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 [...]
The Mark, “Canada’s daily online forum for news, commentary, and debate,” has published a commentary that primarily takes a negative view of the use of nanotech (or any tech) for life extension: Extreme life extension raises other interesting, yet troubling questions. Significant life extension could have serious implications for individual identity; what if we change [...]
In the mailbag today: A new fiction book Beyond Guilty by Richard Brawer, who got help on it from Robert Freitas, winner of the 2009 Foresight Institute Feynman Prize for Theory. Brawer wrote, “Robert A. Freitas Jr., Senior Research Fellow at the Institute for Molecular Manufacturing, has graciously edited the references to nanomanufacturing and nanomedicine [...]
The March 2010 issue of IEEE Spectrum has an article on cryonics, a method of suspended animation, featuring Dr. Ralph Merkle. Ralph is described as a nanotechnology expert; apparently the issue went to press just before he was also named as a co-winner of the 2010 IEEE Haming Medal. As a long-time IEEE member, I [...]
Longtime readers know that we at Foresight would prefer that our members, and Nanodot readers in general, actually live long enough to experience the benefits of molecular nanotechnology personally. In that vein, we bring to your attention America’s Wellness Challenge, which I am helping as a member of their Social Media Advisory Board. If you [...]
Norman Borlaug: The Man Who Saved More Human Lives Than Any Other Has Died – (h/t Reason Magazine). Norman Borlaug, the man who saved more human lives than anyone else in history, has died at age 95. Borlaug was the Father of the Green Revolution, the dramatic improvement in agricultural productivity that swept the globe [...]
A nanotech-based gene-therapy method that dramatically improved the efficiency of conventional cancer therapy in animal models is now undergoing clinical trials.
Using a magnetic bead to slowly pull a DNA molecule through a solid-sate nanopore looks promising as the basis for a very fast and efficient nanotech DNA sequencing method.
A Newsdesk feature by Kelly Morris titled “Nanotechnology crucial in fighting infectious disease” in the April 2009 issue of Lancet Infectious Diseases surveys some highlights in developing nanotech efforts to prevent, diagnose, and treat infectious diseases. Examples include detecting disease through lab-on-a-chip technology featuring cantilevers that move upon binding antigens and nanowires that detect current [...]
By joining an iron oxide nanoparticle bearing a tumor-specific antibody with a gold nanoparticle bearing an anti-cancer drug, scientists created a dumbbell-like nanotech vehicle that delivered the drug into breast cancer cells.
What forces are going to shape the world throughout the 21st century? A recent NYT bestseller, The Next 100 Years, by George Friedman, proposes a number of very interesting theories. Friedman is considered to be something of an intellectual maverick, contradicting the conventional wisdom at many points, and very insightful, since in many cases his [...]
Nanotech advances are leading toward bone implants that are are smart, multifunctional devices that will be capable of improved integration with surrounding bone tissue, and that will resist inflammation, bacterial growth, and the recurrence of bone cancer.
Another promising nanotech approach to harnessing the potential of siRNA molecules is to pack them on the surface of gold nanoparticles.
Plant viruses are a new addition to the long list of types of nanoparticles being investigated as next generation nanotech cancer therapies.
Nanotech may soon provide a solution for one of the more vexing problems in tissue engineering—how to control the differentiation of pluripotent or multipotent precursor cells into the specific cells needed to fix a specific problem.
In new variation of ways to use nanotech to treat cancer, scientists have shown that using a scorpion toxin to target nanoparticles to brain cancer cells depletes the amount on the cancer cell surface of a protein required to make the cells invasive. From the National Cancer Institute’s Alliance for Nanotechnology in Cancer “Toxin-nanoparticle combo [...]
