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!"

Reading old books without opening them
Scientists have devised a way to read without cracking a volume’s spine or risking paper cuts (and no, we’re not talking about e-books). The new method uses terahertz radiation — light with wavelengths that are between microwave and infrared waves — to view the text of a closed book. The technique is not meant for your average bookworm, but for reading rare books that are too fragile to open.
Barmak Heshmat of MIT and colleagues started small, with a nine-page book of thick paper that had one letter inked on each page. By hitting the book with terahertz radiation and looking at the reflected waves, the scientists could read the letters within.
Letters on pages 7 through 9 of a closed book are decoded using terahertz radiation. After isolating the reflected radiation from each page, the technique selects the frequency of radiation that provides the best contrast between ink and paper. An algorithm decodes the letters and then their locations inside the book.
Differences in the way the radiation interacts with ink and paper allowed the researchers to pick out shadowy outlines of the letters, and a letter-recognition algorithm automatically decoded the characters. The scientists could tell one page from another by using precise timing information: On the later pages, the waves penetrated deeper before reflecting and, therefore, took longer to return.
Historians also may be able to use the technique to find an artist’s signature hidden beneath layers of a painting.
AT LEAST two trillion galaxies — 10 times more than scientists thought — exist within the observable universe. And we can’t even see most of them.
A group of international astronomers compiled 20 years of images from the Hubble Space Telescope and other international observatories to create a 3D model of the 200 billion galaxies already estimated to exist.
But the model instead revealed that there are at least one trillion eight hundred billion more out there. Only 10 per cent of these are visible to us even with our strongest telescopes.
“It boggles the mind that over 90 per cent of the galaxies in the universe have yet to be studied,” said Christopher Conselice, who led the study published Thursday in The Astrophysical Journal.
Since the scientists were observing deep space, they essentially gazed 13 billion light-years into the past and discovered that the early universe contained more galaxies than it does today. Many of those galaxies have since merged to form larger celestial objects.
Extreme microbes living in hostile locations on Earth may be munching on cosmic rays that zip through space, says a study of a peculiar bacterium thriving in a dark gold mine.
organisms that munch on galactic cosmic rays could even survive on rogue planets which are not bound to any star and drift throughout interstellar space.
Life on Earth relies primarily on light from the sun. Photosynthesis takes place in the presence of sunlight, which, in turn, supplies the energy and nutrients that are used by other organisms in order to survive. Still, in the absence of light, organisms can use other sources of energy, such as chemical energy or heat energy, as suggested by previous studies.
Prior researches have even shown that life-forms can feed off the ionizing radiation - which has sufficient energy to charge or ionize atoms from radioactive materials.
"Most research on ionizing radiation concerns its potentially harmful effects, such as damage to DNA," Atri told. "But a bacterium that is cut off completely from sunlight and the rest of the biosphere can survive completely off of ionizing radiation."
The galactic cosmic rays hold much higher energy than other radiation sources on Earth. When they strike the atmosphere or a planet's surface, they generate a gush of particles such as neutrons, positrons, and electrons along with the dangerous gamma rays. Atri said galactic cosmic rays could be found everywhere and they have an enormous amount of energy that helps them to penetrate even through the surfaces of planets.
Using computer simulations, Atri concluded that galactic cosmic rays could account for a steady flow of energy for organisms living underground. The energy flow might extend to potential life on other planets.
In order to prevent distortion of facts and makescientific literature more credible, the Ministry of Science and Technology is considering a plan under which books related to science could be graded and validated by experts.
The experts will comprise scientists from several laboratories under the Ministry of Science and Technology, which has three departments and over 50 institutes researching on a wide range of topics.
The exercise would be voluntary and is aimed at making science literature more credible.
"We have realised that a lot of distortion takes place while presenting scientific facts and concepts. For example, we came across a book under which the concept of osmosis was fundamentally wrong.
"There are several such instances where facts are distorted," said Manoj Kumar Patairiya, Director of National Institute of Science Communication and Information Resources (NISCAIR).
NISCAIR, is an institute under the Council of Scientific and Industrial Research (CSIR), a department under the Ministry of Science and Technology.
Patairiya said scientific journals, newspapers and regular journals have some level of quality control but same is not the case when someone publishes a book on science.
Referring to new discoveries pertaining to the formation of universe and earth, Patairiya said, several books still carry the age-old concepts on how earth came into existence.
"At a time when we have a system of quality control for everything, then why not for science literature. The plan is to validate, accredit science books by a core team of experts. We have resources comprising experts from various institutes under the Ministry of Science and Technology.
"The publishers can approach us and we can vet the material before it goes for publishing. This move will also help the publishers and authors," Patairiya said.
"We are planning to start it for Hindi and English and extend it to other regional languages later," Patairiya said.

A three people who built motors and devices a fraction the size of a human hair has set the stage for a new type of industry
Bernard Feringa, Jean-Pierre Sauvage and Sir J. Fraser Stoddart got it for building machines on the tiniest of scales—the nanometer scale, a thousand times smaller than the width of a hair, or a billionth of a meter. Molecular motors and elevators and muscles, and even miniature four-wheel-drive cars, were cited by the Nobel Committee as some of the inventions of the three scientists, who mastered construction techniques and the ability to create energy to make things move.
Nanoscale machines based on these design principles have already begun to shape the future of medicine - nanobots that can be sent through blood vessels and nanomaterials that can monitor vital organ health.
Strange phenomena explanations get Nobel Physics prizes
The 2016 Nobel Prize for Physics went to work explaining the topological underpinnings of superconductivity and other strange phenomena.
The Nobel Prize in Physics 2016 was split, with one half going to David J. Thouless at the University of Washington, and the other half going to F. Duncan M. Haldane at Princeton University and J. Michael Kosterlitz at Brown University. The Prize was awarded for the theorists’ research in condensed matter physics, particularly their work on topological phase transitions and topological phases of matter, phenomena underlying exotic states of matter such as superconductors, superfluids and thin magnetic films. Their work has given new insights into the behavior of matter at low temperatures, and has laid the foundations for the creation of new materials called topological insulators, which could allow the construction of more sophisticated quantum computers.
Topology is a branch of mathematics that studies properties that only change incrementally, in integer steps, rather than continuously.
This work “has told us that quantum mechanics can behave far more strangely than we could have guessed, and we really haven’t understood all the possibilities yet".
The 2016 Nobel Prize in Medicine goes to pioneering work on autophagy
The 2016 Nobel Prize in Medicine or Physiology was given to Yoshinori Ohsumi
of the Tokyo Institute of Technology for basic research describing a fundamental housekeeping function of the cell—a process called autophagy. From the Greek for "self-eating," autophagy is the straightforward mechanism by which a cell digests certain large internal structures and semi-permanent proteins in a continual cleanup process. The process may have evolved as a response to starvation, in which cells cannibalized some of their own parts in order to continue living. But over the eons it has become an essential tool used by cells to maintain their own health, resist infection and possibly even fight cancer.
Autophagy is particularly important in cells such as neurons, which tend to live a long time and thus need to be constantly renewed and refurbished. The process takes place in the cytoplasm, the jelly-like fluid that fills the cell outside the nucleus. The workings of the cytoplasm are so complex . . . that it is constantly becoming gummed up with the detritus of its ongoing operations. Autophagy is, in part, a cleanup process: the trash hauling that enables a cell whose cytoplasm is clotted with old bits of protein and other unwanted sludge to be cleaned out." Problems with autophagy may contribute to neuronal damage in Alzheimer's, Parkinson's and other neurodegenerative diseases.
Ohsumi chose the transport of materials to the yeast vacuoles as his research project and got several awards for his pioneering work. Autophagy is fundamental to a cell's continued good health and have even specialized in describing particular types of autophagy—such as the digestion and degradation of worn-out mitochondria (the powerhouse of the cell) and the endoplasmic reticulum, which assembles, folds and delivers proteins to the rest of the cell.
Galaxy made of dark matter? Among the thousand-plus galaxies in the Coma cluster, a massive clump of matter some 300 million light-years away, is at least one — and maybe a few hundred — that shouldn’t exist.
Dragonfly 44 is a dim galaxy, with one star for every hundred in our Milky Way. But it spans roughly as much space as the Milky Way. In addition, it’s heavy enough to rival our own galaxy in mass, according to results published in the Astrophysical Journal Letters at the end of August. That odd combination is crucial: Dragonfly 44 is so dark, so fluffy, and so heavy that some astronomers think it will either force a revision of our theories of galaxy formation or help us understand the properties of dark matter, the mysterious stuff that interacts with normal matter via gravity and not much else. Or both.
There are several theories going around in the Astronomy circles now about them. And people are trying to figure out things and find answers to the Qs 'why, what, how, whether etc.'.
World's first baby born with 'three parents' reports New Scientist
A Jordanian couple has been trying to start a family for almost 20 years. Ten years after they married, she became pregnant, but it ended in the first of four miscarriages.
In 2005, the couple gave birth to a baby girl. It was then that they discovered the probable cause of their fertility problems: a genetic mutation in the mother’s mitochondria. Their daughter was born with Leigh syndrome, which affects the brain, muscles and nerves of developing infants. Sadly, she died aged six. The couple’s second child had the same disorder, and lived for 8 months.
Using a controversial “three-parent baby” technique , the boy was born on 6 April 2016. He is showing no signs of disease.
The boy’s mother carries genes for Leigh syndrome, a fatal disorder that affects the developing nervous system. Genes for the disease reside in DNA in the mitochondria, which provide energy for our cells and carry just 37 genes that are passed down to us from our mothers. This is separate from the majority of our DNA, which is housed in each cell’s nucleus.
Around a quarter of her mitochondria have the disease-causing mutation. While she is healthy, Leigh syndrome was responsible for the deaths of her first two children. The couple sought out the help of John Zhang and his team at the New Hope Fertility Center in New York City.
Zhang has been working on a way to avoid mitochondrial disease using a so-called “three-parent” technique. In theory, there are a few ways of doing this. The method approved in the UK is called pronuclear transfer and involves fertilising both the mother’s egg and a donor egg with the father’s sperm. Before the fertilised eggs start dividing into early-stage embryos, each nucleus is removed. The nucleus from the donor’s fertilised egg is discarded and replaced by that from the mother’s fertilised egg.
But this technique wasn’t appropriate for the couple – as Muslims, they were opposed to the destruction of two embryos. So Zhang took a different approach, called spindle nuclear transfer. He removed the nucleus from one of the mother’s eggs and inserted it into a donor egg that had had its own nucleus removed. The resulting egg – with nuclear DNA from the mother and mitochondrial DNA from a donor – was then fertilised with the father’s sperm.
Zhang’s team used this approach to create five embryos, only one of which developed normally. This embryo was implanted in the mother and the child was born nine months later.
The team avoided destroying embryos, and used a male embryo, so that the resulting child wouldn’t pass on any inherited mitochondrial DNA.
A remaining concern is safety. Last time embryologists tried to create a baby using DNA from three people was in the 1990s, when they injected mitochondrial DNA from a donor into another woman’s egg, along with sperm from her partner. Some of the babies went on to develop genetic disorders, and the technique was banned. The problem may have arisen from the babies having mitochondria from two sources.
When Zhang and his colleagues tested the boy’s mitochondria, they found that less than 1 per cent carry the mutation. Hopefully, this is too low to cause any problems; generally it is thought to take around 18 per cent of mitochondria to be affected before problems start.
The child will be monitored and we need more of these cases to judge teh effectiveness of this technique.
Egyptian researchers have developed a bandage embedded with nanoparticles for the treatment of wounds using the anti-epilepsy drug Phenytoin, known for its capacity to treat skin injuries.
The bandage can heal wounds in a few days, after just one application to soft tissue. Wounds normally take several days to a few weeks to heal completely, and some may only heal after several months or up to two years.
Even though Phenytoin is known for its potential to accelerate wound healing, some of its properties limit its effectiveness. For example, a low percentage of the drug can be absorbed into the blood circulation. It also doesn’t cover the entire wounded area, which interferes with the efficiency of healing.
To overcome these challenges, a research team from Zewail City of Science and Technology in Egypt, led by Ibrahim M. El-Sherbiny, the director of the Center for Materials Science, embedded the drug into a bandage consisting of nanoparticles carried on nanofibers.
“This allowed a well-controlled release of phenytoin, distributing it effectively, which, boosts its efficiency.”
The results of the study, published last May in the Journal of Applied Materials & Interfaces, also confirmed an improvement in the formation of granulation tissue — a fibrous connective tissue which grows from the base of the wound until it fills it, and replaces the blood clot that formed after the wound was received.
