Statistical model helps police identify crime series; speeds apprehension of perpetrators Aug 11th 2015, 14:35 A statistical model -- now an easy-to-use software tool -- local police can use to identify a series of related crimes and nab a suspect has been unveiled. Crime linkage is the investigative process of identifying a crime series--a group of crimes committed by the same person or group of people. The goal of the crime linkage model and resulting software is to help crime analysts more quickly and easily sift through massive amounts of crime data to accurately discover patterns that could indicate a crime series such as one of the most difficult crimes to solve: burglaries.

Fortifying computer chips for space travel Sep 4th 2015, 23:53 Space is cold, dark, and lonely. Deadly, too, if any one of a million things goes wrong on your spaceship. It's certainly no place for a computer chip to fail, which can happen due to the abundance of radiation bombarding a craft. Worse, ever-shrinking components on microprocessors make computers more prone to damage from high-energy radiation like protons from the sun or cosmic rays from beyond our galaxy. 'Spin current' seen in motion for the first time Sep 4th 2015, 02:43 Researchers have for the first time seen a spin current -- an inherent magnetic property common to all electrons -- as it travels across materials.

Photonic chip activated for communication with light Sep 14th 2015, 13:31 Sending information with the help of light is an exciting prospect for future technologies. It requires 'light chips', made of a special glass. Scientists have now managed to equip these light chips - which were already known for their extremely low losses - with new 'active' functionalities, such as generating, strengthening, and modulating light. Their chip is capable of creating a very wide light spectrum that runs from blue to infrared, spanning wavelengths of 470 to 2130 nanometers. By doing so they have made a light chip with the largest frequency range ever.

Sep 9th 2015, 16:48

When tweeters use hashtags, they tend to be more formal and drop the use of abbreviations and emoticons. But when they use the @ symbol to address smaller audiences, they're more likely to use non-standard words such as 'nah,' 'cuz' and 'smh.' When they tweet to others in the same city, they're more likely to use unique words specific to that area, a new study shows.
