Possible signs of the Higgs remain in latest analyses (Update)

(PhysOrg.com) -- Two experiments at the Large Hadron Collider have nearly eliminated the space in which the Higgs boson could dwell, scientists announced in a seminar held at CERN today. However, the ATLAS and CMS experiments see modest excesses in their data that could soon uncover the famous missing piece of the physics puzzle.

Test paves way for 15,000-ton neutrino detector

Last month, the preparations for the assembly of the NOvA neutrino detector passed a pivotal test in an assembly building at the Department of Energy’s Fermi National Accelerator Laboratory.

Colossal magnetoresistance occurs when nanoclusters form at specific temperatures

(PhysOrg.com) -- Researchers at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory and the Universidad San Francisco de Quito in Ecuador have found that, at just the right temperatures, nanoclusters form and improve the flow of electrical current through certain oxide materials.

Scientists excited over hints of finding an elusive particle

Scientists are quivering with anticipation - flying halfway around the world for a close-up view of the action and devouring the latest updates from the blogosphere the way some girls track the doings of Justin Bieber.

The world’s smallest steam engine measures a few micrometers

What would be a case for the repair shop for a car engine is completely normal for a micro engine. If it sputters, this is caused by the thermal motions of the smallest particles, which interfere with its running

Slow road to stability for emulsions

By studying the behavior of tiny particles at an interface between oil and water, researchers at Harvard have discovered that stabilized emulsions may take longer to reach equilibrium than previously thought.

NASA satellite could reveal if primordial black holes are dark matter

(PhysOrg.com) -- The primary objective of NASA’s Kepler satellite, which was launched in March 2009 to orbit the Sun, is to search for Earth-like planets in a portion of the Milky Way galaxy. But now a team of physicists has proposed that Kepler could have a second appealing purpose: to either detect or rule out primordial black holes (PBHs) of a certain mass range as the primary constituent of dark matter.

LHC to narrow search for Higgs boson

Scientists at the world's largest atom smasher have new data that shows with greater certainty where to find a long-sought theoretical particle that would help explain the origins of the universe.

Atoms dressed with light show new interactions, could reveal way to observe enigmatic particle

(PhysOrg.com) -- Scientists at the Joint Quantum Institute (JQI) have for the first time engineered and detected the presence of high angular momentum collisions between atoms at temperatures close to absolute zero. Previous experiments with ultracold atoms featured essentially head-on collisions. The JQI experiment, by contrast, is able to create more complicated collisions between atoms using only lasers

Physicists find that an ultrahigh-energy proton looks like a black disk

(PhysOrg.com) -- What does a proton look like? The common answer to this question is that protons are much too small to scatter light, and since light is necessary for us to see things, protons do not “look” like anything. But in a new study, physicists have gathered sufficient evidence to show that, at least at very high energies, the proton is a black disk – sort of an elongated hockey puck.

Synthetic cricket pricks up its ‘ears’

The tiny hairs on the abdomen of a cricket have inspired researchers at the University of Twente, to make a new type of sensor which is ultra sensitive to air flows. These synthetic cricket hairs can now also be tuned very precisely for a certain range of frequencies: the hairs are 10 times more sensitive in this range

Computer simulations shed light on the physics of rainbows

(PhysOrg.com) -- Computer scientists at UC San Diego, who set out to simulate all rainbows found in nature, wound up answering questions about the physics of rainbows as well. The scientists recreated a wide variety of rainbows – primary rainbows, secondary rainbows, redbows that form at sunset and cloudbows that form on foggy days – by using an improved method for simulating how light interacts with water drops of various shapes and sizes.

Random noise helps make signals clearer

Scientists have shown the energy conditions, under which a weak signal supplied to a physical system emerges as a stronger signal at the output thanks to the presence of random noise (a process known as stochastic resonance), in a paper that has just been published in European Physical Journal B.
