ChemikerInnen entdecken neues Molekül zur Verbesserung der Synthese von Pharmazeutika

Das Molekül Cyclopropan wurde früher im Gemisch mit Sauerstoff als Narkosemittel verwendet. Ein internationales ForscherInnenteam rund um Nuno Maulide vom Institut für Organische Chemie der Universität Wien hat nun eine neue Art von Cyclopropanen entdeckt, die wesentlich vielseitiger und daher auch interessanter als Ausgangsbasis für die Entwicklung von Medikamenten und Agrochemikalien ist: Maulide gelang es, aus der ursprünglichen dreigliedrigen Ringstruktur des Moleküls eine Fünfringstruktur zu machen. Die Ergebnisse erscheinen aktuell im renommierten Fachmagazin Angewandte Chemie.

Vibrations make large landslides flow like fluid

New research shows why some large landslides travel greater distances across flat land than scientists would generally expect, sometimes putting towns and populations far from mountainsides at risk.

PROVIDENCE, R.I. and WEST LAFAYETTE, Ind. — A new study may finally explain why some landslides travel much greater distances than scientists would normally expect. A team of researchers used a sophisticated computer model to show that vibrations generated by large slides can cause tons of rock to flow like a fluid, enabling the rocks to rumble across vast distances.

Metal Foam Protects From Fire and Heat Twice as Well as Plain Metal

By Guest PostMay 25, 2016Scienceafsaneh rabiei, effective radiation shielding, fire, heat, metal foam, protect

A new study from North Carolina State University researchers finds that novel light-weight composite metal foams (CMFs) are significantly more effective at insulating against high heat than the conventional base metals and alloys that they’re made of, such as steel. The finding means the CMF is especially promising for use in storing and transporting nuclear material, hazardous materials, explosives and other heat-sensitive materials, as well as for space exploration.

Dissecting the animal diet, past and present

Researchers at Yale and the Smithsonian Institution say it’s time to settle a very old food fight.

In a study published March 18 in the journal Ecology and Evolution, authors Matt Davis and Silvia Pineda-Munoz argue that scientists need to focus as much on “when” animals eat as they do “what” animals eat. Without the proper time context, they say, an animal’s diet can tell very different stories. (more…)

From Near-Dropout to PhD, Berkeley Lab Scientist Now at Forefront of Biofuels Revolution

Berkeley Lab scientist Ee-Been Goh thrives on re-engineering bacteria and mentoring students.

To see biochemist Ee-Been Goh in the lab today, figuring out how to rewire bacteria to produce biofuels, one would never guess she was once so uninterested in school that she barely made it through junior high. (more…)

First-ever videos show how heat moves through materials at the nanoscale and speed of sound

Groundbreaking observations could help develop better, more efficient materials for electronics and alternative energy

Using a state-of-the-art ultrafast electron microscope, University of Minnesota researchers have recorded the first-ever videos showing how heat moves through materials at the nanoscale traveling at the speed of sound. (more…)

Diversity’s benefits

Solving difficult problems takes diverse teams, noted author says

“Hire the best people.” We’ve all heard that.

But often groups of “the best” — those with the highest abilities — don’t do the best job at solving a difficult problem, according to Scott Page, University of Michigan professor and author of The Difference, a classic book on the benefits of diversity. (more…)
