Is there an ape for that? Orangutans plan trips - Salon.com - 0 views

  •  
    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.

Creature with Interlocking Gears on Legs Discovered | LiveScience - 0 views

  •  
    "Gears are ubiquitous in the man-made world, found in items ranging from wristwatches to car engines, but it seems that nature invented them first. A species of plant-hopping insect, Issus coleoptratus, is the first living creature known to possess functional gears, a new study finds. The two interlocking gears on the insect's hind legs help synchronize the legs when the animal jumps."

  •  
    "Als eine der Ursachen für die Ausbreitung multipler Antibiotika-Resistenzen gilt bereits der massive Einsatz von Antibiotika in der Massentierhaltung. In diesem Zusammenhang belegt eine statistische Studie aus den USA nun konkret: Wer in der Nachbarschaft zu einem Schweinemastbetrieb wohnt, hat ein erhöhtes Risiko für eine Infektion mit den multiresistenten Keimen.

@biogarage #gender Macht Arbeitslosigkeit /Männer/ alt? - @bdw-redaktion - 0 views

  •  
    "Die Forscher haben für ihre Studie die Länge der Telomere von 5.620 finnischen Frauen und Männern des Jahrgangs 1966 untersucht. Neben DNA-Proben hatten diese Personen auch Informationen über ihre Beschäftigungsverhältnisse abgegeben und ob und wie lange sie einmal arbeitslos gewesen waren. Die Auswertungen zeigten: Männer, die mindestens zwei Jahre lang arbeitslos gewesen waren, hatten doppelt so häufig signifikant verkürzte Teleomere als Männer, die durchwegs in Beschäftigung gewesen waren. Die Ergebnisse hielten auch statistischen Verfahren stand, die systematisch andere Faktoren ausschließen, die zu dem Ergebnis geführt haben könnten - beispielsweise der Gesundheitszustand, oder sozioökonomische Faktoren. Die Forscher fanden den Zusammenhang zwischen verkürzten Telomeren und Arbeitslosigkeit allerdings nicht bei den Frauen. Warum das so ist, bleibt unklar"

Skeletal remains of 24,000-year-old boy raise new questions about first Americans - 0 views

  •  
    Results from a DNA study of a young boy's skeletal remains believed to be 24,000 years old could turn the archaeological world upside down -- it's been demonstrated that nearly 30 percent of modern Native American's ancestry came from this youngster's gene pool, suggesting First Americans came directly from Siberia, according to a research team that includes a Texas A&M University professor.

  •  
    "Für ihre Studie verabreichten die Forscher Mäusen eine Substanz, die Reaktionen wie bei einer Infektion auslöst: Die Tiere aßen und tranken kaum und verloren schließlich an Körpergewicht. Bereits wenige Stunden nach dem Auslösen dieses experimentellen Krankheitszustandes belegten Untersuchungen, dass die Oberfläche des Dünndarms der Versuchstiere L-Fucose bildete. Dies stellten die Forscher nur im Rahmen der „krankheitsbedingten" Appetitlosigkeit fest. Normalerweise ist diese Zuckerform im Darm von Mäusen nämlich kaum nachweisbar."

MPG: Ana Catarina Miranda: Persönlichkeits-Typen werden vererbt - 0 views

  •  
    "Eine eindeutige Erklärung für diese Unterschiede in den Persönlichkeitstypen zwischen Stadt- und Landamseln haben die Wissenschaftler bis jetzt noch nicht. „Möglicherweise müssen Amseln in der schnelllebigen Stadtwelt permanent mit neuen Situationen zurechtkommen, wohingegen das Landleben mit seinen gleichförmigeren Abläufen verlässlichere Lebensbedingungen bietet", vermutet Catarina Miranda vom Max-Planck-Institut für Ornithologie in Radolfzell das Ergebnis. „Die Evolution scheint im Laufe der Besiedlung von Städten daher bestimmte Persönlichkeitstypen begünstigt zu haben", so Miranda. Diese Erklärung wird durch eine jüngst veröffentlichte Studie gestützt: Gene, die wahrscheinlich an der Ausprägung der hier untersuchten Verhaltensweisen beteiligt sind, zeigen in Stadtamseln eine andere Struktur als in den Waldamseln. Die Amselpersönlichkeit scheint also genetisch festgelegt und kann demnach durch Evolution während des Verstädterungprozesses verändert worden sein. ***** Ana Catarina Miranda, Holger Schielzeth, Tanja Sonntag & Jesko Partecke Urbanization and its effects on personality traits: a result of microevolution or phenotypic plasticity?, Global Change Biology, 19 June 2013 Max-Planck-Gesellschaft zur Förderung der Wissenschaften e.V. http://www.ncbi.nlm.nih.gov/pubmed/23681984"

Pinpoint Precision: Nanowires Deliver Biochemical Payloads to One Cell Among Many - 0 views

  •  
    "(PhysOrg.com) -- Imagine being able to drop a toothpick on the head of one particular person standing among 100,000 people in a stadium. It sounds impossible, yet this degree of precision at the cellular level has been demonstrated by researchers affiliated with the Johns Hopkins University Institute for NanoBioTechnology. Their study was published online in June in Nature Nanotechnology."

    "Until recently, the disastrous scale of the threat posed by salmon farms to the fauna and National Park of the Aysen region of southern Chile was entirely unknown. The unexpected discovery was made by researchers from the Max Planck Institute for Dynamics and Self-Organization and the University of Gottingen, who were studying acoustic communication among the native whales in the region."

Science Friday Archives: Meditation and the Brain - 1 views

  •  
    New research looks at the effects of studying a form of meditation on brain connectivity. Writing in the Proceedings of the National Academy of Science, researchers in China and the University of Oregon describe experiments on 45 students, some of whom were taught a meditation technique known as integrative body-mind training (IBMT). The researchers used brain imaging techniques to examine fibers connecting brain regions before and after training. Students trained in the IBMT approach for 11 hours or more appeared to develop new fibers in a part of the brain that helps a person regulate behavior. Control subjects did not form the new fibers. But what does the presence of those fibers actually mean -- and what is the meditation technique doing? We'll talk about it.
