The ALPHA experiment at CERN

An international collaboration of 15 research institutions have produced and trapped antimatter atoms for the first time ever. The feat was part of the ALPHA experiment, which is being conducted at Switzerland’s CERN particle physics laboratory. It could be a step towards answering one the biggest cosmological questions of all time.  Read More

Conceptual design of the Fermilab holometer

Is reality a 3D hologram of a 2D universe? A team of researchers at the US Department of Energy's Fermilab are trying to take a measurement of the fabric of spacetime to show that there is a finite unit that makes up the universe. To do so, they have created the world's most accurate clock, the holographic interferometer or holometer.  Read More

Illustration of the dipolar variation in the fine-structure constant, alpha, across the sk...

Star Trek’s Scotty was adamant that you “canna change the laws of physics,” but, according to a report from a team of astrophysicists based in Australia and England, that could be exactly what happens in different parts of the universe. The report describes how one of the supposed fundamental constants of Nature appears not to be constant after all. Instead, this 'magic number' known as the fine-structure constant – 'alpha' for short – appears to vary throughout the universe.  Read More

The Hubble Space Telescope image of the inner region of Abell 1689, an immense cluster of ...

Dark energy has been described as the greatest puzzle of our universe. This mysterious force, discovered in 1998, is pushing the universe apart at ever-increasing speeds and astronomers have now devised a new method of measuring it. Using NASA's Hubble Space Telescope, astronomers were able to take advantage of a giant magnifying lens in space – a massive cluster of galaxies – to narrow in on the nature of dark energy. Their calculations, when combined with data from other methods, significantly increase the accuracy of dark energy measurements and may eventually lead to an explanation of what the elusive phenomenon really is.  Read More

CERN's new exhibition, the 'Universe of Particles' will introduce the intriguing world of ...

Do you know your quarks from your leptons? Need to brush up on wave-particle duality? CERN, the European Organization for Nuclear Research, has announced that it will open a permanent “Universe of Particles” exhibition on the ground floor of its incredible conference center - the Globe of Science and Innovation. The exhibition is designed to provide visitors with a fascinating insight into the world of particles and will feature a display on the Large Hadron Collider (LHC), the world’s largest accelerator – or as CERN describes it, “one of the most sophisticated scientific tools ever built to explore new territories of knowledge.”  Read More

Forty-five new radioisotopes found at Japan's heavy-ion accelerator facility

From RIKEN Research in Japan comes news today that 45 new radioisotopes have been discovered in just four days, more than the world's scientists typically find in an average year.  Read More

The Large Hadron Collider physics program has begun

After months of testing, the Large Hadron Collider research program has started at the European Organization for Nuclear Research (CERN) laboratory on the Franco–Swiss border. Accelerating particles and colliding them at 7 trillion electron volts - just half of its full capacity, but already three and a half times the energy previously achieved by the most powerful particle accelerator in the United States - scientists at LHC are now hoping to answer fundamental questions on the nature of our universe.  Read More

This image, taken in August 2009 by the WFC3 camera on the Hubble telescope, shows the old...

NASA's recently upgraded Hubble Space Telescope has made the deepest near-infrared image of the universe ever taken. Taken using a newly installed camera, the image shows deep space objects such as galaxies that formed only 600 million years after the Big Bang, making them the oldest galaxies ever seen. The image was taken with the Hubble’s new Wide Field Camera 3, which astronauts installed in May.  Read More

The successful restart of the Large Hadron Collider prompted scenes of jubilation

Contrary to claims by some scientists that the Large Hadron Collider (LHC) was being sabotaged from the future to save the world, it is back up and running. The LHC is now beyond the point where it was in 2008 when it had to be shut down just nine days after it had commenced sending beams around its 27km (17 mile) circuit on September 10 last year.  Read More

Our current “Standard Model” of cosmology (left), a model without dark energy, and a warm ...

Scientists have for some time postulated that "dark matter" could partially account for evidence of missing mass in the universe, while the hypothetical form of energy known as "dark energy" is the most popular way to explain recent observations that the universe appears to be expanding at an accelerating rate and accounts for 74 percent of the total mass-energy of the universe according to the standard model of cosmology. To better understand these two mysterious cosmic constituents scientists at the Los Alamos National Laboratory (LANL) are using Roadrunner, the world’s fastest supercomputer, to model one of the largest simulations of the distribution of matter in the universe.  Read More
