US fertility experts today (Thursday 9 December) warned teenage boys and young men to consider limiting the time that they use laptop computers positioned on their laps, as long-term use may affect their fertility.
The increasing popularity of laptop computers (LC), coupled with existing evidence that elevated scrotal temperature can result in sperm damage, prompted researchers from the State University of New York at Stony Brook to undertake the first study into the effect of heat from LC on scrotal temperature.
The findings are reported in Europes leading reproductive medicine journal Human Reproduction. They show that using an LC on the lap increased the left scrotal temperature by a median 2.6°C and the right by a median 2.8°C. Several previous studies have shown that increases in testicular or scrotal temperatures of between 1°C and 2.9°C are associated with a sustained and considerable negative effect on spermatogenesis and fertility.

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...
