Fitting a right hand in a left-handed mitten

Many biomolecules come in two versions that are each other's mirror image, like a left and a right hand. Cells generally use the left-hand version of amino acids to produce proteins, and uptake mechanisms were thought to ...

Blazes of light reveal how plants signal danger long distances

In one video, you can see a hungry caterpillar, first working around a leaf's edges, approaching the base of the leaf and, with one last bite, severing it from the rest of the plant. Within seconds, a blaze of fluorescent ...

A new model for communication in plant cells

Plant cells share a strange and surprising kinship with animal neurons: many plant cells have proteins that closely resemble glutamate receptors, which help to relay nerve signals from one neuron to another. While plants ...

Brain genes related to innovation revealed in birds

Wild birds that are more clever than others at foraging for food have different levels of a neurotransmitter receptor that has been linked with intelligence in humans, according to a study led by McGill University researchers. ...

Proteins keep a grip on cells

Japanese scientists at Osaka University have revealed new structural information on the integrin-laminin interaction. These findings provide important insights on cellular interactions that promote cell growth, differentiation, ...

Experiment shows non-classical growth of crystals

This might considerably speed up crystal growth that is of major importance in a number of materials and applications. The liquid state of the building blocks in the preliminary stage might also accelerate the effectiveness ...

Special delivery: Macromolecules via spider's 'bite'

Our cells are rich in proteins which are potential targets for therapy. But study of these proteins' behavior, using externally delivered biomacromolecules, has often been stymied by the difficulty of gaining access to the ...
