Erstmals Sandmücke in Hessen entdeckt

Wissenschaftler des Senckenberg Forschungsinstituts, des LOEWE Biodiversität und Klima Forschungszentrums (BiK-F) und der Goethe-Universität in Frankfurt haben die erste in Hessen gefundene Sandmücken-Art identifiziert. Die Mücke ist ein potentieller Überträger der Krankheit Leishmaniose.  Der Fund ist der bisher nördlichste weltweit. Die zugehörige Studie ist kürzlich im Fachjournal „Parasitology Research“ erschienen.

Die beigefarbenen Sandmücken sind nur wenige Millimeter groß und lieben es eigentlich warm. Ihre Hauptverbreitungsgebiete sind die Tropen, Subtropen und der Mittelmeerraum – dort übertragen die winzigen Mücken nicht selten die Infektionskrankheit Leishmaniose. (more…)

Scientists Find Possible Solution to an Ancient Enigma

The widespread disappearance of stromatolites, the earliest visible manifestation of life on Earth, may have been driven by single-celled organisms called foraminifera.

The findings, by scientists at Woods Hole Oceanographic Institution (WHOI); Massachusetts Institute of Technology; the University of Connecticut; Harvard Medical School; and Beth Israel Deaconess Medical Center, Boston, were published online the week of May 27 in the Proceedings of the National Academy of Sciences.

Chagas Disease May Be A Threat in South Texas, Says Researcher

AUSTIN, Texas — Chagas disease, a tropical parasitic disease that can lead to life-threatening heart and digestive disorders, may be more widespread in Texas than previously thought, according to research from The University of Texas at Austin.

“We’ve been studying this for four years now, and this year the number of disease-causing insects is quite amazing,” says Sahotra Sarkar, professor of integrative biology and philosophy at The University of Texas at Austin and lead author of a paper on the disease published in PLoS Neglected Tropical Diseases.

Tiny Protozoa May Hold Key to World Water Safety

Right now, it looks a little like one of those plastic containers you might fill with gasoline when your car has run dry. But Scott Gallager is not headed to the nearest Mobil station. The Woods Hole Oceanographic Institution (WHOI) biologist has other, grander plans for his revolutionary Swimming Behavioral Spectrophotometer (SBS), which employs one-celled protozoa to detect toxins in water sources.

Not only is he working on streamlining the boxy-looking contraption—eventually even evolving it into a computer chip—but he sees it as a tool to potentially  “monitor all the drinking water in the world.

“It has a unique utility.” (more…)

The Natural World of the Human Mouth

According to scientists, the number of species of microorganisms that permanently reside in the human oral cavity amounts to 200-500. Of those, only fifty are named and studied. They have various looks: balloons, ovoids, bacilli, those that look like corn on the cob, bottle brushes, spirals, zippers, etc. What of the inhabitants of the mouth are our enemies, and what are friends?
