Friday, August 19, 2005The Australian Federal Government has revealed today that it is going to give A$21 million (US $15.76 million) as compensation to approximately 600 former RAAF maintenance workers, who where exposed to highly toxic chemicals while working on the fuel tanks of the nation’s F-111 fleet.

Under the government’s proposal, depending on the amount of exposure, a worker can expect to receive between A$10,000 and A$40,000 (US $7,500 – $30,000) to help cope with the side effects. The aircraft maintenance program started in the 1970s and was suspended in the late 1990s when the former workers started to show signs of medical problems ranging from memory loss to neurological problems.

The F-111 Deseal/Reseal Support Group responded to the government’s package with anger. The Group’s president Ian Fraser said “A$40,000 for a ruined life is simply not enough … We’ve already got people who have died, who are dying, people who have lost their homes.”

He went on to describe that his group, which supports the workers and contractors who where based at Amberley Air Base, was “at war” with Veterans’ Affairs Minister De-Anne Kelly.

Dogs can be trained to detect early and late stages of lung and breast cancer accurately according to a study published by California scientists in the little-known scientific journal Integrative Cancer Therapies.

The study took place over the last five years at the Pine Street Foundation, a non-profit organization which conducts evidence-based research on integrative medicine (combining complementary and alternative medicine and mainstream medicine). Michael McCulloch and colleagues used three Labrador Retrievers and two Portuguese Water Dogs, both common pets, that received basic behavioral dog training. The researchers trained the dogs to lie down next to a sample from a cancer patient and to ignore other samples.

The samples used were breath samples from 55 patients with lung cancer and 31 with breast cancer — the two types of cancer with the highest mortality rates in the United States.

After the training phase, the dogs’ accuracy diagnosis was tested in a double-blind experiment. Among lung cancer patients, the sensitivity and specificity were 99% accurate and for breast cancer sensitivity was 88% and specificity 98%. Because these figures seem almost too good to be true, cancer experts are the same time baffled and skeptical. The authors of the study themselves also say replication of the study is needed.

Importantly, this was independent of the cancer stage, meaning the dogs were able to pick up the scent of cancer in its early stages. This is important because in many cases, the success of any treatment depends on early diagnosis. However, the researchers don’t believe this will lead to the use of dogs in the clinic soon, rather they want to find out which chemicals are actually sensed by the canines, because they could be used in laboratory assays. “It’s not like someone would start chemotherapy based on a dog test,” Dr. Gansler of the American Cancer Society said, “They’d still get a biopsy.”.

The researchers were inspired by anecdotal reports about dogs detecting cancer. In 1989, a British women consulted with her family physician because her Dalmatian kept licking a mole on her leg. At biopsy it showed to be malignant melanoma. When diagnosed too late this form of cancer has a poor survival rate, but in this case early surgery was made possible, and the women survived. Prior studies showed that breath samples from patients with lung cancer or breast cancer contain distinct biochemical markers. This provides a basis for the hypothesis that some cancer types produce volatile chemicals that dogs could smell. A study published in the British Medical Journal already proved that dogs could use their exquisite sense of smell to detect bladder cancer in urine samples, but they were only correct in 41% of cases, and another study provided preliminary evidence that dogs could detect melanomas.

This doesn’t mean you can show your breasts to your dog and it will tell you if you have cancer, other physicians caution, and scientists do not advise people to train their dogs to sniff for cancer. Unresolved issues from the study include the fact that subjects were required to breathe deeper than normal, so it’s not sure whether dogs can smell cancer in normal breath. Also, whether this is a permanent skill that would be retained by dogs was not tested.

Finally, there are concerns that could arise over liability issues: who would be responsible when the dog makes a mistake?

Current detection methods for both lung and breast cancer are not flawless. For lung cancer, chest X-ray and sputum cytology (detecting cancer cells in coughed up fluid) fail to detect many early cases, and CT scan produces many false-positive results unless combined with expensive PET scans. Although it might be comparing apples and oranges, a $2.5 million CT scanner has an accuracy of 85 to 90%. Mammography also produces false-positive results, and it may be difficult in women with dense breast tissue. As such, another type of “pet”-scan, using dogs as a biological assay, might prove feasible for screening if supported by further research. Current tests are also expensive so the use of dogs for preliminary cancer testing could prove to be an affordable alternative for countries in the developing world.

The Marussia F1 team’s test driver, Spaniard María de Villota, was taken to hospital by air ambulance today after a collision in testing at Duxford Aerodrome.

At the end of her first installation run, the car she was driving had a low-speed collision with the loading ramp of the team’s support truck. According to BBC Cambridgeshire presenter Chris Mann, the car “suddenly accelerated” into the rear of the vehicle. The Marussia team released a statement an hour and a half after the accident, stating that she had been transferred to hospital, and a further statement would be issued once her condition had been assessed.

A spokesman for the East of England ambulance service, Gary Sanderson, said de Villota had “[…] sustained life-threatening injuries and following treatment at the scene by paramedics, she has been taken to Addenbrooke’s Hospital for further care.” According to witnesses, she was motionless for about fifteen minutes as medical teams attended to her, but did move her hands before being taken away from the test track. Medical charity Magpas, whose volunteer paramedics attended the accident, reported she had sustained injuries to her head and face, and was in a ‘stable condition’ when she reached the hospital.

Marussia reported her as conscious later in the afternoon: “Since Maria’s arrival at the hospital at approximately 10.45am this morning, she has been receiving the best medical attention possible at the hospital, which is the region’s major trauma centre. Maria is conscious and medical assessments are ongoing. The team will await the outcome of these assessments before providing further comment. The team’s first priority at this time is Maria and her family.”

De Villota was announced as Marussia’s test driver in March, having prior experience driving for Alan Docking Racing in Superleague Formula in Spain.

Actor Matt Smith will be the next to portray the Doctor on the BBC television program Doctor Who. Smith will be the eleventh incarnation of the Doctor, taking over from actor David Tennant who will end his time with the series after filming four editions of the program through 2009. The Doctor comes from a race of Timelords, and has the ability to “regenerate” and change appearance when his health is failing. William Hartnell was the first actor to play the Doctor, from 1963–1966. Smith will become the new occupant of the Doctor’s time machine and spacecraft the “TARDIS” in 2010.

John Harper, founder of the Scarborough and Ryedale Astronomical Society and a fan of the series, called the decision to cast 26-year-old Smith in the role “wonderful”. MP for Scarborough Robert Goodwill, also a fan of the program, told the Scarborough Evening News: “David Tennant will be a very hard act to follow, but I’m optimistic that the new Doctor will be just as good.”

Matt Smith, 26, portrayed researcher Danny Foster on the political drama Party Animals, which aired on BBC Two in 2007. Fellow actor Andrew Buchan from Party Animals told The Guardian: “It’s a sublime bit of casting. He’s got that huge hair, a twinkle in his eye — Matt’s the king of geek chic. He is possibly going to be one of the best Doctors we’ve ever had.”

After a back injury got in the way of Smith’s goal of becoming a footballer, his drama teacher Jerry Hardingham at Northampton School for Boys encouraged him to pursue acting. Though Smith did not audition, Hardingham cast him in a school production of the play Twelve Angry Men. Hardingham later convinced Smith to join the National Youth Theatre, and he landed the lead role in the play Murder in the Cathedral, performing before members of the British Royal Family and other VIPs at the Westminster Cathedral.

David Tennant, 37, has portrayed the Doctor on Doctor Who since taking over for Christopher Eccleston in 2005. A major feature of his character’s stories involved a romantic interest in his companion in the TARDIS, Rose, played by actress Billie Piper.

Tennant announced his exit from the program on October 29, 2008, at the National Television Awards in the United Kingdom, during his speech accepting the outstanding drama performance award at the program. Doctor Who was recognized with the award for most popular drama program.

“I love this part, and I love this show so much that if I don’t take a deep breath and move on now I never will, and you’ll be wheeling me out of the Tardis in my bath chair,” said Tennant in his address to the audience in attendance at the Royal Albert Hall. He was previously recognized at the National Television Awards for his role in Doctor Who with the award for most popular actor, in 2006 and 2007.

Tennant is currently performing the lead role in Hamlet with the Royal Shakespeare Company, and his engagement at the Novello Theatre in Westminster, London is set to end on January 10. He portrayed Hamlet 60 times with the Royal Shakespeare Company in Stratford-upon-Avon prior to the production’s move to London.

A group of researchers published a paper about their discovery of a new species of Madagascar mermaid skink lizards last December. The species is the fourth forelimbs-only terrestrial tetrapods species known to science, and the first one which also has no fingers on the forelimbs.

The species was collected at Marosely, Boriziny (French: Port-Bergé), Sofia Region, Madagascar. The Sirenoscincus mobydick name is after the existing parent genus, and a sperm whale from the 1851 novel Moby-Dick by Herman Melville.

This week, Wikinews interviewed one of the researchers, French zoologist Aurélien Miralles, about the research.

((Wikinews)) What caused your initial interest in Madagascar lizards?

Aurélien Miralles: Well, I would say that since I am a child I am fascinated by the biodiversity of tropical countries, and more especially by reptiles. I did a PhD on the evolution and systematics of skink lizards from South America. Then, I get a Humboldt grant to do a postdoc in Germany, at the Miguel Vences Lab, in order to study Malagasy skinks. Madagascar being a fabulous hotspot for reptiles (and not only for reptiles actually), it was a very nice opportunity. Professor Vences proposed me to associate our complementary fields of expertise: he is expert in herpetology for Madagascar, and I am expert in skinks lizards (family Scincidae). It was a very fruitful experience, and many other results have still to [be] published.

((WN)) How was the new species discovered?

AM: By a very funny coincidence actually. In 2010, I went to Madagascar for a long trip through the south of the island, in the semi-arid bush for collecting lizards and snakes samples. Then, during the last days, just before coming back to Germany, I have visited by coincidence the zoological collection of the University of Antananarivo. In that place, I found an old jar of ethanol with two weird little specimens previously collected by a student who didn’t realize it was something new. Being expert on skinks, I immediately recognised it was something very probably new, very different from all the other known species.

((WN)) What does “Sirenoscincus” stand for?

AM: I am not the author of the genus name Sirenoscincus. This genus name was already existing. It has been described by Sakata and Hikida (two Japanese herpetologists). “Sireno” means mermaid. “Scincus” means skinks, a group of little lizards on which I am particularly focusing my studies. So, Sirenoscinus means “mermaid skink”, in reference to [the] fact it has forelimbs but no hindlimbs.

((WN)) How deep underground do the lizards live?

AM: Hard to answer this question because nothing is known on the ecology of this species. But more reasonably, we can hypothesize, by comparison to similar species of skinks, that it is probably living just under the sand surface, [a] few centimeters deep, probably no more, or below [a] rock, leaf litter, or piece of dead wood.

((WN)) What do the lizards eat?

AM: Again, by analogy, I would say most likely small invertebrates (insects, larvae, worms etc…).

((WN)) What equipment was used during the research?

AM: Classic equipment (microscope) and also a state-of-the-art device: a micro CT-scan. It is a big device producing [a] 3D picture of the internal structure without damaging the specimen. It is actually very similar to the scanner used in human medicine, but this one is specially designed for small specimens. Otherwise, I am currently studying the DNA of this species and closely related species in order to determine its phylogenetic position compared to other species with legs, in order to learn more about the evolutionary phenomena leading to limb loss.

((WN)) There are several news sources that have a photo of the species. Is it a photo as seen in a CT-scan?

AM: No, this picture showing a whitish specimen on a black background is not a CT-scan. It is a normal photograph of the collection specimen preserved in alcohol (the one that was in the jar). You can see the complete of picture (including CT-scan 3D radiography, drawing…) in the original scientific publication.

((WN)) Do you know when the newly discovered mermaid skink species was put into the jar? Do you have its photo (of the jar)?

AM: No, I have no picture of the jar. The specimen has been collected in November 2004.

((WN)) What were the roles of the people involved in the research? What activity was most time-consuming?

AM: As first investigator, I did most of the work…and the longest part of the work was to examine closely related species in order to do comparisons…and also to check the complete bibliography related to this topic and to write the paper.

Mrs Anjeriniaina is the student who […] collected the specimen a couple of years ago.

Mrs Hipsley and Mr Müller learnt me how to use the CT-scan, and helped me concerning some point relative to internal morphology. Mr Vences helped me as supervisors. Additionally, all of them have corrected the article, and gave me many relevant advices and corrections, thus improving the quality and the reliability of the paper.

((WN)) Did you get in touch with an external entity to get the new species officially recognised?

AM: No. In zoology, it is only needed to publish the description of a new species (and to give it a name) in a scientific journal, and to designate a holotype specimen (= specimen that will be the official reference for this species), to get this new species “officially” recognised by the scientific community. That does not mean that this new species is “correct” (it might be invalidated by subsequent counter-studies), but that means that this discovery and the new name of [the] species are officially existing.

((WN)) Are there any further plans on exploring the species habitat and lifestyle?

AM: No, not really for the time being, because ecology is not our field of expertise. But other studies (including molecular studies) are currently in progress, in order to focus on the phylogenetic position and the evolution of this species.

The U.S. Supreme Court is hearing arguments on the constitutionality of the use of lethal injection as a method for the imposition of the death penalty in the United States. Two men, Ralph Baze and Thomas Clyde Bowling Jr., who were convicted of murder in the Commonwealth of Kentucky and sentenced to death, sued the state in 2004 arguing that the use of lethal injection as a method of imposition of capital punishment violates the Eighth Amendment’s prohibition on cruel and unusual punishment.

Thirty-seven states and the Federal Government have capital punishment for some crimes, all except Nebraska (which uses electrocution) use lethal injection. The process uses three chemicals in a “cocktail”, which, by the procedures that are used to apply them to the condemned, (three injections given consecutively) allegedly “create a significant and unnecessary risk of inflicting severe pain that could be prevented by the adoption of reasonable safeguards”, their lawyers said in court papers. “Kentucky seeks to execute in a relatively humane manner and has worked hard to adopt such a procedure,” Kentucky Attorney General Gregory Stumbo has said. The state has also argued in its brief against supporting the plaintiffs’ appeal that it will lead to “an endless road of litigation. … Condemned inmates will never run out of ideas for changes to the procedures, drugs or equipment used during lethal injection.”

Baze was scheduled to be executed on January 8 after Governor of Kentucky Ernie Fletcher signed his death warrant, but the Kentucky Supreme Court suspended his execution on September 12, 2007, arguing it needed more time to examine arguments he had made in a separate appeal. He was convicted of killing Powell County Sheriff Steve Bennett and Deputy Arthur Briscoe in 1992 while the lawmen were trying to serve him with arrest warrants. Bowling was convicted of killing Edward and Tina Earley in Louisville in 1990.

According to the article on lethal injection in Wikipedia, the three chemicals used are Sodium thiopental to render the offender unconscious; Pancuronium/Tubocurarine: to stop all muscle movement except the heart, causing muscle paralysis, collapse of the diaphragm, and would eventually cause death by asphyxiation; and Potassium chloride to stop the heart. The chemicals apparently cannot be combined together as they could precipitate into a solid and be ineffective. It is argued that thiopental is a very short-term anesthetic and may wear off during the procedure, causing anesthesia awareness and excruciating pain from the effects of the other drugs.

In oral hearings today, the justices seemed skeptical that the chemical concoction causes extreme pain or that a better method was available. A lawyer for one of the plaintiffs argued that if insufficient anesthetic is given, when the inmate is given the paralyzing drug, they will experience agonizing pain, but be unable to react, and that it is even illegal in Kentucky to euthanize animals in this fashion. Some of the justices have considered sending the case back for further hearings to determine if a single barbiturate would be superior to the current method.

While the Supreme Court has examined the application of the death penalty many times over the past 40 years, this is the first time the court has reviewed the issue of the method of execution in 100 years, according to lawyers for the plaintiffs. A ruling is not expected until June. There are about 3,000 people on death row in the United States, and about 60 are executed each year. Since the case was accepted by the Supreme Court, all executions in the United States have been temporarily suspended pending the decision.

The case name is Baze v. Rees.

On Monday night, governor of the U.S. state of California Gavin Newsom signed a new US$262.6 billion budget bill for the state into law, with US$8.1 billion reserved for US$600 direct stimulus payments to Californians to aid in California’s recovery from the COVID-19 pandemic. The bill for the budget, SB 129, and the bill for the stimulus payments, SB 139, both passed both houses of the California Legislature for this fiscial year.

The payments, dubbed the Golden State Stimulus II, are set to be paid out to eligible California taxpaying residents beginning in September. To be eligible, residents must have filed a state tax return for last year, not be someone’s dependent, and must have earned no more than US$75 thousand in wages last year.

Eligible Californians would get a one-time payment of US$600, and households with dependents would receive an additional US$500. Around two-thirds of Californians are expected to get a stimulus payment, according to the governor’s office. Newsom initially proposed the payments in May to aid the state’s economic recovery, as part of his “California Comeback Plan”.

Californians who already received a stimulus payment earlier in the year are not eligible for this second payment. An additional payment of US$500 is still available for those who claimed dependents on their returns.

The budget also provides for US$5.2 billion in renters’ aid for low-income residents and landlords, which would pay for all rent left unpaid during the COVID-19 crisis, and cover rent for several coming months. Overdue water and utility payments would also be covered by US$2 billion in funding.

An additional US$1.5 billion was for grant money intended for small businesses, with US$120 million in tax credits for businesses willing to relocate to California.

California had a budget surplus of nearly US$76 billion during the COVID-19 pandemic.

In signing SB 129, Newsom line-item vetoed Section 19.55 of the bill concerning US$2.58 billion in appropriations to various funds “on a technical basis”, citing in an explanation appropriations covered under the section were superseded by the budget. In California, a governor may approve a bill passed by the Legislature with specific items related to the budget rejected. The Legislature can override this line-item veto with a two-thirds vote of both the Assembly and the Senate.
