New laser-effect, discovered by scientists from the Vienna University of Technology, Princeton, Yale and ETH Zurich: If coupled, lasers can switch each other off, leading to a "laser blackout".

Receding Himalayan glaciers Almost six years ago, I was the editor of a single-topic issue on energy for Scientific American that included an article by Princeton University’s Robert Socolow that set out a well-reasoned plan for how to keep atmospheric carbon dioxide concentrations below a planet-livable threshold of 560 ppm. The issue came replete with technical solutions that ranged from a hydrogen economy to space-based solar. [More]

Authorities suspect outbreak originated at nearby Princeton University

DOE's Princeton Plasma Physics Laboratory (PPPL) is getting an earlier-than-expected start on a $94 million, nearly three-year project as the next stage of its mission to chart an attractive course for the development of nuclear fusion as a clean, safe and abundant fuel for generating electricity.

(PhysOrg.com) -- In the basement of Hoyt Laboratory at Princeton University, Alexei Tyryshkin clicked a computer mouse and sent a burst of microwaves washing across a silicon crystal suspended in a frozen cylinder of stainless steel.

Erez Lieberman Aiden was an undergraduate at Princeton University in 2000 when scientists announced with great fanfare that they had sequenced the first human genome , yielding a trove of information about what happens inside every human cell. But Aiden wondered what it would be like to see what was happening inside a human cell

Conventional wisdom would say that blocking a hole would prevent light from going through it, but Princeton University engineers have discovered the opposite to be true. A research team has found that placing a metal cap over a small hole in a metal film does not stop the light at all, but rather enhances its transmission.

Samuel Lazerson, an associate research physicist in advanced projects at the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL), has created a video simulation showing the intricate nature of a plasma pulse within an experimental fusion machine known as a heliotron. The simulation shows the superconducting field coils, saddle loops, and plasma of the Large Helical Device (LHD) at the National Institute for Fusion Science in Japan.

(PhysOrg.com) -- A thin sheet of plastic has been making headlines at Princeton as a magical flying carpet, after the publication of a paper describing experiments by the team with their prototype sheet of plastic that uses piezoelectric actuators and sensors to move.

Scientists looking to capture evidence of dark matter -- the invisible substance thought to constitute much of the universe -- may find a helpful tool in the recent work of researchers from Princeton University and New York University.

(PhysOrg.com) -- A new tool developed by nuclear engineers at Purdue University will be hitched to an experimental fusion reactor at Princeton University to learn precisely what happens when extremely hot plasmas touch and interact with the inner surface of the reactor.

An instrument developed by researchers at the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL) has enabled a team at the EAST fusion experiment in China to observe--in startling detail--how a particular type of electromagnetic wave known as a radiofrequency (RF) wave affects the behavior of hot ionized gas.

The USA is investing over 7.5 million dollars in the construction of the Wendelstein 7-X fusion device at Max Planck Institute for Plasma Physics in Greifswald. In the three-year project, starting in 2011, scientists from the fusion institutes at Princeton, Oak Ridge and Los Alamos are contributing auxiliary magnetic coils, measuring instruments and planning of special sections of the wall cladding for equipping the German fusion device – one of a total of nine projects in the Innovative Approaches to Fusion programme of the USA Department of Energy who will accordingly become a partner in the Wendelstein 7-X research programme.

(PhysOrg.com) -- A Princeton researcher and his international collaborators have used lasers to peek into the complex relationship between a single electron and its environment, a breakthrough that could aid the development of quantum computers.

(PhysOrg.com) -- A team of researchers from Columbia Engineering, the Italian National Research Council, Princeton University, University of Missouri, and University of Nijmegen (Netherlands) has developed an artificial semiconductor structure that has superimposed a pattern created by advanced fabrication methods that are precise at the nanometer scale.
