Scientists 'inject' information into monkeys' brains In an experiment with science fiction implications, two neuroscientists say they have managed to introduce information directly into the premotor cortex of monkeys. PHOTO CREDIT: Christoph Hitz/NYT When you drive towards an intersection, the sight of the light turning red will make you step on the brake. This action happens due to a chain of events inside your head. Your eyes relay signals to the visual centres in the back of your brain. After those signals get processed, they travel along a pathway to another region, the premotor cortex, where the brain plans movements. Signalling the brain Now, imagine that you had a device implanted in your brain that could shortcut the pathway and 'inject' information straight into your premotor cortex. That may sound like an outtake from The Matrix. But now two neuroscientists at the University of Rochester, USA say they have managed to introduce information directly into...

Children and books !!!😊😊😊 Children are natural scientists, born wanting to explore the world around them. This book provides a range of activities most appropriate for children ages 10 to 15 years old, with some parental help and supervision, aimed at igniting kids’ interest in different aspects of science. The experiments presented  focus on various explorations of microbiology, entomology, and animal behavior, as well as some simple chemistry, engineering, and physics experiments. Each section gives detailed instructions and approximate times to completion as well as a walk-through of the actual project as performed by real kids. I found it especially realistic when experiments failed. Anyone who has worked in a lab will appreciate how the author walks readers through the scientific method and provides suggestions for further experiments and troubleshooting for the more problematic investigations. The book ends with a section specifically aimed at preparing for a science fai...
