What makes plant cell walls both strong and extensible?

A plant cell wall's unique ability to expand without weakening or breaking—a quality required for plant growth—is due to the movement of its cellulose skeleton, according to new research that models the cell wall. The ...

How a plant regulates its growth

Plants grow towards the light. This phenomenon, which already fascinated Charles Darwin, has been observed by everyone who owns houseplants. Thus, the plant ensures that it can make the best use of light to photosynthesize ...

The force to shape an organ

Carnegie Mellon University professor of biomedical engineering and materials science and engineering Adam Feinberg, along with postdoctoral fellow Dan Shiwarski and graduate student Joshua Tashman, have created a novel biosensor ...

The balancing act between plant growth and defense

Researchers from Kumamoto University in Japan have pinpointed the mechanism that regulates the balance between plant growth and defense. Plants synthesize and accumulate protective hormones to protect them from pathogen infections, ...

Researchers discover skyrmions can split like biological cells

Scientists at the U.S. Department of Energy's Ames Laboratory have discovered that skyrmions— a type of quasiparticle with properties that could lead to the next generation of data storage and transfer— reproduce by splitting ...

Gold for iron nanocubes

One of the major challenges in nanotechnology is the precise control of shape, size and elemental composition of every single nanoparticle. Physical methods are able to produce homogeneous nanoparticles free of surface contamination. ...
