Spanish police believe they are close to capturing Aribert Heim, the 91-year-old known as “Dr. Death”. Dr. Heim, described by The Times as “the most wanted Nazi still believed to be alive”, is thought to be living in the town of Palafrugell in the Costa Brava area of Spain.

Heim worked as a doctor in a number of Nazi Germany concentration camps (Mauthausen, Sachsenhausen and Buchenwald) carrying out a series of experiments on the camp’s Jewish inmates. His experiments reportedly included operating on a patient without anaesthetic to see how much pain a human being could endure, and injecting petrol into the bloodstream, then timing how long it took for the victim to die. Hundreds of people are believed to have died as a result of these experiments.

The Times reports that Heim led a normal civilian life after the end of the Second World War, but fled Germany in 1962, when the authorities were about to issue a warrant for his arrest. Nazi hunters, including researchers from the Simon Wiesenthal Center, have been looking for him ever since. The center’s founder, Simon Wiesenthal, was himself active in pursuing Heim prior to his death last month.

German police received a tip six weeks ago by an Israeli citizen who met a man in Ibiza with characteristics similar to Heim. The police acknowledged the information was helpful. Other evidence pointing the trail to Palafrugell involve banking transfers and tax filings.

In Friday’s National Hockey League contest between the Philadelphia Flyers and the Boston Bruins at the TD Banknorth Garden in Boston, Massachusetts. Peter Forsberg almost netted his first “hat trick” in a Flyers uniform. At one point during the game, he had been given credit for three goals, however an official review took his first goal away, and officially he scored his eighth goal of the season at 13:06 in the second period with assists from Simon Gagne and former Hartford Whaler Sami Kapanen.

To date, there have been 24 hat tricks (3 or more goals in one game) in this NHL season.

Forsberg, a 32 year old native of Sweden, recently joined the Flyers for the 2005-2006 season after spending the NHL lockout season with Modo, Sweden.

The Flyers ended up winning the game 5-3, adding yet another loss to an already disappointing Bruins season.

A recently created Danish clothing company is selling on the internet T-shirts in order to support the clandestine radio station of the Colombian guerrilla group Revolutionary Armed Forces of Colombia (FARC) and the graphical workshop of the Popular Front for the Liberation of Palestine (PFLP). In fact the money will be used by these groups to carry on their terrorist activities. FARC activities include kidnappings, masacres, bombs, extortions and the drug trade.

Fighters and Lovers is selling the T-shirts at 170 DKK (US$27.6), from which 35 DKK (US$5.7) are to be destinated to support both armed groups.

Anna Duever, Fighters and Lovers PR chief, said to Spanish news agency EFE that their objective is to “defend freedom and social justice, which is FARC and PFLP are fighting for”. Duever believes the fact the FARC has been included by the EU in its terrorist group list is a “political game”. “We pay our taxes in Denmark, and that money is used for financing the troops our government has sent to Iraq. That’s terrorism. Besides, in Colombia there’s a regime oppressing population and torturing and killing its people”, she said.

Colombian Foreign Affairs Minister, Carolina Barco, said to local media that “financing terrorist groups is unacceptable and goes against all the international norms. Yesterday [Tuesday 19] our ambassador contacted the Danish government, we sent a protest note and have demanded an explanation.”

A year ago, a Danish NGO named Oprør (“Rebelion”) stated it had donated money to the Colombian guerrilla. A new antiterrorism law in Denmark may punish it.

The US-based Cessna Aircraft Company, a subsidiary of Textron Inc., is expected to statically display seven of its aircraft and a mock-up of its latest business jet large cabin concept at the 47th International Paris Air Show, dubbed the LCC.

The seven aircraft expected to be on display are the Citation CJ2+, Citation Encore+, Citation XLS, and Citation Sovereign business jets, a Grand Caravan, a 206 Stationair, and a 172 Skyhawk single engine piston aircraft.

Cessna Chairman, President and CEO Jack Pelton said of the exhibit, “There is so much synergy now with other companies under the Textron corporate banner – companies like Bell Helicopter and Textron Systems – that we felt it made sense for us to return as an exhibitor to the Paris Air Show… We are particularly excited to have our large cabin mockup as the highlight of our exhibit.”

Cessna originally announced plans for a new large model of business jet for the Citation range at last year’s annual National Business Aviation Association meeting, and the idea has been in development since, culminating in the new large cabin concept design. The mock-up at the Paris Air Show includes a large galley, seating for nine passengers, a toilet and a dummy flight deck.

Cessna claim the new design, which outsizes their previous large cabin and long-range business jets, would “set a new standard for performance, cabin comfort, passenger amenities and environmental friendliness,” if launched.

Cessna refuse to release details such as exact internal design specifications and manufacturers of avionics and engines unless the new model actually enters production. Cessna Senior Vice President of Sales & Marketing Roger Whyte told reporters that preliminary wind tunnel testing had “fully met… expectations” and that they had “received extremely positive reaction to the performance parameters as well the cabin design of the proposed aircraft from our customer base”, although he warned that there are still a number of processes to be completed before Cessna actually decide whether or not to launch the new model.

South African president Thabo Mbeki has arrived in Harare today to talk with Zimbabwean president Robert Mugabe about the upcoming presidential run-off election. This comes amid claims that violence has risen in the country over the last few days.

The Zimbabwe Association of Doctors for Human Rights claim there has been a “dramatic escalation in incidents of organised violence and torture” after the recent elections with “more than 900” documented as injured. The organization said in a statement that “the level of brutality and callousness exhibited by the perpetrators is unprecedented and the vicious and cowardly attacks by so-called war veterans on women, children and the elderly shames the memory of all true heroes of the liberation struggle”.

Mr. Mbeki is acting as a mediator for the Southern African Development Community (SADC) and may have discussed elections and the recent crackdown on opposition by the Mugabe government, which has included the arrest of Davison Maruziva, editor of free newspaper The Standard, 22 deaths, the displacement of 40,000 opposition farming families and such a casualty influx into Harare hospitals that they are worried that plaster of Paris bandage supplies will soon be “exhausted”.

Talks between the two leaders at State House lasted for more than three hours before Mbeki left for the South African embassy in Harare.

Morgan Tsvangirai, leader of the largest opposition party, the Movement for Democratic Change (MDC), plans to announce whether he will stand for the run-off election in the South African city of Pretoria, where he is currently residing, tomorrow at 9:00 UTC.

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!

On Monday, digital security researchers Mathy Vanhoef and Frank Piessens of Belgium’s KU Leuven university publicly disclosed a security vulnerability in the WPA2 Wi-Fi (wireless local-area networking) protocol, which they called KRACK (for Key Reinstallation Attack). Their study claimed KRACK affects every modern device using Wi-Fi; it can be fixed by a software update, researchers said.

Vanhoef wrote, “Attackers can use this novel attack technique to read information that was previously assumed to be safely encrypted. This can be abused to steal sensitive information such as credit card numbers, passwords, chat messages, emails, photos and so on.” Vanhoef notified vendors about the flaw in July, including UNIX-like operating system OpenBSD. “If your device supports Wi-Fi, it is most likely affected. […] In general, any data or information that the victim transmits can be decrypted”, he wrote.

The study papers, which were submitted for review on May 19, were kept in confidence allowing companies to fix the security flaw. The United States-based Computer Emergency Response Team (CERT) informed vendors on August 28. The Wi-Fi Alliance said it “could be resolved through a straightforward software update.” OpenBSD released their software patch on August 30.

Exploring the flaw which affected every device the researchers had tested, National Cyber Security Centre of the UK said “the attacker would have to be physically close to the target”. But due to this flaw, an attacker can send malware or ransomware on the websites, Vanhoef claimed.

Linux-based operating systems including Android v6.0 and higher are especially affected by this flaw, while Windows and iOS are not as vulnerable as Android by this flaw as they do not fully implement WPA2.

Microsoft reportedly has released security patches for Windows 7, 8, 8.1 and 10. Google said Android operating systems would receive the updates in the software update scheduled to be made available on November 6. Apple has implemented the patch in the beta versions of their operating system iOS, macOS, tvOS and watchOS, however it is yet to roll out patches for stable operating systems.

WPA2 protocol has been used for more than a decade, and has been compulsory for Wi-Fi since 2006. KRACK would also affect various home appliances which can be controlled over Wi-Fi, within the so-called “Internet of things”. Andrew Martin from Oxford University said, “We can be sure a lot of these devices won’t be patched[…] Whether that matters for this attack or only for some future attack is yet to be seen.”

The study and its findings are scheduled for presentation at the ACM (Association for Computing Machinery) Computer and Communications Security conference on November 1.
