Because wolves were once on the verge of extinction they were reintroduced into Yellowstone National Park. With the recovery of the wolf population federal protection will end later this month. Therefore, in order to keep track of wolf population a new technology will be introduced. It is called the Howlbox. The Howlbox will emit "wolf howls", that will fool wolves into responding to these calls. With audio software scientists will be able keep track of packs of wolves, as well as individual wolves.  read more »

Maybe nice guys don't finish last; at least, according to a study done by the Harvard University. The research showed that after many iterations of a game, players that chose to punish ended up the losers.

The experiment involved a game of Prisoner's Dilemma with an added twist. This Rock, Papers, Scissors style game is based on the premise that two people are caught by the police and in the classic form of the game, each of the two players has a choice to either cooperate, or defect.  read more »

Invasive plants are one of the major dangers facing the American environment. Foreign plants introduced into our environment often destroy the local vegetation and can cause serious problems to an area's ecological habitat. In Yellowstone, the Canada thistle is changing the ecosystem of that area with surprising results. The rapid spread of the Canadian thistle has brought about an increase in the population of the grizzly bear and gophers, which thrive on the plant. Animals that can take advantage of a new food supply would prosper,however the danger is to species that can't adapt.  read more »

With demands for energy continually rising and the price for oil and gas ever increasing solar power could be the answer. We are not talking about the kind that use panels on homes to produce power. This type would use mirrors to cover acres of desert to produce steam, by directing sunlight on a fluid, and powering turbines, which would produce electricity. There is still a long way to go, but plans are being made to construct ten new plants. Two prototype thermal plants were opened with the capacity to have the ability to power large hotels in Las Vegas.  read more »

We know the impact pollution has had on land and our atmosphere. Scientists are now looking at the impact of pollutions on our oceans. Scientist are discovering that agricultural runoffs and sewage, which are just a few of the ways we pollute our oceans, are having disastrous effects on our seas. About 40% of oceans areas are strongly effected. Waters that were once pristine are no longer so. Invasive species endanger indigenous species, causing great concern for their survival.  read more »
