We scan the digital environment to examine the leading trends in emerging technology today to know more about future.



We have added a few indices around the site. Though we look to the future, we need to keep an eye on the present as well:

Physics: Not our normal presentation. However, this composition by Melodysheep on the Quantum world as part of it`s Symphony of Science Series is so catchy that it will remain with you all day.

Hottest Particle Soup May Reveal Secrets of Primordial Universe

Above a critical temperature, protons and neutrons and other forms of hadronic matter “melt” into a hot, dense soup of free quarks and gluons (background), the quark-gluon plasma.

A soup of ultra-hot elementary particles could be the key to understanding what the universe was like just after its formation, scientists say.

Over the past few years, physicists have created this soup inside two of the world’s most powerful particle accelerators — the Large Hadron Collider (LHC) in Switzerland and the Relativistic Heavy Ion Collider (RHIC) in New York — by smashing particles together at superfast speeds.

When two particles collide, they explode into pure energy powerful enough to melt down atoms and break apart protons and neutrons (the building blocks of atomic nuclei) into their constituent quarks and gluons. Protons and neutrons contain three quarks each, and gluons are the mass-less glue that holds the quarks together.

The result is a plasma scientists call an “almost-perfect liquid,” with almost zero friction.

Hotter than the sun

At temperatures between 7 trillion and 10 trillion degrees Fahrenheit (4 trillion and 6 trillion degrees Celsius), this “quark-gluon plasma” is the hottest thing ever created on Earth, and is about 100,000 times hotter than the center of the sun.

“We now have created matter in a unique state, composed of quarks and gluons that have been liberated from inside protons and neutrons,” said Steven Vigdor, a physicist at Brookhaven National Laboratory, which hosts the RHIC. This bizarre state of matter is thought to closely resemble the form of matter in the universe just a few fractions of a second after it was born in the Big Bang about 13.7 billion years ago.

“Many critical features of the universe were established at those very early moments in the infancy of the universe,” Vigdor said today (Aug. 13) at the Quark Matter 2012 particle physicists conference in Washington, D.C.

Soon after this phase of the universe, quarks and gluons would have combined to form protons and neutrons, which would have grouped with electrons a while later to form atoms. These eventually built the galaxies, stars and planets that we know today.

Record-Breaking Laser Hits 500 Trillion Watts

Laser physicists at the Lawrence Livermore National Laboratory have broken the record for the highest-power laser shot with a collection of beams delivering more than 500 trillion watts of peak power.

The National Ignition Facility fired 192 beams at the same time, delivering 1.85 megajoules of ultraviolet laser light to a target a mere two millimeters in diameter.

To put those numbers into perspective, the 500 terawatt figure is 12,500 times greater than the demand for electricity in 2006 in Britain, which averaged out at 40 gigawatts.

“For scientists across the nation and the world who, like ourselves, are actively pursuing fundamental science under extreme conditions and the goal of laboratory fusion ignition, this is a remarkable and exciting achievement,” said Richard Petrasso, senior research scientist and division head of high energy density physics at the Massachusetts Institute of Technology in a press release. “The 500 TW shot is an extraordinary accomplishment by the NIF Team, creating unprecedented conditions in the laboratory that hitherto only existed deep in stellar interiors,”

The National Ignition Facility is the world’s foremost laser research establishment, producing lasers than can regularly carry more than 100 times the energy of any other laser. The 500 terawatt firing hits a milestone set in the late 90s when the facility was being planned, and takes researchers a step closer to the goal of igniting hydrogen fusion.

“NIF is becoming everything scientists planned when it was conceived over two decades ago,” NIF director Edward Moses said in the release. “It is fully operational, and scientists are taking important steps toward achieving ignition and providing experimental access to user communities for national security, basic science and the quest for clean fusion energy.”

Higgs Boson particle found (or something at least). So what is it? Watch the clip to find out:

Physicists Have Found the Higgs Boson

At a meeting held at CERN this morning, scientists presented the latest results from the search for the long-sought Higgs particle. After 30 years of research and $9 billion of investment, they’ve changed the face of physics forever: they’ve found the Higgs boson.

One of the biggest debuts in the science world could happen in a matter of weeks: The Higgs boson may finally, really have been discovered!

The antimatter version of the hydrogen atom - antihydrogen - could soon finally give up its secrets.

Scientists expect that antihydrogen will have exactly the same properties as hydrogen; but after 80 years, the test is only just becoming possible.

A report in Nature has shown the first “spectra” of trapped antihydrogen, showing the energy required to change the spins of its positrons.

‘Faster than light’ neutrinos may have been a technical glitch.

Last year scientists at CERN made news claiming to have found neutrinos travelling at superluminal speeds, arriving 60 nanoseconds earlier than expected when sent between two laboratories.

Now a source close to the experiment has claimed that the result was because of faulty wiring.

The report in Science Insider said the “60 nanoseconds discrepancy appears to come from a bad connection between a fiber optic cable that connects to the GPS receiver used to correct the timing of the neutrinos’ flight and an electronic card in a computer. “

“After tightening the connection and then measuring the time it takes data to travel the length of the fiber, researchers found that the data arrive 60 nanoseconds earlier than assumed,” it added.

“Since this time is subtracted from the overall time of flight, it appears to explain the early arrival of the neutrinos. New data, however, will be needed to confirm this hypothesis.”
