#Decoys could blunt spread of ash-killing beetlesas the emerald ash borer ravages North american ash trees threatening the trees'very survival a team of entomologists
Emerald ash borers (EABS) a type of beetle native to Asia first appeared in the U s. about 20 years ago.
They are now moving east from Michigan killing ash trees on the Eastern Seaboard as far south as North carolina.
Within 25 years practically no ash trees may remain on either side of the St lawrence Seaway said Akhlesh Lakhtakia Charles Godfrey Binder Professor of Engineering science and Mechanics at Penn State.
As their name implies emerald ash borers are iridescent green. The beetles don't carry disease
but their larvae feed on the ash trees'sap effectively killing the trees by depriving trees of their nourishment.
Thomas C. Baker Distinguished Professor of Entomology at Penn State knew that the male EAB locates a mate by flying over an ash tree finding a female by identifying her green wings
The researchers were able to create a color similar to the emerald ash borer's green wings by layering different types of polymer.
They also ran a pilot test in Hungary with a related beetle pest that bores into oak trees.
so that populations of emerald ash borers can be detected in new locations quickly paving the way for efficient use of other control methods according to the researchers.

#Femme fatale emerald ash borer decoy lures, kills malesan international team of researchers has designed decoys that mimic female emerald ash borer beetles
and successfully entice male emerald ash borers to land on them in an attempt to mate only to be electrocuted
According to the Forest Service the emerald ash borer was introduced to the United states from China in 2002.

and 3d printed decoys as well as dead female emerald ash borers onto leaves in forests in Hungary to see which of them best attracted wild males.
Ultimately we have gained new insights into how to manipulate the behavior of emerald ash borers
The researchers said their next step will be to further improve the traps to maximize their potential as part of an early detection tool for emerald ash borers.
and we will be working to couple this research with our ash-borer detection technique so that activity of the pest can be reported
of which are aggressive feeders on oak trees in Central europe and might threaten North american oaks in urban
and forest landscapes much as the emerald ash borer destroyed ash trees. We have made progress in our research so far in Hungary these past few summers
and it looks like our decoys can be refined to attract and detect these other new and potentially invasive pest species effectively said Domingue.

#Advantages, potential of computer-guided spinal surgeryin a series of research studies Cedars-Sinai spinal surgeons show that a new method of computer-guided spine surgery is beneficial for spinal reconstruction
The Cedars-Sinai surgeons highlight the advantages of a spinal navigation technique that uses high-speed computerized tomography (CT) imaging to navigate in and around the spinal column from different angles.
The Cedars-Sinai surgeons say they have cut these to nearly zero by using computer-guided methods.
This approach represents a major leap forward for instrumented spine surgery said Terrence T. Kim MD an orthopedic spine surgeon in the Cedars-Sinai Spine Center and expert in the computer-guided navigation field.
Johnson and Kim as study co-authors are Doniel Drazin MD a senior resident in the Department of Neurosurgery and Robert S. Pashman MD a clinical associate professor and orthopedic spine surgeon at the Cedars
One of the Cedars-Sinai studies showed that the mobile CT-scanner and computer-aided system used during minimally invasive surgery increased the accuracy of screw placement into vertebral pedicle bones.

while generating useful end products both in developing and developed nations said Linden. Since the 2012 grant Linden and his CU-Boulder team have received an additional $1 million from the Gates Foundation for the project
which includes a team of more than a dozen faculty research professionals and students many working full time on the effort.
Linden's team is one of 16 around the world funded by the Gates Reinvent the Toilet Challenge since 2011.
fibers said Linden. The energy generated by the sun and transferred to the fiber-optic cable system--similar in some ways to a data transmission line--can heat up the reaction chamber to over 600 degrees Fahrenheit to treat the waste material disinfect pathogens in both feces and urine and produce char.
Biochar is a valuable material said Linden. It has good water holding capacity and it can be used in agricultural areas to hold in nutrients
Linden is working closely with project co-investigators Professor R. Scott Summers of environmental engineering and Professor Alan Weimer chemical and biological engineering and a team of postdoctoral fellows professionals
We are doing something that has never been done before said Linden. While the idea of concentrating solar energy is not new transmitting it flexibly to a customizable location via fiber-optic cables is the really unique aspect of this project.
and moving parts and electrical engineers to design control systems Linden said. Tests have shown that each of the eight fiber-optic cables can produce between 80 and 90 watts of energy meaning the whole system can deliver up to 700 watts of energy into the reaction chamber said Linden.
In late December tests at CU-Boulder showed the solar energy directed into the reaction chamber could easily boil water
The great thing about the Gates Foundation is that they provide all of the teams with the resources they need Linden said.
Linden who called the 16 teams a family of researchers said the foundation has funded trips for CU-Boulder team members to collaborate with the other institutions in places like Switzerland South africa and North carolina.

Finally they studied the engineering results across hundreds of evolutionary trees of the bats to uncover the three optimal snout shapes favored by natural selection.
By coupling a flexible engineering model with analyses based upon evolutionary trees the study opens the possibility of discovering evidence for selection in other very diverse organisms
It also highlights the growing role of evolutionary trees in testing longstanding hypotheses on adaptation that could not be tested even ten years ago and certainly not without the engineering model.

There are kiosks that identify us by our palms, check out our library books and even make pizza with customized toppings.
Briggo produces organic coffee (using fresh, hormone-free milk and natural syrups) with a precision and consistency wholly unattainable by humans.
So just when we thought the coffee market was saturated, Briggo is filling a void--one that serves the coffee drinker who wants to use smart technology for a high-end, mobile-friendly coffee experience.
And the fully caffeinated Briggo team is thinking big. We â¢re not talking 10 to 20 kiosks
Yet even then, he expects Briggo to capture only a few percentage points of the coffee market.
Disrupting the coffee routine I visited Briggo early this year, at the end of student break, so the student center was quiet.
Still, customers occasionally wandered over to the kiosk to pick up their pre-ordered coffee drinks.
There are a half dozen traditional places to get coffee within about a five-minute walk of the Briggo kiosk.
First, a gourmet coffee company Mason handed me my chai, made from organic Pacific soy milk and organic Third street chai from Colorado.

If the price of specialty coffee is lower the benefit is purely financial, he said.
It will provide a great cup of coffee to the world while saving on employee costs.
Nahmias is no stranger to food robots. He grew up in Mexico city, and his private school had a French fry machine.
but he said there's something special about the human touch with coffee. People like to go in

And Nahmias thinks Briggo could be successful in regions of the country that have high uses of mobile technology

creating a way for customers to still have their morning coffee and conversation. And just like the neighborhood barista, the robot remembers what they like.
