Your breakfast this morning came at a cost not only to your wallet. Your bowl of Cheerios and cup of coffee and all the other meals for the other 6 billion people in our world cost the Earth a bit of its water, a bit of its ecological diversity, contributed to its pollution and may one day cost us our livelihood.
In the July 22, 2005 issue of the journal Science, co-author Terry Chapin, professor of ecology at the University of Alaska Fairbanks (UAF) Institute of Arctic Biology (IAB), and colleagues point out that modern land-use practices may be trading short-term increases in food production for long-term losses in the environment’s ability to support human societies. Part of the solution, according to Chapin, is the students in UAF’s Regional Resilience and Adaptation Program (RAP).
Local land-use practices such as clearing tropical and boreal forests, practicing large-scale agriculture, expanding urban centers and intensifying farmland production are so pervasive their effects are now observed globally. Fertilizer use, which has increased 700% in the past 40 years, and human-caused atmospheric pollution now negatively affect water quality and coastal and freshwater ecosystems. Biodiversity is lost due to modification, fragmentation and loss of habitats, soil, and water, and exploitation of native species. Land-use practices play a role in changing the global carbon cycle, and possibly, the global climate.

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