#Nano web trips up bed bugs Stony Brook University Posted by James Montalto-Stony Brook on May 31 2013stony BROOK (US)# A new non-chemical solution literally stops bed bugs
The web consists of microfibers 50 times thinner than a human hair which entangle and trap bed bugs and other insects.#
Some of the photons are allowed to escape from the device to serve a purpose such as reading data off a CD or etching a circuit board.
Researchers conducted the work in collaboration with the National Institute of Informatics in Tokyo Japan and a team from the University of W##rzburg in Germany led by physicist Alfred Forchel.

The dynamo was developed through simulations using the high-performance computing facilities located at the University of Leeds.#The fact that it took 50 years
and huge supercomputers shows how complicated the dynamo process really is#says Professor Fausto Cattaneo of the University of Chicago#s department of astronomy and astrophysics.
At the core of the device is a nanoscale structure#about a tenth of a millimeter wide
which can lower the power consumption of the tiny chips used inside wearable devices by as much as 10 times in wake mode
It does this without requiring fancy changes in manufacturing or a new way of writing software

#Engineers have created a smartphone HIV test that costs $35 to make Let s be honest: Smartphones aren thought#t necessarily of as devices that help to slow the spread of sexually transmitted diseases.
In fact research has found that transmission rates go up when hookup sites#even ones on the tamer end like Craigslist#come to town.
But smartphones are also capable of transforming into competitive diagnostic tools as a team of biomedical engineers out of Columbia University is showing with their new attachment that can detect both HIV and syphilis in a single 15-minute test.
The dongle as the team writes in the journal Science Translational Medicine costs just $34 to make (an amount that could drop further if mass produced.
It uses the phone#s power and data collection and incorporates simple optics and fluid control to process a finger prick of blood.
While paper-based options for home testing do exist and work much in the way that a home pregnancy test does they are not nearly as sensitive
instead the end user pushes against a negative-pressure chamber to move the sequence of reagents onto the cassette.

#Autodesk is now selling an open-source 3d printer Autodesk first foray into hardware is here: The Ember 3d printer is now available for anyone to order.
At $5, 995, the printer isn exactly a steal. Autodesk more so built it to be the perfect exhibitor for its open-source Spark 3d printing software,
which is currently in beta. People married to Autodesk suite of software might find that pairing of interest,
but the greater 3d printing industry might buy Ember because Autodesk plans to release exactly how it is built
and operates. Makerbot, the best known desktop 3d printer brand, gave rise to an entire class of printers
because its first machines were similarly open source. Ember could do the same for a different desktop technology.
I had the chance to see Ember in action at Autodesk Pier 9 manufacturing space in San francisco. It a digital light processing machine,
which means it uses a projector similar to those found in those bulky classroom machines.
a necessary step in DLP printing. The Ember printer handles that last step in an unusual way.
The tank is shaped like a cashew; a half-instead of the square shape used by every other DLP printer.
After each layer is printed, the print platform raises slightly and the tank whips around the curve of the machine before returning to its home position.
Autodesk chose the unusual tank design because it requires the machine to use a lot less force, according to Autodesk 3d printing research scientist Andreas Bastian.
Each time the projector cures a layer, it creates a huge amount of suction between the 3d printed object and the bottom of the resin tank.
pending approval from the FCC. Autodesk has yet to release the actual open-source documentation for the machine,
but my personal run-in with the printer at Pier 9 was welcome confirmation that Ember really exists,

This may be about to change thanks to the Voxel8 a printer presented at CES that makes it much easier to blend plastic conductive ink
and other electronic components in the same object to manufacture highly customizable devices such as your very own quadcopter.
Special conductive inks and the right kind of printers already make it possible to build simple parts with embedded electronics.
The idea is that this new ink will enable users to easily wire together chips
Thanks to its unique software (which was developed specifically by CAD software giant Autodesk and is hosted in the cloud) the printing can also pause at predetermined points
so that users can manually insert the components that will be embedded in their 3d printed objects. As printers go this one appears to be on the higher end of the spectrum with features including a 4. 3-inch touchscreen USB
and Wi-fi connectivity and a kinematically coupled bed that uses magnets to ensure high-precision printing even after the various components are inserted manually.
The XY resolution is 15 microns layer resolution is 200 microns and the device can reportedly print objects up to 4 x 6 x 4 inches (10 x 15 x 10 cm) in size.
The only two printing materials currently supported are standard PLA plastic and the silver conductive ink but the startup has said users will be able to upgrade their printer in the future as more functional
and matrix materials are released. Voxel8 printers are set to begin shipping late this year. The US$8999 standard price tag includes two PLA filament spools and five conductive ink cartridges.
Should you choose to pre-order which entails a $500 deposit you'll get double the printing materials.

#Abusive Spouses are Using Spyware to Track their Victims The use of surveillance software by abusive spouses to monitor the phones
and computers of their partners secretly has reached pidemic proportionsand police are ill-equipped to tackle it,
Helplines and women refuge charities have reported a dramatic rise in the use of spyware apps to eavesdrop on the victims of domestic violence via their mobiles and other electronic devices,
The Independent has established that one device offering the ability to spy on phones is being sold by a major British high-street retailer via its website.
The proliferation of software packages, many of which are marketed openly as tools for covertly tracking a heating wife
or former partner, using Christmas or birthday presents such as phones, computers and toys pre-loaded with spyware to infiltrate a target home.
Polly Neate, chief executive of Women Aid, told The Independent: omestic abuse is about control and perpetrators will use any means available to maintain
and increase their control. e increasingly hear stories of abusers adding tracking software to phones,
placing spyware on personal computers and using the internet to gather information about their partner. Many software packages are marketed openly as tools for covertly tracking a heating wife
or girlfriendand cost less than £50 Many software packages are marketed openly as tools for covertly tracking a heating wife

and understand the impact of online abuse, including tracking, and action is taken rarely against abusers.
which once installed on a computer or smartphone is virtually untraceable to the user. Nearly all offer a GPS tracking function,
allowing the user to pinpoint an individual to within a few metres, as well as covert access to keystrokes, texts, pictures and emails.
The Independent has been told of a case where a woman had a conversation she had held with a friend on her mobile played back to her by her partner,
who had bugged her phone with spyware. He then told her he had connections with criminals
and had had killed people. In another incident an abusive husband managed to gain access to his spouse ebay account using spyware
and found a delivery address. He then lay in wait and attacked his wife in an assault so vicious that she lost sight in one eye.
The software is being used routinely to exert psychological pressure or for harassment, allowing controlling or potentially violent men to confront their victims over their movements.
In failed relationships, tales are rife of email accounts being hacked to send abusive messages to a spouse friends or employer.
The tracking packages are widely available on the internet with many marketed as ways for employers to monitor the movements of their workers
or for parents to check electronically on the whereabouts of their children. But others openly boast that they can detect infidelity.
lexispy lets you conduct pycalls remotely activating the phone microphone to listen in on its surroundings. This is particularly useful once you confirm she not actually where she told you she was.
the eavesdropping technology is also available in Britain through specialist retailers and also the website of the high-street electronics retailer Maplin.
The company has been marketing a ell phone spy softwaredevice sold for £99. 99 with the ability o monitor SMS text messages,
emails and calls and also keep track of a mobile phone location The website of the manufacturer, Cell Phone Recon,
states that the user of the targeted mobile device will not see the application running. The product listing featured a question from a customer stating she wanted to use the software to spy on her partner texts.
Maplin reply stated: nstalling on the phone is very fast and simple, you will be able to read all texts sent
and received in full. After it was contacted by The Independent, Maplin changed the description of the device to ell phone backup softwareand amended the answer to the customer question to make it clear that it should only be used with the permission of a phone owner.
In a statement, the company said: his product is a brilliant piece of innovation and,
gives users peace of mind. Maplin does not condone using any of its products surreptitiously or as a means of tracking people without their consent and recommends that the product is used legally. hilst
