Areas in far north Queensland remain without electricity, running water or sewerage after Category 5 Cyclone Larry hit the coast on Monday morning. Queensland Premier Peter Beattie has declared a state of emergency in Innisfail and says he is worried about the outbreak of diseases. Army engineers are among more than 1,000 people assisting in Queensland’s cyclone relief effort.

Premier Beattie says it could be more than a week before power is restored in Innisfail. “The whole bloody place is blown apart… this is going to be a long, slow recovery,” he said.

Larry caused widespread damage as it crossed the coast south of Cairns, with winds of up to 290km/h (180 mph). Thousands of buildings were damaged and most of the Australia’s banana crop has been destroyed. Thousands of kilometres of power lines were brought down. Many key roads are flooded.

State Emergency Service volunteers are putting tarpaulins on damaged homes. “Some homes will need complete rebuilding and that will take many months. But right now let’s get the bandaids out and get people settled as much as we can and then start the serious rebuilding of the Innisfail area.” said Kathryn Ryan, from the Disaster Management Group

Hospitals are unable to cope with the lack of clean running water and reliable power supplies. There are concerns about outbreaks of dengue fever and other mosquito-borne diseases. “Our main concern is with the quality of the drinking water, the quality of people’s food supplies and any health risks from inundation by water,” a health spokesman said.

Queensland Health Minister Jim Guthrie says there is no electricity in Innisfail, the hardest hit town in Cyclone Larry’s path. “It’s just too difficult to keep the hospital operating,” he said. “There’s no mains power but they’re also having trouble with generators – there’s a lack of fuel.”

The region’s banana, sugar cane and avocado farm industries will need rebuilding. Jan Davis, of fruit growers’ group Growcom, says Cyclone Larry will have widespread effects on the fruit industry.

Among supplies flowing in were nearly 10,500 gallons of water and 6,000 in-flight meals provided by Qantas. Troops also set up a water purification unit, and health authorities warned residents to boil their water. “There most certainly would be around 7,000 people … that are effectively homeless,” Federal Minister Bob Katter told The Associated Press. “They’re sitting in four walls but no roof.” Some 17,000 homes were blacked out in Cairns.

Ergon Energy Regional services manager Geoff Bowes says generators have been sent to Innisfail to provide power for sewerage works and some supermarkets and extra staff have been flown in from Brisbane and Townsville. “Nothing could prepare us for this,” he said.

The Australian reports that building industry and government sources have estimated the cost of Larry as “one of Australia’s most costly natural disasters, with a damage bill expected to exceed $1.5 billion.”

So far there have been no deaths or major injuries reported. Forecasters have warned of more wild weather for Queensland, with a second cyclone expected to approach the coast later this week. The Bureau of Meteorology say Tropical Cyclone Wati is moving towards the west-northwest at 13 km per hour and should gradually intensify over the next 24 hours.

A robotic system at Stanford Medical Center was used to perform a laparoscopic gastric bypass surgery successfully with a theoretically similar rate of complications to that seen in standard operations. However, as there were only 10 people in the experimental group (and another 10 in the control group), this is not a statistically significant sample.

If this surgical procedure is as successful in large-scale studies, it may lead the way for the use of robotic surgery in even more delicate procedures, such as heart surgery. Note that this is not a fully automated system, as a human doctor controls the operation via remote control. Laparoscopic gastric bypass surgery is a treatment for obesity.

There were concerns that doctors, in the future, might only be trained in the remote control procedure. Ronald G. Latimer, M.D., of Santa Barbara, CA, warned “The fact that surgeons may have to open the patient or might actually need to revert to standard laparoscopic techniques demands that this basic training be a requirement before a robot is purchased. Robots do malfunction, so a backup system is imperative. We should not be seduced to buy this instrument to train surgeons if they are not able to do the primary operations themselves.”

There are precedents for just such a problem occurring. A previous “new technology”, the electrocardiogram (ECG), has lead to a lack of basic education on the older technology, the stethoscope. As a result, many heart conditions now go undiagnosed, especially in children and others who rarely undergo an ECG procedure.

Scottish police have arrested a man and a woman after finding Britain’s largest ever stash of Gamma-butyrolactone. The man in charge of the operation, Graeme Pearson, director of the Scottish Crime and Drug Enforcement Agency, called the find “the most significant discovery of the drug in the UK.”

Denise Caron MacPherson, 45, and Hanan Rabin, 53, have been charged with exporting the drug, also known as GHB, to the United States between 19 April and 24 May. The news of the Scottish factory comes as a US study found drug use was involved in two-thirds of sex attacks, while 5 per cent were given an actual “date rape” drug.

Graham Rhodes for The Roofie Foundation, a helpline for victims of drug rape, said: “I am very relieved this has been recovered as in the wrong hands it is very dangerous. Not only is it used to spike the drinks of people to rape them but it’s also used to assault and rob people.”

Used by ravers, robbers and bodybuilders, the base chemical (gamma-hydroxybutyrate) was taken during a raid on a house and business in West Lothian. The haul would have been put on the United States illicit drug market and sold for fun and more sinister purposes.

In its non-powder form GHB is barely detectable: clear and having no smell it can be particularly potent with a few drops mixed into an alcoholic drink. Once a sufficient amount of the salty liquid has been ingested the victim can be knocked out within an hour.

While GHB is known both as “liquid ecstasy” and the date rapist’s “Plan A”, the versatile compound is also used by body builders instead of anabolic steroids, by dieters and as a sleeping aid.

In Britain, GHB is a “Class C” drug which means making it, holding it and selling it is punishable with up to two years in prison. The effects of rape, for which the drug is reportedly used, can last a lifetime. Jane Cumming, from support group Crisis, said she received an average of 4 calls a week from people claiming to be victims of date rape.

The pair, who were caught in Livingston, were accused of distributing the drug in Scotland from MacPherson’s house around the same time as they were exporting to the United States, while MacPherson was also charged with Cannabis possession.

The Internet group Anonymous today held further protests critical of the Church of Scientology.

The global protests started in Australia where several hundred protesters gathered at different locations for peaceful protests.

In a global speech, the Internet protest movement said Scientology “betrayed the trust of its members, [had] taken their money, their rights, and at times their very lives.” The protesters welcomed the public interest their protests have led to, and claimed they witnessed “an unprecedented flood of Scientologists [joining] us across the world to testify about these abuses.” The group said it would continue with monthly actions.

In a press statement from its European headquarters, Scientology accused the anonymous protesters of “hate speech and hate crimes”, alleging that security measures were necessary because of death threats and bomb threats. This also makes the Church want to “identify members” of the group it brands as “cyber-terrorists”.

Wikinews had correspondents in a number of protest locations to report on the events.

Anonymous states that the next protest is scheduled to take place on April 18, which happens to be the birthday of Suri, the daughter of Tom and Katie Cruise.

London, England — In an interview with Samoa’s Chef de Mission at the London Paralympics, Julie Tuala said she hopes to get a powerlifting program under way in Samoa following the London Games.

The Samoa Paralympic Committee, she explained, with assistance from the Oceania Paralympic Committee is submitting a grant request to acquire the equipment necessary for a powerlifting program in Samoa; equipment costs around A$18,000 to A$20,000 used, and is specifically built for paraplegic competitors who need to be strapped down when lifting. If Samoa is successful in getting the money for the equipment, the next challenge will be finding money to cover the cost of freighting it to Samoa. Tuala and the nation’s athletics coach have previously held raffles, run events at a golf club, and run bake sales to assist in covering costs for developing disability sport in the country and look to do it again if they can get the grant. The last grant the International Paralympic Committee gave for the region for the equipment did not include Samoa.

According to Tuala, equipment costs are a major barrier to participation in the development of disability sport. Samoan London Paralympian Leitu Viliamu needs a new leg as she has outgrown hers. A high quality leg like the one worn by Oscar Pistorius can cost upwards of AUD$10,000 per leg. Viliamu and fellow Samoan Paralympian Milo Toleafoa only acquired real running shoes for the first time when they arrived in London.

Samoa has primarily sent athletics competitors to past Paralympics because of the cost factor.

Nick Bos, of the University of Helsinki, studies “the amazing adaptations social insects have evolved in order to fight the extreme parasite pressure they experience”. In a recently-accepted Evolution paper Bos and colleagues describe ants appearing to self-medicate.

The team used Formica fusca, an ant species that can form thousand-strong colonies. This common black ant eats other insects, and also aphid honeydew. It often nests in tree stumps or under rocks and foraging workers can sometimes be spotted climbing trees.

Some ants were infected with Beauveria bassiana, a fungus. Infected ants chose food laced with toxic hydrogen peroxide, whereas healthy ants avoided it. Hydrogen peroxide reduced infected ant fatalities by 15%, and the ants varied their intake depending upon how high the peroxide concentration was.

In the wild, Formica fusca can encounter similar chemicals in aphids and dead ants. The Independent reported self-medicating ants a first among insects.

Bos obtained his doctorate from the University of Copenhagen. He began postdoctoral research at Helsinki in 2012. He also runs the AntyScience blog. The blog aims to help address “a gap between scientists and ‘the general public’.” The name is a pun referencing ants, its primary topic, science, and “non-scientific” jargon-free communication. He now discusses his work with Wikinews.

((Wikinews)) What first attracted you to researching ants?

Nick Bos Me and a studymate were keeping a lot of animals during our studies, from beetles, to butterflies and mantids, to ants. We had the ants in an observation nest, and I could just look at them for hours, watching them go about. This was in my third year of Biology study I think. After a while I needed to start thinking about an internship for my M.Sc. studies, and decided to write a couple of professors. I ended up going to the Centre for Social Evolution at the University of Copenhagen where I did a project on learning in Ants under supervision of Prof. Patrizia d’Ettorre. I liked it so much there I ended up doing a PhD and I’ve been working on social insects ever since.

((Wikinews)) What methods and equipment were used for this investigation?

NB This is a fun one. I try to work on a very low budget, and like to build most of the experimental setups myself (we actually have equipment in the lab nicknamed the ‘Nickinator’, ‘i-Nick’ and the ‘Nicktendo64’). There’s not that much money in fundamental science at the moment, so I try to cut the costs wherever possible. We collected wild colonies of Formica fusca by searching through old tree-trunks in old logging sites in southern Finland. We then housed the ants in nests I made using Y-tong [aerated concrete]. It’s very soft stone that you can easily carve. We carved out little squares for the ants to live in (covered with old CD covers to prevent them escaping!). We then drilled a tunnel to a pot (the foraging arena), where the ants got the choice between the food with medicine and the food without.

We infected the ants by preparing a solution of the fungus Beauveria bassiana. Afterwards, each ant was dipped in the solution for a couple of seconds, dried on a cloth and put in the nest. After exposing the ants to the fungus, we took pictures of each foraging arena three times per day, and counted how many ants were present on each food-source.

This gave us the data that ants choose more medicine after they have been infected.

The result that healthy ants die sooner when ingesting ROS [Reactive Oxygen Species, the group of chemicals that includes hydrogen peroxide] but infected ants die less was obtained in another way (as you have to ‘force feed’ the ROS, as healthy ants, when given the choice, ignore that food-source.)

For this we basically put colonies on a diet of either food with medicine or without for a while. And afterwards either infected them or not. Then for about two weeks we count every day how many ants died. This gives us the data to do a so-called survival analysis.

We measured the ROS-concentration in the bodies of ants after they ingested the food with the medicine using a spectrophotometer. By adding certain chemicals, the ROS can be measured using the emission of light of a certain wave-length.

The detrimental effect of ROS on spores was easy to measure. We mixed different concentrations of ROS with the spores, plated them out on petridishes with an agar-solution where fungus can grow on. A day after, we counted how many spores were still alive.

((Wikinews)) How reliable do you consider your results to be?

NB The results we got are very reliable. We had a lot of colonies containing a lot of ants, and wherever possible we conducted the experiment blind. This means the experimenter doesn’t know which ants belong to which treatment, so it’s impossible to influence the results with ‘observer bias’. However, of course this is proof in just one species. It is hard to extrapolate to other ants, as different species lead very different lives.

((Wikinews)) Where did the ants and fungus you used come from? How common are they in the wild?

NB For ants, see above about the collection.

This species of fungus does appear in Finland, but we chose to use a different strain from Denmark (with thanks to Prof. J. Eilenberg and the laboratory technician Louise Lee Munch Larsen from the University of Copenhagen). Animals can adapt to local strains (‘local adaptation’), and just to make sure we thought it would be good to use a strain of fungus that the ants definitely did not evolve specific resistances against. This means that the reaction of the ants (to self-medicate) is very likely to be a general response, and not just against their local fungal enemies.

((Wikinews)) Are there any ethical considerations around exposing ants to toxins and parasites?

NB Legally, no. Insects do not have any ‘rights’ as such regarding ethics. That said, we do take measures to not make them ‘suffer unnecessarily’. For example, dissections are done when the ants are anesthetized (either by CO2 or Ice), and when ants need to be killed, we do it in alcohol, which kills the ants in a matter of seconds. So while the ants do not have ‘rights’ as such, we still try to handle them with as much respect as possible (even though the experiment involves infecting them with a deadly fungus).

But even though the 12,000 ants in our study sounds like a lot (and it is), this is negligible in the ‘grand scheme of things’. It has been calculated that in the Netherlands alone, nearly a trillion insects die against just the licence-plates of cars every six months. I don’t own a car, so that means I’m excused right? 😉

((Wikinews)) This is the first evidence for self-medicating insects. How widespread do you think this phenomenon could be in reality?

NB It’s not actually the first evidence for self-medication in insects. Moths and fruit flies definitely do it, and there’s evidence in honey bees and bumble-bees as well. So it seems to be quite wide-spread in the insect world. I have no doubt that as time goes on, there will be more and more cases documented. Insects (and animals in general) seem to be quite good at taking care of themselves.

((Wikinews)) How might ants locate healing substances in the wild?

NB Very good question. This is something that’s important to know. If they would only do it in the lab, the behaviour wouldn’t be very interesting. We have some guesses where they might get it from, but at the moment we don’t know yet. That said, I plan to investigate this question (among others) further [in] the next couple of years.

((Wikinews)) For your PhD you researched ants’ scent-based communications. Could healthy ants perhaps tell other ants are infected and encourage this behaviour?

NB There’s not much known about this. There’s conflicting evidence about whether sick ants actually smell different from healthy ones or not. At the moment it seems that sick ants mostly take care of the problem themselves. Sick ants stop most interaction with nestmates and especially brood, and leave the nest to die in isolation. This is probably for reducing chance of infecting nestmates, but of course it also reduces the work load of their nest-mates, as their corpse doesn’t have to be dragged out etc.

So as an answer to the question, I would find it unlikely that such a behaviour would evolve, but it’s not known yet.

((Wikinews)) Ants generally avoided the peroxide if they were healthy, but in some circumstances might they try to build resistance against infection in advance?

NB Who knows? Also not known yet unfortunately. That said, there is a very interesting study about resin collection in ants. Wood ants collect tree-resin, which has anti-microbial properties. They collect this even if not infected, and when you infect them, they don’t collect more of the resin than normal. So basically it seems like they collect it in order to keep diseases out of the nest, so they stop the disease before it can actually infect them.

((Wikinews)) Are there plans to follow this research up? Might you research other species? Other substances?

NB I first want to find out where they get it from in nature. There might be many sources of medicine (recent evidence suggests that tobacco plays a similar role for bumble bees). Dalial Freitak, who is also on this paper is currently running tests with Ph.D. student Siiri Fuchs (who is also on the paper) with other substances to see if any have the same effect as H2O2 [hydrogen peroxide].

Once the behaviour has been well described in this species of ant, I might do a comparison with other species. For example, once we find the source of the medicine in nature… would species without access to this source also have evolved the same behaviour in the lab? And if so… where would they get it from?

Also… can ants medicate their friends? 🙂

((Wikinews)) What other research are you working on right now?

NB Phew…lots! 🙂

I still have some questions left unanswered from my Ph.D. work related to how ants recognize who is a friend and who isn’t. I also started collaborating with Prof. Michael Poulsen from the University of Copenhagen on immunity in fungus-growing termites, as well as their chemical recognition abilities. Furthermore we’re working on social parasitism in wood-ants (ants have lots of animals exploiting the nest for shelter and resources, which all somehow have to get in to the fortress without getting killed).

The Canadian PM Stephen Harper spoke with astronaut Steve MacLean over the phone yesterday from Ottawa. MacLean was on the STS-115 (space shuttle Atlantis). He is also the second Canadian to walk in space.

Harper congratulated MacLean and asked him questions, including one from Harper’s son, Ben. The question was: “What time do the astronauts go to bed?” “On our mission, with where the sun is, we have 55 minutes of daylight followed by 75 minutes of darkness … and that does affect your circadian rhythm,” MacLean replied. The astronauts’ sleep pattern “is driven by the rendezvous that we do with the station. That time is the key milestone and then we arrange our sleep schedules around that.” “But you can tell your son that sleeping in space is wonderful. We all sleep down on the main deck, some of us right side up, some of us are on the side and some of us are upside down. There’s more orientations up here, basically.”

Harper told MacLean that the country is proud of his achievements. “I’m sure it’s an adventure of a lifetime and … I expect your mission will inspire millions of Canadians, young people, and even some who are talking to you today to become interested in space and science and technology,” Harper said.

Harper wished MacLean well as the mission winds down. “I know you said … you wanted to bring home a gold medal for Canada, from everything I’ve seen on your performance yesterday, you are well on your way,” Harper said.

Canadian school children also got a chance to ask MacLean about his time aboard the shuttle.

MacLean walked in space on Wednesday. MacLean, with fellow Atlantis crew member Dan Burbank started their six-hour spacewalk at the international space station at 5:05 am ET. They are focusing their attention and tools on a ferris-wheel-like rotary joint that will allow two solar arrays, once unfurled, to always face the sun as the space station circles Earth. The solar arrays will supply a quarter of the space lab’s power when it is completed by 2010.

London, England — When Wikinews interviewed Oceania Paralympic Committee (OPC) President Paul Bird, the day before the start of this year’s Summer Paralympics, he shared the idea that whilst Oceania may not be the first place one thinks of in connection with “Paralympics” or even “developing countries”, Oceania is represented at the Games in London by athletes who have overcome many obstacles in order to compete.

According to Bird, two athletes from Oceania are regarded as medal prospects. One, Fijian high-jumper Iliesa Delana, missed out in Beijing due to his event being cancelled. He is currently ranked number two in the world, having won silver at the World Championships. The other is Francis Kompaon, a sprinter from Rabaul in Papua-New Guinea competing in the 100 and 200 metre sprints. These athletes qualified under the standard Paralympic processes. Other Oceania athletes are “wildcards”, selected by the International Paralympic Committee (IPC) to broaden the number of nations taking part. Countries do not always get their preferred choices of wildcards; for a variety of reasons, the IPC may select a less-favoured athlete. In particular, women are more likely to be chosen to address the games’ gender imbalance.

It’s not easy being an athlete, or an official, from a developing country says Bird. Often people are confronted with a host of unfamiliar situations. For example: many of the required forms are now online; officials with little technology experience have to navigate an unfamiliar landscape of browsers, buttons and passwords.

The OPC consists of eight countries: Australia, New Zealand, Fiji, Samoa, Tonga, Vanuatu, the Solomon Islands, and Papua-New Guinea. Papua-New Guinea and Samoa are sending two athletes each to the London Games. Fiji, Tonga, Vanuatu, and the Solomon Islands are sending one each.

Bird says, in attempting to promote Paralympic sport in Oceania, the region’s Paralympic Committee puts a priority on training local officials, coaches and classifiers. This helps member countries conduct their own events, without assistance from Australia and New Zealand. Additionally, the Committee organizes the Arafura Games, a regional competition.

Countries in the region are encouraged by the OPC to assemble teams, get athletes into work rankings, and plan ahead for the 2016 Paralympics to be held in Rio. Efforts are being made to strengthened ties between the region and international bodies such as the International Tennis Federation.

Bird, as head of the OPC, has been a member of the Australian Paralympic Committee since 1993. He won gold and silver medals in swimming at the 1984 Paralympics where he was the Australian Team Captain. He was the Australian Chef de Mission in Sydney in 2000 and Athens in 2004, and the Assistant Chef de Mission in Barcelona in 1992, Atlanta in 1996, and Beijing in 2008. He also currently sits on the Australian Paralympic Committee’s board.
