Tiny brains created from SKIN could lead to cures for disorders like schizophrenia and autism Scientists used stem cells to grow 3D tissue that mimics a brainThe cells displayed an organisation similar to that seen in the early stages of the developing human brain's cerebral cortex - also known as grey matterThe miniature brains helped the researchers identify a defect that affects normal brain development in microcephaly leading to a smaller brainThe findings could eventually lead to treatments for other neurological disorders By Emma Innes Published: 18:19 GMT, 28 August 2013 | Updated: 00:00 GMT, 29 August 2013 A ‘brain in a bottle’ has been grown by stem cell scientists who hope it will lead to treatments for neurological and mental diseases. The ‘organoids’, three to four millimetres across, have a structure similar to that of an immature human brain.
Easy and effective therapy to restore sight: Engineered virus will improve gene therapy for blinding eye diseases Researchers at UC Berkeley have developed an easier and more effective method for inserting genes into eye cells that could greatly expand gene therapy to help restore sight to patients with blinding diseases ranging from inherited defects like retinitis pigmentosa to degenerative illnesses of old age, such as macular degeneration. Unlike current treatments, the new procedure is quick and surgically non-invasive, and it delivers normal genes to hard-to-reach cells throughout the entire retina. Over the last six years, several groups have successfully treated people with a rare inherited eye disease by injecting a virus with a normal gene directly into the retina of an eye with a defective gene. Despite the invasive process, the virus with the normal gene was not capable of reaching all the retinal cells that needed fixing.
Columbia Engineers Prove Graphene is Strongest Material July 21, 2008 Columbia Engineers Prove Graphene is the Strongest Material Research scientists at Columbia University’s Fu Foundation School of Engineering and Applied Science have achieved a breakthrough by proving that the carbon material graphene is the strongest material ever measured. Graphene holds great promise for the development of nano-scale devices and equipment. It consists of a single layer of graphite atoms arranged in a hexagonal lattice, similar to a honeycomb.
Nanotechnology is coming by Ralph C. Merkle, Principal Fellow, Zyvex This is the English original of an article translated into German and published in the Frankfurter Allgemeine Zeitung of Monday, September 11 2000 on page 55. In the coming decades nanotechnology could make a supercomputer so small it could barely be seen in a light microscope. Nanotechnology News - Nanoscience, Nanotechnolgy, Nanotech News Biofilms—the eradication has begun Have you ever heard of biofilms? They are slimy, glue-like membranes that are produced by microbes, like bacteria and fungi, in order to colonize surfaces. They can grow on animal and plant tissues, and even inside the human ...

Tiny buckyballs squeeze hydrogen like giant Jupiter (3/21/2008) Carbon cages can hold super-dense volumes of nearly metallic hydrogen Hydrogen could be a clean, abundant energy source, but it's difficult to store in bulk. In new research, materials scientists at Rice University have made the surprising discovery that tiny carbon capsules called buckyballs are so strong they can hold volumes of hydrogen nearly as dense as those at the center of Jupiter. The research appears on the March 2008 cover of the American Chemical Society's journal Nano Letters. "Based on our calculations, it appears that some buckyballs are capable of holding volumes of hydrogen so dense as to be almost metallic," said lead researcher Boris Yakobson, professor of mechanical engineering and materials science at Rice. "It appears they can hold about 8 percent of their weight in hydrogen at room temperature, which is considerably better than the federal target of 6 percent."
Cyborg snail gets biofuel cell implant The cyborg snail with a biofuel cell implant that generates electrical power from glucose and oxygen in the snail's blood Earlier this year we reported that researchers had implanted a cockroach with an enzyme-based biofuel cell that could potentially be used to power various sensors, recording devices, or electronics used to control an insect cyborg. While it may not be the most dynamic of creatures, a team from Clarkson University has now performed a similar feat with a living snail. The biofuel cell implanted into the snail by a team led by Evgeny Katz, the Milton Kerker Chaired Professor of Colloid Science at Clarkson University, was able to operate continuously producing electrical power for most of the snail's six month lifespan, using only the snail’s physiologically produced glucose and oxygen in the snail’s blood as a fuel. The team says the implanted biofuel cell would be able to operate in a natural environment, making it suitable for powering various bioelectronics devices.
