A new study of sharks that lived in warm Arctic waters millions of years ago suggests that some shark species could handle the falling Arctic salinity that may come with rising temperatures.

The Arctic today is best known for its tundra and polar bear population, but roughly 38 to 53 million years ago during the Eocene epoch, the Arctic was like a huge temperate forest with brackish water, home to a variety of animal life, including ancestors of tapirs, hippo-like creatures, crocodiles and giant tortoises. Much of what is known about the region during this period comes from well-documented terrestrial deposits. Marine records have been harder to come by. (more…)

A Path toward More Powerful Tabletop Accelerators

Laser light needn’t be as precise as previously thought to drive new breed of miniature particle accelerators, say Berkeley Lab researchers.

Making a tabletop particle accelerator just got easier. A new study shows that certain requirements for the lasers used in an emerging type of small-area particle accelerator can be significantly relaxed. Researchers hope the finding could bring about a new era of accelerators that would need just a few meters to bring particles to great speeds, rather than the many kilometers required of traditional accelerators.

ANN ARBOR — A team of scientists from the University of Michigan, Duke Medicine and Stanford University has determined the underlying architecture of a cellular signaling complex involved in the body’s response to stimuli such as light and pain.

This complex, consisting of a human cell surface receptor and its regulatory protein, reveals a two-step mechanism that has been hypothesized previously but not directly documented. (more…)

Eine Erfindung aus Kassel könnte die Diagnostik von Krebserkrankungen und anderen Leiden vereinfachen, beschleunigen und kostengünstiger und exakter als bisherige Verfahren gestalten. Physiker und Biochemiker der Universität haben dafür eine neuartige Technikplattform entwickelt.

Diese Technikplattform kann mithilfe von „Fängermolekülen“ , einem durch Magnetfelder und magnetisierte kleinste Partikel gesteuerten Reinigungs- und Transportsystem sowie einem Sensor Indikatoren für das Vorhandensein eines bösartigen Tumors aus Blut oder Gewebeschnitten genau analysieren. Darauf haben die Wissenschaftler bereits ein europäisches Patent beantragt. (more…)

UD scientists sleuth out proteins involved in Crohn’s disease

University of Delaware researchers have identified a protein, hiding in plain sight, that acts like a bodyguard to help protect and stabilize another key protein, that when unstable, is involved in Crohn’s disease. The fundamental research points to a possible pathway for developing an effective therapy for the inflammatory bowel disease. (more…)

Atmosphärische Schwerewellen beeinflussen das Wetter und auch langfristig das Klimageschehen. Vom 29. Juni bis 23. Juli 2014 fliegt das Forschungsflugzeug Falcon des Deutschen Zentrums für Luft- und Raumfahrt (DLR) in mehreren Nächten über die Neuseeländischen Alpen, um mit moderner Lasermesstechnik und weiteren Instrumenten zu untersuchen, wie sich diese Wellen von der Erdoberfläche bis in 100 Kilometer Höhe ausbreiten. Die Ergebnisse sollen helfen, Klimamodelle sowie Wettervorhersagemodelle zu verbessern. (more…)
