From EEtimes, Naval Research Laboratory (NRL) scientists will next month describe a technique that would allow spintronics to be inserted into the standard silicon CMOS processes using ferromagnetic materials similar to those already used for magnetic random access memory. Our demonstration showed a 30 percent polarization of the injected electrons, which is not bad considering …
Kurzweil AI points out a New York play about Eliezer Yudowski. It is called “Yudkowski Returns: The Rise And Fall And Rise Again of Dr. Eliezer Yudkowski,”. The play is reviewed positively here Eliezer Yudkowsky is a leading artificial intelligence researcher who is trying to develop Friendly AI. Brian WangBrian Wang is a Futurist Thought …
This pdf discusses a recent presentation by Geordie Rose, CTO of Dwave Systems The main thing is that Dwave believes that they are still on track to release a commercial system May, 2008 that will be one hundred times faster for certain business relevant problems. This would probably be the 512 qubit machine. The 1024 …
The NY Times reports that the cost of sequencing he human genome is down below $100,000 and that 1% of the genome that is considered the most relevant can be sequenced for $1000 By the end of the summer [2007], Dr. Church’s research project promises to deliver sequences to its first 10 volunteers. Unlike Dr. …
Nanowerk has a spotlight on artificial adjustable nanofluid channels Flow of fluorescein molecules through an array of five tunable elastomeric nanochannels and their accumulation at an air-filled microscale compartment. Running horizontally at the top is an air-filled microchannel. The nanochannels are triangular and are 80 nanometers high from base to top corner and 600 nm …
Loss of only one of the genes, a gene encoding the protein PHA-4, negated the lifespan-enhancing effect of calorie-restriction in worms. And, when researchers undertook the opposite experiment—by overexpressing pha-4 in worms—the longevity effect was enhanced. “PHA-4 acts completely independent of insulin/IGF-1 signaling and turns out to be essential for CR-mediated longevity,” says Panowski. “We …
Four 71-inch mirrors gathering light for Pan-STARRS would each be hooked up to what would be the four largest digital cameras ever built. The system would be able to survey the entire sky once a week, and would be able to detect asteroids as small as 1,000 feet across. They face opposition from environmentalists who …
From Biosingularity, and Canada’s National post, word of breakthrough near cure for diabetes In a discovery that has stunned even those behind it, scientists at a Toronto hospital say they have proof the body’s nervous system helps trigger diabetes, opening the door to a potential near-cure of the disease that affects millions of Canadians. The …
