A group of just nine climate scientists is trying to change the media coverage of their discipline. Thanks to an ongoing revolution in electronic news, they might just succeed.
Resistance to insulin predisposes people to diabetes; it is characterized by increased storage of fats and a failure to stop glucose synthesis. The molecular underpinnings of these effects have been uncovered.
One of the great uncertainties in projecting global warming is accounting for the effects of small particles in Earth's atmosphere. Progress is nonetheless being made with this fiendishly complex problem.
An antenna array that is metres high and wide can detect and transmit radio waves. This effect has now been demonstrated at much smaller electromagnetic wavelengths in a nanoscale array of carbon nanotubes.
