Researchers use light to turn yeast into biochemical factories

( Princeton University, Engineering School) Researchers have used a combination of light and genetic engineering to controlling the metabolism, or basic chemical process, of a living cell. Building on techniques that already have transformed the field of neuroscience, the researchers used light to control genetically-modified yeast and increase its output of commercially valuable chemicals.

For graphite pellets, just add elbow grease

( Rice University) Rice University researchers crush and press functionalized graphene to make strong, light graphite pellets that hold promise for electronic and catalytic applications.

NASA eyes powerful Tropical Cyclone Marcus

( NASA/Goddard Space Flight Center) While a Category 4 hurricane on the Saffir-Simpson hurricane wind scale, NASA-NOAA's Suomi NPP satellite passed over Tropical Cyclone Marcus in the Southern Indian Ocean.

Measurement chip detects Legionella

( Technical University of Munich (TUM)) In an outbreak of Legionnaires' disease, finding the exact source as quickly as possible is essential to preventing further infections. To date, a standard analysis takes days. Researchers at the Technical University of Munich have now developed a rapid test that achieves the same result in about 35 minutes.

AI tool promotes positive peer groups to tackle substance abuse

( University of Southern California) When it comes to fighting substance abuse, research suggests the company you keep can make the difference between recovery and relapse. Researchers from the USC Center for Artificial Intelligence in Society have created an algorithm that sorts intervention program participants -- who are voluntarily working on recovery -- into smaller groups, or subgroups, in a way that maintains helpful social connections and breaks social connections that could be detrimental to recovery.

Battle rhythm: Navy looking at sleep, decision-making links

( Office of Naval Research) In the military, operational tempo is fast paced and the mission takes top priority -- day or night. Such dedication, however, can cause sleep to become a lower priority and fatigue a dangerous reality.

The efficiency of nature-inspired metaheuristics in limited-budget expensive global optimization

( Lobachevsky University) Global optimization problems where evaluation of the objective function is an expensive operation arise frequently in engineering, machine learning, decision making, statistics, optimal control, etc.

A wearable system to monitor the stomach's activity throughout the day

( University of California - San Diego) A team of researchers has developed a wearable, non-invasive system to monitor electrical activity in the stomach over 24 hours--essentially an electrocardiogram but for the gastro-intestinal (GI) tract.Applications include monitoring GI activity for patients outside of a clinical setting, which cuts down costs. Monitoring for longer periods of time also increases the likelihood of capturing abnormal events.Researchers detail their findings in the March 22 issue of Nature's open access journal Scientific Reports.

NASA sees Tropical Cyclone 16P develop

( NASA/Goddard Space Flight Center) NASA's Terra satellite passed over the Arafura Sea and captured an image of newly developed Tropical Cyclone 16P.

Southwestern Pennsylvania manufacturers get student support

( University of Pittsburgh) Catalyst Connection is one of only 60 manufacturing extension partnership centers throughout the 50 states. They provide improvement services and consultation to companies in the 14 counties of southwestern Pennsylvania. After recognizing the many similarities between Catalyst Connection's work and the work Pitt students were doing in the classroom, the two joined forces.
