Artificial Embryos Created In The Laboratory.

A University of Cambridge team headed by Professor Zenricka Goetz used stem cells from mice to create an artificial embryo. However, it is unlikely that this embryo will develop into a healthy foetus, as other stem cells needed for that development are not present. Research on human embryos in the United Kingdom are strictly licensed, and currently it is illegal to keep them alive in laboratories for more than two weeks after fertilisation. However, experts have been renewing calls to allow experiments on embryos beyond the 14 days of development, in order to encourage further research towards medical breakthroughs. The Warnock Report of the Committee of Inquiry into Human Fertilisation and Embryology in 1984 settled on 14 days, when the embryo is a distinct individual and can no longer form a twin. This had never been challenged before until recently, as science had not found a way to physically support life in the lab beyond a week. But with recent research progress, where a way had been found to allow an early stage embryo to continue to develop for longer than13 days after fertilisation, and potentially longer, the quest for the relaxation of the 14-days rule had increased.

Cepheus: Trunk to Bubble.
Credit & Copyright: Rogelio Bernal Andreo. Star clusters, glowing nebulae and dark dust clouds abound in Cepheus, the royal constellation of the northern hemisphere spanning about 17 degrees. At the lower left, the large emission nebula catalogued as IC 1396, is hundreds of light-years across and about 3,000 light-years distant, containing a dark, winding, tendril-shaped feature known as the Elephant's Trunk. Near the top middle, the bright nebula is NGC 7380. At the upper right lies NGC 7635 (the Bubble Nebula) and star cluster M52. Associated with star formation, the sites are telltale markers along the region's complex of giant molecular clouds.

Sunflowers (Tournesols) is the name of two series of still life paintings by the Dutch painter Vincent van Gogh. The first series, executed in Paris in 1887, depicts the flowers lying on the ground, while the second set, executed a year later in Arles, shows a bouquet of sunflowers in a vase. In the artist's mind, both sets were linked by the name of his friend Paul Gauguin, who acquired two of the Paris versions. On March 30, 1987, Japanese insurance magnate, Yasuo Goto, paid the equivalent of US $39,921,750 for van Gogh's Still Life: Vase with Fifteen Sunflowers at auction at Christie's London. The painting currently resides at Seiji Togo Yasuda Memorial Museum of Modern Art in Tokyo.
