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!"

Plastic degrading enzyme created by scientists...
Scientists have created a substance capable of “eating” plastic that could help tackle the world’s pollution problem.
The substance is based on an enzyme – a “biological catalyst” – first produced by bacteria living in a Japanese recycling centre that researchers suggested had evolved it in order to eat plastic.
Dubbed PETase for its ability to break down the PET plastic used to make drinks bottles, the enzyme accelerated a degradation process that would normally take hundreds of years.
Fine-tuning this naturally produced enzyme allowed a research team to produce something capable of digesting plastic more effectively than anything found in nature.
By breaking down plastic into manageable chunks, the scientists suggest their new substances could help recycle millions of tonnes of plastic bottles.
Plastic is notoriously resistant to natural degradation, and the discovery of the Japanese plastic-eating bacteria in 2016 was heralded by experts and commentators alike as a potential natural solution to plastic pollution.
While attempting to verify these claims, University of Portsmouth biologist Professor John McGeehan and his colleagues accidentally created a super-powered version of the plastic-eating enzyme.
During an investigation of the enzyme’s structure, the scientists made a slight tweak to the part thought to be involved with plastic digestion.
Doing so ramped up the ability of the enzyme to degrade PET, and also gave it the ability to degrade an alternative form of PET known as PEF.
European Space Agency maps second magnetic field around Earth.
A second layer of the magnetic field has been found around the earth. According to the reports, the magnetic field was discovered by the trio of satellites which were used to study the magnetic fields.
The mission was named “Swarm” which was launched in the year 2013. Four years of continuous efforts have proved fruitful, a lot of data was collected and as a result, it contributed to the mapping of the latest discovery in the world of space technology. The satellites revolve around the earth at 300-530 km.
The newly discovered magnetic field is about 2-2.5 nanotesla at the satellite altitude which is about 20,000 times weaker than the earth’s existing magnetic field. The scientist stated that they have used Swarm to measure the magnetic signals of the tides from the ocean surface to the seabed.
Getting on the practical aspect of the newly discovered magnetic field it could be used to hone the models of global warming by naming the monitoring patterns of the heat energy as they change their positions globally. But in addition to this, the tidal magnetic signal also induces a weak magnetic response under the deep seabed. The findings will be further used to study the electrical properties of the earth lithosphere as well as the upper mantle.

Scientists here say Dog is a biodiversity enemy
According to a new study, Canis lupus familiaris (dog, for short) is an ‘invasive’ species in many ecosystems! Like the Japanese kudzu vine or the infamous Lantana, dogs are a non-native introduced species that are wreaking havoc on the ecological balance of many sensitive ecosystems. Now, a study by researchers from the Ashoka Trust for Research in Ecology and the Environment explores the effect of free-ranging dogs, or strays, on their surroundings in India.
Previous studies have shown that domesticated dogs have imperilled 188 threatened species of animals and caused 11 mass extinctions, globally! Domestic dogs have been considered as invasive mammalian predators. After cats and rodents, they are the third most damaging invasive predators.
In countries like India, where the population of stray dogs are surging by the day without checks and bounds by a governing body, these dogs turn feral—a state in which they are neither truly wild not truly domesticated. “Unlike cats and rats which perhaps target smaller sized animals, feral dogs can target a larger range of prey size as predators as they can hunt in packs. Their impacts are as detrimental as cats and rats, though cats and rats have reported higher extinction for biodiversity.
The study shows that the threat from dogs on wildlife is real and could come in the way of conservational efforts. So, what can we do to curb this conflict? Managing dog population is the key, say the researchers.
The researchers opine that in order to protect local wildlife and ensure a good quality of life for dogs, carefully planned population control programs should be implemented near protected forest areas.
Domesticated dogs are adding a new dimension to the threats many species of wildlife are already facing due to habitat loss, deforestation, encroachment, etc. Man’s best friend is turning out to be biodiversity’s biggest enemy, as this research shows.

Eating very hot chillies might trigger reversible cerebral vasoconstriction syndrome — a temporary narrowing of arteries in the brain.
His is the first known instance of reversible cerebral vasoconstriction syndrome — a temporary narrowing of arteries in the brain — to be tied to eating a hot pepper, researchers report April 9 in British Medical Journal Case Reports. Such narrowed arteries can lead to severe pain called “thunderclap headaches” and are often associated with pregnancy complications or illicit drug use.
During a hot-pepper-eating contest, the man ate a chili dubbed the Carolina Reaper, named by Guinness World Records as the hottest pepper in the world. The Carolina Reaper is over 200 times as spicy as a jalapeño. About a minute later, he reported experiencing splitting headaches that came and went over two days before he sought treatment.
Initial tests failed to find anything out of the ordinary. But a CT scan of blood vessels in the man’s brain showed severely narrowed arteries. After treatment, including hydration and pain medication, the headaches stopped. When the researchers imaged his brain five weeks later, the arteries had returned to their normal size.
Cancer is a dreaded disease. And chemotherapy has its pitfalls but becomes unavoidable sometimes. But how about making chemotherapy more safer and effective?
That is exactly what researchers at the Indian Institute of Technology Kanpur have proposed - a new model for the transport of anti-cancer drugs to human brain tumours using liposomes—a small sac-like structure that transports nutrients in our cells.
Liposomes, like our cell membranes, are made of molecules called phospholipids. In a cell membrane, these molecules are arranged into two layers. However, in a liposome, the two layers meet to form a hollow sphere filled with water. In this study, the researchers propose to replace the water in the empty area with anti-cancer drug molecules—a technique they claim improves transport of the drug molecules—to create a nanosized drug delivery system.
Besides, the lipid layer in the liposomes acts as a protective coat and prevents the anti-cancer drug from affecting healthy cells. Since these liposomes are in the bloodstream, they circulate for longer and collect at the tumour site, helping more of the drug reach their target cells. This approach causes less damage to the healthy cells of the body.
There is another aspect of tumours that makes it hard to use anti-cancer drugs in treatment without damaging the surrounding healthy cells. Tumorous cancer cells vary in their organisation, function and structure, making it difficult for drugs to target them specifically. Also, the veins and arteries that supply blood to a tumour, twist and coil, making it more difficult to administer the anti-cancer drug into a tumour. Since the endothelial cells present in the tumour blood vessels are widely spaced out, drugs tend to leak out into the interstitial spaces between the cells, reducing the efficacy of the drugs.
The researchers analysed the structure of blood vessels of the cancerous brain tissue using dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) by taking multiple snapshots of the tumor vasculature over a period of time and comparing them. Using this data, they predicted the transport, accumulation and efficacy of the chemotherapeutic drug in a tumour with computational fluid dynamics—a branch of fluid mechanics that uses numerical analysis and data structures to solve and analyse problems that involve fluid flows. They also predicted the distribution of the drug in a tumour. “With the help of this model, we can predict the preferential deposition of chemotherapeutic drugs inside a tumour, thus predicting the healing of a tumour for a specific patient, provided we have the initial medical images of that patient".
The results of the study showed that a high amount of the anti-cancer drug Doxorubicin, which was not encapsulated by a liposome, accumulated in the interstitial spaces between tumour cells. This accumulation could potentially cause adverse side-effects like swelling, reddening and peeling of skin from the hands and feet. In contrast, the liposome-encapsulated drug remained inside a tumour for a longer time. They also found that the high concentration of liposome-coated drug aggregated at the tumour site and increased the therapeutic efficiency of the liposomal anticancer drug.
Medical imaging of the tumours helps predict the deposition of the anti-cancer drug in a tumour for a patient and look for chemotherapeutic drug options that could better suit him/her. This ability also allows doctors to develop a specific chemotherapeutic approach for each patient, based on the structure of their brain tumour and the blood vessels surrounding it.

World renowned physicist Stephen Hawking has died at the age of 76.
He died peacefully at his home in Cambridge in the early hours of Wednesday, his family said.
The Briton was known for his work with black holes and relativity, and wrote several popular science books including A Brief History of Time.
At the age of 22 Prof Hawking was given only a few years to live after being diagnosed with a rare form of motor neurone disease.
People who received kidneys from donors infected with hepatitis C did not become ill with the virus, thanks to treatment with newer drugs that can cure the disease, a small study reports.
Ten patients not previously infected with hepatitis C took doses of powerful antiviral medications before and after receiving the transplants. None of the patients developed chronic infections, researchers report online March 6 in the Annals of Internal Medicine. The finding could help make more kidneys available for transplants.

Space travel changes your DNA. How much of that is permanent?
While it’s possible for the DNA differences to be a temporary effect on the human body, NASA’s findings reveal otherwise. Approximately 7 percent of Scott Kelly’s DNA changed while he was in space. So, 7 percent of his DNA was altered permanently, while the remaining 93 percent reverted to normal as his body adapted to living on Earth.
