USC researchers detail process of beak formation in journal Science
The shapes of avian beaks are determined by areas of active growth amidst areas of slow growth in a developing embryo, and are associated with activity levels of a specific protein called bone morphogenetic protein 4 (BMP4), according to a group of researchers from the Keck School of Medicine of the University of Southern California. Their paper, which describes this molecular beak-shaping process, will be published in this week’s issue of the journal Science. A report on this paper and another closely related study will appear in the journal’s news section.
Different bird species tend to have differently shaped beaks, which are said to reflect the different evolutionary pressures under which they develop. In fact, Charles Darwin looked to 13 different species of finch from the Galapagos Islands to help bolster his theories of evolution, showing that while the Galapagos finches had most likely descended from a common ancestor, they had developed into distinct species based on differences in their beaks-differences which corresponded with their confinement to different islands in the archipelago and their adaptation to different ecological niches.

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...
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...
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.

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