|X-ray phase tomography is an imaging technique that uses penetrating X-rays to create volumetric views through 'slices' of soft biological tissues, and it offers strongly enhanced contrast compared to conventional CT scans, yet scientists do not know which X-ray phase tomography methods are best suited to yield optimized results for a variety of conditions. To answer this question, a large group of researchers in Europe set out to compare three different X-ray phase tomography methods. ...> Full Article|
|Action-packed science-fiction movies often feature colourful laser bolts. But what would a real laser missile look like during flight, if we could only make it out? How would it illuminate its surroundings? The answers lie in a film made at the Laser Centre of the Institute of Physical Chemistry of the Polish Academy of Sciences in cooperation with the Faculty of Physics at the University of Warsaw. ...> Full Article|
|A cutting-edge paper by Professor George Fraser -- who tragically died in March this year -- and colleagues at the University of Leicester provides first potential indication of direct detection of Dark Matter -- something that has been a mystery in physics for over 30 years. ...> Full Article|
|Scientists have demonstrated, for the first time, a new type of mirror that forgoes a familiar shiny metallic surface and instead reflects infrared light by using an unusual magnetic property of a non-metallic metamaterial. Using nanoscale antennas, researchers are able to capture and harness electromagnetic radiation in ways that have tantalizing potential in new classes of chemical sensors, solar cells, lasers, and other optoelectronic devices. The work was published in the journal Optica today. ...> Full Article|
|Protons and neutrons that have briefly paired up in the nucleus have higher-average momentum, leaving less for non-paired nucleons. Researchers have now shown for the first time that this phenomenon exists in nuclei heavier than carbon, including aluminum, iron and lead and also surprisingly allows a greater fraction of protons than neutrons to have high momentum in these neutron-rich nuclei, contrary to long-accepted theories and with implications for ultra-cold atomic gas systems and neutron stars. ...> Full Article|
|The book 'Models of Life' is a non-traditional biophysics textbook and it describes how life functions and controls itself. The book is a journey of discovery into biological systems and provides an understanding of the principles of life and biological regulation. The book is written by a professor of biophysics, Kim Sneppen, Niels Bohr Institute at the University of Copenhagen. ...> Full Article|
|So far, experimental observations haven't clarified if the phenomenon at work in conventional superconductors -- at low critical temperature -- and involving the 'dressing' concept can also be seen in cuprates, but one study, published in Nature Communications and coordinated by Elettra Sincrotrone of Trieste, the University of Trieste and the University of Naples Federico II suggests that this might be the case. ...> Full Article|
The UK is playing a key role in an international project to develop a radical new type of nuclear power station that is safer, more cost-effective, compact, quicker and less disruptive to build than any previously constructed.Funded by the Engineering and Physical Sciences Research Council, as part of the RCUK Energy Programme, a team at the University of Cambridge is exploring whether the element thorium could help to meet the new design's fuel needs.

Minerals that endure in nature for millions of years are inspiring a Clemson University-led research team to explore whether new materials could be developed to encase nuclear waste for safe storage. The three-year project recently won an $800,000 research grant from the US Department of Energy's Nuclear Energy University Programs.

Developing the cloak of invisibility would be wonderful, but sometimes simply making an object appear to be something else will do the trick, according to Penn State electrical engineers.

Neutron scattering experiments at the ILL have revealed the existence of quantum selection rules in molecules, the first experimental confirmation of its kind.
Small molecules such as water and hydrogen were inserted into C-60 buckyballs to form rare compounds ideal for testing the predictions of quantum theory.
Similar confinement techniques could open the door to new insights about the quantum properties of molecules by providing a unique testing ground for quantum theory.

|Recently, US scientists attracted attention when they postulated that the decay rate of radionuclides depends on the flow of solar neutrinos and, thus, also on the distance from the Earth to the Sun. Their assumption was based, among other things, on older measurement data of the Physikalisch-Technische Bundesanstalt. PTB researchers have now definitively refuted the assumption of the Americans. ...> Full Article|

|University of Washington engineers have designed a concept for a fusion reactor that, when scaled up to the size of a large electrical power plant, would rival costs for a new coal-fired plant with similar electrical output. ...> Full Article|
|Using an ultrafast spectroscopy technique called time- and angle-resolved photoemission spectroscopy, Berkeley Lab researchers demonstrated a link between electron-boson coupling and high-temperature superconductivity in a high-Tc cuprate. ...> Full Article||
