Climategate, or, how science works

“Science advances, funeral by funeral.” (often attributed to Timothy Ferris) The blogosphere has been abuzz over the past week or so with the release of data — emails and program source and documentation — from the Climatic Research Unit at the University of East Anglia, one of the premier climatology research institutions in the world.… Continue reading Climategate, or, how science works

A molecular machine in action

From the protein crystallography beamline at Berkeley Labs Advanced Light Source: an action shapshot the Rho transcription factor from E. coli. The orange spiral in the middle is a strand of RNA, and Rho is everything else.   (http://www.youtube.com/watch?v=UPQ0OnlfkkA) (h/t Technology Review blog)

Peptides control crystal growth with switches, throttles and brakes

Peptides control crystal growth with switches, throttles and brakes. From Physorg.com.     (PhysOrg.com) — By producing some of the highest resolution images of peptides attaching to mineral surfaces, scientists have a deeper understanding how biomolecules manipulate the growth crystals. The research, which appears in the Nov. 23 online edition of the journal Proceedings of… Continue reading Peptides control crystal growth with switches, throttles and brakes

Foresight 2010: the Synergy of Molecular Manufacturing and AGI

This year is the 20th anniversary of the original Foresight Conference on Nanotechnology. The neat, clear vision of nanotechnology we had in 1989 rested on two key aspects that would make it a transformative, rather than merely an evolutionary, technology: The ability to construct and observe at the atomic scale, and the construction of machines… Continue reading Foresight 2010: the Synergy of Molecular Manufacturing and AGI

Reynolds advocates faster nano/AI R&D for safety reasons

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… Continue reading Reynolds advocates faster nano/AI R&D for safety reasons

Nano PVs: cheaper or better?

Over at Nanoclast, Dexter Johnson writes: It seems when nanotech is applied to photovoltaics it can either boost their efficiency to new heights or it can cheapen their manufacturing process. But it never seems to provide a solution to both of these. It’s always a tradeoff: increased efficiency but difficult manufacturing processes or a cheaper… Continue reading Nano PVs: cheaper or better?

Gallery – A joyride through the nanoscale – Image 1 – New Scientist

Gallery – A joyride through the nanoscale – Image 1 – New Scientist. This New Scientist article has some nice images from Whitesides recent book, sort of a retake on the “Secret House” idea.  

Technology Review: Self-Cleaning, Super-Absorbant Solar Cells

Technology Review: Self-Cleaning, Super-Absorbant Solar Cells. Amorphous-silicon solar cells patterned with nanoscale domes absorb more light–and shed water and dust.  

Moore's Law Marches On

According to the loose length-scale based definition, nanotechnology has long since conquered the world: feature sizes in microprocessors have been below the 100 nanometer mark for some time, qualifying them, if anyone wanted to, to be called nanoprocessors. The latest reports and plans are mentioning 22-nanometer parts just 2 years from now: DailyTech – AMD… Continue reading Moore's Law Marches On

More Merkle at Singularity University

Ted Greenwald continues his Singularity University executive program coverage over at Wired: These days, though, Merkle is setting his sights much higher. Over the past few years he has put together a theoretical system for building diamond, atom by atom. It involves nine molecular tools and methane/hydrogen feedstock on a diamond substrate. He has analyzed… Continue reading More Merkle at Singularity University
