When I am an old woman I shall wear purple With a red hat that doesn't go, and doesn't suit me, And I shall spend my pension on brandy and summer gloves And satin sandals, and say we've no money for butter. I shall sit down on the pavement when I am tired, And gobble up samples in shops and press alarm bells, And run my stick along the public railings, And make up for the sobriety of my youth. I shall go out in my slippers in the rain And pick the flowers in other people's gardens, And learn to spit.
You can wear terrible shirts and grow more fat, And eat three pounds of sausages at a go, Or only bread and pickle for a week, And hoard pens and pencils and beer mats and things in boxes. But now we must have clothes that keep us dry, And pay our rent and not swear in the street, And set a good example for the children. We will have friends to dinner and read the papers. But maybe I ought to practise a little now? So people who know me are not too shocked and surprised, When suddenly I am old and start to wear purple!
Nothing in life is to be feared, it is only to be understood. Now is the time to understand more, so that we may fear less. ~Marie Curie 附加一个名言分享,渣拍镇楼。
VULTURES are not exactly picky eaters. The carcasses on which they dine swiftly decompose, broken down by micro-organisms that excrete a range of nasty toxins. This makes decaying flesh a perilous source of food for most animals. Vultures, by contrast, either wait until their chosen corpse has decayed enough for them to peck through its often tough skin, or find a quicker way in via natural orifices. They frequently choose the fast-food route, inserting their head deep into the anus of large decomposing animals and exposing themselves to a mass of faeces-borne pathogens. Far from haute cuisine, then. Just how far is described by the first-ever genomic analysis of the micro-organisms found on and in the facial skin and large intestine of vultures, published this week inNature Communications. Warning: this is not lunchtime reading.
Among an average of 528 types of bacterium found on the heads of 50 turkey and black vultures were those that can cause botulism, gangrene, tetanus, septicaemia, blood clots and metastatic abscesses in other animals. And although these birds did not have it, another study foundBacillus anthracisin vulture faeces. It causes anthrax, except in vultures. Vultures clearly have strong stomachs, in every sense. With an acidity at least ten times that of a human’s, a vulture’s gut destroys a large amount of any potentially pathogenic bacteria that is ingested. Indeed, when the researchers analysed the contents of each bird’s large intestine, they could not detect some 85% of the micro-organisms they had found on its facial skin.
