New floating microscopic device will allow researchers to study a wide range of cellular processes It´s a bit of a challenge. But, imagine a microscopic jet vacuum cleaner, the size of a pen nib that hovers over cell surfaces without ever touching them. Then imagine that the soap in the cleaning solution is replaced with various molecules that can be selectively delivered to the cells. This gives you a sense of a new device that researchers believe will serve as a powerful tool to...

  A breakthrough in understanding materials for next-generation electronic devices An international team of scientists has developed a novel X-ray technique for imaging atomic displacements in materials with unprecedented accuracy. They have applied their technique to determine how a recently discovered class of exotic materials — multiferroics — can be simultaneously both magnetically and electrically ordered. Multiferroics are also candidate materials for new classes...

(Ivanhoe Newswire) -- Women with high exposure to magnetic fields during pregnancy may have a higher risk of asthma in their children, according to this study. In this prospective study, researchers compared the daily magnetic field exposure of 801 pregnant women in Kaiser Permanente Northern California and used electronic medical records to follow their children for 13 years to see which children developed asthma. The study found that women with high MF exposure in pregnancy had a more than...

Physicists from Juelich, Kiel and Hamburg identify an atomic-scale magnetic lattice of cycloidal vortices in a thin metal film Physicists at Forschungszentrum Jlich and the universities of Kiel and Hamburg are the first to discover a regular lattice of stable magnetic skyrmions "“ radial spiral structures made up of atomic-scale spins "“ on a surface instead of in bulk materials. Such tiny formations could one day form the basis of a new generation of smaller and more efficient...

High speed plasma flows, often referred to as jets, are extremely common across the Universe. Such jets are observed in Earth's magnetosphere, in solar flares, and near various objects powered by black holes. New insights into the processes that modify these streams of ionized particles have been provided by rare in situ measurements of plasma flows made by ESA's Cluster spacecraft. Most visible matter in the Universe exists as plasma, an extremely hot gas in which atoms have been stripped of...

On June 22, 2011, the Helmholtz-Zentrum Dresden-Rossendorf set a new world record for magnetic fields with 91.4 Tesla. To reach this record, Sergei Zherlitsyn and his colleagues at the High Magnetic Field Laboratory Dresden (HLD) developed a coil weighing about 200 kilograms in which electric current create the giant magnetic field "“ for a period of a few milliseconds. The coil survived the experiment unscathed. With this record, we're not really that interested in reaching top field...

Physicists at the University of Arizona have achieved a breakthrough toward the development of a new breed of computing devices that can process data using less power In a recent publication in Physical Review Letters, physicists at the University of Arizona propose a way to translate the elusive magnetic spin of electrons into easily measurable electric signals. The finding is a key step in the development of computing based on spintronics, which doesn't rely on electron charge to digitize...

Research published this week in the journal Nature Communications shows that a light-sensitive protein found in the human eye can act as a "compass" in the magnetic field when implanted into the eyes of Drosophila (flies). The study showed that without their natural "magneto reception" protein, flies do not respond to a magnetic field. But after replacing the protein with a human version of the protein, their ability was restored. For migratory birds and some other animals, the ability to...

Scientists at George Mason University discovered that a phenomenon called a giant magnetic rope is the source for solar storms. The researchers made the discovery by using images from the NASA Solar Dynamic Observatory (SDO) spacecraft. Scientists had previously been unable to prove that the magnetic rope was the cause of solar storms. However, using images taken by the Atmospheric Imaging Assembly (AIA) telescope aboard the SDO, the team was able to pinpoint an area of the sun where a...


Word of the Day
penuche
  • A fudgelike confection of brown sugar, cream or milk, and chopped nuts.
'Penuche' is a variant of 'panocha,' a coarse grade of sugar made in Mexico. 'Panocha' probably comes from the Spanish 'panoja, panocha,' ear of grain.
