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

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."

Submission + - The Earth is a gravitational wave detector (aps.org)

b30w0lf writes: Gravitational wave detection—i.e. the detection of propagating ripples in spacetime—is a hot subject these days with ground-based interferometer experiments like LIGO active, and hopes for a space interferometer like LISA. 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.

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.

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

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.

An Easy Way To Curb Smart-Phone Thieves, In Australia 234

First time accepted submitter xx_chris writes "Cell carriers can and do brick jail broken cell phones but they won't brick stolen cell phones. Except in Australia. The Australians apparently have been doing this for 10 years and it reduces violent crime since the thieves know they won't be able to sell the stolen phone. The article points out that cell carriers have a financial disincentive to do this since a stolen phone means another sale."
