understanding New Brain Research Models
Scientists can now grow living human brain tissue in lab dishes and in animals, creating organoids, neural transplants, and chimeras. While these models will help us better understand the brain in health and disease, they also raise thorny ethical questions that will only get thornier in the future.
Neuroimaging: Many Analysts, Differing Results
70 teams processed the same collection of fMRI data – using different software, taking different steps, and setting different thresholds—and came to different conclusions more than half the time. With today’s huge datasets and multiple methods of analysis, it’s critical that researchers describe their methods precisely so others can reproduce their results.
KidTalk: A Natural Experiment in the Time of Covid-19
A new citizen-science project offers parents a virtual scrapbook to record their children’s speech, so researchers can see how their language skills develop in home settings—as well as see how they may be affected by staying at home during the pandemic.
