What's The Problem With Feeling On Top Of The World?

Research explores the consequences of boosting self-esteem when it is not justified.

Scientists Come Close To Finding True Magnetic Monopole

Magnets have a north pole, and a south pole. But electromagnetic theory says there should be a bit of matter that is unipolar, that is either north or south pole, but not both. So far the search for the real magnetic monopole has been fruitless, but now physicists at Amherst college have created a synthetic magnetic monopole, something that provides hope that the search for the real thing will ultimately succeed.

Changing Climate In Argentina Is Killing Penguin Chicks

The world's largest breeding colony of Magellanic penguins is seeing unprecedented deaths among young birds. A scientist who has spent 30 years studying the penguins says that climate change is to blame — triggering, among other things, more heat waves and wetter storms that kill fledglings.

Your Nose Knows Which Foods Are Fattiest

Low-fat ice cream just won't cut it for you? Maybe it's your nose telling you it's not the real deal. Researchers have found that people can actually smell differences in dietary fat in food. It's an ability that might have helped our ancestors find the best foods to survive on.

New research shows that a planetary reshuffle might have shaped the ring of rubble between Mars and Jupiter.

Much Of North Dakota's Natural Gas Is Going Up In Flames

Drillers pumping oil on the Great Plains are also producing a lot of natural gas. But the state doesn't have the infrastructure to transport or store it, so much of that gas isn't being sold — it's being set on fire.
