[EX Q]: An Australian inventor has designed and built an environmentally friendly ferry that uses solar and wind power to transport people around Sydney Harbor. Robert Dane and his Solar Sailor were given the top prize at the Australian Design Awards recently. The Solar Sailor has been in use for six months. It uses four sources of energy for its power -- solar, wind, battery power with stored solar energy and a fuel generator in store all controlled by computers. The ferry can travel up to 7.5 knots on just wind and solar power. It's solar wings and fiberglass solar panels which not only take in sunlight and store it in batteries, but also act as sails. "We angle our solar panels to the sun in two planes , which increases the amount of energy we get from the sun by 40 percent," Dane says. "And also we can use that same structure to do another job, which is also the sail, and so these wing sails actually push the ferry forward just like a soft sail does." Computers check the sun and wind and angle the solar wings to take in the most sunlight. If there isn't much wind or it is a cloudy day, energy stored in the batteries runs the electric motor for up to five hours. "If the batteries are too low, then the computer turns the generator on so the boat is always able to meet a commercial schedule, or get from point A to point B no matter what," Dan explains. Dane got his idea for the Solar Sailor from a book on insects. He was amazed how insects use their wings to collect solar energy to warm themselves. "When I read that, I realized there was a good example in nature for what we were going to do, which was to use a solar wing to collect solar energy and also to sail," he says.

[EX Q]: Selenoproteins are proteins containing an uncommon amino acid selenocysteine (Sec). Sec is inserted by a specific translational machinery that recognizes a stem-loop structure, the SECIS element, at the 3' UTR of selenoprotein genes and recodes a UGA codon within the coding sequence. As UGA is normally a translational stop signal, selenoproteins are generally misannotated and designated tools have to be developed for this class of proteins. Here, we present two new computational methods for selenoprotein identification and analysis, which we provide publicly through the web servers at [Link] or [Link] SECISearch3 replaces its predecessor SECISearch as a tool for prediction of eukaryotic SECIS elements. Seblastian is a new method for selenoprotein gene detection that uses SECISearch3 and then predicts selenoprotein sequences encoded upstream of SECIS elements. Seblastian is able to both identify known selenoproteins and predict new selenoproteins. By applying these tools to diverse eukaryotic genomes, we provide a ranked list of newly predicted selenoproteins together with their annotated cysteine-containing homologues. An analysis of a representative candidate belonging to the AhpC family shows how the use of Sec in this protein evolved in bacterial and eukaryotic lineages.

[EX Q]: Who do you think was the most important woman of the past 100 years? Jane Addams (1860 - 1935) Addams helped the poor and worked for peace. She created shelters, education opportunities and services for people in need. In 1931, Addams became the first American woman to win the Nobel Peace Prize. Rachel Carson (1907 - 1964) Rachel Carson was born in the rural river town of Springdale, Pennsylvania in America. The popular 1962 book "Silent Spring" by Rachel Carson made people realize the dangers and the harmful effects of pollution on humans and on the world's lakes and oceans. Angela Merkel (1954 - ) In 2005, Germans chose Angela Merkel as their first woman head of the country. She had been a scientist in the past. As Germany's leader, she has had an effect on the whole world. Sandra Day O'Connor (1930 - ) When Sandra Day O'Connor finished her class at Stanford Law School, in 1952, she could not find work because she was a woman. However, she became the first woman to join the U.S. Supreme Court in 1981 after years of hard work. Margaret Thatcher (1925 - ) In 1979, Margaret Thatcher became Britain's first woman Prime Minister . She served until 1990, which made her the first British leader to serve three terms in a row. Because of her high standards and strong will, people called her Britain's Iron Lady. Marie Curie (1867-19245102534) Polish-born scientist Marie Curie discovered that some types of metal give off energy called radiation . Her research led to new medical treatments and arms. She received the Nobel Prize in Physics in 1903 and in Chemistry in 1911.
