House maintenance is a never-ending and costly task. Roofing, siding, windows and even garage doors wear out.
Now researchers at the National Institute of Standards and Technology (NIST) have developed a software program that takes the guesswork out of replacement decisions. The free program, called NEST (for National Economic Service-life Tools), allows homeowners to select the most cost-effective replacement material for roofing, siding, windows and garage doors. It also provides, for the users own zip code, cost estimates for replacements, including the cost of local labor and local materials, as well as the cost of maintenance.
NEST currently consists of two software tools. "NEST Builder" and "Durability Doctor." NEST Builder asks homeowners to specify the house layout and size, as well as various kinds of materials used for roofing, siding, windows and garage doors. The software program uses the information to build a virtual or graphic model of a users home.

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...
Terahertz excitation of selected crystal vibrations leads to an effective magnetic field that drives coherent spin motion
Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how...
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...
