Why are there still so few black scientists in the UK?

There have been many reports but little action: UK university science departments need to do more to fix their serious diversity problem‘Not built for minorities to succeed’: black scientists on academia’s race problemThe Nobel laureate poet Sir Derek Walcott once said that the English language is nobody’s special property: “It is the property of the imagination.” Much the same could be said for science. It should be said. Except this isn’t quite so. Not yet.Data on who is doing science has rece...

Long-retracted papers are still cited in major journals

Even after scientific papers are retracted, hundreds of studies cite them as evidence. Roughly four retractions occur per 10,000 publications, mostly in medicine, life sciences, and chemistry journals.Journals should implement control measures that block the publication of papers that cite retracted papers. Andrew Wakefield's 1998 study linking vaccines with autism was riddled with holes. All 12 children involved were handpicked, which is antithetical to clinical research. The now-deregistered...

Did Earth eat the protoplanet it crashed into long ago?

Many experts believe that the Moon was formed when a protoplanet named Theia crashed into the Earth 4.5 billion years ago.One flaw in the theory has been that there's no remaining sign of Theia.New research suggests that Theia's mantle was subsumed by Earth and that large anomalous blogs of rock deep within the Earth are its remains. They're called "large low-shear-velocity provinces" (LLSVPs), and they're large anomalous globs of, well, some kind of rock deep inside the Earth. There's one unde...

Soil May Not Be Able to Keep Storing Carbon Dioxide as Emissions Increase
