Looking for a good night’s sleep? You’re not alone. More than a third of adults aren’t getting the recommended seven hours of sleep (never mind the ideal eight), according to a report from the Centers for Disease Control and Prevention (CDC) in 2014.

As cold weather grips a majority of the country, it may be easy to think that all life is dead when the ground is frozen, at least until spring breathes new life into the plant systems and surrounding environments.

The signs have been there all along when it comes to using mechanical stimulation to stimulate regeneration and growth of tissue by simply pulling or pushing on cells. Think of a pregnant woman whose womb expands as the baby grows or a doctor telling a patient to lift weights to fight off osteoporosis by promoting bone growth.

These days it is hard not hear about the latest massive wildfires that have ravaged Southern California. The Thomas fire, in particular, has now become the largest of its kind in the state’s history after destroying more than 280,000 acres and thousands of homes and buildings.

While a warming climate and the record drought that the state suffered from 2012 to 2015 certainly appear to be major culprits for the rash of monstrous blazes, the human/urban component may shoulder the biggest blame, according to new research.

Many of us have our cellphones within an arm’s reach at all times. It’s either in a pocket or a purse or maybe just a few inches from our face on a daily basis. Given how tethered we are to these devices, scientists have been studying any possible health maladies that could result from cellphone exposure — radiation amounts, in particular.

Today, as the Trump administration continues to bolster the fossil fuel industry — loosening regulations and giving large tax breaks to fossil fuel companies — environmentalist Bill McKibben says that it would be wise to follow the dollar to see where the future of energy is headed, globally. 

“Right now, of course, politics is making it difficult to deal with climate change in DC, but it's not stopping cold all the work that's going on,” says McKibben, co-founder of 350.org.
