Gitanjali Rao, a seventh grader from Colorado, has been awarded the title of “America’s top young scientist” for designing a compact device to detect lead in drinking water, which she believes can be faster and cheaper than other current methods.

The 11-year-old’s invention was inspired by the water crisis in Flint, Michigan, where cost-cutting measures led to tainted drinking water that contained lead and other toxins. It also won her a $25,000 prize, for which Rao already has plans: “I plan to use most of it in developing my device further so that it can be commercially available soon,” she said

Rao who attends the STEM School in Highlands Ranch, Colorado, originally submitted the idea to the Discovery Education 3M Young Scientist Challenge, an annual youth science and engineering competition for middle school students in the US, inaugurated in 2008. She was awarded a 3-month mentorship with Kathleen Shafer, a research specialist who develops new plastics technologies: “Gitanjali’s concept was at a very early stage at the beginning of our mentorship. She had thought of this idea earlier this year, only a few weeks before the submission deadline,” Shafer said.

Crystal Palace turn down two bids of £35m and £40m before United agreed to Palace’s demand to pay a higher portion of the fee up front.

Bissaka has returned from the Under-21 European Championship after England’s early exit, will become the club’s second summer signing after Dan James and the fourth most expensive in their history after Paul Pogba, Romelu Lukaku and Angel Di Maria.

Ole Gunnar Solskjaer finally got his man after weeks of negotiations between executive vice-chairman Ed Woodward and Palace chairman Steve Parish.

Solskjaer is also keen to add a centre-back and at least one midfielder to his squad before the new season starts in August.

He will compete with Ashley Young and Diogo Dalot to start at right-back for United next season.
