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!

Rico Daniels is a British TV presenter living in France who is known for his two television series — The Salvager — whilst he still lived in the UK and then Le Salvager after he moved to France. Rico has been in a variety of jobs but his passion is now his profession – he turns unwanted ‘junk’ into unusual pieces of furniture. Rico’s creations and the methods used to fabricate them are the subject of the Salvager shows.

Rico spoke to Wikinews in January about his inspiration and early life, future plans, other hobbies and more. Read on for the full exclusive interview, published for the first time:

Despite the hopes of many University of Wisconsin-Madison (UW) students, The Onion was not named after their student center. “People always ask questions about where the name The Onion came from,” said President Sean Mills in an interview with David Shankbone, “and when I recently asked Tim Keck, who was one of the founders, he told me the name—I’ve never heard this story about ‘see you at the un-yun’—he said it was literally that his Uncle said he should call it The Onion when he saw him and Chris Johnson eating an onion sandwich. They had literally just cut up the onion and put it on bread.” According to Editorial Manager Chet Clem, their food budget was so low when they started the paper that they were down to white bread and onions.

Long before The Daily Show and The Colbert Report, Heck and Johnson envisioned a publication that would parody the news—and news reporting—when they were students at UW in 1988. Since its inception, The Onion has become a veritable news parody empire, with a print edition, a website that drew 5,000,000 unique visitors in the month of October, personal ads, a 24 hour news network, podcasts, and a recently launched world atlas called Our Dumb World. Al Gore and General Tommy Franks casually rattle off their favorite headlines (Gore’s was when The Onion reported he and Tipper were having the best sex of their lives after his 2000 Electoral College defeat). Many of their writers have gone on to wield great influence on Jon Stewart and Stephen Colbert‘s news parody shows.

And we are sorry to break the news to all you amateur headline writers: your submissions do not even get read.

Below is David Shankbone’s interview with Chet Clem and Sean Mills about the news empire that has become The Onion.

Monday saw the latest edition of the vetted version of Wikipedia, which is aimed at educational use, go quietly online. The extensively revised version covers over five thousand topics, targeting the eight to seventeen years age group. Partnerships with the Shuttleworth Foundation and the Hole in the Wall project will see it distributed in South Africa and India as well as copies being available globally via the offices of SOS Children UK’s umbrella organisation, SOS Kinderdorf worldwide.

First launched in 2006 as a 4,000 article edition, the extract of Wikipedia has employed hi-tech distribution methods, as well as offering a website version which has steadily climbed up in ranking to above other reviewed Wikipedia rivals and copies; the 2007 version was available on the BitTorrent peer to peer network to keep distribution costs down and was equivalent to a fifteen-volume printed encyclopedia. Monday’s release is compared to a twenty-volume print edition.

Key to the process for selecting articles is the English National Curriculum and similar educational standards around the world. The initial vision was to bring this wealth of knowledge to schools where access to the Internet was poor or unavailable, but copies of Wikipedia for Schools can be found on many first world school intranets and web servers. Among the compelling reasons to adopt the project are the vetting and additional study materials which overcome the oft-publicised concerns many educators have with the million article plus Wikipedia that anyone can edit.

In today’s press release announcing the launch, Wikimedia Foundation Executive Director Sue Gardner expressed delight at seeing the project bring out a new version, “Our goal is to make Wikipedia accessible to as many people as possible around the world, and SOS Children is a great partner that helps us make that happen. Wikipedia is released under a free content license so that individuals and institutions can easily adapt, reuse and customize its content: we encourage others, like SOS Children, to do exactly that.”

Running 192 schools in the developing world, SOS Children sees Wikipedia for Schools as a key piece in fulfilling the educational aspect of their mission. SOS Children’s Chairwoman, Mary Cockcroft gave us an introduction and, a Wikipedia administrator himself, the charity’s CEO Andrew Cates spoke to Wikinews at length about the project.

You are part of SOS-Kinderdorf International, can you explain a little about how this works in terms of distributing funds raised in the UK and involving UK citizens in work outside the country?

Mary Cockcroft: SOS Children[‘s Villages] is a “club” of member charities in 130 countries helping orphans and vulnerable children. The club elects SOS-Kinderdorf International as secretary. SOS is a large organisation whose members in aggregate turned over $1bn in 2007, and whose projects include owning and running 192 schools and family-based care for 70,000 children. However much of these funds are raised locally, with for example the member charities in each of India, Pakistan and South Africa raise considerably more funds in their own country than SOS UK does from the UK. Nonetheless SOS Children UK principally raises funds to finance projects in the developing world, and has only financially small projects in the UK (such as the Schools Wikipedia, which is very low cost because of extensive use of volunteers). This year we expect about 80% of our UK income will leave the UK for overseas SOS associations, and some of the remaining 20% will pay for project oversight. We do not spend money in the UK on Direct Mail or TV advertising. Our UK office is involved in overseeing projects we finance and a small number of high-skilled volunteers from the UK help overseas. However around 98% of SOS staff worldwide are local nationals, as are most volunteers.

((WN)) How much work does the UK charity actually carry out within the home country? Are there failings within the government system for orphans and other needy children that you feel obliged to remedy?

MC: We are deeply unhappy about the situation of children in out-of-home care in the UK. However our care model of 168 hour-a-week resident mothers does not fit with the UK philosophy for children without parental care. Internationally SOS always has a policy of sharing best practice and we are working to improve understanding of our way of working, which appears to us to have far better outcomes than the existing one in the UK. Ultimately though the legal responsibility for these children lies with government and we cannot remedy anything without their invitation.

((WN)) Who first came up with the idea of doing a vetted Wikipedia extract? What was the impetus? Was it more for the developing world than first world?

Andrew Cates: I honestly cannot remember who first suggested it, but it came from somewhere in the Wikipedia community rather than from the charity. The original product was very much pitched at the developing world where the Internet is only available if at all over an expensive phone line. I worked in West Africa 1993-1996 and I know well at how thirsty for knowledge people are and how ingenious they will be in overcoming technical obstacles if the need for infrastructure is removed.

((WN)) In reading past year’s announcements there’s some pride in the project being picked up and used in the first world, was this expected or a pleasant surprise?

AC: It was a pleasant surprise. I don’t think we had realised what the barriers schools faced in using the main Wikipedia were. It isn’t just pupils posting material about teachers or meeting strangers: the “Random Article” button on every page could potentially deliver an article on hardcore porn. We had already started when discussion broke on banning Wikipedia from classrooms and I am sure we benefited from it.

((WN)) Can you give an outline of the selection and vetting process? Is it primarily Wikipedians working on this, or are people from the educational establishment brought in?

AC: It was a long and painful process, even with a really good database system. Articles were taken into the proposal funnel from three main sources: direct proposals for inclusion from Wikipedians, lists which came from the Release Version team and proposals drawn up from working through National Curriculum subjects by SOS volunteers. In a few cases where we felt articles were missing we asked the community to write them (e.g. Portal:Early Modern Britain, which is a curriculum subject, was kindly written just for us): These “proposals” were then looked at by mainly SOS volunteers (some onwiki, some offline). Our offices are in the middle of Cambridge and we get high quality volunteers, who skim read each article and then compared two versions from the article history by credible WP editors a significant period apart (this picks up most graffiti vandalism which runs at about 3% of articles). Once they had identified a “best” version they marked any sections or text strings for deletion (sections which were just a list of links to other articles not included, empty sections, sex scandals etc). A substantial sample of each volunteers work was then doubled checked for quality by one of two office staff (of whom I was one). We then have a script which does some automated removals and clean ups. Once we had a selection we posted it to relevant wikiprojects and a few “experts” and got any extra steers.

((WN)) Will you be making use of BitTorrent for distribution again this year? Was it a success in 2007?

AC: BitTorrent was a bit disappointing in that it got us the only substantial criticisms we received online. A lot of people find it too much effort to use. However for the period we offered a straight http: download we had huge problems with spiders eating vast bandwidth (the file is 3.5G: a few thousand rogue spider downloads and it starts to hurt). As per last year therefore our main two channels will be free download by BitTorrent and mailing the DVDs free all over the world. At a pinch we will (as before) put straight copies up for individuals who cannot get it any other way, and we have some copies on memory sticks for on distributors.

((WN)) Is it your opinion that the UK Government should be encouraging the adoption of projects like this as mainstream educational resources?

AC: Clearly yes. We have had a very enthusiastic reaction from schools and the teaching community. We think every school should have an intranet copy. We expect the Government to catch on in a few years. That is not to say that Wikipedia is as good as resources developed by teachers for teachers such as lesson plans etc. but it is a fantastic resource.

((WN)) You’re a Wikipedia administrator, all too often a thankless task. What prompted you to get involved in the first place? What are the most notable highs and lows of your involvement with the project?

AC: Funnily the thing I have found most amazing about Wikipedia is not widely discussed, which is the effect of Wikipedia policies on new editors. I have seen countless extreme POV new editors, who come in and try to get their opinions included slowly learn not only that there are other opinions to consider but that elements of their own opinion which are not well founded. Watching someone arrive often (on pages on religions for example) full of condemnation for others, gradually become understanding and diplomatic is one of the biggest buzzes there is. The downside though is where correcting things which are wrong is too painfully slow because you need to find sources. I was a post-doc at Cambridge University in combustion and I know the article on Bunsen burners has several really significant errors concerning the flame structure and flow structure. But sadly I cannot correct it because I am still looking around for a reliable source.

((WN)) Do you believe schools should encourage students to get involved contributing to the editable version of Wikipedia? Does SOS Children encourage those who are multilingual to work on non-English versions?

AC: I think older students have a lot to learn from becoming involved in editing Wikipedia.

((WN)) To close, is there anything you’d like to add to encourage use of Wikipedia for Schools, or to persuade educators to gain a better understanding of Wikipedia?

AC: I would encourage people to feed back to the project online or via the charity. The Wikipedia community set out to help educate the world and are broadly incredibly well motivated to help. As soon as we understand what can be done to improve things people are already on the task.

((WN)) Thank you for your time.

Minas, one of the largest states of Brazil, has stopped the sale of the Toyota Corolla over safety concerns.

The move was made after nine Corolla customers reported that their cars automatically accelerated. The state public prosecutor’s office said in an online statement on Tuesday that the problem is blamed on accelerator pedals sticking underneath floor mats. Local government said the issue was “putting in danger the lives of occupants”.

According to the prosecutor’s office, sales of Corollas may resume when Toyota alters the floormats in its current models. Toyota has recalled over eight million vehicles worldwide due to acceleration problems.

U.S. Representative Randy “Duke” Cunningham (R–CA) pled guilty today to conspiring to take bribes in exchange for using his influence as a member of the House Appropriations Committee to help a defense contractor get business. In total he pled guilty to one count of income tax evasion and four counts of conspiracy, namely mail fraud, wire fraud, bribery of public official and accepting bribes. U.S. District judge Larry A. Burns scheduled Cunnigham to be sentenced on February 27. He is facing up to 10 years in prison and nearly $500,000 in fines, as well as forfeiture of unspecified amounts of cash and property.

In the court hearing, Cunningham admitted to accepting “bribes in exchange for performance of official duties” between “the year 2000 and June of 2005”, taking “both cash payments and payments in kind” and following up by “trying to influence the Defense Department”.

The federal investigation against Cunningham was triggered by his sale of his California residence to defense contractor Mitchell Wade in late 2003. However, Wade never moved in and sold the house at a $700,000 loss three quarters of a year later. At the same time Wade’s company MZM won tens of millions of dollars in defense contracts. Subsequent investigations discovered more questionable business transactions, including interactions with the defense contractor ADCS. In his plea agreement he testified that, among other charges, he “demanded, sought and received at least $2.4 million in illicit payments and benefits from his co-conspirators in various forms, including cash, checks, meals, travel, lodging, furnishings, antiques, rugs, yacht club fees, boat repairs and improvements, moving expenses, cars and boats.”

Cunningham announced his resignation after the hearing. In a written statement released by his law firm O’Melveny & Myers LLP he declared “The truth is — I broke the law, concealed my conduct, and disgraced my high office. I know that I will forfeit my freedom, my reputation, my worldly possessions, and most importantly, the trust of my friends and family.”

At 3:45 p.m. Tuesday, Eastern Time (2045 UTC), the SpaceX Falcon Heavy rocket launched from Kennedy Space Center in Florida, United States. Its cargo: a US$100,000 Tesla sportscar, the personal property of SpaceX CEO Elon Musk, which he hopes will soon be in its own orbit around the Sun. This is the most powerful rocket since the Saturn V of Project Apollo was retired in 1970. The rocket is meant to follow a course called a Hohmann transfer orbit.

“It’ll be a really huge downer if it blows up,” Musk told the press the day before the launch, but went on to say, “If something goes wrong, hopefully it goes wrong far into the mission so we at least learn as much as possible along the way. I would consider it a win if it just clears the pad and doesn’t blow the pad to smithereens. That’s four million pounds of TNT equivalent so there’s probably not going to be much left if that thing lets loose on the pad.” The car was equipped with a fully space-suited dummy, cameras to monitor its trip into space, a copy of Douglas Adams’ Hitchhiker’s Guide to the Galaxy, and a radio blasting Space Oddity by David Bowie.

The Falcon Heavy has a total of 27 engines and stands 230 feet (70.1 m) tall. According to SpaceX, the Falcon Heavy uses three boosters, the same kind as the company’s smaller cargo rockets. After the rocket exited the Earth’s atmosphere, two of these boosters detached from the main body of the rocket and, in a first for space technology, were successfully guided back down to the landing pad about ten minutes after launch. The third was to have landed on a drone ship, but missed by around 100 yards (about 90 meters) and hit the ocean “at around 200 miles per hour,” according to Musk. The reusability of the boosters makes an enormous difference in the cost of the launch.

Even the relatively heavy-hauling U.S. Space Shuttle program, which was closed in 2013, did not rely on rockets as powerful as those used in Project Apollo, the program in which NASA, the U.S. Government space agency, sent manned missions to the Moon in the 1960’s and 70’s. Most recent space projects have focused on smaller, lighter machinery, such as Scaled Composites’ SpaceShipOne in 2004, which reached space after being carried part of the way by a carrier jet instead of launching from the ground. As of last week, the most powerful rocket in use was the Delta IV, operated by the United Space Alliance. It costs about US$435 million per launch, while SpaceX says the Falcon Heavy will cost US$90 million per launch.

NASA is also working on a heavy-duty rocket, the Space Launch System, but there have been delays.
