Where the Wild Stars Are

By Guest PostFebruary 1, 2014Sciencegas, generations of stars, micron light, NASA, neowise, trifid nebula, visible light views, wild stars, wise, young stars

A storm of stars is brewing in the Trifid nebula, as seen in this view from NASA’s Wide-field Infrared Survey Explorer, or WISE. The stellar nursery, where baby stars are bursting into being, is the yellow-and-orange object dominating the picture. Yellow bars in the nebula appear to cut a cavity into three sections, hence the name Trifid nebula.

Colors in this image represent different wavelengths of infrared light detected by WISE. The main green cloud is made up of hydrogen gas. Within this cloud is the Trifid nebula, where radiation and winds from massive stars have blown a cavity into the surrounding dust and gas, and presumably triggered the birth of new generations of stars. Dust glows in infrared light, so the three lines that make up the Trifid, while appearing dark in visible-light views, are bright when seen by WISE. (more…)

What we don’t know: Neuroscience research at CMHC

The third floor of the CMHC houses the Clinical Neuroscience Research Unit (CNRU), an inpatient and outpatient research facility. It’s an honor to be asked to start a dialogue with you about what we do on the CNRU. Over the next few months, I’d like to introduce you to the scientists and clinicians and their teams that work on the CNRU. Today I’d like to introduce you to some of the things we do on the 3^rd floor. (more…)

Vibrations influence the circadian clock of a fruit fly

The internal circadian clock of a Drosophila (fruit fly) can be synchronised using vibrations, according to research published today in the journal Science. The study suggests that an animal’s own movements can influence its clock.

The circadian clock, which underlies the daily rhythms characterising most of our bodily functions, including the sleep cycle, is mainly set by diurnal changes in light and temperature. (more…)

Was uns im Februar so blühen kann !

Zum Beispiel die Haselnuss, die in milden Wintern schon im Januar
blüht, die dieses Jahr also seit Wochen in der Westhälfte die Allergiker nervt.
Auch die Erlenpollen machen sich im Südwesten inzwischen bemerkbar.
Fürs Auge schön zeigen sich im Laufe des Monats Schneeglöckchen,
Krokusse und Winterlinge. Zumindest am Boden wird es also langsam
bunter.

Und was kann uns meteorologisch blühen? (more…)

The Death of the Death Penalty?

Texas leads the nation in executions. Minnesota has no death penalty. So two researchers—one from the University of Minnesota and one from the University of Texas at Austin (UT Austin)—teamed up to find out something no one had ever looked at before: what the death penalty does for the murder victims’ families. They compared family survivors’ experiences in Texas with Minnesota, the latter one of 18 states with life without the possibility of parole (LWOP) as its “Ultimate Penal Sanction.”

The study used in-person interviews with victims’ families to examine the death penalty process and its long-term impact on the families. (more…)

Erfolgreiche Renaturierung von Gewässern: Das biologische Umfeld ist entscheidend

Aufwändige Renaturierungsmaßnahmen sollen die biologische Vielfalt zurück in Bäche und Flüsse holen. Doch der Erfolg ist nicht garantiert. Woran liegt’s? Gewässerökologen der Senckenberg Gesellschaft für Naturforschung und des LOEWE Biodiversität und Klima Forschungszentrums (BiK-F) haben 18 Gewässerrenaturierungen untersucht. Sie konnten belegen, dass Fischarten meist dort wieder einwandern, wo schon das biologische Umfeld Vielfalt bietet. Wie das Artenspektrum in der Umgebung aussieht, gehört zu den wichtigsten Faktoren für erfolgreiche Wiederansiedlung und sollte daher schon bei der Planung von Renaturierungen berücksichtigt werden. Die Studie ist im Januar 2014 im Fachmagazin PlosOne erschienen.

Renaturierungen von Bächen und Flüssen lassen sich nicht allein am Reißbrett planen. Neben der Lebensraumvielfalt im Gewässer selbst und der Nutzung der Umgebung bestimmen eine ganze Reihe weiterer Faktoren, ob ein Lebensraum eine artenreiche Lebensgemeinschaft beherbergen kann und wird. Wissenschaftler der Senckenberg Gesellschaft für Naturforschung und des LOEWE Biodiversität und Klima Forschungszentrums (BiK-F) untersuchten 18 renaturierte Gewässerabschnitte im Hinblick auf die dort vorhandenen Fischpopulationen.

COLUMBUS, Ohio — Practicing yoga for as little as three months can reduce fatigue and lower inflammation in breast cancer survivors, according to new research.

The more the women in the study practiced yoga, the better their results. (more…)
