Odd crests helped dinos communicate

Paleontologists have puzzled over the lambeosaur, an odd-looking duck-billed dinosaur, since its fossils were discovered in 1914. In particular, scientists were curious about the distinctive crest on the lambeosaur’s head: Elongated and complex nasal passages led air from the dinosaur’s nostrils up into the hollow crest and back down into its lungs. But what purpose these nasal passages served was a mystery — until now.

October 31, 1992: Vacation reverses position on Galileo

More than three and a half centuries after the Vatican accused famed Italian astronomer Galileo Galilei of heresy, Pope John Paul II officially welcomed him back into the fold, dismissing the whole messy episode as a “tragic mutual incomprehension.” At issue in what has become known as the “Galileo affair” was planetary motion. In the early 1600s, nearly all Europeans believed that the universe revolved around Earth. Not only was the idea widely supported by most scientists, but scripture seemed to dictate that it was so. Theologians pointed to biblical passages such as Psalm 104 — which proclaims, “[The Lord] set the earth on its foundations; it can never be moved” — as evidence of a geocentric system.

With falling oil prices, short-sellers may win big

Blogging on EARTH

We all heard it this summer: national politicians blasting speculators for driving up oil prices. Journalists and academics may never sort out the actual significance of speculators in this regard.

VA geologists axed due to budget crunch

Virginia, like many states, is being hit hard by the recent economic downturn — and as Virginia tightens the purse strings, the state’s geological survey is going to feel the pinch.

Not surprisingly, geologists in Virginia are not happy.

Virginia expects a $2.5 billion budget shortfall over the next two years. To balance the budget, Virginia’s Gov. Tim Kaine plans to lay off 570 state employees, including nine employees (out of 21) from the state’s Division of Geology and Mineral Resources (Virginia’s equivalent to a state geological survey).

Hot enough for ya? Investigating climate change in "Heat"

In FRONTLINE's urgent, ambitious new special "Heat," producer and reporter Martin Smith takes on a sweeping canvas of climate change, journeying from the disappearing glaciers of the Himalayas to the cement factories of India to the coal mines of the United States. There's a revealing look into the U.S.' role in the climate change conference in Bali last December, as well as into the plans of China's largest car company.

'The Big Necessity' Reclaiming feces

In her new book, "The Big Necessity: The Unmentionable World of Human Waste and Why It Matters," freelance journalist Rose George argues that experts and citizens alike must overcome their aversion to all things fecal — or else face one of the most serious public health risks on the planet. If handled properly, George says, waste water can even be reclaimed as potable water. Recently, EARTH contributor Brian Fisher Johnson talked with George about her book, which was released on Oct. 14.

Arctic soils retain more carbon

Don’t look now, but a slumbering beast rests in the north. It’s not news that the North American Arctic, where trees dare not grow, contains immense amounts of organic carbon in its soils. But according to a new study, past estimates of organic carbon concentrations in Arctic soils are too low — and that has some scientists worried about vast amounts of carbon being released as temperatures warm.

Travels in Geology: Thrills and spills at West Virginia's New River Gorge

When Budget Traveler magazine named Fayetteville, W.Va., one of the “Coolest Small Towns in the USA”, it credited not just the town’s young atmosphere and unique shops, but also the local geology, which is nothing short of spectacular.
