Rückverfolgbarkeit von Fischprodukten nicht ausreichend

Fischprodukte von Iglo kann der Verbraucher am schlechtesten zurückverfolgen, die von Frosta am besten. Das ist das Ergebnis eines Greenpeace-Tests von Juni. Zehn verschiedene Fischmarken im Vergleich zeigen: Die Rückverfolgbarkeit von Speisefischen reicht noch lange nicht.

Bei dem Test untersuchte Greenpeace die Informationen, die der Käufer über den Tracking- beziehungsweise QR-Code bekommt. Iglo schnitt dabei am schlechtesten ab: Zu nur 24 Prozent erfüllte das Unternehmen die von Greenpeace geforderten Angaben über Herkunft und Verarbeitung. Bei Frosta sieht das mit 65 Prozent schon anders aus. “Iglo gibt über seinen Trackingcode nicht mehr Informationen preis, als bereits auf der Verpackung angegeben sind. Das ist aus unserer Sicht eine Verbrauchertäuschung”, sagt Iris Menn, Meeresexpertin bei Greenpeace. (more…)

MU Researchers Develop App that Could Save Cattle Lives, Farmers’ Wallets

App also allows users to communicate with MU animal science experts

COLUMBIA, Mo. – Each year, overheated cattle cost farmers more than $1.2 billion. Now, researchers at the University of Missouri have created a smartphone application that can detect when a cow is at risk for heat stress. The app also can offer the best methods for intervention.

“Cows are like the rest of us,” said Don Spiers, professor of animal sciences at MU’s College of Agriculture, Food and Natural Resources, who led the team that developed the app. “They slow down in hot and humid weather. When stressed by too much heat, they stop eating, and thus, fail to grain weight or produce milk.” (more…)

Microbial Who-Done-It for Biofuels

New Technique Identifies Populations Within a Microbial Community Responsible for Biomass Deconstruction

One of the keys to commercialization of advanced biofuels is the development of cost-competitive ways to extract fermentable sugars from lignocellulosic biomass. The use of enzymes from thermophiles – microbes that thrive at extremely high temperatures and alkaline conditions – holds promise for achieving this. Finding the most effective of these microbial enzymes, however, has been a challenge. That challenge has now been met by a collaboration led by researchers with the U.S. Department of Energy (DOE)’s Joint BioEnergy Institute (JBEI). (more…)

Stunning images of Andromeda demonstrate the world’s most powerful astronomical camera

Stunning images of the Andromeda Galaxy are among the first to emerge from a new wide-field camera installed on the enormous Subaru Telescope atop the Hawaiian mountain Mauna Kea. The camera, called the Hyper-Suprime Cam (HSC), is the result of an international collaboration between Princeton University astrophysicists and Japanese and Taiwanese scientists.

With this new camera, researchers will be able to conduct a “cosmic census” of hundreds of millions of galaxies in a wide swath of sky in sufficient depth to probe mysteries such as dark matter and dark energy, while searching for baby galaxies in the early universe. The images of the Andromeda Galaxy demonstrate the new camera’s ability to capture images for a large-scale survey that will help scientists understand the evolutionary history and fate of the expanding universe. The camera’s enormous field of view allowed the entire Andromeda Galaxy, which is some 60,000 light years across, to be captured in a single shot. (more…)

Changes in language and word use reflect our shifting values, UCLA psychologist reports

Study analyzes more than 1 million books published over 200 years

A new UCLA analysis of words used in more than 1.5 million American and British books published between 1800 and 2000 shows how our cultural values have changed.

The increase or decrease in the use of certain words over the past two centuries — a period marked by growing urbanization, greater reliance on technology and the widespread availability of formal education — reveals how human psychology has evolved in response to major historical shifts, said Patricia Greenfield, a distinguished professor of psychology at UCLA and the author of the study.
