The recent trend toward e-cigarettes as a way to avoid the dangers of smoking may not be as safe as previously thought.  Scientists at Virginia Tech now say nicotine; even in non-smoke-able forms can,  cause cancer.

There’s now an entire industry based on smoking cessation aids, such as nicotine gums, lozenges and the newest delivery devices, e- cigarettes.  But according to Geneticist, Skip Garner, nicotine itself, once thought to be merely addictive is also carcinogenic.

The elements known as ‘rare earths,’ are a relatively new addition to the periodic table. And they have changed the world, ushering in the new age of technology because of their unique properties. They allow us to make smaller and more efficient devices; everything from smart phones to wind turbines.

Metals known as ‘rare earth elements” are in growing demand worldwide.  They’re vital for many of the high tech devices we all use.  China has been the major source for rare earth minerals, but recently cut its exports. This has geologists in the U.S. searching for domestic deposits. 


If the term ‘rare earths’ is not familiar to you, the high tech devices that depend on them are. From the ear buds for your cell phone, to advanced medical devices like MRIs, and new technologies such as wind turbines, magnetic refrigeration and electric cars

People who spend much time in an American hospital may begin to feel like they’re surrounded by vampires. 

Blood testing is a key part of modern medicine, and patients may be subject to dozens of needle sticks over the course of a week.  Now, a device developed by students at the University of Virginia could change all that. 

Just as the season for getting outdoors gets into full swing, so does a noxious weed that can take the fun out of summer outings.

Poison Ivy, which causes an itchy rash in eighty per cent of people who come in contact with it, is on the rise in the US, fueled by rising C-O2 levels.

But scientists at Virginia Tech have found that the weed contains the seeds of its own destruction –a kind of poison pill could be used to control the plant in the landscape.
