Our planet is bombarded every second with a large number of chargeless, seemingly massless, particles that originate in nuclear fusion reactions that power the sun. Theyre called neutrinos.
According to The Standard Solar Model – the most substantiated model of the sun – the sun should emit around three times more neutrinos than are actually measured on Earth. They are a source of great interest for scientists who seek to better understand elementary particles and the physics of the sun. Indeed, one of the recipients of this years Nobel Prize in Physics was Raymond Davis, who first drew attention to the neutrino shortfall.
Three major research efforts (carried out by the underground large detector complexes at Sudbury Neutrino Observatory (SNO) in Canada, the U.S. National Underground Science Laboratory at Homestake and the Super-Kamikande in Japan ) have measured the number of neutrinos that actually reach Earth as a result of a specific reaction in the sun (thus the experiments are sensitive to only a small fraction of the solar neutrino spectrum). To better understand the shortfall of neutrinos on Earth, scientists have been trying to determine precisely how many neutrinos are emitted as a result of this reaction in the lab, so as to compare them with the number that actually reach Earth as measured by SNO, Kamiokande and Homestake.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
