Tracking parasites with satellites


Scientists are teaming up to use satellite data to target deadly parasites to help predict patterns of parasitic diseases such as malaria, worms and hydatids.

Project leader Professor Archie Clements, from The Australian National University, said the research could help authorities in developing countries fight parasitic diseases.

"Some diseases are highly sensitive to their environment, especially parasitic diseases. With remote sensing you can identify places where disease flourishes," said Professor Clements, Director of the ANU Research School of Population Health.

"This information is useful for decision makers to help them ensure scarce resources are targeted to where they are most needed."

Parasitic diseases affect hundreds of millions of people every year, many of them in the least developed parts of the world.

The team uses satellite data such as temperature, rainfall, vegetation and land usage, and combines it with health data in a geographical information system (GIS).

The approach combines the skills of many scientists, such as entomologists, epidemiologists, software developers, social scientists and health policy specialists.

"The result is maps that are accessible to countries with limited capacity for managing disease data, tailored to their local needs."

The team has trialed systems for malaria in Bhutan, Vanuatu and the Solomon Islands and is now seeking support to scale up to larger countries. Additionally, spatial predictions for other diseases such as worms and hydatids are being developed for China, the Philippines and other countries in the Asia-Pacific region.

"By taking this research the next step, we have the opportunity to have a meaningful impact on the real world, and save a lot of lives," Professor Clements said.

Professor Clements is laying out a plan for the future of these systems at a symposium at the American Association for the Advancement of Science Conference, in San Jose, California this weekend.

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

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...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

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.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

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...

Im Focus: New Products - Highlights of COMPAMED 2016

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...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'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...
