Findings by UCLA-led team hold promise for new ways to protect telecommunication and navigation satellites
New findings by a UCLA-led international team of researchers answer a fundamental question about our space environment and will help scientists develop methods to protect valuable telecommunication and navigation satellites. The research is published in the journal Nature Communications. (more…)
Einbau neuer Atome in das Erbgut hilft in der Krebsforschung
Nukleobasen bilden die Grundbausteine des Erbguts. Wenn man deren Sauerstoffatome durch Schwefel ersetzt und anschließend mit UV-Licht bestrahlt, wirken diese Nukleobasen als Photochemotherapeutikum. Durch die Kombination von experimentellen und theoretischen Untersuchungen ist es den ChemikerInnen um Leticia González von der Universität Wien gelungen, den molekularen Prozess hinter diesem Vorgang zu verstehen. Die neu gewonnenen Erkenntnisse können dazu beitragen, neue, noch effizientere Arzneistoffe zu entwickeln. Die Studie erscheint in der aktuellen Ausgabe von “Nature Communications”.
A new method for analyzing the chemical composition of stars may help scientists winnow the search for Earth 2.0.
Yale University researchers Debra Fischer and John Michael Brewer, in a new study that will appear in the Astrophysical Journal, describe a computational modeling technique that gives a clearer sense of the chemistry of stars, revealing the conditions present when their planets formed. The system creates a new way to assess the habitability and biological evolution possibilities of planets outside our solar system. (more…)
Im Zentrum des Vitamins B12 sitzt ein Kobaltatom. Dieses konnten britische Biologen und österreichische Chemiker nun durch ein anderes Metallion ersetzen – mit einem weiteren spektakulären Ergebnis: Das verwendete Rhodium passte besser in die B12-Struktur als das für die biologische Funktion des Vitamins essentielle Kobalt.

PORT HURON — It’s a perfect summer afternoon on the Saint Clair River, on the Canadian border just north of Detroit. Pleasure boats skim across the bright blue water as picnickers watch from the grassy bank. They don’t notice the fat black data cable that snakes out of the water, along a concrete pier and through a hole in the brick wall of an old papermill on the opposite riverbank. (more…)
Scientific studies are frequently the basis for news stories that seem too good to be true. How does the audience separate fact from fiction? The head of research at the UA explains. (more…)
Ions subjected to buffer gas cooling never truly reach the same temperature as the surrounding gas
According to the basic laws of thermodynamics, if you leave a warm apple pie in a winter window eventually the pie would cool down to the same temperature as the surrounding air. (more…)
ANN ARBOR — A new molecular gel recipe developed at the University of Michigan is at the core of a prototype for a more accurate lead paint test. (more…)
