An international team has, for the first time, developed a way of combining anonymized data from mobile phones and satellite imagery data to create high resolution maps to measure poverty.
Scientists have developed an artificially intelligent, wearable system that can predict if a conversation is happy, sad, or neutral based on a person’s speech patterns and vitals. Coupled with audio and vital-sign data, deep-learning system could someday serve as a ‘social coach’ for people with anxiety or Asperger’s, they say.
Engineers have fabricated transparent, gel-based robots that move when water is pumped in and out of them. The bots can perform a number of fast, forceful tasks, including kicking a ball underwater, and grabbing and releasing a live fish.
For the first time, artificial intelligence has been used to discover the exact interventions needed to obtain a specific, previously unachievable result in vivo, providing new insight into the biophysics of cancer and raising broad implications for biomedicine.
Surgeons have operated on a patient with retinal vein occlusion using a surgical robot. Operated by an eye surgeon, the robot uses a needle of barely 0.03 millimeter to inject a thrombolytic drug into the retinal vein of the patient.
Autonomous systems — like driverless cars — perform tasks that previously could only be performed by humans. In a new article, artificial intelligence ethics experts argue that current safety regulations do not plan for these systems and are therefore ill-equipped to ensure that autonomous systems will perform safely and reliably.
Underwater robots offer scientists an extraordinary new tool to study ocean currents and the tiny creatures they transport. Swarms of these underwater robots helped answer some basic questions about the most abundant life forms in the ocean — plankton.
Using a novel approach for computing real-time game strategy, engineers have developed an artificial Ms. Pac-Man player that chomps the existing high score for computerized play.
Researchers have developed a way to manufacture microscale-sized machines from biomaterials that can safely be implanted in the body. Working with hydrogels, they have invented a new technique that stacks the soft material in layers to make devices that have three-dimensional, freely moving parts. The study demonstrates a fast manufacturing method they call “implantable microelectromechanical systems.”
Controls engineers have developed practical strategies for building and coordinating scores of sensor-laden balloons within hurricanes. Using onboard GPS and cellphone-grade sensors, each drifting balloon becomes part of a ‘swarm’ of robotic vehicles, which can periodically report, via satellite uplink, their position, the local temperature, pressure, humidity and wind velocity.
