A frog in the throat

Kiel scientist takes sensational image of a frog in a frog

"I work as a research associate on a project into the sticky characteristics of amphibian tongues", says Dr Thomas Kleinteich, from the Functional Morphology and Biomechanics working group at the Zoological Institute at Kiel University.

He generates three-dimensional computer models of animals using a micro-CT scanner, which works in a similar way to a medical CT scanner but is designed for investigating small objects. Kleinteich: "To do so, I use museum specimens conserved in alcohol. In this case, it is a South-American horned frog Ceratophrys from the collection at the Zoological Museum in Hamburg."

When analysing the scan, Kleinteich found that another animal was present inside the frog: "We have known for a while that horned frogs are able to eat very large prey.

Last year I was able to show experimentally, that horned frogs can produce extremely strong adhesive strength with their tongues, which they also need in order to catch larger prey. With the micro-CT I am able to show, for the first time, how such a large catch can even fit inside a horned frog."

The image of the frog with a frog in its throat won a competition in May from the CT-manufacturing company “Bruker microCT”.

Im Focus: UNH scientists help provide first-ever views of elusive energy explosion

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.

Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...

Im Focus: A Chip with Blood Vessels

Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.

Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...

Im Focus: A Leap Into Quantum Technology

Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.

In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...

Im Focus: Research icebreaker Polarstern begins the Antarctic season

What does it look like below the ice shelf of the calved massive iceberg A68?

On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.

Im Focus: Penn engineers develop ultrathin, ultralight 'nanocardboard'

When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure

Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
