Zebrafish help decode link between calcium deficiency and colon cancer
ANN ARBOR — A tiny, transparent fish embryo and a string of surprises led scientists to a deeper understanding of the perplexing link between low calcium and colon cancer.
By studying zebrafish embryo skin, University of Michigan researchers decoded cell messages underlying abnormal colonic cell growth of the kind that can lead to tumors and colon cancer in calcium deficient individuals. They have also tested this new mechanism in human colon cancer cells. (more…)
Pilot program study finds that pediatric obesity patients like telehealth services
For youth dealing with obesity who need extra help losing weight, experts suggest a multidisciplinary approach in which care is provided by several health specialists. However, the logistics of traveling to multiple appointments, even if just across town, can be a barrier to receiving care, especially for low-income families.
UCLA researchers who work with this patient population set up a pilot program using telehealth technology — a secure system that allowed patients to see and speak with their health care providers at UCLA over a computer from their local health clinic — to evaluate if such a system could be an effective strategy to help overcome these issues.

Drei tote Wölfe in einer Woche
NABU fordert Kompetenzstelle für den Wolfs-Schutz
In Deutschland sind innerhalb nur einer Woche drei Wölfe zu Tode gekommen. Nachdem am vergangenen Freitag ein Wolf illegal in der sächsischen Lausitz geschossen wurde, starben zwei weitere Anfang dieser Woche durch Verkehrsunfälle: Bereits am Montag wurde ein Wolf auf einer Bundesstraße im nördlichen Sachsen-Anhalt überfahren, einen weiteren erwischte auf dem Berliner Ring in Brandenburg. Menschen kamen dabei nicht zu Schaden. Zuletzt war am 16. November ein Wolf bei einem Verkehrsunfall getötet worden – fast an identischer Stelle wie das Tier in Sachsen-Anhalt am Montag. (more…)
Bats: Virtually a model of flight
“Virtual Reality Design for Science” is a co-listed class at Brown and RISD that unites artists, designers, computer scientists, and experts in scientific visualization. The goal: to create tools for immersive interaction with scientific data. Test case for the course: the flight mechanics of bats.
PROVIDENCE, R.I. [Brown University] — If you want to get a good look at a bat, a cave is a pretty good place to go. But on a Thursday in mid-December at Brown’s Granoff Center, there were virtual bats flapping about in a cave of a different sort. (more…)
Fatty Acids Crucial to Embryonic Development
Baltimore, MD— One classical question in developmental biology is how different tissue types arise in the correct position of the developing embryo. While one signaling pathway that controls this process has been well described, unexpected findings from a team led by Carnegie’s Steven Farber reveal the importance of polyunsaturated fatty acid metabolism in this process. It is published online December 12 in Developmental Cell.
Fatty acids serve as sources of energy, the building materials of cellular membranes, and as signals for sending messages between cells. Enzymes are needed to activate free fatty acids so that they are useful for cellular processes. The enzymes that perform this function are called acyl-CoA synthetases, often shortened to ACS. (more…)
Study Offers Economical Solutions for Maintaining Critical Delta Environments
Millions of people across the world live or depend on deltas for their livelihoods.
Formed at the lowest part of a river where its water flow slows and spreads into the sea, deltas are sediment-rich, biodiverse areas, a valuable source of seafood, fertile ground for agriculture, and host to ports important for transportation.
At least half of the deltas around the world are so-called “wave dominated deltas” – open to the sea and under the impact of wave erosion. And many more deltas will come under wave dominance as dammed rivers carry less and less sediment. In a warming climate, sea levels are rising and storms are increasing in frequency and severity, posing threats to these deltas and the people and habitats dependent on them. (more…)
E-Book zum Thema Detlef D! Soost Diät
Die Ernährung in der Detlef D! Soost Diät Mehr dazu im Ratgeber Detlef D! Soost Diät auf https://www.trendfit.net. Wer kennt das nicht? Wir haben versucht mit der Kohlsuppendiät abzunehmen, haben wochenlang nur Eier gegessen oder ganz auf etwas verzichtet – und nichts funktioniert.
Abnehmen klingt so leicht und ist in der Realität für viele doch ein lebensbeherrschendes Thema. Der aus dem Fernsehen bekannte Choreograph Detlef D Soost hat nun ein Diätprogramm gestartet, welches auf Bewegung, Ernährung und Motivation setzt. Wie speziell die Ernährung bei der “10 Weeks Body Change” – Diät (kurz: 10wbc) aussieht, finden sie hier. (more…)
