  Australian scientists are trying to give kangaroo-style stomachs to cattle and sheep in a bid to cut the emission of greenhouse gases blamed for global warming.

  Thanks to special bacteria in their stomachs, kangaroo farts contain no methane(甲烷)and scientists want to transfer that bacteria to cattle and sheep who emit large quantities of the harmful gas.

  While the usual image of greenhouse gas pollution is a billowing smokestack pushing out carbon dioxide, livestock passing wind contribute a surprisingly high percentage of total emissions in some countries.

  "Fourteen percent of emissions from all sources in Australia is from enteric methane from cattle and sheep," said Athol Klieve, a senior research scientist with the Queensland state government.

  "And if you look at another country such as New Zealand, which has got a much higher agricultural base, they're actually up around 50 percent," he said.

  Researchers say the bacteria also makes the digestive process much more efficient and could potentially save millions of dollars in feed costs for farmers.

  But it will take researchers at least three years to isolate the bacteria, before they can even start to develop a way of transferring it to cattle and sheep.

  Another group of scientists, meanwhile, has suggested Australians should farm fewer cattle and sheep and just eat more kangaroos.

  The idea is controversial(爭(zhēng)議), but about 20 percent of health conscious Australians are believed to eat the national symbol already.

  "It's low in fat, it's got high protein levels and it's very clean in the sense that basically it's the ultimate free range animal(散養(yǎng)動(dòng)物)," said Peter Ampt of the University of New South Wales's institute of environmental studies.

  Not even Dan Brown and his Da Vinci code-breakers(密碼破譯者)dared deal with the mystery of Mona Lisa’s smile.But Nicu Sebe, a computer expert at the University of Amsterdam, the Netherlands, did.He used ‘emotion recognition’ software to process the famous painting and found Mona Lisa happy(83 per cent)and slightly disgusted(厭煩的)(9 per cent).

  Faces show emotions.Psychology, computer science, and engineering researchers are joining forces to teach machines to read expressions.If they succeed, your computer may one day“read”your mood.Machines equipped with emotional skills could also be used in teaching, gaming, mind-reading, etc.

  “Mind Reader”, a system developed by Rosalind Picard at MIT(the Massachusetts Institute of Technology)in the US, uses input from a video camera to do real-time analysis of facial expressions.It reports on whether you seem“interested” or“agreeable”or if you’re“confused”.The system can help people recognize others’ emotions.Picard says this means we could teach a machine to be as sensitive as a human.In fact, a machine can be even smarter than people since it can tell if a person is lying or just“performing”by analyzing one’s facial movements.

  Jeffrey Cohn, a psychologist at the University of Pittsburgh, uses the Facial Action Coding System to recognize human emotions.The system sorts more than 40 action units(AUS)of the face to tell people’s real emotions.He studied a videotape of a criminal who said to be sad about the murder of several family members and tried to pin the blame on someone else.But Cohn saw no real sadness in the woman’s face.

  Sadness is a group of AUS that is difficult to do at the same time.You have to pull down the corners of your lips while bringing your eyebrows together and raising them.What the woman did was raise her cheeks to make a lip curl(撇嘴).Her brows stayed smooth.
