Threatened by habitat loss, poaching, pollution and other factors, wildlife species across the globe are declining in number at an alarming rate. Scientists from the Bronx Zoo-based Wildlife Conservation Society (WCS) in New York City have been monitoring endangered wildlife populations for more than 100 years. For decades, traditional capture and tag methods have been a primary tool, but they are not the most efficient when dealing with large animals and animals in remote locations. The WCS’s recent use of satellite technology, sponsored by NASA, may revolutionize the way endangered wildlife in remote areas of the world are counted and monitored.
Comparing Ground and Satellite Images: Wildlife Conservation Society (WCS) scientists at the Bronx Zoo in New York City recently compared high resolution photographs taken from 450 kilometers (280 miles) overhead by cameras on the Quickbird satellite (the image to the right) with ground-based images of their animals taken simultaneously. The ground-based photo (the image to the left) shows a horse paddock with three horses. The numbered items, including number one, the grassy clearing, number two, a tree, and number three, a fence, can all be seen in the satellite image. WCS scientists are hopeful that they will be able to use this technology to monitor endangered animals in remote locations. Click on images to enlarge. Credit: Wildlife Conservation Society
Using cameras fixed to an orbiting satellite 450 kilometers (280 miles) overhead, WCS scientists say that they will be able to take high resolution photographs of specific areas to determine the wildlife composition within that area. They will then compare images from different dates to see changes, either population growth or decline, over time. The satellite, called Quickbird, is owned by DigitalGlobe, a private company.
To test their proposed use of satellite images, WCS scientists recently counted their own animal populations. High-tech maps produced by Quickbird, which orbited the Bronx Zoo in November 2004, have revealed incredibly clear images of everything from giraffes to Thomson’s gazelles. According to members of the team, the detail of the images taken from so far away has been particularly impressive. "We’re counting individual gazelles in the zoo’s African Plains exhibit from a satellite 280 miles up," said Dr. Scott Bergen. "That’s like standing on top of the Empire State Building and spotting a deer in Maine."

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...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
