Scholars say that, overall, gun violence can be reduced by instituting a risk-based approach to firearms possession and purchases

Recent mass killings in Isla Vista, California, and elsewhere have again raised concern among lawmakers and the media about the possible connection between mental illness and gun violence. A new study sets the record straight and recommends an evidence-based approach to limiting firearms fatalities. (more…)

Understanding the Ocean’s Role in Greenland Glacier Melt

The Greenland Ice Sheet is a 1.7 million-square-kilometer, 2-mile thick layer of ice that covers Greenland. Its fate is inextricably linked to our global climate system.

In the last 40 years, ice loss from the Greenland Ice Sheet increased four-fold contributing to one-quarter of global sea level rise. Some of the increased melting at the surface of the ice sheet is due to a warmer atmosphere, but the ocean’s role in driving ice loss largely remains a mystery. (more…)

NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) has captured an extreme and rare event in the regions immediately surrounding a supermassive black hole. A compact source of X-rays that sits near the black hole, called the corona, has moved closer to the black hole over a period of just days. (more…)

WWF startet Tattoo-Kampagne / Motive zeigen bedrohte Tierarten

Berlin/Moskau – Diese Aktion geht unter die Haut: Um auf den weltweiten Artenschwund aufmerksam zu machen, hat der WWF Russland eine Tattoo-Kampagne ins Leben gerufen. Hierzu haben sich die Umweltschützer mit 14 bekannten Tattoo-Künstlern zusammengetan, von denen jeder ein Motiv einer bedrohten Tierart entwickelt hat. Alle Interessierten, die sich eine der Vorlagen stechen lassen möchten, können sich bis zum 1. September unter www.wildtattoo.ru/en bewerben und sich so die Chance auf eines der Tiere sichern. Das Besondere: Jedes Motiv wird nur einmal gestochen. Die Auserwählten können sich somit über ein echtes Unikat auf ihrer Haut freuen. (more…)

Biofilme im Bachnetzwerk der Ybbs analysiert

Ein interdisziplinäres Forschungsteam rund um den Limnologen Tom J. Battin von der Universität Wien zeigt erstmals, dass die Organisation mikrobieller Lebensgemeinschaften von der Organisation der Umwelt, in der die Mikroorganismen leben, beeinflusst wird. Die WissenschafterInnen sequenzierten dazu die DNA von Biofilmen aus 114 Bächen im Einzugsgebiet der Ybbs und errechneten über Netzwerkanalysen das Gefüge der mikrobiellen Gemeinschaften. Ihre Ergebnisse publizieren sie in der renommierten Fachzeitschrift PNAS. (more…)

Fertility: Sacrificing eggs for the greater good

A woman’s supply of eggs is a precious commodity because only a few hundred mature eggs can be produced throughout her lifetime and each must be as free as possible from genetic damage. Part of egg production involves a winnowing of the egg supply during fetal development, childhood and into adulthood down from a large starting pool. New research by Carnegie’s Alex Bortvin and postdoctoral fellow Safia Malki have gained new insights into the earliest stages of egg selection, which may have broad implications for women’s health and fertility. The work is reported in the early on-line edition of Developmental Cell. (more…)

Bilanz nach fünf Jahren Wald- und Klimaschutz in Indonesien

„Harapan“ lautet das Motto eines nun auslaufenden Klimaschutzprojektes auf der indonesischen Insel Sumatra. „Harapan“ bedeutet in der Landessprache „Hoffnung“. Das Projekt, das aus Mitteln der Internationalen Klimainitiative (IKI) des deutschen Bundesumweltministeriums (BMUB) gefördert wurde, gilt als Leuchtturm-Vorhaben im Tropenwaldschutz. Die knapp 100.000 Hektar große Region beherbergt einen der letzten Tieflandregenwälder Sumatras und ist eine Insel in einem Meer von Ölpalmen. (more…)

Mathematical framework: How a wrinkle becomes a crease

Kyung-Suk Kim and Mazen Diab have worked out the mathematics of how wrinkles form in solid materials under compression — and how, under more compression, those wrinkles can become creases. The mathematics of wrinkles and creases could help in the design of flexible electronic circuits, artificial skin, and soft robotic grips and may help explain brain injuries due to compression.

PROVIDENCE, R.I. [Brown University] — Wrinkles, creases and folds are everywhere in nature, from the surface of human skin to the buckled crust of the Earth. They can also be useful structures for engineers. Wrinkles in thin films, for example, can help make durable circuit boards for flexible electronics. (more…)
