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!

New York City – Actor Jerry Orbach died in his home in Manhattan at age 69. Orbach was a staple of American cinema, stage and television, with his most recent role being in the NBC police drama “Law and Order.”

Orbach is survived by his wife of 25 years, Elaine Cancilla, and his two sons Anthony and Christopher.

Orbach was born in the tough Bronx borough of New York City in 1935 to a family of entertainers. His father Leon Orbach was an vaudeville actor and his mother Emily Orbach was a radio singer and greeting card writer.

The family moved often to keep up with travelling Vaudeville acts, but eventually settled in Waukegan Illinois where Orbach played football at the local high school. After graduation, Orbach got a summer job at the Chevy Chase Country Club in Wheeling doing odd jobs ranging from stagecraft to small acting parts in plays.

He then studied drama at the University of Illinois before transferring to Northwestern where he studied the Stanislavsky Method of drama acting. In 1955, Orbach dropped out of college and moved to New York City where he got a job as an understudy in The Threepenny Opera.

Orbach continued to work in theater, eventually earning roles in broadway musicals, but by 1961 had grown dissatisfied with being typecast as a musical actor. He tried briefly to break into film without success, and eventually returned to broadway where he earned numerous accolades for his roles in such musicals as “Guys and Dolls” and “Chicago“.

Orbach finally broke into television in the 1980s as a recurring character in shows such as the mystery-drama “Murder She Wrote” and the hit sitcom “Golden Girls“.

He earned the lead role as the title character in his own short-lived series “The Law and Harry McGraw”, a spinoff of “Murder She Wrote”. Orbach also scored key roles in a few Hollywood films, including the action thriller “F/X”, and the dance-musical hit “Dirty Dancing”, but continued to find his mainstay in television crime dramas.

In 1990, he picked up a role in the new NBC crime drama “Law and Order” as the acerbic-witted Lennie Briscoe, a role which soon become a regular job. Orbach continued in this role in addition to movie roles and occasional musical appearances until his death this last week.

Orbach was diagnosed with Prostate cancer in Spring of 2004, a fact he kept private until November when he checked into New York’s Memorial Sloan-Ketting Cancer Center for treatment. In spite of the aggressive nature of the treatment, he died on the evening of December 28.

The United States amusement park operator Six Flags has shut down nine thrill rides at four parks after a 13-year-old girl’s feet were cut off on a tower-drop ride yesterday at Six Flags Kentucky Kingdom in Louisville.

Kentucky state officials said a loose cable on a ride called the Superman Tower of Power severed the girl’s feet above the ankles, but they had not determined how the cable broke free, or at what point in the ride the accident happened. The ride lifts passengers 177 feet (54 metres) straight up, then drops them nearly the same distance at speeds reaching 54 mph (86 km/h).

The girl, whose identity has not been released, was taken to a hospital. Details of her condition were not immediately available.

Six Flags spokeswoman Carolyn McLean told The Courier-Journal that there has never been a major incident on the Tower of Power. Formerly known as the Hellavator, the ride was built in 1995.

In addition to Kentucky Kingdom, rides have been shut down at Six Flags Great America in Gurnee, Illinois; Six Flags St. Louis in Eureka, Missouri; and Six Flags America, Prince George’s County, Maryland.

A Superman Tower of Power Ride at Six Flags Over Texas in Arlington has not been shut down because it is not the same as the ones in Kentucky and the other locations that have been shut, Six Flags spokeswoman Wendy Goldberg told the Associated Press.

The rides that have been shut down are made by a Swiss-owned company called Intamin.

Cedar Fair Entertainment Company said it was shutting down similar thrill rides at its theme parks at Kings Island in Mason, Ohio; Canada’s Wonderland in Vaughan, Ontario; Kings Dominion in Doswell, Virginia; Carowinds in Charlotte, North Carolina; and Great America in Santa Clara, California.

The remains of three children were discovered in a bucket at a home at 1302 Sandford Street in London, Ontario in Canada on Saturday, June 6, 2009. The bodies were in an advanced state of decomposition, so much so that it was originally thought to be a single corpse until further investigation revealed that it was actually the remains of three children.

“He came outside and told everybody he discovered this bucket,” a neighbour of the resident who discovered the remains, told CBC News. “He said his girlfriend had this bucket for two years with gardening stuff in it, and he opened it on Saturday, and it was [filled with] bloody clothes and a blanket, and he called the police.”

“Due to the decomposition it was difficult to see that there was more than one there. The bodies have been decomposing, it could be over a number of years,” said London Police Detective-Superintendent Ken Heslop, “We won’t know anything until, I’m hoping, Thursday or Friday, depending on how long the examinations take.”

Jennifer Sinn, 32, a former resident of the building has been charged with concealing a child’s body and offering an indignity to a dead human body. Neighbours have described her as a recluse staying to herself with parents delivering meals to her. Neighbours have also come forward saying that a young child about one year old has not been seen for awhile and that there had also been two older children. Police are seeking any further information in the case.

There is no report of charges against the man who called the police to report the bodies, who is believed to be the ex-boyfriend of Sinn, who is charged with the crime. Reportedly, she had moved out of the building two weeks prior to the discovery of the bodies.

The London police are following up with local police at various locations where the young lady had resided before.

The provincial forensic pathology unit in Toronto, Ontario will undertake the full autopsies.

Constable Amy Phillipo said, “The investigation into the cause and manner of death of the three infants is continuing.”

The British Conservative-Liberal Democratic coalition government has scrapped plans by the previous government to change the rules on equal pay between men and women.

The previous Labour government included a provision in the Equality Act 2010—Section 78—to allow the government the option to introduce regulations that would require companies to publish details of the difference in pay between male and female employees. If the government had activated such regulations, they would have come into force in 2013. The current government have decided not to activate this requirement and instead will only ask businesses to provide this data voluntarily and will set an “aspiration” to dramatically increase the number of women in senior positions in business.

Lynne Featherstone, the Liberal Democrat MP and coalition Equalities Minister, in announcing the plans stated that the government wishes “to move away from the arrogant notion that government knows best, to one where government empowers individuals, businesses and communities to make change happen.”

Featherstone announced the policy at the School of Management at Cranfield University, who have conducted research finding that only 12.5% of directors of FTSE 100 companies are women, up from 12.2% last year—”glacially slow” progress according to business commentator David Prosser.

Featherstone justified not implementing the pay audits due to the economic costs: “Right at this moment of financial peril to the nation is perhaps not the moment to introduce mandatory pay audits.”

This breaks with a Liberal Democrat manifesto commitment, as well as contradicting Featherstone’s own words two years ago in support of the audit: “A voluntary audit system for private industry is hardly worth the paper it’s printed on. We need to know when the government actually plans to step in if progress isn’t made.”

Women’s groups and trade unions have condemned this move. Dave Prentis, the general secretary of UNISON, Britain’s second largest trade union, said that this is an example of the government “stripping down its commitment to equality”.

Prentis continued: “It is a disgrace that women are still getting paid less than men. This move threatens to turn the clock back on all the progress already made with equal pay.”

Ceri Goddard, the chief executive of the feminist campaigning group the Fawcett Society, condemned the plans: “The persistent gap in pay between men and women is one of the starkest examples of inequality in the UK today. The government’s decision not to bring into force section 78 is a huge disappointment and means this injustice will continue for a long time to come. The government has today consigned another generation of women to lower pay. Their proposal to rely only on voluntary business action on pay isn’t just naive, it sends a dangerous signal that tackling discrimination against women is a choice, not a requirement.”

Yvette Cooper, Featherstone’s shadow minister on the Labour benches, called the news “another broken promise from the government” and said that “scrapping Labour’s plan to increase transparency in pay is a backwards step for women’s equality.”
