Single-atom sheet of carbon clears arsenic from water

Posted by Christine Peterson on July 15th, 2010

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 [...]

Today’s nanotech lets $400 camera see cancer cells

Posted by Christine Peterson on June 29th, 2010

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, [...]

Join us at Singularity Summit, Aug. 14-15 on intelligence augmentation

Posted by Christine Peterson on June 16th, 2010

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 [...]

H+ Summit “Rise of the Citizen Scientist” at Harvard

Posted by Christine Peterson on June 9th, 2010

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: [...]

Vote and comment on IMM/Foresight statement to President’s Council

Posted by Christine Peterson on June 1st, 2010

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 [...]

Nanotechnology and life extension: challenge & response

Posted by Christine Peterson on May 10th, 2010

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 [...]

New sf novel includes nanomedicine, reviewed by Robert Freitas

Posted by Christine Peterson on March 23rd, 2010

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 [...]

IEEE Spectrum looks at cryonics

Posted by Christine Peterson on March 18th, 2010

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 [...]

Life extension: taking those first steps

Posted by Christine Peterson on December 28th, 2009

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, R.I.P: The Man Who Saved More Human Lives Than Any Other Has Died

Posted by J. Storrs Hall on September 13th, 2009

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 [...]

Nanotechnology in clinical trials to restore normal gene function to cancer cells

Posted by Jim Lewis on April 24th, 2009

A nanotech-based gene-therapy method that dramatically improved the efficiency of conventional cancer therapy in animal models is now undergoing clinical trials.

Nanotechnology pulls DNA through nanopore slowly enough to read sequence

Posted by Jim Lewis on April 20th, 2009

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.

Promise of nanotechnology for fighting infectious diseases will balance public’s safety concerns

Posted by Jim Lewis on April 3rd, 2009

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 [...]

Nanotechnology targets cancer cells with dumbbell-like particles

Posted by Jim Lewis on March 23rd, 2009

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.

Required Reading

Posted by J. Storrs Hall on March 18th, 2009

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 [...]
