New York: Teenager Bianca Andreescu stunned 23-time major champion Serena Williams 6-3, 7-5 to become Canada’s first Grand Slam singles champion here in the US Open finals.Williams was denied a record-equaling 24th Slam title as the 19-year-old Andreescu on Saturday became the youngest Grand Slam winner since Maria Sharapova at the 2006 US Open.While it was the fourth successive defeat in the finals for Willams, Andreescu tied Monica Seles, who lifted the 1990 Roland Garros trophy in her fourth major, for the record as the fastest player to grab a first Slam crown in the Open era.The morning showed the day as Williams by conceded her opening service game with successive double faults at Arthur Ashe Stadium. Andreescu did not let the gifts go in vain as she capitalized on them and took the first set as Williams handed her the first with another double fault.In the second set, Andreescu, who had failed to reach the main draw at Flushing Meadows in the previous two years, surged 2-0 ahead.Williams fought back from being 5-1 down to level 5-5 by hitting 14 of 17 points in a pulsating contest.The Canadian then held for 6-5 and Williams erred on a backhand to give Andreescu two more shots at the title. Williams hit an ace to save the first but Andreescu secured victory on the next with a crisp forehand return.

Brittle stars are included within a whole range of species, which contribute to knowledge in the medically important area of tissue regeneration. All brittle stars regenerate lose limbs, but the rate at which this occurs is highly variable and species-specific. One of the slowest rates of arm regeneration reported so far is that of the Antarctic Ophionotus victoriae. Additionally, O. victoriae also has an unusual delay in the onset of regeneration of about 5 months. Both processes are of interest for the areas of regeneration biology and adaptation to cold environments. One method of understanding the details of regeneration events in brittle stars is to characterise the genes involved. In the largest transcriptome study of any ophiuroid to date, we describe the results of mRNA pyrosequencing from pooled samples of regenerating arms of O. victoriae. The sequencing reads resulted in 18,000 assembled contiguous sequences of which 19% were putatively annotated by blast sequence similarity searching. We focus on the identification of major gene families and pathways with potential relevance to the regenerative processes including the Wnt/β-catenin pathway, Hox genes, the SOX gene family and the TGF beta signalling pathways. These data significantly increase the amount of ophiuroid sequences publicly available and provide candidate transcripts for the further investigation of the unusual regenerative process in this Antarctic ophiuroid.
