Brain Mapping

The brain is the true Final Frontier, the most unknown part of the universe. But this still ain't it.

Brain Mapping

At the start of the 20th century, a German neuroanatomist named Korbinian Brodmann parceled the human cortex into nearly 50 different areas by looking at the structure and organization of sections of brain under a microscope. “That has been pretty much the reference framework that we’ve used for 100 years,” Evans says. Now he and his coworkers are redoing Brodmann’s work as they map the borders between brain regions. The result may show something more like 100 to 200 distinct areas, providing scientists with a far more accurate road map for studying the brain’s different functions.

Ultraprivate Smartphones

I guess we live in the Snowden era.

Ultraprivate Smartphones

Mobile phones for the consumer market that transmit minimal personal information. ... On January 21 a text message flashed on phones held by the protesters thronging Kiev’s Independence Square. Ukraine’s president, Viktor Yanukovych, was then still clinging to power and brutalizing opponents. The message—from the number 111—read: “Dear subscriber, you are registered as a participant in a mass disturbance.” ...... the NSA gathers huge amounts of information from cloud computing platforms and wireless carriers, including the numbers ordinary people called and the times they called them. Not only could the government be watching you: so could websites, advertisers, and even retailers trying to track your movements within stores. Modern smartphones and the apps running on them are engineered to collect and disseminate enormous amounts of user data—such as location, Web browsing histories, search terms, and contact lists. ....... Traditional crypto required the parties in an encrypted conversation to possess the same unique decoding tool (or “key”). The new approach was fundamentally different: it involved two mathematically linked keys, one private, the other public. Suddenly, applications such as digital signatures became possible. You could use a private key to “sign” a document; later, anyone else could use the public key to verify that you were indeed the author.

The Blockchain: More Than About Money

The blockchain can be used for more than money. I think it could be a base for social networking, among other things.

Agricultural Drones

Manufacturing need not fear information technology. This is solid proof. I mean, if agriculture can do it. I think this is cowboy technology. Sheep farmers in Australia could put this to good use.

Agricultural Drones

Easy-to-use agricultural drones equipped with cameras, for less than $1,000. ..... using sensors and robotics to bring big data to precision agriculture. ..... a low-cost aerial camera platform ..... This low-altitude view (from a few meters above the plants to around 120 meters, which is the regulatory ceiling in the United States for unmanned aircraft operating without special clearance from the Federal Aviation Administration) gives a perspective that farmers have rarely had before. Compared with satellite imagery, it’s much cheaper and offers higher resolution. Because it’s taken under the clouds, it’s unobstructed ...... due largely to remarkable advances in technology: tiny MEMS sensors (accelerometers, gyros, magnetometers, and often pressure sensors), small GPS modules, incredibly powerful processors, and a range of digital radios. ..... Drones can provide farmers with three types of detailed views. First, seeing a crop from the air can reveal patterns that expose everything from irrigation problems to soil variation and even pest and fungal infestations that aren’t apparent at eye level. Second, airborne cameras can take multispectral images, capturing data from the infrared as well as the visual spectrum, which can be combined to create a view of the crop that highlights differences between healthy and distressed plants in a way that can’t be seen with the naked eye. Finally, a drone can survey a crop every week, every day, or even every hour. Combined to create a time-series animation, that imagery can show changes in the crop, revealing trouble spots or opportunities for better crop management. ......... a trend toward increasingly data-driven agriculture. ..... We expect 9.6 billion people to call Earth home by 2050. All of them need to be fed. ...... More and better data can reduce water use and lower the chemical load in our environment and our food. Seen this way, what started as a military technology may end up better known as a green-tech tool, and our kids will grow up used to flying robots buzzing over farms like tiny crop dusters.
