Mechanism of jasmonate-promoted root hair growth in Arabidopsis

Root hairs are tubular polarized extensions of root epidermal cells and are crucial for plant anchorage, nutrient acquisition, and environmental interactions. The plant hormone jasmonate has been reported to promote root ...

Tiny, erratic protein motor movements revealed

The smallest proteins travel in our cells, completing deeply important tasks to keep our molecular mechanisms moving. They are responsible for transporting cargo, duplicating cells and more. Now, a research team based in ...

Lane change in the cytoskeleton

Many amphibians and fish are able to change their color in order to better adapt to their environment. Munich-based scientists have now investigated the molecular mechanisms in the cytoskeleton necessary for this and revealed ...

How do corals make the most of their symbiotic algae?

Corals depend on their symbiotic relationships with the algae that they host. But how do they keep algal population growth in check? The answer to this fundamental question could help reefs survive in a changing climate.

'Super' simulations offer fresh insight into serotonin receptors

Scientists at the University of Maryland (UMD) and the National Institute of Standards and Technology (NIST) have discovered a way to detect the molecular mechanism by which 5HT3A, a serotonin receptor located at the neuron ...

Bacteria can 'outsmart' programmed cell death

Certain bacteria can override a defence mechanism of the immune system, so called programmed cell death, through inhibition of death effector molecules by their outer membranes components. Shigella bacteria, which cause diarrhoea, ...

Memory

In psychology, memory is an organism's mental ability to store, retain and recall information. Traditional studies of memory began in the fields of philosophy, including techniques of artificially enhancing the memory. The late nineteenth and early twentieth century put memory within the paradigms of cognitive psychology. In recent decades, it has become one of the principal pillars of a branch of science called cognitive neuroscience, an interdisciplinary link between cognitive psychology and neuroscience.
