Consumers “forget” when products have ethical issues
COLUMBUS, Ohio — Many consumers have found a way to cope with the knowledge that products they like have been made unethically: They simply forget they ever knew it. (more…)
Eine Form des Vitamins kurbelt den Energiestoffwechsel in Nervenzellen an und schützt sie vor dem Absterben, berichten Tübinger Forscher. Der Wirkstoff könnte einen möglichen Therapieansatz darstellen.
Zittrige Hände, steife Muskeln und verlangsamte Bewegungen – das sind die typischen Symptome der Parkinsonerkrankung. Rund 220.000 Personen sind in Deutschland von der Krankheit betroffen, die zunehmend mit steigendem Alter auftritt. Sie beruht auf dem Verlust von Nervenzellen im Gehirn und ist bislang nicht heilbar. (more…)
Study could improve self-assembling structures like heart stents and satellite solar panels
Scientists and engineers are fascinated by self-folding structures. Imagine the possibilities: Heart stents that unfold in the right location or pop-up tents that assemble at the press of a button, as well as nanoscale versions for tiny machines. But sometimes these structures get stuck during the folding process, and scientists don’t know why. (more…)
According to ADrugRehab.org, “Addiction is tricky and calculating, and it’s the only disease that can take more than one person down with it, if it is left unchallenged. Addiction dramatically alters the lives of not just the addicted person, but of everyone within his or her vicinity, namely family and friends.” If you believe that a loved one is showing signs of succumbing to addiction, you’ll want to act as soon as possible.

Sparsam und wirtschaftlich: Wie Effizienz als verfassungsrechtlicher Begriff und das Wesen der Demokratie zusammengehen, erforscht die Juristin Maria Bertel. Wie können staatliche Aktionen gemessen und beurteilt werden? (more…)
Someone I know was in a minor car crash recently. The car was hit from behind by a driver who was using a cellphone, causing damage to both vehicles, but nobody was hurt. The police were called, and though the officer was told that the driver who caused the crash was using a cellphone, no tickets were issued. The officer left without filing any kind of accident report. (more…)
Nanokristalle beeinflussen die Differenzierung von Stammzellen während der Knochenbildung
Wissenschaftlerinnen und Wissenschaftler der Universitäten Freiburg und Basel haben einen Hauptschalter für die Regeneration von Knochengewebe identifiziert. Prof. Dr. Prasad Shastri, Professor für Biofunktionale Makromolekulare Chemie am Institut für Makromolekulare Chemie und Professor für Cell Signalling Environments im Exzellenzcluster BIOSS Centre for Biological Signalling Studies der Universität Freiburg, hat die Studie geleitet. Das Team hat seine Resultate im Fachjournal „Proceedings of the National Academy of Sciences – USA“ (PNAS) veröffentlicht. (more…)
At the core of the system is the ability to sense a miner’s location and body temperature, predict potential problems and recommend steps to avert health risks.
University of Arizona startup GUIA has licensed a mining communication and sensor platform developed by faculty in the UA’s College of Engineering and Lowell Institute for Mineral Resources. While the team’s initial focus for this “internet of things” system is mining, the company is looking to apply the technology to a number of other environments. (more…)
