Irradiation with two wavelengths of visible light switches the position of a nitrogen atom close to a nickel ion, and in the process switches the magnetic state of the nickel ion.

Sixteen-year-old nanotechnologist Amy Chyao won top prize at the 2010 Intel International Science and Engineering Fair for her work on a nanoparticle to attack cancer cells and joined three other winners in Michelle Obama’s box during the State of the Union speech.
A new laser for nanotechnology could lead to more powerful microscopes, faster computers, and more efficient solar energy collectors.
Robert A. Freitas Jr. has made available his chapter on nanorobotics from the book The Future of Aging.
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.
Gold nanoparticles carrying nucleic acids into a cell must have the nucleic acids tightly linked via covalent bonds to avoid profound, unanticipated effects on gene expression.
Hogg and Freitas provide a theoretical analysis of the power constraints when nanorobots rely entirely on ambient bloodstream oxygen and glucose and identify aspects of nanorobot design that significantly affect available power.
Self assembly of aromatic dipeptide into nanospheres stiffer than Kevlar may make possible printing stronger, lighter body armor.

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 [...]
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 [...]
Our friends over at Singularity University are described in some detail in a long article in the New York Times. An excerpt, with names familiar to Nanodot readers as speakers at Foresight conferences: Some of Silicon Valley’s smartest and wealthiest people have embraced the Singularity. They believe that technology may be the only way to [...]
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 [...]
