An application can make your phone spy on you

1
LONDON: US military experts have demonstrated a new smartphone app that can turn your mobile's camera into a spying tool forcyber criminals, secretly beaming images of your house, chequebook and other private information back to them.
The software can even build up a 3D model of your house, from which the hackers can inspect your rooms, potentially gleaning information about valuables in your home, calendar entries as well as spying on you.
The app 'PlaiceRaider' was created by US military experts at Naval Surface Warfare Center in Crane, Indiana, to show how cybercriminals could operate in the future, the Daily Mail reported. The creators even demonstrated how they could read the numbers of a cheque book when they tested the Android software on 20 volunteers. As long as the app could be installed on the users phone, it can instantly begin beaming back images from the phone when it senses the right conditions, and software on the other end can then re-construct maps of the visited room.
The team gave their infected phone to 20 individuals, who did not know about the malicious app, and asked them to continue operating in their normal office environment. The team said they could glean vital information from all 20 users, and that the 3D reconstruction made it much easier to steal information than by just using the images alone.
Researcher Robert Templeman said their app can run in the background of any smartphone using the Android 2.3 operating system. Through use of phone's camera and other sensors, PlaceRaider constructs 3-D models of indoor environments. "Remote burglars can thus download the physical space, study the environment carefully, and steal virtual objects from the environment," researchers said.

Scientists develop world's first 'biological Internet'

Bio-engineers are harnessing the key attibutes of a virus, M13, such as its ability to package and broadcast arbitrary DNA strands, to create the first biological internet or 'Bi-Fi.'Bio-engneering researchers Monica Ortiz and Drew Endy from Stanford University have created a biological mechanism to send genetic messages from cell to cell.
The system boosts the complexity and amount of data that can be communicated between cells and could lead to greater control of biological functions within cell communities, the Journal of Biological Engineering reports.
Biological internet could lead to biosynthetic factories in which huge masses of microbes collaborate to make more complicated fuels, pharmaceuticals and other useful chemicals, including the regeneration of tissue or organs in future, according to a Stanford statement.
Ortiz was even able to broadcast her genetic messages between cells separated by a gelatinous medium at a distance greater than seven centimetres.
"That's very long-range communication, cellularly speaking," she said.
M13 is a packager of genetic messages. It reproduces within its host, taking strands of DNA strands that engineers can control wrapping them up one by one and sending them out encapsulated within proteins produced by M13 that can infect other cells.
Once inside the new hosts, they release the packaged DNA message. The M13-based system is essentially a communication channel. It acts like a wireless Internet connection that enables cells to send or receive messages, but it does not care what secrets the transmitted messages contain.
"Effectively, we've separated the message from the channel. We can now send any DNA message we want to specific cells within a complex microbial community," said Ortiz, who led the study.
It is well-known that cells naturally use various mechanisms, including chemicals, to communicate, but such messaging can be extremely limited in both complexity and bandwidth.
Simple chemical signals are typically both message and messenger two functions that cannot be separated.
"If your network connection is based on sugar then your messages are limited to 'more sugar,' 'less sugar,' or 'no sugar'" explained Endy.
Cells engineered with M13 can be programmed to communicate in much more complex, powerful ways than ever before. In harnessing DNA for cell-cell messaging the researchers have also greatly increased the amount of data they can transmit at any one time. In digital terms, they have increased the bit rate of their system.

Now, there`s long-term control of allergic asthma
Washington: When children suffer from allergies and asthma induced by dust mites, finding relief seems an uphill task. Researchers now claim that three years of allergy shots would offer long-term control of allergic asthma.

Allergic children react to proteins within the bodies and faeces of the mites. These particles are found mostly in pillows, mattresses, carpeting, stuffed animals and upholstered furniture. Researchers say there may be as many as 19,000 dust mites in one gram of dust!

"The recommended duration of immunotherapy for long-term effectiveness has been three to five years," said Iwona Stelmach, from the American College of Allergy, Asthma and Immunology (ACAAI), who led the study.

"Our research shows that three years is an adequate duration for the treatment of childhood asthma associated with house dust mites. An additional two years adds no clinical benefit," adds Stelmach, quoted in the journal Annals of Allergy, Asthma and Immunology.

Immunotherapy, also known as allergy shots, can alter the progression of allergic disease. The treatment eases patients of symptoms, while preventing asthma and the development of other allergies, according to an ACAAI statement.

The study found that 50 percent of children with asthma due to dust mites experienced remission after three years of treatment, with greatly reduced or no controller medications needed at that point.

It has long been observed that the effectiveness of allergy shots continues long after treatment has been completed," said allergist James Sublett, who holds the chair of the ACAAI Indoor Environment Committee.

"This study is among the first to look at the benefits of different lengths of therapy. Not only does it provide long-term therapeutic benefits for both children and adults, it can reduce total healthcare costs by 33 to 41 percent."
