A study carried out in the United Kingdom revealed that the life expectancy for men could be reduced by 10–15 years after the age of 50 due to smoking.

The British Medical Journal carried out a study over a time period of 38 years in the United Kingdom which examined the health of 19,000 men aged 40–69. They were examined between 1967–1970. After tracing the history of the men, the survey revealed that smoking, high blood pressure and high cholesterol reduced the life expectancy of men by 10–15 years after they reached the age of 50. The research was published on the BMJ‘s website on Friday.

The researchers from the University of Oxford in England were focussing on smoking, high blood pressure and cholesterol due to the fact that they are the main cardiovascular risk factors. Dr. Robert Clarke from the university said: “We’ve shown that men at age 50 who smoke, have high blood pressure and high cholesterol levels can expect to survive to 74 years of age, while those who have none of these risk factors can expect to live until 83. It is precisely this kind of very prolonged follow-up study that is necessary to get these results — that modest differences in heart risk factors can accurately predict significant differences in life expectancy.”

“The results give people another way of looking at heart disease risk factors that can be understood more readily. If you stop smoking or take measures to deal with high blood pressure or body weight, it will translate into increased life expectancy.”

Gabriel Amorth, the Roman Catholic Church’s leading exorcist, has suggested missing schoolgirl Emanuela Orlandi was kidnapped for sexual abuse at orgies attended by foreign diplomats and arranged by Vatican police. Orlandi was fifteen when she vanished in 1983.

Amorth, 85, who was appointed by the late Pope John Paul II, makes his remarks as Italian police try to determine if bones buried near the body of a mobster belong to Orlandi. Anonymous claims have suggested the tomb of Enrico “Renatino” De Pedis contains clues to her disappearance.

Investigators are examining bones removed from his burial site in the Basilica of Sant’Apollinare. Buried in a nearby crypt, the bones are thought to be centuries old but forensic tests are ongoing. One theory is Pedis kidnapped Orlandi to press Vatican officials over a financial dispute, with his onetime lover claiming her body was disposed of in a cement mixer.

Amorth refutes this explanation, and also an alleged “international dimension”; another theory is that the kidnapping was to try and secure freedom for Mehmet Ali Agca of Turkey, who shot at the pope in 1981. Orlandi’s vanishing “was a crime with a sexual motive” says Amorth. “Parties were organised, with a Vatican gendarme [policeman] acting as the ‘recruiter’ of the girls.”

He further told La Stampa “The network involved diplomatic personnel from a foreign embassy to the Holy See. I believe Emanuela ended up a victim of this circle”. “It has already previously been stated by [the late] monsignor Simeone Duca, an archivist at the Vatican, who was asked to recruit girls for parties with the help of the Vatican gendarmes.”

Orlandi has not been seen since she set off from the family apartment in the Vatican City, heading for a Rome music lesson. Orlandi’s father worked for the Holy See. Amorth is a controversial priest who lays claim to thousands of exorcisms and has criticised activities such as yoga and children reading Harry Potter books as spiritually harmful.

VIENNA —Doctors from the Rudolfinerhaus clinic in Vienna say “there is no doubt” Ukrainian opposition leader Victor Yushchenko was poisoned with Dioxin.

Yushchenko’s body had about 1,000 times more than the normal concentration of the toxin. It is unknown if there were any other poisons in his system.

Although it has not yet been proven that the poisoning was deliberate, doctors suspect it was. “We suspect a cause triggered by a third party,” said Michael Zimpfer, head doctor at the Rudolfinerhaus clinic. He suggested the poison may have been administered orally, through food or drink.

Today’s announcements are a follow-up of an earlier press conference, where Dr. Korpan that there were three hypotheses under consideration, one of them involving dioxin. He did not reveal what the other two hypotheses were. Dr. Michael Zimpfer, director of the Rudolfinerhaus clinic emphasized that time there was no proof yet to specify the substance causing the illness.

Yushchenko left Kiev on Friday (2004-10-12) for further examination in Vienna. When Yushchenko fell ill on October 6th, Ukrainian doctors had initially diagnosed food poisoning, leading to speculation that he had been poisoned deliberately. The illness has disfigured Yushchenko’s body and face which doctors say could take up to two years to heal.

He fell seriously ill on the September 6th, during his presidential campaign. Yushchenko was taken to the Rudolfinerhaus clinic of Vienna, where he stayed for four days under Dr. Korpan’s care. He was diagnosed with “acute pancreatitis, accompanied by interstitial edematous changes.” These symptoms were said to be due to “a serious viral infection and chemical substances which are not normally found in food products” as his campaign officials put it. In laymans terms, he developed an infection in the pancreas and got a bad skin condition that disfigured his face with cysts and lesions. The skin condition has similarities with the chloracne associated with dioxin posioning according to a British toxicologist John Henry.

After lots of speculations and speculative London betting on the outcome it has been announced that British author Doris Lessing (“The Golden Notebook”, 1962) is the winner of the 2007 Nobel Prize for Literature.

At the International Book Fair at Frankfurt, Germany, which is currently underway, this decision has met with general approval, as a decision awarding the literary work of an author well established beyond her native country, rather than a political statement. The reason given for giving the prestigious award to Doris Lessing was to honour “that epicist of the female experience, who with skepticism, fire and visionary power has subjected a divided civilisation to scrutiny”.

Lessing herself, who will turn 88 on October 22, has been named a potential candidate over the last 30 years – so long in fact, that she herself once exclaimed: “I’ll never get it”. Finally, on December 10, 2007, the Nobel Prize including 10 million Swedish Kronor (€1.1 million) will be awarded to her in Stockholm, Sweden.

On Monday, digital security researchers Mathy Vanhoef and Frank Piessens of Belgium’s KU Leuven university publicly disclosed a security vulnerability in the WPA2 Wi-Fi (wireless local-area networking) protocol, which they called KRACK (for Key Reinstallation Attack). Their study claimed KRACK affects every modern device using Wi-Fi; it can be fixed by a software update, researchers said.

Vanhoef wrote, “Attackers can use this novel attack technique to read information that was previously assumed to be safely encrypted. This can be abused to steal sensitive information such as credit card numbers, passwords, chat messages, emails, photos and so on.” Vanhoef notified vendors about the flaw in July, including UNIX-like operating system OpenBSD. “If your device supports Wi-Fi, it is most likely affected. […] In general, any data or information that the victim transmits can be decrypted”, he wrote.

The study papers, which were submitted for review on May 19, were kept in confidence allowing companies to fix the security flaw. The United States-based Computer Emergency Response Team (CERT) informed vendors on August 28. The Wi-Fi Alliance said it “could be resolved through a straightforward software update.” OpenBSD released their software patch on August 30.

Exploring the flaw which affected every device the researchers had tested, National Cyber Security Centre of the UK said “the attacker would have to be physically close to the target”. But due to this flaw, an attacker can send malware or ransomware on the websites, Vanhoef claimed.

Linux-based operating systems including Android v6.0 and higher are especially affected by this flaw, while Windows and iOS are not as vulnerable as Android by this flaw as they do not fully implement WPA2.

Microsoft reportedly has released security patches for Windows 7, 8, 8.1 and 10. Google said Android operating systems would receive the updates in the software update scheduled to be made available on November 6. Apple has implemented the patch in the beta versions of their operating system iOS, macOS, tvOS and watchOS, however it is yet to roll out patches for stable operating systems.

WPA2 protocol has been used for more than a decade, and has been compulsory for Wi-Fi since 2006. KRACK would also affect various home appliances which can be controlled over Wi-Fi, within the so-called “Internet of things”. Andrew Martin from Oxford University said, “We can be sure a lot of these devices won’t be patched[…] Whether that matters for this attack or only for some future attack is yet to be seen.”

The study and its findings are scheduled for presentation at the ACM (Association for Computing Machinery) Computer and Communications Security conference on November 1.

NASA is beginning the final preparations for next Wednesday’s launch of the Dawn probe, aboard a Delta II rocket. The Dawn probe, costing over US$250 million, will visit the dwarf planet Ceres and the asteroid Vesta. The launch was originally planned for mid-June, however due to a damaged crate, shipping delays, and a damaged solar panel, NASA chose to delay it until now. Last week the spacecraft was delivered to the launch pad, and engineers performed tests to ensure that it is ready for launch. Today, the payload fairings were installed, and the probe is ready for its launch next week onto its 5 billion kilometer (3.2 billion mile) mission.

As the Delta II launches, three stages of rockets will propel the probe towards its first target. With the help of ion thrusters, it will reach Mars in mid-2009. Using Mars’ gravity, the probe will speed up and proceed towards the first asteroid, Vesta, in late 2011. After orbiting for seven months, it will leave Vesta in mid-2012, and arrive at Ceres in 2015. After making scans of Ceres, it will enter an orbit around Ceres that will ensure that it does not impact the asteroid for half a century. This is required due to the United Nations’ “Outer Space Treaty”, which states that “harmful contamination” of these asteroids must be avoided.

The targets of this mission, Ceres and Vesta, couldn’t be less alike. Ceres (diameter 975 km, 600 miles) is larger than Vesta (578 km, 350 miles). This makes Ceres approximately the size of Texas. NASA believes Ceres could contain water beneath its outer crust because, like Earth, its inner layers are heavier than the outer layers, and Ceres’ outer layer is lighter than water. Vesta, on the other hand, is the size of Arizona, and has a surface of volcanic rock, which astronomers believe came from its hot inner layers. Vesta also has a large crater – almost 500 km (300 miles) across – on its southern pole. The collision that caused this likely blasted enough rock into space to fill a container 160 by 160 by 80 km (100 by 100 by 50 miles).

The probe will make several observations of these asteroids: it will compare the makeup, shape, size, and densities, analyze craters, and determine mass, gravity, rotation. To determine the makeup, the probe carries a mapping spectrometer, and tools to map emissions of neutrons and gamma rays. Using this information, NASA can compare the formation of these bodies to learn more about our solar system, for example, to test a theory which states that a number of stony meteorites may be debris from Vesta.

There’s one more piece of equipment aboard the probe: A small silicon chip containing the names of 350,000 people who submitted their names to the “Send Your Name to the Asteroid Belt” campaign. After next week’s launch, the spacecraft will deploy its solar panels and undergo two months of testing before it begins the cruise to Mars.

Saturday, March 5, 2005Simply massaging low birth weight babies with sunflower seed oil can protect them from potentially fatal infections.

Infections and complications from preterm birth cause more than half of all neonatal deaths, and very low birth weight babies are particularly vulnerable.

Preterm babies have immature skin that lacks a protective film called vernix that has antimicrobial properties.

In some countries, such as India, newborns are routinely massaged with mustard oil.

But mustard oil, says Gary Darmstadt of John Hopkins University in Baltimore, Maryland, can delay recovery of the skin barrier and have a toxic effect on skin.

Seeking an alternative low-cost product, Darmstadt and colleagues experimented with sunflower oil and an ointment called Aquaphor that comprises petrolatum, mineral oil, mineral wax and lanolin.

The researchers tested the treatments on 497 newborns (72 hours old or less) and preterm babies (less than 33 weeks gestation) between 1998 and 2003 in Bangladesh.

They applied the treatments to the entire body besides the scalp and face three times daily for the first 14 days and then twice daily until discharge.

Babies treated with sunflower oil were found 41% less likely to develop infections than controls.

“Evidence is emerging that the skin is much more important as a barrier to infection than previously recognized, particularly in preterm infants whose skin is underdeveloped,” says Darmstadt. “The good news is that treatment is available to strengthen the function of the skin as a barrier in these vulnerable newborns.”
