Smartphone users value their privacy and are willing to pay for it, CU-Boulder economists find

Average smartphone users are willing to pay up to $5 extra for a typical application—or “app”—that won’t monitor their locations, contact lists and other personal information, a study conducted by two economists at the University of Colorado Boulder has found. (more…)

Database Tracks Toxic Side Effects of Pharmaceuticals

Sometimes the cure can be worse than the disease. Pharmaceutical drugs are known for their potential side effects, and an important aspect of personalized medicine is to tailor therapies to individuals to reduce the chances of adverse events. Now researchers from North Carolina State University have updated an extensive toxicology database so that it can be used to track information about therapeutic drugs and their unintentional toxic effects.

“Environmental science actually shares a common goal with drug makers: to improve the prediction of chemical toxicity,” says Dr. Allan Peter Davis, lead author of a paper on the work and the biocuration project manager of the Comparative Toxicogenomics Database (CTD) in NC State’s Department of Biological Sciences.

Ökozid zum Verbrechen erklären

EU-Bürgerinitiative „EndEcocide“ sammelt Unterschriften für Mutter Erde

Die Erde ist unsere Heimat. Sie fällt dem Wunsch nach Wohlstand zum Opfer, sie leidet unter dem rücksichtslosen Wirtschaftssystem. Firmen wie Gazprom und Shell haben offiziell das Recht, ganze Ökosysteme zu gefährden. Unser Planet kann sich erneuern – aber seine Kapazitäten sind erschöpft. Jetzt kann sich jeder ganz einfach dafür einsetzen, dass Umweltsünder offiziell bestraft werden.

Vor einem Jahr entschied die britische Anwältin Polly Higgins, sich eine Auszeit zu nehmen. Sie fand, es sei nun die Natur, die eine Vertreterin ihrer Rechte benötige. Higgins gelangte zur Überzeugung, dass dem naturzerstörenden Wirtschaftssystem mit einer bestimmten Maßnahme begegnet werden kann: Ökozid muss als Verbrechen gelten. (more…)

Zebrafish help decode link between calcium deficiency and colon cancer

ANN ARBOR — A tiny, transparent fish embryo and a string of surprises led scientists to a deeper understanding of the perplexing link between low calcium and colon cancer.

By studying zebrafish embryo skin, University of Michigan researchers decoded cell messages underlying abnormal colonic cell growth of the kind that can lead to tumors and colon cancer in calcium deficient individuals. They have also tested this new mechanism in human colon cancer cells. (more…)

Pilot program study finds that pediatric obesity patients like telehealth services

For youth dealing with obesity who need extra help losing weight, experts suggest a multidisciplinary approach in which care is provided by several health specialists. However, the logistics of traveling to multiple appointments, even if just across town, can be a barrier to receiving care, especially for low-income families.

UCLA researchers who work with this patient population set up a pilot program using telehealth technology — a secure system that allowed patients to see and speak with their health care providers at UCLA over a computer from their local health clinic — to evaluate if such a system could be an effective strategy to help overcome these issues.

Drei tote Wölfe in einer Woche

NABU fordert Kompetenzstelle für den Wolfs-Schutz

In Deutschland sind innerhalb nur einer Woche drei Wölfe zu Tode gekommen. Nachdem am vergangenen Freitag ein Wolf illegal in der sächsischen Lausitz geschossen wurde, starben zwei weitere Anfang dieser Woche durch Verkehrsunfälle: Bereits am Montag wurde ein Wolf auf einer Bundesstraße im nördlichen Sachsen-Anhalt überfahren, einen weiteren erwischte auf dem Berliner Ring in Brandenburg. Menschen kamen dabei nicht zu Schaden. Zuletzt war am 16. November ein Wolf bei einem Verkehrsunfall getötet worden – fast an identischer Stelle wie das Tier in Sachsen-Anhalt am Montag. (more…)

Bats: Virtually a model of flight

“Virtual Reality Design for Science” is a co-listed class at Brown and RISD that unites artists, designers, computer scientists, and experts in scientific visualization. The goal: to create tools for immersive interaction with scientific data. Test case for the course: the flight mechanics of bats.

PROVIDENCE, R.I. [Brown University] — If you want to get a good look at a bat, a cave is a pretty good place to go. But on a Thursday in mid-December at Brown’s Granoff Center, there were virtual bats flapping about in a cave of a different sort. (more…)
