Individual atoms of a certain chemical element can be very stubborn when it comes to separation, mainly because techniques rely on a difference in chemical and physical properties – atoms are almost identical in both regards. However, if you peer closely enough into the atoms, there are subtle differences that can have very big effects. These "different" atoms, called isotopes, are heavily relied on in areas of medicine and nuclear energy and now researchers have proposed a novel way...

How long does it take an electron to form a photon? The answer would normally be: so short a time that it cannot be measured. However, the international CERN team responsible for experiment NA63 — mainly staffed by physicists from Aarhus University — has now succeeded in dragging out the process, thereby making it measurable. They achieved this by utilizing the phenomena of objects moving slower and shortening in length from Einstein´s theory of relativity, along with two...

One More Victory Scored Over Uncertainty In Quantum Physics Measurements

Squeezing what hasn't been squeezed before Most people attempt to reduce the little uncertainties of life by carrying umbrellas on cloudy days, purchasing automobile insurance or hiring inspectors to evaluate homes they might consider purchasing. For scientists, reducing uncertainty is a no less important goal, though in the weird realm of quantum physics, the term has a more specific meaning. For scientists working in quantum physics, the Heisenberg Uncertainty Principle says that...

AAAS presentation: Charles Clark Just as NASA engineers test new rocket designs in computer studies before committing themselves to full prototypes, so physicists will often model matter under various circumstances to see whether something new appears. This is especially true of atomtronics, a relatively new science devoted to creating artificial tailored materials consisting of neutral atoms held in an array with laser beams, or atoms moving along a desired track under electric or...

[ Watch the Video ] A team of Australian and American researchers announced on Sunday that they had created a working transistor from a single phosphorus atom embedded precisely in a silicon crystal. The transistor was completed by physicists at the University of New South Wales (UNSW), the University of Melbourne, and Purdue University, and according to a UNSW press release, this "remarkable feat of micro-engineering“¦ uses as its active component an individual phosphorus...

Safari User Sues Google Over Alleged Privacy Rights Violations
2012-02-19 05:25:34

A user of the Safari web browser is suing Google, accusing the largest online search engine on the planet of violating his privacy rights in Apple's iPhone and iPad line of products, Bloomberg reported on Friday. According to reporters Phil Milford and Jef Feeley, the lawsuit was filed by Illinois resident Matthew Soble and stems from earlier reports claiming that Google was one of a handful of companies utilizing a piece of clandestine code to get around security settings in the Internet...

WSJ: Google Used Illicit Code To Track iPhone Activity

According to a report by the Wall Street Journal, Google along with a handful of advertising companies has been using a piece of clandestine code to get around security settings in Apple´s Safari web browser in order to track iPhone users´ online activities. The investigation stated that Google and ad networks Vibrant Media, Media Innovation Group and Gannett PointRoll had circumvented Safari´s privacy settings by using code that falsely represents its advertisements as...

Researchers from the University of York are pioneering the development of electron microscopes which will allow scientists to examine a greater variety of materials in new revolutionary ways. The team, headed by Professor Jun Yuan and Professor Mohamed Babiker, from the University´s Department of Physics has created electron beams with orbital angular momentum — electron vortex beams — which will open the way to many novel applications including the more efficient...

For the first time, an experiment shows that atomic nuclei can become transparent At the high-brilliance synchrotron light source PETRA III, a team of DESY scientists headed by Dr. Ralf Röhlsberger has succeeded in making atomic nuclei transparent with the help of X-ray light. At the same time they have also discovered a new way to realize an optically controlled light switch that can be used to manipulate light with light, an important ingredient for efficient future quantum...
