Scientists have long speculated about the source of significant quantities of hydrogen that have been observed at the moon's lunar poles, and just a few months ago NASA announced that water molecules were indeed present, but in relatively small amounts. Now the Lunar CRater Observing and Sensing Satellite (LCROSS) that was employed to shed some more light on the presence of water on the moon, looks like it has done just that with preliminary data indicating the mission successfully uncovered water in a permanently-shadowed crater.

Software to detect objects inside videos

Researchers at the University of Missouri (MU) are developing software that would enable computers to perform video analysis tasks, such as alerting emergency services if a video surveillance camera detects a person falling and not getting up. The software could also be used to search inside videos and look for certain objects, such as basketballs or footballs, hence reducing the time taken to locate a certain game or scene. Read More
Gel sensors to detect bomb chemicals and illegal drugs in seconds

Sensors that quickly detect chemicals used to make bombs are being developed by scientists at Queen’s University, Belfast. The devices will use special gel pads to "swipe" a person or crime scene to gather a sample which is then analyzed by a scanning instrument that can detect the presence of chemicals within seconds, much quicker than current analysis methods. This will allow better, faster decisions to be made in response to terrorist threats. The team is also working on devices that detect illegal drugs and will hopefully be deployed by police as roadside drug "breathalyzers". Read More
