Tiny Robots Crawl Through Mouse's Stomach To Release Antibiotics

Wed, 08/16/2017 - 10:02am
Tiny robotic drug deliveries could soon be treating diseases inside your body. For the first time, micromotors -- autonomous vehicles the width of a human hair -- have cured bacterial infections in the stomachs of mice, using bubbles to power the transport of antibiotics. From a report: "The movement itself improves the retention of antibiotics on the stomach lining where the bacteria are concentrated," says Joseph Wang at the University of California San Diego, who led the research with Liangfang Zhang. In mice with bacterial stomach infections, the team used the micromotors to administer a dose of antibiotics daily for five days. At the end of the treatment, they found their approach was more effective than regular doses of medicine. The tiny vehicles consist of a spherical magnesium core coated with several different layers that offer protection, treatment, and the ability to stick to stomach walls. After they are swallowed, the magnesium cores react with gastric acid to produce a stream of hydrogen bubbles that propel the motors around. This process briefly reduces acidity in the stomach. The antibiotic layer of the micromotor is sensitive to the surrounding acidity, and when this is lowered, the antibiotics are released.

Amazon Will Pay Developers With the Most Engaging Alexa Skills

Wed, 08/16/2017 - 8:41am
Amazon today announced a new program to bring revenue to developers of Alexa skills based on how much engagement their voice app is able to generate among users of Alexa-enabled devices. From a report: Amazon appears to be the first of the major tech companies with AI assistants and third-party integrations -- like Google, Samsung, Apple, and Microsoft -- with a program to compensate developers based on engagement created by their voice app. Metrics used to measure engagement of an Alexa skill include minutes of usage, new customers, customer ratings, and return visitors, an Amazon spokesperson told VentureBeat. Developers of Alexa skills in the U.S., U.K., and Germany are eligible to join. Developers with a skill active in all three countries will receive separate payments based on engagement in each country.

Higher Minimum Wages Bring Automation and Job Losses, Study Suggests

Wed, 08/16/2017 - 8:01am
An anonymous reader shares a report via email: As of the start of the year, 19 U.S. states had raised minimum wages, dramatizing a long simmering debate: Do minimum wages kill jobs, and make the working class worse off in the end? Or do they simply make them a little richer, with little or no loss to overall employment? In a new paper, economists Grace Lordan of the London School of Economics and David Neumark of UC Irvine parse 35 years of census data and come down on the worse-off side: For lower-skill jobs like bookkeepers and assembly-line workers, they say, higher minimum wages encourage employers to automate -- according to their calculations, a $1 increase can cost tens of thousands of jobs nationally.
