Today I saw a bunch of sensationalist headlines saying things like “Beware! Using your cell phone could lead to brain cancer” and “Risk of brain cancer can triple after 25 years of cellphone use, study finds.” Knowing that scientific reporting can be notoriously overblown, I wanted to dig into this new study to see what it actually said. And guess what? It’s not nearly as conclusive as these headlines would lead you to believe.
How much oxygen does the brain need to stay “conscious”?
An adults brain requires around 20% of the body’s oxygen.
How much blood is needed by the brain?
Approximately 20% of the blood flowing from the heart is pumped to the brain. The brain needs constant blood flow in order to keep up with the heavy metabolic demands of the neurons.
“No man is an island,” John Donne famously wrote. In recent years, neuroscientists have caught up with the wisdom of the 17th century poet in recognizing how important–in fact, essential–it is for us to stay connected and engaged with other people. Read More
How do we learn to read? It isn’t as simple as you might think. In a recent article, Sabra Gelfond, Speech-Language Pathologist and Executive Director of the National Speech / Language Therapy Center, compared the way we learn to read to the way a house is built.

Try these three tips to help you become more focused and productive:
1. Do creative work first.
Typically, we do mindless work first and build up to the toughest tasks. That drains your energy and lowers your focus. “An hour into doing your work, you’ve got a lot less capacity than (at the beginning),” Rock says. “Every decision we make tires the brain.”
In order to focus effectively, reverse the order. Check off the tasks that require creativity or concentration first thing in the morning, and then move on to easier work, like deleting emails or scheduling meetings, later in the day.
