#IBM's Watson Made Me A Kebabyou've probably heard of Watson IBM's super-intelligent supercomputer that dominated on Jeopardy!
not too long ago. Turns out he's not a bad cook either. At South By Southwest IBM has set up a food truck staffed with chefs from the Institute of Culinary Education who are whipping up (strange uncanny surprisingly tasty) daily recipes dreamed up by the machine.
Here's the background. For about two years IBM has been working on a way to harness Watson's data-driven computing into more creative fields--the kinds of things where unlike a game show there's no one right answer.
The first experiment with that has been in the kitchen. By mining a database of freely available online recipes (as well as recipes from professional chefs
and a molecular textbook) and estimating which ingredients might combine for a dish pleasing to a human palate Watson has been creating unlikely culinary works.
and tastiness the company designed an app that can make logical decisions on what might make for a good dish.

#The Garbage Manin December 2001 American environmental activist Jim Puckett traveled to the town of Guiyu in southeast China to look for old computers.
Towering piles of monitors printers and fax machines lined streets and occupied front yards. In a neighboring village women cooked circuit boards curbside in woks and children played atop ash heaps.
Puckett met people blackened head-to-toe with printer toner. Villagers explained that Guiyu now specialized in recycling electronics
In a village dedicated to plastics recycling Puckett found young women sitting on a concrete floor bashing computer housing to pieces with hatchets.
Puckett works for Basel Action Network (BAN) a group that monitors the export of hazardous waste.
While a small percentage of mixed plastics were cycled down from high-end products like computers to low-end goods like flowerpots

Biddle could take the plastic from say a laptop reduce it to its purest form

In 1992 the American Plastics Council funded him to research the recycling of computer plastics.
Was it more efficient to separate bulky computer components from one another or was it better to shred everything first?
but he d succeeded in selling some recycled plastics back to IBM. We could look at a molded section
if you shredded everything before separation you could deal with volume through automation. I said You re joking Mann recalls.
Several weeks later we chat on the phone and Biddle talks about a development that makes him more optimistic than the promises of British politicians.
Today that s all done by computer. An architect designs a building using 3-D Autocad software
and the program generates the material specs and sends them to robotic wood or steel routers
Slowly though developers are coming around particularly those that grasp the economic benefits of building with CLT.
But the biggest driving force behind the turn toward wood is a growing awareness among architects and developers about their field s contribution to climate change.

#New approach to vertex connectivity could maximize networks bandwidthtechnique advances understanding of a basic concept in graph theory paralleling advances in edge connectivity.
Computer scientists are constantly searching for ways to squeeze ever more bandwidth from communications networks. Now a new approach to understanding a basic concept in graph theory known as vertex connectivity could ultimately lead to communications protocols--the rules that govern how digital messages are exchanged--that coax as much bandwidth as possible from networks.
Graph theory plays a central role in mathematics and computer science and is used to describe the relationship between different objects.
Each graph consists of a number of nodes or vertices which represent the objects and connecting lines between them known as edges
which signify the relationships between them. A communications network for example can be represented as a graph with each node in the network being one vertex
and a connection between two nodes depicted as an edge. One of the fundamental concepts within graph theory is connectivity
which has two variants: edge connectivity and vertex connectivity. These are numbers that determine how many lines
In this way both concepts show how robust a network is against failure and how much flow can pass through it
--whether the flow of information in a communications network traffic flow in a transportation system or fluid flow in hydraulics. Reducing edge connectivity's edgehowever while a great deal of research has been carried out in mathematics to solve problems associated with edge connectivity there has been relatively little success in answering questions about vertex connectivity.
But at the ACM-SIAM Symposium on Discrete Algorithms in Portland Ore. in January Mohsen Ghaffari a graduate student in the Computer science and Artificial intelligence Laboratory at MIT will present a new technique for addressing vertex-connectivity problems.
This could ultimately help us understand how to build more robust and faster networks says Ghaffari who developed the new approach alongside Keren Censor-Hillel at the Technion and Fabian Kuhn at the University of Freiburg.
If a network contains three edge-disjoint spanning trees for example information can flow in parallel along each of these trees at the same time meaning three times more bandwidth than would be possible in a graph containing just one tree.
In graph theory a group of nodes is called a connected dominating set if all of the vertices within it are connected to one another
and then passed to any other node in the network. So in a similar way to Tutte and Nash-Williams'results for edge connectivity each graph contains almost as many vertex-disjoint connected dominating sets as its vertex connectivity Ghaffari says.
So if you think of an application like broadcasting information through a network we can now decompose the network into many groups each being connected one dominating set he says.
The team has developed now an algorithm that can carefully decompose a network into many connected dominating sets.
In this way it can structure so-called wireless ad hoc networks in which individual nodes route data by passing it from one to the next to ensure the best possible speed of information flow.
We want to be able to spread as much information as possible per unit of time to create faster and faster networks Ghaffari says.
Applications in assessing robustnessthe researchers can also use their new approach to analyze the robustness of a network against random failures.
whether a network is likely to remain connected when its nodes fail randomly with some given probability Ghaffari says.
Noga Alon a professor of mathematics and computer science at Tel aviv University says Ghaffari and his fellow authors have identified the notion that determines the largest achievable flow
when broadcasting messages using routing in communication networks. The investigation of this notion vertex disjoint connected dominating sets is treated in this paper by an elegant combination of combinatorial probabilistic and algorithmic techniques he says.

These toxins were isolated from the bacterium Bacillus thuringiensis (Bt. These Bt corn hybrids have been adopted widely because they are exceptional for managing ECB--99.9 percent of larvae are expected to die
when they feed on plants expressing Bt toxins he said. Yet a drawback to using these hybrids has been the high cost of purchasing the seeds
which can decrease potential profits. To understand current ECB populations in Pennsylvania field corn the researchers assessed larval damage in Bt and non-Bt corn hybrids at 29 sites over three years.
Specifically they planted Bt and non-Bt corn hybrids on farm sites across four growing zones in Pennsylvania in 2010 2011 and 2012.
During September of each season they assessed corn borer damage on 400 random plants at each site.
They sliced open stalks and recorded the number of ECB tunnels and larvae per stalk.
With less ECB damage around non-Bt hybrids in our tests yielded just as well as Bt hybrids so the decline in ECB populations provides an opportunity for growers to generate greater profits by planting high-yielding non-Bt seed
which is much cheaper than Bt seed. Secondarily planting more non-Bt corn will reduce the potential for ECB to develop resistance to Bt toxins as corn rootworms have done in about a dozen states so far.
The team's results appeared in an early online edition of the journal Pest Management Science in December.
In addition to investigating the extent of ECB populations and damage in Pennsylvania the researchers also examined the predictive ability of the Pestwatch network
which traps ECB and other moth species and provides data about their prevalence. While traps within the Pestwatch network provide insight on ECB population size where moths are active
and periods of ECB activity their utility as a predictive tool particularly for field corn has been limited Bohnenblust said.
We found that ECB moths captured in the Pestwatch network correlate well with in-field populations of ECB in field corn which means that Pestwatch data hold potential to inform decisions about
whether Bt or non-Bt hybrids are right for growers in different parts of the state.
According to Tooker growers planting Bt corn hybrids are required to plant set amounts of non-Bt corn as part of a resistance management plan to help prevent evolution of ECB populations that are resistant
to the Bt toxins expressed in corn hybrids. Based on our results we would tell growers to scout their non-Bt acreage toward the end of the growing season he said.
If they have low ECB populations and Pestwatch reflects low moth captures in their area we would recommend that in the next season they give competitive non-Bt hybrids a try on some of their acres
because they could see better profits from growing non-Bt hybrids. Story Source: The above story is provided based on materials by Penn State.
