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, [...]

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 [...]

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 [...]

In Popular Mechanics, longtime Foresight friend Prof. Glenn Reynolds looks at the future of nanotech and artificial intelligence, among other things looking at safety issues, including one call that potentially dangerous technologies be relinquished. He takes a counterintuitive stance, which we’ve discussed here at Foresight over the years: But I wonder if that’s such a [...]

Ted Greenwald posted yesterday at Wired about Foresight member Ralph Merkle’s presentation on nanotechnology at the Singularity University’s first Executive Program, which has just convened over at NASA Ames here in Silicon Valley: From there he skims through a catalog of progress — familiar example of pushing atoms into IBM logos and such on a [...]

Nanotechnology Enables Real Atomic Precision is the title of a piece by Susan Smith in Desktop Engineering, which includes comments by longtime Foresight Senior Associates Steve Vetter and Tihamer Toth-Fejel: While nanotechology might mean different things to different people, the term was originally coined to describe the building of things from the bottom up with [...]

From PhysOrg: … Implants and scaffolding for tissue growth require porous, soft materials — which are usually very fragile. Because many biological tissues are regularly subjected to intense mechanical loads, it is also important that the implant material have comparable elasticity in order to avoid inflammation. At the same time, the material must be very [...]

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 [...]
