Caterpillar study shows order in the complexity of tropical biodiversity
One of the worlds largest and highest-quality set of observations on live tropical insects and their host plants has led researchers to reinterpret the structure of tropical insect communities. The team of scientists who collaborated on this analysis includes Scott Miller of the Smithsonians National Museum of Natural History, Yves Basset of the Smithsonian Tropical Research Institute, Vojtech Novotny of the Czech Academy of Sciences and George Weiblen of the University of Minnesota. The findings from research in Papua New Guinea will be in the Nov. 22 edition of the Proceedings of the Royal Society of London. The research paper is available on the Web at www.pubs.royalsoc.ac.uk
Due to the present high interest in tropical biodiversity, there have been numerous studies on the subject in the last 20 years. These studies reported little predictability in the structure and composition of tropical insect communities, and they were based on techniques that sample dead insects with little data on their biology. "Predictably Simple: Assemblages of Caterpillars (Lepidoptera) Feeding On Rainforest Trees in Papua New Guinea" is a study that shows a different approach. The study was conducted using 35,942 live caterpillars, each carefully handpicked from the foliage in a lowland rainforest in Papua New Guinea. These caterpillars were then reared to adults, which allowed solid identification of species.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
