The European Space Agency (ESA) is seeking volunteers who would be ready to take a part on three simulated missions to Mars.

The anticipated missions will be a joint effort from ESA and the Russian Federal Space Agency. Each crew will consist of six persons – two Europeans and four Russians. The ESA is looking for 2 crewmembers and two backups that must come from ESA member nations that participate in the ELIPS program.

The flight simulation should last between 105 to 520 days in a closed modules set of total space of 500 m³. The goal of the mission is to test the psychological stress of the long-distance travel. To make the experience as realistic as possible, the contact with the external world shall exist only via the radio with a time-delay of 40 minutes (simulating the time required for signals to travel between the Earth and Mars).

The first test of 105 days should start in middle of 2008 and the last one should start at the end 2008 or the beginning of 2009.

Interested persons can apply via an application form published on the ESA website.

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!

In New South Wales today, thousands of people joined a protest including 15 Labor Members of Parliament about the State Government’s plans to privatise the electricity industry.

The MPs included Paul Gibson, Upper House president Peter Primrose, and former MPs Kerry Hickey and Grant McBride.

Mr Gibson was reported as saying, “I’m a member of the Australian Labor Party and I’m sticking to the Labor platform and policy.”

The Government seems to have ignored the positions of the protesters, with Premier Morris Iemma expressing to the first sitting of Parliament for 2008 that his Government’s plans would proceed.

Related instances in Tamworth occurred, when workers in the Electricity Trade Union walked off the job.

A group of volcanologists from the UK and USA have traveled to North Korea to assist them with conducting scientific investigations and installing equipment near the volcano Mount Paektu.

Wikinews interviewed Dr. Robert Kelly of Pusan National University (PNU) in South Korea, who specialises in security and diplomacy and Dr. Jim Gill from the University of California who has visited the Chinese side of Mount Paektu.

((Wikinews)) Given that the UK, USA have strained political relations with North Korea, what is the purpose of these scientists working together?

Dr. Robert Kelly: Mt Paektu erupted massively about 1100 years ago and has been dormant since. Recently there has been seismic activity, and should it explode again, it could be gigantic — and devastating. It is everyone’s interest in East Asia to know about such a possibility, so this kind of cooperation can be above politics. But it is also always good to engage North Korea to try to draw them out. Such engagement can occur in nonpolitical, technical areas like this most easily.

((WN)) Does North Korea understand that it needs the specialism of British and American scientists to plan for when the volcano erupts?

RK: It does. North Korea does actually engage in various track II programming, including student and administrative exchanges. This is not well-known due to the nuclear issue however. The North Korean government is aware of its technological backwardness, and they often dangle concessions to other states in exchange for tech transfers like this.

((WN)) The North Korea underground nuclear test site is very close to the volcano, do you think this affected North–South Korean relations?

RK: Not very much. It does upset South Koreans somewhat, because Mt. Paektu is actually [a] national landmark. It is the mythological birthplace of the Korean people. And there is some scientific concern that major seismic activity could impact nuclear facilities.

((WN)) Do you think that the field work being carried out by the scientists, being near a militarised border is very difficult?

RK: No, because it is in the interest of all local parties — NK, Chinese, even Russian — that Mt. Paektu is properly monitored. Indeed, I could imagine that, behind the scenes, the Chinese pushed North Korea toward this cooperation, as this is somewhat unusual for NK.

((WN)) May the North Koreans be wary and suspicious of their British and American counterparts, given the secretiveness of the state?

RK: Absolutely. I have been to NK, and I can say positively that the scientists will be monitored and accompanied at all times they are away from their hotels. They will also be isolated from the NK wider population. They will only interact with specially chosen minders who speak excellent English and have proven their loyalty to the state. And there will be security personnel with them at all times outside their hotels too.

((WN)) Do you think that Western scientists collaborating together with the North Koreans could set as an example of political things to see in the future?

RK: Not really. I hope so, but North Korean^[sic] has a tendency to pretend to open itself, and then to re-close after it gets what it wants. All sorts of interaction with North Korea gets hyped as ‘a new beginning’ or a ‘historic opening,’ only to come to naught. That does not mean it could not happen, just that I am skeptical. Instead, NK is likely to continue to interact when and where it has certain specific needs, as in this case. And that interaction will be tightly monitored. Fifteen years [ago], at the start of the Sunshine Policy by SK, there was hope that increased interaction would grow organically and slowly open up NK. That was the spirit behind the Kaesong industrial zone. But in fact, the North Koreans tightly controlled Kaesong to capture its gains and limit spillovers. I imagine the same will happen here.

((WN)) Do natural hazards pay attention to international political differences?

Dr. Jim Gill: Of course not.

((WN)) Is there a high risk and increased seismic activity in relation to Mount Paektu?

JG: Not currently. There was unrest at the volcano during 2002–05 but it has returned to normalcy.

((WN)) Would an eruption of Mount Paektu have consequences for multiple countries?

JG: Yes. The most likely widespread consequence will be an interuption of air traffic between North Asia and North America and Europe. More locally, the tourist industry on the Chinese side of the border will be very impacted. Most ash fall will be in the DPRK.

For perspective, there was an extremely large eruption of the volcano at about 940 AD — one of the largest historical eruptions anywhere on Earth. It is uncertain how often it has erupted since, and how large the eruptions were, but nothing has been big enough to cause serious problems scores of kilometers away. So yes there is risk — it is large mountain with a long history of eruptions — but nothing indicates a high level of concern now.

At about 5.00 a.m. today local time (2100 yesterday UTC), police in Hong Kong moved to clear obstacles to traffic at the intersection of Argyle Street and Nathan Road in Mong Kok, Hong Kong. For weeks the normally busy crossroads has been occupied by pro-democracy protesters and closed to traffic.

Police in riot gear cordoned off the roads and alleyways that surround the intersection, before moving in with trucks equipped with mechanical grabs to clear the roads of makeshift barricades. Also removed were tents, personal belongings, bedding and any other material protesters couldn’t retrieve in time. Many of the protesters were asleep when the police action began.

The police said they were acting to reopen the roads to traffic, not to forcibly clear the site of protesters, however the protestors were also urged to peaceably leave the site.

The police action effectively dispersed the majority of the protesters from the site. Protesters were moved onto the sidewalk by the police; when they could no longer be accommodated on the sidewalk they spilled into the alleyways, and down Nathan Road towards Tsim Sha Tsui. Once they had crossed the police cordon they were not allowed to return to the intersection. A small number of protesters remained on the pavements surrounding the intersection.

Protesters interviewed by local television station TVB said they felt the police had misled them; some said they would join protesters on Hong Kong Island, while others said they wished to remain in Mong Kok to maintain the pressure on the government.

The Mong Kok site is one of the three main protest sites of the wider 2014 Hong Kong protests. Protesters have been demonstrating in a bid for the right by the public at large to have a role in the nomination of candidates to stand for the post of Chief Executive of the territory.
