         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!"

Scientists have opened the blood-brain barrier for the first time
For the first time in humans, researchers have managed to penetrate the brain’s protector, meaning that doctors will be able to deliver drugs to previously inaccessible parts of the brain.
The blood-brain barrier is a network of cells that separates the brain from the rest of the body, preventing harmful toxins and chemicals in the blood stream from entering the brain tissue. This blocking mechanism makes it very difficult to deliver drugs to the brain for the treatment of neurodegenerative disorders and cancer.

This protective barrier has been opened in animals but never in humans, until now. A medical start-up company CarThera in France, have opened and closed the barrier on demand with the help of an ultrasound brain implant and an injection of microbubbles.

The findings were presented last week at the Focused Ultrasound symposium in the US by Michael Canney, a neuroscientist at CarThera. The study involved the treatment of glioblastoma - the most aggressive form of brain cancer - in four patients. Patients with glioblastoma usually need surgery to remove the tumour, after which they are given chemotherapy drugs to destroy any remaining cancerous cells. The blood-brain barrier becomes leaky when a tumour is present, so a small amount of the drugs are able to enter the brain.
To penetrate the barrier, the surgeons first inserted a tiny ultrasound brain implant into the patients’ skulls. They then injected microbubbles to counter the ultrasound imaging. When the ultrasound’s pulses collided with the bubbles, it caused them to vibrate, pushing apart the cells of the blood-brain barrier. To confirm the observations, an MRI scan showed that the microbubbles were effectively crossing the blood-brain barrier.
The team estimate that the novel approach keeps the barrier open for up to six hours, allowing enough time to deliver high dosages of the drugs.

Cancer cells can ‘infect’ normal neighbours

Tiny RNAs shed by tumours can transform healthy cells into cancerous ones.
When a cancer cell throws out its trash, it can turn healthy neighbours into fellow tumour cells, researchers have found.

Many cells, including cancerous ones, shed thousands of tiny membrane-bound vesicles called exosomes that contain proteins, DNA and RNA. The process is thought to be a waste-management system, but it may also facilitate cell-to-cell communication: some of these vesicles can then merge with other cells and dump their payload inside.

In a study published online on 23 October in Cancer Cell1, researchers show that when human breast-cancer exosomes can cause tumours when mixed with normal cells then injected into mice. The results could pave the way to finding markers to monitor the progression of cancer, and possibly even point to targets for therapies.

The marvels of Science!
'Dead' hearts transplanted into living patients in world first

In a breakthrough, a team of doctors, including an Indian-origin surgeon, today said they have successfully performed the world's first heart transplant in Australia using a "dead heart", a major development that could save many lives.

The procedure, using hearts that had stopped beating, has been described as a "paradigm shift" that will herald a major increase in the pool of hearts available for transplantation.

It is predicted the breakthrough will save the lives of 30 per cent more heart transplant patients.

Until now, transplant units have relied solely on still- beating donor hearts from brain-dead patients.

But the team at the lung transplant unit of St Vincent's Hospital here announced they had transplanted three heart failure patients using donor hearts that had stopped beating for 20 minutes.

It was possible thanks to a new technology. The incredible development of the preservation solution with this technology of being able to preserve the heart, resuscitate it and to assess the function of the heart has made this possible.

Hearts are the only organ that is not used after the heart has stopped beating - known as donation after circulatory death.

Beating hearts are normally taken from brain-dead people, kept on ice for around four hours and then transplanted to patients.

The novel technique used in Sydney involved taking a heart that had stopped beating and reviving it in a machine known as a "heart-in-a-box".

The heart is kept warm, the heartbeat is restored and a nourishing fluid helps reduce damage to the heart muscle.

U.S. Suspends Risky Disease Research
The government will cease funding "gain-of-function" studies that make viruses more dangerous
The US government surprised many researchers on October 17 when it announced that it will temporarily stop funding new research that makes certain viruses more deadly or transmissible. The White House Office of Science and Technology Policy is also asking researchers who conduct such ‘gain-of-function’ experiments on influenza, severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS) to stop their work until a risk assessment is completed — leaving many unsure of how to proceed.
But, some microbiologists call the plan “a knee-jerk reaction”. “There is really no evidence that these experiments are in fact such high risk,” he says. “A lot of them are being done by very respectable labs, with lots of precautions in place.”

Brain games don't benefit the elderly much say scientists:

A joint statement signed by 69 leading psychologists and neuroscientists from around the world has criticized the "exaggerated and misleading claims" made by commercial interests that "brain games" help senior citizens prevent declining brain functions. The statement was issued by the Stanford Center for Longevity and the Max Planck Institute for Human Development.

Laura Carstensen, a Stanford psychology professor and the director of the Center for Longevity, was quoted by a Stanford statement saying that as baby boomers enter their golden years, commercial companies are all too often promising quick fixes for cognition problems through products that are unlikely to produce broad improvements in everyday functioning.

"It is customary for advertising to highlight the benefits and overstate potential advantages of their products," she said. "But in the case of brain games, companies also assert that the products are based on solid scientific evidence developed by cognitive scientists and neuroscientists. So we felt compelled to issue a statement directly to the public."

While brain games may target very specific cognitive abilities, there is very little evidence that improvements transfer to more complex skills that really matter, like thinking, problem solving and planning, according to the scholars. While it is true that the human mind is malleable throughout a lifetime, improvement on a single task - like playing computer-based brain games - does not imply a general, all-around and deeper improvement in cognition beyond performing better on just a particular game, according to them.

"We object to the claim that brain games offer consumers a scientifically grounded avenue to reduce or reverse cognitive decline when there is no compelling scientific evidence to date that they do. ... The promise of a magic bullet detracts from the best evidence to date, which is that cognitive health in old age reflects the long-term effects of healthy, engaged lifestyles."

As the researchers point out, the time spent on computer games takes away from other activities like reading, socializing, gardening and exercising that may benefit cognitive functions.

Marvels of medical science:

Paralysed man Darek Fidyka walks again after pioneering surgery

Medical team regrow cells of patient’s severed spine in breakthrough that offers hope to millions with disability.

A man who was completely paralysed from the waist down can walk again after a British-funded surgical breakthrough which offers hope to millions of people who are disabled by spinal cord injuries.

Polish surgeons used nerve-supporting cells from the nose of Darek Fidyka, a Bulgarian man who was injured four years ago, to provide pathways along which the broken tissue was able to grow.

The 38-year-old, who is believed to be the first person in the world to recover from complete severing of the spinal nerves, can now walk with a frame and has been able to resume an independent life, even to the extent of driving a car, while sensation has returned to his lower limbs.

Professor Geoffrey Raisman, whose team at University College London’s institute of neurology discovered the technique, said: “We believe that this procedure is the breakthrough which, as it is further developed, will result in a historic change in the currently hopeless outlook for people disabled by spinal cord injury.”

The surgery was performed by a Polish team led by one of the world’s top spinal repair experts, Dr Pawel Tabakow, from Wroclaw Medical University, and involved transplanting olfactory ensheathing cells (OECs) from the nose to the spinal cord.

OECs assist the repair of damaged nerves that transmit smell messages by opening up pathways for them to the olfactory bulbs in the forebrain.

Relocated to the spinal cord, they appear to enable the ends of severed nerve fibres to grow and join together – something that was previously thought to be impossible.
