Wenn Blutplättchen Hautkrebs eskalieren lassen

ChemikerInnen der Universität Wien analysieren Krankheitsmechanismen beim Melanom

Die Krebstherapie beim Melanom hat in den letzten Jahren große Fortschritte gemacht. Dennoch kommt es immer wieder zur Ausbildung von Resistenzen, die zu einer fatalen Eskalation der Krankheit und letztlich zum Tod führen können. Dem Chemiker Christopher Gerner von der Universität Wien ist es durch die Analyse von Serumproben gelungen, Blutplättchen als wichtige Akteure in der Eskalation des Melanoms zu identifizieren. Die aktuellen Erkenntnisse wurden im amerikanischen Fachjournal “Molecular Cellular Proteomics” publiziert.

Yale’s legacy in ‘Jurassic World’

On a summer evening in 1993, Professor John Ostrom, a paleontologist at the Yale Peabody Museum of Natural History, had a chance to see one of his discoveries spring to life.

“Jurassic Park,” Steven Spielberg’s film adaptation of Michael Crichton’s bestselling novel, was setting box-office records. Both the filmmaker and the novelist had consulted Ostrom. The tale’s primary dinosaur antagonists, the vicious Velociraptors, were based on Deinonychus — a Cretaceous predator whose fossilized remains Ostrom discovered in Montana in 1964. (more…)

Were Dinosaurs Cold-Blooded or Warm-Blooded? Neither, Study Finds

A study that originated in the lab of UA biologist Brian J. Enquist with UA alum John Grady suggests dinosaurs had a metabolism that was neither warm- nor cold-blooded, but somewhere in between.

Dinosaurs dominated the Earth for more than 100 million years, but all that remains today are bones. This has made it difficult to solve a long-standing and contentious puzzle: Were dinosaurs cold-blooded animals that lumbered along or swift warm-blooded creatures like those depicted in “Jurassic Park”?  (more…)
