The Plants' Internet: The Wood Wide Web

Who could have thought!
Hidden under your feet is an information superhighway that allows plants to communicate and help each other out. It’s made of fungi ........ That tree in your garden is probably hooked up to a bush several metres away, thanks to mycelia. ..... They aren't just sitting there quietly growing. By linking to the fungal network they can help out their neighbours by sharing nutrients and information – or sabotage unwelcome plants by spreading toxic chemicals through the network. This "wood wide web", it turns out, even has its own version of cybercrime. ..... Simply plugging in to mycelial networks makes plants more resistant to disease. ..... mycorrhizae also connect plants that may be widely separated. ..... similarities between mycelia and ARPANET, the US Department of Defense's early version of the internet. ..... James Cameron's 2009 blockbuster Avatar. On the forest moon where the movie takes place, all the organisms are connected. They can communicate and collectively manage resources, thanks to "some kind of electrochemical communication between the roots of trees". ..... large trees help out small, younger ones using the fungal internet. .... when plants are attached by harmful fungi, they release chemical signals into the mycelia that warn their neighbours. ..... broad beans also use fungal networks to pick up on impending threats – in this case, hungry aphids. ...... plants' fungal connections mean they are never truly alone, and that malevolent neighbours can harm them. ...... some plants steal from each other using the internet. There are plants that don't have chlorophyll ..... plant cybercrime can be much more sinister than a bit of petty theft. ...... spotted knapweed, slender wild oat and soft brome can all change the fungal make-up of soils. According to Morris, this might allow them to better target rival species with toxic chemicals, by favouring the growth of fungi to which they can both connect. ...... The wood wide web

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.

Google Fiber To Google Wireless



Google Australia’s Engineering Director Explains Why We Don’t Need Google Fiber
Alan Noble is the engineering director of Google Australia, and he says that there’s absolutely no need for Google Fiber Down Under. .... Noble said that there was just no need for Google to become an ISP in Australia because eventually, everyone would have Gigabit speeds .... In theory, the NBN should fulfill that need in Australia. Restricting the NBN to 100Mbps speeds is purely a commercial decision, not a technical one. There is no technical reason the NBN could not run at Gbps speeds
When I read the headline I thought the guy might say there is no need for fiber, wireless is the better option. But he did not say that.

Brazil: The Largeness Of A Country


Some countries are huge geographically but minuscule in population: Canada, Russia, Australia. Brazil is not one of those. Its large presence on the map is matched by the people who populate that map.
