Arena X-Glide

Arena X-Glide is a swimsuit from the Arena brand, made of pure polyurethane that causes a swimmer to slide through water faster when swimming. One notable example of the efficacy of this suit design is that of Paul Biedermann of Germany who wore the suit in the 2009 World Championships, breaking two world records; the design of the suit covers the whole torso and the legs with the impermeable polyurethane, thereby exposing less skin to the water and improving the swimmer's buoyancy and streamlined shape. This reduces the drag a swimmer experiences as he or she moves through the water. According to Rick Sharp, an exercise physiologist at Iowa State University, "The Speedo team came up with a design that put panels of polyurethane over parts of the body that produce the highest drag. Another part is the suit design: You don't want a suit that traps water as it flows around the swimmer, yet another innovation is to use material that squeezes and slims down swimmers "so the skin doesn't wobble around as they go through the water."

Pieces of fabric were put through wind-tunnel tests to check for drag. Programmers used computational fluid dynamics to model the suits' aerodynamic qualities, as if they were trying to figure out how a brand-new jet will fly. Swimmers put the designs to real-world tests in tanks and pools. Following the incredible results the new Speedo LZR Racer swimsuit produced in the Beijing Olympics, Italian swimsuit makers Arena and Jaked responded by both developing suits that one-upped the Speedo by using pure polyurethane. There was a great deal of controversy in the swimming world surrounding polyurethane swimsuits, strict rules banning these types of swimsuits in professional swimming were put into place. After Biedermann's wins in the 2009 World Championships, Michael Phelps' trainer suggested that Phelps boycott international swimming competitions until the suit is banned. Biedermann's breaking of both Ian Thorpe's 400m world record as well as Phelps's 200m record have been attributed to the superiority in the design of his swimsuit.

Michael Phelps speculated that the new rules banning polyurethane will level the playing field once more, stating: Following the December 2008 European Short Course Championships in Croatia, where 17 world records fell, it was felt there was a need to modify the rules surrounding swimsuits. The combined effects of the LZR both compressing the body and trapping air for buoyancy led to many competitors who used the LZR wearing two or more suits for an increased effect; this led to some claiming that the LZR was in effect "technological doping."At their meeting in Dubai in March 2009, FINA stipulated that swimsuits should not cover the neck, must not extend past the shoulders and ankles, limit the suits' thickness and buoyancy. In a statement FINA stated that: The LZR Racer and all other Speedo Fast Skin Competition Suits were approved; however other suits like the BlueSeventy Nero Comp were banned first and afterwards released, too. In an abrupt reversal of opinion, the FINA Congress voted unanimously to revert its previous policy and ban all body-length swimsuits.

The decision was taken in Rome on July 2009, during the 2009 World Aquatics Championships. The new policy states that men's swimsuits may maximally cover the area from the waist to the knee, women's counterparts from the shoulder to the knee, they ruled that the fabric used must be a textile. The new regulations took effect in January 2010. USA Swimming, the United States governing body, made the date where all these suits will be illegal October 1, 2009. FINA has released an outline of the legal suits to wear. Among the suits on this list there is the Nike Swift, the Speedo FS PRO, the Speedo LZR.

Alexander John "Sandy" Trees, Baron Trees is a Professor of veterinary parasitology and a Crossbench member of the House of Lords. Trees was born on 12 June 1946, in Middlesbrough and spent his childhood in Scunthorpe, North Lincolnshire, he was educated at Brumby Junior School and at Brigg Grammar School between 1957 and 1964. In 1969, he graduated from Royal School of Veterinary Studies, University of Edinburgh with a Bachelor of Veterinary Medicine and Surgery and therefore qualified as a vet. Upon graduation, Trees undertook a research expedition to Kenya in 1969 to 1970, he spent a year as a practising veterinarian in Derby, England. This accumulated into completing a Doctor of Philosophy on bovine babesiosis, he joined the veterinary pharmaceuticals company Elanco in Italy. He was veterinary advisor for the Middle East from 1977 to 1979, veterinary advisor for the Middle East and Africa from 1979 to 1980, Head of Animal Science in the Middle East and Africa in 1980. In 1980, he joined the University of Liverpool as a lecturer of veterinary parasitology.

He was Head of the Department of Veterinary Parasitology from 1992 to 2001. In 1994, he was made Professor of veterinary parasitology and appointed Head of the Parasite and Vector Biology Division at the Liverpool School of Tropical Medicine, he was Dean of the Faculty of Veterinary Science, University of Liverpool from 2001 to 2008. In 2011, he retired from the University, he was Vice-President of the European Veterinary Parasitology College from 2006 to 2009. He was President of the Royal College of Veterinary Surgeons from 2009 to 2010. From 2011, he is a member of the Executive Committee of the World Association for the Advancement of Veterinary Parasitology, he has been Chairman of the Moredun Research Institute since December 2011. In March 2016 Trees was elected an Honorary Fellow of the Royal Society of Edinburgh, the RSE's highest class of Fellowship. On 3 July 2012, Trees was made a life peer as Baron Trees, of The Ross, was introduced in the House of Lords on 12 July 2012, where he sits as a Crossbench, or independent, peer.

He is only the second veterinary surgeon to become a member of the House of Lords after Lord Soulsby. Baron Trees made his maiden speech in the House of Lords in January 2013 on the Leveson debate.
