Compound that leaves its traces in smoker’s breath for 72 hours found

Washington, May 21 (ANI): A team of Catalan researchers has discovered the presence of a compound called 2,5-dimethylfuran, which lingers in a smoker’s breath for 3 days.

This substance does not appear in the breath of non-smokers, unless they have been in direct contact with tobacco smoke for a long time. However, it may be detected in a passive smoker if he or she has been in direct contact with smoke for a long time.

“2,5-dimethylfuran cannot be detected in breath samples of non-smokers, meaning that the only way to know if a person has smoked in the last 72 hours is to use its qualitative determination”, Juan Manuel Sánchez, researcher with the Chemistry Department of the University of Girona (UdG) and co-author of the study, reports to SINC.

“Benzene, which is sometimes appears in the bibliography, is only useful when tobacco consumption is relatively high and in short periods –between 1 and 2 hours– after having smoked a cigarette, which means it is of no use from a practical point of view”, explains Sánchez.

To prove their theory, the researchers collected breath samples of 100 smokers and 104 non-smokers, who were first asked to answer a questionnaire on their habits.

The results confirm that the presence of 2,5-dimethylfuran is associated with the act of smoking.

The study appears in the journal Analytical and Bioanalytical Chemistry. (ANI)

Pak civilian arrested in Chile denies illegal possession of explosives

Santiago, May 20 (ANI): Saifur Rehman Khan, the Pakistani civilian who was detained after traces of explosives were detected on him at the US Embassy in Chile, has denied all charges being labelled against him.

Saifur, who was released after charges of illegal possession of explosives were labelled against him, appealed to the US authorities to trust him, saying he was not involved in any wrongdoing.

“I have friends and family in the US and more than anyone I want America to be safe and secure. I have been to the US and I greatly admire the American values of truth, justice and freedom,” a statement released by him stated.

“As my defence pleaded, the panic appears to have stemmed from a false alarm… Please, have your trust in me. I have no knowledge of any substance that can cause harm to anyone. I wish the perpetrators of violence are caught,” The Daily Times quoted Saifur, as saying.

Saifur described the whole controversy as part of a ‘big misunderstanding’, which was could have been a result of some kind of ‘mistaken identity.’

Traces of Tetryl, a compound used as a booster to help detonate explosives, was found on documents and the mobile phone recovered from Saifur, while he was trying to enter the US Embassy in Chile. (ANI)

Pak man arrested in Chile charged for illegal possession of explosives

London, May 16 (ANI): The Chile Government has charged Muhammad Saif-ur-Rehman Khan, a Pakistani student arrested at the US Embassy in Chile, for having traces of volatile material, with illegal possession of explosives.

Police said traces of Tetryl, a compound used as a booster to help detonate explosives, was found on documents and the mobile phone recovered from Khan, who was arrested on Monday, The BBC reports.

However, Khan has denied any wrongdoing and has been freed pending an investigation.

Earlier, he had blamed the US for his arrest and bringing unnecessary trouble for his family back home in Pakistan.

“I have nothing to do with bombs. I have nothing to do with terrorists. I don”t have a beard. They (the US) just want to cover up their shame and guilt for what they have done or are doing in Iraq and Afghanistan,” he had told media persons just after being detained.

Khan’s father, Mehmood Ahmad Rehman Khan, had alleged that his son has been implicated in a trap, and made a victim of racial profiling.

“My son became a victim of racial profiling and has been detained without a valid reason or evidence. His arrest was clearly a setup,” Mehmood had said earlier. (ANI)

Panel defends water report delay

The panel investigating water quality concerns in Tasmania’s north-east has defended the delay in making the results of the investigation public.

St Helens GP Alison Bleaney was the first to raise concerns about the quality of water in the George River.

She conducted her own tests of the water and says they reveal traces of a toxin found in some tree plantantions.

The convenor of the State Government-appointed George River Water Quality panel, John Ramsay, says Dr Bleaney’s report will be made public at the same time as other relevant reports.

“The investigation is progressing well, but there are a lot of documents to get through,” he said, “some 38 documents from the Department of Primary Industries, Water and Environment, 45 documents from the Department of Health and Human Services.”

The information will be posted on the panel’s website when it reports to the Government at the end of the month.

Detained Pak youth’s father alleges his son’s arrest in Chile a ‘racial profiling trap’

Islamabad, May 13 (ANI): Father of Saif-ur-Rehman, the Pakistani man who was arrested in Chile on charges of entering the US Embassy with traces of explosives on his clothes, has alleged that his son is being implicated in a trap, and has been made a victim of racial profiling.

Mehmood Ahmad Rehman Khan said his son, who is doing an internship in a hotel in Chile, had received a phone call asking him to appear for an identification check at the US Embassy in Santiago.

He claimed that Saif, 28, had a visa, which was valid for five years.

“Saif, while chatting on the Skype with his family on May 7 (Friday), told me that a person named Bill had called him from the US embassy in Santiago and asked him to come to the US embassy for some identification check-up,” The Dawn quoted Khan, as saying.

“My son became a victim of racial profiling and has been detained without a valid reason or evidence. His arrest was clearly a setup,” he added. (ANI)

Washing hands ‘can help dispel doubts’

Washington, May 7 (ANI): The next time you wash your hands, you might be removing doubts about recent choices.

That’s the conclusion of a new study.

To experiment this new theory, scientists Spike W. S. Lee and Norbert Schwarz, affiliated with the U-M Institute for Social Research (ISR) and the Ross School of Business in addition to the Department of Psychology conducted a study amongst undergraduate students.

The students were offered to pick 10 out of 30 CDs and rank them in order of their preference. Later, the experimenter offered them a choice between their 5th and 6th ranked CDs as a token of appreciation.

Following that choice, participants completed a seemingly unrelated product survey of liquid soap. Half of them merely examined the bottle before answering while the others tested the soap by washing their hands. After completing a filler task, participants were asked to rank the 10 CDs again.

“People who merely examined the soap bottle dealt with their doubts about their decision by changing how they saw the CDs: As in hundreds of earlier studies, once they had made a choice, they saw the chosen CD as much more attractive than before and the rejected CD as much less attractive. But hand washing eliminated this classic effect. Once participants had washed their hands, they no longer needed to justify their choice when they ranked the CDs the second time around,” Schwarz said.

The researchers replicated the findings by conducting a similar study using jars of fruit jams and antiseptic swipes, which replaced the CDs and the soap, respectively.

According to the authors, the results show that washing our hands can cleanse us from traces of past decisions, and rid us of the need to justify them.

The scientists are now contemplating if the effects of this study spread to other aspects of life as well, such as choice of one car over another or one partner over another.

The study is published in the current (May 7) issue of Science. (ANI)

Asbestos report questioned

A Clarence Valley resident says the local council’s response to the discovery of asbestos in gravel from one of its own quarries has been inadequate.

Traces of asbestos were discovered in the material late last year, and roads on which it had been used have since been sealed.

But Ewingar man Michael Mizzi says he is dissatisfied with a report the Clarence Valley Council has prepared on the issue.

Mr Mizzi says he is worried about what might have happened before the discovery was made.

“Nobody knows how many people have been exposed to this and it only takes a very small amount of asbestos to enter your lungs to create the possibility of disease further on in the future,” Mr Mizzi said.

“What has happened in the time that this material has been left to lie on the roads? That is between September and December last year.

“We don’t know how many people have been exposed to it, it was a very dry time of the year, it was a time when dust storms went through the area as well, so we’re not really sure what council is doing as far as that’s concerned.

“The council should at least contact residents and ask them to voice their concerns and get some input from the residents as to what they would like council to do.”

The council’s deputy general manager, Ron Donges, says he is still waiting for advice from the Health Department.

“We haven’t heard back from them yet and so we really can’t take that next step,” Mr Donges said.

“They’ve got the report and we’re waiting for their response, I think when it comes to the delegation of authority the health issues are best handled by the Department of Health and we’ll take their advice on that.”

Vitamin D vital for activating our immune defenses

London, March 8 (ANI): Vitamin D plays an important role in activating our immune defenses against infectious diseases like flu, says a new study.

According to the research, without sufficient intake of the vitamin, the killer cells of the immune system – T cells – will not be able to react to and fight off serious infections in the body.

For T cells to detect and kill foreign pathogens such as clumps of bacteria or viruses, the cells must first be ”triggered” into action and ”transform” from inactive and harmless immune cells into killer cells that are primed to seek out and destroy all traces of a foreign pathogen.

Scientists at the University of Copenhagen discovered that the T cells rely on vitamin D in order to activate and they would remain dormant, ”naive” to the possibility of threat if vitamin D is lacking in the blood.

For the research team, identifying the role of vitamin D in the activation of T cells has been a major breakthrough.

“Scientists have known for a long time that vitamin D is important for calcium absorption and the vitamin has also been implicated in diseases such as cancer and multiple sclerosis, but what we didn”t realize is how crucial vitamin D is for actually activating the immune system – which we know now,” the authors said.

The study has been published in the latest edition of Nature Immunology. (ANI)

Britain’s biggest UFO mystery revealed by Air Force base chief

London, Jul 9 (ANI): For years, Britain’s biggest UFO mystery had been kept under wraps, but now an Air Force official has admitted that an “extra-terrestrial” craft did visit the air base at Rendlesham Forest in 1980.

Former Deputy Base Commander Col Charles Halt claimed that even though the incident was later covered up, “extra-terrestrials” had been the cause of the close encounter in Suffolk.

Halt had led a group of airmen who reported seeing a triangular UFO taking off into the air, leaving traces of radiation behind.

“The UFOs I saw were structured machines moving under intelligent control and operating beyond the realm of anything I have ever seen before or since,” the Daily Star quoted Col Halt, now retired, as telling investigator Gary Heseltine.

“I believe the objects that I saw at close quarters were extra-terrestrial in origin,” he said.

He added that the Air Force later issued “dis-information” to throw the public off the scent.

His comments were hailed as “sensational” by former Ministry of Defence UFO investigator Nick Pope.

“This may help us to finally solve Britain’s biggest UFO mystery,” Pope said.

“It blows the MoD’s line that these events had ‘no defence significance’ out of the water,” he added. (ANI)

UK police suspects arson angle in teenage girl’s death case

London, June 27 (ANI): The UK Police is investigating the possibility of an arson attack in the death of a 15-year-old Pakistani-origin girl, who was seriously injured in a fire at her South London house.

Maleha Masud died in a hospital on Thursday night, while her three siblings received critical injuries in the blaze, raising suspicion of an arson attack on their family, the Daily Times reports.

City banker Zain Masud, 22, and his mother Rubina, 53, escaped by jumping from a first-floor window of their Lessingham Avenue house.

Paramedics dragged three other children from the burning house.

The London police confirmed the blaze was being treated as suspicious, and said they had found traces of an accelerant.

Two teenager boys have been arrested in connection with the fire and bailed until August, pending further inquiries. No charges have yet been brought. (ANI)

Traces of microbes in shallow ice layers may help find life on icy worlds

Washington, June 26 (ANI): A new research has indicated that living microorganisms and the food that sustained them can be detected in shallow ice layers, which will help find life on icy worlds.

The research is a part of the Project SLIce, which means, Signatures of Life in Ice.

Dominique Tobler and Jennifer Eigenbrode of NASA Goddard Space Science Laboratory, and Liane Benning of the University of Leeds, UK, show that not only living micro-organisms, but also traces of long-dead ones, and the food that sustained them can be detected in shallow ice layers, using methods rigorously tested in one of our own planet’s most extreme environments.

“With SLIce, we wanted to figure out the nature of the organic matter in ice and how what we find on Earth can be the basis for comparisons with organic matter on Mars,” explained Benning.

“The organic matter we find could be alive or dead, representing extant or extinct life, or even the nutrients that made life possible, and we want to identify the biological signals that point towards ice-dwelling life,” she added.

The SLIce team went to a glacial region of Svalbard to try taking ice samples in exactly the way it would be done on Mars, using a sequence of procedures and tests that they had developed as part of the AMASE project, a long-running international research program that has established Svalbard as a test bed for planetary exploration.

“We’re using sample devices, primarily to be operated from a rover, but we’re also testing how we go about taking and testing samples and keeping them separate,” said Benning.

“For SLIce, we applied the protocol we had developed to take ice cores, process them and analyze them in the field just as would happen on a rover on Mars, and then of course we took them back to the lab and did a much wider range of tests, so we really knew what we had found,” she said.

“There could be microbes living in the ice, but there could also be the dead bodies of microbes that used to live there, and there could be biological molecules that blew in from dust and micrometeorites. We need to identify what we’ve got, so that we know what it’s telling us,” she added. (ANI)

Brazil’s petroleum giant finds oil in Campos Basin

RIO DE JANEIRO, May 22 (Xinhua) — Brazil’s state-owned oil and gas giant Petrobras said Friday that it has discovered traces of oil in an exploration block off the county’s southeastern coast.

The discovery was made in the block BM-C-25 in the Campos Basin off the coast of Espirito Santo state.

The block had been operated by the Dutch company Shell in a partnership with Petrobras since 2002.

In March 2009, Shell decided to sell its 45-percent share of the block to Petrobras.

It was the second time this week that Petrobras announced the discovery of oil traces in areas previously owned by foreign companies.

On Monday, the company informed Brazil’s National Petroleum Agency of the evidences of oil reserves in the offshore BM-S-3 block in the Santos Basin.

Archaeologists find rare bronze coin in Saudi Arabia

Riyadh (Saudi Arabia), May 11 (ANI): A rare bronze coin and remains of Nabatean potteries were discovered at the Domat Al-Jandal archeological site in Saudi Arabia by a team of archaeologists carrying out preliminary exploration work.

“It is very difficult to unearth what is below the soil but we are extremely happy to discover the antiquities after digging seven meters into the ground,” Italian archeologist Alessandro De Maigret, head of the team, told Arab News.

He said that extensive excavations would continue in the area to find the traces of the oldest inhabitants in Domat Al-Jandal. The Adomato Kingdom existed in the area during 685 BC.

“Domat Al-Jandal is an important historic site and it’s one of the oldest civilizations in the Arabian Peninsula,” he said.

It is also linked to Syrian and Yemeni civilizations of the past.

“Domat Al-Jandal is considered a link that connects these civilizations because of its location on the trade route,” said Alessandro.

“The oldest recorded history about this place dates back to the seventh and eighth centuries before Christ,” he added. (ANI)

Saddam alleged that he was tortured before his hanging

Washington, May 5 (ANI): In letters from jail, Saddam Hussein alleged that he was tortured, and also complained of sleepless nights

Hussein, who was captured in 2003, said that the “detention gang” was after him night after night.

Saddam poured out his complaints “to whom it may concern” in two Christmas 2003 letters, handwritten in Arabic, which he gave to his U.S. military jailers, the Daily News has learned.

In one letter, he alleged “beatings that I have received following my capture,” in which “not a single part of my body was spared of the severe harm that was inflicted by the detention gang,” adding, “some of the traces are still visible on my body.”

The tyrant and his family, who maintained their 24-year reign over Iraq by torturing and executing thousands, complained that his lockup – believed to be at Baghdad International Airport – was an American-made chamber of horrors.

“My opportunity to sleep in this place is limited and almost scarce. I don’t think there is anyone with a sensitive and humanitarian heart who can sleep amidst the screams of the tortured and the many blows of the doors and the squeaking sounds of the chairs,” he said.

Saddam whined that his “total hours of sleep did not exceed four to five hours.”

The letters were among 352 pages in his declassified FBI file, which The News requested after his December 2006 execution for crimes against humanity. (ANI)

Police: Youth admits taking part in killing of family of four

Eislingen, Germany – A 19-year-old youth has admitted to taking part in the killings of four members of a family in south-west Germany, prosecutors said on Friday.

The teen told police that he and his friend, 18, gunned down the friend’s parents and two sisters at the family’s apartment in Eislingen a week ago, a spokesman for the prosecutor’s office in nearby Ulm said.

The youth did not give a motive for the killings, which were carried out with two pistols stolen last year from a local marksmen’s club frequented by the 18-year-old.

The guns and 31 rounds of used ammunition were found in a woods wrapped in a plastic rubbish bag. The 19-year-old said his friend had hidden them there, according to police.

Police said the duo behaved like professional killers. They first shot dead the two sisters, aged 24 and 22, while their parents were out for the evening with friends in a local restaurant.

They then went to the restaurant themselves and joined the parents, returning to the apartment an hour later to wait for the couple, aged 57 and 55, to come back.

An hour later, in the early hours of April 10, they shot dead the two adults in the hallway of the flat, police said.

The 18-year-old has remained silent about what happened since he and his friend were detained for questioning a day after the killings.

Investigations showed traces of powder burns on the hands of both youths, indicating they had recently fired guns.

The killings were reported to police by 18-year-old, who said he found the bodies of his family when he returned home after spending the night with his friend.

Police immediately suspected a family member or someone with close links to the family because there were no traces of a break-in and the flat was not ransacked.

The father practiced alternative medicine in the basement of the apartment building, which was owned by the family. The mother was a teacher and her daughters were studying to be teachers.

The killing occured three days after a man opened fire in a court in Bavaria, killing his sister-in-law and injuring two other people before turning his gun on himself.

That shooting happened less than a month after a teenager went on the rampage in and around his former school in Winnenden, south-west Germany, killing 15 people. (dpa)

Cyclist Armstrong could face sanctions for violating doping rules

London, Apr 10 (ANI): Cycling legend Lance Armstrong could face sanctions from the French anti-doping agency after being accused of violating rules during a random test in March.

The seven-time Tour de France winner is accused of “not respecting the obligation to remain under the direct and permanent observation” of the tester, the Daily Express reported.

The row stems from an unscheduled visit of an agency tester to his residence during a training stint in France.

The American took a 20-minute shower while having the tester’s identity checked before letting him carry out his duties.

Tests on Armstrong’s hair, urine and blood found no traces of drugs.

Armstrong said: “I had no idea if this guy was telling the truth – his papers weren’t clear.”

“I find it amazing that I’ve been tested 24 times without incident and the first test I do in France results in outrageous allegations,” he added. (ANI)

Darwin ‘spent more on food than books during college days’

London, Mar 22 (ANI): Charles Darwin’s life during college days was quite different from what many would expect. He used to spend very little time studying or in lectures, preferring to shoot, ride and collect beetles, suggest newly discovered bills.

Historians have gained new insight into Darwin’s life as a college student after unearthing bills that record personal details of how he spent his money.

According to the bills, the revolutionary scientist happily paid others to carry out menial tasks for him, such as stoking his fire and polishing his shoes.

However, when it came to books, there is very little evidence to support the fact that he invested in textbooks, or that he did much else to further his studies.

The records were found in six previously overlooked college books, and are due to be published online on the Complete Works of Charles Darwin website (darwin-online.org.uk).

Darwin’s time at Cambridge, from 1828 to 1831 is also one for which there is a comparative shortage of information.

In total, Darwin’s college bills amounted to around 637 pounds over the three years, which did not include the 14 pounds he paid for his BA degree in 1831 or the 12 pounds he spent collecting his MA in 1836, following his return from the Beagle voyage.

The bills also show that in addition to the basic college dinner ration of a joint of meat and a glass of beer, he was prepared to spend money on fresh vegetables each day.

“Before this, we didn’t really know very much about Darwin’s daily life at Cambridge at all,” The Guardian quoted Dr John van Wyhe, director of the Darwin website, as saying.

“It had been assumed that there were no significant traces of his time here left to discover, which meant that we were short of information about one of the most formative parts of his life.

“Now, in his 200th anniversary year, we have found a real treasure trove right in the middle of Cambridge,” he said.

“How much he spent on alcohol, for example, or to have his horse stabled, we still don’t know,” added Van Wyhe, a science historian at the University of Cambridge and founder of the website. (ANI)

95 million year old fossils reveal earlier origin for modern octopus

Washington, March 18 (ANI): Scientists have found five specimens of 95 million year old fossils of Cretaceous octopuses, which reveals a much earlier origin for the modern octopus.

The five specimens have been found by palaeontologists in Cretaceous rocks in Lebanon, which have astonishingly preserved the octopuses’ eight arms with traces of muscles and those characteristic rows of suckers.

The chances of an octopus corpse surviving long enough to be fossilized are so small that prior to this discovery only a single fossil species was known, and from fewer specimens than octopuses have legs.

Even traces of the ink and internal gills are present in some specimens.

“These are sensational fossils, extraordinarily well preserved”, said Dirk Fuchs of the Freie University Berlin, lead author of the report.

But, what surprised the scientists most was how similar the specimens are to modern octopus.

“These things are 95 million years old, yet one of the fossils is almost indistinguishable from living species,” they said.

This provides important evolutionary information.

According to scientists, “The more primitive relatives of octopuses had fleshy fins along their bodies. The new fossils are so well preserved that they show, like living octopus, that they didn’t have these structures.”

This pushes back the origins of modern octopus by tens of millions of years, and while this is scientifically significant, perhaps the most remarkable thing about these fossils is that they exist at all. (ANI)

Johnson’s Baby Shampoo ‘contains cancer-causing chemicals’

London, Mar 15 (ANI): Popular bath products for kids contain cancer-causing chemicals, says a new study.

According to a research carried out in the United States, many of the top-selling brands contain formaldehyde, which is used to embalm corpses.

Out of the 28 products tested for formaldehyde in an independent laboratory, 23 contained it, reports Sky News.

Others had traces of 1,4-dioxane, a foaming agent which is also believed to be a cancer risk for humans. Of the 48 items tested for 1,4-dioxane, 67 percent contained it.

Apparently, both substances were found in Johnson’s Baby Shampoo, L’Oreal Kids Extra Gentle 2-in-1 shampoo and Pampers Kandoo foaming soap.

Stacy Malkan from the Campaign for Safe Cosmetics, who commissioned the tests, said: “If chemicals are causing cancer in animals, we really shouldn’t be putting them on babies’ heads.”

The Personal Care Products Council, however, accused the group of preying on parents’ fears and described the results as “patently false”. (ANI)

Horses were domesticated 1,000 years earlier than thought

Washington, March 6 (ANI): An international team of archaeologists has uncovered the earliest known evidence of horses being domesticated by humans, dating back to 5,500 years ago, which is 1,000 years earlier than thought. ed by the Universities of Exeter and Bristol (UK), the discovery could point to the very beginnings of horse domestication and the origins of the horse breeds we know today.

The researchers have traced the origins of horse domestication back to the Botai Culture of Kazakhstan circa 5,500 years ago.

This is about 1,000 years earlier than thought and about 2,000 years earlier than domestic horses are known to have been in Europe.

Their findings strongly suggest that horses were originally domesticated, not just for riding, but also to provide food, including milk.

Through extensive archaeological fieldwork and subsequent analysis, using new techniques, the team developed three independent lines of evidence for early horse domestication.

Their findings show that in the fourth millennium BC horses in Kazakhstan were being selectively bred for domestic use.

They also show horses were being harnessed, possibly for riding, and that people were consuming horse milk.

Analysis of ancient bone remains showed that the horses were similar in shape to Bronze Age domestic horses and different from wild horses from the same region.his suggests that people were selecting wild horses for their physical attributes, which were then exaggerated through breeding.

The team used a new technique to search for ‘bit damage’ caused by horses being harnessed or bridled. The results showed that horses had indeed been harnessed, suggesting they could have been ridden.

Using a novel method of lipid residue analysis, the researchers also analysed Botai pottery and found traces of fats from horse milk.

Mare’s milk is still drunk in Kazakhstan, a country in which horse traditions run deep, and is usually fermented into a slightly alcoholic drink called ‘koumiss’.

While it was known that koumiss had been produced for centuries, this study shows the practice dates back to the very earliest horse herders.

According to Lead author Dr Alan Outram of the University of Exeter, “The domestication of horses is known to have had immense social and economic significance, advancing communications, transport, food production and warfare.”

“Our findings indicate that horses were being domesticated about 1,000 years earlier than previously thought. This is significant because it changes our understanding of how these early societies developed,” he added. (ANI)
