An international team led by astronomers from Queen's University Belfast has identified the fastest ever star on an escape trajectory from the Milky Way – the white dwarf US708, which is traveling at a staggering 1,200 km per sec (746 miles per sec). The discovery of this star may shed light on the astronomical events that are vital to the calculation of distances in our universe. Read More
It’s been a common trope in films since the 1950s; a madman with an atomic bomb holds a city for ransom while the authorities race to find it in time. If such a thing ever does come about, Sandia National Laboratories is working on taking the suspense out of the situation with its Mobile Imager of Neutrons for Emergency Responders (MINER) – a nuclear device detector capable of narrowing a search to within a city block without door-to-door sweeps.

Dropping a nuclear warhead may not seem like a particularly bright idea, but earlier this year Sandia National Laboratories did just that. As part of the US government’s Life Extension Program (LEP) for its nuclear arsenal, the inert W88 ALT 370 warhead was dropped from a crane in New Mexico onto a slab of concrete to test the updated design’s safety.

With the Royal Navy (RN) working hard to cast off the "Jonah" reputation of its Astute class nuclear attack submarines, BAE Systems has successfully completed the latest RN boat Artful’s maiden dive. The third of the British A boats, which are billed as the most advanced submarine in the world, Artful submerged while tied to the BAE dock at Barrow in Furness, Cumbria as part of its commissioning process.

Researchers working at the University of Missouri (MU) claim to have produced a prototype of a nuclear-powered, water-based battery that is said to be both longer lasting and more efficient than current battery technologies and may eventually be used as a dependable power supply in vehicles, spacecraft, and other applications where longevity, reliability, and efficiency are paramount.

"Extremophile" bacteria have been found thriving in soil samples from a highly alkaline industrial site in Peak District of England. Although the site is not radioactive, the conditions are similar to the alkaline conditions expected to be found in cement-based radioactive waste sites. The researchers say the capability of the bacteria to thrive in such conditions and feed on isosaccharinic acid (ISA) make it a promising candidate for aiding in nuclear waste disposal. Read More
The problem with nuclear waste is that it needs to be stored for many thousands of years before it’s safe, which is a tricky commitment for even the most stable civilization. To make this situation a bit more manageable, Hitachi, in partnership with MIT, the University of Michigan, and the University of California, Berkeley, is working on new reactor designs that use transuranic nuclear waste for fuel; leaving behind only short-lived radioactive elements.

Sellafield is Europe's largest nuclear site and although operations including spent fuel management and nuclear waste storage continue on-site, power generation ceased in 2003. As part of the decommissioning process, the site's tallest chimney will now be demolished. Read More
Reappropriating structures or spaces for new uses is a common occurrence. Sydney's Goods Line and Battersea Power Station are both the focus of such projects. Now, architectural firm Matterbetter is asking for submissions to reimagine perhaps the most unusual thing yet: a Russian nuclear submarine. Read More
A group of researchers at New Jersey-based LPP Fusion is turning to crowdfunding to demonstrate net power gain from a nuclear fusion reactor. The scientists plan to do this using a technique which is relatively little-known, but which they claim is scientifically sound and only relies on well-established science. Given enough funding, the researchers say they could design a US$500,000, 5 MW reactor that would produce energy for as little as 0.06 cents per kWh, all by the end of the decade. Read More
