American metal singer Ronnie James Dio died today at the age of 67, as announced by his wife, Wendy. Dio passed at 07:45 (CST) (13:45 UTC) at the Mayo Clinic, an American disease treatment center, after a two-year fight with stomach cancer that caused him to stop singing while he received treatment. “Ronnie knew how much he was loved by all…Please know he loved you all and his music will live on forever,” added his wife in a statement on Dio’s website.

Dio (born Ronnie James Padavona) was born in July 10, 1942 in the American city of Portsmouth, New Hampshire. He was most noted for his high pitched vocals and lyrical tales involving battles and themes of good versus evil.

He performed with several hard rock and metal groups, but he was most notable for his first act, when he joined as singer of the British metal group Black Sabbath after lead singer and frontman Ozzy Osbourne left the band in 1979. Before Black Sabbath he performed with several less successful bands, including Rainbow, led by former Deep Purple‘s Ritchie Blackmore, and Elf.

He also had a very successful solo career under the simple name “Dio”, and had recently reunited with former Black Sabbath band mates under the moniker Heaven and Hell. Some of Dio’s hit songs were Holy Diver, Neon Knights, and The Last In Line.

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).

Quiznos, a fast food restaurant chain that specializes in selling submarine sandwiches, has aired a controversial television commercial, with an extended version only appearing in the late-night lineups. The commercial is a promotion for the company’s new sandwich, the ‘Toasty Torpedo’. Bob Sassone, a writer for TVSquad.com, argues that it is homosexually themed and compares it to pornography.

The commercial begins with a toaster oven talking to Scott, a Quiznos sandwich maker, in a male voice. “Scott, I want you to do something,” says the toaster to Scott. As he takes a bite of a Torpedo and appears to look in the direction of his genitals, Scott says to the toaster, “[sic] not doing that again. That burned.” The toaster replies, “We both enjoyed that.”

Later in the commercial, the toaster asks Scott to make one of the sandwiches and says the price of it is “sexy” and then “sexier.” Scott grins and does so. The toaster then asks Scott to “stick it in me”. The sandwich just happens to be 12 inches long, giving the appearance of a special relationship between Scott and the toaster oven.

Quiznos published a press release on March 24 announcing the new line of sandwiches. They stated that their price of US$4 helps to ease the economic pinch. In a statement to Wikinews Quiznos stated that their commercials are within the company’s character and they were designed to get people talking.

“We developed our new ads to be consistent with the Quiznos brand and to get people excited about our new Toasty Torpedoes. Some of the ads are edgy and provocative, but they’re well within the confines of the Quiznos brand character,” said Rebecca Steinfort, chief marketing officer for Quiznos to Wikinews.

“Since Quiznos has a broad range of consumers that eat at its more than 4,500 restaurants nationwide, we tailor our commercials to be relevant and appeal to our diverse customers – all of whom are watching different kinds of programming. The new ads are fun and entertaining, and the edginess and innuendo of the ads are designed to get people talking about our new Toasty Torpedoes, and that’s exactly what we want: people to talk and taste our new sandwiches,” added Steinfort.

Bob Sassone a writer for TVSquad.com, one of the Internet’s top television weblogs, compared the commercial to a pornography film.

“The new Quizno’s commercial is probably the closest we’ll get to a gay porn flick in a mainstream sub shop ad,” Sassone wrote.

In 2007, the company made another controversial commercial. It featured people on the street eating samples of a Quiznos ‘Prime Rib Dinner’ sandwich. They promoted it as having a lot of “meat” and near the end it featured two women eating a sandwich saying, “It’s not lacking any meat. And that’s what real women need”.

“Nevertheless, Quiznos remains committed to providing its customers with high-quality ingredients at everyday lower prices, all with excellent service. As such, we encourage consumers to give feedback on the commercials to our corporate marketing department through the website,” said Steinfort.

In Vancouver, a 20-year urban success story may yet have a sad ending. The city’s downtown population has doubled to 80,000 in the last 20 years thanks to Vancouver’s “Living First” policy – a planning strategy that favors residential development over commercial. And planners are expecting the population to reach more than 120,000 by 2030. But while downtown booms with people, business is busting. The International Herald Tribune reports that the city’s recently-released jobs and land-use study is estimating that downtown Vancouver may run out of commercial and office space within 5 years.

The ‘Vancouver problem’ is one that many cities in the United States could only hope to have. On the contrary, much effort has been put into bringing residential life back into the city centres. In Los Angeles, San Diego, Miami, and Washington, D.C. there has been a condominium boom in recent years, but these cities are far from the situation Vancouver faces now.

To counter the trend in Vancouver, planners are proposing changes to the city’s zoning regulations, including the passage of more lenient building height restrictions. But because residential developments are so much more profitable than commercial and office space, some public officials are proposing offering better incentives to the developers willing to build commercial. Another option is to expand the moratorium that was placed on new housing development in the central business district two years ago.

Translink is currently involved in a major expansion of the 49.5 km (30.8 mi) Skytrain system centred on downtown Vancouver. Construction of the Canada and Evergreen lines is underway. The former will be complete in 2009, and the latter in 2011.

Ernest Krajniak from Chilton, Wisconsin in the United States has been charged with arson after a lit cigarette ignited gasoline soaked clothes, setting his apartment ablaze.

On Friday April 3, Krajniak, 47, cleaned his entire apartment with about five gallons of gasoline, wiping everything down with the soaked clothes. After he was finished, he piled the soaked clothes in the center of his bedroom, lit a cigarette and then threw what was left of the still lit cigarette, into the pile.

Krajniak never called the fire department and never pulled the alarm. Instead he yelled ‘fire’ a few times then walked to the police station where an ambulance took him to a local hospital for the treatment of minor burns. The fire department later arrived to put out the blaze and his apartment was extensively smoke damaged. 11 other apartments were also damaged, leaving the occupants without a place to stay for at least a week.

“I should have never used that,” said Krajniak during a court appearance on Monday. He admitted to knowing that gasoline was highly flammable. He was arrested and his bond has been set a US$2,500. Krajniak’s next court appearance is scheduled for Monday, April 13. According to WISinfo.com, Krajniak has no prior criminal record.

The careless smoking of cigarettes has been blamed for thousands of fires across the U.S. In January 2008, an unnamed elderly woman in Buffalo, New York was receiving oxygen for medical problems in her home and lit a cigarette and began to smoke it. The oxygen coming from her mask then facilitated the ignition of her clothing, setting her on fire.

In the U.S. in 2002, only 4% of all residential fires were reportedly caused by smoking materials. These fires, however, were responsible for 19% of residential fire fatalities and 9% of injuries. The fatality rate due to smoking is nearly four times higher than the overall residential fire rate; injuries are more than twice as likely. Forty percent of all smoking fires start in the bedroom or living room/family room; in 35% of these fires, bedding or upholstered furniture are the items first ignited.

New ‘deadly’ sexual enhancement products have been found in Singaporean markets and can cause serious side effects on users.

The Health Sciences Authority (HSA) announced the presence of the illegal drugs, known as Power 1 Walnut, Santi bovine penis erecting capsule, Zhong Hua Niu Bian and fake Cialis, which have been discovered over the past 3 months. Santi bovine penis erecting capsule has been found to contain high amounts of glibenclamide, a potent drug used to treat diabetes. The tablets also contain sildenafil and tadalafil – potent western medicines used to treat erectile dysfunction. Zhong Hua Niu Bian also contains sildenafil and glibenclamide.

High consumption of the tablets can be potentially deadly as the glibenclamide in the capsules can lead to drastically reduced blood sugar levels which can lead to seizures, stroke, coma or death. Consuming half of a Power 1 Walnut capsule has led to unconsciousness and frothing at the mouth.

Consumption of Power 1 Walnut has led to the death of a middle age man last week who fell into a coma. Currently, one death and two cases of coma have been reported from the total of 89 hospitalised cases linked with the consumption of the illegal drugs. It has been revealed that patients obtained the drugs by purchasing them from illegal peddlers located in various parts of Singapore.

The HSA has advised people to stop consuming the drugs and to report on any cases of consumption to them.

Journalist, counselor, painter, and US 2012 Presidential candidate Joe Schriner of Cleveland, Ohio took some time to discuss his campaign with Wikinews in an interview.

Schriner previously ran for president in 2000, 2004, and 2008, but failed to gain much traction in the races. He announced his candidacy for the 2012 race immediately following the 2008 election. Schriner refers to himself as the “Average Joe” candidate, and advocates a pro-life and pro-environmentalist platform. He has been the subject of numerous newspaper articles, and has published public policy papers exploring solutions to American issues.

Wikinews reporter William Saturn? talks with Schriner and discusses his campaign.
