Scientists identify essential factors for limb formation

Scientists at the Centro Nacional de Investigaciones Cardiovasculares (CNIC), working in partnership with researchers at the Institut de Recherches Cliniques de Montréal (IRCM) in Canada, have identified Meis transcription ...

Researchers reveal the inner workings of a viral DNA-packaging motor

A group of researchers have discovered the detailed inner workings of the molecular motor that packages genetic material into double-stranded DNA viruses. The advance provides insight into a critical step in the reproduction ...

Which way does the solar wind blow?

The surface of the sun churns with energy and frequently ejects masses of highly-magnetized plasma towards Earth. Sometimes these ejections are strong enough to crash through the magnetosphere—the natural magnetic shield ...

Unique microscope to film molecules in motion

A unique electron microscope, set to break new ground in biological imaging, is being installed today at the Rosalind Franklin Institute in the UK. The machine is able to image biological samples at up to a million frames ...

Polar vortex, winter heat may change bird populations

For birds and other wildlife, winter is a time of resource scarcity. Extreme winter weather events such as a polar vortex can push some species to the edge of survival. Yet winter tends to get short shrift in climate change ...

How quantum dots can 'talk' to each other

So-called quantum dots are a new class of materials with many applications. Quantum dots are realized by tiny semiconductor crystals with dimensions in the nanometre range. The optical and electrical properties can be controlled ...

InSight Mars lander gets a power boost

The team behind NASA's InSight Mars lander has come up with an innovative way to boost the spacecraft's energy at a time when its power levels have been falling. The lander's robotic arm trickled sand near one solar panel, ...

Five million years of climate change preserved in one place

An international team of researchers, led by the Max Planck Institute for Chemistry in Mainz, Germany, has now succeeded in reconstructing changes in rainfall in Central Asia over the past five million years. The information ...
