Speed of Light May Not Be Constant

4/30/2013 - Discovery News
The speed of light is constant, or so textbooks say. But some scientists are exploring the possibility that this cosmic speed limit changes, a consequence of the nature of the vacuum of space.

3/5/2013 - The New York Times (requires free registration)
At the Large Hadron Collider near Geneva, two armies of scientists struggled to close in on physics' most elusive particle.

Unparticle In Earth's Mantle? Physicists Peer Inside Planet In Effort To Confirm New Particle

2/27/2013 - Huffington Post
It's a good time to be a particle physicist. The long-sought Higgs boson particle seems finally to have been found at an accelerator in Geneva, and scientists are now hot on the trail of another tiny piece of the universe, this one tied to a new fundamental force of nature.

Physicists May Have Found Dark Matter, The Invisible Scaffolding Of Our Universe

2/24/2013 - The Huffington Post UK
Physicists may have finally found hard evidence for the existence of dark matter. Reports from the American Association for the Advancement of Science in Boston say the announcement could come within the next fortnight - if the data hold up.

Japan to Replace Nuclear Plant with World's Largest Wind Farm

1/18/2013 - Physics.org
Officials in Japan have announced plans for building the largest wind farm in the world, 10 miles off the coast of Fukushima—the site of the nuclear disaster that followed the earthquake and tsunami that struck the island nation in 2011. Projections call for developing a wind farm capable of producing 1 gigawatt of power.

Hubble Space Telescope Achieves Deepest Cosmic View Yet

12/13/2012 - BBC News
Astronomers using the Hubble telescope have observed deeper into space than ever before, reaching back in time to when the cosmos was less than 3% of its current age.

'Twisted Light' Idea Faces Doubts

11/8/2012 - BBC News
An idea to put a "twist" into radio and light waves to vastly boost the amount of data they can carry is called into question by a number of scientists.

Higgs Discovery: Giants of Physics Overlooked

7/11/2012 - NewScientist
Last week's discovery of the Higgs boson was the result of an international collaboration involving thousands of scientists, but it seems two nations feel their contribution has been overlooked.

Cosmic Discovery Week Ahead for Science, Perhaps

7/2/2012 - NewDaily.com
On Wednesday at the CERN particle physics research centre near Geneva, two separate teams of "Higgs Hunters"—a term they profess to hate—may well announce they have spotted it.

New Data on Elusive Particle Shrouded in Secrecy

6/20/2012 - The New York Times (requires free registration)
Physicists are crunching new data in the search for the Higgs boson; this is the boson’s last stand.

American Physics Dreams Deferred

5/22/2012 - The New York Times (requires free registration)
With budgetary constraints on space missions, American physicists are taking the back seat in areas like dark energy in which they have been pioneers.

Dark-Matter Mystery: Why Are 400 Stars Moving as if There's Nothing There?

5/1/2012 - TIME
A new study out of the European Southern Observatory claims that an established theory could be in trouble. Chilean astronomers took a look at the motion of 400-plus stars in the broadly defined neighborhood of the sun and concluded that the way they're all moving is inconsistent with conventional ideas about dark matter.

New Particle Discovered at CERN

4/30/2012 - ScienceDaily
Physicists from the University of Zurich have discovered a previously unknown particle composed of three quarks in the Large Hadron Collider particle accelerator. A new baryon could thus be detected for the first time at the LHC.

Super-Accurate Atomic Clock Sets Time Travel Record

4/27/2012 - NewScientist
A light signal sent between two German cities has set a new record for the transmission of an atomic clock's tick. The feat, involving an optical fibre more than 900 kilometres long, could pave the way for a global network of synchronised, ultra-accurate clocks capable of testing fundamental physics.

Survey Gets a Grip on Dark Energy

4/2/2012 - BBC News
Astronomers measure the precise distance to over a quarter of a million galaxies to gain new insights into the influence of dark energy on the Universe.

Nuclear Clock Progress Keeps on Ticking

3/26/2012 - Futurity.org
Scientists report advances toward a clock accurate to within a tenth of a second over 14 billion years—the age of the universe.

Flavor of the Ray: Neutrino Measurement May Help Solve Mystery of Matter's Domination over Antimatter

3/9/2012 - Scientific American
In less than two months of operation, an experiment at a Chinese nuclear power plant has measured one of the missing parameters that describes neutrino behavior.

Data Hint at Hypothetical Particle, Key to Mass in the Universe

3/7/2012 - The New York Times (requires free registration)
After 40 years, more evidence is being reported Wednesday that the end of the biggest manhunt in the history of physics might finally be in sight.

Ultracold Science Finds New Method to Get Even Colder

12/22/2011 - BBC News
Researchers have developed a clever way to achieve the lowest temperatures ever recorded on Earth.

‘Tantalizing Hints’ but No Direct Proof in Particle Search

12/13/2011 - The New York Times (requires free registration)
Two teams of scientists sifting debris from high-energy proton collisions in the Large Hadron Collider at CERN said Tuesday that they had recorded “tantalizing hints” of a long-sought subatomic particle known as the Higgs boson, whose existence is a key to explaining why there is mass in the universe. It is likely to be another year, however, before they have enough data to say whether the elusive particle really exists, the scientists said.

Has the Higgs Been Discovered? Physicists Gear Up for Watershed Announcement

12/12/2011 - Scientific American
Rumors are flying about a December 13 update on the search for the long-sought Higgs boson at Europe's Large Hadron Collider.

Study Rejects "Faster than Light" Particle Finding

11/21/2011 - Reuters
An international team of scientists in Italy studying the same neutrino particles colleagues say appear to have travelled faster than light rejected the startling finding this weekend, saying their tests had shown it must be wrong.

Neutrino Experiment Repeat at Cern Finds Same Result

11/18/2011 - BBC News
The team that found that neutrinos may travel faster than light has carried out an improved version of their experiment—and confirmed the result. If confirmed by other experiments, the find could undermine one of the basic principles of modern physics.

Dark Matter, Darker Still: The Cosmos' Greatest Mystery Deepens

10/27/2011 - TIME
You'd think cosmologists would know what makes up 80% of the universe. You'd be wrong.
