An experimental cancer drug that has shown promise in the treatment of melanoma has also shown early potential as an effective treatment for patients with non-small cell lung cancer, the leading cause of cancer death among men and women worldwide.

Dr. Edward Garon, director of thoracic oncology at UCLA’s Jonsson Comprehensive Cancer Center, presented the preliminary results of a Phase 1B study of the new drug, called MK-3475, on Oct. 29 at the World Conference on Lung Cancer in Sydney, Australia. (more…)

Hamburg/St. Petersburg, 15. 11. 2013 – Die russischen Ermittlungsbehörden haben heute angekündigt, einen Antrag auf Verlängerung der Untersuchungshaft für die in Russland inhaftierten 28 Greenpeace-Aktivisten und zwei Journalisten zu stellen. Die sogenannten Arctic 30 sollen drei weitere Monate in Untersuchungshaft bleiben. Die Anträge sollen in der kommenden Woche vor Gericht verhandelt werden.

Bislang sind beim zuständigen Kalininsky Bezirksgericht sechs Anträge auf Verlängerung eingegangen. Greenpeace erwartet, dass heute und am Montag weitere Anträge folgen.

Den Anwälten der Greenpeace-Aktivisten wurde mitgeteilt, dass die Ermittlungsbehörde die Haft um drei Monate verlängern will, um weitere Untersuchungen durchzuführen. Sollte das Gericht dieses abweisen, müssen die Inhaftierten freigelassen werden. (more…)

NASA Helps Melt Secrets of Great Lakes Ice

Two scientists from NASA and NOAA have developed a new space-based technique for monitoring the ice cover of the Great Lakes that is so accurate it can identify a narrow channel of open water cut through the ice by an icebreaker — even at night.

“In the dark, it’s difficult to read a map that’s right in front of you,” said Son Nghiem of NASA’s Jet Propulsion Laboratory, Pasadena, Calif., one of the developers of the new technique. “Yet we now have a way to use satellite radars almost 500 miles [800 kilometers] out in space to see through clouds and darkness and map ice across the Great Lakes.” (more…)

Lack of cyber security skills a major inhibitor to adoption of emerging technologies like cloud, mobile, cognitive and social networks

ARMONK, N.Y – 15 Nov 2013: IBM today announced that it is adding eleven additional schools to its more than 200 partnerships with universities around the globe, focusing on collaborating to bring cyber security skills into the classroom. According to the U.S. Bureau of Labor Statistics employment in the cyber security field is expected to grow rapidly, increasing 22 percent by 2020. As organizations transmit and store more sensitive information electronically, the need for employees with experience in cyber security will be imperative in order to protect data in the cloud, mobile devices and traditional computing.

Research provides new insights into bone biology

Bone marrow, the spongy tissue inside long bones, produces new blood cells and helps the lymphatic system work properly. But it may also turn out to be a progressively hostile microenvironment that induces vascular dysfunction and ossification, or hardening, of blood vessels.

Rhonda Prisby, who is using a rat model to study bone vascular physiology and morphology, was recently surprised when she used light microscopy to look at bone marrow vessels. (more…)

RWE auf AKW-Risikokurs: AKW Gundremmingen verstößt gegen Sicherheitsvorschriften

Das Atomkraftwerk Gundremmingen in Bayern weist nach einer Studie des ehemaligen Leiters der deutschen Atomaufsicht, Professor Wolfgang Renneberg, gravierende Sicherheitsmängel auf. Dennoch hat der AKW-Betreiber RWE eine Leistungsausweitung der beiden Siedewasserreaktoren beantragt, über deren Genehmigung in den kommenden zwei Wochen entschieden werden könnte.

Wolfgang Renneberg, Professor am Institut für Sicherheits- und Risikowissenschaften der Universität für Bodenkultur Wien, listet mit großer Detailkenntnis Probleme beim Reaktor und bei dem Genehmigungsverfahren zur Leistungserhöhung auf. Besonders bedenklich: Das AKW Gundremmingen hat nicht die von den kerntechnischen Sicherheitsregeln geforderten ausreichenden Notkühlsysteme. Auch ist die Atomanlage nicht gegen den Absturz heutiger großer Verkehrsflugzeuge ausgelegt. Schon der jetzige Betrieb verstößt erheblich gegen kerntechnische Sicherheitsvorschriften. Die Leistungsausweitung kann nach geltenden Vorschriften nicht genehmigt werden. (more…)

Mutual benefits: Stressed-out trees boost sugary rewards to ant defenders

ANN ARBOR — When water is scarce, Ecuador laurel trees ramp up their investment in a syrupy treat that sends resident ant defenders into overdrive, protecting the trees from defoliation by leaf-munching pests.

The water-stressed tropical forest trees support the production of more honeydew, a sugary excretion imbibed by the Azteca ants that nest in the laurels’ stem cavities. In return, ant colonies boost their numbers and more vigorously defend the life-sustaining foliage. (more…)
