Tuesday, March 29, 2005A team of Australian surgeons yesterday reattached both hands and one foot to 10-year-old Perth boy, Terry Vo, after a brick wall which collapsed during a game of basketball fell on him, severing the limbs. The wall gave way while Terry performed a slam-dunk, during a game at a friend’s birthday party.

The boy was today awake and smiling, still in some pain but in good spirits and expected to make a full recovery, according to plastic surgeon, Mr Robert Love.

“What we have is parts that are very much alive so the reattached limbs are certainly pink, well perfused and are indeed moving,” Mr Love told reporters today.

“The fact that he is moving his fingers, and of course when he wakes up he will move both fingers and toes, is not a surprise,” Mr Love had said yesterday.

“The question is more the sensory return that he will get in the hand itself and the fine movements he will have in the fingers and the toes, and that will come with time, hopefully. We will assess that over the next 18 months to two years.

“I’m sure that he’ll enjoy a game of basketball in the future.”

The weight and force of the collapse, and the sharp brick edges, resulted in the three limbs being cut through about 7cm above the wrists and ankle.

Terry’s father Tan said of his only child, the injuries were terrible, “I was scared to look at him, a horrible thing.”

The hands and foot were placed in an ice-filled Esky and rushed to hospital with the boy, where three teams of medical experts were assembled, and he was given a blood transfusion after experiencing massive blood loss. Eight hours of complex micro-surgery on Saturday night were followed by a further two hours of skin grafts yesterday.

“What he will lose because it was such a large zone of traumatised skin and muscle and so on, he will lose some of the skin so he’ll certainly require lots of further surgery regardless of whether the skin survives,” said Mr Love said today.

The boy was kept unconscious under anaesthetic between the two procedures. In an interview yesterday, Mr Love explained why:

“He could have actually been woken up the next day. Because we were intending to take him back to theatre for a second look, to look at the traumatised skin flaps, to close more of his wounds and to do split skin grafting, it was felt the best thing to do would be to keep him stable and to keep him anaesthetised.”

Professor Wayne Morrison, director of the respected Bernard O’Brien Institute of Microsurgery and head of plastic and hand surgery at Melbourne’s St Vincent’s Hospital, said he believed the operation to be a world first.

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).

American Major League Baseball third baseman Alex Rodriguez, a star player for the New York Yankees, admitted in an interview on sports network ESPN that he used performance-enhancing drugs during 2001 through 2003.

“I did take a banned substance, and for that, I’m very sorry,” Rodriguez told ESPN’s Peter Gammons. “When I arrived at Texas in 2001 I felt an enormous amount of pressure to perform.”

Last week, Sports Illustrated reported that the baseball player, nicknamed ‘A-Rod’, tested positive in 2003 for Primobolan and testosterone, two substances that have been banned by the league.

During the 2003 season, Rodriguez was playing with the Texas Rangers, and was the winner of the American League MVP Award and was American League leader in home runs. According to sources, Rodriguez was one of 104 players named on a list for testing positive before the 2003 season. The list was compiled in an attempt to determine whether the MLB needed to begin conducting random drug testing.

After the initial report Rodriguez was approached by Sports Illustrated while he was training for the upcoming season in a Miami area gym. At that time, Rodriguez told the reporter “You’ll have to talk to the union.” He was also asked for an explanation of his positive test result, to which he commented “I’m not saying anything.” According to a report by ESPN, sources claim that Rodriguez was aware that he tested positive for performance-enhancing drugs.

However, in December 2007 after United States Senator George J. Mitchell‘s Mitchell Report was released accusing such teammates of Rodriguez as Roger Clemens, Jason Giambi and Andy Pettitte of steroid use, Rodriguez appeared on ABC’s 60 Minutes and declined the use of any steroid or performance-enhancing drug. He also commented that he would not need the help of steroids, stating, “I’ve never felt overmatched on the baseball field. I felt that if I did my, my work as I’ve done since I was, you know, a rookie back in Seattle, I didn’t have a problem competing at any level.”

Senator Mitchell stated in a prepared comment yesterday that his report had only named that players that “had received credible evidence of their illegal purchase, possession, or use of performance enhancing substances.” He pointed out that he “did not have access to the results of the 2003 drug testing, and to this day I do not know which players tested positive then.”

The MLB declined to comment directly on the situation due to court orders on the list of names and documents, but did release a statement: “Information and documents relating to the results of the 2003 MLB testing program are both confidential and under seal by court orders. We are prohibited from confirming or denying any allegation about the test results of any particular player by the court orders. Anyone with knowledge of such documents who discloses their contents may be in violation of those court orders.”

Rodriguez has been one of the many prominent American baseball players over the past few years who has been linked to the use of performance-enhancing drugs. Other prominent names include both the arguably greatest hitter and pitcher in Major League Baseball history, Barry Bonds and Roger Clemens. Bonds, the all-time Major League record holder for home runs, was linked to steroid use during the BALCO scandal in 2003, while Clemens was named in the Mitchell report in December of 2007.

The executive vice president for labor relations of Major League Baseball, Rob Manfred, stated that league commissioner Bud Selig was “disturbed” by the linking of steroid use to Rodriguez. Commenting for the league, he said, “Because the survey testing that took place in 2003 was intended to be non-disciplinary and anonymous, we cannot make any comment on the accuracy of this report as it pertains to the player named.”

The report by Sports Illustrated also made the claim that Gene Orza, the COO of the Major League Baseball Players Association informed Rodriguez of a random drug test that occurred in September of 2004, a test that was supposed to remain confidential to all players. The MLBPA denied the accusations, commenting “There was no improper tipping of players in 2004 about the timing of drug tests. In September 2004 MLBPA attorneys met with certain players, but we are not able to confirm or deny the names of any players with whom we met.” When asked in the Sports Illustrated report, Orza declined to comment, stating “I’m not interested in discussing this information with you.”

The anonymous testing of players was started in 2003 by the MLB, in order to get a brief estimate of how many players were using performance-enhancing drugs, leading to the beginning of the mandatory, penalty-enforced testing that began in 2004. 1,198 players took the “survey test” in 2003, and the results were later stored in a laboratory in Las Vegas, with codes being used in place of the players names. However, a list of the players actual names that went with the list of codes was kept in a separate office in Long Beach, never intended to ever be together with the codes.

In April 2004, federal agents with search warrants raided the two labs looking for information on the 2003 BALCO scandal test results of 10 players, including Barry Bonds. While searching, they found both the list of names and the codes, including the positive test result of Rodriguez. Following the investigation and raid, the MLBPA informed all 104 players on the list that their positive test data had been sized by the federal agents.

Former Major League Baseball star and self-confessed steroid user José Canseco told the media that the news was old, saying “I said in my book Vindicated that he was a known steroid user before 2000. It’s old news. I’ve been saying this forever. You guys are playing catch-up.” In the book, Canseco links Rodriguez to steroids through the claim that he saw him using the drugs. In his first book, Juiced, references to Rodriguez were removed by the publisher of the book because it could not be confirmed that Canseco actually saw Rodriguez taking steroids. According to the publisher, it was only after Canseco passed a lie detector test that information about Rodriguez was allowed into Vindicated.

Current senior advisor to the Texas Rangers John Hart commented on the situation in an interview with MLB Network. “I think in the climate that we have today, you don’t have much shock anymore. Obviously Alex probably is the best player in baseball. This has always been a special talent and the guy has been putting up Hall of Fame numbers since the day he showed up in the big leagues. I’ve been in the game for almost 40 years and it hurts a little bit, if in fact this is true. It breaks my heart for the game that we have this kind of thing occurring, But at the same time, a lot of people seem to have been caught in this net,” he said.

Since the positive test occurred in 2003 before penalties were instituted, Rodriguez will most likely not be suspended by the MLB as a result of the situation.

On February 14, a man staying at the Valley View Extended Stay America hotel in Las Vegas, Nevada was hospitalized after experiencing respiratory distress. The man lapsed into unconsciousness and has been at the hospital ever since.

Since the bills at the hotel were going unpaid, Extended Stay America began to evict the man from the room. Another man, described as either a friend or relative, went to the hotel on Thursday to collect the personal belongings of the hospitalized man.

According to Las Vegas Metropolitan Police Department Deputy Chief Kathy Suey, he found several vials of a white substance. He brought them to the attention of the hotel manager, who called police.

Initial tests, which further tests confirmed on Friday, the substance was the deadly toxin ricin, an extremely dangerous biological agent. Ricin is extracted from castor beans through the waste produced in the manufacture of castor oil. It is currently being used in cancer treatment research. There has been research for its use as a chemical/biological warfare agent. An amount smaller than the point of a pin will kill a human being. It is estimated to be several thousand times more toxic than cyanide and there is no known antidote.

Police cordoned off the area around Valley View between Flamingo Road and Harmon Avenue. Three employees and the man who made the discovery were taken to the hospital as a precaution. So were three police officers. They are all reported to show no signs of poisoning.

Nevada National Guard and other emergency services responded to secure the area. Residents at the Extended Stay America were allowed back into the building late Thursday. The hotel reopened fully on Friday after the room and other areas of the hotel were decontaminated.

The man whose room it was “is in critical condition and he is unable to speak with us right now. We have no indication why the ricin was in that room,” said Deputy Chief Suey.

“Usually, if [ricin victims] survive the first three to five days, they usually do fine,” Dr. Lawrence Sands told CNN. However, survivors often have long-term organ damage.

At least three pets were found in the room. “Two of those pets are fine. One of the pets is deceased or was put down,” Suey said. “The dog that was in there was without food and water for a week,” she added that there was no reason to supect it was exposed to ricin. Castor beans were also found in the room.

Officials have also recovered from the room a firearm, as well as an “anarchist” text containing an article on ricin.

Federal Bureau of Investigation spokesperson Richard Kolko said the incident is being treated as a criminal matter and did not appear to be related to terrorism “based on the information gathered so far.”

Captain Joe Lombardo of the Las Vegas Metropolitan Police Department said that ricin is not illegal to own unless it is intended for the poisoning of a person, adding that “We did have enough ricin to be of concern.”

In 2003, a man committed suicide in Las Vegas using ricin. There have also been a few incidents where ricin powder was found in the mail. Also in 2003, the United Kingdom had the Wood Green ricin plot which in the end found no ricin.

In 1978, Bulgarian defector Georgi Markov was famously assassinated in London with ricin injected with the tip of an umbrella.

At least five to ten police officers in Afghanistan have been killed and at least 11 others were wounded after a suicide bombing in the southern part of the country in the town of Spin Boldak at a checkpoint.

Police officers were having lunch inside a room at the checkpoint when the bomber, who was also dressed in a police officer’s uniform, walked in and detonated his explosives. At least two rooms were destroyed, according to police.

“We were eating lunch around 1330, when a suicide attacker wearing police uniform entered the post and blew himself up,” said Bismillah Khan, commander of the local police in Spin Boldak who could only confirm that “five border police are killed and 11 are injured.”

No one has claimed responsibility for the attack.

A compilation of brief news reports for Thursday, June 14, 2007.

A bomb blast during a soccer match at stadium in Pattani injured 14 police officers who were providing security for the game between two local teams.

Police said the bomb was placed inside a flower planter and detonated via cellphone, and that five officers were seriously injured.

This past Sunday, Illinois Governor Pat Quinn signed into law a bill known as “Rocky’s Law” that requires Illinois high schools, through the local school district, to buy catastrophic injury insurance up to US$3 million or medical costs for up to five years, whichever one comes first, that covers student athletes. The insurance must cover student athletes while they are competing.

The legislation was named after Rasul “Rocky” Clark. In 2000, the Eisenhower High School football player became paralyzed from the waist down as a result of a tackle during a game. His school based health insurance covered the costs of his medical treatment. A legislator sponsoring the bill noted that the need for this type of insurance is rare. Clark’s mother attended the legislation signing. Her son died last year.

Before parents can claim money from school insurance, they first must pay out US$50,000. Schools have until January 1, 2014 to comply with the law. Schools cannot charge students more than US$5 to defray the cost of insurance. If a school district already requires student to be covered through private health insurance, they are exempted from this law.
