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 August 2, 2014 at 10:48am: Elaborate visual and acoustic signals evolve independently in a large, phenotypically diverse radiation of songbirds

Abstract of a study:

The concept of a macroevolutionary trade-off among sexual signals has a storied history in evolutionary biology. Theory predicts that if multiple sexual signals are costly for males to produce or maintain and females prefer a single, sexually selected trait, then an inverse correlation between sexual signal elaborations is expected among species. However, empirical evidence for what has been termed the ‘transfer hypothesis’ is mixed, which may reflect different selective pressures among lineages, evolutionary covariates or methodological differences among studies. Here, we examine interspecific correlations between song and plumage elaboration in a phenotypically diverse, widespread radiation of songbirds, the tanagers. The tanagers (Thraupidae) are the largest family of songbirds, representing nearly 10% of all songbirds. We assess variation in song and plumage elaboration across 301 species, representing the largest scale comparative study of multimodal sexual signalling to date. The researchers consider whether evolutionary covariates, including habitat, structural and carotenoid-based coloration, and subfamily groupings influence the relationship between song and plumage elaboration. They find that song and plumage elaboration are uncorrelated when considering all tanagers, although the relationship between song and plumage complexity varies among subfamilies. Taken together, they find that elaborate visual and vocal sexual signals evolve independently among tanagers.

Comment by Dr. Krishna Kumari Challa on August 2, 2014 at 10:47am: Life-Threatening Events During Endurance Sports : Is Heat Stroke More Prevalent Than Arrhythmic Death?

A study was conducted

Overall, 137,580 runners participated in long distance races during the study period. There were only 2 serious cardiac events (1 myocardial infarction and 1 hypotensive supraventricular tachyarrhythmia), neither of which were fatal or life threatening. In contrast, there were 21 serious cases of heat stroke, including 2 that were fatal and 12 that were life threatening. One of the heat stroke fatalities presented with cardiac arrest without previous warning.

In the study cohort of athletes participating in endurance sports, for every serious cardiac adverse event, there were 10 serious events related to heat stroke. One of the heat stroke–related fatalities presented with unheralded cardiac arrest. The results put in a different perspective the ongoing debate about the role of pre-participation electrocardiographic screening for the prevention of sudden death in athletes.

Comment by Dr. Krishna Kumari Challa on August 1, 2014 at 9:47am: Pune's landslide : what the environmentalists say:
Environmentalists have expressed concern over the uncontrolled deforestation of private forests in southern Maharashtra. They said the trend of hilltop farming, developing farm houses, roads, installing wind mills and mining is causing deforestation in Kolhapur, Sangli and Satara districts.
Experts have also said that razing tree cover in the Sahyadri mountain ranges will invite landslides in southern Maharashtra.
A disaster like the massive landslide that buried Malin village in Pune district on Wednesday is waiting to happen in the region if forests are repeatedly encroached up, warned people who have been working towards protecting the environment for more than two decades.

landslide in Maharashtra's Ambegaon and last year's flash floods and landslides in Uttarakhand may in reality indicate a trend likely to recur across the country - as over the years huge tracts of 'dense' forests having the capacity to hold soil and protect slopes have been lost.

Most of the increase in forest cover has been in 'open forest area'. This is non-dense forest, barely enough to be considered a green patch that may reap ecological benefits decades later. Environmentalists call it a recipe for disaster as India keeps clearing 'dense' forest cover having the capacity to hold soil/ protect the slopes for various projects.

Comment by Dr. Krishna Kumari Challa on August 1, 2014 at 9:28am: Vision-correcting display
UC Berkeley computer and vision scientists are developing computer algorithms to compensate for an individual's visual impairment, and creating vision-correcting displays that enable users to see text and images clearly without wearing eyeglasses or contact lenses. The technology could potentially help hundreds of millions of people who currently need corrective lenses to use their smartphones, tablets and computers. One common problem, for example, is presbyopia, a type of farsightedness in which the ability to focus on nearby objects is gradually diminished as the aging eyes' lenses lose elasticity.

More importantly, the displays could one day aid people with more complex visual problems, known as high order aberrations, which cannot be corrected by eyeglasses, said Brian Barsky, UC Berkeley professor of computer science and vision science, and affiliate professor of optometry.

Comment by Dr. Krishna Kumari Challa on August 1, 2014 at 6:07am: A virus that lives in the human gut has just been discovered, and to the surprise of scientists, it can be found in about half the world's population, according to a new study.
The new virus, which the researchers have named crAssphage, is a type of virus known as a bacteriophage that infects bacteria.
While it's not yet clear exactly what the virus does, scientists are eager to find out whether it promotes health or influences susceptibility to certain conditions.
The study is published on July 24, 2014 in the journal Nature Communications.

Comment by Dr. Krishna Kumari Challa on July 31, 2014 at 6:04am: Bio-degradable plastic from rice starch:

Researchers in Finland have transformed rice starch into a temporally stable, optically transpa... with a high degree of mechanical strength and good thermal resistance. This important step towards bioplastics made from simple and sustainable resources has potential applications in food packaging and biomedical materials.

Comment by Dr. Krishna Kumari Challa on July 30, 2014 at 11:01am: Scientists have developed nanomaterials capable of simultaneous photodynamic therapy and photothermal therapy to treat tumors. When illuminated under specific wavelengths, these nanomaterials are able to produce reactive oxygen species and heat at the same time, killing tumor cells. This research has been published in the journal Advanced Materials.
http://onlinelibrary.wiley.com/enhanced/doi/10.1002/adma.201400703/
Gold nanoechinus can sensitize formation of singlet oxygen in the first and the second near-infra red (NIR) biological windows and exert in vivo dual modal photodynamic (PDT) and photothermal therapeutic effects (PDT) to destruct the tumors completely. This is the first literature example of the dual modal nanomaterial-mediated photodynamic and photothermal therapy (NmPDT & NmPTT) induced destruction of tumors in NIR window II.

Comment by Dr. Krishna Kumari Challa on July 30, 2014 at 10:23am: New blood test could detect cancer early

British scientists claim they’ve developed a simple blood test that could detect cancer and prompt early, life-saving measures.

The tests are aimed at analyzing white blood cell which are “under stress” when there’s cancer or precancerous growth in the body, researchers wrote in the journal of the Federation of American Societies for Experimental Biology.

“We know that they are under stress when they are fighting cancer or other diseases, so I wondered whether anything measurable could be seen if we put them under further stress with UVA light,” according to lead researcher Diana Anderson, from the University of Bradford’s School of Life Sciences.

“We found that people with cancer have DNA which is more easily damaged by ultraviolet light than other people.”

The Lymphocyte Genome Sensitivity (LGS) tests looked at blood samples from 208 people — including healthy university staff and students and patients at the Bradford Royal Infirmary.

UVA light was shined on all blood samples, and DNA damage perfectly correlated to conditions of each subject, according to researchers.

The 58 subjects with the most damaged DNA samples turned out to be cancer patients, while 56 with precancerous conditions showed moderate DNA damage, researchers said.

The 94 cancer-free samples similarly showed minimal DNA damage after being exposed to UVA light, according to findings.
