Puget Sound hosts more than 100 species of seabirds, 200 species of fish, 15 marine mammal species, hundreds of plant species, and thousands of invertebrate species. These species do not exist in isolation, but rather interact with each other in a variety of ways: they eat and are eaten by each other;

dass bei Mäusen mindestens 2 der 3 zur Krebstherapie zugelassenen Angiogenese-Hemmer die Bösartigkeit von Tumoren erhöhen können (Cancer Cell 2009, Band 15: Seite 220 und 232). Wurden krebskranke Labortiere mit den Wirkstoffen Sunitinib oder Sorafenib behandelt, verlangsamte sich einerseits das Tumorwachstum deutlich, andererseits drangen die Tumore verstärkt in das umliegende Gewebe ein und bildeten mehr Metastasen. .. Offenbar verlangsamen Angiogenese-Hemmer zunächst das Wachstum eines Tumors, bis dieser auf das knappe Nährstoffangebot reagiert und sich gegen das Aushungern zur Wehr setzt. „Möglicherweise liegt das daran, dass ein Tumor sein Wachstumsverhalten ändert, wenn er nicht mehr ausreichend versorgt wird. Indem er in benachbartes Gewebe eindringt und Tochtergeschwülste bildet, könnte er versuchen, wieder mehr Nachschub zu bekommen

"Feilschen ähnelt einem sportlichen Wettkampf. Vor allem insofern, als der besser trainierte Teilnehmer in der Regel als Sieger aus dem Duell geht. Ein wertvoller Tipp zur Vorbereitung für den nächsten Besuch auf dem Basar kommt nun von Psychologen um David Loschelder von der Universität Saarbrücken: Um einen guten Preis zu erzielen, sollte man eine krumme Summe als Angebot aufrufen. Wer etwa ein Auto verkauft, sollte nicht mit einem runden Betrag ins Rennen gehen, sondern zum Beispiel 14.885 oder 15.225 Euro verlangen. Ein solcher, scheinbar präzise abgewogener Preis erzeuge nämlich die Illusion, dass der Verkäufer besonders gut informiert sei. Das beeindruckt beim Handeln"

What he and his orangutan buddies do in the forests of Sumatra tells scientists that advance trip planning and social networking aren't just human traits, A new study of 15 wild male orangutans finds that they routinely plot out their next day treks and share their plans in long calls, so females can come by or track them, and competitive males can steer clear.

A giant asteroid smashing into Earth is the only plausible explanation for the extinction of the dinosaurs, a global scientific team said on Thursday, hoping to settle a row that has divided experts for decades. A panel of 41 scientists from across the world reviewed 20 years' worth of research to try to confirm the cause of the so-called Cretaceous-Tertiary (KT) extinction, which created a "hellish environment" around 65 million years ago and wiped out more than half of all species on the planet. Scientific opinion was split over whether the extinction was caused by an asteroid or by volcanic activity in the Deccan Traps in what is now India, where there were a series of super volcanic eruptions that lasted around 1.5 million years. The new study, conducted by scientists from Europe, the United States, Mexico, Canada and Japan and published in the journal Science, found that a 15-kilometre (9 miles) wide asteroid slamming into Earth at Chicxulub in what is now Mexico was the culprit. "We now have great confidence that an asteroid was the cause of the KT extinction. This triggered large-scale fires, earthquakes measuring more than 10 on the Richter scale, and continental landslides, which created tsunamis," said Joanna Morgan of Imperial College London, a co-author of the review.

"A large study from Children's Hospital Boston and the Boston-based Autism Consortium finds that a genetic test that samples the entire genome, known as chromosomal microarray analysis, has about three times the detection rate for genetic changes related to autism spectrum disorders (ASDs) than standard tests. Publishing in the April issue of Pediatrics (and online March 15), the authors urge that CMA become part of the first-line genetic work-up for ASDs."

Life must have begun with a simple molecule that could reproduce itself - and now we think we know how to make one

Shortly before his 80th birthday, on September 15, the physics Nobel laureate Murray Gell-Mann spoke with Science News Editor in Chief Tom Siegfried about his views on the current situation in particle physics and the interests he continues to pursue in other realms of science.

"The creation of E-ZPass lanes over the past 15 years has significantly improved the health of newborn babies living near highways in the Northeast, according to a Columbia study. The researchers found that reductions in traffic congestion generated by E-ZPass lanes reduced premature birthrates by 10.8 percent and low birth weight by 11.8 percent among infants born within 2 kilometers of toll plazas. The net effect has led to hundreds of millions of dollars in saved medical costs."

"Studien haben zudem gezigt, dass Männer Frauen, die rote Kleidung tragen, sexuell besonders attraktiv finden - und das offenbar in vielen verschiedenen Kulturen: Auch Männer aus einer ziemlich isoliert lebenden Dorfgemeinschaft in Burkina Faso reagieren ähnlich auf Rot - und das, obwohl die Farbe dort sonst eigentlich mit negativen Assoziationen verbunden ist."

To see if quantum processes play a role in determining the shape of DNA, Elisabeth Rieper of the National University of Singapore and colleagues modelled each base pair as a cloud of electrons that oscillates around a positively charged nucleus. The team found that quantum entanglement between these clouds helped DNA to maintain its helical structure.

Amazing what can be made from a bit of background noise in the GEO600 with a bit of imagination (or desire). Intriguing article from 12 months ago. No new information since....
