A sweeter way to make green products
Researchers invent novel process for extracting sugars from wood
The shampoo you washed your hair with this morning. The balloons for the party. Refrigerators and sunglasses, medicine and mosquito repellent, guitar strings and fishing lures. These — and thousands of other products we use every day — contain chemicals made from petroleum. But researchers at the University of Delaware can now offer manufacturers a much sweeter alternative to this fossil fuel. (more…)
Wissenschaftler entwickeln Anlage zu besseren Regulierung von Blindstrom in Stromnetzen
Zwei Wissenschaftler der Uni Kassel wollen eine 80 Jahre alte Technik nutzen, um mehr Erneuerbare Energien in die Stromnetze einspeisen zu können. Die Forscher vom Fachgebiet Elektrische Energieversorgungssysteme entwickeln einen neuen Typ sogenannter Kompensationsanlagen, mit denen die Blindleistung in Netzen reguliert wird. (more…)

Scholars take aim at false positives in research
UChicago professor argues for lowering key statistical benchmark
A single change to a century-old statistical standard would dramatically improve the quality of research in many scientific fields, shrinking the number of so-called false positives, according to a commentary published Sept. 1 in Nature Human Behaviour. (more…)
Signalwege verstehen, Ausbreitung von Tumoren bekämpfen
Sonderforschungsbereich der Universität Freiburg geht in die dritte und finale Förderphase
Die Deutsche Forschungsgemeinschaft (DFG) hat den Fortsetzungsantrag des Sonderforschungsbereichs (SFB) 850 „Kontrolle der Zellmotilität bei Morphogenese, Tumorinvasion und Metastasierung“ bewilligt. Der SFB 850 läuft seit dem 1. Januar 2010 und geht Anfang 2018 in seine dritte und finale Förderphase. (more…)

Experiments with levitated nanoparticles reveal role of friction at the nanoscale
Transitions occurring in nanoscale systems, such as a chemical reaction or the folding of a protein, are strongly affected by friction and thermal noise. Almost 80 years ago, the Dutch physicist Hendrik Kramers predicted that such transitions occur most frequently at intermediate friction, an effect known as Kramers turnover. (more…)
UCLA research reveals how new behaviors appear and spread among capuchin monkeys
One white-faced capuchin monkey sticks its fingers deep into the eye sockets of another capuchin it’s friends with. A capuchin uses her ally’s body parts to whack their common enemy. These behaviors become entrenched in the repertoires of the inventors. But in the first case, the behavior spreads to other group members, and in the second case it does not. (more…)
