3D-printer with nano-precision

Printing three dimensional objects with incredibly fine details is now possible using "two-photon lithography". With this technology, tiny structures on a nanometer scale can be fabricated. Researchers at the Vienna University of Technology (TU Vienna) have now made a major breakthrough in speeding up this printing technique: The high-precision-3D-printer at TU Vienna is orders of magnitude faster than similar devices (see video). This opens up completely new areas of application, such as in medicine.

Researchers send 'wireless' message using neutrinos

(PhysOrg.com) -- A group of scientists led by researchers from the University of Rochester and North Carolina State University have for the first time sent a message using a beam of neutrinos – nearly massless particles that travel at almost the speed of light. The message was sent through 240 meters of stone and said simply, "Neutrino."

A cheap and fully optical solution for ultra-fast Internet

Blisteringly fast Internet speeds, more robust connections and a big increase in network capacity at little extra cost, even in rural areas? It

Second biggest flare of the solar cycle

The leading edge of the first of two major coronal mass ejections will reach Earth at about 1:25 AM EST on the morning of March 8 (plus or minus 7 hours). Such a CME could result in a severe geomagnetic storm, causing aurora at low latitudes, with possible disruption to high frequency radio communication, global positioning systems (GPS), and power grids.

First results from Daya Bay find new kind of neutrino transformation

The Daya Bay Reactor Neutrino Experiment, a multinational collaboration operating in the south of China, today reported the first results of its search for the last, most elusive piece of a long-standing puzzle: how is it that neutrinos can appear to vanish as they travel? The surprising answer opens a gateway to a new understanding of fundamental physics and may eventually solve the riddle of why there is far more ordinary matter than antimatter in the universe today.

'Holey Optochip' first to transfer one trillion bits of information per second using the power of light

(PhysOrg.com) -- IBM scientists today will report on a prototype optical chipset, dubbed “Holey Optochip”, that is the first parallel optical transceiver to transfer one trillion bits – one terabit – of information per second, the equivalent of downloading 500 high definition movies. The report will be presented at the Optical Fiber Communication Conference taking place in Los Angeles.

'Anti-atomic fingerprint': Physicists manipulate anti-hydrogen atoms for the first time (Update)

The ALPHA collaboration at CERN in Geneva has scored another coup on the antimatter front by performing the first-ever spectroscopic measurements of the internal state of the antihydrogen atom. Their results are reported in a forthcoming issue of Nature and are now online.

In the new book Space Chronicles: Facing the Ultimate Frontier, Neil deGrasse Tyson says America is at a critical moment for future space exploration, as he

World's best measurement of W Boson mass points to Higgs mass and tests standard model

The latest measurement of the mass of the W boson from the Tevatron experiments. The new combined result is twice as precise as the previous world average, and places limits on the mass of the Higgs consistent with the limits from direct searches at the LHC and Tevatron.

Developing sustainable power

Scientists suggest that renewable energy is a viable option for electrical power in developing and emerging nations. Researchers point out that in most of these nations, the demand for energy far exceeds the generating capacity.

World's smallest radio stations: two molecules communicate via single photons

We know since the dawn of modern physics that although events in our everyday life can be described by classical physics, the interaction of light and matter is down deep governed by the laws of quantum mechanics. Despite this century-old wisdom, accessing truly quantum mechanical situations remains nontrivial, fascinating and noteworthy even in the laboratory. Recently, interest in this area has been boosted beyond academic curiosity because of the potential for more efficient and novel forms of information processing.

Record-speed wireless data bridge demonstrated: takes high-speed communications the 'last mile'

Scientists have created a new way to overcome many of the issues associated with bringing high-speed digital communications across challenging terrain and into remote areas, commonly referred to as the "last mile" problem. The researchers developed a record-speed wireless data bridge that transmits digital information much faster than today
