The ultimate test of wits in computer security occurs through open competition on the global Capture the Flag (CTF) tournament circuit. In CTF contests, experts reverse engineer software, probe its weaknesses, search for deeply hidden flaws, and create securely patched replacements.

On August 4, 2016, DARPA will hold the Cyber Grand Challenge, the world’s first all-computer CTF tournament. It will take place live on stage co-located with the DEF CON conference in Las Vegas. The public is invited to attend and observe as automated systems take the first steps towards a defensible, connected future.

MIT engineers have developed a microfluidic device that replicates the neuromuscular junction—the vital connection where nerve meets muscle. The device, about the size of a U.S. quarter, contains a single muscle strip and a small set of motor neurons. Researchers can influence and observe the interactions between the two, within a realistic, three-dimensional matrix.

The researchers genetically modified the neurons in the device to respond to light. By shining light directly on the neurons, they can precisely stimulate these cells, which in turn send signals to excite the muscle fiber. The researchers also measured the force the muscle exerts within the device as it twitches or contracts in response.

The team’s results, published online today in Science Advances, may help scientists understand and identify drugs to treat amyotrophic lateral sclerosis (ALS), more commonly known as Lou Gehrig’s disease, as well as other neuromuscular-related conditions.

Quantum computers promise speedy solutions to some difficult problems, but building large-scale, general-purpose quantum devices is a problem fraught with technical challenges.

To date, many research groups have created small but functional computers. By combining a handful of atoms, electrons or superconducting junctions, researchers now regularly demonstrate quantum effects and run simple —small programs dedicated to solving particular problems.

But these laboratory devices are often hard-wired to run one program or limited to fixed patterns of interactions between the quantum constituents. Making a quantum computer that can run arbitrary algorithms requires the right kind of physical system and a suite of programming tools. Atomic , confined by fields from nearby electrodes, are among the most promising platforms for meeting these needs.

Interesting and true on many situations; and will only expand as we progress in areas of AI, QC, and Singularity as well.

The use of algorithms to filter and present information online is increasingly shaping our everyday experience of the real world, a study published by Information, Communication & Society argues.

Associate Professor Michele Willson of Curtin University, Perth, Australia looked at particular examples of computer algorithms and the questions they raise about personal agency, changing world views and our complex relationship with technologies.

Algorithms are central to how information and communication are located, retrieved and presented online, for example in Twitter follow recommendations, Facebook newsfeeds and suggested Google map directions. However, they are not objective instructions but assume certain parameters and values, and are in constant flux, with changes made by both humans and machines.

I see many uses for this such as provider services including front office & hospital admissions, security in assessing people in line or trying to gain entry, etc.

Machines are taking over more and more tasks. Ideally, they should also be capable to support the human in case of poor performance. To intervene appropriately, the machine should understand what is going on with the human. Fraunhofer scientists have developed a diagnostic tool that recognizes user states in real time and communicates them to the machine.

The camera firmly focuses on the driver’s eyes. If they are closed for more than one second, an alarm is triggered. This technique prevents the dangerous micro-sleep at the wheel. “It is not always as easy for a machine to detect what state the human is in, as it is in this case,” says Jessica Schwarz from the Fraunhofer Institute for Communication, Information Processing and Ergonomics FKIE in Wachtberg, just south of Bonn.

Holistic model feeds real-time diagnosis

For her doctoral thesis, the graduate psychologist examined the question of how to very precisely determine user states, what influence these may have on incorrect behavior and how automated systems can use this information. “For complex applications it is not sufficient to focus on only one impact factor,” says the scientist. An increased heart rate, for example, does not automatically mean that a person is stressed. This can have various causes. Schwarz therefore examined what factors specifically impact human performance and created a holistic model that provides a detailed view on user states and their causes.
