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.

In living cells, enzymes drive biochemical metabolic processes enabling reactions to take place efficiently. It is this very ability which allows them to be used as catalysts in biotechnology, for example to create chemical products such as pharmaceutics. Researchers now identified an enzyme that, when illuminated with blue light, becomes catalytically active and initiates a reaction that was previously unknown in enzymatics. The study was published in "Nature Communications".
Enzymes: they are the central drivers for biochemical metabolic processes in every living cell, enabling reactions to take place efficiently. It is this very...
Early detection of tumors is extremely important in treating cancer. A new technique developed by researchers at the University of California, Davis offers a significant advance in using magnetic resonance imaging to pick out even very small tumors from normal tissue. The work is published May 25 in the journal Nature Nanotechnology.

Microelectronics as a key technology enables numerous innovations in the field of intelligent medical technology. The Fraunhofer Institute for Biomedical Engineering IBMT coordinates the BMBF cooperative project "I-call" realizing the first electronic system for ultrasound-based, safe and interference-resistant data transmission between implants in the human body.
When microelectronic systems are used for medical applications, they have to meet high requirements in terms of biocompatibility, reliability, energy...
Thomas Heine, Professor of Theoretical Chemistry at TU Dresden, together with his team, first predicted a topological 2D polymer in 2019. Only one year later, an international team led by Italian researchers was able to synthesize these materials and experimentally prove their topological properties. For the renowned journal Nature Materials, this was the occasion to invite Thomas Heine to a News and Views article, which was published this week. Under the title "Making 2D Topological Polymers a reality" Prof. Heine describes how his theory became a reality.
Ultrathin materials are extremely interesting as building blocks for next generation nano electronic devices, as it is much easier to make circuits and other...
Scientists took a leukocyte as the blueprint and developed a microrobot that has the size, shape and moving capabilities of a white blood cell. Simulating a blood vessel in a laboratory setting, they succeeded in magnetically navigating the ball-shaped microroller through this dynamic and dense environment. The drug-delivery vehicle withstood the simulated blood flow, pushing the developments in targeted drug delivery a step further: inside the body, there is no better access route to all tissues and organs than the circulatory system. A robot that could actually travel through this finely woven web would revolutionize the minimally-invasive treatment of illnesses.
A team of scientists from the Max Planck Institute for Intelligent Systems (MPI-IS) in Stuttgart invented a tiny microrobot that resembles a white blood cell...
