Growing inequalities make science more of a ‘winner takes all’ field

ANN ARBOR — As new research documents growing inequalities in health and wealth, the gap between “haves” and “have-nots” is growing in the field of scientific research itself, says University of Michigan sociologist Yu Xie.

“It’s surprising that more attention has not been paid to the large, changing inequalities in the world of scientific research, given the preoccupation with rising social and economic inequality in many countries,” said Xie, research professor at the U-M Institute for Social Research and professor of sociology, statistics and public policy.

Twenty years after the hormone leptin was found to regulate metabolism, appetite, and weight through brain cells called neurons, Yale School of Medicine researchers have found that the hormone also acts on other types of cells to control appetite.

Published in the June 1 issue of Nature Neuroscience, the findings could lead to development of treatments for metabolic disorders such as obesity and diabetes. (more…)

Scientists from the Camborne School of Mines have conducted a ground-breaking analysis of a Martian meteorite that dates back to the formation of the Earth

Dr Gavyn Rollinson used pioneering technology to map the mineralogy of a section of the meteorite – which was discovered in North Africa and is around 4.4 billion years old. (more…)

For Earth Day this year, NASA invited people around the world to step outside to take a “selfie” and share it with the world on social media. NASA released Thursday a new view of our home planet created entirely from those photos.

The “Global Selfie” mosaic was built using more than 36,000 individual photographs drawn from the more than 50,000 images tagged #GlobalSelfie and posted on or around Earth Day, April 22, on Twitter, Instagram, Facebook, Google+ and Flickr. The project was designed to encourage environmental awareness and recognize the agency’s ongoing work to protect our home planet. (more…)

Amphibians in a vise: Climate change robs frogs, salamanders of refuge

By hightailing it to nearby ponds and shallow waterways, frogs and salamanders have – until now – had a way to evade exotic trout introduced to the West’s high-mountain lakes for recreational fishing.

A warming climate, however, will dry up some of the places where amphibians and their young have found refuge. Researchers in the May 1 issue of Frontiers in Ecology and the Environment write about this challenge and a novel combination of tools that could help land managers, biologists, fishing enthusiasts and other citizens weigh where amphibians are in the most need of help and guide plans for possible fish removals from selected lakes.

Kältekünstler Mammut und Co

Eiszeitforscher Prof. Dr. Ralf-Dietrich Kahlke von der Senckenberg Forschungsstation für Quartärpaläontologie in Weimar hat den Ursprung der eurasischen Mammutfauna anhand von Fossilien aus über 500 Fundstellen rekonstruiert. Er kommt zu dem Schluss, dass nicht allein die globale Klimaabkühlung, sondern ein Zusammenspiel verschiedener Faktoren die Entstehung und weite Ausbreitung der Mammutfauna verursachte. Die Studie ist online im Fachjournal „Quaternary Science Reviews“ erschienen.

Wer an Mammuts denkt, hat sofort schneebedeckte Landschaften im Kopf – und tatsächlich gehörten die Eiszeitriesen zu den am besten an Kälte angepassten Säugetieren in der Erdgeschichte. Doch die entfernten Verwandten heutiger Elefanten bevölkerten einst – gemeinsam mit anderen eiszeitlichen Großtieren, wie Moschusochsen, Fellnashörnern, Saiga-Antilopen und Rentieren – sehr viel weitere Areale, als man vermuten würde.
