Automate the Freight: Amazon’s Robotic Packaging Lines
Posted by Quinn Sena in categories: biotech/medical, economics, habitats, robotics/AI
In the “Automate the Freight” series, I’ve concentrated on stories that reflect my premise that the killer app for self-driving vehicles will not be private passenger cars, but will more likely be the mundane but necessary task of toting things from place to place. The economics of replacing thousands of salary-drawing and benefit-requiring humans in the logistics chain are greatly favored compared to the profits to be made by providing a convenient and safe commuting experience to individuals. Advances made in automating deliveries will eventually trickle down to the consumer market, but it’ll be the freight carriers that drive innovation.
While I’ve concentrated on self-driving freight vehicles, there are other aspects to automating the supply chain that I’ve touched on in this series, from UAV-delivered blood and medical supplies to the potential for automating the last hundred feet of home delivery with curb-to-door robots. But automation of the other end of the supply chain holds a lot of promise too, both for advancing technology and disrupting the entire logistics field. This time around: automated packaging lines, or how the stuff you buy online gets picked and wrapped for shipping without ever being touched by human hands.

Defense against wireless attacks using a deep neural network and game theory
Posted by Saúl Morales Rodriguéz in categories: business, habitats, internet, mobile phones, robotics/AI, security
A growing number of devices are now connected to the internet and are capable of collecting, sending and receiving data. This interconnection between devices, referred to as the Internet of Things (IoT), poses serious security threats, as cyberattackers can now target computers and smartphones, but also a vast array of other devices, such as tablets, smart watches, smart home systems, transportation systems and so on.
For the time being, examples of large-scale IoT implementations (e.g. connected infrastructure, cities, etc.) are somewhat limited, yet they could soon become widespread, posing significant risks for businesses and public services that heavily rely on the internet in their daily operations. To mitigate these risks, researchers have been trying to develop security measures to protect devices connected to the internet from wireless network attacks.
To this end, two researchers at Baoji University of Arts and Sciences, in China, have recently developed a new method to defend devices in an IOT environment from wireless network attacks. Their approach, presented in a paper published in Springer’s International Journal of Wireless Information Networks, combines a deep neural network with a model based on game theory, a branch of mathematics that proposes strategies for dealing with situations that entail competition between different parties.

Ancient fungi may have laid the groundwork for complex life
Posted by Quinn Sena in categories: biotech/medical, habitats
But previous examination of the fungal “molecular clock,” using DNA-based methods, suggested that fungi may have evolved much earlier, between 760 million and 1.06 billion years ago. Extracted from Arctic Canadian shales, the newly discovered billion-year-old fossilized fungal spores and hyphae (long thin tubes) plug the gap in the fossil record and suggest that fungi may have occupied land well before plants.
The fungal fossils were found in rocks that were probably once part a shallow-water estuary. Such environments are typically great for fungi thanks to nutrient-rich waters and the build up of washed-up organic matter to feed on. The high salinity, high mineral and low oxygen content of these ancient coastal habitats also provided great conditions to perfectly preserve the tough chitin molecules embedded within fungal cell walls that otherwise would have decomposed.
While it’s not certain whether the newly-discovered ancient fungi actually lived within the estuary or were washed into the sediments from the land, they show many of the distinctive features you’d expect in modern terrestrial fungi. The germinating spores are clearly defined, as are the branching, thread-like tubes that help fungi explore their environment, named hyphae. Even the cell walls are distinctively fungal, being made up of two clear layers. In fact, if you didn’t know they were so old, you’d be hard-pressed to distinguish them from modern fungi.

The Astounding Engineering Behind the Giant Magellan Telescope
Posted by Genevieve Klien in categories: education, engineering, habitats, space
It’s easy to miss the mirror forge at the University of Arizona. While sizable, the Richard F. Caris Mirror Laboratory sits in the shadow of the university’s much larger 56,000-seat football stadium. Even its most distinctive feature—an octagonal concrete prominence emblazoned with the school’s logo—looks like an architectural feature for the arena next door. But it’s that tower that houses some of the facility’s most critical equipment.
Inside the lab, a narrow, fluorescent-green staircase spirals up five floors to the tower’s entrance. I’m a few steps from the top when lab manager Stuart Weinberger asks, for the third time, whether I have removed everything from my pockets.
“Glasses, keys, pens. Anything that could fall and damage the mirror,” he says. Weinberger has agreed to escort me to the top of the tower and onto a catwalk some 80 feet above a mirror 27.5 feet in diameter. A mirror that has already taken nearly six years—and $20 million—to make. “Most people in the lab aren’t even allowed up here,” he says. That explains Weinberger’s nervousness about the contents of my pockets (which are really, truly empty), and why he has tethered my camera to my wrist with a short line of paracord.

Researchers develop wood that can cool a home
Posted by Genevieve Klien in categories: habitats, materials
Wood has a series of tiny structures inside that are used to carry water and nutrients to all parts of a living tree. Scientists have now figured out how to harness those same small structures to keep a home cool. Researchers at the University of Maryland and the University of Colorado Boulder say that the material could save 20% in AC bills.

Cooling wood: Engineers create strong, sustainable solution for passive cooling
Posted by Paul Battista in categories: energy, habitats, nanotechnology, sustainability
What if the wood your house was made of could save your electricity bill? In the race to save energy, using a passive cooling method that requires no electricity and is built right into your house could save even chilly areas of the US some cash. Now, researchers at the University of Maryland and the University of Colorado have harnessed nature’s nanotechnology to help solve the problem of finding a passive way for buildings to dump heat that is sustainable and strong.

‘Like trying to build the USA in the middle of the Atlantic’: Elon Musk just dunked on Jeff Bezos’ vision to build floating space colonies

I agree with Bezos on this one.
Elon Musk dismissed Jeff Bezos’ plan of housing a trillion people in orbiting ‘O’Neill colonies,’ which resemble gargantuan spinning cylinders.
