Algorithm Lets Robots Assemble Things on the Fly

May 28, 2015 7:00 am | by MIT, Larry Hardesty | Videos | Comments

A new algorithm can significantly reduce robot teams’ planning time. The plan the algorithm produces may not be perfectly efficient, but in many cases, the savings in planning time will more than offset the added execution time. Researchers tested the viability of the algorithm by using it to guide a crew of three robots in the assembly of a chair.

Genetic Testing is Flawed

May 28, 2015 7:00 am | by Associated Press, Marilynn Marchione | News | Comments

The first report from a public-private project to improve genetic testing shows it is not as rock solid as many people believe, with flaws that result in some people wrongly advised to worry about a disease risk and others wrongly told to relax. Researchers say the study shows the need for consumers to be careful about choosing where to have a gene test done and acting on the results, such as having or forgoing a preventive surgery.

e-Stent Provides Feedback, Therapy Before Dissolving

May 28, 2015 7:00 am | by ACS | News | Comments

Every year, an estimated half-million Americans undergo surgery to have a stent prop open a coronary artery narrowed by plaque. But sometimes the mesh tubes get clogged. A multi-tasking stent could minimize the risks associated with the procedure. It can sense blood flow and temperature, store and transmit the information for analysis and can be absorbed by the body after it finishes its job.

Perfume Researchers Seek Less Odorous Latrines

May 27, 2015 3:00 pm | by ACS | News | Comments

About 2.5 billion people worldwide don't have access to sanitary toilets. Latrines are an option for many of those people, but these facilities' overwhelming odors can deter users, who then defecate outdoors instead. To improve this situation, fragrance scientists paired experts' noses and analytical instruments to determine the odor profiles of latrines with the aim of countering the offensive stench.
