Scientists have developed a new material that can undulate and therefore propel itself forward under the influence of light. To this end, they clamp a strip of this polymer material in a rectangular frame. When illuminated it goes for a walk all on its own. This small device, the size of a paperclip, is the world's first machine to convert light directly into walking, simply using one fixed light source. The researchers publish their findings in Nature.
Researchers combined gecko-inspired adhesives and a custom robotic gripper to create a device for grabbing space debris. They tested their gripper in multiple zero gravity settings, including the International Space Station.
Patients with common widespread forms of cancer will enjoy longer life expectancy and reduced risk of recurrence thanks to a multimodal optical spectroscopy probe developed by Canadian researchers.
Ask Siri to find a math tutor to help you 'grasp' calculus and she's likely to respond that your request is beyond her abilities. That's because metaphors like 'grasp' are difficult for Apple's voice-controlled personal assistant to, well, grasp. But new UC Berkeley research suggests digital helpers could someday learn the algorithms that humans have used for centuries to create and understand metaphorical language.
ASU professor and colleagues suggest a new approach to scientific exploration that they call exploration telepresence.
A new review paper proposes that the goal of memory is not to transmit the most accurate information over time, but to guide and optimize intelligent decision making by only holding on to valuable information.
Researchers at MIT and Massachusetts General Hospital have developed a new system that can efficiently search through hundreds of hours of video for events and visual features that correspond to a few training examples. In work they presented at the International Conference on Robotics and Automation this month, the researchers trained their system to recognize different stages of an operation, such as biopsy, tissue removal, stapling, and wound cleansing.
Researchers at Numenta have introduced two contributions to the field of anomaly detection for streaming applications. The first is a novel unsupervised anomaly detection technique based on a theory of how the brain works. The second is a benchmark that provides a controlled open-source environment for testing anomaly detection algorithms on streaming data. These contributions appear in a new peer-reviewed paper, Unsupervised real-time anomaly detection for streaming data, published in a special issue of Neurocomputing.
Researchers at UC Santa Barbara professor Yasamin Mostofi's lab have given the first demonstration of 3-D imaging of objects through walls using ordinary wireless signal. The technique, which involves two drones working in tandem, could have a variety of applications, such as emergency search-and-rescue, archaeological discovery and structural monitoring.
Researchers from the University of Luxembourg, in cooperation with the University of Strasbourg, have developed a computational method that could be used to guide surgeons during brain surgery.
