Brain works like a radio receiver
Initial evidence is found that the brain has a ‘tuning knob’ that is actually influencing behavior. Brain circuits can tune into the frequency of other brain parts relevant at the time. The scientific magazine Neuron is publishing the results of researchers at Radboud University the Netherlands on January 22.
Animals (and humans alike) have a metal map of the surrounding environment, consisting of place cells. These cells correspond with places in the physical space and fire when the animal reaches the place or remembers it. The mental map is fed by two sorts of information: with memories from earlier experiences, and with sensory information. But how does the mental map upload this information?
Direct measurements in the brain of mice, looking for their way in a maze, show that memory information is sent with another frequency to the mental map than sensory information is. The brain area representing the mental map synchronizes with these frequencies like a radio receiver: it is only tuning into the information that is important at a given time, an international team of researchers led by Francesco Battaglia from the Donders Institute for Brain, Cognition and Behaviour at Radboud University Nijmegen show. This research sheds light on the intriguing question how brain parts choose relevant information from the constant scattering of neurons going on in the brain.

HP’s New Jet Fusion 3D Printers Can Print Electronics Inside a Product
HP has announced that they will be releasing their first generation 3D printers by the end of the year. The Multi Jet Fusion Technology allows 3D printing at half the cost and ten times the speed.
HP has released two new 3D printer models, the Jet Fusion 3200 and Jet Fusion 4200—their first products on the market since the company entered the 3D printing arena in 2014. These high-end printers do not need lasers (like most rivals in their range) and will be available by the end of the year.
Not only will the printers be able to print at half the cost and ten times the speed of other printers on the market, but to top it all off, they can produce sharp, fine, high-definition edges.
Ransomware: the digital plague infecting the world
“The individuals who do these types of attacks are well aware of the pressure points and pain points, economic-wise,” says Dr. John Hale, a cybersecurity expert at the University of Tulsa. “They know what they can extract, how much they can extract.
“They prey upon two things: an organization’s reliance on information systems and two, the common situation, where an organization is a little bit behind on backup procedures and policies to prevent these types of things. It really is easy pickings for the bad guys.”
Crypto ransomware is designed to encrypt data stored on the computer, making the data useless unless the user obtains the key to decrypt it. A message details the ransom, which is typically paid in digital currencies such as bitcoin. Locker ransomware locks the computer or device’s interface — save for the ability to interact with the hacker — and demands money to restore it.
Technique to Teach Robots New Tricks Developed: Study
As robots become more pervasive in society, humans will want them to do chores like cleaning the house or cooking, researchers said.
However, to get a robot started on a task, people who are not computer programmers will have to give it instructions, they said.
“We want everyone to be able to programme, but that is probably not going to happen,” said Matthew Taylor from Washington State University (WSU).
