I am currently in the ABRG in the first year of my D Phil. I am studying the orientation of homing pigeons using newly miniaturized GPS receivers. GPS stands for Global Positioning System and the receivers make use of satellite signals to give readings of longitude, latitude and altitude. The readings are precise to � 5m and are made every second so tracks of very high spatial and temporal acuity can be recorded. The tracks can be superimposed on to topographical maps to illustrate precisely where ea pigeon has flown. Using this technology, and experimental techniques such as clock-shifting, I aim to investigate the use of visual landmarks and to look into how birds correct their routes when experimentally manipulated to fly in the wrong direction."

At USDA, the Mouse Is in the House

(washingtonpost.com) : "Employees at the Department of Agriculture's main cafeteria were just sitting down to lunch on Friday when security guards ordered everyone in the huge eatery to leave. Al Qaeda? Bomb scare? No. Mouse droppings. The D.C. Department of Health closed the cafeteria for failing to pass inspection. Yes, the USDA, home to the Animal and Plant Health Inspection Service, the meat and poultry inspectors -- the agency that is part of the federal system for protecting the nation's food supply, was in violation of the D.C. Health Code.

Artist turns animals into everyday objects

Ananova - A Chilean artist is making a name for herself with an exhibition in which stuffed animals are transformed into household objects. Artworks on display include a chick turned into a lamp, and 'sheep bag' - a lamb carcass fitted with handles. Artist Caterina Purdy says her exhibition at the Experimental Arts Centre in Santiago is intended to be humorous but also makes a serious point. She told Las Ultimas Noticias online: 'It is possible to see my work as something scary, but I find it beautiful. 'There is also irony and humour in my objects as well as a criticism of the way animals are treated by society.'"

BW Online | March 1, 2004 | Software : "As Stephen and Deepa emerge this summer from graduate school -- one in Pittsburgh, the other in Bombay -- they'll find that their decisions of a half-decade ago placed their dreams on a collision course. The Internet links that were being pieced together at the turn of the century now provide broadband connections between multinational companies and brainy programmers the world over. For Deepa and tens of thousands of other Indian students, the globalization of technology offers the promise of power and riches in a blossoming local tech industry. But for Stephen and his classmates in the U.S., the sudden need to compete with workers across the world ushers in an era of uncertainty. Will good jobs be waiting for them when they graduate? 'I might have been better served getting an MBA,' Stephen says."
