ANN ARBOR — An entrepreneur’s backstory plays a critical role in the success or failure of a fledgling venture, says Lianne Lefsrud, a postdoctoral fellow at the University of Michigan Ross School’s Erb Institute.
“Especially for entrepreneurs with limited financial resources, stories are a way to create resources if you can make sense of the world with your stories,” Lefsrud said. (more…)
High-Fiber Salad Bar May Help Lagomorphs Survive Climate Change
In some mountain ranges, Earth’s warming climate is driving rabbit relatives known as pikas to higher elevations or wiping them out. But University of Utah biologists discovered that roly-poly pikas living in rockslides near sea level in Oregon can survive hot weather by eating more moss than any other mammal.
“Our work shows pikas can eat unusual foods like moss to persist in strange environments,” says biology professor Denise Dearing, senior author of the new study, published online on Dec. 18, 2013 in the February 2014 issue of Journal of Mammalogy. “It suggests that they may be more resistant to climate change than we thought.” (more…)
WWF-Sonderpreis bei „GreenTec Awards 2014“ / Online-Voting für innovative Naturschutzprojekte
Im Rahmen der GreenTec Awards 2014 wird erstmalig ein WWF Sonderpreis für Naturschutzarbeit verliehen. Vom 04.01. bis 13.02.14 können User per Online-Voting unter www.greentec-awards.com aus zehn innovativen, deutschen Naturschutzprojekten den persönlichen Favoriten wählen. Von der Besenderung eines Wisents über den Schutz von Fledermauskolonien bis hin zur Teich-Renaturierung reicht die Bandbreite der Kandidaten. Das Gewinnerprojekt wird im Rahmen der GreenTec Awards-Gala im Mai 2014 ausgezeichnet.
„Naturschutz fängt vor der eigenen Haustür an und jedes der zehn Projekte hat einen Vorbildcharakter für ehrenamtliche Naturschutzarbeit in Deutschland und Europa“, sagt Marco Vollmar, Mitglied der Geschäftsleitung beim WWF Deutschland. (more…)
This holiday season, feast your eyes on images of Saturn and two of its most fascinating moons, Titan and Enceladus, in a care package from NASA’s Cassini spacecraft. All three bodies are dressed and dazzling in this special package assembled by Cassini’s imaging team.
The new images are available online at: https://www.nasa.gov/cassini , https://saturn.jpl.nasa.gov and https://ciclops.org .
“During this, our tenth holiday season at Saturn, we hope that these images from Cassini remind everyone the world over of the significance of our discoveries in exploring such a remote and beautiful planetary system,” said Carolyn Porco, Cassini imaging team leader, based at the Space Science Institute, Boulder, Colo. “Happy holidays from all of us on Cassini.” (more…)
Die Europäische Union durchlebt die wohl schwerste Krise. Doch es gibt auch eine positive Botschaft: Europa wächst zusammen.
In der Ukraine demonstrieren Bürgerinnen und Bürger für eine Annäherung ihres Landes an die Europäische Union, Anfang Jahr beginnen die Beitrittsverhandlungen der EU mit Serbien – und am 1. Januar 2014 fällt wieder einmal eine Grenze: Die Übergangsregeln für die EU-Staaten Rumänien und Bulgarien laufen aus, die Bürgerinnen und Bürger dieser beiden Länder kommen ab Jahresanfang in den Genuss der vollen Personenfreizügigkeit der EU (für die Schweiz gelten noch bis Mai 2016 Beschränkungen). Trotz weiterhin bestehender Strahlkraft der EU, trotz fallender Grenzen: Zum Feiern ist niemandem zumute. (more…)
From tomatoes to pumpkins, most fruit and vegetable crops rely on pollination by bees and other insect species – and the future of many of those species is uncertain. Now researchers from North Carolina State University are proposing a set of guidelines for assessing the performance of pollinator species in order to determine which species are most important and should be prioritized for protection.
“Widespread concerns over the fate of honey bees and other pollinators have led to increased efforts to understand which species are the most effective pollinators, since this has huge ramifications for the agriculture industry,” says Dr. Hannah Burrack, an associate professor of entomology at NC State and co-author of a paper on the new guidelines and related research. “However, various research efforts have taken a wide variety of approaches, making it difficult to compare results in a meaningful way.

A research team led by UA anthropologist David Raichlen has found that the Hadza tribe’s movements while foraging can be described by a mathematical pattern called a Lévy walk – a pattern that also is found in the movements of many other animals
A mathematical pattern of movement called a Lévy walk describes the foraging behavior of animals from sharks to honey bees, and now for the first time has been shown to describe human hunter-gatherer movement as well. The study, led by University of Arizona anthropologist David Raichlen, was published on December 23, 2013 in the Proceedings of the National Academy of Sciences. (more…)
Hacking the Earth’s climate to counteract global warming – a subject that elicits strong reactions from both sides – is the topic of a December special issue of the journal Climatic Change. A dozen research papers include the most detailed description yet of the proposed Oxford Principles to govern geoengineering research, as well as surveys on the technical hurdles, ethics and regulatory issues related to deliberately manipulating the planet’s climate.
