Student finds incubators have wildly varying magnetic fields

Lucas Portelli, a doctoral student in the University of Colorado Boulder's Department of Electrical, Computer and Energy Engineering, wanted to know how electromagnetic fields affect living things.

The Higgs boson looks just like Marc Sher said it would. Now what?

It turns out that the Higgs boson looks exactly like Marc Sher always said it would, and now he's a little bummed.

NASA Teams With School, Theatre to Teach Students Science, Math

Elementary school students will get a unique hands-on science lesson thanks to a partnership between NASA, Hampton city schools and a local movie/entertainment complex.

Space Station Astronauts Land Safely in Kazakhstan

Three members of the Expedition 34 crew undocked from the International Space Station and returned safely to Earth on Friday, wrapping up a mission lasting more than four and a half months. Expedition 35 now is under way.

Swarm intelligence: Study uncovers new features of collective behavior when overcrowding sets in

Swarming is the spontaneous organised motion of a large number of individuals. It is observed at all scales, from bacterial colonies, slime moulds and groups of insects to shoals of fish, flocks of birds and animal herds. Now physicists Maksym Romenskyy and Vladimir Lobaskin from University College Dublin, Ireland, have uncovered new collective properties of swarm dynamics in a study just published in European Physical Journal B.

New microscope measures nanomagnet property vital to 'spintronics'

Researchers have developed a new microscope able to view and measure an important but elusive property of the nanoscale magnets used in an advanced, experimental form of digital memory. The new instrument already has demonstrated its utility with initial results that suggest how to limit power consumption in future computer memories.

Physics duo discover 13 new solutions to Newtonian three-body orbit problem

(Phys.org) —Physicists Milovan Šuvakov and V. Dmitrašinović of the Institute of Physics, Belgrade in Serbia have discovered using computer simulations, 13 new solutions to the three-body problem—predicting patterns that describe how three bodies will orbit around each other in space in a repeating pattern. The two describe how they came up with their solutions using computer simulations in their paper published in Physical Review Letters.

Scientists generate thousands of simulations to analyze flood of data from the Planck mission

(Phys.org) —To make the most precise measurement yet of the cosmic microwave background (CMB) – the remnant radiation from the big bang – the European Space Agency's (ESA's) Planck satellite mission has been collecting trillions of observations of the sky since the summer of 2009. On March 21, 2013, ESA and NASA, a major partner in Planck, will release preliminary cosmology results based on Planck's first 15 months of data. The results have required the intense creative efforts of a large international collaboration, with significant participation by the U.S.

Smallest vibration sensor in the quantum world

Carbon nanotubes and magnetic molecules are considered building blocks of future nanoelectronic systems. Their electric and mechanical properties play an important role. Researchers have now found a way to combine both components on the atomic level and to build a quantum mechanical system with novel properties.
