Up to now it was thought that nutrients penetrated the interior of plant cells by means of substance-specific transporters. Nevertheless, researchers at the Agrobiotechnology Institute at the Public University of Navarra have shown that the nutrients (saccharose, amino-acids, etc.) penetrate the cells basically through an “endocitic”, mechanism similar to fagocitosis, and induced by saccharose. This finding, carried by the latest issue of the Japanese journal, Plant Cell Physiology, will enable the design of experiments aimed at enhancing vegetable species in the interest of humanity.
Researchers at the Institute have shown that, in the presence of saccharose (a substance produced in leaves to be subsequently distributed around the plant), the cells of the reserve organs - such as roots, tubers, seeds or fruits - “swallow up” nutrients in order to metabolise and store them. These “swallowed-up” substances are incorporated into micro-vesicles that end up pouring their contents into an internal compartment of a vegetable cell known as the vacuola. Once inside the vacuola, the substances or nutrients are broken up, stored and metabolised.

Dead and alive at the same time? Researchers at the Max Planck Institute of Quantum Optics have implemented Erwin Schrödinger’s paradoxical gedanken experiment employing an entangled atom-light state.
In 1935 Erwin Schrödinger formulated a thought experiment designed to capture the paradoxical nature of quantum physics. The crucial element of this gedanken...
Cellulose obtained from wood has amazing material properties. Empa researchers are now equipping the biodegradable material with additional functionalities to produce implants for cartilage diseases using 3D printing.
It all starts with an ear. Empa researcher Michael Hausmann removes the object shaped like a human ear from the 3D printer and explains:
The phenomenon of so-called superlubricity is known, but so far the explanation at the atomic level has been missing: for example, how does extremely low friction occur in bearings? Researchers from the Fraunhofer Institutes IWM and IWS jointly deciphered a universal mechanism of superlubricity for certain diamond-like carbon layers in combination with organic lubricants. Based on this knowledge, it is now possible to formulate design rules for supra lubricating layer-lubricant combinations. The results are presented in an article in Nature Communications, volume 10.
One of the most important prerequisites for sustainable and environmentally friendly mobility is minimizing friction. Research and industry have been dedicated...
