Scientists have successfully prompted parts of the body to generate new blood vessels with newly developed “nanoneedles”. Continue reading… “Nanoneedles paving the way for new regenerative medicine”
Stephen Hawking wants to stop the rise of the machines.
Stephen Hawking turned 71 on January 8th and has joined the board of an international think tank devoted to defending humanity from futuristic threats. The newly founded organization, the Cambridge Project for Existential Risk, researches existential threats to humanity such as extreme climate change, artificial intelligence, biotechnology, artificial life, nanotech, and other emerging technologies. Skype cofounder Jaan Tallinn and Cambridge professors Huw Price and Martin Rees founded the project in late 2012.
An international team of scientists have discovered and mined out a new type of magnetic bacteria.
Scientists have dentified, isolated and successfully grown a new kind of magnetic bug that could open the way to biotech and nanotech uses, reveals a study.
When will we reach an endpoint? The answer (after the jump) will surprise you
“When it comes to atoms, language can be used only as in poetry. The poet, too, is not nearly so concerned with describing facts as with creating images.” – Niels Bohr, recipient of the 1922 Nobel Prize in Physics
I’ve had this ongoing notion that researchers will soon reach the point of creating the ultimate small storage particle. In discussing this with some nanotech friends, they felt we may reach an endpoint when we get to the size of the electron. So I decided to run with that assumption and calculate out how long it would take, based on Moore’s Law, to reach a point where we are storing information on electrons.
Nanotechnology is a relatively new sector, and future growth is dependent largely on growing government support and heavy investments in R+D initiatives. Nanotechnology plays a central role is the development of desktop manufacturing, cellular repair, artificial intelligence, inexpensive space travel, clean + abundant energy, and environmental restoration. Global nanotechnology market is increasingly witnessing a move towards consolidation, as players reorient strategies and realign their businesses to better reflect the changing competitive dynamics, and remain viable and competitive in the maturing market.

Total geek view of concrete
This video takes you on a journey into the atomic composition of one of the most common man made substances in the world – concrete. Second video after the jump.
New research* shows that while engineered nanomaterials can be transferred up the lowest levels of the food chain from single celled organisms to higher multicelled ones, the amount transferred was relatively low and there was no evidence of the nanomaterials concentrating in the higher level organisms.
Beware of the hairy nanotubes, even though you can’t see them and have no idea where they might be
Certain types of carbon nanotubes could cause the same health problems as asbestos, according to the results of two recent studies. In one, published yesterday, tests in mice showed that long and straight multiwalled carbon nanotubes cause the same kind of inflammation and lesions in the type of tissues that surround the lungs that is caused by asbestos. The other study, also done in mice, showed that similar carbon nanotubes eventually led to cancerous tumors.
Nanomedical start-ups generate 77% of returns but get only 27% of investment
Venture capital (VC) firms invested $702 million in nanotechnology start-ups last year across 61 deals, slightly down from $738 million across 73 deals in 2006. But this VC spending is sharply out of sync with investment returns. Although application-oriented life-sciences companies have delivered the majority of VC returns in nanotech, VC firms consistently devote most of their funding to companies in other areas, according to a new report from Lux Research entitled “How Venture Capitalists Are Misplaying Nanotech.”
New gauze material is infused with nanoparticles to quickly stop bleeding
Medical gauze has received its first upgrade since World War I. Chemists have infused it with nanoparticles derived from kaolin clay, which somehow give it an amazing ability to stop severe bleeding. It was developed when the Navy approached a team of inorganic chemists at the University of California Santa Barbara to solve a problem with QuikClot, a zeolite-based hemostatic agent that became way too hot and caused burns when it came in contact with water or blood. While performing blood clotting tests, they realized that kaolin clay, which has been used as a control for clotting experiments since the 1950’s, could also be used as a first aid product.
The US Military believes that humans will someday be able to regrow their limbs much like reptiles
The Department of Defense has announced the creation of the Armed Forces Institute of Regenerative Medicine to ‘harness stem cell research and technology… to reconstruct new skin, muscles and tendons, and even ears, noses and fingers.’ The government is budgeting $250 million in public and private money for the project’s first five years, and the NIH and three universities will be on the team.
An international team of astronomers has found 10 new “extra solar” planets, planets that orbit stars other than our sun.
