Networks of gene activity control organ development

For the first time, researchers have decoded the genetic programmes that control the development of major organs in humans and other selected mammals—rhesus monkeys, mice, rats, rabbits and opossums—before and after birth. ...

Galaxies as 'cosmic cauldrons'

Star formation within interstellar clouds of gas and dust, so-called molecular clouds, proceeds very rapidly yet highly inefficiently. Most of the gas is dispersed by stellar radiation, revealing galaxies to be highly dynamic ...

New measurement device: Carbon dioxide as geothermometer

For the first time, it is now possible to measure, simultaneously and with extreme precision, four rare molecular variants of carbon dioxide (CO2) using a novel laser instrument. It is thus able to measure the temperature ...

Digital quantum simulators can be astonishingly robust

In solving quantum-physical problems in many-body systems, such as predicting material properties, conventional computers rapidly reach the limits of their capacity. Digital quantum simulators might help, but until now they ...

Are brown dwarfs failed stars or super-planets?

Brown dwarfs fill the "gap" between stars and the much smaller planets—two very different types of astronomical objects. But how they originate has yet to be fully explained. Astronomers from Heidelberg University may now ...

How proteins are assigned to specific transporters

A fundamental cellular mechanism ensures that proteins are transported to the places they are needed in the cells. So-called vesicles are responsible for that transport. Determining their composition has been difficult up ...

A volcanic binge and its frosty hangover

A major volcanic event could have triggered one of the largest glaciations in Earth's history—the Gaskiers glaciation, which turned the Earth into a giant snowball approximately 580 million years ago. Researchers from Heidelberg ...
