Tiny nanomachine successfully completes test drive

Together with colleagues from the USA, scientists from the University of Bonn and the research institute Caesar in Bonn have used nanostructures to construct a tiny machine that constitutes a rotatory motor and can move in ...

Ultrashort laser pulses make greenhouse gas reactive

It is a long-cherished dream: Removing the inert greenhouse gas carbon dioxide from the atmosphere and using it as a basic material for the chemical industry. This could address two major problems at once by containing climate ...

Australian fire beetle avoids the heat

The Australian jewel beetle Merimna atrata has several heat sensors. Originally, it was thought to use them to detect forest fires as it lays its eggs in the wood of burned eucalyptus trees. Researchers at the University ...

An enzyme with a surprising dual function

Scientists at the University of Bonn have clarified a surprising dual function of ceramide synthase. The enzyme not only catalyzes a central step of the production of vital lipids, it also has the ability to turn genes involved ...

More genes are active in high-performance maize

When two maize inbred lines are crossed with each other, an interesting effect occurs: The hybrid offspring have a significantly higher yield than either of the two parent plants. Scientists at the University of Bonn have ...

Is the cosmic colossus RCS2J2327 heavier than allowed?

An international team of scientists led by researchers from the Argelander Institute for Astronomy has mapped the mass distribution in a distant galaxy cluster (RCS2J2327). This cosmic colossus is located in the constellation ...

Researchers show high-performance breathing in bones

Dinosaurs are far from extinct, but dominate as birds still most regions of the globe. Part of this huge success is due to the evolution of air sacs, which are crucial for the high efficiency of their respiratory system. ...

Plant defense following the iron-maiden principle

Calcium phosphate is a typical component of teeth and bones. It has recently been shown that plants of the rock nettle family also use this very hard mineral in their "teeth" to defend themselves against their animal enemies. ...

The oldest plesiosaur was a strong swimmer

Plesiosaurs were especially effective swimmers. These long extinct "paddle saurians" propelled themselves through the oceans by employing "underwater flight"—similar to sea turtles and penguins. Paleontologist from the ...
