US scientists praise nuclear deal with Iran

Earlier this month my colleague Hamish Johnston published a blog post about the 70th anniversary of the bombing of Hiroshima, in which he reported on a piece by the science historian Alex Wellerstein about whether that first use of a nuclear weapon for non-testing purposes was justified.

It’s a hugely contentious issue – some say that the Hiroshima and Nagasaki bombings brought to an end a conflict that might otherwise have dragged on much longer, while others claim that a detonation well away from built-up areas would have been a better deterrent. Either way, the Hiroshima anniversary served as a pertinent reminder of the long and controversial role that physicists have played in designing and creating nuclear weapons, from the Manhattan Project onswards.

However, there have been plenty of physicists who have opposed the development of nuclear arms, including the Bulletin of the Atomic Scientists, which was founded in 1945 by Manhattan Project scientists who “could not remain aloof to the consequences of their work”. Another anti-nuclear group is the UK-based Scientists for Global Responsibility, whose executive director Stuart Parkinson is a physicist. Last week it published a report calling for the UK government not to replace its submarine-based Trident nuclear deterrent.

Now, a group of 29 leading US scientists and engineers, including six Nobel laureates, has written a two-page letter to US President Barack Obama backing the deal that the US – along with China, France, Germany, Russia and the UK – has struck with Iran to limit its development of nuclear weapons and permit inspections in return for a lifting of economic sanctions.

NASA badly hit by government shutdown

US citizens woke up this morning to the unbelievable news that their federal government would be shutting down all its “non-essential” services after the two houses of Congress failed to reach an agreement on a new budget. What this means in practice is that hundreds of thousands of federal employees will now face unpaid leave – and NASA’s workforce is among the most badly affected.

A staggering 97% of NASA’s 18,134 employees have been granted leave of absence, according to the Office of Management and Budget, quoted in the New York Times. This is the highest percentage of all the federal departments and agencies to be affected by the shutdown. Other federal workers affected include 94% of the 16,205 employees of the Environmental Protection Agency, along with 69% of the 13,814 working within energy.

“Due to the gov’t shutdown, all public NASA activities/events are cancelled or postponed until further notice. Sorry for the inconvenience,” read a rather understated tweet from NASA earlier today. Within the past few hours, the NASA website has also shutdown indefinitely.

Has Steven Chu been a good US energy secretary?

The Nobel laureate Steven Chu has recently announced that he is to resign from the role of US energy secretary. He will step down from the post at the end of February having served throughout the entire four years of Barack Obama’s first presidential term. During his reign, Chu has received strong plaudits from many Democrats and environmentalists. Obama has credited Chu for increasing the nation’s use of renewable energy while reducing its dependence on oil imports.

Others, however, have been critical of Chu. He is accused of specific failures such as the initiatives that led to the downfall of Solyndra – a solar-cell manufacturer that went bankrupt after receiving $535m in Department of Energy loan guarantees. A more general criticism when Chu was appointed was that he had very little political experience to carry out such a critical role in the governance of the US.
