+ - Perl is Undead!

Submitted by Ptolemarch
Ptolemarch (11506) writes "At the Yet Another Perl Conference beginning today in Orlando, the first keynote squarely blamed Slashdot for starting the "Perl is Dead" meme in 2005. He couldn't find the exact story he was thinking of, and, you know, neither can I, but let's be clear: if Perl was ever dead, it must now be undead. If you can't be at YAPC, you can still watch it live."

Creating "Homo Minutus" — a Benchtop Human To Test Drugs 49

Posted by Unknown Lamer
from the man-is-obsolete dept.
Science_afficionado (932920) writes "Vanderbilt University scientists reported significant progress toward creating 'homo minutus' — a benchtop human — at the Society of Toxicology meeting on Mar. 26 in Phoenix. The advance is the successful development and analysis of a human liver construct//organ-on-a-chip that responds to exposure to a toxic chemical much like a real liver. The achievement is the first result from a five-year, $19 million multi-institutional effort led by Los Alamos National Laboratory (LANL), to develop four interconnected human organ constructs — liver, heart, lung and kidney — that are based on a highly miniaturized platform nicknamed ATHENA (Advanced Tissue-engineered Human Ectypal Network Analyzer). The project is supported by the Defense Threat Reduction Agency. Similar programs to create smaller-scale organs-on-chips are underway at the Defense Advanced Research Projects Agency and the National Institutes of Health."

+ - The Earth is a gravitational wave detector->

But, physicist Freeman Dyson proposed back in 1969 that the earth itself could be used as a gravitational wave detector. The idea is behind the approach is that gravitational waves impact the earth’s crust, causing potentially detectable seismic waves. Using Dyson’s approach, Physicists at Harvard and NINP, Florence were able to put an upper limit on the intensity of gravitational background radiation based on a year of observational seismic data. The upper limit they found improved currently laboratory upper limits by 9 orders of magnitude."

Health insurance works more like the extended warranty I bought on my car. To add 4 years and and an extra 40000 miles to my cars warranty, it cost me $2,000. Car insurance of the normal type is about 800 per year for my car.

I am not sure I would call the extended warranty ridiculously expensive.

Normal Slashdot has a "disable ads" button if you have good karma. I believe that is what they are rederring to.

Indeed. That's Maker mode, as I mentioned, though Maker mode doesn't get offered for merely good karma.

I've implemented ad hiding for Maker mode, but if I can reproduce a bug with it, I'll fix it.

Solowheel is for People Who Think a Segway is Boring (Video) 94

Posted by timothy

Shane Chen is an inventor who likes to make all kinds of things. For instance, he designed the frame and invented a special reflective surface for the screen you see in the background of the video below. But many of his inventions have to do with transportation, especially the kind of transportation that doubles as personal thrill ride, like a sail for paddleboats and an electric surfboard. At this year's CES, I spoke with Chen's daughter Ywanne about his latest rideable invention, which is for obvious reasons called the Solowheel. Her father's the one you can see demonstrating the device in the background; you can see trickier riding in this YouTube video. She says that of all her father's inventions, this is the one that came together most easily: his first stab at a powered unicycle just worked, and since then it's been polishing the experience and getting it to market. And "to market" isn't a dream; for about $1800, you can have an experience that's a bit more intense than a Segway. The Solowheel can climb hills of surprising steepness, as long as the rider is up for it. Coming down looks more challenging, though.

Uni-Solar made some seriously crappy cells. If the plastic membrane on those cells got a scratch (and they scratched pretty easy) the cell would bloom into a rust ball that produced no power. Also the mounting adhesive could not handle multiple heating and cooling cycles without coming apart. The warranty department also had no idea how to fix the problems.

The problem with decriminalization as opposed to legalization, is that the supply chain is still unregulated. The upper chain are still criminals and can still adulter the product in dangerous ways. The product is still sold along side of harder drugs which is the mechanism for the gateway drug argument. And drug dealers exist outside of the law so there is no reason for them to not sell to children.
