According to the latest rumors whirling through the world physics community, scientists at the LHC are seeing a signal that could correspond to a Higgs particle with a mass of 125 GeV (a proton is slightly less than 1 GeV).
CERN is scheduled to discuss the latest results from ATLAS and CMS, two of the main LHC experiments, on Dec. 13, following a one day after a closed-door CERN council meeting where officials will get a short preview of their results and discoveries to date.
Rumors rippling through the CERN community suggests that results on the elusive Higgs — which is required under the Standard Model of particle physics to provide mass to different particles — will below the five-sigma threshold needed to definitively declare a discovery in physics.
But if the rumors are true, and the Higgs has been seen at 125 GeV, it could bolster the idea that there is physics beyond the Standard Model that describes the behavior of subatomic particles requiring more complex theories, such as supersymmetry, which requires the existence of a heavier partner to all known particles.

There are ancient Principles that embody the truth that there is a harmony, agreement, and correspondence between the several planes of Manifestation, Life and Being.
This truth is a truth because all that is included in the Universe emanates from the same source, and the same laws, principles, and characteristics apply to each unit, or combination of units, of activity, as each manifests its own phenomena upon its own plane.

October 1, 2011
.
After smashing atoms together for 26 years, the Tevatron particle accelerator powered down on Friday. The 4-mile-long ring-shaped accelerator, located at the Fermi National Accelerator Laboratory in Batavia, Ill., was built to hurl tiny bits of matter at each other in the hopes that they would break apart into the basic building blocks of the universe. Though the Tevatron made major discoveries, it became essentially obsolete after the Large Hadron Collider in Geneva began conducting experiments in 2009.
University of Pisa physicist Giovanni Punzi has worked at the Tevatron since it generated its first collisions in 1985. He talked about the Tevatron on Wednesday, two days before it was shut down.
What made the Tevatron special?
The Tevatron was the highest-energy collider in operation for a very long time.
What does the Tevatron do?
It collides protons and antiprotons. We have particle detectors situated where we can analyze the products of these collisions and find what new particles are there.
Why would you want to do this?
When you get the highest possible energy in collisions of particles, you reproduce a level of energy that doesn't exist today. It only existed at a very early stage in the universe, after the big bang. Creating such energies lets you see new phenomena — including particles that are not found in ordinary matter. So you can study the very basic laws that underlie everything we see and are at the basis of the evolution of the universe.
It's a frontier of knowledge. You get to see things that have never been seen.
What did the Tevatron find that had never been seen?
A number of observations and precision measurements that have added to our understanding of high-energy physics. And the top quark was discovered here in 1995. That was a very big discovery.
Why was it important to find the top quark?
The top quark was crucial because without it, all of our theories of how subatomic particles behave wouldn't work. Quarks are the fundamental particles that combine to make protons and neutrons, and physicists knew there had to be a sixth quark. Everybody was puzzled by the fact that we couldn't find it. The reason we couldn't find it is because its mass was so large that scientists could not produce it until the Tevatron came along.
It was a very long search. If we had not found the top quark, understanding all of the rest of the physics would have been a problem.
How did physicists study basic particles before the Tevatron was built?
Before this machine they had proton-antiproton colliders at CERN [the European Organization for Nuclear Research] in Geneva, but they operated at lower energies.
I remember people saying it would be impossible to put together a thousand magnets and make them work at the same time. But the people here did it. People get used to the idea of doing something that yesterday was considered impossible. It pushes everybody to their best.
Now, of course, the record is going back to Geneva because CERN has built an even bigger machine — the Large Hadron Collider. It's 31/2 times more energetic than the Tevatron.
The Tevatron played a big role in the search for the elusive Higgs boson, the so-called "God particle" that gives rise to mass.
Yes — the Tevatron was able to restrict the possible mass of the Higgs boson to quite a small range.
And even though the collider will no longer operate, you'll continue that search?
Yes. We've used just a fraction of the data we have, and we've been improving analysis techniques over time. So now we want to give it our best possible shot and see what we can figure out about the Higgs boson.
The Large Hadron Collider is also looking for the Higgs. But we look for different modes of decay of the Higgs boson: two different faces of the same coin. Even if the Higgs is seen in Geneva, being able to see it here will be very important to confirm and to understand the nature of this particle, which up to now is completely mysterious. We will be certainly adding to the knowledge of this thing.
Who decided to shut down the Tevatron?
The Department of Energy (which operates Fermilab) and the lab directors decided it was time to go into new projects. We proposed last year to keep going and take some more data, but the decision was to begin exploring what's known as the "intensity frontier."
What does that mean?
Rather than going for the highest-possible energy of collisions, we will go for very intense beams with very large numbers of particles. Using these, Fermilab will produce a large number of collisions that will let scientists look for very rare processes. What they cannot make in terms of energy they try to make up in terms of intensity and frequency of the collisions.
There are a whole lot of things that have been developed here, especially on the side of neutrino physics, that require very intense beams.
Last week, physicists at CERN reported that they had measured neutrinos traveling faster than the speed of light. Scientists around the world are now trying to see if they can replicate that result — including a team at Fermilab, right?
Yes. This raised lots of discussion. Most of us were thinking this is too strange to be true. If it is really true it's a violation of the fundamental laws of physics. It's really beyond anything we've seen in the past.
What will happen during the shutdown on Friday?
We'll simply stop doing what we've been doing. People will turn off the accelerator and turn off our detectors. Then we will concentrate on trying to get the final results from the data we've already collected.
How long will that take?
It depends on how interesting the results are. In principle it can go on for several years without a problem, but I anticipate that most of the things will probably come within a couple of years, no more.
Are people at Fermilab emotional this week?
How can't you be emotional when it's been so long and such a successful program? As I said, we have a group of people who are still willing to do more. People never got bored, for all this time.
How many colliders remain in the world?
Well, we have this very big one in Geneva. Apart from that we have smaller machines for doing specialized kinds of physics.
What will become of the Tevatron itself?
It's my understanding that Fermilab will reuse some pieces for the next accelerator and put others on display in a museum.

Puzzling results from Cern, home of the Large Hadron Collider, have confounded physicists because subatomic particles seem to have beaten the speed of light.
Neutrinos sent through the ground from Cern toward the Gran Sasso laboratory 732km away in Italy seemed to show up a tiny fraction of a second early.
The result - which threatens to upend a century of physics - were put online for scrutiny by other scientists.
In the meantime, the group says it is being very cautious about its claims.
They will be discussing the result in detail in a conference at Cern on Friday afternoon, which can be viewed online.
"We tried to find all possible explanations for this," said report author Antonio Ereditato of the Opera collaboration.
"We wanted to find a mistake - trivial mistakes, more complicated mistakes, or nasty effects - and we didn't," he told BBC News.
"When you don't find anything, then you say 'Well, now I'm forced to go out and ask the community to scrutinise this.'"
Caught speeding?
The speed of light is the Universe's ultimate speed limit, and much of modern physics - as laid out in part by Albert Einstein in his theory of special relativity - depends on the idea that nothing can exceed it.
Thousands of experiments have been undertaken to measure it ever more precisely, and no result has ever spotted a particle breaking the limit.
But Dr Ereditato and his colleagues have been carrying out an experiment for the last three years that seems to suggest neutrinos have done just that.
Neutrinos come in a number of types, and have recently been seen to switch spontaneously from one type to another.
The team prepares a beam of just one type, muon neutrinos, sending them from Cern to an underground laboratory at Gran Sasso in Italy to see how many show up as a different type, tau neutrinos.
In the course of doing the experiments, the researchers noticed that the particles showed up 60 billionths of a second sooner than light would over the same distance - a tiny fractional change, but a consistent one.
The team measured the travel times of neutrino bunches some 15,000 times, and have reached a level of statistical significance that in scientific circles would count as a formal discovery.
But the group understands that what are known as "systematic errors" could easily make an erroneous result look like a breaking of the ultimate speed limit, and that has motivated them to publish their measurements.
"My dream would be that another, independent experiment finds the same thing - then I would be relieved," Dr Ereditato said.
But for now, he explained, "we are not claiming things, we want just to be helped by the community in understanding our crazy result - because it is crazy".
"And of course the consequences can be very serious."Puzzling results from Cern, home of the Large Hadron Collider, have confounded... more

Christ Consciousness, can be defined as a state of awareness within ones’ consciousness. Where a blending of the human evolutionary mind (ego), with the divine mind (spirit) and the universal awareness of consciousness is transformed into a higher self state of consciousness (divinity). Thus arriving at the highest state of intellectual development and emotional maturity, termed the “Christ State.” This name reflects to the sacredness and purity of the individual who has ascended into this superior spiritual realm while on earth.
Christ is revered as a universal symbol of the physical and spiritual manifestation of the eternal, pure, and unconditional love of God. However, Christ, is a threefold entity. Firstly, the historic ‘Christ Jesus of Nazareth’, who attained the Christ consciousness through the ‘flesh’; secondly, the ‘Christ Higher Self’ that exists within the spiritual heavens and is our own personal inner teacher that guides us through intuition and higher thought as the ‘living word of God’; and thirdly, the ‘Christ Consciousness’, which is the Collective Christ Consciousness and is, symbolically, the ‘Sun/Son of God’.Christ Consciousness, can be defined as a state of awareness within ones’... more

NASA spacecraft offers detailed views of Saturn's Great White Spot
The Great White Spot, which occurs about once every 30 Earth years, is a windy, towering cloud of ammonia and water spewing out super jolts of thunder and lightning. The storm is about 10,000 times stronger than those on Earth.

July 6, 2011, 6:27 p.m.
Saturn's Great White Spot, a recurring storm on that planet that has intrigued scientists since it was first observed in 1876, is a windy, towering cloud of ammonia and water spewing out super jolts of thunder and lightning. Now astronomers and NASA's Cassini spacecraft, which has been orbiting Saturn since 2004, have captured the most detailed views to date of the phenomenon.
The luminous storm, which may be the gaseous planet's main mechanism for dissipating heat, occurs about once every Saturnian year, the equivalent of about 30 Earth years. The storms, however, do not follow a precise schedule. The latest round, the most intense on record, was first noticed by ground-based professional and amateur astronomers as a bright speck on Saturn's northern hemisphere on Dec. 5, about nine years before schedule. The previous storm occurred in 1990.
Their observations coincided with Cassini's detection of a deluge of radio waves emitted by Saturn. These radio waves are a signature of lightning and can be used as a measure of its strength.
During the days that followed, that small blemish, moving westward about 65 mph, grew to a size nearly equal to the diameter of the Earth. Two months later, the behemoth had blanketed the entire planet, spanning more than 180,000 miles.
"It turned into a very spectacular storm, with so many [lightning flashes] we couldn't resolve individual ones," said Donald Gurnett, a physicist at the University of Iowa and a contributing author of one of two reports published Wednesday in the journal Nature.
This massive eruption of lightning is caused when heat and water vapor rise from deep within Saturn's atmosphere up to its troposphere, the region of the atmosphere where weather occurs. When that water vapor cools and condenses, it releases heat and, under the right conditions, produces lightning.
The lightning on Saturn originates deep inside the planet's atmosphere, where vapors are at higher pressure. That makes the lightning very intense.
The images and measurements gave scientists new insight into the shape of the current Great White Spot. As water vapor and ammonia were pushed to the troposphere by vertical currents, some of the materials were dragged by eastern winds, creating the storm's characteristic "head" and straggling "tail," both of which are visible from Earth.
First author Agustin Sanchez-Lavega, a planetary scientist at the University of the Basque Country in Bilbao, Spain, and his colleagues were able to estimate that the storm's head, where most of the lightning was concentrated, extended about 160 miles below the cloud tops. Because the sun doesn't shine there, this suggests that the planet's internal heat helps the storms to form, the scientists wrote.
Great White Spots are 10 times larger than normal storms on Saturn and are about 10,000 times stronger than those on Earth. They occur seasonally due to changes in how much sunlight reaches Saturn. Scientists still don't fully understand the interplay between solar energy and Saturn's internal stores in generating these storms.Los Angeles Times...

“Every little piece of new knowledge is used by space agencies around the world to design new instrumentation to probe the unknown and unexplained. For example, who would have thought that the location of where coronal holes are on the Sun would be important for space weather effects?”
Asking questions in order to find answers and, of course, create a new path for new questions: This is the job of Bruce Tsurutani, a space weather scientist at NASA's Jet Propulsion Laboratory in Pasadena, Calif.
Tsurutani is in charge for the JPL to monitor solar activity and reveal the effects of wind and sun flares on Earth. Professor Tsurutani, awarded in 2009 the John A. Fleming Medal, and has spent much of his 40-year career on understanding the Sun-Earth connection and interplanetary physics.
He is the lead author of the paper “The solar and interplanetary causes of the recent minimum in geomagnetic activity,” co-authored by professors Walter Gonzalez and Ezequiel Echer.
In an exclusive interview interview, Professor Tsurutani describes what the solar minimum means for the planet and the solar system, how a magnetic storm can destroy or damage the human devices, and what are the studies run by NASA and U.S. governmental agencies in order to predict possible scenarios and the subsequent remedies.
Doctor Tsurutani, as the lead author of the paper “The solar and interplanetary causes of the recent minimum in geomagnetic activity,” can you explain what is the main or key result of your research?
The efforts of my two Brazilian colleagues, Profs. Echer and Gonzalez, and myself is to understand all facets of how the sun affects us here on Earth. We have previously studied two other phases of the 11 year solar (sunspot) cycle: solar maximum and the declining phase. Now we have starting to study the solar minimum phase.
Our main result was to explain how this record low geomagnetic activity at Earth occurred. We found that the coronal holes were small and placed at midlatitude locations on the sun and there were extremely low solar magnetic fields. The former is a poor location for solar wind impingement on the Earth (which is in the ecliptic plane) to occur. All of this was made possible by a very nice paper on coronal hole evolution written by G. de Toma. This stimulated our thinking.
What is the correlation between the solar wind and the 'solar minimum'?
During solar minimum (late 2008) the average solar wind speed detected at Earth was still high. Six months to a year later, the average speeds were much lower. So there was a delay of the solar wind speed decrease from solar minimum. However the speed of the solar wind coming from coronal holes on the sun did not change. It was just the location of the coronal holes that did. Does this happen every solar cycle? Probably so. But more research is needed to determine whether this hypothesis is correct or not. What in the interior of the Sun makes these coronal holes appear at middle latitudes? At this time we do not know.
What is the 'solar minimum' impact on our daily life and the impact on our space devices, like satellites?
Actually we now know that during solar minimum the environment is quite benign. There are no (or at least very few) solar flares or enhancements of the Van Allen radiation belts that could impact satellites. This would be a good time for space travel! There should not be any impacts to our daily lives (except beautiful auroras will be hard to find!).
How can solar wind affect the solar system mechanics?
The pressure from the solar wind is quite weak and has little effect on the solar system as it is today. However the distant past may be a different story.
The magnetic interactions are vital in our understanding of the universe; how does your research as a space weather specialist help to improve that knowledge?
Yes, space weather scientists now know that magnetic interactions is the most important mechanism for solar flares on the sun as well as energy transfer from the solar wind to the Earth’s magnetosphere. In 1859, R. Carrington made the first well-documented observation of a solar flare. He also made reference to a magnetic storm at Earth. From this, Profs. G. Lakhina and S. Alex of the Indian Institute of Geomagnetism, Prof. Gonzalez and I studied the solar and interplanetary causes of this storm — by far the largest ever recorded at Earth. We have never seen anything close to this intensity in our lifetimes. We did this as part of our solar maximum phase study. Magnetic interactions were presumed to take place both at the sun and at Earth.
Luckily, because this was such a huge event, scientists at the time took note and wrote papers on the fires set, electrical shocks that happened, and the brilliant auroral displays that occurred at Earth. This old information were used in our study. In 1859 the world was in a state of low technology in comparison to today. The “high tech” device at the time was the telegraph. NASA together with other U.S. governmental agencies are presently studying what would happen if a magnetic storm of Carrington intensity happened again today? Would power grids go out? Could satellites come down? Would the radiation from the solar flare and the Van Allen belts damage spaceborne electronics? The U.S. plans to be prepared in case something of this magnitude happens again.
Magnetic interactions are also important for laboratory plasma physics and astrophysics as well. Space weather scientists meet with plasma fusion physicists and astrophysicists on a regular basis to compare ideas and observations.
Have results of recent scientific investigations led to improvements that can be used in the near future on solar facilities?
Definitely. Every little piece of new knowledge is used by space agencies around the world to design new instrumentation to probe the unknown/unexplained. For example, who would have thought that the location of where coronal holes are on the Sun would be important for space weather effects? Now that it is known that this is important for geomagnetic activity at Earth, scientists will attempt to explain this.
What would happen if coronal holes disappeared altogether? Or the solar magnetic field became even weaker? Do we know enough about the interior of the Sun to be able to predict when this could happen, and for how long? This is the goal for all of us working in the field.“Every little piece of new knowledge is used by space agencies around the world... more

In April 1994, at a solo recital given by Mari Kimura in New York City, subharmonics were introduced to the musical community as a revolutionary bowing technique to extend the violin's range by a full octave below on the open G string without changing the tuning. Subharmonics require precise control of the bow pressure and speed, in order to freely utilize this extended bowing technique. Subharmonics can be used as a musical element for composers to explore additional possibilities for the violin and other string instruments. As the technique has grown significantly since the initial discovery more than 15 years ago, it was apparent that Subharmonics needed a closer look in the most controlled environment. .... http://www.makeahistory.com/index.php/album-rewievs/42971-mari-kimura-subharmonicsIn April 1994, at a solo recital given by Mari Kimura in New York City, subharmonics... more

(first published by Tom Spears, Ottawa Citizen June 6, 2011 2:05 AM)
A Canadian-led experiment has trapped mysterious antimatter in a container and held it for more than a quarter of an hour -probably longer -giving scientists the first chance to study the stuff.
The first antimatter ever created, in the mid-1990s, annihilated itself in the tiniest fraction of a second.
Now scientists are joking they have time for go for cof-fee while the antimatter waits for them.
"You can practically bottle the stuff," says Marcello Pavan of Triumf, Canada's national particle physics lab in Vancouver.
The work comes from CERN, the Swiss lab better known as the place where scientists smash protons against each other.
But unlike most global science projects where Canada plays a modest role, about one-third of the antimatter group is Canadian.
That includes its leader, Makoto Fujiwara of Triumf in Vancouver, who is thrilled at the new ability to bring an almost unknown material into the lab.
In normal matter an electron with a negative charge orbits a nucleus with a positive proton. In antimatter, a positively-charged version of the electron, called a positron, orbits a negative antiproton. It's famous in science fiction from Star Trek to Angels and Demons.
The Fujiwara team reports today in the journal Nature on 309 antiatoms it has created.
When antimatter touches matter, it annihilates itself in a burst of energy -a fact used over and over in science fiction. When the first real antimatter was manufactured, it would shoot along at close to light speed, bang into ordinary matter and obliterate itself.
Now it sits still, waiting for someone to do experiments on it.
Fujiwara hopes soon to shoot microwaves at it to see whether antihydrogen has the same spectrum as hydrogen. "It's almost like seeing whether they are the same colour," he says. Theory says yes. If they aren't right, "it will rewrite all the textbooks."
Later experiments may look at whether antimatter has gravity. Again, it should, but no one knows for sure.
"Canadians were actually the ones who pushed for this experiment, so we were in the forefront," Pavan said.
The team at CERN uses a magnet to keep the antimatter hanging in the centre of a vacuum. If they turn off the magnet, antimatter drifts over to the side of this "trap," touches ordinary matter, and is annihilated.
The team, called ALPHA, announced in November, 2010, that they had succeeded in storing antimatter atoms for the first time ever, hav-ing captured 38 atoms of antihydrogen and storing each for a sixth of a second. In the weeks following, ALPHA continued to collect anti-atoms and hold them for longer and longer times.
But why study it at all? "In the beginning of the universe, in the Big Bang, we believe there were equal amounts of matter and antimatter created," said Fujiwara.
Something happened to make the antimatter disappear, and now the hunt is on for an explanation.
Canadians in the team come from Triumf, University of British Columbia, Simon Fraser, York University and the University of Calgary.

“Our own Universe may be the interior of a black hole existing in another universe.” In a remarkable paper about the nature of space and the origin of time, Nikodem Poplawski, a physicist at Indiana University, suggests that a small change to the theory of gravity implies that our Universe inherited its arrow of time from the black hole in which it was born.
Poplawski says that the idea that black holes are the cosmic mothers of new universes is a natural consequence of a simple new assumption about the nature of spacetime. Poplawski points out that the standard derivation of general relativity takes no account of the intrinsic momentum of spin half particles. However there is another version of the theory, called the Einstein-Cartan-Kibble-Sciama theory of gravity, which does.
