The deserts of Namibia hold many unusual geological structures that stretch the imagination and defy conventional explanation. Are electric discharges responsible for their formation?
Little Rock (AP) - More rain will fall in Arkansas during the week, likely adding more water to already flooding rivers in the state's eastern sections.
The Flinders Range contains some of the most unusual geological formations in Australia. Indications of gigantic electric arcs are unmistakable.
In several previous Picture of the Day articles we have considered the geological history of the Australian continent and found that there are several disconformities in the appearance and structure of many formations. The famous "Red Center" is particularly noteworthy because Uluru, Kata Tjuta and other monolithic stone tors stand in isolated grandeur above the relatively flat landscape.
The Flinders Range is a rugged outcrop of sandstone and quartzite that begins about 250 kilometers north of Adelaide and stretches for 800 kilometers. The mountains are extensively folded and fractured, with several deep gorges cut through them. One of the most unusual features in the range is Wilpena Pound, a natural amphitheater of stone covering 83 square kilometers, with interior dimensions of 11 kilometers by 8 kilometers.

The dog was chained up in the backyard when the Africanized honey bees attacked.
The dog's owner Chantel Armenta tried to get him free but could not, and when she ran in the house, the bees followed, stinging her and her husband.
Her husband is allergic to bee stings and had to be rushed to the hospital. He is expected to live, but the dog may not.

A man is fighting for his life in hospital after he was stung more than 1 000 times by African honey bees at a Drummond farm on Wednesday.
A paramedic who rushed to the man's aid was also stung several times and was admitted to hospital briefly after he showed signs of a severe allergic reaction to the stings.
Netcare 911 spokesperson Chris Botha said that when paramedics arrived they saw a man collapsed on the ground.
"When the paramedics got out of their ambulance they realised a large swarm of African honey bees was incensed and had stung the man repeatedly. The bees continued to swarm around the man.

Researchers at Texas A&M University have confirmed for the first time that a "dead zone" has existed off the Texas coast for at least the past 23 years and will likely remain there, causing potential harmful effects to marine life in the area.
Steve DiMarco, associate professor in Texas A&M's College of Geosciences who has studied dead zones in the Gulf of Mexico for more than 15 years, believes the dead zone area off the Texas coast extends from the Texas-Louisiana border area to Brownsville. A dead zone occurs when there is hypoxia, or oxygen-depleted water.
Such low levels of oxygen are believed to be caused by pollution from farm fertilizers as they empty into rivers and eventually the Gulf, or by soil erosion or discharge from sewage treatment plants.
"Not all of the area from the Texas-Louisiana coast to Brownsville is a dead zone area, but very much of it is," DiMarco explains. "The Texas dead zone appears to be more patchy and not as continuous as the Louisiana dead zone to the east, but much of the region there has very low oxygen levels, some extremely low."

The California winter has been a tough one on South Dakota beekeepers like Richard Adee.
Last fall he sent 155 semitrailer trucks to California loaded with hives containing bees fit and ready to pollinate the almond crop.
"We lost 40% of the hives we sent there. We sent 70,000 out and lost 28,000," said Adee, whose Adee Honey Farms in Bruce is considered the largest beekeeping operation in the nation.
"I would say overall the losses of South Dakota bees - from what I've heard - from what they started in the spring of '07 until they came out of the almonds is at least 50%. It's not good."
Now, in preparation for the honey-making season in South Dakota, he's working to get back to full strength from a mystery called colony collapse disorder.
