Hormonal birth control alters scent communication in primates

Hormonal contraceptives change the ways captive ring-tailed lemurs relate to one another both socially and sexually, according to a Duke University study that combined analyses of hormones, genes, scent chemicals and behavior.

Small wires make big connections for microelectronics

University of Illinois engineers have developed a novel direct-writing method for manufacturing metal interconnects that could shrink integrated circuits and expand microelectronics.

Woven electronics

Electrical engineers from ETH Zurich have devised intelligent textiles that already have electronic components such as sensors and conductive filaments woven into them. The advantage: the fabric can be mass-produced on conventional ...

Japan mines toxic e-waste for precious materials

Seeking to turn an environmental problem into an economic opportunity, high-tech companies in resource-poor Japan are mining mountains of toxic e-waste for precious materials.

Measuring Electron Orbitals

(PhysOrg.com) -- For the first time, it has been possible to measure electron density in individual molecular states using what is known as the photoelectric effect. Now published in Science, this method represents a key ...

Hollow spheres made of metal

Producing metallic hollow spheres is complicated: It has not yet been possible to make the small sizes required for new high-tech applications. Now for the first time researchers have manufactured ground hollow spheres measuring ...

Nanotechnology gets a new light touch

(PhysOrg.com) -- Building the super-fast computers of the future has just become much easier thanks to an advance by Australian researchers that lets them grab hold of tiny electronics components and probe their inner structure ...
