Finally, they can

Reverse the Aging Process

 

 

A technique to keep the tips of your chromosomes healthy could reverse tissue ageing. The work, which was done in mice, is yet more evidence of a causal link between chromosome length and age-related disease.

Telomeres, the caps of DNA which protect the ends of chromosomes, shorten every time cells divide. But cells stop dividing and die when telomeres drop below a certain length – a normal part of ageing. The enzyme telomerase slows this degradation by adding new DNA to the ends of telomeres.

Mariela Jaskelioff and her colleagues at the Dana Farber Cancer Institute in Boston, Massachusetts, engineered mice with short telomeres and inactive telomerase to see what would happen when they turned the enzyme back on. These mice had shorter lifespans, atrophied organs and smaller brains than mice that hadn't been engineered.

Four weeks after the team switched on the enzyme, they found that tissue had regenerated in several organs, new brain cells were developing and the mice were living longer.

About time, now time becomes more irrelevant, just like Einstein was trying to accomplish through his laterr theories

Early universe

recreated

in LHC was

superhot liquid

 

 

 

The early universe was an extremely dense and superhot liquid, according to the surprise first findings of the ALICE experimentat the Large Hadron Collider near Geneva, Switzerland.

The experiment to probe the early moments of the universe started up on 7 November, smashing together the nuclei of lead atoms inside the LHC's circular tunnel to produce incredibly dense and hot fireballs of subatomic particles at over 10 trillion °C. The idea behind ALICE is to recreate the exotic, primordial "soup of particles" known as quark-gluon plasma that appeared microseconds after the universe's birth. Gluons and quarks went on to become the constitutive "bricks" of neutrons and protons inside atomic nuclei.

Many models have suggested that the flow of particles from these subatomic fireworks produced in high-energy nuclear collisions should behave like a gas and not a liquid. "These observations keep surprising us," says David Evans of the University of Birmingham, UK, a member of the ALICE team.

A further surprise was the density of subatomic particles created by the smash. One major school of thought suggests there is an upper limit on how many interacting gluons can be packed into a given volume: when this saturation point is reached during a collision, no more new debris particles should therefore be produced.

But to the surprise of the ALICE scientists, the lead ions' mini big bang produced more subatomic particles than expected. "This means that if an upper limit exists, it has not yet been reached at the energies used at LHC," says Evans.

Now our LHC investment is paying off.  Fluid matter fixes many of our Theories about the building blocks of the universe.  String Theory even supports this, but it was dismissed as being impossible.

Milk and Meat from

Clone Animals

Declared Safe to Eat

 

The UK's Food Standards Agency has finally declared milk and meat from cloned animals and their offspring safe to eat.

Yesterday, the FSA's Advisory Committee on Novel Foods and Processes concluded that:

The evidence showed no differences in composition between the meat and milk of conventional animals, clones or their progeny and is therefore unlikely to present any food safety risk.

But the statement clashes with the European Commission's (EC) position on food products from cloned animals - that they should be banned altogether.

The FSA's chief scientist, Andrew Wadge, said that the EC's position will be taken into account before the UK government is officially advised.

Meat and milk from cloned animals and their offspring was declared safe by the US Food and Drug Administration in 2007, and farmers in the US, South America and Asia are free to breed from cloned animals.

In the UK, however, the sale of cloned meat - classed as a novel food - requires special authorisation. So this summer, when The New York Times reported that an unnamed British farmer claimed to be selling milk from cloned animals, the debate over the safety and ethical implications of cloning kicked off.

Despite the FSA's statement, clone critics are sticking to their guns. "There are many unanswered questions on the issue of cloning animals - both ethical and practical - and insufficient regulation," a Soil Association spokeswoman told the BBC. "Not only does cloning have a negative impact on animal welfare, we also have no long-term evidence for the impacts on health.

 

The UK was our last bastion of safety, this can't be good in the long run, cloning and making copies can only last a few times before the cloning breaks down and causes mutation that we will be consuming.

Anti-Matter

Trapped at CERN

First Time in History

 

 

Physicists working at the European Organization for Nuclear Research (CERN) in Geneva, Switzerland, have succeeded in trapping antihydrogen — the antimatter equivalent of the hydrogen atom — a milestone that could soon lead to experiments on a form of matter that disappeared mysteriously shortly after the birth of the universe 14 billion years ago.

 

The first artificially produced low energy antihydrogen atoms — consisting of a positron, or antimatter electron, orbiting an antiproton nucleus — were created at CERN in 2002, but until now the atoms have struck normal matter and annihilated in a flash of gamma-rays within microseconds of creation.

The ALPHA (Antihydrogen Laser PHysics Apparatus) experiment, an international collaboration that includes physicists from the University of California, Berkeley, and Lawrence Berkeley National Laboratory (LBNL), has now trapped 38 antihydrogen atoms, each for more than one-tenth of a second.

Now we are getting our moneys worth out of the LHC, lets hope it does not destroy the earth.

Amazing HD Flying Camera

 

 

 

With the help of the Swinglet CAM you can create your very own local aerial map a la Google Maps, or monitor wildlife distribution in a given area, or maybe just get a feel for what’s going on in the neighborhood. The small, unmanned aerial vehicle can take off and land on its own and its integrated camera will snap high resolution images along a predetermined flightpath or as directed by remote control.

Swiss sensor manufacturer senseFly sees the Swinglet CAM high resolution aerial photography drone being useful for such things as traffic monitoring, security applications, mapping, crop monitoring and wildlife watching. It comes packed in a suitably-sized case, has a wingspan of 80cm (31.4 inches) and weighs 500g (17.6 ounces). Its Li-polymer battery will power the UAV for 30 minutes which is said to give it an operational range of up to 20km (12.4 miles) and a top speed of 30-50kph (up to 30mph).

Full Mobile Body Scanners

Near your Home

As the privacy controversy around full-body security scans begins to simmer, it’s worth noting that courthouses and airport security checkpoints aren’t the only places where backscatter x-ray vision is being deployed. The same technology, capable of seeing through clothes and walls, has also been rolling out on U.S. streets.

American Science & Engineering, a company based in Billerica, Massachusetts, has sold U.S. and foreign government agencies more than 500 backscatter x-ray scanners mountedin vans that can be driven past neighboring vehicles to see their contents, Joe Reiss, a vice president of marketing at the company told me in an interview. While the biggest buyer of AS&E’s machines over the last seven years has been the Department of Defense operations in Afghanistan and Iraq, Reiss says law enforcement agencies have also deployed the vans to search for vehicle-based bombs in the U.S.“This product is now the largest selling cargo and vehicle inspection system ever,” says Reiss.

 

Just how your government wants you, with a little dose of Radiation, exposed over and over again.  If you do not fly or have a problem with airport scanners, now they are coming to your neighborhood, to be used over and over again.

New Bike Design Wins

over the World

 

Milan-based Danishdesigner Nils Sveje describes Bike 2.0 as the next generation bicycle… hence the name. At first glance, it looks pretty ordinary. Its very Spartan appearance doesn’t exactly turn heads, and in fact it’s the lack of external features that gives away the fact that this is no ordinary bike.

Instead of a chain, the bike has a pedal-powered internal generator that’s wired directly to the rear hub motor. Instead of derailleurs, it has a stepless gearbox. Instead of brake levers and discs, it has a regenerative coaster brake. And, instead of shifters, it has two wireless rings on the handlebar.

Regular propulsion is achieved via the bottom bracket-mounted generator, that creates power which is sent back to the 500 W brushless motor. Using the “superconductor” (which one would assume is a capacitor), however, the rider can get power boosts when needed. An Intelligent Cadence Leveling feature keeps the rider pedaling at the same speed, via a continuously-variable transmission. The rider initially sets their desired cadence using one of the handlebar control rings.

Interesting Design, strange how the basic bike design has not changed in over a 100 years.

U.S. Chamber of

 

Commerce seeks

 

trial on global warming

 

 

 

 

The nation's largest business lobby wants to put the science of global warming on trial.

The U.S. Chamber of Commerce, trying to ward off potentially sweeping federal emissions regulations, is pushing the Environmental Protection Agency to hold a rare public hearing on the scientific evidence for man-made climate change.

Chamber officials say it would be "the Scopes monkey trial of the 21st century" -- complete with witnesses, cross-examinations and a judge who would rule, essentially, on whether humans are warming the planet to dangerous effect.

"It would be evolution versus creationism," said William Kovacs, the chamber's senior vice president for environment, technology and regulatory affairs. "It would be the science of climate change on trial."

Maybe some real decisions will come from this.

Proof of Life On Mars?

 

 

 

  THIS mysterious monument could be proof there was once life on Mars.

The rectangular structure — measuring five metres across — was photographed by a super high resolution camera on the Mars Reconnaissance Orbiter. The giant monolith juts out of the planet’s surface casting a huge shadow below. Its emergence on website Lunar Explorer Italia has got space buffs speculating if it could have been constructed by creatures once living on the red planet. The monument resembles the black monolith seen in Stanley Kubrick film 2001: A Space Odyssey.

In the movie the structure is believed to be a key to man’s evolution. And astonishingly Buzz Aldrin, the second man to walk on the Moon, revealed a similar monolith was detected on Mars’ moon Phobos. Speaking last week, he insisted: “We should visit the moons of Mars. “There’s a monolith there – a very unusual structure on this little potato shaped object that goes around Mars once every seven hours.

“When people find out about that they are going to say, ‘Who put that there? Who put that there?’”

Feds Finally Admit Chipped Passports

 

Are Not Secure, They Say it is Your Own

 

Fault if Data is Stolen

 

To protect against skimming and eavesdropping attacks, federal and state officials recommend that Americans keep their e-passports tightly shut and store their RFID-tagged passport cards and enhanced driver’s licenses in “radio-opaque” sleeves.

That’s because experiments have shown that the e-passport begins transmitting some data when openedeven a half inch, and chipped passport cards and EDLs can be read from varying distances depending on reader technology.
[...]
Gigi Zenk, a spokeswoman for the Washington state Department of Licensing, says the envelope her state offers with the enhanced driver’s license “ensures that nothing can scan it at all.” But that wasn’t what researchers from the University of Washington and RSA Laboratories, a data security company in Bedford, Mass., found last year while testing the data security of the cards. The PASS card “is readable under certain circumstances in a crumpled sleeve,” though not in a well maintained sleeve, the researchers wrote in a report. Another test on the enhanced driver’s license demonstrated that even when the sleeve was in pristine condition, a clandestine reader could skim data from the license at a distance of a half yard.

Will Americans consistently keep their enhanced driver’s licenses in the protective sleeves and maintain those sleeves in perfect shape – even as driver’s licenses are pulled out for countless tasks, from registering in hotels to buying alcohol? The report’s answer: “It is uncertain … ”

And when the sleeves come off, “you’re essentially saying to the world, ‘Come and read what’s in my wallet,’” says Marc Rotenberg, executive director of the Electronic Privacy Information Center in Washington, D.C. By obliging Americans to use these sleeves, he says, the government has, in effect, shifted the burden of privacy protection to the citizen.

 

Once anything Electrical is made, then it can be stolen.  When will they (we) learn???

Climate change: The sun and the

*

oceans do not lie

*

The moves now being made by the world's political establishment to lock us into December's Copenhagen treaty to halt global warming are as alarming as anything that has happened in our lifetimes. Last week in Italy, the various branches of our emerging world government, G8 and G20, agreed in principle that the world must by 2050 cut its CO2 emissions in half. Britain and the US are already committed to cutting their use of fossil fuels by more than 80 per cent. Short of an unimaginable technological revolution, this could only be achieved by closing down virtually all our economic activity: no electricity, no transport, no industry. All this is being egged on by a gigantic publicity machine, by the UN, by serried ranks of government-funded scientists, by cheerleaders such as Al Gore, last week comparing the fight against global warming to that against Hitler's Nazis, and by politicians who have no idea what they are setting in train.

What makes this even odder is that the runaway warming predicted by their computer models simply isn't happening. Last week one of the four official sources of temperature measurement, compiled from satellite data by the University of Huntsville, Alabama, showed that temperatures have now fallen to their average level since satellite data began 30 years ago.

 

Faced with a "consensus" view which looks increasingly implausible, a fast-growing body of reputable scientists from many countries has been coming up with a ''counter-consensus'', which holds that their fellow scientists have been looking in wholly the wrong direction to explain what is happening to the world's climate. The two factors which most plausibly explain what temperatures are actually doing are fluctuations in the radiation of the sun and the related shifting of ocean currents.

Two episodes highlight the establishment's alarm at the growing influence of this ''counter consensus''. In March, the US Environmental Protection Agency (EPA), which has a key role in President Obama's plans to curb CO2 emissions, asked one of its senior policy analysts, Alan Carlin, to report on the science used to justify its policy. His 90-page paper recommended that the EPA carry out an independent review of the science, because the CO2 theory was looking indefensible, while the "counter consensus'' view – solar radiation and ocean currents – seemed to fit the data much better. Provoking a considerable stir, Carlin's report was stopped dead, on the grounds that it was too late to raise objections to what was now the EPA's official policy.

Meanwhile a remarkable drama has been unfolding in Australia, where the new Labor government has belatedly joined the "consensus'' bandwagon by introducing a bill for an emissions-curbing "cap and trade'' scheme, which would devastate Australia's economy, it being 80 per cent dependent on coal. The bill still has to pass the Senate, which is so precisely divided that the decisive vote next month may be cast by an independent Senator, Stephen Fielding. So crucial is his vote that the climate change minister, Penny Wong, agreed to see him with his four advisers, all leading Australian scientists.

People are begining to re-think this Global Warming, the melting ice has not brought sea levels rising and it had not been getting warmer recently, only cooler.

Russians order Flight Changes, after Massive Magnetic

Shift downs Airliners...

  

Reports circulating in the Kremlin today are saying that Russian Air Force Commanders have issued warnings to all of their aircraft to exercise “extreme caution” during flights “in and around” an area defined as Latitude 17 North [North Atlantic Ocean] Latitude 3 South [South Atlantic Ocean] to Latitude 8 North [Indian Ocean] Latitude 19 South [Indian Ocean] between the Longitudes of 46 West, 33 West, 46 East and 33 East, and which covers the greater part of the African Tectonic Plate.

The reason for this unprecedented warning, these reports state, are the rapid formations of “geomagnetic storms” emanating from the boundaries of the African Tectonic Plate that due to their intensity have caused the loss of two major passenger aircraft during the past month leaving nearly 300 men, women and children dead.

The first aircraft to be downed by this phenomenon was Air France passenger flight 447, and which these reports say that upon encountering one of these geomagnetic storms, on June 1st, near the western boundary of the African Tectonic Plate close to Brazil’s Fernando de Noronha Islands, was “completely annihilated” causing the deaths of 216 passengers and 12 crew members as their plane plunged in pieces into the Atlantic Ocean.

The possible death of Science in the United States.

Scientist tour the Museum of Creation.

 

 

Paleontologists visiting the Creation Museum at the conclusion of a convention got more than they bargained for when they found their life’s work under attack.

After having a few laughs and taking some pictures, most were surprised and offended to see the way in which evolution was being ridiculed by the museum, which some call a “creationist Disneyland”.

“It’s sort of a monument to scientific illiteracy, isn’t it?” Jerry Lipps, professor of geology, paleontology and evolution at University of California, Berkeley, told the AFP news agency. “Like Sunday school with statues… this is a special brand of religion here. I don’t think even most mainstream Christians would believe in this interpretation of Earth’s history.”

Some 715,000 patrons have visited the $27 million museum since it opened in mid-2007 to “bring the pages of the Bible to life.” The 70,000 square-foot facility presents a literal interpretation of the Bible, and suggests that disbelief of this view leads to moral relativism and the breakdown of social values.

University of Akron paleontology professor Lisa Park was moved to tears as she walked down a hallway displaying flashing images of war, famine and natural disasters that the museum blames on belief in evolution.

“I think it’s very bad science and even worse theology — and the theology is far more offensive to me,” Park told the AFP news agency.
[...]
Howard University anatomy professor Daryl Domning shook his head several times throughout his tour of the museum. “This bothers me as a scientist and as a Christian, because it’s just as much a distortion and misrepresentation of Christianity as it is of science,” he told the AFP. “It’s not your old-time religion by any means.” 

 

$250,000 spent on a 60-foot tall Jesus statue. $27 million spent on a Creation "museum," not to mention all the hours of donated labor. Meanwhile, our kids are failing to learn even basic science knowledge in school. Disheartening to a scientist, to say the least.

What is Higgs Boson?

 

The theories and discoveries of thousands of physicists over the past century have resulted in a remarkable insight into the fundamental structure of matter: everything in the Universe is found to be made from twelve basic building blocks called fundamental particles, governed by four fundamental forces.

Our best understanding of how these twelve particles and three of the forces are related to each other is encapsulated in the Standard Model of particles and forces. Developed in the 1960s and 70s, it has successfully explained a host of experimental results and precisely predicted a wide variety of phenomena. Over time and through many experiments by many physicists, the Standard Model has become established as a well-tested physics theory.

DIY Guy Builds His Own PC, 



Intel’s fabrication plants can churn out hundreds of thousands of processor chips a day. But what does it take to handcraft a single 8-bit CPU and a computer? Give or take 18 months, about $1,000 and 1,253 pieces of wire.

Steve Chamberlin, a Belmont, California, videogame developer by day, set out on a quest to custom design and build his own 8-bit computer. The homebrew CPU would be called Big Mess of Wires or BMOW. Despite its name, it is a painstakingly created work of art.

The BMOW is closest in design to the MOS Technology 6502 processor used in the Apple II, Commodore 64 and early Atari videogame consoles. Chamberlin designed his CPU to have three 8-bit data registers, a 24-bit address size and 12 addressing modes. It took him about a year and a half from design to finish. Almost all the components come from the 1970s- and 1980s-era technology.

The BMOW isn’t just a CPU. Chamberlin added a keyboard input, an LCD output that shows a strip of text, a USB connection, three-voice audio, and VGA video output to turn it into a functioning computer.

They want to Rename the "God Particle"

 

 

I once asked a brilliant physicist at Manchester University what he thought of the name the media use for the Higgs boson, the mysterious particle that is regarded as the universal origin of mass. That name, of course, is the God particle.

It is partly with thanks to names like “God particle” and spurious end-of-the-world scenarios that the Large Hadron Collider at Cern near Geneva got so much coverage when it was switched on last year. And broke…

But back to the physicist in Manchester. He paused. He sighed. And then he said: “I really, really don’t like it. It sends out all the wrong messages. It overstates the case. It makes us look arrogant. It’s rubbish.” He then added: “If you walked down the corridor here, poked your head into people’s offices and asked that question, you would likely be struck by flying books…”

Below I’ve set out the best criteria I can find for how to come up with a good name for a new particle. Depending on the number of entries, we’ll select the winner by: consulting physicists; testing the entries on the humanities graduates who run the Guardian’s newsdesk, aka “The Gate Keepers”; or by printing them out on a sheet of paper and asking the chef to throw a dart at it*.

The winner will receive a copy of Science: A Four Thousand Year History by Patricia Fara, and a surprise Higgs boson-themed gift.

Three simple rules:

1) Names should be serious and accurate
2) It is good to name things after people, but only if you can resist the pressure to hyphenate with two or three extra names
3) Names should be evocative and inspiring.
