>Next G7 at Trump's resort?
US President Donald Trump said on Monday he would probably host next year's Group of Seven summit of the major industrialized countries at one of his own properties - the Trump National Doral golf resort near Miami - but insisted he would not personally profit from the resort's selection.
The G7 countries take it in turn to stage the summit, often choosing locations that show off areas of natural beauty.
Trump said the Florida resort was a perfect choice, both due to its size and the fact it was just a five-minute drive from Miami airport.
Trump has attended three G7 summits, in Italy, Canada and France.
On each occasion, the meeting has been held far from any airport that can take his Air Force One plane, meaning he has had to be shuttled in by helicopter or by a smaller plane.
>Thinnest gold created
The newest form of gold created in a lab is the thickness of only two atoms, according to a new study.
It's only 0.47 nanometers thick, which is one million times thinner than a human finger nail.
The new gold is 2D as it is made up of two layers of atoms stacked on top of each other.
This makes it the thinnest unsupported gold ever created and it could be used in electronics and medical devices going forward.
Scientists suggest that the newest ultra-thin gold could be the foundation of artificial enzymes used in rapid medical diagnostic tests and even purification systems for water.
"This work amounts to a landmark achievement," said Sunjie Ye, study author and postdoctoral research fellow at the University of Leeds' Molecular and Nanoscale Physics group. "Not only does it open up the possibility that gold can be used more efficiently in existing technologies, it is providing a route which would allow material scientists to develop other 2D metals. This method could innovate nanomaterial manufacturing."
>Chinese culture in textbooks
Traditional Chinese culture is highlighted in the new textbooks on Chinese, history and ideology and politics for senior high school students in the coming semester.
