Biologists at UC San Diego have succeeded in visualizing the movement within plants of a key hormone responsible for growth and resistance to drought. The achievement will allow researchers to conduct further studies to determine how the hormone helps plants respond to drought and other environmental stresses driven by the continuing increase in the atmosphere?s carbon dioxide, or CO2, concentration.

A common assumption is that once a nanocarrier is created, it maintains its size and shape on the shelf as well as in the body. However, recent work has shown that routine procedures in handling and processing nanocarrier solutions can have a significant influence on the size and shape of these miniscule structures.

Strain-induced polarization charges in piezoelectric semiconductors can effectively modulate the electronic and optoelectronic processes of charge carriers at the metal-semiconductor interface and p-n junction, which has resulted in both novel fundamental phenomenon and unprecedented device applications. The increasing research interests in the emerging field of piezotronics and piezo-phototronics has opened up opportunities for implementing novel applications such as adaptive human-electronics interfacing, active flexible/stretchable electronics, sensing, energy harvesting, biomedical treatments and optical MEMS.

The complexity of biology can befuddle even the most sophisticated light microscopes. Biological samples bend light in unpredictable ways, returning difficult-to-interpret information to the microscope and distorting the resulting image. New imaging technology rapidly corrects for these distortions and sharpens high-resolution images over large volumes of tissue.

Researchers have invented a new type of tiny, smartphone-readable particle that they believe could be deployed to help authenticate currency, electronic parts, and luxury goods, among other products. The particles, which are invisible to the naked eye, contain colored stripes of nanocrystals that glow brightly when lit up with near-infrared light.
