In 1704, Newton published Opticks, in which he expounded his corpuscular theory of light. He considered light to be made up of extremely subtle corpuscles, that ordinary matter was made of grosser corpuscles and speculated that through a kind of alchemical transmutation "Are not gross Bodies and Light convertible into one another, ...and may not Bodies receive much of their Activity from the Particles of Light which enter their Composition?

Autism
‘Social symptoms in autistic children may be caused by hyper-connected neurons
The brains of children with autism show more connections than the brains of typically developing children do. What's more, the brains of individuals with the most severe social symptoms are also the most hyper-connected. The findings reported in two independent studies are challenge the prevailing notion in the field that autistic brains are lacking in neural connections.’

‘Autistic brains create more information at rest, study show
New research finds that the brains of autistic children generate more information at rest -- a 42 percent increase on average. The study offers a scientific explanation for the most typical characteristic of autism -- withdrawal into one's own inner world. The excess production of information may explain a child's detachment from their environment.’

New catalyst to convert greenhouse gases into chemicals
Researchers have developed a highly selective catalyst capable of electrochemically converting carbon dioxide -- a greenhouse gas -- to carbon monoxide with 92 percent efficiency. The carbon monoxide then can be used to develop useful chemicals.'

Water
‘Scientists using the Herschel space observatory have made the first definitive detection of water vapor on the largest and roundest object in the asteroid belt, Ceres.
Plumes of water vapor are thought to shoot up periodically from Ceres when portions of its icy surface warm slightly. Ceres is classified as a dwarf planet, a solar system body bigger than an asteroid and smaller than a planet.
Herschel is a European Space Agency (ESA) mission with important NASA contributions.
"This is the first time water vapor has been unequivocally detected on Ceres or any other object in the asteroid belt and provides proof that Ceres has an icy surface and an atmosphere," said Michael Küppers of ESA in Spain, lead author of a paper in the journal Nature.’
