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!

Access to search engine Google has been limited and most of Google’s online services cannot be accessed in Turkey. The access limitation happened due to the blocking of an IP set that belongs to Google. These IP addresses were shared between YouTube and other Google services.

The Turkish news site Hürriyet Daily News reports that Turkey’s Telecommunications Communication Presidency (TCP) (a government agency that manages Turkish ISPs) indefinitely shut off access to several Google services. The shut-off came after the banning of YouTube for alleged insults against Turkish Republic founder Mustafa Kemal Atatürk. TCP released an official statement Friday, saying it had blocked access to some Google IP addresses “because of legal reasons”. Under Turkish law, it is an offence to “insult Turkishness.”

Softpedia states that the limited access to Google could be a result of the government trying to block specific DNS addresses that relate to Google, as part of its ongoing attempts to block YouTube. Since Google services share common software and IP addresses, the search engine itself suffers from access restrictions. Turkish citizens are concerned that this move of the governmental agency was another step towards a complete ban on Google, as exists in China.

Several Internet sites have been banned in Turkey in recent years, and although some of them were subsequently unbanned, most of them remain inaccessible. Engelli Web, a website listing banned sites reports that currently YouTube (since May 2008), Last.fm (since June 26, 2009), and Spanish newspaper El Mundo (since May 14, 2010) are among the banned sites in Turkey. MySpace and WordPress were also among banned sites for a period of time. Websites will be blocked following a court decision or if TCP decides to block on its behalf.

RetweetToday reports that Turkish citizens on Twitter have also reported access problems. Comments about the blockage are being shared using hashtags such as TurkeyCensorGoogle and TurkeyGoogleBan, as well as NoGoogleNoWeb.

Last week, on December 8, US-based software company Red Hat announced plans to shift their focus away from CentOS in favour of CentOS stream.

Started in 2004, CentOS has been a free-of-cost free/libre open source software which provided binary-code compatibility with Red Hat Enterprise Linux (RHEL) — Red Hat’s GNU General Public Licensed paid operating system. Gregory Kurtzer told Wikinews he started CAOS Linux around the time when Red Hat announced End of Life for their Red Hat Linux in favour of subscription-based Red Hat Enterprise Linux. CAOS was succeeded by CentOS when Rocky McGaugh, a developer of CAOS rebuilt the source code of RHEL to provide a monetarily free alternative. CentOS was absorbed into Red Hat in 2014, with Red Hat gaining the trademark rights of “CentOS”.

Red Hat also sponsors the development of the Fedora operating system. Until now, software development took place on Fedora, which was later adopted in RHEL, which the Red Hat maintained and provided support for, for those customers who had RHEL subscription. CentOS would then follow RHEL’s release cycle to provide the same features free of cost, but without the support.

Stream was announced in September 2019, just two months after Red Hat was acquired by IBM. CentOS Stream’s development cycle had new features added to it before the features became a part of RHEL. Stream receives more frequent updates, however, it does not follow RHEL’s release cycle.

With CentOS Stream, developments from the community and the Red Hat employees would take place beforehand on both Fedora, and Stream as a rolling release, before those features are absorbed into RHEL. CentOS followed the release cycle of RHEL and therefore it was a stable distribution. Features available in CentOS were tried and tested by Fedora, and then RHEL maintainers.

Red Hat’s Chief Technical Officer Chris Wright wrote in the announcement “CentOS Stream isn’t a replacement for CentOS Linux; rather, it’s a natural, inevitable next step intended to fulfill the project’s goal of furthering enterprise Linux innovation.” Since the announcement was made, many people expressed their anger on Internet Relay Chat (IRC), Reddit and CentOS project’s mailing list. CentOS 8’s End of Life (EOL) has been moved up from May 2029 to December 31, 2021, while CentOS 7 is expected to receive maintenance updates through June 2024, outliving CentOS 8.

Soon after Red Hat’s announcement, Kurtzer announced his intentions to develop Rocky Linux, to fill the role CentOS had been playing for so long. Kurtzer said Rocky Linux was named after Rocky McGaugh. “Thinking back to early CentOS days… My cofounder was Rocky McGaugh. He is no longer with us, so as a H/T [hat tip] to him, who never got to see the success that CentOS came to be, I introduce to you…Rocky Linux”, Kurtzer wrote. Wikinews discussed with Kurtzer the beginning of CentOS, and future of Rocky Linux.

While no formal date of release has been announced for Rocky Linux, Kurtzer said they are planning to release the CentOS replacement before the end of life of CentOS 8. Kurtzer also said Rocky Linux will run on both x86-64 and ARM-based processors, and CentOS users would be able to convert their OS to Rocky Linux just by running a single command.

Saying Rocky Linux is for the community, Kurtzer said he “take[s] the responsibility of ensuring that all decisions are in favor of the community and the project and free from corporate control” including his own company. Talking about the attention from the userbase Rocky Linux has received, Kurtzer said, “I have never seen an open community come together this fast and be this passionate about working together towards a common goal.”

A court in England, UK has jailed a policeman for ten months after he was convicted of defrauding his car insurance company.

Police Constable Simon Hood, 43, arranged for a friend who dealt in scrap metal to dispose of his Audi TT, then claimed it had been stolen.

Hood had been disappointed with the car’s value when he tried to sell it two years after its purchase in 2008. He arranged for friend Peter Marsh, 41, to drive the vehicle to his scrapyard in Great Yarmouth, Norfolk. Marsh then dismantled the vehicle with the intent of disposing of it, but parts were later found wrapped in bubblewrap at Ace Tyre and Exhaust Centre.

Marsh picked up the TT from outside nearby Gorleston police station. Records show mobile phone conversations between the conspirators that day in March, both before and after the vehicle was reported stolen. The pair denied wrongdoing but were convicted of conspiring to commit insurance fraud after trial.

The fraud was uncovered after Hood told former girlfriend Suzanne Coates of the scheme. It was alleged before Norwich Crown Court that he had confessed to her in an effort to resume their relationship. Coates said that after the pseudotheft, Hood told her “he didn’t want to look for it. He said it would be like looking for a needle in a haystack, which I thought was a bit strange.”

Shortly afterwards Hood suggested they should become a couple once more, she said; she challenged his version of events regarding the car: “He said he did it but I couldn’t tell anyone. He said he did it with Peter. Peter had a key and took the car away and it was going to be taken to bits and got rid of so it was never found.”

Hood was defended by Michael Clare and Marsh by Richard Potts. Both lawyers told the court that their clients had already suffered as a result of the action in mitigation before sentencing. Clare said Hood had resigned from the police after fifteen years of otherwise good service and risked losing his pension. “It is not a case where his position as a police officer was used in order to facilitate the fraud,” he pointed out. “His career is in ruins.” Hood is now pursuing a career in plumbing.

Potts defended Marsh by saying that he, too, had already suffered from his actions. His own insurers are refusing to renew their contract with him when it expires and his bank withdrew its overdraft facility. His business employs 21 people and Potts cited Marsh’s sponsorship of Great Yarmouth In Bloom as amongst evidence he supported his local community.

Judge Alasdair Darroch told Marsh that he did accept the man was attempting to help his friend. He sentenced Marsh to six months imprisonment, suspended for two years and ordered to carry out 250 hours of community service. He was more critical of Hood:

“As a police officer you know the highest possible standards are demanded by the public. You have let down the force. You knew throughout your career that policemen that get involved in serious dishonesty get sent to prison.”

Zach Scruggs, a lawyer for United States Senator Trent Lott, says that State Farm Insurance Company is destroying records related to claims for damage from Hurricane Katrina.

The records allegedly contain information saying that State Farm fraudulently denied insurance claims made by its policy holders, including Lott, that had homes there were damaged or destroyed when Hurricane Katrina came ashore on the Gulf Coast.

Scruggs said that Lott has “good faith belief” that many employees of the insurance company in Biloxi, Mississippi are destroying engineer’s reports that were inconclusive as to whether or not water or wind was the main cause of damage to the buildings affected by the hurricane.

Lott is among thousands of home and/or business owners who had their property damaged or destroyed during the hurricane and had their claims denied because State Farm claimed that their policies don’t cover damage caused by floods or water that was driven by the wind.

State Farm has not issued a statement on the matter so far.

In a vote of 74-25 last Thursday, the US Senate passed a measure that would change bankruptcy laws, making it harder for individuals seeking relief from their debt burden to avoid repayment. Almost twenty Democrats joined Republicans, who currently hold a majority of the seats in the US Senate, in passing the bill.

Lobbyists for credit card companies and financial services firms have worked for the bill during the last two administrations. A similar measure passed both the Senate and House during the previous administration, but then President Bill Clinton pocket-vetoed the measure in 2000.

Democrats sought to soften the bill by allowing bankruptcy filers to negotiate directly with lenders for relief, but the amendments were defeated by the Republican-controlled Senate. Proponents of the bill claim the rise of bankruptcy filings to nearly 1.5 million a year shows that abusers of credit use the filings to shield themselves from irresponsible practices.

“There has been an explosion of bankruptcy,” said Iowa Republican Sen. Charles E. Grassley, the bill’s sponsor. “We preserve the principle of a fresh start, but we also establish a principle that if you have the ability to repay some of your debt, you are not going to get off scot-free.” However, Massachusetts Democratic Sen., Edward M. Kennedy said, “This legislation makes the bankruptcy courts of the United States the collection agency for the credit-card industry.”

The bill impacts a broad spectrum of bankruptcy law, but the most significant impact is on personal bankruptcy filings. Individuals who get behind in repaying credit card debt face high interest charges and stiff late payment fees. By only meeting minimum payment requirements, borrowers remit to the lender over the life of the loan an amount in interest and other fees that can far exceed the value of the principal balance of the loan. This can put consumers who run up high balances on various cards at financial risk of default. Critics of the bill blame these aggressive lending practices as a contributing factor in the rising trend of bankruptcy filings from 1996.

The proposed bill doesn’t only affect debtors with credit card debt.

It also affects debtors who have run up large medical bills.

Patients with a past medical history that disqualifies them from full medical coverage, can easily find themselves facing insurmountable medical bills after just a short stay in the hospital. These individuals will no longer be able to get a fresh start after these personal disasters, and will be forced to live in poverty until they can pay off their medical bills as part of their Chapter 13 filing. (Prior to this bill, they would have been able to file Chapter 7, completely discharging their debt.)

Chapter 7, which accounts for 70% of bankruptcy filings, allows individuals to eliminate most non-secured debts after liquidating assets, with the notable exemption of one’s principle residence in most states. The Senate passed bill would change Chapter 7 eligibility by applying a means-test, where those with a median income higher than the state average would be required to file under Chapter 13 provisions. Under Chapter 13 protection, an individual’s debt is not forgiven; rather it is restructured for payment under more lenient terms.

This was the first major overhaul of federal bankruptcy law in many years.

Under the old bankruptcy law, a personal bankruptcy attorney could not be held financially responsible for his clients mendacity. Under the new bankruptcy law, the bankruptcy attorney is responsible for his client’s lies to the Court about his assets and the bankruptcy attorney and his insurance carrier can be held responsible by the Bankruptcy Court.

The result is that personal bankruptcy attorneys (this does not apply to corporate bankruptcy attorneys) are likely to flee the personal bankruptcy field when the new law takes effect. Their insurance companies will not offer the sort of coverage that they would need to continue to practice.

So when consumers need to file personal bankruptcy under the new law, they will be unlikely to find a bankruptcy attorney to represent them. Consumers will have to file pro se: such consumers will be likely to fail due to the complexity of the law.

The bottom line is that the field of personal bankruptcy law as a practice area of law will cease to exist when the new bankruptcy law takes effect, and consumers will be unable to secure legal counsel and so consumers will lose what legal protections counsel now affords them.

Under the new bankruptcy law about one half million Americans will be forest to pay for at lest 5 years on longer they will be held in servitude as chattel they will be completely subservient to a dominating influence of the company that holds the loan. Their loan will be put on the market for sale for profit. The people will be forced to work harder. People who fail to go to court will have a arrest warrant made out in their name and people who refuseto pay. They will be subject to fines and or jail. About fifty thousand Americans will punished by a fine and or about three thousand Americans every year will go to jail under the new bankruptcy law. For some people this will be a third strike they will be put in jail for life.

The bill has the support of President Bush, and its passage in the House sometime next month seems likely. If enacted into law, lending companies will recover more money on what otherwise would be written off as bad loans. Those persons of median and higher income seeking relief would be required to file under Chapter 13 status and pay up to $100 per month under court imposed conditions. It is expected the proposed changes would cause a sharp increase in filings before the new law could take effect.

The International Maritime Bureau, an agency of the International Chamber of Commerce, has stated that 30 sailors were murdered by pirates during 2004. The Bureau’s 2004 Annual Report on Piracy and Armed Robbery against Ships shows that the number killed has increased from the 21 who died in 2003, according to data collected by the IMB Piracy Reporting Centre in Kuala Lumpur, Malaysia.

However, the total number of attacks has decreased–325 recorded attacks, down from 445 in 2003.

Indonesian waters are the most violent, with 93 incidents; one-quarter of the global total of attacks. Tugs and barges are common targets, with crew members often being kidnapped.

Nigeria has the most dangerous waters of any African country. In 2004, there were 28 attacks (down from 39), the third highest number of incidents in the world.
