Zoomed-in image of barred spiral galaxy NGC 1365, around 60 million light years from Earth...

The Dark Energy Camera (DEC) has captured an initial batch of images as part of an ongoing quest to afford scientists with a better understanding of dark energy. The images were taken by the 570-megapixel behemoth from its location within the Chilean Andes on September 12 while undergoing a series of tests. Scientists hope it may soon help answer one of the biggest mysteries in physics: why the expansion of the universe is speeding up.  Read More

High-energy particle collision similar to those which may be giving us a glimpse of a new ...

In the mid-1930s, physicists thought they knew all the subatomic particles of nature - the proton, neutron, and electron of the atom. However, in 1936 the muon was discovered - a new particle having such surprising properties that Nobel laureate I.I. Rabi quipped "Who ordered that?" when informed of the discovery. Evidence that a new light boson may exist has recently been published. If the discovery is confirmed, such a boson is not part of the Standard Model of Particle Physics - potentially leading to another "Who ordered that?" moment for physicists.  Read More

A recent study of gamma-ray bursts by Professor Robert Nemiroff and his colleagues at Michigan Technological University provides the first strong evidence concerning the small-scale smoothness of spacetime. Oddly, this examination of the very small is accomplished by measuring a handful of gamma-rays after they traveled over ten billion light years.  Read More

500 terawatt shot -  The preamplifiers of the National Ignition Facility (Photo: Damien Je...

Researchers at the Lawrence Livermore National Laboratory's National Ignition Facility (NIF) have achieved a laser shot which boggles the mind: 192 beams delivered an excess of 500 trillion-watts (TW) of peak power and 1.85 megajoules (MJ) of ultraviolet laser light to a target of just two millimeters in diameter. To put those numbers into perspective, 500 TW is more than one thousand times the power that the entire United States uses at any instant in time. Pew-Pew indeed ...  Read More

A proton-proton collision observed by CMS produces two high-energy photons - behavior cons...

Numbers are yet to be crunched and the data analysis goes on, but one thing appears to be certain: scientists at CERN have discovered a new boson, and it's probably the Higgs particle, the missing particle of the Standard Model which is thought to lend all matter its mass. Both the ATLAS and CMS experiments at CERN observe a new particle with mass between 125 and 126 GeV, comfortably within the band of possible Higgs masses previously identified.  Read More

Using accelerometers the Tilt of Light seesaw can show users how their movement would impa...

If you're anything like us, you probably spent many an hour in your younger days bouncing up and down on a seesaw (or teeter-totter or teeter board, depending on where you grew up. And, even now, you might fight the desire to relive your childhood and jump on one as you walk past a playground. But Melbourne-based design group ENESS has created a seesaw, which comes complete with hundreds of LEDs and a physics engine to explore the forces at work on the familiar playground staple, that might just prove too difficult to resist.  Read More

Majorana fermions might be the sole component of the dark matter in our Universe (Photo:

Physicists at the Delft University of Technology, Netherlands, have achieved a milestone that might soon revolutionize the world of quantum computing, quantum physics, and perhaps shed new light on the mystery of the dark matter in our universe. Experimenting with nanoelectronics, a group led by Prof. Leo Kouwenhoven has succeeded in detecting the elusive Majorana fermion in the laboratory, without the need for a particle accelerator.  Read More

The 1.2 gigawatt motor-generator system which powers the outer coils on the LANL 100 Tesla...

Round performance numbers aren't necessarily important milestones, but they do exude an undeniable aura of accomplishment. This was the case when researchers at Los Alamos National Laboratory (LANL) used their largest pulsed magnet to crack the 100 Tesla mark (roughly 2 million times larger than the Earth's magnetic field) by generating a 100.75 Tesla magnetic pulse without damaging the magnet.  Read More

Qubits are fickle things, having a tendency to lose superposition under observation - reca...

A significant step on the path to quantum computing has been taken by an international team of researchers applying a 22-year old theory. They have succeeded in creating quantum bits within a semiconductor for the very first time.  Read More

A team of scientists led by the Max Planck Institute for Astrophysics (MPA) has produced the highest resolution map of the Milky Way's magnetic field ever produced. The map pools over 41,000 measurements from across 26 projects. "The resulting database is equivalent to peppering the entire sky with sources separated by an angular distance of two full moons," said Dr. Tracy Clarke of the Naval Research Laboratory.  Read More
