DNA nanotechnology provides cell-surface sensors for real-time monitoring of single cells, including potential use in personalized medicine to test which drugs would be suitable for which individuals.
A nanotechnology therapy using targeted dendrimers shows promise against head and neck cancer in experiments in which human tumors are implanted into immunocompromised mice.
The world’s first synthetic organ transplant was a replica windpipe made from a nanocomposite scaffold seeded with the patient’s own adult stem cells.
Carbon nanofibers and a polymer were combined to create a composite to regenerate natural heart tissue.
A poll of NewScientist readers selected medical nanorobots as the technology that will have the biggest impact on human life in the next 30 years.
‘Good Cholesterol’ nanoparticles are non-toxic and use the need of cancer cells for HDL cholesterol to deliver RNA molecules to silence the expression of cancer-promoting genes.
Novel biodegradable nanoparticles destroy membranes of drug-resistant ‘superbugs’ without harming blood cell membranes.
A cover article in Time magazine portrays the Singularity, Ray Kurzweil, AI, life extension, and nanotechnology as “an idea that rewards sober, careful evaluation.”
Catalytic nanomotors deliver nanoparticles containing drugs a thousand fold faster than do nanoparticles transported by Browninan motion.
Nanoparticles that deliver two anticancer agents simultaneously kill cancer cells more effectively than nanoparticles delivering the agents separately.
Humanity+ @ Caltech: Redefining Humanity in the Era of Radical Technological Change is being streamed live.
Redefining Humanity in the Era of Radical Technological Change, December 4-5, 2010, Pasadena, CA
Many of you have an interest in human longevity in general and in being healthier and living longer personally. If we want to help develop and guide nanotech and other advanced technologies, we need to stay healthy. I am organizing a conference on this topic, October 9-10, here in the Bay Area: http://lifeextensionconference.com You will [...]
The Open Science Summit on July 29-31 in Berkeley is looking better and better. Topics include OpenPCR, DIY biology, open source hardware, brain preservation, synthetic biology, gene patents, open data, open access journals, reputation engines, crowd-funding and microfinance for science, citizen science, biohacking, open source biodefense, cure entrepreneurs, open source drug discovery, patent pools, tech transfer, and [...]
We can get a hint of the power coming from longer-term nanotech by seeing what is being discovered today on how to use some of the new materials becoming available. Many of us have been intrigued with graphene, a one-atom-thick planar sheet of bonded carbon atoms. It’s no surprise that exciting applications are being found [...]
Frequent Nanodot readers know that our main interest is longer-term nanotech, but sometimes what’s happening today gets pretty exciting as well. A quick summary of recent advances in nanotech used to fight cancer appears in a Computerworld piece by Sharon Gaudin; some excerpts: Rice University said yesterday that when the nanoparticles deliver dye to the cell, [...]
Many Foresight leaders and members will be gathering at this year’s Singularity Summit in San Francisco, expected to draw up to 1100 participants. It’s a bit pricey, but it’s for a good cause and there are student and referral discounts plus discounts on the hotel rooms. I can testify that this is a fun and [...]
If you can’t make it to Harvard this weekend, June 12-13, you’ll want to catch the live webcast of the H+ Summit: “Rise of the Citizen Scientist”. No link yet, but presumably they’ll be putting it on the event homepage before it starts. Also presumably they will post the videos somewhere for longer-term viewing. UPDATE: [...]
The U.S. President’s Council on Advisors on Science and Technology requested public input on a number of manufacturing topics including “molecular-level, atomically precise production.” Foresight joined with our sister organization IMM to produce a statement on Atomically Precise Manufacturing, now posted on the OpenPCAST site, with public voting and commenting still continuing, so join in the [...]
