Sleep-Walking Neurons: Brain’s GPS Never Stops Working – Even During Sleep

View | Comment

Researchers at NYU Langone Medical Center have found that navigational brain cells that help sense direction are as electrically active during deep sleep as they are during wake tim. Such information could be useful in treating navigational problems associated with Alzheimer’s disease and other neurological disorders.

Two UW-Madison graduate students are working to introduce highly productive kits for farming mealworms to regions such as sub-Saharan Africa where eating insects is already culturally palatable. They are just practicing what they are beginning to preach: insects, and mealworms in particular, are an overlooked, healthful, economically viable and sustainable source of nutrition for people.

The organisms commonly known as blue-green algae have proliferated much more rapidly than other algae in lakes across North America and Europe over the past two centuries – and in many cases the rate of increase has sharply accelerated since the mid-20th century, according to an international team of researchers.

First Direct Observation of Carbon Dioxide’s Increasing Greenhouse Effect at the Earth’s Surface

View | Comment

Scientists have observed an increase in carbon dioxide’s greenhouse effect at the Earth’s surface for the first time. They measured atmospheric carbon dioxide’s increasing capacity to absorb thermal radiation emitted from the Earth’s surface over an eleven-year period at two locations in North America. They attributed this upward trend to rising CO2 levels from fossil fuel emissions.

How Sensor-Packed Smartphones Can Read Your Mood, Guard Your Data — and Wreak Havoc in the Wrong Hands

View | Comment

Smartphones have replaced nearly every conceivable gadget, but UAB computer scientists are teaching them some new tricks. The researchers are adapting accelerometers, GPS chips, gyroscopes and other sensors to make phones that can read a user's mood, eliminate passwords, protect financial transactions and more.
