Nailing down a crucial plant signaling system

Plant biologists have discovered the last major element of the series of chemical signals that one class of plant hormones, called brassinosteroids, send from a protein on the surface of a plant cell to the cell's nucleus. ...

Nanoscale gene 'ignition switch' may help spot and treat cancer

(PhysOrg.com) -- In a proof of principal study in mice, scientists at Johns Hopkins and the Virginia Commonwealth University (VCU) have shown that a set of genetic instructions encased in a nanoparticle can be used as an ...

Respiratory virus infection triggers new class of biomolecules

(PhysOrg.com) -- For the first time, scientists have discovered that a poorly understood class of RNA produced in a mammal's cells during a respiratory virus attack may affect the outcome of the infection. Their findings ...

Histone H1 regulates gene activity throughout the cell cycle

A protein that helps pack DNA into the cell nucleus has an important role in regulating gene activity, scientists report. The researchers found that the protein, histone H1, also takes part in the formation of ribosomes, ...

Paper wasps and honey bees share a genetic toolkit

They are both nest-building social insects, but paper wasps and honey bees organize their colonies in very different ways. In a new study, researchers report that despite their differences, these insects rely on the same ...
