The Chicxulub Crater: Clues to the Demise of 65% of Planet's Species

The popular theory that Mexico's Chicxulub Crater, discovered in 1978, holds the clue to the demise of the dinosaurs, along with some 65 percent of all species 65 million years ago, has been confronted by a serious challenge from Gerta Keller of Princeton University in New Jersey, and Thierry Adatte of the University of Lausanne, Switzerland. The team used evidence from Mexico to suggest that the Chicxulub impact predates the K-T boundary by as much as 300,000 years.

MythBuster Adam Savage's "Obsession": The Real Story Behind His Extinct Dodo Video

It takes an icon to be obsessed with an icon -especially a Mythbuster obsessed with a Victorian icon discovered in 1851 on a remote island off the coast of the Africa in the southwest Indian Ocean. Adam Savage describes himself as "a maker of things. I've built everything from spaceships to buddhas, from puppets to rifles, from sculptures to toys. And just about anything else you can think of."

But we bet you didn't think: Extinct Dodo Bird Replica.

Biologists Say Planet is Undergoing Mass Species Extinction (VIDEO)

Although Earth's islands make up less than four per cent of the planet's land mass, they are home to around a quarter of the world's known plants - 70,000 of which do not exist anywhere else.

“Humanity doesn’t need a moon-base or a manned trip to Mars. We need an expedition to planet Earth, where probably fewer than 10 per cent of species are known to science, and fewer than 1 per cent of those have been studied beyond a simple anatomical description and a few notes on natural history. At the same time, we are engaged in a genocide against those species, known and unknown; the sixth mass extinction has begun."

E.O. Wilson, Harvard evolutionary biologist and author of "The Creation."

Experts say that at least half of the world’s current species will be completely gone by the end of the century. Most biologists say that we are in the midst of an anthropogenic mass extinction. Numerous scientific studies confirm that this phenomenon is real and happening right now. Should anyone really care? Will it impact individuals on a personal level? Scientists say, “Yes!

What Life Might Look Like on Jupiter's Europa: New Extreme Species Discovered

Wonder what life of Jupiter's moon, Europa, might look like? Checkout a  new species of archaebacteria, Pyrococcus CH1,discovered thriving on a mid-Atlantic ridge within a temperature range of 80 to 105°C and able to divide itself up to a hydrostatic pressure of 120 Mpa (1000 times higher than the atmospheric pressure). Alieve won't help down there.

Antarctica Islands Found to Rival Galapagos in Biodiversity

A team from British Antarctic Survey and University of Hamburg combed the land, sea and shores of the South Orkney Islands last year, near the tip of the Antarctic Peninsula, using scuba divers and trawled nets to capture creatures as deep as 1,500 meters.

Is Urban Growth Accelerating the Planet's Bioversity Crisis? -A Galaxy Insight

"Every week humans create the equivalent of a city the size of Vancouver."

A new study outlines the uncomfortable question of what happens to the planet’s biodiversity when cities take over the world. Cities are growing, and they’re growing fast. It is projected that urban growth will create an additional 350,000 square miles of cities roads, buildings and parking lots—covering a combined area the size of Texas—by 2030. Every week humans create the equivalent of a city the size of Vancouver. What will this staggering growth mean for both nature and people?

The Planet's First-ever Mass-Extinction Precipitated by a Biotic Agent: Humans

Should we be alarmed at the current massive die-offs being noted in the animal and plant kingdoms? After all, new species arise and old species die off all the time. Its just nature taking its course, right? Not necessarily. The Earth is now entering the sixth mass extinction event in its four-billion-year history, but what’s different about this die-off is that this is the only such event precipitated by a biotic agent: humans.

What Will Happen to Biodiversity When the World Becomes A Giant City? A Galaxy Insight

A new study outlines the uncomfortable question of what happens to the planet’s biodiversity when cities take over the world. Cities are growing, and they’re growing fast. It is projected that urban growth will create an additional 350,000 square miles of cities roads, buildings and parking lots—covering a combined area the size of Texas—by 2030. Every week humans create the equivalent of a city the size of Vancouver. What will this staggering growth mean for both nature and people? According to the study, co-authored by Conservancy scientists Robert McDonald and Peter Kareiva McDonald, it means significant species loss and a further decline of natural resources like fresh water. They say we need to prepare—now.
