Progress in super-resolution microscopy

Going deeper and deeper into cells with the microscope; imaging the nucleus and other structures more and more accurately; getting the most detailed views of cellular multi-protein complexes: All of these are goals pursued ...

Plant root hairs form outward due to shank hardening

A group of international researchers has discovered how plant root hair grows straight and long. Many studies of root hair growth have been performed, but the molecular mechanism for the suppression of growth on the sides ...

Researchers identify key pathway for plant cell growth

For plants, the only way to grow is for cells to expand. Unlike animals, cell division in plants happens only within a tiny region of the root and stem apex, making cell expansion the critical path to increased stature.

The future of plant science -- a technology perspective

Plant science is key to addressing the major challenges facing humanity in the 21st Century, according to Carnegie's David Ehrhardt and Wolf Frommer. In a Perspective published in The Plant Cell, the two researchers argue ...

Materials that shrink when heated

One common reason that people with fillings experience toothache is that their fillings expand at a different rate to the original tooth when, for example, drinking a hot drink. Contrary to intuition, however, not all materials ...
