Floods and Landslides Kill 10 in Vietnam

Flooding and landslides caused by heavy rain have killed at least 10 people in Vietnam's northern mountainous provinces near China, the government said on Sunday.

The biggest death toll of five came in Ha Giang province, where people were buried in their homes or swept away in floods, the Hanoi-based national flood and storm control department said in an online statement.

Of the victims, four were children aged between two and 15 years old, the agency said.

Hundreds of houses in five northern provinces have been inundated while roads and crops were severely damaged in up to 300 millimetres (12 inches) of rain, which began falling on Thursday, it said.

At least 10 communes in Bac Giang province have been cut off.

Iowa's Lake Delhi Dam Bursts Due to Flooding

Residents Flee as Rising Floodwater Eats 30-Foot-Wide Hole in the Earthen Dam

The Lake Delhi dam in eastern Iowa failed Saturday as rising floodwater from the Maquoketa River ate a 30-foot-wide hole in the earthen dam, causing water to drop 45 feet to the river below and threatening the small town of Hopkinton.

Northeast Iowa has been inundated with torrential rain in recent days with as much as 9 inches being reported in some locations. The heavy rain has pushed the Maquoketa River to 23.92 feet - more than 2 feet above its previous record of 21.66 feet in 2004.

Jack Klaus, a spokesman with the Delaware County emergency management office, said warning sirens were sounding in Hopkinton as water began to surround homes there Saturday afternoon. Areas below and above the dam had been evacuated, including numerous cabins and homes - as many as 700 - above the dam because of high water.

"There's going to be significant losses of property there," Klaus said.

Baboons Learn to Listen for Cars Central Locking Tweet Before Breaking In

Baboons in Cape Town have learned to listen out for the tweet of a car's remote central locking before deciding whether to break in to search for food, according to the local authorities.

The highly intelligent animals lie in wait as tourists get out of their car to gaze at the view from Cape Peninsula - the thin finger of land in the south westernmost corner of South Africa that juts out into the Atlantic Ocean.

Then, if they haven't heard the telltale "tweet" of the locking system, they sneak over and open the car door to plunder its contents.

So many picnics have now been lost to the simian raiders that the local authorities are pushing the government to commission an official baboon warning road sign as they have done for hippos, elephants, warthogs and kudus.

Theuns Vivian, Cape Town's Destination Development Manager, said humans and baboons would get along fine provided they were equally aware of each other.

Amazon River Dolphins Threatened with Extinction

The pink dolphins of the Amazon are being threatened with extinction as fishermen kill them to use their flesh as bait.

Scientists believe that 1,500 dolphins are being killed annually in the western Amazon to fuel a lucrative trade in catfish, which feeds on dead animals.

"The population of the river dolphins will collapse if these fishermen are not stopped from killing them," said Vera da Silva, the top aquatic mammals expert at the government's Institute of Amazonian Research.

"We've been studying an area of 27,000 acres for 17 years, and of late the population is dropping seven per cent each year."

The dolphins, which can be eight feet long and weigh the same amount as an adult man, are the largest of four species known to exist in South America and Asia. The cause of their pinkish hue is debated, with some scientists saying it is due to blood vessels being close to the skin and others citing scarring as the reason for their coloring.

Forty-Ton Whale Lands on Yacht During Cape Town Sailing Trip

A couple who took a yacht for a quiet sailing trip were stunned when a 40-ton whale crash-landed on their boat off Cape Town.

The pair were enjoying calm seas off the South African coast when the animal flipped into the air and smashed into their mast.

Ralph Mothes, 59, and Paloma Werner, 50, were helpless as the beast thrashed around on their 33ft vessel before slipping back into the water.

Miss Werner said: "It really was quite incredible but very scary. The whale was about the same size as the boat.

"We'd spotted it about 100 metres away and thought that was the end of it. Then suddenly it was right up beside us.

"I assumed it would go underneath the boat but instead it sprang out of the sea. We were very lucky to get through it, as the sheer weight of the thing was huge.

URGENT: State of Emergency Declared in Louisiana, U.S., as Storm Moves Over Oil Spill



Louisiana Gov. Bobby Jindal has issued an emergency declaration, intended to speed state help to parishes that need it after the storm hits. He said mandatory evacuations are not expected, but parishes might call for voluntary evacuations in some low-lying areas.

Mysterious Plague Killing Off Bats, Bugs Get Free Rein

Experts Don't Know How To Stop Spread of Deadly Fungus

A spreading plague has killed more than a million bats across the eastern U.S., and wildlife experts have no clue how to stop it.

As it rolls across the country and into Canada, the mysterious fungus threatens to disrupt the ecological balance, which could result in the spread of bugs that destroy crops and force swatting barbequers to flee indoors.

Called White-Nose Syndrome because of the white substance found on the noses of bats, it causes bats to move around and burn calories during the winter months when they should be hibernating and reserving energy. Scientists are not exactly sure why the fungus affects bats, where it came from originally, or how to stop its spread. One thing is for sure -- bat populations are being decimated by the fungus. Among some bat species, the mortality rate is 99 percent.

"There might be regional extinctions of particular bat species," said Noelle Rayman, assistant national White-Nose Syndrome coordinator at the U.S. Fish and Wildlife Service, told ABCNews.com.

There's a Hole in This Possible Earthquake Pattern

FAULTLINES

The road to Ejido Cucapah, one of several farming villages south of Mexicali, is etched with sinkholes, cracks and buckled pavement.

Los Angeles - As University of California at Davis physicist and geologist John Rundle ponders the map of recent California earthquakes, he sees visions of a doughnut even Homer J. Simpson wouldn't like.

The doughnut is formed by pinpointing the recent quakes in Eureka, Mexicali and Palm Springs.

Seismologists call the possible pattern a Mogi doughnut. It's the outgrowth of a concept, developed in Japan, which holds that earthquakes occur in a circular pattern over decades - building up to one very large quake in the doughnut hole. Rundle and his colleagues believe that the recent quakes, combined with larger seismic events including the 1989 Loma Prieta and 1994 Northridge temblors, could be precursors to a far larger rupture.

They just don't know exactly when.

The idea of predicting earthquakes remains controversial and much debated among California's many seismologists. But as technology improves and the understanding of how earthquakes distribute energy grows, experts are gingerly offering improved "forecasts," some of which have been surprisingly prescient.

For example, Southern California was hit earlier this month by a 5.4 quake that struck in the mountains about 30 miles south of Palm Springs - several weeks after seismologists at the Jet Propulsion Laboratory and elsewhere warned that pressure was building in the San Jacinto fault zone, which is where the temblor occurred.

That forecast underscores new thinking by seismologists about how earthquakes occur.
