NASA’S Hubble telescope captured an image of a baby star buried in interstellar gas and dust with massive jets emitting from it that seem to resemble a double-bladed lightsaber from the new film “Star Wars: The Force Awakens.” Dr.
A team of researchers from the University of New South Wales (UNSW) have discovered a rocky planet that sits perfectly in the habitable "Goldilocks" zone of a Sun-like star located just 14 light years away from Earth.
Just last month, astronomers from the Edinburgh University had found a planet-like object without any parent star about 75 light years away from Earth The new planet discovered, named Wolf 1061c, is about four times the size of Earth and is the nearest potentially habitable world, according to scientists. It has a rocky, solid surface which is usually considered to be necessary to support alien life. Presence of a planet in the "Goldilocks zone" makes the planet neither too hot nor too cold, meaning the planet could support life. Wolf 1061 lies in Ophiucus constellation and is the 35th closest star to Earth.
Lead researcher Dr Duncan Wright revealed in a statement that their team has actually found three planets revolving around a red dwarf star. These planets are of "low enough mass" and have a solid surface. Of these three planets, one is located very close to the star, while the other one lies too far out. The middle of these three planets, Wolf 1061c, "sits within the 'Goldilocks' zone where it might be possible for liquid water - and maybe even life - to exist."
"A novel method for "plucking" individual particles of light out of a laser pulse could lead to major breakthroughs in quantum computing, researchers say.
Using a combination of supercooled atoms and cutting-edge optical technology, physicists from the Weizmann Institute of Science in Israel were able to extract a single photon from a beam of light.
Individual photons are of great interest to physicists because they are governed by the laws of quantum mechanics rather than the rules of classical physics (which normally apply to light). Many scientists also see photons as a promising candidate to carry information in future quantum computing systems. [Wacky Physics: The Coolest Little Particles in Nature]
India hopes to build one of the world's largest basic science laboratories to understand the very fundamental nature of the universe. The Neutrino Observatory (INO), a project worth Rs 1,500 crore is to come up deep inside a cavern in Tamil Nadu.
Tantalizing results from upgraded collider will be followed up within a year.
The two experiments that discovered the Higgs boson in 2012 have sensed an intriguing — if very preliminary — whiff of a possible new elementary particle. Both collaborations announced their observations on 15 December, as they released their first significant results since a major upgrade of the Large Hadron Collider (LHC) outside Geneva, Switzerland, was completed earlier this year.
The results largely match a rumour that has been circulating on social media and blogs for several days: that both the CMS and ATLAS detectors at the LHC have seen an unexpected excess of pairs of photons, together carrying around 750 gigaelectronvolts (GeV) of energy, in the debris of their proton–proton collisions. This could be a tell-tale sign of a new particle — also a boson, but not necessarily similar to the Higgs — decaying into two photons of equal mass. If so, the particle would be about four times more massive than the next heaviest particle discovered so far, the top quark, and six times more massive than the Higgs.
In their talks at CERN — the laboratory that hosts the LHC — the speakers for the two experiments took turns in surveying the results of the higher-energy, 'run 2' of experiments, which began in June and was suspended in early November. Both speakers left the results on photon pairs for the end of their talks.
In both cases, the statistical significances were very low. Marumi Kado of the Linear Accelerator Laboratory at the University of Paris-Sud said that his experiment, ATLAS, had detected about 40 more pairs of photons than would have been expected from the predictions of the standard model of particle physics. Jim Olsen of Princeton University in New Jersey reported that CMS saw merely ten. Neither team would have mentioned the excesses had the other experiment had not seen an almost identical hint. “It is a little intriguing,” says ATLAS spokesperson Dave Charlton of the University of Birmingham, UK. “But it can happen by coincidence.”

A recently discovered set of original Nikola Tesla drawings reveal a map to multiplication that contains all numbers in a simple to use system.
The drawings were discovered at an antique shop in central Phoenix Arizona by local artist, Abe Zucca. They are believed to have been created during the last years of Tesla’s Free Energy lab, Wardenclyffe.
Tesla is known for the quote “If you only knew the magnificence of the 3, 6 and 9, then you would have the key to the universe.” It turns out that when the device is examined, the digital roots of the numbers in positions 3, 6, 9, and 12 constantly repeat the same sequence 3, 6, 9! Is this what Tesla was referring too? The self-organization of numbers and their digital roots?
Its hard to say, but Grether seems to think so. “This breakthrough is phenomenal. If we could get students all over the globe to use this technique, to play with it, and help figure out how to use it, we could overcome our cultural aversion to Mathematics. Instead of memorizing the multiplication table, we could learn the positions of numbers and have a better understanding of how they work.”
For the first time, researchers have demonstrated the precise requirements for secure quantum teleportation – and it involves a phenomenon known 'quantum steering', first proposed by Albert Einstein and Erwin Schrödinger.
Before you get too excited, no, this doesn't mean we can now teleport humans like they do on Star Trek. Instead, this research will allow people to use quantum entanglement to send information across large distances without anyone else being able to eavesdrop. Which is almost as cool, because this is how we'll form the un-hackable communication networks of the future.
Quantum teleportation isn't new in itself. Researchers have already had a lot of success quantum teleporting information over 100 km of fiber. But there's a slight issue – the quantum message was getting to the other end kinda incoherent, and scientists haven't exactly known what to do to prevent that from happening, until now.
"Teleportation works like a sophisticated fax machine, where a quantum state is transported from one location to another," said one of the researchers, Margaret Reid, from Swinburne University of Technology in Australia. "Let’s say 'Alice' begins the process by performing operations on the quantum state – something that encodes the state of a system – at her station. Based on the outcomes of her operations, she communicates (by telephone or public Internet) to 'Bob' at a distant location, who is then able to create a replica of the quantum state," she explains.
"The problem is that unless special requirements are satisfied, quantum mechanics demands that the state at Bob’s end will be 'fuzzed up'." The researchers have now shown that to avoid this, Alice and Bob (or anyone else who wants to send an entangled message) need to use a special form of quantum entanglement known as 'Einstein-Podolsky-Rosen steering'.
"Only then can the quality of the transported state be perfect," said Reid. "The beauty is that quantum mechanics guarantees that a perfect state can only be transported to one receiver. Any second 'eavesdropper' will get a fuzzy version." Basically, in this quantum steering state, the measurement of one entangled particle can have an immediate 'steering' effect on the state of another distant particle.
The researchers will continue to investigate this phenomenon to figure out how it can be used to more reliably communicate using quantum entanglement.
