How does a wing grow? A journey on the path of proteins

How organs develop and how they grow to the right size and shape are fundamental questions in developmental biology. The morphogen Dpp is a signaling molecule controlling the development of different organs with regard to ...

Scientists discover new approach to stabilize cathode materials

A team of researchers led by chemists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory has studied an elusive property in cathode materials, called a valence gradient, to understand its effect on battery ...

Cells use concentration gradients as a compass

Biophysicists at Ludwig-Maximilians-Universitaet (LMU) in Munch have developed a new theory, which accounts for the observation that cells can perceive their own shapes, and use this information to direct the distribution ...

Elucidating the mechanism of a light-driven sodium pump

Researchers at the Paul Scherrer Institute PSI have succeeded for the first time in recording a light-driven sodium pump from bacterial cells in action. The findings promise progress in the development of new methods in neurobiology. ...

The superheroes of nutrient detection living in our oceans

By and large, marine bacteria have a fairly simple existence – eat, divide, repeat. But the first step isn't always straightforward. There are lots of nutrients in the ocean, but there's no Uber Eats for microscopic organisms. ...

Deciphering the mechanism that determines organ size and shape

A study by IRB Barcelona's Development and Growth Control Laboratory, headed by ICREA researcher Marco Milán, reveals how Dpp and Wg morphogens regulate organ proportions and patterning of the fly wing through independent ...

'Blue energy' seems feasible and offers considerable benefits

Generating energy on a large scale by mixing salt and fresh water is both technically possible and practical. The worldwide potential for this clean form of energy - 'blue energy' or 'blue electricity' - is enormous. However, ...
