“Big Bang” experiment advancing fast

GENEVA (Reuters) – After a year’s delay, scientists at the world’s biggest accelerator have restarted an experiment to recreate “Big Bang” conditions that had sparked suggestions the earth would be sucked in by millions of black holes.

Scientists at the European Organization for Nuclear Research (CERN) have established circulating particle beams in both directions in the underground Large Hadron Collider, a step that is already beyond where the experiment stalled during a first attempt in September 2008, CERN spokesman James Gillies said.

The high-profile experiment, through which tiny particles are smashed in a bid to learn more about the birth of the universe, failed just nine days after it was launched due to a technical problem that took longer than expected to fix.

“We are further advanced now than where we were after five days of experiment last year,” said CERN’s Director for Accelerators Steve Myers, saying the extra year had allowed researchers to upgrade instrumentations and computer software.

Myers added that researchers had increased the sensitivity of the protections at the 10 billion Swiss franc ($9.82 billion) collider under the French-Swiss border.

“If anything happens, we would not have the same amount of damage we had last year,” he said.

CERN, a 55-year-old organization that counts 10,000 scientists and technicians worldwide working on its research projects, has vigorously rebuffed any suggestion the ground-breaking experiment would cause the world to end.

CERN’s Director General Rolf Heuer said getting the experiment re-started had been an “herculean effort.”

“We’ve still got some way to go before physics can begin, but with this milestone we’re well on the way,” he said.

If things continue to progress at this speed, scientists may be able to accelerate particles at the highest energy level ever tested before Christmas, although high-energy collisions that may shed light on the secrets of the universe would only happen in the new year, Myers said.

The experiment will be fully under way when the particle beams will be smashed at high energy levels. This will most likely happen in January.

The next important step in the experiment will be low-energy collisions, expected in about a week from now, CERN said.

Eating Test Tube Burgers

Eating Test Tube Burgers
from the August 25, 2009 eNews issue

http://www.khouse.org

Food is always big news. From the dangers of a high-McDonald’s lifestyle to the potential cancer-fighting benefits of chocolate, people are always interested in food. In those parts of the world where people don’t necessarily eat every day, a steady food supply is serious business. At the same time, researchers and scientists have developed some bizarre methods for producing food, and the products may or may not be as great as their advertisers claim.

Test Tube Meat:
CNN reports that research group New Harvest has been working on creating “meat” in a laboratory. In an effort to get away from the hassles of animal production, with the space and grain requirements, New Harvest researchers are growing their protein-rich products in steel vats. New Harvest also claims its lab-made meat comes free of the diseases that can be found on normal animal farms.

The process does not require anything exotic like big computers recombining atoms. Nature is still used, after a fashion. The eggs of cows or pigs are collected from a local slaughterhouse. Those eggs are fertilized and the resulting embryos are put in a nutrient solution where they can grow as big and strong as embryos can without a uterus involved. The in-vitro meat can’t replace a chicken leg or steak, but it can work as ground meat, sausages or chicken nuggets.

“Cultured meat would have a lot of advantages,” said Jason Matheny of New Harvest. “We could precisely control the amount of fat in meat. We could make ground beef with an ideal fatty acid ratio — a hamburger that prevents heart attacks instead of causing them.”

Environmentalists and animal rights groups are excited about the prospect of moving the world’s meat supplies from the stockyard to the lab. They visualize a world with no more cramped chicken runs packed with birds that are pumped full of hormones and antibiotics. They imagine rainforests safe from bulldozers because new fields are not needed to grow crops to feed cattle.

One environmental scientist was less than impressed with the plan, however, commenting on the CNN article:

“Animal cells do not manufacture protein out of wishes and moonbeams. There will be a feedstock, likely based mostly on soy and corn to balance the protein content just like animal feed today. It will be heavily chemically processed to break it down into a form muscle cells can use. There will be waste from this process which will be chemically similar to the waste produced by animal digestion. The metabolic processes of the tank meat will also produce waste which will be essentially identical to the waste produced by metabolism in an intact animal.”

In other words, this isn’t a food-from-nothing effort. There will still be feed and waste issues to deal with. We cannot grow in-vitro burgers “in a cup” in space for 700 years while WALL-E stacks our garbage into skyscrapers, fun as that sounds. At the same time, it would seem that, pound for pound, growing embryos would require less feed and would emit less waste than a steer that eats for half a year before it’s slaughtered.

Either way, there is something perverse about eating animal embryos, even coated with sweet and sour sauce. It might not be Soylent Green, but it will still take a long time to convince consumers that in-vitro is all good to eat.

Organic Continues To Thrive:
Test tube chicken nuggets are not the only option. There are other alternatives to hormone-filled chickens squished in cages. As the economy has slowed down, folks have been returning to their own backyards. People with a few acres are taking advantage of their land to let a bullock or two forage during the summer. Gardens grown with heirloom seeds and old-fashioned manure can be guaranteed free of chemicals and genetically modified vegetables. A few happy chickens wandering around the yard not only eat bugs, and poop out natural fertilizer, but they offer hormone-free eggs and even an occasional healthy supper of chicken and dumplings. Feathers are messy, but we all make trades in life.

Organic farms have flourished in recent decades as people shy away from the hormones and chemicals and genetically modified produce that have overtaken supermarket shelves. Even in the cities, rooftop and vacant lot gardens have cropped up. A good supply of tomatoes or basil can be gathered from potted plants on a balcony, and they taste miles better than the ones from the store.

Future Famine?
In Revelation 6:5-6, the Bible speaks of a time when a simple measure of wheat will cost an entire day’s wages. Famines are not new, and there will be some terrible ones in the future. The problem is not lack of resources or overpopulation, however. The majority of famines on earth are man-made. The horrible economic conditions of the future will be caused by mismanagement and corrupt government rather than a lack of land or water, or even of a shortage of embryonic-beef burgers.

The Christian’s Famine Today:
Too many Christians today suffer from malnourishment; we are living in famine conditions but the famine has nothing to do with food. Our famine is like the one that Amos spoke of:

“The days are coming,” declares the Sovereign LORD, “when I will send a famine through the land – not a famine of food or a thirst for water, but a famine of hearing the words of the LORD.” – Amos 8:11

Let’s put as much effort into feeding ourselves with the Word of God as we do putting supper (with or without in-vitro burgers) on the table. After all, man does not live by bread alone.

Earthquake strikes southern Iran

Earthquake strikes southern Iran

Map

An earthquake has struck southern Iran, with hundreds of people suffering injuries, a state news agency says.

There are no reported deaths but about 100 people needed hospital treatment, the Irna news agency said.

The 4.9-magnitude quake in Bandar Abbas sent people streaming into open spaces and cut power cables in the city.

Iran straddles a major geological fault line, making it prone to tremors. In 2008, seven people were killed in an earthquake in the same region.

On average one earthquake hits the country each day, although most are minor tremors and are often in sparsely populated regions.

The deadliest quake to hit Iran in recent years was in 2003, when 25,000 people died in a 6.7-magnitude quake in Bam.

Bandar Abbas is home to a large oil refinery that serves the Iranian domestic market.
