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

The study of archaeology has long been carried out using tools from the physics lab. Among these are carbon-14 dating, thermoluminescence dating, x-ray photography, x-ray fluorescence elemental analysis, CAT and MRI scanning, ground-penetrating sonar and radar, and many others. What is less well known is that archaeology has also made substantial contributions to physics. This is the story of old lead; why it is important to physics, and what ethical problems it presents to both sciences.  Read More

The Universe is big, and so is the challenge of understanding its large-scale structure (P...

Our knowledge of the large-scale structure of the Universe is gradually taking shape. However, our improved vision is mostly being statistically squeezed from huge data sets. Working backward from a statistical analysis to a putative fact about the (singular) Universe, to which statistics do not apply on a cosmological scale, is a dicey business. A case in point is a recent look at the biggest known structures in the Universe – large quasar groups.  Read More

qCraft brings quantum mechanics to Minecraft

“Anyone who is not shocked by quantum theory has not understood it,” Niels Bohr famously wrote. However, Minecraft players can now be slightly closer to parsing the perplexities of quantum theory, thanks to qCraft, a collaboration between Google and Dr. Spyridon Michalakis, a scholar of quantum mechanics. What does this new mod bring to the game? Only quantum teleportation, observer dependencies, and Schrödinger’s Cat, for starters.  Read More

The Nobel Medal awaits Francois Englert and Peter Higgs, winners of the 2013 Nobel Prize i...

Following a last-minute delay, physicists Francois Englert and Peter Higgs were today jointly awarded the 2013 Nobel Prize in Physics for their independent formulation of the Higgs mechanism, which supplies fundamental particles with mass. Their theory was recently validated by the discovery of a Higgs boson at CERN's Large Hadron Collider.  Read More

A schematic drawing of the Q-Weak experiment, showing how the scattered electrons are anal...

Researchers at the Jefferson Accelerator Laboratory have measured the weak charge of the proton for the first time. Early results from the Q-Weak experiment find the weak charge of the proton and the neutron to be consistent with predictions of the Standard Model.  Read More

Inside the tunnel of the Fermilab Main Injector proton accelerator - the driving power beh...

Particle physicists have been eagerly awaiting the first trials of the new Main Injector neutrino beam at the Fermi National Accelerator Laboratory in the US. This new facility is the result of reconfiguration of the Fermilab particle accelerators in the wake of the shutdown of the Tevatron in 2011. The new beam source is now online, and is well on route to becoming the world's most intense focused neutrino source.  Read More
