Computer Modeling Provides more details for nanoscale

Taking issue with the perception that computer models lack realism, a Sandia National Laboratories researcher told his audience that simulations of the nanoscale provide researchers more detailed results — not less — than experiments alone Fang derided the pejorative “garbage in, garbage out” description of computer modeling — the belief that inputs for computer simulations …

other tech: Korean advance on reversing cellular senescence

As noted by Harold Brenner:The importance of recent Korean research on cell death1. Cellular Senescence is reversible2. DNA damage induces senescence3. Rather than interfering with the DNA damage signaling pathway we should be looking at increasing the rate and ability to repair DNA damage to bring about the reversal of senescence.

New paper posted at Eric Drexler’s site

The paper is Robust Composition: Towards a Unified Approach to Access Control and Concurrency Control by MS Miller. Drexler description of the paper and its significance: Describes how to structure object-oriented programming to enable software components to work together without mutual interference—a way to escape from fragile thread-based concurrency and the threat of viruses, and …

other tech: widespread stability control would save 10,000 lives in the US per year

A study from the Insurance Institute for Highway Safety said the technology, electronic stability control, reduced the risk of single-vehicle rollovers involving sport utility vehicles by 80 percent, and 77 percent for passenger cars. Rollovers are extremely dangerous, accounting for only 3 percent of all crashes but leading to more than 10,000 deaths (23% of …

Program automatically generates 3-D models from a single photograph

Generating a 3 dimensional model from a 2 dimensional picture could ultimately find application in vision systems used to guide robotic vehicles, monitor security cameras and archive photos. Using machine learning techniques, Robotics Institute researchers Alexei Efros and Martial Hebert, along with graduate student Derek Hoiem, have taught computers how to spot the visual cues …

Evidence of RNA in structures essential to cell division

There is now evidence for the first time that centrosomes, which play a key role in cell division, may carry their own genetic machinery, answering a controversial question of long standing. Using a technique he developed, Dr. Palazzo isolated relatively large quantities of centrosomes from the clam eggs. The Alliegros, using highly sophisticated techniques they …

Supercurrent in quantum dots and electron control in nanowires

Researcher have places quantum dots on semiconducting nanowire. He can achieve supercurrent in the dots. He can precisely control the electrons in the quantum dot using an external charge. Low temperature and pure nanowires are needed. Improved nanowire quality was also part of the research. Jorden van Dam, researcher at the Kavli Institute of Nanoscience …
