John Harries obituary
Physicist who designed and developed innovative instruments that provided evidence of changes in the Earth ’s atmosphereThe consensus on how human activity is changing our climate is now so comprehensive that it is easy to forget that crucial to building the scientific understanding has been the acquisition over decades of many careful environmental measurements. John Harries, who has died aged 76, was involved in designing, developing and deploying instruments that were placed on aeroplanes, balloons and satellites to measure the heat radiation emitted by the Earth. His work resulted in the first direct observational ev...

Lazy movie stereotypes that put women off science | Brief letters
Film-makers should retire the cliche of the lone male scientific genius, saysRachel Youngman of the Institute of PhysicsIt is hardly surprising to hear that there is a lack of diversity in the portrayal of artificial intelligence researchers in movies (Just nine out of 116 AI professionals in key films are women, study finds, 13 February). There is too often an assumption in popular culture that a scientist, inventor or programmer is male, nearly always white and, of course, a driven, eccentric genius. It is a deeply damaging and lazy stereotype, and needs to be dispatched to the dustbin of social and creative history.At t...

Black holes ‘contain dark energy that drive expansion of universe’
International scientists propose black holes as source for dark energy, created when stars collapseNothing sucks more than a supermassive black hole, but according to a group of researchers, the enormous objects found at the heart of many galaxies may be driving the expansion of the cosmos.The radical claim comes from an international team who compared growth rates of black holes in different galaxies. They conclude that the spread of masses observed could be explained by black holes bearing cores of “dark energy”, the mysterious force behind the accelerating expansion of the universe.Continue reading...
