Hydrogen protects nuclear fuel in final storage
When Sweden's spent nuclear fuel is to be permanently stored, it will be protected by three different barriers. Even if all three barriers are damaged, the nuclear fuel will not dissolve into the groundwater, according to a new doctoral dissertation from Chalmers University of Technology in Sweden. view more (2009-04-27)
Underwater wings for tidal power
A NOVEL machine that generates electricity from marine tides will be put to the test off the Scottish coast next year. Called the Snail, it uses the flow of water over wings to anchor it to the seabed. This will allow it to operate at a greater range of sites than rival models, its designers say. Tidal flows have the potential to supply large... view more... (2003-09-24)
A new approach to engineering for extreme environments
Composite materials such as fiberglass, which take on a mix of properties of their constituent compounds, have been around for decades. Now, an MIT materials scientist is taking composites to the nanoscale, where entirely new properties, not found in any of the original compounds, can emerge. view more (2009-06-30)
New RFID technology tracks and monitors nuclear materials
Radio frequency identification (RFID) devices have widely been used for tracking for years; recently, scientists from U.S. Department of Energy's (DOE) Argonne National Laboratory have developed a unique tracking technology that also monitors the environmental and physical conditions of containers of nuclear materials in storage and transportation. view more (2009-03-25)
Fusion to play part in UK energy strategy
Fusion is one of the research areas picked out for energy investment from the UK government by the House of Commons Science and Technology Committee in its Report on Energy Research published yesterday. The report "Towards a non-carbon fuel economy: research, development and demonstration" looks at the state of development of different... view more... (2003-04-04)
Spallation Neutron Source sends first neutrons to 'Big Bang' beam line
New analytical tools coming on line at the Spallation Neutron Source, the Department of Energy's state-of-the-art neutron science facility at Oak Ridge National Laboratory, include a beam line dedicated to nuclear physics studies. view more (2008-10-10)
'Double crystal fusion' could pave the way for portable device
Researchers at Rensselaer Polytechnic Institute have developed a tabletop accelerator that produces nuclear fusion at room temperature, providing confirmation of an earlier experiment conducted at the University of California, Los Angeles (UCLA), while offering substantial improvements over the original design. view more (2006-02-14)
Royal Medals for scientific achievement
The Royal Society - the UK's independent academy for science - has announced the winners of its Royal Medals for 2002. The three winners receive the awards in recognition of their achievements in the fields of cancer research, nuclear magnetic resonance and the epidemiology of smoking and chronic disease. Professor Suzanne Cory receives her Royal... view more... (2002-07-30)
Slight risk of leukaemia among UK nuclear test veterans "cannot be ruled out"
Nuclear test veterans are not at increased risk of premature death and developing cancer, overall, finds research in Occupational and Environmental Medicine. But the possibility that they may have a slightly increased risk of leukaemia, "cannot be ruled out," the authors conclude. The researchers from the UK's National Radiological... view more...

Wind, water and sun beat biofuels, nuclear and coal for clean energy, Stanford researcher says
The best ways to improve energy security, mitigate global warming and reduce the number of deaths caused by air pollution are blowing in the wind and rippling in the water, not growing on prairies or glowing inside nuclear power plants, says Mark Z. Jacobson, a professor of civil and environmental engineering at Stanford. view more (2008-12-11)
New co-chair of atomic scientists calls on US administration to reduce nuclear threat
Lawrence Krauss, a theoretical physicist and cosmologist at Arizona State University, will co-chair the Board of Sponsors of the Bulletin of Atomic Scientists with Nobel Laureate Leon Lederman. Together they plan to re-energize a national discussion on the reduction of nuclear weapons stockpiles, and a commitment to fight proliferation and... view more... (2009-01-14)
ETH Researchers Visualize the Binding of Proteins to the Nuclear Surface
Not only the genetic information of individual cells, but also that of the entire organism is stored within the cell nucleus. Each cell of a multicellular organism, e.g. man, contains the identical DNA sequences. The communication between the cell nucleus and the remainder of the cell is thus decisive for the correct functioning of the cells and... view more... (2003-01-15)
30 Years of European R&D for Reliable and Effective Nuclear Material Control
Controlling nuclear materials to ensure that they are not diverted from peaceful intent into nuclear weapons use or unknown purposes is and will continue to be a vital political and technical matter at National, European and Global scales. A control system, called "Safeguards", which consists of accounting, reporting, and verification by... view more... (1999-04-29)
Doomsday clock moves forward 2 minutes
The Bulletin of the Atomic Scientists (BAS) is moving the minute hand of the Doomsday Clock today from seven to five minutes to midnight. view more (2007-01-18)
Location matters, even for genes
Moving an active gene from the interior of the nucleus to its periphery can inactivate that gene report scientists from the University of Chicago Medical Center in an article to be published early online Feb.13, 2008, in the journal Nature. view more (2008-02-14)
Wnt signalling protein Dishevelled acts in the nucleus, not just in the cytoplasm
Researchers have identified that Dishevelled doesn't only function in the cytoplasm and at the cell membrane - it must also pass into the nucleus. A study published today in Journal of Biology reveals that Dishevelled, a key player in the Wnt/beta-catenin signalling pathway, has to be localised in the nucleus to perform a key aspect of its... view more...

Compound removes radioactive material from power plant waste
Strontium 90 is a common radioactive by-product of fission in nuclear power plants. When extracted from the reactor along with other isotopes, a mixture is created made up of the radioactive material and inert ions like sodium and calcium. view more (2008-03-13)
Hospitals could reduce unnecessary tests for cardiac diagnostic imaging
Hospitals that perform cardiac nuclear stress testing under published national practice guidelines could reduce unnecessary testing and, potentially costs, according to a Henry Ford Hospital study. view more (2008-09-15)
Quatratran - Helping to make The World a safer place
Since the development of superconducting electronic devices there has been a need to develop a three terminal transistor like device sensitive enough to measure small voltage and current signals typical of those associated with single electron and photon events. A group of researchers in the Department of Particle & Nuclear Physics at Oxford... view more... (2004-02-19)
Geologist troubleshoots silica problem at geothermal plants
In the debate over alternative energy resources, geothermal technology has received scant media attention. Advocates call it one of the cleanest, sustainable energy resources available. However, steep construction, equipment and drilling costs have prevented more widespread development of geothermal technology. view more (2007-03-14)
