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!

According to the Alcohol Tobacco and Firearms Agency or ATF, at least 686 sticks of dynamite and at least 30 pounds of ammonium nitrate were stolen from Gold Mountain Mine Company in Big Bear City, California located in San Bernardino County. Fuel oil and mining equipment are also among the items stolen. When combined, the fuel oil and ammonium nitrate become combustible and authorities fear what could be done with the explosives.

“The obvious concern is someone stole it, and what are they going to do with it? This is a quantity of explosives that could do significant damage. We need to recover these items,” said John D’Angelo, spokesman for the ATF.

The thieves cut locks on the gate that leads to the facility and then cut the locks on a metal storage bin and stole its contents and everything inside the facility. The man responsible for mining operations in the area does so as a hobby. The robbery was reported on May 3.

“We urge anyone who has information about this theft to contact ATF and the San Bernardino Sheriff’s Department. Our job is to keep the public safe. We take the theft of explosives extremely seriously, and we will relentlessly follow up every lead until we solve the case,” said John A. Torres who is the special agent in charge of the ATF in Los Angeles.

Authorities have offered a $25,000 reward for information about the crime that leads to an arrest and conviction.

Fuxin city (???; pinyin: Fùx?n shì) – An underground explosion in a mine in China’s northeastern Liaoning Province has left over 200 miners dead.

Current figures say 203 miners were killed, and another 22 were injured with 13 miners still missing. The blast occurred at 3:49pm local time on Monday afternoon.

The explosion, 242m underground, is believed to have been caused by gas igniting.

This morning a rescue team arrived at the site in Fuxin to attempt locate survivors and treat injured.

China has a history of major mining accidents. Last November, 166 miners died in an explosion in mine in Chenjiashan mine in Shaanxi province. In 2004, a official figures show that 5,000 workers died in accidents in mines, 35% of the world-wide death toll in coal mines.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Dr. Jim Gill: Of course not.

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

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

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

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

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

A woman has died after being struck by a hose attached to a fire truck in Cambridge, Massachusetts. Gertrude King, aged 82, came from the town of Somerville.

On Tuesday, she was standing on a median strip on a road to allow a fire truck to pass through. As the truck passed, the fire hose attached to it dislodged and was left dragging behind the vehicle; the elderly woman was struck in the knees by the trailing hose. According to Cambridge Police, Gertrude died in Massachusetts General Hospital on Thursday. Deputy Superintendent Jack Albert of Cambridge Police stated, “[w]e do know the hose is 200 feet long and we believe that the hose was completely off the truck and being dragged at the time it struck.”

An investigation is underway. The police have said that, at present, they are unable to determine the cause of the loose hose. Gertrude was said to be unable to get out of the way in time. Elanor Raniri, who lives in the same apartment complex as Gertrude, said, “[s]he was very special. It’s unbelievable. It’s hard to take in.”

Swiss mining company Glencore announced yesterday the closure of its coal mine in Tahmoor, New South Wales, Australia. The mine is to be closed by early 2019, pointing to the downturn of coal prices in global markets.

Glencore stated, “The decision has been made as a result of continued low prices in global coal markets, which has meant the economic return from reserves still available at Tahmoor are not sufficient to warrant the investment required to mine them”.

The closure will result in a loss of 350 jobs according to the company, who said they are consulting with the employees.

The mine is not the only operation impacted by the fall of global coal and commodity prices. The Australian arm of mining magnate Peabody Energy has reported losses of almost A$3 billion in 2015. According to latest financial reports for Peabody subsidiary Peabody Australia Holdco lodged via Australian Securities and Investments Commission, the company earned a net loss of A$2.7 billion — after a loss of A$1.2 billion in 2014. Accountants at Peabody Australia have warned the mine might not be able to continue operating, with the market persistently weak since December.

Despite low coal and commodity prices, both the major political parties have been supportive of coal mines. While appearing on the ABC’s Q&A program on Monday night, Coalition MP Steve Ciobo confirmed party support of coal mines. In response to an audience member question, concerning what policies the panellists had planned to combat job and economic loses in Queensland after the mining boom, Ciobo stated the Coalition government supports Adani’s new Carmichael mine in the Galilee Basin — as an example of “transitioning” the state’s economy.

Labor MP Terri Butler said although she doesn’t personally support Adani’s Carmichael project, the state Labor government “didn’t have much discretion” surrounding its approval. Meanwhile, Greens party leader Richard Di Natale criticised responses from the panellists claiming the “great tragedy” is both major parties support of coal mines such as Carmichael.

“If you care about tourism you don’t open up a whopping great big coal mine and fuel catastrophic global warming”, said Di Natale.

Di Natale accused both major parties of being deceitful in “slashing” both the target of and agency funding for renewable energy, leaving no plan to realize the investment potential of the renewable sector.

As many as 3,200 mine workers became trapped in the in Elandsrand mine, a gold mine in South Africa about 50 miles (80 km) west of Johannesburg in Carletonville, Gauteng, after an incident on October 3. All miners have been rescued, and none of them were injured. The mine is owned by Harmony Gold Mining Corporation.

The mining company says that a lift electrical cable broke on a basket that was carrying miners, trapping thousands at least 2,200 meters (1.3 miles) below the earth’s surface. Reports from MSNBC and the Guardian Unlimited say that the shaft may have collapsed when a water or air pipe burst. The rescue operation went well with no complications, with the rescue taking just under 24 hours to complete.

“They were underground when the accident happened and they were not able to surface because an electric feeder cable that is connected to the mine lift was severed,” said a spokeswoman for the mining company, Amelia Soares. The snap was caused by a “fatigued” air pipe which burst and fell down the shaft damaging the “steelwork and electrical feeder cords,” added Soares. “They are all in good condition.”

“They are all safe. There have been no injuries or deaths,” said CEO of Harmony mining, Graham Briggs who also said that the miners were previously contacted and were given “food and water.”

Earlier reports had stated that Lesiba Seshoka, a spokesman with the National Union of Mineworkers, said that the miners have not been heard from for hours and that they could have been enduring temperatures as high as 105 degrees Fahrenheit (40 degrees Celsius).

“This is a terrible situation. The only exit is blocked, probably by a fall of ground,” said Seshoka.

Rescue workers used a mine shaft that is next to the damaged one in an attempt to reach the trapped miners, and lifted them out, 75 at a time. There was no emergency exit in the shaft which is reported to have “not been maintained for ages,” added Seshoka.

“An escape route is the most important thing and they have failed miserably. They need to ensure that the shaft is maintained. This is why we have this disaster. Our main worry is for more than 3,000 people who are underground,” said National Union of Mineworkers for S. Africa chairman, Deon Boqwana.

Current reports say that “negligence” was the initial cause for the pipe burst and that there has been a history of negligence from the mine. “We suspect negligence. Because of continuous operations there is no time to make adequate checks,” said the President of the Miners union, Senzeni Zokwana to reporters during a news conference.

The Elsrand mine is currently under development and has been since February 2001 when Harmony bought the mine. Officials state that the mine will remain closed for a minimum of six weeks, while an investigation is performed, and the mine is deemed safe for miners to continue working in it.

The mine is located in the Witwatersrand Basin of South Africa, which is said to be the location of the largest area of raw gold on the planet.

At least two people have died and at least eight to ten were injured after two semi trucks collided in a truck tunnel on Interstate 5 (Newhall Pass) between Los Angeles and Santa Clarita California, United States, causing the tunnel to be completely shut down on both north and southbound lanes.

At approximately 11:00 p.m. (pacific time), two semi trucks collided and at least 13 other trucks smashed into the wreckage causing a massive fire. Firefighters are using foam to control the flames, which could take several hours to put out.

Officials say that the debris could take a day or more to remove and that a full inspection will have to be done on the tunnel before it can be used again because officials say that the structure of the tunnel has been compromised.

“It has impacted the structural stability of the tunnel,” said John Tripp the Fire Chief for Los Angeles County who also said that there may be more people trapped in the wreckage.

“We’re going to have to do a very methodical search. There could be unfortunately more people that were not able to escape,” added Tripp.

The tunnel is 200 feet long.
