Flashback Aussie Finds Meteorite Crater on Google Earth

Sydney: A rare meteorite impact crater in remote Western Australia has been discovered by an Australian geologist using Google Earth.

The Hickman Crater, located in the Pilbara region around 1000 km northeast of Perth, was named for its discoverer, Arthur Hickman, who was using Google Earth to conduct research on channel ore deposits.

If confirmed, the Hickman Crater will be Australia's second largest preserved rim crater - one that has not eroded significantly from its original shape. The crater's rim, which is 80 per cent preserved, stands 30 m above its floor, and consists mainly of rhyolite, a rock similar to granite.

Florida: Mysterious algae blooms worry biologists

Peter Frezza, a biologist with Audubon of Florida's Keys office, measures water clarity on the Twin Key banks. The photo was taken from just below the surface and reveals the water's green tinge as a result of the algae bloom in parts of Florida Bay.

Algae has turned Florida Bay's waters a murky green, threatening the ecosystem below. What's causing the sudden blooms isn't clear.

Only a day earlier, the heart of Florida Bay's world-renowned fishing ground was clear enough to count turtle grass blades six feet down. Now, Pete Frezza stared into water so thick with algae it looked an awful lot like pea soup.

The colossal squid, which weighs half a tonne, is thought to be the largest ever recovered intact

The sight of an enormous, tentacled creature splayed out on an operating table may seem like the stuff of science fiction, but for scientists in New Zealand tomorrow it will just be another day at the office.

The Museum of New Zealand Te Papa is about to begin experiments on one of the ocean's most enigmatic creatures: the colossal squid. Only dismembered or digested parts of the squid are ordinarily found, but this rare intact specimen was caught in Antarctic waters in February 2007.

17 Elephants Butchered for Ivory in African Park

Poachers from an array of factions have killed 17 elephants in eastern Democratic Republic of the Congo since mid-April, conservationists announced.

The killings of the first 14 animals were announced early last week, and an additional 3 were found Friday.

The rare animals were slaughtered in Virunga National Park, most likely to feed Asia's demand for ivory.

Virunga's ecosystem has come under increasing pressure from a bevy of military groups looking to exploit the natural resources in its jungles to fund their operations.

The Nairobi-based charity WildlifeDirect, which publicized the latest killings, said Rwandan and Mai Mai rebels, Congolese army forces, and even local villagers were all to blame.

At least 17 elephants have been found butchered for their tusks since mid-April in Democratic Republic of the Congo's Virunga National Park, wildlife groups announced.

The toll is rising: At least 15,000 killed by Myanmar cyclone

At least 15,000 people have died since the Nargis tropical cyclone hit Myanmar on Saturday, China's Xinhua news agency quoted official sources as saying Monday.

Earlier Monday, Myanmar's state television said the death toll was nearing 4,000, with around 3,000 people missing.

Authorities in Myanmar introduced a state of emergency in five regions as the cyclone struck, with wind speeds reaching some 190 km/h (118 mph). Most of those killed were in the low-lying Irrawaddy delta.

The majority of the Southeast Asian country's largest city, Yangon, is still without electricity, and its streets are filled with overturned cars, uprooted trees and other debris. Telephone and Internet communications have also been severely disrupted. Several towns around Yangon have also been flooded.

Quake pattern watched closely: How Reno temblors will affect faults at Lake Tahoe unclear

As earthquakes continue to shake Reno, two reports released this month give new insight into the likely characteristics of a temblor at Lake Tahoe.

A 4.2-magnitude quake shook western Reno at 4:33 a.m. Monday, the latest in a series of quakes that has rocked the Mogul area since February.

Monday's quake is considered an aftershock of a 4.7-magnitude quake that hit the area Friday, after which seismologists warned there was a slightly higher probability of a larger quake.

Cyclone kills nearly 4,000 in Myanmar

A devastating cyclone killed nearly 4,000 people and left thousands more missing in army-ruled Myanmar, state media said on Monday, a dramatic increase in the toll from Saturday's storm.

The death toll only covered two of the five disaster zones where U.N. officials said hundreds of thousands of people were without shelter and drinking water in the impoverished Southeast Asian country.

"The confirmed number is 3,934 dead, 41 injured and 2,879 missing within the Yangon and Irrawaddy divisions," Myanmar TV reported three days after Cyclone Nargis, a storm with winds of 190 kph (120 mph), hit the Irrawaddy delta.
