WE LOVE SCIENCE HERE BECAUSE IT IS A MANY SPLENDOURED THING

THIS IS A WAR ZONE WHERE SCIENCE FIGHTS WITH NONSENSE AND WINS

“The greatest enemy of knowledge is not ignorance, it is the illusion of knowledge.”

"Being a scientist is a state of mind, not a profession!"

"Science, when it's done right, can yield amazing things".

The Reach of Scientific Research From Labs to Laymen

The aim of science is not only to open a door to infinite knowledge and wisdom but to set a limit to infinite error.

"Knowledge is a Superpower but the irony is you cannot get enough of it with ever increasing data base unless you try to keep up with it constantly and in the right way!" The best education comes from learning from people who know what they are exactly talking about.

Science is this glorious adventure into the unknown, the opportunity to discover things that nobody knew before. And that’s just an experience that’s not to be missed. But it’s also a motivated effort to try to help humankind. And maybe that’s just by increasing human knowledge—because that’s a way to make us a nobler species.

If you are scientifically literate the world looks very different to you.

We do science and science communication not because they are easy but because they are difficult!

“Science is not a subject you studied in school. It’s life. We 're brought into existence by it!"

Comment by Dr. Krishna Kumari Challa on December 18, 2014 at 8:04am: Quantum-secure authentication of a physical unclonable key

Credit cards and ID cards which could never be hacked? That's the promise of quantum cryptography, which harnesses peculiar properties of subatomic particles to thwart data thieves.

Now a team of Dutch researchers says we're closer to making such technology a practical reality.

Publishing in the current issue of Optica, scientists at the University of Twente and Eindhoven University of Technology describe what they call quantum-secure authentication (QSA) of a "classical multiple-scattering key."
Authentication of persons and objects is a crucial aspect of security. We experimentally demonstrate quantum-secure authentication (QSA) of a classical multiple-scattering key. The key is authenticated by illuminating it with a light pulse containing fewer photons than spatial degrees of freedom and verifying the spatial shape of the reflected light. Quantum-physical principles forbid an attacker to fully characterize the incident light pulse. Therefore, he cannot emulate the key by digitally constructing the expected optical response, even if all information about the key is publicly known. QSA uses a key that cannot be copied due to technological limitations and is quantum-secure against digital emulation. Moreover, QSA does not depend on secrecy of stored data, does not depend on unproven mathematical assumptions, and is straightforward to implement with current technology.

Comment by Dr. Krishna Kumari Challa on December 18, 2014 at 7:44am: Low glycemic index foods do not reduce risk factors for cardiovascular disease and diabetes
In a 5-week controlled feeding study, diets with low glycemic index of dietary carbohydrate, compared with high glycemic index of dietary carbohydrate, did not result in improvements in insulin sensitivity, lipid levels, or systolic blood pressure. In the context of an overall DASH-type diet, using glycemic index to select specific foods may not improve cardiovascular risk factors or insulin resistance.

Comment by Dr. Krishna Kumari Challa on December 17, 2014 at 8:24am: Messages received from Voyager 1, the Nasa spacecraft travelling 19.5 billion kms away from Earth, show that it is continuing to experience a "tsunami wave" as it penetrates the interstellar medium beyond the solar System.

The spacecraft launched in 1977 is the farthest a man made object has gone from Earth ever. So far, signals from its instruments travelling at the speed of light take 36 hours and 14 minutes to reach Earth.

"Most people would have thought the interstellar medium would have been smooth and quiet. But these shock waves seem to be more common than we thought," said Don Gurnett, professor of physics at the University of Iowa in Iowa City. Gurnett presented the new data Monday, Dec. 15 at the American Geophysical Union meeting in San Francisco.

A "tsunami wave" occurs when the sun emits a coronal mass ejection, throwing out a magnetic cloud of plasma from its surface. This generates a wave of pressure. When the wave runs into the interstellar plasma -- the charged particles found in the space between the stars -- a shock wave results that perturbs the plasma.

"The tsunami causes the ionized gas that is out there to resonate -- "sing" or vibrate like a bell," said Ed Stone, project scientist for the Voyager mission based at California Institute of Technology in Pasadena.

Comment by Dr. Krishna Kumari Challa on December 17, 2014 at 8:07am: Celiac disease: Immune responses to wheat go beyond gluten

The immune response to gluten in wheat and related cereals in celiac disease is well established but whether other cereal components also induce an immune response is less well understood. A new paper published online in the Journal of Proteome Research suggests that non-gluten proteins in wheat do trigger an immune reaction and could potentially contribute to celiac disease.

Comment by Dr. Krishna Kumari Challa on December 17, 2014 at 7:28am: Humans First Built Fire 350000 Years Ago
New evidence from an Israeli cave indicates that humans first built fires around 350,000 years ago, according to a new study.

An international team led by Ron Shimelmitz from the University of Haifa examined flint debris and tools discovered in the Tabun Cave in northern Israel. While the study finds archaeological evidence of fire dating back to a million years ago, researchers focus on humans' habitual use of fire.
http://www.academia.edu/8858729/Fire_at_will_The_emergence_of_habit...

The use of fire is central to human survival and to the processes of becoming human. The earliest evi-dence for hominin use of fire dates to more than a million years ago. However, only when fire use became a regular part of human behavioral adaptations could its benefits be fully realized and its evolutionaryconsequences fully expressed. It remains an open question when the use of

fire shifted from occasional and opportunistic to habitual and planned. Understanding the time frame of this 'technological mutation' will help explain aspects of our anatomical evolution and encephalization over the last million years. It will also provide an important perspective on hominin dispersals out of Africa and the colonization of temperate environments, as well as the origins of social developments such as the formation of provi-sioned base camps. Frequencies of burnt flints from a 16-m-deep sequence of archaeological deposits atTabun Cave, Israel, together with data from the broader Levantine archaeological record, demonstratethat regular or habitual fire use developed in the region between 350,000-320,000 years ago. While hominins may have used

fire occasionally, perhaps opportunistically, for some million years, the researchers argue in the paper that it only became a consistent element in behaviuoral adaptations during the second part of the Middle Pleistocene.

Comment by Dr. Krishna Kumari Challa on December 17, 2014 at 7:12am: Merging data on high-energy bursts seen on Earth by NASA's Fermi Gamma-ray Space Telescope with data from ground-based radar and lightning detectors, scientists have completed the most detailed analysis to date of the types of thunderstorms producing terrestrial gamma-ray flashes, or TGFs.
TGFs occur unpredictably and fleetingly, with durations less than a thousandth of a second, and remain poorly understood. Yet the gamma rays they produce rank among the highest-energy light naturally produced on Earth.
Earlier Fermi studies helped uncover lightning-like radio signals emitted by TGFs. This made it possible to use ground-based lightning location networks to pin down storms producing the flashes, opening the door to a deeper understanding of the meteorology powering these extreme events.
Scientists gathered a sample of nearly 900 Fermi TGFs accurately located by ground networks, which can pinpoint the location of lightning discharges -- and the corresponding signals from TGFs -- to within 6 miles (10 km) anywhere on the globe. From this group, they identified 24 TGFs that occurred within areas covered by Next Generation Weather Radar (NEXRAD) sites.
The researchers found that even weak and marginally electrified storms are capable of producing TGFs.
The new study also confirms previous findings indicating that TGFs tend to occur near the highest parts of a thunderstorm, between about 7 and 9 miles (11 to 14 kilometers) high. However, TGFs associated with lightning at lower altitudes would be so weakened by traveling a longer path through the atmosphere that Fermi couldn't detect them. If true, the estimated number of 1,100 TGFs occurring each day may be much larger than previously thought.

Comment by Dr. Krishna Kumari Challa on December 17, 2014 at 6:44am: Reproducibility project: cancer biology: Time to do something about reproducibility
Individual scientists, scientific communities and scientific journals can do more to assess the publication of irreproducible results, to promote good science, and to increase the efficiency with which the scientific community self-corrects.
