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 November 27, 2014 at 6:47am: India is home to one of the highest proportions of threatened species in the world

Comment by Dr. Krishna Kumari Challa on November 27, 2014 at 6:36am: Asteroid impacts on Earth may give rise to rare, structurally bizarre diamonds on our planet, a new study suggests.

Scientists have settled a longstanding controversy over a purported rare form of diamond called lonsdaleite - formed by impact shock, but which lacks the three-dimensional regularity of ordinary diamond
A group of scientists has now shown that what has been called lonsdaleite is in fact a structurally disordered form of ordinary diamond.

"So-called lonsdaleite is actually the long-familiar cubic form of diamond, but it's full of defects," said Peter Nemeth, a former Arizona State University (ASU) visiting researcher.

These can occur, he said, due to shock metamorphism, plastic deformation or unequilibrated crystal growth

Scientists said that a large meteorite, called Canyon Diablo after the crater it formed on impact in northern Arizona, contained a new form of diamond with a hexagonal structure.

They described it as an impact-related mineral and called it lonsdaleite, after Dame Kathleen Lonsdale, a famous crystallographer.

Since then, "lonsdaleite" has been widely used by scientists as an indicator of ancient asteroidal impacts on Earth, including those linked to mass extinctions.

In addition, it has been thought to have mechanical properties superior to ordinary diamond, giving it high potential industrial significance.

All this focused much interest on the mineral, although pure crystals of it, even tiny ones, have never been found or synthesised.
Scientists re-examined Canyon Diablo diamonds and investigated laboratory samples prepared under conditions in which lonsdaleite has been reported.

Using the advanced electron microscopes, the team found, both in the Canyon Diablo and the synthetic samples, new types of diamond twins and nanometre-scale structural complexity. These give rise to features attributed to lonsdaleite

"Most crystals have regular repeating structures, much like the bricks in a well-built wall," said Peter Buseck, from the University of Bayreuth in Germany.

However, interruptions can occur in the regularity, and these are called defects.

"Defects are intermixed with the normal diamond structure, just as if the wall had an occasional half-brick or longer brick or row of bricks that's slightly displaced to one side or another," said Buseck.

The outcome of the new work is that so-called lonsdaleite is the same as the regular cubic form of diamond, but it has been subjected to shock or pressure that caused defects within the crystal structure.

The study was published in the journal Nature Communications.

Comment by Dr. Krishna Kumari Challa on November 26, 2014 at 9:20am: Hormone estrogen may shield the brain after an injury
Inflammation goes down when the sex hormone increases around an injury
Estrogen can protect the brain from harmful inflammation following traumatic injury, a new study in zebra finches suggests. Boosting levels of the sex hormone in the brain might help prevent the cell loss that occurs following damage from injuries such as stroke.

Estrogen levels quadrupled around the damaged area in both male and female zebra finches after researchers gave them experimental brain injuries, Colin Saldanha and colleagues at American University in Washington, D.C., reported November 17 at the annual meeting of the Society for Neuroscience. When the scientists prevented finch brains from making estrogen, inflammatory proteins at damaged sites increased.

The helpful estrogen didn’t come from gonads. It’s made within the brain by support cells called astrocytes close to the injury.

Injury inflames the brain. Initially, this inflammation recruits helpful cells to the damaged area and aids in recovery. But the long-term presence of inflammatory proteins can cause harm, killing off brain cells and reducing functions such as movement and memory. The researchers hope that by understanding how estrogen reduces inflammatory proteins, therapies might boost this natural estrogen production to keep harmful inflammation at bay.

Comment by Dr. Krishna Kumari Challa on November 26, 2014 at 8:03am: New light on heart disease:
Scientists now think that inflammation is a key factor in heart disease.

The older thinking was that plaque in coronary arteries caused heart attacks. Now the thinking is that it’s also due to some living tissue under plague that gets inflamed and that disrupts the plaque. We already knew statins ameliorate heart disease, and always thought it was through lipids, but here’s a new pathway.
And Statins May Protect People from Air Pollution
Statins, prescribed to lower cholesterol and reduce risks of heart attacks and strokes, seem to diminish inflammation that occurs after people breathe airborne particles.

The studies on these are still underway and we will report them when the results are published.

Comment by Dr. Krishna Kumari Challa on November 26, 2014 at 7:19am: Horizontal gene transfer: Antibiotic genes spread far and wide
The genes responsible for antibiotics can spread between the three domains of life—Archaea, Bacteria and Eukaryotes.

The genes for proteins with antibacterial properties are capable of spreading across stunning evolutionary distances (Metcalf et al., 2014). Their results suggest that our search for new antibiotics needs to be broadened if we are to take full advantage of the variety of antibacterial compounds that exist in nature.
Genes are able to move between organisms in a process known as horizontal gene transfer. This happens most frequently between individuals of the same, or closely-related species (Andam and Gogarten 2011) and is thought to be responsible for the spread of antibiotic resistance genes between bacteria. However, genes can also occasionally move between distantly-related individuals, including from one domain of life, such as Bacteria, to either Archaea or Eukaryotes (Lundin et al., 2010). Whether a gene is successfully transferred depends on a number of constraints. For instance, if the organisms inhabit different environments, there are fewer opportunities to transfer genes. Once transferred, a gene may not be compatible with the recipient, or may not provide it with an advantage. Despite these constraints, some genes have spread, via horizontal transfer, to all three domains of life, and such transfer events may have been extensive during evolution .

Comment by Dr. Krishna Kumari Challa on November 24, 2014 at 9:33am: IIT-M Joins CERN to Explore The Secrets of The Universe
Led by an expert who was part of the ATLAS experiment that helped find the Higgs Boson by the Large Hadron Collider at CERN, the Indian Institute of Technology - Madras has become a full member of a collaboration with the Geneva-based organisation in search of the structure of the universe.

While reputed institutions including TIFR, BARC and a few others have been partnering with CERN, IIT-M is the first IIT to come on board of the prestigious LHC experiment.

According to Prafulla Kumar Behera, an associate professor with the department of physics, this initiative will help the institute strengthen its capabilities in fundamental research. "CERN is home to a lot of innovations, including the world wide web. This collaboration is like a bridge that would connect us to the highest level of scientific research while offering them our talent and expertise," Behera told The New Indian Express.

Besides him, another faculty, James Libby, and two PhD scholars have come on board on the CMS collaboration.
