How safe are our cell phones really? The evidence over the years has remained unclear, with the World Health Organization designating cell…

New lab technique improves how we study the microbiome Scientists started out wanting to study how Vitamin A affects our gut flora. They ended up coming up with a new way to count bacteria by encasing them in tiny droplets and tagging each one with DNA “barcodes”, detecting more detail than older techniques could.

Nature has been able to filter out CO2 from our air for millions of years. So how might a battery prove to be our own artificial tree?…

This new tiny biomedical device makes diagnosing cancer types easier A team of scientists has made valves which can operate on tiny channels of fluid the width of 3 human hairs. It can deliver colored stains to tissue samples accurately, so that scientists can view cancer cells under the microscope more easily.
