Environmental Science

The environment is truly a thing of beauty and should be protected whenever possible. What can we do to save the environment, and what new technology is available to help us?

To say geologic time moves at a snail's pace is an insult to snails. Our planet's continents are always in flux: Could a new ocean grow amid those incredibly slow changes?

We argue that living well requires wine and cheese, but what does living at all require? You might be surprised to find out that there's no single definition.

They bring herds of identical friends, they eat all the food and they just won't leave the party. How can we get rid of these uninvited guests in Earth's ecoystems?

Farming technologies have allowed the world to be fed, even though most people no longer farm. Only 2 percent of Americans are farmers, versus 90 percent in the 1700s. Which tools and technologies have had the most impact on farming and why?

The oceans are rising, and they're threatening to take down some of the world's brightest cultural gems. Here are 10 of the most notable spots potentially endangered by climate change.

"It's been so cold this winter — so much for global warming." Ever heard anyone say that? We explain why cold weather — and nine other things – don't disprove global warming.

We live in an age when DIY has taken on exciting, nerve-wracking connotations. Add in some knowledge and some money from crowdfunding sites like Kickstarter, and you have a recipe for a transformed world. Will glow-in-the-dark plants be a part of it?

You likely heard that paleontologists uncovered a cache of dinosaur embryos, bone fragments and eggshells in China. You also may recall that we've made crazy leaps forward in genetics and genomics. Can we put the two together and create a dinosaur?

Forest-fire prevention has been a touchstone of American consciousness since the creation of Smokey the Bear in the 1940s. But now, environmental experts believe that some amount of fire is good for the forest too.

As far back as 1500 B.C.E., people were trying to purify water to make it drinkable. And we're still at it. Today inventors use tools as simple as clay and as sophisticated as carbon nanotubes to bring clean water to the world.

People all over the world are working on turning this very ancient power source into an even more important modern one. And that means a lot more than dams.

Nobody likes to spend a small fortune fueling up at the pump. Could some minuscule matter change that scenario and the energy sector in general?

From the Hope diamond to the shiny bits in instant coffee, crystals have always held the power to fascinate us humans. Are they more than just a bunch of pretty facets?

Variety isn't just the spice of life; it's the currency of all well-functioning ecosystems great and small. What happens that currency is in trouble?

While nanoparticles and nanocrystals have always existed -- they're even found in volcanic ash -- it was only recently that scientists could manipulate things on the nanoscale. What applications might nanotechnology have in fuel efficiency?

Imagine a different kind of light bulb, one that lasted as long as a fluorescent bulb, but without the buzz, as energy-efficient as a CFL but with a more pleasing light. Meet the FIPEL bulb.

Sometimes the ideas get a little crazy in the race to find clean and inexpensive energy, like tying solar energy to hydrogen production in a palm-sized device. And sometimes those crazy ideas actually work.

Traditional wind power is a promising, through controversial, alternative energy source. But new research is yielding new possibilities: The future of wind may not be in blades, in farms or even fixed to the Earth.

Over the years, many theories have been advanced about why the once-mighty Mayan civilization fell. But a newer one is getting attention: Was it because of climate change?

Farmland, farmland, farmland and ... drilling rig? That's the reality in parts of Pennsylvania, where hydraulic fracking for shale gas is bringing in profits and protests. What do you know about this controversial process?

Have you ever read "Journey to the Center of the Earth" and wondered if it were possible to do it? Well, scientists are in the process of giving it their best shot. How hard is it to dig a hole this deep, and what might they find?

With the world's population expanding and its arable land shrinking, how in the world are we going to have enough food to feed everyone? Here are five ways.

From dinosaur skeletons to petrified wood, fossils help us learn about prehistoric creatures' anatomy and physiology. See pictures of incredible examples of fossils from around the world.

The idea behind a green transportation infrastructure is one that provides opportunities for people to get around their communities using their own power -- such as walking or biking. In this article we 10 ideas for greener transportation.

Agronomists, environmentalists, and economists around the globe have been debating how to feed everyone on it for years and years.
