Dubnium(nominated by R8R) is a synthetic chemical element with symbol Db and atomic number 105. Dubnium is highly radioactive: the most stable known isotope, dubnium-268, has a half-life of just over a day. This greatly limits the extent of research on dubnium. Dubnium does not occur naturally on Earth and is produced artificially.
Buckton Castle(nominated by Richard Nevell) was a medievalenclosure castle near Carrbrook in Stalybridge, Greater Manchester, England. It was surrounded by a 2.8-metre-wide (9 ft) stone curtain wall and a ditch 10 metres (33 ft) wide by 6 metres (20 ft) deep. Though it only survives as buried remains and is overgrown with heather and peat, Buckton is one of the earliest stone castles in North West England. It was probably built and demolished in the 12th century. The earliest surviving record of the site dates from 1360, by which time it was lying derelict. The few finds retrieved during archaeological investigations indicates that Buckton Castle may not have been completed.
WestJet Encore(nominated by Vanguard10) is a Canadian regional airline that began operations in 2013. It is owned by WestJet Airlines, Ltd. which also is the holding company for WestJet Airlines. The airline is headquartered in Calgary, Alberta. In response to internal marketing studies about future growth limitations by WestJet Airlines operating only Boeing 737 aircraft, WestJet Encore was formed to allow increased frequency of flights by using smaller aircraft, as well as to commence service to routes with less traffic. The airline operates Bombardier Q400 NextGen aircraft, a variant of the Bombardier Dash 8. The airline is the fourth largest operator of the Bombardier Q400 series. Pilot bases are in Calgary and Toronto, where many WestJet Encore flights operate. Air service originally started in Western Canada, but routes in the eastern half of the country were added later.

The men's race was the final event of the day and completed a whitewash as Cambridge won, their second victory in three years, and taking the overall record to 83–80 in their favour. The races were watched by around a quarter of a million spectators live, and were broadcast around the world by a variety of broadcasters. The two main races were also available for the second time as a live stream using YouTube.

The cooperative pulling paradigm(nominated by Edwininlondon) is used by ethologists, comparative psychologists, and evolutionary psychologists try to understand how cooperation works and how and when it may have evolved. Two or more animals pull rewards towards themselves via an apparatus that they can not successfully operate alone. Chimpanzees, bonobos, orangutans, capuchins, tamarins, wolves, elephants, ravens, and keas appear to understand the requirements of the task.
