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
Chickens are a blessing for humanity -- from the eggs they deliver to our breakfast table to the main course they become at dinner. Now, there’s another reason to love these versatile birds. Scientists at the University of Virginia say they may teach us how to restore lost hearing in humans.
The scent of Cilantro may go fine with dinner, but not if it’s from a stinkbug that fell into your enchiladas. The invasive pests are now in 41 states, the district of Columbia and Canada and several countries in Europe.
They destroy crops and frustrate humans, with whom they share a penchant for sheltering indoors in cold weather. Now scientists at Virginia Tech have come up with stinkbug trap you can make yourself for a couple of bucks-- that works.
No matter how good a housekeeper you are, it’s not easy to keep stinkbugs from ruining your image.
Some Virginia students, along with First Lady Dorothy McAulifee, got a first-hand look at the State Department of General Services’ secure laboratory. It was part of National Laboratory Week and the experience of seeing DNA and bacteria, is offered to only a few.
