Hard to crack research reveals how crop roots penetrate hard soils

Scientists have discovered a signal that causes roots to stop growing in hard soils which can be 'switched off' to allow them to punch through compacted soil—a discovery that could help plants to grow in even the most damaged ...

Comb of a lifetime: A new method for fluorescence microscopy

Fluorescence microscopy is widely used in biochemistry and life sciences because it allows scientists to directly observe cells and certain compounds in and around them. Fluorescent molecules absorb light within a specific ...

Researchers develop new way to break reciprocity law

An international research team lead by Aalto University has found a new and simple route to break the reciprocity law in the electromagnetic world, by changing a material's property periodically in time. The breakthrough ...

Global study on bird song frequency

An analysis of the songs of most of the world's passerine birds reveals that the frequency at which birds sing mostly depends on body size, but is also influenced by sexual selection. The new study from researchers of the ...

Newly discovered receptor helps to sneak a peek at evolution

Together with lipids, membrane proteins are a central component of all biological membranes and fulfill important functions in transport and information transfer within and between cells. The majority of membrane proteins ...

Optoacoustic sensor measures water content in living tissue

Researchers from Skoltech and the University of Texas Medical Branch (US) have shown how optoacoustics can be used for monitoring skin water content, a technique which is promising for medical applications such as tissue ...
