The science project that some feared might end the world has encountered some problems.
This Is Really Huge
Of course, problems were to be expected. But this will only fuel the fire for those who continue to worry about the approach of an impending doomsday.
The Hadron Collider will be shut down for two months after just opening .
The giant Large Hadron Collider, the world’s largest and most expensive scientific experiment, will be shut down for at least two months, scientists at the European Center for Nuclear Research, or CERN, in Geneva said today.
The shutdown casts into doubt the hopes of CERN physicists to achieve high-energy collisions of protons in the machine before the end of the year.
“It’s too early to say whether we’ll still be having collisions this year,” James Gillies, head of communications for CERN, said in an e-mail message. The laboratory shuts down to save money on electricity during the winter.
A gala inauguration party scheduled for Oct. 21 will still take place, Dr. Gillies said.
A series of mishaps, including the failure of a 30-ton electrical transformer, have slowed progress since then. In the worst incident yet, on Friday, one of the giant superconducting magnets that guide the protons failed during a test. A large amount of helium, which is used to cool the magnets to within 3.5 degrees Fahrenheit of absolute zero, leaked into the collider tunnel.

 Large Hadron Collider (LHC), the biggest and most complicated particle physics experiment ever seen,
will be turned on Wednesday, September 10th. It took almost 20 years and 7,000 scientists from 60 countries
to create this project. (Hadron Collider)
"Before the year is out, the LHC is projected to begin pumping out a tsunami of raw data equivalent to one DVD (five gigabytes) every five seconds. Its annual output of 15 petabytes (15 million gigabytes) will soon dwarf that of any other scientific experiment in history.The challenge is making that data accessible to a scientist anywhere in the world at the execution of a few commands on her laptop. The solution is a global computer network called the LHC Computing Grid, and with any luck, it may be giving us a glimpse of the Internet of the future. Once the LHC reaches full capacity sometime next year, it will be churning out snapshots of particle collisions by the hundreds every second, captured in four subterranean detectors standing from one and a half to eight stories tall. It is the grid's job to find the extremely rare events—a bit of missing energy here, a pattern of particles there—that could solve lingering mysteries such as the origin of mass or the nature of dark matter."
The Large Hadron Collider will be operated by the European Organization for Nuclear Research, also known as CERN. It is a circular underground tunnel, in which the partical beams ramp up to 99.99 percent of the speed of the light, are more than 300 feet below the earth. This is located at the foot of the Jura Mountains.

Well, who doesn’t like a pretty bird?
I spend a fortune feeding them, that’s how much I like them…Goldfinches in particular.
Are there any other bird lovers out there who can explain to me why the price of thistle seed/Nyjer seed doubled in price this year? Is it just because of shipping costs?
That said....
There really has been a new species of bird discovered. Considering how many species of insects and birds there are in the world, I suppose a new one popping up should be expected. But I find it interesting, expecially when it is as pretty as this little guy...

Welcome to a new species of an African Forest Robin from Gabon…Stiphrornis pyrrholaemus
"Scientists at the Smithsonian Institution have discovered a new species of bird in Gabon, Africa, that was, until now, unknown to the scientific community. Their findings were published in the international science journal Zootaxa, Aug. 15.
The newly found olive-backed forest robin (Stiphrornis pyrrholaemus) was named by the scientists for its distinctive olive back and rump. Adult birds measure 4.5 inches in length and average 18 grams in weight. Males exhibit a fiery orange throat and breast, yellow belly, olive back and black feathers on the head. Females are similar, but less vibrant. Both sexes have a distinctive white dot on their face in front of each eye. "

Brian Schmidt, an ornithologist at the Smithsonian's National Museum of Natural History discovered he had found something new while researching and comparing several different specimens of birds to those already in the Smithsonian's bird collection.
"I suspected something when I found the first bird in Gabon since it didn't exactly match any of the species descriptions in the field guides," said Schmidt. "Once I was able to compare them side by side to other specimens in our collections it was clear that these birds were special. You, of course, have to be cautious, but I was still very excited at the prospect of possibly having found a new species of bird."
The new bird species was first seen in southwest Gabon in 2001during a biological survey of tropical rainforest species.
Smithsonian Scientists Discover New Bird Species
And in keeping with the theme, I’ll end with a very short clip from Alfred Hitchcock’s The Birds, one of my favorite movies.
But I warn you ahead of time of a danger in this clip that was carried throughout the movie…
The main character, played by Tippi Hedren, smokes : ) Just thought I'd warn you since you don't often see that in movies anymore.

Flying while intoxicated? In Space?
Well, I hope not....but who knows what tricks space travel and gravity can do to you.
And, in space?
Well, yes...Sometime soon, Astronauts may be able to enjoy a cold beer after a long day flying, or walking in space.
That could make for an interesting sobriety test.
Could you walk a straight line please?
Touch your finger to your nose?
Anyway, it seems a Japanese brewery, Sapporo Holdings, is putting out the first "space beer" using the third-generation descendants of barley grown on the International Space Station.
Read about it at AFP í here
And let’s hope NASA gets that Space Station toilet working before the beer is ready.

OR Global Warming….
This one will go under global warming, according to “some experts.”
What is it this time?
This....
"Two deaths in the waters off California and Mexico last week and a spate of shark-inflicted injuries to surfers off Florida's Atlantic coast have left beachgoers seeking an explanation for a sudden surge in the number of strikes.
In the first four months of this year, there were four fatal shark attacks worldwide, compared with one in the whole of 2007, according to the International Shark Attack File at the Florida Museum of Natural History in Gainesville."
Read the article from The Guardian Observer
Surge in fatal shark attacks blamed on global warming í here
I guess that's enough to convince me.
How about you?
Nah...it really wasn't.
How about some statistics.
The easiest place to find those...Wikipedia, :
In 2000, there were 79 shark attacks reported worldwide, 11 of them fatal. In 2005 and 2006 this number dropped to 61 and 62 respectively, while the number of fatalities dropped to only four per year. Of these attacks, the majority occurred in the United States (53 in 2000, 40 in 2005 and 38 in 2006). For the same period, the Global Shark Attack File records 69 unprovoked attacks of which five were fatal.
2008 attacks
An Austrian tourist died February 24, 2008 after being bitten by a shark while diving near the Bahamas in waters that had been baited with bloody fish parts to attract the predators.
A 16-year-old Australian boy died on April 8, 2008 after being attacked by a shark in the coastal town of Ballina, on the mid-coast. The boy died whilst bodyboarding when he and a friend were taking advantage of a teacher's strike; the teenager's friend is now being considered for a bravery award. The shark responsible was thought to be a bull shark.
A 66-year-old man died on April 25, 2008 off the coast of the Southern California city of Solana Beach. The species of shark was a great white shark. A 25-year-old man died on April 30, 2008 off the coast of Mexico. The species of shark was a nurse shark.

Why Sharks Attack...
From HowStuffWorks:
Ninety percent or more of shark incidents are mistakes. They assume that we're something that we are not.- Gary Adkison, diver ("Sharkbite! Surviving the Great White")
Although shark attacks can seem vicious and brutal, it's important to remember that sharks aren't evil creatures constantly on the lookout for humans to attack. They are animals obeying their instincts, like all other animals. As predators at the top of the ocean food chain, sharks are designed to hunt and eat large amounts of meat. A shark's diet consists of other sea creatures -- mainly fish, sea turtles, whales, sea lions, and seals. Humans are not on the menu. In fact, humans don't provide enough high-fat meat for sharks, which need a lot of energy to power their large, muscular bodies.
If sharks aren't interested in eating humans, why do they attack us? The first clue comes in the pattern that most shark attacks take. In the majority of recorded attacks, the shark bites the victim, hangs on for a few seconds (possibly dragging the victim through the water or under the surface), and then lets go. It is very rare for a shark to make repeated attacks and actually feed on a human victim. The shark is simply mistaking a human for something it usually eats. Once the shark gets a taste, it realizes that this isn't its usual food, and it lets go.
The shark's confusion is easier to understand once we start to look at things from the shark's point of view. Many attack victims are surfers or people riding boogie boards. A shark swimming below sees a roughly oval shape with arms and legs dangling off, paddling along. This bears a close resemblance to a sea lion (the main prey of great white sharks) or a sea turtle (a common food for tiger sharks).
Shark Sensory System
Attacks have also frequently occurred when humans were spear fishing in ocean waters. Sharks are attracted to the signs given off by dying fish -- the smell of blood in the water and the electrical impulses given off as the fish struggles. Sharks detect these signals with their ampullae of Lorenzini, a set of "detectors" under the skin on a shark's snout. The ampullae are electrically sensitive cells that connect to the skin's surface through small tubes. Once a shark arrives on the scene, it may become agitated and aggressive in the presence of so much food. A hungry, excited shark can easily mistake a human for its usual prey.
There are cases in which sharks seem to attack out of aggression, rather than hunger. Very little is known about shark behavior, but it is believed that some species, including great whites, display dominance behavior over other sharks. This behavior can take the form of "punching" with the snout, or bites that don't do much damage to the tough skin of a shark. Unfortunately, when a shark makes a dominance display toward a human, these "gentle" bites can still cause horrendous damage.
Sometimes, the cause of a shark attack is simple to determine -- the shark is responding to human aggression. Nurse sharks, for example, are generally placid fish that lie still along the bottom of the ocean floor. For some reason, this makes some divers think that it's a good idea to pull their tails. Irritated nurse sharks have taught several divers to keep their hands to themselves. For this reason, shark attack statistics are divided between provoked and unprovoked attacks.
~~~~~~~~~~~~~~
I'm going to go with a theory of more people being in the water or changing patterns of other animal behavior in the waters that have drawn sharks to the areas.
But not global warming.
I can't remember the last year I've had my heat come on in May....but it did this week.
But if people really want to believe global warming is attracting sharks and causing attacks...
Then, get out of the water!

But the Russian Soyuz space capsule, returning to Earth, missed the mark and landed in Kazakhstan, 260 miles away from its target.
The crew included American astronaut, Peggy A. Whitson, and the first South Korean astronaut, Yi So-yeon, a female bioengineering student. They landed safely, but it was not an easy re-entry.
Peggy Annette Whitson – NASA Astronaut
"Officials said the craft followed a so-called ballistic re-entry — a very steep trajectory that subjects the crew to extreme physical force. Mr. Lyndin [a spokesman for mission control] said the crew had experienced gravitational forces up to 10 times those on Earth during the descent."
