Dust-sized wireless communications nodes, pinhead-size cameras, and other sensors; contact-lens video displays and wearable computers controlled by subvocal speech and other muscle movements; and the ability to google anything, anywhere--we will soon be able to know almost everything about everyone. Explosive advances in the technologies of sensing and data mining demand that we ask: is privacy a fundamental right or a passing phenomenon?
Privacy is mentioned in neither the U.S. Constitution nor John Stuart Mills seminal work, "On Liberty." Nor does it seem to have been a basic aspect of any civilization before the late Victorian era. Perhaps its nothing more than a single centurys luxury, supported by an odd combination of technologies: the urban apartment building and subways, the suburban home and private automobiles.
In a special four-part report in IEEE Spectrum, "Sensor Nation," we look at privacy under siege. Part one, "Sensors and Sensibility," reviews the latest developments in sensing and data mining, and at a rear-guard of technologists who are fighting back, developing technologies of privacy. A second article, "We Like to Watch," tackles head-on the difficult question of what a society without privacy would be like. Is there a healthy alternative, a so-called transparent society, in which the loss of privacy is symmetrical and universal, matched by a powerful new ability to watch the watchers?

At the Hannover Messe 2018, the Bundesanstalt für Materialforschung und-prüfung (BAM) will show how, in the future, astronauts could produce their own tools or spare parts in zero gravity using 3D printing. This will reduce, weight and transport costs for space missions. Visitors can experience the innovative additive manufacturing process live at the fair.
Powder-based additive manufacturing in zero gravity is the name of the project in which a component is produced by applying metallic powder layers and then...
Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.
Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...
University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...
Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.
The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
