A University of Tokyo group of researchers, led by bioengineer Shoji Takeuchi, has made an electronic sensor capable of smelling gases. The sensor uses genetically engineered frog cells. Since previous sensors were not very accurate, the scientist decided to try a biological approach. The invention was revealed in a US scientific journal yesterday, and is supposed to be used to design better machines to detect polluting gases in the atmosphere.

Previous smell sensors were based on quartz rods, which vibrate when a substance binds to them. The gases are distinguished by their molar masses, which can be similar for molecules with different structure, thus relatively often triggering a false positive. Trying to find a more accurate solution, Takeuchi decided to follow an example from insect world. As he explained, “when you think about the mosquito, it is able to find people because of carbon dioxide from the human. So the mosquito has CO₂ receptors. When we can (extract) DNA (from the mosquito) we can put this DNA into the frog eggs to detect CO₂.”

Genes of several insects (the silk moth, diamondback moth and fruit fly), injected into African clawed frog Xenopus laevis eggs, allowed them to produce relatively inexpensive and useful sensors. The choice of the species was caused by their widely studied and well-understood protein expression mechanism.

The modified cells responded to three kinds of pheromones and one odourant, which have similar chemical properties. When a molecule of an odorous substance adhered to the receptor on the membrane protein, ion channels opened for a certain period of time, and a current was generated. Its magnitude was clearly different for all four tested substances, allowing to distinguish between them accurately.

The colleagues embedded the sensor into a mannequin, so that it could shake its head when a gas was detected. It was easier to observe. Pheromones and molecules with quite similar molecule structure produced clearly distinguishable reaction, with higher accuracy than other biological or human-made sensors. As the research group said, the detection sensitivity of the odor sensor is several tens of parts per billion (ppb), and it is as high as the sensitivity of an existing odor sensor that uses an oxide semiconductor. The distinctive feature of the new sensor is its capability to selectively detect some odorous substances, rather than its sensitivity. Very few false positives were possible due to the biological mechanism involved.

At normal temperature, the sensor lifetime is about 12 hours, which can be extended by putting it into a refrigerator before first use.

Shoji Takeuchi says has a great hope for research use in future, since the frog eggs are very practical for genetic engineering, and can be conveniently used to develop smell sensors for a wide range of gases. He said, “The X. laevis oocyte has high versatility for the development of chemical sensors for various odorants. We believe that a shared ability to smell might open a new relationship between man and robot. .. The research will have wide implications… If the sensor is embedded in a nursing robot, it will be able to identify certain mouth odors or body odors. Also, it can be used for detecting CO₂, air pollution, water pollution and food. It’s very important for the environment.”

Saturday, April 23, 2005Queensland Australia’s Sir Joh Bjelke Petersen, a controversial figure who served as the State’s Premier for 19 years and reigned over the government that later became the subject of the Fitzgerald Inquiry, has died in hospital at Kingaroy, aged 94.

“By any measurement, Sir Joh was an exceptional state builder who will be remembered for consistently placing Queensland first,” said the Australian Governor General, Major General Jeffery, in a statement.

Australian Prime Minister, John Howard: “He was certainly a strong political figure and I extend my condolences to his wife and his family.”

But not all voices were sympathetic, prominent Queensland Aboriginal activist Sam Watson for example: “Aboriginal people will always remember him as a racist, a thug and a dictator.”

Having suffered severe ill-health for some weeks, and declining health for years, Sir Joh passed away at around 6pm AEST. He was surrounded by his family, who had been summoned yesterday by Lady Flo, his wife and one-time Senator, for final goodbyes.

Phrases such as “Don’t you worry about that” and “Goodness gracious me” were like trademarks to the maverick leader.

Known simply as ‘Joh’ to many, he would famously describe press conferences as ‘feeding the chooks’. Today Kingaroy locals taunted waiting press with cries from “You’re chooks, you’re chooks, ha ha” to “Go home, ya vultures”, and some obscenities, reported the Courier-Mail of Brisbane.

His fall from power at the end of the 80s was surrounded in controversy, with the state embroiled in corruption findings going to the level of his deputies, and Bjelke Petersen’s claims of ignorance coming under challenge with charges of perjury. The case was never heard due to a controversial hung jury: the foreman of the jury, Luke Shaw, had been an office-bearer of the Young Nationals — an arm of Bjelke Petersen’s National Party — as well as a member of a group calling themselves ‘Friends of Joh’.

Having had his start in life as a peanut farmer in remote Kingaroy, the former Premier was fit up until the very end, but palsy was paralyzing his muscles and organs, to which he eventually succumbed.

“Throughout his life Sir Joh combined enormous energy, vision and an immense capacity for hard work, most especially during his 19-year term as Premier of Queensland,” the Governor General said.

“What looked to us to be huge risks at the time turned out to be nation building,” said Bob Katter, a former minister of Joh’s Government, who credited Sir Joh with starting the Queensland coal, aluminum and tourism industries.

He is also remembered for dismantling many of the State’s unions, and for a somewhat totalitarian and heavy handed style of keeping control.

Under Joh, street protests were banned and Special Branch monitored extensively those the authoritarian leader saw as subversives, measures prompting Queenslander, Australian Civil Liberties Council, Terry O’Gorman, to comment Sir Joh was “the most appalling premier Queensland has ever had in terms of civil liberties and human rights”.

Joh was also influential in the famous case of the Dismissal by the Governor General of then-Prime Minister Gough Whitlam, in 1975.

In his last years as Premier, he had taken his cause to the nation’s capital, with the “Joh for PM” campaign. But this distraction has been credited with the downfall of his government, with corruption investigations at last being conducted by his stand-in, Bill Gunn.

The body of Sir Joh, who was of Lutheran faith, is to be buried at Bethany, the family property near Kingaroy.

Unsolicited quotes from ordinary Australians, many ex-Queenslanders seeking refuge in southern states, on hearing the news:

“Outrageous bastard! Oh God! That was polite!” — “Karen”

“Guilty as Hell. And that’s where he is now.” — “Michael”

“Yay! Good riddence to bad rubbish” — “Liza”

“The dictator is gone our time 2 sing” — “John. H.”

“Yeah he took a while — about 90 f*cking years overdue!” — “Hose Man”

“The pope an joh at least somethin going right” — “Helen”

“Corrupt f*cking sh*teating Bible-bashing f*ckw*t is dead. And thank f*ck. I haven’t been so happy since September 11!” — “Greg”

“I don’t drink but I’ll be having a red whilst dancing on his grave.” — “Cellest”

“Ding dong the d*ck is dead!” — anon.

“Yeahhh!!! Fucking finally” — “Leo”

“It’s a great day today the Rednecks are silent a great victory has been won” — “Zenner”

Officials arrested 41 people from five countries Sunday in connection with a trans-European money laundering operation. The individuals are suspected in laundering US$300 million in gang-related activities such as prostitution, murder, and arms and drug trafficking, according to police with Interpol and Europol.

The BBC reported citizens of Spain, France, Finland, Russia, and Ukraine were among those arrested and charged with illegally siphoning money from Yukos, a large Russian oil company. Yukos maintains it was unaware of such activities.

The crackdown went by code name Operation White Whale and was a joint effort between Spain and Russia, officials said. The arrests were centered in the Costa del Sol area of Spain’s southern Mediterranean coast.

Thursday, June 1, 2006An attack against the Rashtriya Swayamsevak Sangh headquarters in Nagpur was thwarted by the Maharashtra police early today morning. The militants were driving a white Ambassador car and were armed with AK-47s. They were confronted and killed by security forces as they tried to break through the security cordon surrounding the building.

Nagpur Police Commissioner S.P.S Yadav said that the car was chased by police after it broke through the first barrier about 200 metres away from the headquarters. When confronted, the militants opened fire and were killed after a five-minute shootout. Yadav also said that two policemen had been injured in the incident, one of whose condition was serious. The identities of the three men is yet to be established. A diary was also recovered from the terrorists.

A high level security alert has been declared in Nagpur and other sensitive areas in the vicinity. R.S.S chief Ram Madhav urged the government to take more steps to safeguard the offices of the organisation. This is the second time the police has prevented a major terror attack from taking place in Maharashtra. Last month the Anti-Terrorist Squad had recovered 30 kilograms of RDX, 17 AK-47 rifles and 50 hand-grenades from a jeep in Aurangabad. Eleven suspected militants were also arrested.

The Peace Tax Seven, who are campaigning to have the 10 per cent of their taxes which go to Britain’s defence budget diverted to non-military uses, have had their case rejected by a High Court judge.

The judicial review was called for under article 9 of the European Convention on Human Rights which guarantees freedom ‘to manifest one’s religion or beliefs’ and which was made a part of British law in 1998. The Convention includes the right to conscientious objection and the campaigners claim that this gives them the right not to pay other people to go to war on their behalf.

Their statement to the court said: “We want to make a positive contribution to society by paying our tax in full. We object in conscience to paying others to kill on our behalf, but current tax policy forces us to do just that.”

The courtroom had to be enlarged to make room for supporters and the judge listened to the case for three hours.

Roy Prockter, an accountant and campaign member as well as a Quaker, said that the judge told them that “our case has no possibility of being resolved in the British courts”. According to the Guardian, the judge suggested they take the case to Strasbourg. Roy said that the members were going to take time for reflection as they awaited the written judgment from the judge.
