New Metal-Air Transistor Replaces Semiconductors
A novel field emission transistor that uses air gaps could breathe life into Moore’s Law
when robots get sufficiently smart, they start to avoid work too 🙂
> CycleGAN learns to “hide” information about a source image into the images it generates in a nearly imperceptible, high frequency signal. This trick ensures that the generator can recover the original sample and thus satisfy the cyclic consistency requirement, while the generated image remains realistic

that's how NSA attacked SSH and HTTPS (most likely). it's so simple, as always. ingenious.
note: not applicable to bitcoin, the vulnerable spot here is key generation, not the math itself :)

The (Almost) Secret Algorithm Researchers Used to Break Thousands of RSA Keys
RSA encryption allows for anyone to send me messages that only I can decode. To set this up, I select two large random primes $latex p$ and $latex q$ (each of which is hundreds of bits long), and r…

Porphyromonas gingivalis in Alzheimer’s disease brains: Evidence for disease causation and treatment with small-molecule inhibitors
Porphyromonas gingivalis , the keystone pathogen in chronic periodontitis, was identified in the brain of Alzheimer’s disease patients. Toxic proteases from the bacterium called gingipains were also identified in the brain of Alzheimer’s patients, and levels…

Lessons learned building natural language processing systems in health care
NLP systems in health care are hard—they require broad general and medical knowledge, must handle a large variety of inputs, and need to understand context.
