Scientists create artificial nerve cell connections with plastic beadsOctober 8th, 2009 WASHINGTON - In a breakthrough study, scientists have successfully created nerve cell connections with the help of artificial substances, a major advance, which the researchers say, will help make nerve cell repair possible. Scientists from Montreal NeurologicaI Institute and Hospital (The Neuro) and McGill University created the artificial nerve cell connections using plastic beads coated with a substance that encourages adhesion, and attracts nerve cells.
The 'elixir of life' to lengthen lifespan beyond 100yrs comes closer to realityOctober 5th, 2009 LONDON - Taking a step closer towards a wonder pill that could extend people's lifespan by up to 25 years, scientists have claimed that over half of babies born in the new future in the UK and other wealthy nations will live to 100 years. The drug, touted as the "elixir of life" drug, works by using a molecule called spermidine, which helps to protect the body against damaging chemicals known as free radicals.
Natural killer cells help keep immune system in balanceOctober 2nd, 2009 WASHINGTON - Natural killer (NK) cells, part of our immune system, kill cells infected with a given virus. Researchers have now found that the cells also help keep T-cells from over-responding.
Indian origin scientist wins prestigious 'New Innovator Award'September 26th, 2009 WASHINGTON - Vikas Nanda, a scientist of Indian origin, has won the prestigious National Institutes of Health (NIH) Director's New Innovator Award this year. Dr. Nanda is assistant professor of biochemistry and a member of the Center for Advanced Biotechnology and Medicine at UMDNJ-Robert Wood Johnson Medical School.
Cell isolated from bio-clock can still keep timeSeptember 10th, 2009 WASHINGTON - Alexis Webb enters a small room painted dark green, turns off the lights and bends over a microscope over a black box to see a single nerve cell on a glass cover slip glowing dimly - indicating the isolated cell is busy keeping time. Researchers at Washington University in St.
Nerve cells that make us itch identifiedAugust 7th, 2009 LONDON - Neuroscientists have long scratched their heads to solve the puzzle of itching. But now researchers have finally worked out what makes us itch.
An 'eye catching' discovery made among fishJuly 27th, 2009 WASHINGTON - Nearly all animals can detect light, thanks to three types of retinal cells that allow us to see images or distinguish between night and day. Now researchers have discovered in fish yet another type of cell that can sense light and contribute to vision.
Scientists find cell in fish that can sense light and contribute to visionJuly 27th, 2009 WASHINGTON - Researchers at the Johns Hopkins School of Medicine, US, have discovered in fish yet another type of cell that can sense light and contribute to vision. The team of neuroscientists shows that retinal horizontal cells, which are nerve cells once thought only to talk to neighboring nerve cells and not even to the brain, are light sensitive themselves.
Jelly thickener may help grow artificial muscles in futureJuly 14th, 2009 MELBOURNE - In a novel study, Australian researchers are using food thickener used in yoghurts and jellies to develop artificial muscle. Nanotechnology graduate Cameron Ferris, and supervisor Dr.
Are artificial human sperm actually identical to natural kind?July 9th, 2009 LONDON - Scientists are calling for more tests to ensure that artificial sperm created by some British researchers are identical to their natural counterpart, saying that further proof may make them a valuable tool to understand male infertility. Karim Nayernia and his colleagues at the University of Newcastle recently treated male embryonic stem cells (ESCs) with a range of substances, which converted them first into germline stem cells, and finally into spermatogonial stem cells.
What makes us coughJuly 9th, 2009 LONDON - Scientists at the University of Hull have identified a new group of molecules on the surface of nerve cells that make people cough when they are irritated. According to the researchers, the findings could lead to new drugs to treat coughing.
Artificial liver, skin, intestine to revolutionise drug trialsJune 26th, 2009 WASHINGTON - While animal drug trials have been facing huge criticism from ethical groups, scientists have now created artificial organs like liver, skin, intestine and windpipe that may revolutionise the way new medicines are being tested. Developed by Professor Heike Mertsching of the Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB in Stuttgart, in collaboration with Dr.
Lasers can make cheaper, better solar cellsMay 30th, 2009 LONDON - Using lasers to make solar photovoltaic cells that produce electricity from sunshine makes these cells cheaper and better, researchers say. Arnold Gillner, microtechnology head at the Fraunhofer Institute for Laser Technology in Germany, said: "Lasers work quickly, precisely, and without contact.
Artificial ovary 'turns immature human egg into mature one'May 8th, 2009 LONDON - An artificial ovary grown in lab by researchers at the Women and Infants Hospital in Providence, Rhode Island, has been able to turn an immature egg into one that is ready to be fertilised. Lead researchers Sandra Carson and Stephan Krotz had created the artificial ovary using slivers of ovarian tissue.
Scientists move step closer to creating artificial lifeMarch 12th, 2009 LONDON - US researchers have claimed that artificial life could be created "within five years."
Across the world laboratories are closing in on a "second genesis" - a breakthrough that would be one of the greatest scientific advancements of all time. According to Prof David Deamer, from California University, although making a new lifeform from scratch is a tough task he's confident it can happen in five to 10 years.
