Tübinger Forscher: Bei Experimenten mit dem COSY-Beschleuniger Quarks im Sechserpack nachgewiesen

Über Jahrzehnte haben Physiker vergeblich nach exotischen Bindungszuständen gefahndet, die aus mehr als drei Quarks bestehen. Wissenschaftler der Universität Tübingen waren an einem Experiment am Jülicher Beschleuniger COSY beteiligt, das nun zeigt: In der Natur kommen tatsächlich derartige komplexe Teilchen vor. Ihre Erkenntnisse hat die WASA-at-COSY Kollaboration in der Fachzeitschrift „Physical Review Letters“ veröffentlicht. (more…)

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…)

Michigan State University researchers have identified a genetic mutation in Doberman pinschers that causes albinism in the breed, a discovery that has eluded veterinarians and breeders worldwide up until now.

Paige Winkler, a doctoral student in the College of Veterinary Medicine, co-led the study with Joshua Bartoe, an assistant professor in the Department of Small Animal Clinical Sciences, and discovered a mutated gene that is associated with a form of albinism in humans. (more…)

Plants Send Out Signals Attracting Harmful Bacteria, MU Study Finds

Findings could lead to natural bacterial anti-infectives in food-producing plants

COLUMBIA, Mo. – When bacteria attack plants, they often inject harmful proteins into the host plants’ cells to weaken and suppress natural defenses. However, in some plants, bacteria attack once they’ve recognized the plant cells as a potential host. Now, researchers at the University of Missouri have identified and replicated the process that allows the bacteria—known mostly for attacking tomatoes—to invade its host. This discovery could lead to natural anti-infective treatments that work with food-producing plants to enhance resistance to harmful bacteria in the field. (more…)
