British scientists are joining colleagues from around the world today (Thursday March 30th 2006) at Fermi National Accelerator Laboratory (Fermilab) in the USA to share the first results from a new neutrino experiment. The Main Injector Neutrino Oscillation Search (MINOS) is designed to study ghostly particles called neutrinos and in particular to study how the three different types are able to transform one into the other. In their first data release, the MINOS team has already reached the sensitivity of previous experiments and provides independent confirmation that neutrinos have mass.
Professor Jenny Thomas, from UCL, said "The first MINOS result is a totally independent confirmation of the surprising fact that neutrinos are not massless. It opens up a whole field of study to understand why this is true and what it means to our understanding of the universe."
Neutrinos are vital to our understanding of the Universe. Nature provides for three types of neutrinos, yet scientists know very little about these ghost particles, which can traverse the entire Earth without interacting with matter. But the abundance of neutrinos in the universe, produced by stars and nuclear processes, may explain how galaxies formed and why antimatter has disappeared. Originally neutrinos were thought to have no mass, but previous experiments suggested that they can oscillate between the three types - a phenomenon which is only possible if they do have mass.

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...

Glaciers might seem rather inhospitable environments. However, they are home to a diverse and vibrant microbial community. It’s becoming increasingly clear that they play a bigger role in the carbon cycle than previously thought.
A new study, now published in the journal Nature Geoscience, shows how microbial communities in melting glaciers contribute to the Earth’s carbon cycle, a...
