         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!"

A study, published in the journal Science recently, used a mathematical model to simulate the changes that take place during desertification and matched the theoretical results with real observations in termite-inhabited regions on the edge of deserts. And it was found that mounds of soil made by termites when they build their high-rise nests have been found to hold back the encroachment of deserts in dry, savannah grasslands threatened with desertification.
The ground surrounding termite mounds store nutrients and water better than it otherwise would, which allows plants to grow and flourish while the empty, termite-free land further away dries out, the researchers said.

A study discovered that the myriad of tiny underground tunnels created by termites when they build their multi-storey nests allow rainwater to penetrate the soil which helps to slow the spread of deserts in the dry grasslands of Africa, South America and Asia.

“The rain is the same everywhere, but because termites allow water to penetrate the soil better, the plants grow on or near the mounds as if there were more rain.
So, termites stop desertification! Termite mounds are a boon to ecology!

Unconscious thought not so smart after all

Study on decision-making stokes controversy over power of distracted mind.
If you have to make a complex decision, will you do a better job if you absorb yourself in, say, a crossword puzzle instead of ruminating about your options? The idea that unconscious thought is sometimes more powerful than conscious thought is attractive, and echoes ideas popularized by books such as writer Malcolm Gladwell’s best-selling Blink.

Science pours in from Rosetta comet mission
GM microbes created that can’t escape the lab
Crunch time for pet theory on dark matter

But within the scientific community, ‘unconscious-thought advantage’ (UTA) has been controversial. Now Dutch psychologists have carried out the most rigorous study yet of UTA — and find no evidence for it.

Their conclusion, published this week in Judgement and Decision Making, is based on a large experiment that they designed to provide the best chance of capturing the effect should it exist, along with a sophisticated statistical analysis of previously published data.

Scientists unlock one of Nature’s best-kept secrets: How plants make natural medicines
Scientists at the John Innes Centre have discovered how plants make valuable natural products we rely on today for use as medicines, flavours and scents. This discovery has the potential to pave the way for the creation of entirely new drugs, flavourings and cosmetic ingredients.

Most plant-derived drugs, scents and flavours contain hydrocarbon rings in their structures – and until now exactly how Nature makes them has remained a mystery.

Recent work by a team of scientists at the John Innes Centre, led by Dr Paul O'Maille, resulted in the discovery of the origins of these cyclic or ring forming reactions in plants – which yield medicines like artemisinin: the most potent antimalarial drug, as well as flavours such as ginger and scents like bergamot.

The key to their success was breeding enzymes, the protein machinery that catalyses chemical reactions in plants. In particular they focused on enzymes that catalysed the formation of terpenes: the most diverse class of predominantly cyclic (ring-containing) natural products. By breeding a pair of enzymes, one that makes linear, less complex terpenes with one that makes cyclic terpenes, Dr Melissa Salmon, the lead author on the paper, was able to localize the trait of cyclization in the protein structure.
This research was published recently in Nature Communications.

Mercury levels in Hawaiian Yellowfin tuna – known as ahi on the plate – are on the rise, scientists report February 2 in Environmental Toxicology and Chemistry.

Data collected in 1998 and 2008 showed that mercury levels increased at a rate of about 3.8 percent per year, the researchers say. A tuna about 75 kilograms in size might have had about 0.4 parts per million of mercury in its body in 1998. In 2008, the same-sized fish would have had around 0.6 parts per million.

The tuna’s increase in toxic baggage mirrors increasing levels of mercury pollution from human activities, such as burning coal in power plants and mining.

Is there a The Best Position For Birth?
The time honored tradition of elevating women 15 degrees during birth does not actually reduce venous compression, study says.
New research is challenging what many obstetricians and physician anesthesiologists believe is the best way to position women during labor. According to a study published in Anesthesiology, the traditional practice of positioning women on their side does not effectively reduce compression of the inferior vena cava, a large vein located near the abdominal area that returns blood to the heart, as previously thought. "It is widely believed that lying women flat on their back during labor can lead to dangerously low blood pressure caused by the compression of both the inferior vena cava and the aorta due to the weight of the fetus," said Dr. Hideyuki Higuchi, study author from Tokyo Women's Medical University. "It is accepted by many physicians that positioning women on their side, with hips tilted at 15 degrees, during childbirth reduces this complication. However, our research found no evidence of aortic compression in pregnant women in any position and the recommended degree of tilt that most physicians follow did not reduce compression of the inferior vena cava at all. This is the first study to challenge this antiquated practice." In the study, magnetic resonance images (MRI) of ten pregnant women at full term and ten non-pregnant women were obtained for measurement of the abdominal aorta, the largest artery in the abdominal cavity, and the inferior vena cava. Measurements were taken while the women laid flat on their back and while tilted at 15, 30, and 45 degrees. Foam was placed under the right side of the study participants to achieve the desired amount of tilt. The study found that abdominal aortic blood volume did not differ significantly between pregnant and non-pregnant women regardless of the position in which they were placed. Conversely, inferior vena cava blood volume was significantly lower in pregnant women than in non-pregnant women when the women were positioned flat on their back, indicating almost complete compression of the vein. Inferior vena cava blood volume did not increase at 15 degrees, but partially increased at 30 degrees. An accompanying editorial commented favorably on the study's results, but offered a word of caution: "Although it would be great to be able to conclude by saying all of our patients in the delivery room should be placed in at least 30 degrees left lateral tilt after regional anesthetic, I have serious doubts that our obstetric colleagues would find it a reasonable position for cesarean delivery, particularly in obese patients," said editorial author Dr. Craig Palmer from the University of Arizona College of Medicine. "There quite probably are patients for whom the modest (15 degree) tilt we apply has a salutary effect. However, I will have to be less dogmatic about the practice. Kudos to the authors of this study for revisiting an 'ancient' practice, applying current technology to the matter, and shedding new light on an old routine." The article can be found at: Higuchi et al. (2015) Effect of Lateral Tilt Angle on the Volume of the Abdominal Aorta and Inferior Vena Cava in Pregnant and Nonpregnant Women Determined by Magnetic Resonance Imaging.

Gravitational waves discovery now officially dead

Combined data from South Pole experiment BICEP2 and Planck probe point to Galactic dust as confounding signal.
A team of astronomers that last year reported evidence for gravitational waves from the early Universe has now withdrawn the claim. A joint analysis of data recorded by the team's BICEP2 telescope at the South Pole and by the European spacecraft Planck has revealed that the signal can be entirely attributed to dust in the Milky Way rather than having a more ancient, cosmic origin.

The European Space Agency (ESA) announced the long-awaited results on January 30, a day after a summary of it had been unintentionally posted online by French members of the Planck satellite team and then widely circulated before it was taken down.

The hepatitis-liver cancer connection...
Using whole genomic sequencing, scientists from RIKEN in Japan have for the first time demonstrated the profound effect that chronic hepatitis infection and inflammation can have on the genetic mutations found in tumors of the liver, potentially paving the way to a better understanding of the mechanisms through which these chronic infections can lead to cancer. Recent studies have shown that particularly in Asia, infection with either hepatitis B or C is often associated with such cancers.
For the study, which was published in Nature Communications, the group performed whole genomic sequencing on 30 individual tumors classified as liver cancer displaying a biliary phenotype. This type of cancer originates in the liver, but is different from hepatocellular carcinoma, the dominant form of primary liver cancer, and is generally more aggressive, with poorer prognosis. They compared the data with 60 of the more-common hepatocellular carcinoma tumors. To study gene expression, they then examined RNA sequencing data from 25 of the biliary-phenotype cancers and 44 hepatocellular cancers.
Surprisingly, they found that although the patterns of gene expression—as shown by the RNA sequencing—differed between the hepatocellular carcinomas and the liver cancers with biliary phenotype and depended on the histological type, the overall pattern of mutations in the cells was actually similar between the tumors—of either type—that had emerged in patients who had had infections with either hepatitis C or B, and were different in patients without such infections. This same kind of clustering is also found in cancers with well-understood etiologies, such as melanoma (UV light) and lung cancer (smoking). According to Hidewaki Nakagawa of the RIKEN Center for Integrative Medical Sciences, who led the team, "This is an interesting finding and could indicate that the cancers—even of different histological types—in patients with hepatitis infections could be derived from similar cells, perhaps hepatic progenitor cells. In patients without hepatitis, we did not find any clustering, and this indicates that their cancers might have a very different cellular origin."

Through the analysis, researchers were also able to identify changes in mutations that are associated with more aggressive biliary-type liver cancers. Specifically, they found that mutations of KRAS and IDHs, which are linked to more aggressive cancers, were less common in the cancers in patients with chronic hepatitis.

Norovirus, the most common cause of gastroenteritis in the world, can be killed with "cold plasma," researchers in Germany have reported.

The virus, which elicits vomiting and diarrhea, has gained international notoriety for causing outbreaks on cruise ships.

However, such incidents represent merely a fraction of the tens of millions of cases that occur around the world each year.

The research appears in mBio journal.

Preventing norovirus outbreaks is complicated by the fact that the virus is highly resistant to several different chemical disinfectants.

Bleach, a chlorine-based solution, is currently the most effective treatment, but researchers are seeking more convenient alternatives.

One such alternative is cold plasma, also known as non-thermal plasma. This "fourth state of matter" consists of ionized gas molecules at room temperature. These ions can destroy many kinds of microbes, but their effect on viruses was less clear.
