A multi-institutional team of engineers has developed a new approach to the fabrication of nanostructures for the semiconductor and magnetic storage industries. This approach combines top-down advanced ink-jet printing technology with a bottom-up approach that involves self-assembling block copolymers, a type of material that can spontaneously form ultrafine structures.

The team, consisting of nine researchers from the University of Illinois at Urbana-Champaign, the University of Chicago and Hanyang University in Korea, was able to increase the resolution of their intricate structure fabrication from approximately 200 nanometers to approximately 15 nanometers. A nanometer is a billionth of a meter, the width of a double-stranded DNA molecule. (more…)

The Black tents that defied a nation

A beach umbrella and a tent formed an unlikely Embassy, pitched on the lawns of the Australian Parliament on Australia Day 1972, by four Aboriginal activists. The Aboriginal Embassy was an ingenious response following a poorly-timed policy statement in which a conservative Prime Minister rejected Aboriginal land rights. (more…)

Nächste Woche wird der sogenannte IPCC-Bericht in Schweden vorsgestellt. 800 Wissenschaftler haben daran gearbeitet. 1000 Seiten aktuelle Klimafoschung sind das Ergebnis. Alle wichtigen Klimaexperten der Welt werden die Ergebnisse und den Stand der Klimaforschung in Stockholm diskutieren. Greenpeace-Klimaexperte Karsten Smid erklärt, was IPCC bedeutet und was er von dem Gipfeltreffen der Klimaexperten erwartet.

Online-Redaktion: Was ist der IPCC?

Karsten Smid: Im Weltklimarat IPCC (Zwischenstaatlicher Ausschuss für Klimaänderungen) finden sich Wissenschaftler aus der ganzen Welt zusammen, die den aktuellen Wissensstand zur Klimaforschung zusammentragen und bewerten. Er wurde im November 1988 vom Umweltprogramm der Vereinten Nationen (UNEP) und der Weltorganisation für Meteorologie (WMO) als zwischenstaatliche Institution gegründet. Der IPCC betreibt selbst keine Forschung, sondern trägt die Ergebnisse der Forschungen in den verschiedenen Disziplinen zusammen. Er wurde 2007, gemeinsam mit dem ehemaligen US-Vizepräsidenten Al Gore, mit dem Friedensnobelpreis ausgezeichnet. (more…)

First in state to perform minimally invasive alternative to open-heart surgery

Todd Dunlap, 62, arrived at Ronald Reagan UCLA Medical Center’s emergency room on Aug. 8 suffering from shortness of breath, fatigue and extreme cold. When a CT scan revealed a 24-inch clot stretching from his legs into his heart, doctors feared the mass could break loose and lodge in his lungs, blocking oxygen and killing him instantly.

Missouri trends mirror the national picture; MU scientist offers policy suggestions to fight hunger issues

COLUMBIA, Mo. – The 2013 Missouri Hunger Atlas, issued by the University of Missouri’s Interdisciplinary Center for Food Security, shows that more than one in five Missouri households with children are food insecure, meaning they worry about not having enough food. One author of the Hunger Atlas said that patterns in Missouri reflect what is happening at the national level, and offers suggestions for actions from government policy makers and individuals to provide some relief.

NABU-Kernforderungen zur Bundestagswahl 2013

Kernforderungen des NABU für die Umwelt- und Naturschutzpolitik in der nächsten Legislaturperiode des Deutschen Bundestags.

1. Biologische Vielfalt wirksam schützen

Das Ziel, den Verlust der biologischen Vielfalt bis zum Jahr 2010 zu stoppen, ist klar gescheitert und durch die europäischen Staats- und Regierungschefs auf 2020 verschoben worden. Um dieses Ziel nun tatsächlich erreichen zu können, muss das Bundesprogramm Biologische Vielfalt finanziell gestärkt und bis zum Jahr 2016 auf ein Volumen von 100 Millionen Euro aufgestockt werden. Das Programm ist zudem so zu entwickeln, dass die relevanten Akteure bei der Umsetzung prioritärer und besonders dringlicher Naturschutzaufgaben wirksam unterstützt werden können. (more…)
