Researchers at Imperial College London have devised a method of achieving light to matter ...

In what could be a landmark moment in the history of science, physicists working at the Blackett Physics Laboratory in Imperial College London have designed an experiment to validate one of the most tantalizing hypotheses in quantum electrodynamics: the theory that matter could be created using nothing more than pure light.  Read More

HADES at the GSI in Darmstadt/Germany searches for dark matter candidates (Image: A. Schma...

Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) in Dresden, Germany have analyzed data from the HADES particle detector and concluded that the so-called "dark photons" are not the constituents of dark matter. Dark photons, or U bosons, are hypothetical particles that had thus far been the main candidate for that role, and this new result could make the search for the dark matter particle even more challenging than before.  Read More

Illustris simulation still frame centered on the most massive galaxy cluster existing toda...

As you might expect, the scale and complexities of the underlying physics means creating a realistic virtual universe would require some hefty computing power. A team of astronomers is claiming to have achieved this impressive feat using a computer simulation called "Illustris," which took five years to program and, for the first time, can recreate the evolution of the Universe in high fidelity.  Read More

Element 117 could become a new member of the periodic table of elements (Image: Shuttersto...

A new super-heavy element, temporarily called 117, may soon be making its way into the periodic table after being successfully created in a laboratory setting. Made up of 117 protons, the element matches some of the heaviest atoms ever observed and is around 40 percent heavier than a single atom of lead.  Read More

A rendering of a nanoparticle trapped in a laser and in thermal non-equilibrium (Image: Iñ...

It may be a little late for April Fool’s, but your skepticism is nonetheless warranted when reading that researchers have shown nanoparticles to disobey a fundamental law of physics which dictates the flow of entropy and heat in, it was believed, any situation. Specifically, researchers from three universities theoretically proposed then demonstrated that a nanoparticle in a state of thermal non-equilibrium does not always behave as larger particles might under the same conditions, with implications for various fields of research.  Read More

Artist's conception of a quantum atomic gas undergoing laser cooling in an ultracold refri...

Quantum physics likes the cold. In particular, macroscopic quantum phenomena such as superconductivity, superfluidity, and Bose-Einstein condensates (BECs) are only found at quite low temperatures. While current refrigeration methods can attain temperatures of a few nanoKelvins, attaining still lower temperatures is largely prevented by the need to support the cooling matter against the pull of Earth's gravity. Now NASA's Cold Atom Lab, scheduled for installation on the ISS in 2016, will aim for temperatures roughly four orders of magnitude smaller.  Read More

The spherical middle chamber of DarkSide-50 is filled with 7,000 gal of scintillator fluid

Like the Higgs Boson, dark matter is one of those things in the Universe that evidence points to, but is very difficult to pin down. A team of researchers is looking to verify the existence of this most elusive of ingredients that is thought to make up 23 percent of the Universe using powerful detectors buried deep in an Italian mountain.  Read More

Ball lightning appears at the impact point of a lightning strike, and its emission spectru...

A scientific team in China fortuitously recorded the first optical spectrum of an example of ball lightning. The ball lightning, which was accompanied by a cloud to ground lightning strike, appears to have consisted at least partially of vaporized soil from the location of the strike. While ball lightning may result from a variety of sources, this observation provides considerable evidence that the vaporized silicon explanation is valid, although possibly not unique.  Read More

Two astrophysicists from Michigan Technological University are using Twitter to search for...

At this juncture in time, humanity does not know how to travel into the past, or even if such a concept has any meaning. So if you are an astrophysicist who wants to uncover evidence of time travel, what do you do? If you're Michigan Technological University astrophysics professor Robert Nemeroff and his PhD student Teresa Wilson, you look for time travelers on Twitter.  Read More

Looking back on a year filled with scientific accomplishment

The close of 2013 gives us an excellent opportunity, though satiated with holiday feasts, to look back on a year that has been filled with scientific accomplishment. So it's time to get comfortable on your Binary Chair, sip your hot cocoa from a phase-change mug while your Foodini prints out a batch of cookies and reflect on science stories of note from the past year.  Read More
