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 April 10, 2014 at 6:41am: Scientists in Taiwan has uncovered how a viral DNA polymerase breaks the golden Watson-Crick rule.
Replication of DNA occurs in all living organisms and forms the basis of biological inheritance. DNA is formed and replicated through the pairing of the four nucleotides, adenine (A), thymine (T), cytosine (C) and guanine (G) in a specific pattern: A pairs with T and C pairs with G. This is known as the Watson-Crick base-pairing rule. The synthesis of new strands of DNA is facilitated by enzymes called DNA polymerases.

Scientists have long been fascinated by the fidelity of the DNA polymerase reaction — the way in which the pairing rule is invariably followed. However, in recent years scientists have discovered polymerases that do not follow the Watson-Crick rule, and have sought explanations for how these enzymes function.

Recently published in the chemistry periodical Journal of American Chemistry, Tsai’s research investigated a DNA polymerase from the African swine fever virus named Pol X. Pol X is unusual because it can get G to pair with itself, on top of following the Watson-Crick rule.
In conventional DNA polymerization, the enzyme firsts binds to the DNA, and only subsequently the free nucleotides. This allows the DNA sequence to determine which nucleotide binds, restricting the binding to nucleotides complementary to the DNA template. The team found, however, that Pol X is able to bind nucleotides in the absence of DNA.

“Kinetic studies suggested that Pol X does not follow the established mechanistic paradigm that DNA polymerases bind DNA before binding to a nucleotide,” Tsai explained.

The results demonstrate the first solution structural view of DNA polymerase catalysis and a novel mechanism for non-Watson-Crick incorporation by a low-fidelity DNA polymerase.

Comment by Dr. Krishna Kumari Challa on April 9, 2014 at 7:05am: A speedy particle from beyond the solar system is the new record holder for the highest-energy neutrino ever detected, researchers from the IceCube experiment announced April 7 at a meeting of the American Physical Society.

Buried under an Antarctic glacier, IceCube consists of thousands of detectors looking for flashes of light triggered when neutrinos, particles that barely interact with anything as they cruise the cosmos, collide with the ice. Incorporating a year’s worth of new data, researchers announced that IceCube detected nine additional high-energy neutrinos for a total of 37.

One of the nine neutrinos struck the ice with a record 2 million billion electron volts of energy. Continuing the tradition of naming neutrinos after Muppets, the scientists named it Big Bird.

Comment by Dr. Krishna Kumari Challa on April 9, 2014 at 7:03am: A study found that up to half of 2 year olds were picky eaters. Food choosiness isn’t just a way for a kid to drive a parent mad. Pickiness actually makes sense: When kids are bombarded with new and unusual foods, sticking with safe, familiar choices is a good way to avoid eating something dangerous.
''Prevalence of picky eaters among infants and toddlers and their caregivers’ decisions about offering a new food''
http://www.journals.elsevierhealth.com/periodicals/yjada/article/S0...
Taste preferences start in the womb. Fetuses slurp up amniotic fluid, seasoned with whatever mom just ate. (You’re welcome for the seasoned amniotic fluid imagery.) These flavors, such as carrots or garlic, tap into the fetus’s taste system, which begins to form in the first trimester. The more exposure to a certain taste, the more a baby is to eventually like it. Babies whose mothers drank a lot of carrot juice while pregnant and breastfeeding preferred carrot-flavored cereal, for instance.
Familiarity breeds yum, in this case. And I was amazed when I saw just what familiarity means to young kids. Some recent work suggests that to get kids used to a certain flavor, that food should be offered and tasted anywhere from six to 14 times. That’s a whole lot of tasting. And lots of parents don’t have that kind of patience. Most parents reported giving their kids a new food three to five times before giving up. Only 6 to 9 percent of parents kept offering a new food six to 10 times.

This kind of intense exposure can transform a reviled food into a familiar one, making the kid more likely to eat it. One study had parents give their child a tiny taste of one of six raw vegetables (carrots, cucumbers, tomatoes, celery, green peppers or red peppers) every day for 14 days. After this intense tasting exposure, kids were more likely to eat the veggie, the researchers found.

Comment by Dr. Krishna Kumari Challa on April 9, 2014 at 5:59am: Stress alters children's genomes

Poverty and unstable family environments shorten chromosome-protecting telomeres in nine-year-olds.
Growing up in a stressful social environment leaves lasting marks on young chromosomes, a study of African American boys has revealed. Telomeres, repetitive DNA sequences that protect the ends of chromosomes from fraying over time, are shorter in children from poor and unstable homes than in children from more nurturing families.

Comment by Dr. Krishna Kumari Challa on April 9, 2014 at 5:52am: After more than six decades, estimates of global species richness have failed to converge, remain highly uncertain, and in many cases, are logically inconsistent. Convergence in these estimates could be accelerated by adaptive learning methods where the estimation of uncertainty is prioritised and used to guide future research.

Comment by Dr. Krishna Kumari Challa on April 9, 2014 at 5:50am: Absence (of Weight) Makes the Heart Grow Rounder
After prolonged periods in microgravity, astronauts' hearts became more spherical, according to scans done on the International Space Station.
When astronauts float weightless in space, their muscles don't need to work as hard as on Earth. Muscles therefore atrophy during a long mission, which can cause trouble when space travelers return home. But what happens to that most vital of muscles, the heart?

To find out, 12 astronauts learned how to do ultrasound scans of their hearts. Then they recorded the organ's shape before, during and after a stint on the International Space Station. The scans showed that while in microgravity the astronauts' hearts deformed into more spherical shapes. Back on Earth, they stretched back into their usual elongated forms. The work was presented at the annual scientific session of the American College of Cardiology. [Chris May et al, Affect of Microgravity on Cardiac Shape: Comparison of Pre- and In-Flight Data to Mathematical Modeling]

Knowing how weightlessness changes the heart could help mission planners prevent long-term damage to astronauts’ cardiovascular systems due to long space voyages. Astronauts on the space station already perform specific exercises to keep their weight-bearing muscles toned. Similarly well-designed workouts might keep hearts both in shape—and in the right shape.
