Using high-speed collisions between gold atoms, scientists think they have re-created one of the most mysterious forms of matter in the universe -- quark-gluon plasma. This form of matter was present during the first microsecond of the Big Bang and may still exist at the cores of dense, distant stars.
UC Davis physics professor Daniel Cebra is one of 543 collaborators on the research. His main role was building the electronic listening devices that collect information about the collisions, a job he compared to "troubleshooting 120,000 stereo systems."
Now, using those detectors, "we look for trends in what happened during the collision to learn what the quark-gluon plasma is like," he said. "We have been trying to melt neutrons and protons, the building blocks of atomic nuclei, into their constituent quarks and gluons," Cebra said. "We needed a lot of heat, pressure and energy, all localized in a small space."

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...
