Reconnection, the merging of magnetic field lines of opposite polarity near the surface of the sun, Earth and some black holes, is believed to be the root cause of many spectacular astronomical events such as solar flares and coronal mass ejections, but the reason for this is not well understood. Researchers at Los Alamos National Laboratory now have a new theory that may explain the instability and advance the understanding of these phenomena.

Study shows native bee species provide valuable services when allowed to flourish
Intensive, industrial-scale farming may be damaging one of the very natural resources that successful crops require: pollinating bees. A study by Princeton scientists found that native bee populations decline dramatically as agricultural intensity goes up.
In farms studied in and around the Sacramento Valley in California, concentrated farming appeared to reduce bee populations by eliminating natura
Study of planetary disks around T Tauri stars
If David Weintraub and Jeff Bary are right, there may be a lot more planets circling stars like the Sun than current models of star and planet formation predict.
The associate professor of astronomy at Vanderbilt and his graduate student are taking a critical look at T Tauri stars. These are stellar adolescents, less than 10 million years old, which are destined to become stars similar to the Sun as they age.

What molecule or particle passes the finishline first? A good way to split a fluid sample into its separate parts is: organize a contest in a micro-channel. The largest parts will pass the optical detector first, the smaller ones follow at short distance. This principle of ‘hydrodynamic chromatography’ is now also possible on a chip. ‘On-chip’ separation is faster, needs tiny samples and uses minimum of harmful solvents. Marko Blom developed this separation chip within the MESA+ research institute of
Novel methods of measuring magnetic fields outside the head give further insights to the functioning of the human brain. In his doctoral thesis “Estimating Neural Currents from Neuromagnetic Measurements”, Kimmo Uutela developed new methods for finding electrical activity of the brain, which enable easier identification of different brain areas. The Finnish Association of Graduate Engineers (TEK) and the Engineering Society in Finland (TFiF) honoured Uutela’s work with their joint doctoral thesis awa
An especially cold winter in Europe, lots of snow in Scandinavia or lots of rain in the Mediterranean are all symptoms of what meteorologists call the North Atlantic Oscillation, but a group of Penn State researchers has gone beyond the symptoms to try to decipher the dynamics of this atmospheric pattern.
“Some scientists argue that the impact of the NAO on global climate is comparable to El Nino,” says Dr. Sukyoung Lee, associate professor of meteorology. “However, most of the scientific co
