  • England cricket chiefs back Ben Stokes in family tragedy story row

    first_imgLondon: England cricket chiefs rallied round star all-rounder Ben Stokes after he criticised a British newspaper report about a family tragedy more than 30 years ago. Tom Harrison, chief executive of the England and Wales Cricket Board (ECB), said he was “disgusted and appalled” by the front-page story in The Sun tabloid on Tuesday. Stokes, who helped England win the World Cup this year and played a starring role in the just-completed drawn Ashes series against Australia, has called the report “utterly disgusting” and said it touched on “deeply personal and traumatic events” involving the deaths of members of his New Zealand-based family more than 30 years ago.

In an ECB statement, Harrison said: “We, like the wider sporting world, are disgusted and appalled at the actions taken in revealing the tragic events from Ben’s past. “We are saddened that an intrusion of this magnitude was deemed necessary in order to sell newspapers or secure clicks. Ben’s exploits at Lord’s and Headingley cemented his place in cricket history this summer — we are sure the whole sport, and the country, stands behind him in support.” Also Read – Vijender’s next fight on Nov 22, opponent to be announced later In his own statement, Stokes said: “It is hard to find words that adequately describe such low and despicable behaviour, disguised as journalism. I cannot conceive of anything more immoral, heartless or contemptuous to the feelings and circumstances of my family. “For more than three decades, my family has worked hard to deal with the private trauma inevitably associated with these events and has taken great care to keep private what were deeply personal and traumatic events.” The Sun defended its approach, saying the story had received extensive media coverage in New Zealand at the time. A spokeswoman for the newspaper said: “The Sun has the utmost sympathy for Ben Stokes and his mother but it is only right to point out the story was told with the co-operation of a family member who supplied details, provided photographs and posed for pictures. “The tragedy is also a matter of public record and was the subject of extensive front-page publicity in New Zealand at the time. “The Sun has huge admiration for Ben Stokes and we were delighted to celebrate his sporting heroics this summer. He was contacted prior to publication and at no stage did he or his representatives ask us not to publish the story.” The story has also revived a debate about the ethics of the British press. Press regulation campaign group Hacked Off condemned the story. Hacked off board member Steve Barnett told BBC radio the story was “graphic evidence” of a newspaper “driving a coach and horses through their own code of conduct”. “He’s done absolutely nothing wrong and his own family history is dragged through the mud. I can’t see any justification for this other than the fact it will sell papers. It was a brutally commercial decision which took no account of their own code of conduct, which says everyone deserves respect for their private and family life,” Barnett said.last_img read more

  • Rare orchids mimic fungus to attract flies

    first_img Explore further (PhysOrg.com) — In a recent study published in the Proceedings of the National Academy of Sciences, Zong-Xin Ren from the Chinese Academy of Sciences and Peter Bernhardt from Saint Louis University discuss the lady’s slipper orchid (Cypripedium fargesii) and its ability to mimic the Cladosporium fungus in order to attract the flat-footed fly for pollination.

Cypripedium, a model lineage of nonrewarding orchid flowers, is pollinated primarily by bees. Here we present both an example of floral mimesis of fungus-infected foliage in orchids and an example of flat-footed flies (Agathomyia sp.; Platypezidae) as pollen vectors for angiosperms. Cypripedium fargesii is a nectarless, terrestrial, endangered orchid from southwestern China that requires cross-pollination to produce the maximum number of viable embryos. All insects caught entering or leaving the labellum sac were Agathomyia sp. carrying conidia of Cladosporium sp. on their mouthparts and legs, suggesting mycophagy. Blackish hairy spots on the upper surface of foliage may imitate black mold spots, serving as short-term visual lures. Some odor molecules also associated with Cladosporium cultures were isolated in the floral scent. Mimesis of fungus-infected foliage probably represents an overlooked but important option in angiosperm diversification, because there are three to five more Cypripedium spp. in southwestern China with the same mode of floral presentation and black-spotted hairy leaves.

Ren spent four summers climbing Yaoshan Mountain at 3,000 meters above sea level where a hundred or so of these flowers are found.When it comes to general flower pollination, the flowers usually offer something to the insects in order to attract them, be it food, water, or specific chemicals. However, the lady’s slipper orchid has nothing to offer potential visiting insects.While most flowers are usually pollinated by bees, Ren found the only insect to visit these orchids were the flat-footed fly. The flat-footed fly feeds on fungus and, like the orchid, is extremely rare.In order to attract the fly, the orchid mimics this fungus with the spots on its leaves and the odor it releases. The scent, similar to the smell of the fungus the flat-footed flies feed on, attracts the flies and the spotted leaves visually make it look as though it is infected with the particular fungus.When the fly enters the flower, it has to follow a specific path to get out, passing the pollinators which deposit clumps of pollen onto to the fly who then carries it to the next flower he visits. Ren also discovered that the flowers go one step further in that the center of the flowers are hairs (trichomes) that have evolved to look like the fungal spores.When the team analyzed the flies, they found fungal spores on the mouth, head, feet and pads, as well as the pollen from the flowers on their backs. Ren is planning further research to discover why the fungus carried by the flies does not infect the orchid. He also wants to know if the relationship between the flies and the orchid play any contributing factor to them both holding a rare status. Orchid wears the scent of deathlast_img read more
