Mammals recognize humans, we know, but so does the crow

New Scientist (http://www.newscientist.com, 15 September 2012) reported that wild crows remember human faces in the same way that mammals do. We’ve known for a long time that mammals, such as marsupials, rodents, primates, whales, elephants, horses, and dogs, recognize and respond to people. Now scientists maintain that crows can too.

Scientists at the University of Washington in Seattle, America, have shown that crows can distinguish human faces and remember how they were treated by humans. Scientists wore latex masks as they captured 12 wild American crows (Corvus brachyrhynchos). The crows associated the captor’s masks with this traumatic experience. While in captivity, the crows were fed and cared for by people wearing a different mask from those who captured them.

After four weeks, the researchers scanned images of the captured crows’ brains to monitor their brain patterns. They tested the crow’s brain patterns whenever they were with people with “capture” masks and with “feeding” masks.

People feeding the crows with “feeder masks” led to brain activity in the crows that were involved with motivation and reward. When the crows were faced with people in “capture” masks, their brains registered fear – leading scientists to believe that the crows remembered the faces of their captors. Scientists also maintained that the crows did not mind humans being in their habitat, but they needed to keep a close eye on what humans did – and how they reacted with the crows.

Flaws in the Glass, a self-portrait by Patrick White: book review

The manuscript, Flaws in the Glass (1981), is Patrick Victor Martindale White’s autobiography. White, born in 1912 in England, migrated to Sydney, Australia, when he was six months old. For three years, at the age of 20, he studied French and German literature at King’s College at the University of Cambridge in England. Throughout his life, he published 12 novels. In 1957 he won the inaugural Miles Franklin Literary Award for Voss, published in 1956. In 1961, Riders in the Chariot became a best-seller, winning the Miles Franklin Literary Award. In 1973, he was the first Australian author to be awarded the Nobel Prize for Literature for The Eye of the Storm, despite many critics describing his works as ‘un-Australian’ and himself as ‘Australia’s most unreadable novelist.’ In 1979, The Twyborn Affair was short-listed for the Booker Prize, but he withdrew it from the competition to give younger writers the opportunity to win the award.

Sister cities discussed: Canberra and Islamabad

Two months ago, in March 2015, Australia and Pakistan agreed to explore ways to deepen ties. The relationship between Australia and Pakistan has been strong for decades, and the two countries continue to keep dialogues open. The annual bilateral discussions were held in Australia in March to continue engagements on a wide range of matters of mutual interest. The Pakistan delegation discussed points of interest will include sports, agriculture, economic growth, trade, border protection, business, and education. The possible twinning of the cities of Canberra, the capital of Australia, and Islamabad, the capital of Pakistan, were also on the agenda (i.e. called twin towns or sister cities). Sister City relationships are twinning arrangements that build friendships as well as government, business, culture, and community linkages. Canberra currently has international Sister City relationships with Beijing in China and Nara in Japan. One example of existing
