Founded in 1999, and the first-ever 24 hour ultra-marathon race in Taiwan, the 7th Soochow International 24H Ultra-Marathon, took place on November 24-25, 2007. Even though the race has been suspended in the past, in 2000 and 2006, due to poor conditions on the track field, several world-class runners participated in the 2007 race.

The United Arab Emirates (UAE) has started construction of its so called ‘green city‘ which will be named Masdar City. It is a city which is designed to have no carbon emissions, cars, or waste. It will cost $22 billion (£11 billion) and take eight years to make. It will be able to hold a population of 50,000 people and 1,500 businesses. The city will cover 1,483 acres (6.00 km²).

The city was designed by Foster and Partners, a British company.

“No one has ever built a zero-carbon city before. Nor one producing zero waste or fully powered by renewable energy. Masdar City will accomplish all three,” said Sultan Al Jaber.

The city will have a personal electrical power supply mainly from two renewable energy sources: wind turbines and solar panels. Water will be provided through a solar-powered desalination plant and air conditioning will be provided naturally from wind towers.

It is planned to save more than $2 billion in oil over the next 25 years along with creating more than 70 000 jobs.

The immense project will be supported by a company created for it called ‘Masdar Initiative’, which will develop and commercialise clean energy technologies. It will also be supported by the WWF, a global conservation charity, and it is hoped that international joint ventures will bring in more money.

Some people fear that Masdar will become a domain for the luxury development of the rich, because the city is located by Abu Dhabi and Abu Dhabi International Airport.

Dr Al Jaber said, “We are often asked why we are setting our goal so high. Our answer is because someone must… Someone must push the envelope to create the solution that we, as a global community, so urgently require.”

In May, periodical cicadas with 17 years life cycle emerged on the East Coast of the USA after underground development as juveniles since 1996. Researchers and scientists worked to map and study the rare wave, and the locals prepared for the noisy event. First recorded in 1666, the Magicicada septendecim species recently emerged in 1979, 1996, this year, with a next wave due in 2030.

This week, Wikinews interviewed Chris Simon, an ecology and evolutionary biologist at University of Connecticut, about the cicadas.

((Wikinews)) What caused your initial interest in periodical cicadas?

Chris Simon: As an undergraduate student, I was interested in the formation of species so when I went to graduate school I looked for a study organism that was likely to be in the process of forming new species. I chose periodical cicadas because they are broken up into reproductively isolated broods (or year classes). Reproductive isolation leads to speciation so I planned to study biochemical differences among the broods.

((WN)) You study the emergence of the periodical cicadas. What do you study? What observations are you making?

CS: We record exactly where each cicada population emerges (using GPS automated mapping and crowd sourcing). We record the presence or absence of each of the three morphologically distinct species groups of periodical cicadas (Decim group, Cassini group, and Decula group). We collect specimens for DNA analysis. We look for cicadas coming up one and four years early and late. We dig up cicada nymphs and monitor their growth rates.

((WN)) What equipment do you use?

CS: Nets, shovels, automated GPS recorders, cameras, laptop computers, automated DNA sequencers.

((WN)) Do you study the periodical cicadas with anyone else? What is their role?

CS: Yes, there are a large number of people studying periodical cicadas in my lab and in other labs. My lab is made up of Research Scientists, Postdoctoral Researchers, a technician, graduate students, and undergraduates. Research Scientist John Cooley is the leader of the GPS mapping project; he invented the automated GPS recorder; he built our crowd-sourcing website, and he is instrumental in public outreach. Postdoctoral research David Marshall also participates in the mapping project and leads the part of the research related to the mapping of stragglers. John and Dave and Technician Kathy Hill all study periodical cicada mating behavior and conduct mating and hybridization experiments. One of my graduate students Beth Wade has participated in the nymph collections and will soon start genetic work involving genome wide association mapping designed to locate genes related to life cycle. My graduate student Russ Meister is studying the genes of the bacterial endosymbionts of cicadas. My current undergraduate honors student Erin Dwyer is also studying the development of Magicicada nymphs and is helping to design a lab exercise for college students around the eastern US to do the same. Many of my past undergraduate students have studied the biochemical genetics and development of periodical cicadas. See the Simon Lab website.

CS: We are collaborating with Teiji Sota at the University Kyoto and Jin Yoshimura at Shizuoka University in Japan. They are studying the phylogeography of Magicicada. We are collaborating with John McCutcheon of the University of Montana who is studying the endosymbiont genomes.

CS: We are also collaborating with ecologists Rick Karban and Louie Yang, both professors at UC Davis who have an interest in cicada population dynamics and nutrient cycling in the ecosystem.

((WN)) You studied the periodical cicadas in 1979 and 1996 too. What changes with time?

CS: I have studied periodical cicadas since I was a student back in 1974. What changes with time is increased human development constantly shrinking the patch size of cicada populations.

((WN)) What are your thoughts on the long life span of the periodical cicadas? Why could it be so? What advantages and what disadvantages does it have?

CS: Most or all cicadas have long life cycles compared to your typical annual insect. Examples have been found of two-year to 9-year cycles in different species. Periodical cicadas evolved an even-longer life cycle and I think that part of this relates to the evolution of their synchronized life cycles and peculiar safety-in-numbers strategy for survival. To become synchronized, periodical cicadas had to evolve an exact length life cycle and all adults would have to appear in the same year. Because the nymphs grow at different rates underground, a longer life cycle and a way of counting years must have evolved so that the individuals that get to the last nymphal (underground juvenile) stage first would wait long enough for all other individuals in the population to become ready to emerge.

((WN)) News reports mention this is ‘Brood II’ of the periodical cicadas. What are the distinctive features of this specific species and what is its full scientific name?

CS: The same species exist in multiple broods. No species is restricted to Brood II. The three species present in Brood II are: Magicicada septendecim, M. cassini, and M. septendecula. These same three species are found in every 17-year brood (except the farthest north which only has M. septendecim).

((WN)) At what depth do the cicadas juveniles live underground?

CS: Most live within the top foot of soil but some have been found deeper. We do not know if they go deeper in winter. We need to do much more digging to understand the nymphs.

((WN)) How do people prepare for the cicada emergence?

CS: Of course various people prepare in different ways. Ideally, everyone prepares by studying information available on the web (especially on our websites Magicicada Central and Magicicada.org).

((WN)) Do cicadas affect transport in the local area?

CS: No, not really. Occasionally individuals can be seeing flying across highways and sometimes they smash into cars.

((WN)) Do cicadas usually stay outside or do they also invade houses too?

CS: They stay outside. One might accidentally fly in through an open window but that would be rare.

((WN)) What do the cicadas eat?

CS: Cicadas suck xylem fluid (the watery fluid coming up from the roots of plants) in deciduous forest trees and herbs. Essential amino acids in the cicada diet are supplied by their bacterial endosymbionts. There are two species of endosymbionts. One makes 8 essential amino acids and one makes two essential amino acids.

((WN)) Do cicadas damage crops or city vegetation? What damage?

CS: Cicadas do not chew leave so they do not damage crops like other insects. They can inflict some damage by their egg laying. Cicadas lay eggs in pencil-sized tree branches. If there are not enough branches available, too many female cicadas may lay eggs in a single branch weakening it and making it susceptible to breakage by wind. This can sometimes cause damage in fruit orchards. If the branches break, the eggs die so this behavior is selected against by natural selection.

((WN)) Thank you.

CS: You’re welcome. I am happy to have this opportunity to communicate with your readers!

Parts of a body belonging to a child have been discovered at the Haut de la Garenne in Saint Martin, Jersey, a United Kingdom Crown dependency off the coast of Normandy, France.

The Victorian building, which was originally built as a children’s care home and is now a youth hostel, has been under investigation recently as part of an inquiry into child abuse which occurred during the 1960s. The investigation has now been refocused with the aim to excavate further the grounds of the building, under the command of a specialist team from the UK who will use ground scanners and sniffer dogs to detect any other possible remains.

The body is believed to date from the early 1980s though further information about the identity of the child has not yet been released. The remains were found buried underneath a concrete floor inside the building. Today, the Guardian newspaper revealed that there are fears of a possible six further bodies buried on the site.

“There could be six, but it could be higher than that,” according to lead investigator Lenny Harper, who further said, “Allegations range from physical assaults right through to rape. It is difficult to envisage more horrific crimes than some of those that are alleged to have been carried out here.”

A helpline set up to find more information about alleged child abuse at the Haut de la Garenne and Jersey Sea Scouts has garnered a total of 140 contacts, made up of those claiming to be witnesses or victims to the crimes. The information gathered from the telephone inquiry triggered the search of the grounds.

On October 14, 2008, Canadians will be heading to the polls for the federal election. New Democratic Party candidate Katy Austin is standing for election in the riding of Simcoe—Grey. Born in St. Catherines and raised in Barrie, Austin has a Bachelor of Physical and Health Education from the University of Windsor. Teaching in various Ontario schools, she has been active in the Simcoe NDP riding association since 1975. Austin rode her bike, solo, from Victoria, British Columbia to Elmvale, Ontario (a total of 4 500 km) in 40 days during the summer of 1996, camping along the way.

Wikinews contacted Katy Austin, to talk about the issues facing Canadians, and what they and their party would do to address them. Wikinews is in the process of contacting every candidate, in every riding across the country, no matter their political stripe. All interviews are conducted over e-mail, and interviews are published unedited, allowing candidates to impart their full message to our readers, uninterrupted.

The riding is currently held by Helena Guergis (Conservative), the Secretary of State for Foreign Affairs, International Trade and Sport. Also challenging Guergis are Peter Ellis (Green), Andrea Matrosovs (Liberal), Caley McKibbin (Libertarian), and Peter Vander Zaag (Christian Heritage).
