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…)
Soon after Donald Trump’s victory, protests started on streets in many US cities and on internet against a democratically elected man. It’s unbelievable. But it’s the true face of Hillary Clinton and her supporters. They still can’t accept the results. (more…)
