Scientists find that black carbon is a good tracer to separate cooking organic aerosol from traffic-related organic aerosol.

Researchers from EPFL and the University Medical Center Utrecht in the Netherlands have developed an extremely fast optical method for sculpting complex shapes in stem-cell-laden hydrogels and then vascularizing the resulting tissue. Their groundbreaking technique stands to change the field of tissue engineering.

Now, researchers have shown that it is possible to evoke a shift in the metabolism from fermentation to respiration of E. coli and baker's yeast by optimizing fermentation conditions. This shift means that the cells can be pushed into producing more internal energy (ATP).

Japanese scientists at Tokyo University of Agriculture and Technology (TUAT) have found that for stroke patients, observing their own hand movements in a video-assisted therapy -- as opposed to someone else's hand -- could enhance brain activity and speed up rehabilitation.

For the first time, an HZB team has derived analytically how corkscrew-shaped nano-antennas interact with light. The mathematical tool can be used to calculate the geometry that a nano-antenna must have for specific applications in sensor technology or information technology.

A sophisticated chip the size of a coin in which cartilage can be cultivated and which can later be subjected to mechanical stress such that it generates the effects of Osteoarthrosis (OA).

Certain semiconductor structures, so-called quantum dots, might constitute the foundation of quantum communication. They are an efficient interface between matter and light, with photons (light particles) emitted by the quantum dots transporting information across large distances. However, structures form by default during the manufacture of quantum dots that interfere with communication.
