One morning in New York
The 2010 Discovery Education 3M Young Scientist Challenge ended in a single session. Ten finalists, selected from hundreds of students across the country, competed in a series of live science challenges in New York City on the morning of 5 October, and the result was announced the same day.
That format puts a premium on thinking in public. The entry that gets a student to the final is prepared work; the final itself is a set of tasks performed in front of judges, on the clock, with no opportunity to redo them. McCarty came out of it with the title of America's Top Young Scientist and $50,000 in United States savings bonds, a stated cash value of $25,000.
The wound closure system
The release describes the winning entry in a single clause: an innovative wound closure system that better protects deep cuts. That is the entire published description of the work that won.
Nothing else about it is on the record here. The announcement does not say what the system was made of, how it held a wound, what it was tested on, how it compared with sutures, staples or adhesive, or whether it had been assessed by anyone outside the competition. No claim about its performance can be drawn from this record, and none is made on this page.
St. Paul and the prototype
The prize included more than money. The release states that McCarty would travel to St. Paul, Minnesota, to visit the 3M Innovation Center and work alongside the company's senior scientists to test and improve his prototype.
That is the part of the award with the most practical value to a middle-school inventor, and it is also the part that is hardest to verify afterwards. The release announces the visit as a component of the prize. It does not name a mentor, set a date, or promise any particular outcome, and no later source in this record records what came of it.
The other nine
The release names the rest of the podium. Sydney Clark, of Austin, Texas, homeschooled, finished second. Matthew Shimura, of Honolulu, Hawaii, a student at Punahou School, finished third. Liam O'Brien, Kai Klocke and Alexander Mataloni are recorded as tied across fourth and fifth place.
Six of the ten finalists are therefore named in the source used here; the other four are not. Naming the near-winners is a habit of press releases from science competitions, and it is useful: it fixes the size and the geography of the field that the winner beat.
What the competition is
The release calls the Discovery Education 3M Young Scientist Challenge the nation's premier science competition for middle-school students, open to grades five to eight. It is a company's description of a programme it sponsors, and it should be read as such, but the structure behind it is plain enough: a national entry, a shortlist of ten, a single winner, an annual title.
The competition still runs under the 3M name and still names one America's Top Young Scientist a year. What changes from year to year is the problem the winner chose to attack, from flood defence and waste-powered batteries to lead detection and cancer imaging.
What is documented — and what is not
The firm facts: Liam McCarty of Elm Grove, Wisconsin, a student at Brookfield Academy, won the 2010 Discovery Education 3M Young Scientist Challenge on 5 October 2010 in New York City, taking the title of America's Top Young Scientist, $50,000 in savings bonds with a $25,000 cash value, and a working visit to the 3M Innovation Center in St. Paul.
The gaps: no age or grade, no photograph, no technical description of the wound closure system, no testing, no measured result, no quotation from him, and no record of anything after October 2010, including what happened at St. Paul. Those blanks are left as blanks here.
