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!

Australian researchers say they have scientifically proven that stress causes sickness. The Garvan Institute in Sydney has discovered that a hormone, known as neuropeptide Y (NPY) is released into the body during times of stress. Their findings show the hormone can stop the immune system from functioning properly.

“Neuropeptide Y is one of those hormones that gets unregulated or released from neurones when stressful situations occur…it’s known for example that it regulates blood pressure and heart rates so your heart rate goes up but it hasn’t been known that it actually can affect immune cells as well,” said Professor Herbert Herzog, one of the researchers.

Herzog feels it is good to finally have proof of something people have suspected for so long.

“Now we have proven without doubt that there is a direct link and that stress can weaken the immune system and that makes you more vulnerable when you for example have a cold or flu and even in the more serious situations such as cancer can be enhanced in these situations,” said Herzog.

The Garvan Institute study centres on two key events that enable the human body to recognise foreign substances and control invaders. When our body encounters a pathogen (bacteria and viruses), the immune cells retain and interrogate suspects. Their activation is made possible by NPY. These cells then return to the lymph nodes, which are found all over the body, with information about the foreign invaders. The lymph nodes are where decisions about defence are made.

“Most of us expect to come down with a cold or other illness when we are under pressure, but until now we have mostly had circumstantial evidence for a link between the brain and the immune system,” said lead Garvan researcher, associate Professor Fabienne Mackay. “During periods of stress, nerves release a lot of NPY and it gets into the bloodstream, where it directly impacts on the cells in the immune system that look out for and destroy pathogens (bacteria and viruses) in the body.”

In the case of bacteria and viruses, TH1 cells are part of the attack team that is sent out on the ‘search and destroy’ mission. But when their job is done they need to be turned ‘off’ and the immune system reset. The same hormone, NPY, that activates the sentry cells now prompts the TH1 cells to slow down and die.

“Under normal conditions, circulating immune cells produce small amounts of NPY, which enables the immune cells on sentry duty and the TH1 immune cells to operate – it’s a yin and yang kind of situation. But too much NPY means that the TH1 attack is prevented despite the foreign invaders being identified – and this is what happens during stress,” added McKay.

The impact of stress on the body has been observed in athletes. Ph. D researcher at the University of Queensland, Luke Spence, together with the Australian Institute of Sport, studied elite and recreational athletes over five months.

They found elite athletes were more susceptible to respiratory diseases under stress.

“A lot of elite athletes put themselves through vast amounts of physical stress in their training, but also their emotional, psychological stress of feeling the pressure of Australia on their shoulders, wanting to compete and wanting to do their best,” said Spence.

It’s not just athletes who are prone to stress. Pressures at work and at home may cause emotional and mental stress that can be equally damaging. Almost a third of all work absenteeism in Australia is due to illness, costing employers over $10 billion a year.

“I think it has a huge impact for the work force and also for employers – if their employees are constantly stressed, constantly under pressure, they are more likely to get sick,” Spence said.

Further research could lead to the development of new drugs which may inhibit the action of the neuropeptide Y hormone.

Herzog warns people to minimise stress before it becomes a problem.

“Relaxation methods like yoga will help you to prevent that but there will still be people out there that are not responding to that and treatment by interfering with the system will be important,” he said. “There’s obviously some time until such a treatment will be available but this is something we will definitely work towards.”

The Garvan research will be published in the Journal of Experimental Medicine, Volume 202, No. 11.

The Icelandic Prime Minister Jóhanna Sigurðardóttir and her coalition government narrowly escaped a commitment to resign as a €3.8 billion bill to repay British and Dutch savers following the collapse of Icesave online banking passed. The vote margin was only three votes.

Only a matter of hours before the anticipated final vote, Wikileaks announced the disclosure of one of 23 documents suppressed by the Icelandic Minister of Finance: an apparent legal summary of meetings between Icelandic and EU representatives held in Brussels in November 2008. The leaked document discusses the then-assessed liabilities of Iceland at 60% of GDP, considerably higher than the reported 40% which repaying Icesave deposit holders entails.

Amongst the other details in the report is emphasis of the deep-seated anger of the Icelandic people at the situation around the financial collapse, particularly the UK’s use of anti-terrorism legislation in its approach to the country’s banks. Iceland’s interpretation of the situation, and its financial treaty obligations with the EU, considered foreign deposits lost through force majeure. All 27 EU members disagreed with Iceland’s interpretation and Peter Mandelson, although he resigned from the Barroso Commission in October, presented the legal position that Iceland could not pass legislation that did not ensure treaty-mandated minimum balance returns from failed Icelandic banks.

Leaked private communication from Ingibjörg Sólrún Gísladóttir, Iceland’s then-foreign minister, compared the potential liabilities the country faced with the reparations imposed on Germany by the Treaty of Versailles in the wake of World War I.

Three banks failed in the financial crisis: Kaupthing, Glitnir, and Landsbanki. As the list of creditors emerged it was found that, among others, UK councils had around £900 million with the banks. Landsbanki agreed to repay the majority of funds held, giving council depositors priority status. Approximately £200 million on deposit with Glitnir is at-risk; the bank has stated the councils will be treated equally with all other creditors seeing them likely to only recover 30% of the amount Glitnir held.

Kaupthing faces other difficulties. The UK’s Serious Fraud Office began an investigation earlier this month into the bank’s UK activities. At issue are allegations savers were misled into selecting one particular account type, plus suspicious financial activity suggesting substantial amounts were moved out of the bank in the days prior to its collapse.

At present, UK councils have received little more than ten percent of their over £900 million deposits. They are among over 8,500 creditors claiming a staggering total of £20 billion. The largest single claimant is the British Depositors’ and Investors’ Guarantee Fund seeking €5 billion, and, of some note, Formula One racing team Williams claiming around £10 million in unpaid sponsorship from Glitnir who took on the liability from the Icelandic buyers of Hamleys.

Debt to 84% government-owned Royal Bank of Scotland (RBS) by Glitnir stands at around £500 million; much of the actual debt written off in 2008 as RBS posted £24 billion losses. Further write-offs by the bank are expected to total less than £50 million.

Icelanders resented the discovery that fifteen senior ex-employees of Landsbanki claim €14 million between them, including a single claim of €2.7 million. Suspicion exists that the banks arranged substantial interest-free loans for various of their shareholders and executives.

Today’s announcement of the Icelandic government’s agreement to pay out €3.8 billion keeps their application for EU membership on-track, although each one of the country’s 320,000 citizens effectively faces a €12,000 debt.

Businessman Rocky De La Fuente took some time to speak with Wikinews about his campaign for the U.S. Democratic Party’s 2016 presidential nomination.

The 61-year-old De La Fuente resides in San Diego, California, grew up in Tijuana, and owns multiple businesses and properties throughout the world. Since getting his start in the automobile industry, De La Fuente has branched out into the banking and real estate markets. Despite not having held or sought political office previously, he has been involved in politics, serving as the first-ever Hispanic superdelegate to the 1992 Democratic National Convention.

De La Fuente entered the 2016 presidential race last October largely due to his dissatisfaction with Republican front-runner Donald Trump. He argues he is a more accomplished businessman than Trump, and attacks Trump as “a clown,” “a joke,” “dangerous,” and “in the same category as Hitler.” Nevertheless, De La Fuente’s business background begets comparisons with Trump. The Alaskan Midnight Sun blog described him as the Democrats’ “own Donald Trump.”

While receiving only minimal media coverage, he has campaigned actively, and according to the latest Federal Election Commission filing, loaned almost US$ 4 million of his own money to the campaign. He has qualified for 48 primary and caucus ballots, but has not yet obtained any delegates to the 2016 Democratic National Convention. Thus far, according to the count at The Green Papers, De La Fuente has received 35,406 votes, or 0.23% of the total votes cast. He leads among the many lesser-known candidates but trails both Senator Bernie Sanders who has received nearly 6.5 million votes and front-runner Hillary Clinton who has just shy of 9 million votes.

With Wikinews reporter William S. Saturn?, De La Fuente discusses his personal background, his positions on political issues, his current campaign for president, and his political future.

The province of Alberta, Canada is considering legal action against Canadian National Railway for failing to warn that a derailment last week contaminated Wabamun Lake with a hazardous chemical.

The 700,000 litres of heavy Bunker C fuel oil that spilled into the lake asphyxiated birds and killed fish.

In addition, one of the ruptured tanker cars sent 70,000 liters of Imperial Pole Treating Oil into the lake. This oil is a yellow mixture of polycyclic aromatic hydrocarbons and aliphatic hydrocarbons. Naphthalene, a component of this “very toxic material” is suspected of causing skin cancer if touched and lung or other cancers if inhaled.^[1] Inhalation is promoted by actions that cause splashing or foaming. The mineral oil is used in connection with pentachlorophenol for preserving wooden utility poles.

Wabamun Lake is a popular summertime recreational area about 65 kilometers (40 miles) west of Edmonton, Alberta.

The 766-megawatt Keephills power generating plant, one of 3 in Wabamun, was shut down because the coal-fired plant uses water from the lake. Edmonton’s health authority ordered people not to swim, boat or rescue animals in the lake and to stop using its water or any water from nearby wells for cooking, drinking, showering or brushing teeth. These warnings came 3 days after many residents, including children, had been wading into the oil slick without protective clothing to save wildlife injured by the spill and others had been routinely depending on the lakewater for home use. Why the alert was not issued sooner remains under investigation and may result in criminal charges. Canadian National Railway had been informed of the nature of the oil when it was loaded by Imperial Oil Ltd., Canada’s largest petroleum company. Imperial Oil is posting informational updates on a special website [2]. In addition The Wabamun Residents Committee has established an information website [3].

Every September, the Apple iPod is redesigned. Last year saw the release of the iPod Nano 5th generation, bringing a video camera and a large range of colours to the Nano for the first time. But as Apple again prepares to unveil a redesigned product, the company has released their quarterly sales figures—and revealed that they have sold only 9m iPods for the quarter to June—the lowest number of sales since 2006, leading industry anylists to ponder whether the world’s most successful music device is in decline.

Such a drop in sales is not a problem for Apple, since the iPhone 4 and the iPad are selling in high numbers. But the number of people buying digital music players are concerning the music industry. Charles Arthur, technology editor of The Guardian, wrote that the decline in sales of MP3 players was a “problem” for record companies, saying that “digital music sales are only growing as fast as those of Apple’s devices – and as the stand-alone digital music player starts to die off, people may lose interest in buying songs from digital stores. The music industry had looked to the iPod to drive people to buy music in download form, whether from Apple’s iTunes music store, eMusic, Napster or from newer competitors such as Amazon.”

Mark Mulligan, a music and digital media analyst at Forrester Research, said in an interview that “at a time where we’re asking if digital is a replacement for the CD, as the CD was for vinyl, we should be starting to see a hockey-stick growth in download sales. Instead, we’re seeing a curve resembling that of a niche technology.” Alex Jacob, a spokesperson for the International Federation of the Phonographic Industry, which represents the worldwide music industry, agreed that there had been a fall in digital sales of music. “The digital download market is still growing,” they said. “But the percentage is less than a few years ago, though it’s now coming from a higher base.” Figures released earlier this year, Arthur wrote, “show that while CD sales fell by 12.7%, losing $1.6bn (£1bn)in value, digital downloads only grew by 9.2%, gaining less than $400m in value.”

Expectations that CDs would, in time, become extinct, replaced by digital downloads, have not come to light, Jacob confirmed. “Across the board, in terms of growth, digital isn’t making up for the fall in CD sales, though it is in certain countries, including the UK,” he said. Anylising the situation, Arthur suggested that “as iPod sales slow, digital music sales, which have been yoked to the device, are likely to slow too. The iPod has been the key driver: the IFPI’s figures show no appreciable digital download sales until 2004, the year Apple launched its iTunes music store internationally (it launched it in the US in April 2003). Since then, international digital music sales have climbed steadily, exactly in line with the total sales of iPods and iPhones.”

Nick Farrell, a TechEYE journalist, stated that the reason for the decline in music sales could be attributed to record companies’ continued reliance on Steve Jobs, CEO of Apple, saying that they had considered him the “industry’s saviour”, and by having this mindset had forgotten “that the iPod is only for those who want their music on the run. What they should have been doing is working out how to get high quality music onto other formats, perhaps even HiFi before the iPlod fad died out.”

When Jobs negotiated a deal with record labels to ensure every track was sold for 99 cents, they considered this unimportant—the iPod was not a major source of revenue for the company. However, near the end of 2004, there was a boom in sales of the iPod, and the iTunes store suddenly began raking in more and more money. The record companies were irritated, now wanting to charge different amounts for old and new songs, and popular and less popular songs. “But there was no alternative outlet with which to threaten Apple, which gained an effective monopoly over the digital music player market, achieving a share of more than 70%” wrote Arthur. Some did attempt to challenge the iTunes store, but still none have succeeded. “Apple is now the largest single retailer of music in the US by volume, with a 25% share.”

The iTunes store now sells television shows and films, and the company has recently launced iBooks, a new e-book store. The App Store is hugely successful, with Apple earning $410m in two years soley from Apps, sales of which they get 30%. In two years, 5bn apps have been downloaded—while in seven years, 10bn songs have been purchased. Mulligan thinks that there is a reason for this—the quality of apps simply does not match up to a piece of music. “You can download a song from iTunes to your iPhone or iPad, but at the moment music in that form doesn’t play to the strengths of the device. Just playing a track isn’t enough.”

Adam Liversage, a spokesperson of the British Phonographic Industry, which represents the major UK record labels, notes that the rise of streaming services such as Spotify may be a culprit in the fall in music sales. Revenues from such companies added up to $800m in 2009. Arthur feels that “again, it doesn’t make up for the fall in CD sales, but increasingly it looks like nothing ever will; that the record business’s richest years are behind it. Yet there are still rays of hope. If Apple – and every other mobile phone maker – are moving to an app-based economy, where you pay to download games or timetables, why shouldn’t recording artists do the same?”

Well, apparently they are. British singer Peter Gabriel has released a ‘Full Moon Club’ app, which is updated every month with a new song. Arthur also notes that “the Canadian rock band Rush has an app, and the industrial rock band Nine Inch Nails, led by Trent Reznor – who has been critical of the music industry for bureaucracy and inertia – released the band’s first app in April 2009.” It is thought that such a system will be an effective method to reduce online piracy—”apps tend to be tied to a particular handset or buyer, making them more difficult to pirate than a CD”, he says—and in the music industry, piracy is a very big problem. In 2008, the International Federation of the Phonographic Industry estimated that 95% of downloads were illegitimate. If musicians can increase sales and decrease piracy, Robert says, it can only be a good thing.

“It’s early days for apps in the music business, but we are seeing labels and artists experimenting with it,” Jacob said. “You could see that apps could have a premium offering, or behind-the-scenes footage, or special offers on tickets. But I think it’s a bit premature to predict the death of the album.” Robert concluded by saying that it could be “premature to predict the death of the iPod just yet too – but it’s unlikely that even Steve Jobs will be able to produce anything that will revive it. And that means that little more than five years after the music industry thought it had found a saviour in the little device, it is having to look around again for a new stepping stone to growth – if, that is, one exists.”

The Church of Scientology has threatened legal action in order to take over ownership of the domain name of a web site which links to the odd behaviour of one of the world’s most famous scientologists: Tom Cruise.

http://ScienTOMogy.info has apparently received a fax and at least 6 emails in the span of 2 days from Scientology lawyer Ava Paquette of Moxon & Kobrin threatening a lawsuit of up to $100,000 if the domain name ownership is not transferred. This type of letter is often called a cease and desist letter.

The owners of scienTOMogy.info have posted the complaints and their replies, saying that the site simply expresses opinion, does not make any claims, and clearly states that it has no connection to the Church of Scientology. “The site was put up as a single source to view all the recent hype Tom has made about the church – it does nothing but show Tom, so we are at a loss as to why the church is acting so rashly.”

The Church of Scientology is notorious for pursing legal action against its critics, under the name of the “Religious Technology Center” (RTC). It previously made headlines when it used the US’s Digital Millennium Copyright Act to remove xenu.net, a site critical of Scientology, from Google’s listings.
