Human devices, from light bulbs to iPods, send information using electrons. Human bodies and all other living things, on the other hand, send signals and perform work using ions or protons.

A radical new way of making structures visible at the nano level has been developed at Johannes Gutenberg University Mainz (JGU, Germany).

Metrologists are measurement artists who are very precise – in the case of the Boltzmann constant up to the sixth decimal place. Whoever is able to determine it very exactly will cause a small revolution in the field of worldwide temperature measurement: The temperature unit will then no longer be based - as hitherto - on a chemico-physical material property, i.e. the triple point of water, but on an unchangeable fundamental constant.

(PhysOrg.com) -- Because they occur so infrequently, more often than not in areas where they aren’t recorded very well, scientists have been working nearly blind in trying to understand how tsunamis work once they reach shore. Now, Frederic Dias from University College in Dublin and his team of mathematical and computer scientists have developed a computer simulation that they believe explains how tsunamis work once they reach shore. They have described their findings in Physical Review Letters.

Scientists looking to capture evidence of dark matter -- the invisible substance thought to constitute much of the universe -- may find a helpful tool in the recent work of researchers from Princeton University and New York University.

The brightest gamma ray beam ever created- more than a thousand billion times more brilliant than the sun- has been produced in research led at the University of Strathclyde- and could open up new possibilities for medicine.

An international team of researchers led by the CNST has developed a new type of nanophotonic cavity that improves the efficiency of photon collection from individual quantum dots while enhancing the photon emission rate.

New research from NPL's Quantum Detection Group presents the most precise measurements of the quantum Hall effect ever made, using the two-dimensional material graphene.

Israel has become an associate member of the European Centre for Nuclear Research (CERN), opening the way for full membership in 2013, a foreign ministry spokesman said on Sunday.

A research team at Michigan State University has developed a laser that could detect roadside bombs – the deadliest enemy weapon encountered in Iraq and Afghanistan.

Fujitsu Laboratories announced the development of a compact silicon photonics light source for use in optical transceivers required for optical interconnects capable of carrying large volumes of data at high speeds between CPUs. In the past, when the silicon photonics light sources built into optical transceivers, and the optical modulators that encode data into the light emitted from the light source experienced thermal fluctuations, a mismatch between the lasing wavelength of the light source and the operating wavelength of the modulator could arise, causing concern that the light would not carry information. This is why thermal control has become indispensable as a way to maintain operating wavelengths that consistently match.

(PhysOrg.com) -- Ferromagnetic materials are key ingredients in vast arrays of technologies including wind turbines, computer hard-disks, credit card readers, and many more. Typically these magnets operate in moderate environments. But exposing a magnetic material to high heat or compressive stress usually destroys its magnetism because high temperatures and high compression induce agitation and mobility of unpaired electrons ("atomic compass"), destroying the correlated arrangement of atomic compasses across the solid needed to generate, or detect, magnetic fields

Just as a camera flash illuminates unseen objects hidden in darkness, a sequence of laser pulses can be used to study the elusive quantum behavior of a large "macroscopic" object. This method provides a novel tool of unprecedented performance for current experiments that push the boundaries of the quantum world to larger and larger scales.

Working together with other UH Manoa colleagues on the Belle experiment at the KEKB factory in Tsukuba, Japan, postdoctoral researcher Himansu Sahoo first reported the first observation of a new type of rare "penguin decay" of the beauty quark and measured its matter-antimatter symmetry violation parameters.

(PhysOrg.com) -- "Quantum computing could provide a way to significantly speed up the way we process certain algorithms," Malcolm Carroll tells PhysOrg.com. "The primary issue, though, is that you need a well controlled two-level system." He also points out that problems exist in terms of noise in quantum computing.
