Turning the switch on biofuels

Plant cell walls contain a renewable, nearly limitless supply of sugar that can be used in the production of chemicals and biofuels. However, retrieving these sugars isn't all that easy.

Virus genes help determine if pea aphids get their wings

Many of an organism's traits are influenced by cues from the organism's environment. These features are known as phenotypically plastic traits and are important in allowing an organism to cope with unpredictable environments.

Researchers create most complete model of complex protein machinery

Environmental conditions, lifestyle choices, chemical exposure, and foodborne and airborne pathogens are among the external factors that can cause disease. In contrast, internal genetic factors can be responsible for the ...

Plant discovery opens frontiers

University of Adelaide researchers have discovered a biochemical mechanism fundamental to plant life that could have far-reaching implications for the multibillion dollar biomedical, pharmaceutical, chemical and biotechnology ...

Egg yolk precursor protein regulates mosquitoes' attraction to humans

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.
