Atomic-scale investigations solve key puzzle of LED efficiency

From the high-resolution glow of flat screen televisions to light bulbs that last for years, light-emitting diodes (LEDs) continue to transform technology. The celebrated efficiency and versatility of LEDs -- and other solid-state technologies including laser diodes and solar photovoltaics -- make them increasingly popular. Their full potential, however, remains untapped, in part because the semiconductor alloys that make these devices work continue to puzzle scientists. Scientists have now used electron microscopy imaging techniques to settle a solid-state controversy and raise new experimental possibilities.

New target to boost plant resistance to insects and pathogens identified

Plants have evolved unique and sophisticated immune systems to defend themselves against insects and pathogens. Plant hormones called jasmonates play an important role in this defense, but jasmonates have been found to also be important for plant growth. Now, researchers have discovered a gene in the jasmonate pathway that controls plant defenses but does not play a detectable role in plant development. These findings could be applied to improve crop resistance in agriculture.

Serengeti road divides biologists: Will a road across the northern tier of Serengeti National Park ruin it?

Serengeti National Park in Tanzania may be the most iconic national park in the world. Here, lions, leopards, elephants, hippos and giraffes wander free. Rivers of wildebeests, zebra and Thompson's gazelles -- more than 2 million all told -- cross the landscape in one of the largest animal migrations on the planet. While the park is ideally located for wandering wildebeests, its location is less than ideal for the region's residents. They see the undeveloped park as a formidable barrier to trade and travel. To address this, the Tanzania government now plans to build a gravel road across 50 km of the northern part of the park to link the country's coast to Lake Victoria and countries to the west, including Uganda, Rwanda and the Democratic Republic of the Congo.

Immune cell activation in multiple sclerosis: New indicator molecules visualize activation of auto-aggressive T cells

Biological processes are generally based on events at the molecular and cellular level. To understand what happens in the course of infections, diseases or normal bodily functions, scientists would need to examine individual cells and their activity directly in the tissue. The development of new microscopes and fluorescent dyes in recent years has brought this scientific dream tantalizingly close. Scientists from the Max Planck Institute of Neurobiology in Martinsried have now presented two studies introducing new indicator molecules which can visualize the activation of T cells. Their findings provide new insight into the role of these cells in the autoimmune disease multiple sclerosis (MS). The new indicators are set to be an important tool in the study of other immune reactions as well.
