Scientists Design Bacteria to Reflect 'Sonar' Signals for Ultrasound Imaging

In the 1966 science fiction film Fantastic Voyage, a submarine is shrunken down and injected into a scientist's body to repair a blood clot in his brain. While the movie may be still be fiction, researchers at Caltech are making strides in this direction: they have, for the first time, created bacterial cells with the ability to reflect sound waves, reminiscent of how submarines reflect sonar to reveal their locations.

Ophthalmologists Increasingly Dissatisfied with Electronic Health Records

Ophthalmologists' use of electronic health records (EHR) systems for storing and accessing patients' medical histories more than doubled between 2006 and 2016, while their perceptions of financial and clinical productivity following EHR implementation declined, a study published in JAMA Ophthalmology shows.

The Importance of the Robot iCub as a Standard Robotic Research Platform for Embodied AI

Robotic research benefited in the last ten years of a standardized common open-source platform for research on embodied artificial intelligence (AI): the humanoid robot iCub. Born in Italy, today it is available in 36 copies in laboratories across Europe, USA, South Korea, Singapore and Japan and more than hundred researchers worldwide contribute to develop its skills.

Robotic Device Improves Balance and Gait in Parkinson's Disease Patients

Some 50,000 people in the U.S. are diagnosed with Parkinson's disease (PD) every year. The American Institute of Neurology estimates there are one million people affected with this neurodegenerative disorder, with 60 years as average age of onset. Falls and fall-related injuries are a major issue for people with Parkinson's - up to 70 percent of advanced PD patients fall at least once a year and two-thirds suffer recurring falls.

Twitter can Reveal our Shared Mood

In the largest study of its kind, researchers from the University of Bristol have analysed mood indicators in text from 800 million anonymous messages posted on Twitter. These tweets were found to reflect strong patterns of positive and negative moods over the 24-hour day.

Circadian rhythms, widely referred to as the 'body clock', allows people's bodies to predict their needs over the dark and light periods of the day.

Video Game Improves Doctors' Recognition and Triage of Severe Trauma Patients

Playing an adventure video game featuring a fictitious, young emergency physician treating severe trauma patients was better than text-based learning at priming real doctors to quickly recognize the patients who needed higher levels of care, according to a new trial led by the University of Pittsburgh School of Medicine. The results, published by The BMJ, held even though doctors assigned to the game enjoyed it less than those assigned to traditional, text-based education.

Researchers 3-D Print Lifelike Artificial Organ Models

A team of researchers led by the University of Minnesota has 3D printed lifelike artificial organ models that mimic the exact anatomical structure, mechanical properties, and look and feel of real organs. These patient-specific organ models, which include integrated soft sensors, can be used for practice surgeries to improve surgical outcomes in thousands of patients worldwide.
