LHC results put supersymmetry theory 'on the spot'
Results from the Large Hadron Collider (LHC) have all but killed the simplest version of an enticing theory of sub-atomic physics. Researchers failed to find evidence of so-called "supersymmetric" particles, which many physicists had hoped would plug holes in the current theory. Theorists working in the field have told BBC News that they may have to come up with a completely new idea.

Swede admits home-made atom experiment was 'crazy'
Swedish man who tried to set up a nuclear reactor in his kitchen at home has admitted his plan was "crazy". Richard Handl said he had just been "curious" and wanted to see if he would be able to split an atom.

Neutrino particle 'flips to all flavours'
Neutrinos are among the fundamental building blocks of matter. They swarm all about us. The Sun, for example, releases them in huge quantities when it fuses hydrogen to make helium - the raw nuclear process at its core. They are, however, very difficult to study because they interact so weakly with normal matter. Hence, their nickname - "ghost particles".

Nonetheless, scientists have been able to discern three flavours - electron neutrinos, muon neutrinos, and tau neutrinos. Previous research has characterised two forms of oscillations. The T2K experiment has now seen hints for a third transformation - that of a muon neutrino turning into an electron neutrino.

Japan pensioners volunteer to tackle nuclear crisis
A group of more than 200 Japanese pensioners are volunteering to tackle the nuclear crisis at the Fukushima power station. The Skilled Veterans Corps, as they call themselves, is made up of retired engineers and other professionals, all over the age of 60. They say they should be facing the dangers of radiation, not the young.

Japan steps up moves to cool stricken nuclear reactors
Japan says it is stepping up efforts to cool overheating fuel at the tsunami-hit Fukushima Daiichi nuclear plant.

Army helicopters dumped tonnes of water to try to prevent a meltdown of fuel rods. Water cannon are set to join the operation on the ground and it is hoped electricity will be restored soon.

Mars 'hopper' may run on nuclear decay and Martian CO2
Nuclear decay-driven machines could gather gases from the atmosphere of Mars, giving future robotic missions leaps of a kilometre, researchers say. A design concept in Proceedings of the Royal Society A outlines an approach to compress CO2 and liquefy it. The liquid would then be heated much as in a standard rocket, expanding violently into a gas to propel exploratory craft great distances.

Israeli PM Netanyahu pulls out of US nuclear summit
Israeli PM Benjamin Netanyahu has cancelled a visit to the US where he was to attend a summit on nuclear security, Israeli officials say. Mr Netanyahu made the decision after learning that Egypt and Turkey intended to raise the issue of Israel's presumed nuclear arsenal, the officials said. ... Israel has never confirmed or denied that it possesses atomic weapons. ... According to Israeli officials, Turkey and Egypt are planning to call on Israel to sign the nuclear Non-Proliferation Treaty (NPT).

Scientists plan to ignite tiny man-made star
Its goal is to generate temperatures of more than 100 million degrees Celsius and pressures billions of times higher than those found anywhere else on earth, from a speck of fuel little bigger than a pinhead. If successful, the experiment will mark the first step towards building a practical nuclear fusion power station and a source of almost limitless energy.

Laser fusion test results raise energy hopes
A major hurdle to producing fusion energy using lasers has been swept aside, results in a new report show. The controlled fusion of atoms - creating conditions like those in our Sun - has long been touted as a possible revolutionary energy source. However, there have been doubts about the use of powerful lasers for fusion energy because the "plasma" they create could interrupt the fusion.

Time to Scrap the NPT
There's only one country that has ever used nuclear weapons. There's only one country that has used nuclear weapons on civilian population centers. There's only one country that has ever threatened to use nuclear weapons on non-nuclear countries. There's only one country that has over 10,000 nuclear weapons many of which are on hair-trigger alert for enemies real or imagined. There's only one country that has developed a regime of low-yield, bunker-busting, usable nuclear weapons; stating that they could be legitimately used, not to deter aggression or to stave off an imminent threat, but simply to eliminate the suspicion of weapons programs. There's only one country that justifies unprovoked aggression (preemption) in its National Security doctrine; allowing it to attack any potential rival to its global dominance. There's only one country that currently occupies a Muslim nation of 25 million people without any proof of an imminent threat, weapons-systems, or territorial aggression.

E.Coli Cleans Up Nuclear Waste Cheaply, Efficiently
E. Coli does more than just make people sick — it can also be used to clean up nuclear waste, according to researchers at Birmingham University. The research team found that E. Coli bacteria effectively breaks down phytic acid (a phosphate storage material found in seeds) and releases the phosphate molecules, which bind to uranium to create a uranium phosphate precipitate. The precipitate can be harvested to recover uranium, and voila – no more nuclear waste.

Contract award for Jupiter probe
The Jupiter Icy Moons Orbiter (Jimo) is part of an ambitious mission to explore the three planet-sized Jovian moons Callisto, Ganymede and Europa. Designing the spacecraft poses a significant engineering challenge given the long distances involved. Controversially, the probe is to be powered by a nuclear propulsion system. Callisto, Ganymede and Europa are thought to harbour oceans of probable water beneath an icy crust. Jimo would be the first Nasa mission using nuclear electric propulsion. It would enable the spacecraft to orbit each icy world in turn, to perform extensive investigations of their composition, history, and potential for sustaining life.
