Researchers at the University of Warwicks Department of Physics have gained insight into the mysterious giant dark "tadpoles" that appear to swim towards the surface of the Sun during solar flares – enormous energy releases happening in the atmosphere of the Sun.
The tadpoles – colossal physical structures with dark heads and attendant wiggly tails that seem to swim sunwards against tides of hot matter being thrown away from the Sun during flares – have puzzled astrophysicists for several years, as they are so unlike any other phenomena observed on the Sun.
University of Warwick researchers Dr Valery Nakariakov and Dr Erwin Verwichte believe they have managed to understand the physics of this process. They analysed observations obtained with NASAs “Transition Region And Coronal Explorer” (TRACE) space mission and put forward the idea that the wiggles of the tadpoles’ tails are huge waves – similar to the flying of flags in the wind - though, these solar wiggles are several times larger than the Earth. The scientists think that the waves are produced by a peculiar physical mechanism known as "negative energy waves", when waves suck energy from the medium they propagate through.

Max Planck researchers revel the nano-structure of molecular trains and the reason for smooth transport in cellular antennas.
Moving around, sensing the extracellular environment, and signaling to other cells are important for a cell to function properly. Responsible for those tasks...
Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
