WiFi signals can be exploited to detect attackers
Physical attacks on devices connected to the Internet can be detected by analysing WiFi signals, computer scientists have discovered. Wireless devices are increasingly used for critical roles, such as security systems or industrial plant automation. Although wireless transmissions can be encrypted to protect transmitted data, it is hard to determine if a device - such as a wirelessly connected security camera protecting critical buildings in airports or power stations - has been tampered with.

How to feed and raise a Wikipedia robo-editor
Dr Mehrnoosh Sadrzadeh from QMUL's School of Electronic Engineering and Computer Science looks at what it takes to teach an AI how to read natural human languages. Wikipedia is to put artificial intelligence to the enormous task of keeping the free, editable online encyclopedia up-to-date, spam-free and legal.

Lie-detecting software uses real court case data
ANN ARBOR-By studying videos from high-stakes court cases, University of Michigan researchers are building unique lie-detecting software based on real-world data. Their prototype considers both the speaker's words and gestures, and unlike a polygraph, it doesn't need to touch the subject in order to work.

New research offers quantum leap for long-distance secure communications
A new tele technique which harnesses quantum technology could lead to a much more secure form of worldwide internet , scientists have reported. In a new paper published today (Tuesday 24 November) in the journal Nature , researchers from the Universities of Glasgow, Stanford, Tokyo and Würzburg describe how they have implemented a novel tool for a long-distance telecommunication link which is impossible for hackers to breach.

Revealing the mysteries of the Maya script
Revealing the mysteries of the Maya script
02. EPFL researchers have come up with an algorithm to analyze Mayan writing. This project could one day contribute to translating this complex and still partially unknown language. While some five million people still speak a language that evolved out of Mayan civilization in South America, the written language has suffered a different fate.

How we use our smartphones twice as much as we think
People use their smartphones for an average of five hours a day - about a third of the time they are awake - and check them about 85 times a day, research suggests. The study in the journal PLOS ONE compared the amount of time participants estimated they spent on their smartphones with their actual usage.

One click away from the perfect outfit
One click away from the perfect outfit
Whether shopping online or offline, everyone knows how difficult it can be to find the right outfit. Fashwell, an ETH spin-off, now has a remedy for that. Its app unites social media and online shopping to help users track down the clothes they like. Anyone who thinks fashion and computer science are two irreconcilable concepts and that fashion is inherently out of place in a technical course would quickly change their opinion with a single visit to the ETH spin-off Fashwell.

Upgrading the quantum computer 25.09.2015 Simulation of Chiral Edge States in a Quantum System
Upgrading the quantum computer 25.09.2015 Simulation of Chiral Edge States in a Quantum System
Theoretical physicists in Innsbruck have proposed a scalable quantum computer architecture. The new model, developed by Wolfgang Lechner, Philipp Hauke and Peter Zoller, overcomes fundamental limitations of programmability in current approaches that aim at solving real-world general optimization problems by exploiting quantum mechanics.

Affordable camera reveals hidden details invisible to the naked eye
Affordable camera reveals hidden details invisible to the naked eye
Peering into a grocery store bin, it's hard to tell if a peach or tomato or avocado is starting to go bad underneath its skin. But an affordable camera technology being developed by the University of Washington and Microsoft Research might enable consumers of the future to tell which piece of fruit is perfectly ripe or what food in the fridge is going rotten.

A major proof of concept for brain simulation
A major proof of concept for brain simulation
08. An international team led by EPFL scientists have completed a first draft computer reconstruction of a piece of the neocortex. The electrical behavior of the virtual brain tissue was simulated on supercomputers and found to match the behavior observed in a number of experiments on the brain. Further simulations revealed novel insights into the functioning of the neocortex.

Computing A Textbook of Crystal Physics
Computing A Textbook of Crystal Physics
Disturbing a material's crystal lattice can create a charge imbalance that leads to a voltage across the material. This phenomena, called the "piezoelectric effect," was first demonstrated in 1880 by Jacques and Pierre Curie in materials such as quartz, topaz and Rochelle salt. Today, piezoelectricity is recognized as a valuable property and the market for piezoelectric materials is rapidly expanding with applications that encompass a variety of technologies, ranging from medical imaging to sonar to energy harvesting.

Babies Time Their Smiles to Make Their Moms Smile in Return
Why do babies smile when they interact with their parents? Could their smiles have a purpose? In the Sept. 23 issue of PLOS ONE , a team of computer scientists, roboticists and developmental psychologists confirm what most parents already suspect: when babies smile, they do so with a purpose-to make the person they interact with smile in return.

Rail bound traffic vulnerable to terrorist attacks
The implications of terrorist attacks targeting trains are becoming increasingly extensive. The number of casualties has increased and there has been a fivefold in injuries since the 1970-80s. At the same time, more than half of the attacks are carried out without any injuries or casualties according to a dissertation from Umeå University in Sweden.

Robot scientist on show
Children will be given the chance to meet the original robot scientist in a series of demonstrations at London's Science Museum this week. Professor Ross D. King, from the University of Manchester's School of Computer Science, will join academic colleagues to demonstrate just what ADAM, a machine who thinks and does experiments like a human scientist, is capable of.
