New research indicates that the honey bee diet influences the bees’ ability to withstand at least some of these assaults. Some components of the nectar and pollen grains bees collect to manufacture fo...Life Sciences | Read more
A mechanism that permits essential substances to enter our cells while at the same time removing from them harmful components also has a “down side.” This negative aspect prevents vital drugs, such as...Studies and Analyses | Read more
In the spring following a forest fire, trees that survived the blaze explode in new growth and plants sprout in abundance from the scorched earth. For centuries, it was a mystery how seeds, some long ...Ecology, The Environment and Conservation | Read more
Plants are generally firmly rooted in the ground so that they cannot just move to a different place when the conditions become too dry or uncomfortable in any other way. Therefore, they must be alert ...Life Sciences | Read more
Now, working together, scientists from the Florida campus of The Scripps Research Institute (TSRI), Columbia University and the University of Florida, Gainesville, have developed a novel strategy for ...Life Sciences | Read more
For much of Asia, the pace of life is tuned to rhythms of monsoons. The summer rainy season is especially important for securing the water and food supplies for more than a billion people. Its...Earth Sciences | Read more
Ocean acidification, which occurs as CO2 is absorbed by the world's oceans, is known to negatively impact a wide variety of marine animals ranging from massive corals to microscopic plankton. How...Studies and Analyses | Read more

New indicator molecules visualise the activation of auto-aggressive T cells in the body as never before
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 ...
A fried breakfast food popular in Spain provided the inspiration for the development of doughnut-shaped droplets that may provide scientists with a new approach for studying fundamental issues in physics, mathematics and materials.
The doughnut-shaped droplets, a shape known as toroidal, are formed from two dissimilar liquids using a simple rotating stage and an injection needle. About a millimeter in overall size, the droplets are produced individually, their shapes maintained by a surrounding springy material made of polymers.
Droplets in this toroidal shape made ...
Frauhofer FEP will present a novel roll-to-roll manufacturing process for high-barriers and functional films for flexible displays at the SID DisplayWeek 2013 in Vancouver – the International showcase for the Display Industry.
Displays that are flexible and paper thin at the same time?! What might still seem like science fiction will be a major topic at the SID Display Week 2013 that currently takes place in Vancouver in Canada.
High manufacturing cost and a short lifetime are still a major obstacle on ...
University of Würzburg physicists have succeeded in creating a new type of laser.
Its operation principle is completely different from conventional devices, which opens up the possibility of a significantly reduced energy input requirement. The researchers report their work in the current issue of Nature.
It also emits light the waves of which are in phase with one another: the polariton laser, developed ...
Innsbruck physicists led by Rainer Blatt and Peter Zoller experimentally gained a deep insight into the nature of quantum mechanical phase transitions.
They are the first scientists that simulated the competition between two rival dynamical processes at a novel type of transition between two quantum mechanical orders. They have published the results of their work in the journal Nature Physics.
“When water boils, its molecules are released as vapor. We call this ...
