                                                     WE LOVE SCIENCE HERE

     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!"

"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!

Nutrition deficiency caused by climate change

Evidence builds for lessening of certain micronutrients, protein in plants

A dinner plate piled high with food from plants might not deliver the same nutrition toward the end of this century as it does today. Climate change could shrink the mineral and protein content of wheat, rice and other staple crops, mounting evidence suggests.

Selenium, a trace element essential for human health, already falls short in diets of one in seven people worldwide. Studies link low selenium with such troubles as weak immune systems and cognitive decline. And in severely selenium-starved spots in China, children’s bones don’t grow to normal size or shape. This vital element could become sparser in soils of major agricultural regions as the climate changes, an international research group announced online February 21 in Proceedings of the National Academy of Sciences.

Likewise, zinc and iron deficiencies could grow as micronutrients dwindle in major crops worldwide, Harvard University colleagues Samuel Myers and Peter Huybers and collaborators warned in a paper published online January 6 in the Annual Review of Public Health. Futuristic field experiments on wheat and other major crops predict that more people will slip into nutritional deficits late in this century because of dips in protein content, Myers reported February 16 at the Climate and Health Meeting held in Atlanta.

In a remote West African village, a revolutionary genetic experiment is on its way — if residents agree to it...

Scientists in Burkina Faso are engaged in what could be the most promising, and perhaps one of the most frightening, biological experiments of our time. They are preparing for the possible release of swarms of mosquitoes that, until now, have been locked away in a research lab behind double metal doors and guarded 24/7.

The goal: to nearly eradicate the population of one species of mosquito, and with it, the heavy burden of malaria across Africa.

These scientists are planning to release mosquitoes equipped with “gene drives,” a technology that overrides nature’s genetic rules to give every baby mosquito a certain trait that normally only half would acquire. Once such an insect gets out into the wild, it will move indiscriminately and spread its modified trait without respect for political borders.

No living thing — no mammal, insect, or plant — with a gene drive has ever been set free. But if all goes as planned, it might happen here, in a remote village of about a thousand people, where the residents don’t even have a word for “gene.”

Despite such barriers, this is in some ways the most logical place to carry out the experiment. Nowhere does malaria exact a higher toll than here in sub-Saharan Africa, where hundreds of thousands die from the disease every year. And Burkina Faso already houses one of Africa’s highest-profile malaria research laboratories.

scientists still face a challenge: making sure that people understand and accept the newfangled genetic technology behind it all. That means building trust and doing basic education — explaining not only the impact of genetically engineered insects arriving in their homes, but also what genetics is in the first place.

Time crystals: New form of matter...

We have heard about three dimensional crystals such as salt, snow flakes etc. Now two groups of scientists have created a new kind of crystals, whose existence was first suggested by Wilczek who proposed time crystals in 2012, while wondering whether certain properties changing in time, rather than in space, could yield new phases of matter,  repeats a pattern across the fourth dimension—time.

Harvard scientists created time crystals from synthetic diamond while a University of Maryland team used charged atoms of the element ytterbium.  Two groups of scientists report that they’ve observed exotic time crystals, systems of atoms whose properties arrange themselves, or “crystallize” in time like the way solids can crystallize in space. The two groups’ vastly different atomic arrangements aren’t perpetual motion machines, weapons, or time travel devices—but their strange behavior sheds light on a whole new class of materials with properties different from any solid, liquid or gas you’ve ever encountered.

An appropriately tuned laser would flip the spins by 180 degrees. A second, identical laser burst would return the spins to their original position.

Any slight shifts to the frequency of the laser pulses would cause the ions spins to rotate by an amount different from 180 degrees. So they would not reach their starting orientation after two bursts from the spin-flip laser.

In a time crystal, the additional laser pulses introduce disorder and interactions, which make the system resilient to shifts in the frequency of the spin-flip laser. So the system cycles through a repeating pattern.

The researcher also verified that the time crystals were a closed system, and thus no energy is lost outside to the world. Also, the matter appears to have property similar to supercomputers.

Malaria parasites make human hosts attract mosquitoes...

Malaria parasites produce a chemical that causes infected people to emit odours attractive to mosquitoes. The chemical, HMBPP, stimulates red blood vessels to produce carbon dioxide and volatile compounds. The discovery of the chemical’s role could be key to controlling malaria, a major disease.

The malaria parasite Plasmodium falciparum produces a molecule which makes infected humans emit carbon dioxide and other volatile compounds that attract mosquitoes and help them spread the disease more efficiently, a study has found. 

The molecule, HMBPP, works by stimulating red blood cells, says Ingrid Faye, researcher at the Department of Molecular Bioscience, Stockholm University (SU) and corresponding author of the study, published in Science  (February 9, 2017).

How science is getting attacked...

US government is not alone in questioning the findings of science. In the past five years, the people and government of Germany have turned against nuclear power; Thabo Mbeki, while president of South Africa, denied that human immunodeficiency virus (HIV) causes AIDS; and the Harper administration of Canada forbade its scientists to speak freely about climate change (this went on for nearly a decade), among other examples. Here in the US, a number of prominent politicians deny scientists’ findings that the first years of the 21st century have been the planet’s hottest on record, and that 2014, 2015, and 2016 have each succeeded the previous as the hottest year on record. Of course, denial is a far easier stance for governments to take: Denying global warming means there’s no reason to do anything about it.

A pair of bacterial genes may enable genetic engineering strategies for curbing populations of virus-transmitting mosquitoes.

Bacteria that make the insects effectively sterile have been used to reduce mosquito populations. Now, two research teams have identified genes in those bacteria that may be responsible for the sterility, the groups report online February 27 in Nature and Nature Microbiology.

Wolbachia bacteria “sterilize” male mosquitoes through a mechanism called cytoplasmic incompatibility, which affects sperm and eggs. When an infected male breeds with an uninfected female, his modified sperm kill the eggs after fertilization. When he mates with a likewise infected female, however, her eggs remove the sperm modification and develop normally.

When the researchers took two genes from the Wolbachia strain found in fruit flies and inserted the pair into uninfected male Drosophila melanogaster, the flies could no longer reproduce with healthy females.

When pollution becomes too high to negate the goodness of exercise? A disaster!

Air pollution is just one of the many crises we’re dealing with across the world. The health impact of air pollution continues to astound us and if you’re the health conscious sort, a new study is bound to upset you. It states that some cities are so polluted that 30 minutes of exercise does more harm than good.

The study was published in the journal Preventive Medicine and it used cycling as the sample activity to simulate exercise. The study assumed an average cycling speed of 12-14 kilometres an hour to check its impact on the body. The results are shocking.

http://www.sciencedirect.com/science/article/pii/S0091743516000402

In north Indian cities such as Allahabad and Gwalior, cycling for more than 30 minutes is bad for health, the study said. In New Delhi, one hour is when the 'breakeven point' is reached. If PM2.5 levels are above a certain level, then any kind of outdoor activity could lead to serious health problems even without exercise. It's not hard to see why the effect will be severe on those who run or cycle outdoors in that kind of weather.

The study did use cycling as a way to measure impact of pollution on exercise but it says that the same numbers apply to similar activities such as slow jogging. If you are training for half marathon, you might want to consider alternatives such as training indoors. The report claims that breathing polluted air has been linked with heart disease, stroke, and even some cancers.
