Fecal matter of red colobus monkeys collected in western Uganda has yielded a wealth of knowledge about human land-use change and wildlife health and conservation. The main lesson, researchers say, is that the intensity of tree removal translates directly to parasite populations and the risk of infection of their hosts.
In an effort to glean predictive power out of years of research on the effects of forest fragmentation on various species and ecological processes, researchers looked at nine differently fragmented regions of forests located in what is now agricultural landscape just west of Kibale National Park, in the foothills of the Ruwenzori Mountains. Within these regions, they focused on populations of red colobus (Piliocolobus tephrosceles) monkeys and the presence of strongyle and rhabditoid nematodes.
For two years, Thomas R. Gillespie, a professor of pathobiology in the University of Illinois College of Veterinary Medicine, and Colin A. Chapman, an anthropologist at McGill University in Canada, surveyed the monkeys and determined nematode levels by examining 536 colobus fecal samples. Their study appears in the April issue of the journal Conservation Biology.

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
