The government, the Royal Society and the moral imperative of equality | Athene Donald
The Equality Act alone has not proved sufficient to solve the problems of diversity within the scientific workforceLast week Beverley Gibbs asked "Why is the Royal Society asking if there's a business case for diversity?" on the Guardian's Political Science blog. She did not intend it to be a rhetorical question. She genuinely seemed to find it inappropriate that anyone should seek to do any more than accept the moral position that equality should be a given. Her sub-heading expressed this forcefully, stating "When the Royal Society commissions research of this type it endorses the idea that diversity should be argued on e...

Fairytale of New Physics | Jon Butterworth | Life & Physics
There seems to be a minor rash of polemic at the moment on the theme "aren't scientists deluded/betraying science/living in fairytale-land".I've been sent a few books to read on the subject, and I started last week on BBC Radio 4's Start the Week, discussing the topic with Jim Baggott, Stephen Minger, Hilary Rose and Alan Little.Much of the ire is really directed at particle physics, so it seems a bit harsh to tar all science with the same brush. The fact that string theory hasn't made any testable predictions might be a fault of the whole of science, but it seems a fairly minor crime when stacked against longer life expec...

Why Greenland's darkening ice has become a hot topic in climate science
Darkening causes the snow to absorb more sunlight which in turn increases meltingLast July, a record melting occurred on the Greenland ice sheet. Even in some of the highest and coldest areas, field parties observed rainfall with air temperatures several degrees above the freezing point. A month before, it was as though Greenland expert Jason Box had a crystal ball; he predicted this complete surface melting in a scientific publication. Box's research then got broader public visibility after climate activist and writer Bill McKibben covered it in Rolling Stone magazine.The basic premise of Box's study was that observations...

Nanotechnology and religion: a complex relationship
There is much evidence that public views on nanotechnology will be shaped by religious beliefsIn the science fiction short story Halo, a panel of Muslim scholars discuss a strip of bacon made by a "molecular assembler", a device capable of producing the meat directly from individual atoms, instead of slicing the meat from an animal. All meat from a pig is forbidden according to Islam's halal laws. Synthetic bacon is identical to the real one, but it has never been part of a living pig. Is it still forbidden?"The story may look like a joke, but it shows how the capacity of nanotechnology to manipulate atoms may change the m...
