The Kennedy Center announced that its 30th presentation of the Kennedy Center Honors would go to pianist Leon Fleisher, comedian Steve Martin, singer Diana Ross, director Martin Scorsese and musician Brian Wilson. The Center was opened to the public in 1971 and was envisioned as part of the National Cultural Center Act, which mandated that the independent, privately-funded institution would present a wide variety of both classical and contemporary performances, commission the creation of new artistic works, and undertake a variety of educational missions to increase awareness of the arts.

In a statement, Kennedy Center Chairman Stephen A. Schwarzman said that “with their extraordinary talent, creativity and perseverance, the five 2007 honorees have transformed the way we, as Americans, see, hear and feel the performing arts.”

Fleisher, 79, a member of the Peabody Institute‘s music faculty, is a pianist who lost use of his right hand in 1965 due to a neurological condition. He became an accomplished musician and conductor through the use of his left hand. At 67, he regained the use of his right hand. With the advent of Botox therapy, he was once more able to undertake two-hand performances in 2004, his first in four decades. “I’m very gratified by the fact that it’s an apolitical honor,” Fleisher said. “It is given by colleagues and professional people who are aware of what [an artist] has done, so it really is apolitical — and that much more of an honor.”

Martin, 62, a comedian who has written books and essays in addition to his acting and stand-up comedy career, rose to fame during his work on the American television program Saturday Night Live in the 1970’s. Schwarzman praised his work as that of a “renaissance comic whose talents wipe out the boundaries between artistic disciplines.” Martin responded to the honor saying, “I am grateful to the Kennedy Center for finally alleviating in me years of covetousness and trophy envy.”

Ross, 63, was a product of Detroit‘s Brewster-Douglass Projects when as a teeager she and friends Mary Wilson and Florence Ballardis formed The Supremes, a ground-breaking Motown act. She portrayed singer Billie Holiday in the 1972 film Lady Sings the Blues, which earned her an Oscar nomination and a Golden Globe award. “Diana Ross’ singular, instantly recognizable voice has spread romance and joy throughout the world,” said Schwarzman. Ross said she was “taken aback. It is a huge, huge honor and I am excited to be in this class of people.”

Scorsese, 64, is one of the most accomplished directors the United States ever produced, whose work includes Mean Streets, Taxi Driver, GoodFellas, Cape Fear, The Last Temptation of Christ and The Departed, for which he won a 2006 Academy Award for Best Director after being nominated eight times. Scorsese said, “I’m very honored to be receiving this recognition from the Kennedy Center and proud to be joining the company of the very distinguished individuals who have received this honor in years past.”

Wilson, 65, along with his brothers Dennis and Carl, formed the Beach Boys in 1961. They had a series of hits that included “Surfin’ U.S.A.” and “Wouldn’t It Be Nice.” Their 1966 album Pet Sounds is considered one of the most influential recordings in American music. “This is something so unexpected and I feel extremely fortunate to be in the company of such great artists,” said Wilson, who is currently on tour.

The Kennedy Center’s board of trustees is responsible for selecting honorees for “lifetime contributions to American culture through the performing arts.” Previous honorees, including Elton John and Steven Spielberg, also submitted recommendations. A wide variety of people were under consideration, including Emanuel Ax, Evgeny Kissin, Renee Fleming, Laurence Fishburne, Francis Ford Coppola, Melissa Etheridge and Kenny Chesney.

President Bush and first lady Laura Bush will attend the center’s presentation at its opera house on December 2, 2007, which will broadcast on December 26 on CBS.

In findings published earlier this month in Ecological Applications, scientists from the University of Washington and Center for Ecosystem Sentinels examine the reason for the plummeting numbers of female Magellanic penguins, Spheniscus magellanicus, that have been reported at the birds’ breeding sites in South America over the past twenty years and more. Wikinews caught up with postdoctoral researcher and study co-author Natasha Gownaris to learn more.

In a press release, Gownaris said, “Two decades ago, there were about 1.5 adult male Magellanic penguins for every adult female at Punta Tombo[…] Today, it’s approaching three males for every female.” The findings suggested a disparity in the death rate of juvenile and adult penguins, rather than differences in chick survival, account for this difference.

Punta Tombo is one of the annual breeding sites for the species; it is in Argentina. The penguins travel thousands of miles each year to reach these sites.

The work involved building population models out of over thirty years of data collected by tagging individual penguins. Findings also suggested the pronounced sex disparity might make population models used to predict survival among other birds with a more even gender balance inappropriate for use on Megallanic penguins.

According to the data, since 1987, overall population of Magellanic penguins in Punta Tombo at one of their annual breeding sites in Argentina has declined 40%, while the male-to-female ratio has greatly increased.

Since 1983, the research team has been putting stainless steel bands on tens of thousands of chicks hatched at the Punta Tombo breeding site in Argentina, noting which juvenile and adult birds make it back to the site the next year and extrapolating how many lived and died. Among juveniles, there was a 17% survival rate for males and 12% for females. Among adults, it was 89% and 85%. These effects became compounded every year, reaching as high as six males to one female among older penguins.

The researchers noted implications for penguin conservation: Gownaris remarked, “Over the years, this team has helped preserve the land and waters around breeding colonies like Punta Tombo[…] But now we’re starting to understand that, to help Magellanic penguins, you have to protect waters where they feed in winter, which are thousands of miles north from Punta Tombo.”

Gownaris answered a series of questions for our correspondent.

((Wikinews)) What prompted your curiosity about Magellanic penguins?

Natasha Gownaris: I’ve wanted to be a marine scientist since I was a child, when I would collect sand crabs (Emerita talpoida) from local beaches in New York. I studied fish as a graduate student, but I have a pair of adopted parrots and I am generally fascinated by birds. Plus, penguins eat fish! Studying penguins seemed like a great way to merge my love for the ocean and my love for birds. Penguins and other seabirds are also important to study because they tell us something about the health of the ocean ecosystems they feed in, similar to the use of canaries to test air quality in coal mines. Unfortunately, the decline of many seabird species worldwide is yet another warning sign of the negative and widespread impacts humans are having on the ocean.

((WN)) How did you approach putting together such a large-scale study?

NG: This study started in 1982, long before my joining the lab in March of 2016. Dr. Dee Boersma began this study as a response to a Japanese company’s interest in harvesting penguins for their skin, meat, and oil. Although the project has evolved over time, Dr. Boersma had the foresight to start banding chicks in 1983 and to set up a standard protocol that we follow each year. Since then, over 44,000 chicks have been banded at Punta Tombo. We’ve been able to follow some individuals for 30+ years, collecting detailed information on things like how often they breed and how many mates they’ve had.

((WN)) How much time did you end up spending in Argentina? What was it like at the breeding site?

NG: Members of the Boersma lab and volunteers spend approximately six months each year at Punta Tombo. I was fortunate enough to spend nearly four months at the colony between 2015 and 2017. It’s an incredible, otherworldly place. Magellanic penguins nest in burrows or bushes, and some areas of the colony are so dense with burrows that you feel like you’re on a different planet. The colony has declined by over 40% since the study started…so I can’t even imagine what it was like in the 1980s. My favorite time of the day is around 8PM, when (hopefully fat) penguins are returning to the colony en masse after a foraging trip. They are also most vocal in the morning and evening, making their characteristic braying sound— the related African penguin earned the name “jackass penguin” because they sound a bit like donkeys. The colony is also full of other beautiful and interesting creatures, including a llama-like species called the guanaco and an ostrich-like species called the rhea.

((WN)) Do you have any theories on why more female juveniles die at sea? You mention starvation; what might be the causes of that, and are there other possible explanations you can think of?

NG: We are not yet certain why females are more likely to die, but we think it must be related to their smaller body size. Because the mortality is most uneven in juveniles, higher mortality doesn’t seem to be related to greater costs of breeding for females than for males. Female Magellanic penguins are about 17% lighter than males and have smaller bills. We think that, because of this size difference, females have a lower storage capacity, can’t dive as deep, and can’t take as wide a range of prey as males — all disadvantages when faced with limited and unpredictable food resources. These disadvantages hit juvenile females even harder, as juveniles are still learning how to forage and often travel further than adults do in the non-breeding season. Counts of carcasses in the species’ migration range support starvation as the main cause of female-biased mortality; while oiled carcasses have a sex ratio of 1:1, females outnumber males in carcasses of starved birds. The only other possibility is that females are moving to other colonies at higher rates than are males, but this species is known to almost always return to its natal colony to breed.

((WN)) You suggest conservation efforts should look at protection of feeding grounds. What sort of measures do you think might be beneficial?

NG: Because penguins migrate such long distances over the non-breeding season, a mixture of tools (including no-take marine protected areas and traditional fisheries management tools, like catch limits) is likely to be needed. Although there is currently some spatial protection surrounding the species’ breeding colony, this protection does not extend to their migratory route. And, of course, everyone can contribute to penguin conservation by reducing their plastic waste, making more sustainable food choices, and reducing their carbon footprint.

((WN)) What do you think might be causing pressure on food sources for the penguins?

NG: The two main threats to the food sources of this colony are climate change, which cause shifts in primary productivity and fish stocks, and fisheries. Fisheries compete with penguins for fish species such as hake and anchovy.

((WN)) Have you noticed differences in behavior among the penguins as the ratios become increasingly skewed?

NG: In a separate study currently under review, we have shown that aggression between males of Magellanic penguins is higher when the sex ratio at the colony is more skewed towards males. We also showed that nearly all females at the colony breed but that, over time, fewer and fewer males find mates. Single male penguins sometimes intrude [on] nests of mated pairs and interrupt the incubation of eggs or feeding of chicks, leading to mortality. In some cases, they will even attack and kill chicks.

((WN)) Your release mentioned sexing the penguins was problematic; how did you achieve it with confidence?

NG: We have some methods of sexing penguins that we feel confident about — using genetics or measures of cloaca size around egg laying, for example. However, these methods are time intensive, so we have also developed visual cues for sex penguins (bill size, behavior, forehead shape). We looked at individuals that had been sexed using both a certain method (e.g. genetics) and visual methods to calculate how often we got it right based on visual cues alone and found that we have very high accuracy. We also used statistical tools to help to deal with uncertainty in the sex of some individuals.

((WN)) How well can you extrapolate population trends at Punta Tombo based on the birds you tagged? More broadly, how well do you think this work represents global populations?

NG: It is likely that females have higher mortality than males at other colonies of this species and in other penguin species. We unfortunately do not have enough information from other colonies of this species (e.g. sex ratio and population trends) for an accurate global assessment of population trends. We do know that some colonies of the species are growing but that, at the global level, the species is still in decline.

((WN)) In your opinion, for how much longer are penguin populations sustainable without intervention?

NG: This is nearly impossible to answer without more information on other colonies of the species, but the Punta Tombo colony is declining rapidly. We estimate declines of at least 43% since 1987 from our annual surveys at the colony, but it is likely that actual declines are higher because of the increasingly skewed sex ratio.

((WN)) What are your next plans moving forward with your work?

NG: We are currently studying the sex ratio in Magellanic penguin chicks (at hatching and at fledging) to determine how this influences the sex ratio in adults. There are two priorities moving forward — 1) estimating sex ratio at other colonies of this species and determining whether females are more likely to leave Punta Tombo for other colonies than are males and 2) determining the mechanisms underlying lower female survival, e.g. by studying the foraging behavior and diet of males and females and the individual characteristics (like body size) that correlate with survival.

On November 17 and November 18, Wikinews attended the 2018 Bangalore Comicbook Convention, in Karnataka, India. Beginning on Saturday morning, the ComicCon continued till Sunday. Organised by ComicCon India, who organised Comic Con in Hyderabad in October, this event was held at Karnataka Trade Promotion Organisation (KTPO)’s convention hall. Wikinews spoke to convention’s international guests Ryan O’Sullivan, Dan Watters, and Vanesa Del Ray.

UK-based freelancer comicbook writer Ryan O’Sullivan, who has worked for Image Comics and Vault Comics, and wrote video game comics including Eisenhorn, Warhammer 40,000, and Dark Souls, was one of the guests attending ComicCon. Along with him, London-based freelance comic book writer Dan Watters was also one of the attendants. Watters has worked with Image Comics on Limbo, as well as Lucifer for Vertigo Comics. Watters has also written comics for Assassin’s Creed, Wolfenstein and Deep Roots. Cuban comic book artist Vanesa Del Rey was also one of the guest attendants, who has illustrated Scarlet Witch, Daredevil Annual, and Spider-Women Alpha for Marvel Comics; and Redlands for Image Comics.

The convention started at 11 AM. Crossing between the genres of science fiction, horror, anime, fantasy and comics, the event sprawled throughout all corners of the facility. Marvel Zone, Amazon Video zone, AXN Live RED Special Session, Warner Bros’ Aquaman and Fantastic Beasts: Crimes of Grindelwald experience, and Sony Pix zone attracted large number of audience.

On day two, Sumit Kumar, creator of Chin Chin, inspired by Chacha Chaudhary and Tintin, had a panel in the afternoon.

At 1:30 PM, there was a video presentation by Yali Dream Creations. The video was about The Village. Yali Dream Creations’ Shamik Das Gupta said the story of their comic The Village is “supernatural, social, horror”. Later, there was another presentation about their other comic, Rakshak ^{((hi))Hindi language: ?Protector} — A Hero Among Us, about a masked vigilante in India. The first part of the four-part comic was released in 2016’s Delhi ComicCon, Gupta said. Gupta also added “Delhi gang rape story pushed me”. The session ended around 1:45 PM.

After Yali Dream Creations, there was a comic launch by Rahil Mohin. Mohin had previously launched Sufi Comics in 2008, The Wise Fool of Baghdad and two comics about Persian poet Rumi and now Blame it on Rahil. While he was on the panel, he was sketching cartoon, while the host was asking questions that Mohin had prepared, focused on the 90s cartoon themes. The questions were “[What was the] breed of Courage the Cowardly Dog?”, “Catchphrase of Flintstone”, and “Arch nemesis of Dexter”. His session finished by 2 PM.

At 2 PM, there was a session with AXN, and questions about AXN shows. Musician Shrey also played scores of various AXN shows on guitar, which audience had to guess. At 2:30 PM, there was a session with Cuban comic artist Vanesa Del Rey. She said it was her first convention in India, and said, “It is like any major convention in the US”. This year, Vanesa Del Rey was nominated for an Eisner Award. During the discussion, she said she wanted to do sci-fi epic,romance, mystery and thriller comics in future. Regarding romance genre in comics, she said it is “something worth exploring”. And regarding her career choice, she said her grandmother was an artist and her “family was very supportive”.

Later, there was a session with Sony PIX, with Minions appearing on the stage.

The event finished around 8 PM.

Possible under reporting of bird flu infections in China and other Southeast Asian countries may be promoting an illusory sense that human infections are very limited. Common press reports only describe fewer than 130 people as infected with H5N1 avian flu and that fewer than 70 have died worldwide. Yet, there are enormous problems getting accurate data, especially in a country like China with a population of more than a billion.

“Reporting a suspected bird flu infection in bird or humans is a very unlikely event,” said Dr. Shoshana Zimmerman of the eHealth Institute. She is also a founder of www.birdflubeacon.com, a site dedicated to bird flu issues. “There are very few incentives to report, and lots of reasons to refrain from reporting. From the viewpoint of local rural small farmers, there is little to be gained and much to be lost by reporting an infection. The worse threat is that their flocks could be killed, leaving them destitute.”

There are many factors which mitigate against reporting bird or human infections of bird flu.

• The deaths of chickens, ducks, and birds are common events for farmer. Even when a large number die at one time they may see no purpose in reporting the deaths.

• When a human dies in locations with little or no medical services, the rural farmer’s priority for discerning the cause of death may be low.

• In rural areas most people are not taken to hospitals when they are sick.

• Bird flu symptoms are not widely known. If the symptoms are not known, they will not be recognized and reports of possible bird or human infections can not be made.

• The expenses required for detection are those of proper collection and shipment of samples to one of approximately 200 laboratories worldwide, as well as the testing procedure that requires a two week period of waiting before results are obtained.

• The lack of incentive for countries to report large scale outbreaks as it may lead to widespread panic and economic loss, as occurred with SARS. These factors can be seen at work in the way that the first bird flu death was reported in China,” Dr. Zimmerman stated.

A young woman, Zhou Maoya, died after returning home to the village of Yantan in Annui province to prepare for her wedding. Her family has stated that they did not take her to the hospital because they thought it would not do any good. Officials also note rural Chinese also often cite relatively expensive medical costs as a reason for not seeking treatment when sick.

Although initially authorities attributed her death to pneumonia the resulting political pressure prompted China to invite the World Health Organization to send experts to investigate. The authorities then rescinded the previous position and attributed her death to bird flu based on the similarity of the symptoms that she was reported to exhibit with those of bird flu. The village was quarantined and journalists were denied access. It is not known how many others might be infected in the village. Official announcements were made of plans to vaccinate and cull birds.

A local government official, Fan Qian, told AFP that it was believed Zhou was infected while she was outside of the province.

Fan Tan, a local official, told AFP news that 1,000 birds in Yantan had been culled (killed). Plans were announced to vaccinate 2 million poultry in the area, a huge and difficult task.

Zhang, another official, said authorities had met with all villagers to give them flu vaccinations and to tell them how to protect themselves against the bird flu virus, including not consuming poultry products. It is known that flu vaccinations do not protect against bird flu.

Villagers and local officials minimized the threat. In outlying areas of Yantan, residents said that they did not know of any new outbreaks. Other possible infections have been attributed to similar common causes but there have not been any tests performed validating those attributions.

Fan Litan, a peasant woman from Fantu village, about 2 miles from Yantan, lost many of her ducks, and chickens and also a dog; she has attributed these deaths to the acts of hooligans. She said her family had been extremely frightened when her animals suddenly died. “We were scared to death,” said Fan, standing next to a red sign posted on the outside wall of her home that said: “Prevention and control by the masses is basic for people.” Fan said ducks and chickens are all healthy but she admitted that she had stopped eating poultry. No testing of these birds has been reported yet.

According to a recent AFP report from Liuchang, 59 miles south of Yantan, the obstacles to identifying infections are enormous.

Like many, one Liuchang villager named Wang Hemin said he was concerned and would keep a closer eye on his ducks and chickens, but felt no immediacy since the infection was not in his province. He learned about bird flu on TV, and is aware that officials have come to his village of 2,700 people to warn residents about the virus. They offered guidelines: they told people that poultry which die suddenly could have contracted bird flu and should not be eaten or sold and that such an incident should also immediately be reported. However, the symptoms of H5N1 bird flu were not directly described.

Residents have not yet been fully informed of what symptoms to look for in ill poultry–they are fever, diarrhea, teary eyes and swelling in the legs of the birds. Though a pledge was made earlier in the week to vaccinate 2 million birds immediately, no bird vaccinations in this area have been reported yet.

In another nearby village, Nazahuang, chickens scuttle in and out of houses. One resident, Fan Jiexu, 73, said no officials had yet warned her village to take precautions. Throughout rural areas, it is customary for chickens to scuttle in and out of homes. Ducks and bird often die and are eaten by villagers when it is believed safe to do so.

China has reported 17 avian flu outbreaks as of this week. Despite the Chinese government issued high alerts, critical information is not being adequately communicated to some rural villages. The size of the poultry population, the common and normal occurrence of poultry death on farms, and status of roughly 70% of the poultry population as being kept in backyards are factors complicating infection control.

The head of World Health Organization’s China office, Henk Bekedam, is aware that slow reaction to bird flu threats and difficulty monitoring poultry in the world’s most populous country makes control of its spread challenging.

Testing is required to confirm H5N1 virus, and positive test results lead to the killing of nearby flocks. The incentive for many villagers, officials, and governments to minimize reports of H5N1 virus infections and severe medical and economic complications for making confirmations of infection are obstacles opposing complete and full reporting of the spread and infection rates of the virus.

Sweden’s first royal wedding since 1976 took place Saturday when Crown Princess Victoria, 32, married her long-time boyfriend and former personal trainer, Daniel Westling, 36. The ceremony took place at Stockholm Cathedral.

Over 1,200 guests, including many rulers, politicians, royals and other dignitaries from across the world, attended the wedding, which cost an estimated 20 million Swedish kronor. Victoria wore a wedding dress with five-metre long train designed by Pär Engsheden. She wore the same crown that her mother, Queen Silvia, wore on her wedding day 34 years previously, also on June 19. Victoria’s father, King Carl XVI Gustaf, walked Victoria down the aisle, which was deemed untraditional by many. In Sweden, the bride and groom usually walk down the aisle together, emphasising the country’s views on equality. Victoria met with Daniel half-way to the altar, where they exchanged brief kisses, and, to the sounds of the wedding march, made their way to the the silver altar. She was followed by ten bridesmaids. The couple both had tears in their eyes as they said their vows, and apart from fumbling when they exchanged rings, the ceremony went smoothly.

Following the ceremony, the couple headed a fast-paced procession through central Stockholm on a horse-drawn carriage, flanked by police and security. Up to 500,000 people are thought to have lined the streets. They then boarded the Vasaorden, the same royal barge Victoria’s parents used in their wedding, and traveled through Stockholm’s waters, accompanied by flyover of 18 fighter jets near the end of the procession. A wedding banquet followed in the in the Hall of State of the Royal Palace.

Controversy has surrounded the engagement and wedding between the Crown Princess and Westling, a “commoner”. Victoria met Westling as she was recovering from bulemia in 2002. He owned a chain of gymnasiums and was brought in to help bring Victoria back to full health. Westling was raised in a middle-class family in Ockelbo, in central Sweden. His father managed a social services centre, and his mother worked in a post office. When the relationship was made public, Westling was mocked as an outsider and the king was reportedly horrified at the thought of his daughter marrying a “commoner”, even though he did so when he married Silvia. Last year, Westling underwent transplant surgery for a congenital kidney disorder. The Swedish public have been assured that he will be able to have children and that his illness will not be passed on to his offspring.

Westling underwent years of training to prepare for his new role in the royal family, including lessons in etiquette, elocution, and multi-lingual small talk; and a makeover that saw his hair being cropped short, and his plain-looking glasses and clothes being replaced by designer-wear.

Upon marrying the Crown Princess, Westling took his wife’s ducal title and is granted the style “His Royal Highness”. He is now known as HRH Prince Daniel, Duke of Västergötland. He also has his own coat-of-arms and monogram. When Victoria assumes the throne and becomes Queen, Daniel will not become King, but assume a supportive role, similar to that of Prince Phillip, the husband of the United Kingdom’s Queen Elizabeth II.

Robin Cook, the former British foreign secretary and current Member of Parliament, has died of a suspected heart attack after collapsing on a walk with his wife on Ben Stack hill, Scotland. Cook, aged 59, was flown to a hospital in Inverness by a rescue service helicopter half an hour after collapsing.

A spokesperson for NHS Highland said that Mr. Cook arrived at hospital 90 minutes after his collapse, and was reported dead five minutes later. A postmortem examination has concluded that he died from hypertensive heart disease.

Mr. Cook was buried on August 12 at St Giles Cathedral in Edinburgh in a service attended by close family, friends and political figures from across the world. British Prime Minister Tony Blair however came under attack from Mr. Cooks friend and racing pundit John McCririck for his absence from the service.

Robin Cook served as Foreign Secretary under New Labour and was a critic of the war in Iraq. He resigned as Leader of the House of Commons in 2003 in protest against Prime Minister Blair’s foreign policies.

Wikinews attended the sixth annual Mini Maker Faire in Tyler, Texas, United States on Saturday. Similar to a giant science fair, the event featured a variety of science, engineering and technology projects and items.

An array of technologies were on hand including 3D printers, drones, and various other physics devices. The owner of the Make Crate subscription service stated her company’s products place a strong emphasis on teaching young people about technology and coding. A traditional blacksmith was also on hand displaying metal working techniques.

Numerous Maker Clubs from an array of local schools were on hand, displaying a broad swathe of tech projects. A group of amateur hobbyists diplayed a model of the deck of the aircraft carrier, the USS Ronald Reagan with a solenoid device hooked up to launch paper airplanes.

Wikinews interviewed author Marc Headley about his new book Blown for Good, and asked him about life inside the international headquarters of Scientology known as “Gold Base“, located in Gilman Hot Springs near Hemet, California. Headley joined the organization at age seven when his mother became a member, and worked at Scientology’s international management headquarters for several years before leaving in 2005.

Wednesday, February 16, 2005According to computer security expert Bruce Schneier, a widely-used cryptography algorithm, known as SHA-1, has been broken by three researchers at Shandong University in China. Designed by the US intelligence agency NSA, SHA-1 has been adopted as an official US government standard and has become widely-used in security applications worldwide, notably digital signatures. The three female researchers, Xiaoyun Wang, Yiqun Lisa Yin, and Hongbo Yu, have reduced the amount of time needed to find two documents with the same signature by a factor of more than 2000.

The SHA-1 algorithm is used to compute a short string of numbers, known as a hash, for any digital document. The algorithm is constructed such that small changes in the document cause the hash to change drastically. By this means, the hash can be used to verify that a document has not been tampered with.

The attack that Schneier describes is a “collision attack,” rather than the more useful “pre-image” attack. In a pre-image attack, the codebreaker is able to find a document with different contents that matches an existing hash and so can claim an existing signature was on something else. In the somewhat less valuable “collision attack,” the codebreaker is able to devise two documents that both have some particular hash. A adversary might use this to claim that an altered document is the original on the grounds that they have the same hash. A crafty adversary might also be able to trick someone into signing an innocuous document, one of a pair from a collision. The other document, which might not be as harmless, would then also appear to have been signed by the same person. If collisions can be found for SHA-1, then digital signatures will no longer vouch for a document’s authenticity.

The attack, for now, is more of a theoretical than a practical kind: it would currently take thousands of years on a modern personal computer, and would still be slow even if a large number of computers were used in parallel.

Xiaoyun Wang is currently a professor at Shandong University, while Hongbo Yu is a doctoral candidate at the same institution. Yiqun Lisa Yin is currently a visiting researcher at the Princeton Architecture Laboratory for Multimedia and Security (PALMS). Last year, Xiaoyun Wang and Hongbo Yu also took part in breaking a series of similar algorithms, including the widely used MD5 hash, as documented in their paper presented at the Crypto 2004 conference.

Officials from the National Institute of Standards and Technology (NIST) have recently recommended dropping SHA-1 in favor of stronger, slower algorithms, such as SHA-256, Federal Computer Week reported on February 7, 2005, just 7 days before Schneier announced the SHA-1 break. Despite deprecating SHA-1, William Burr, the head of NIST’s security technology group, said that “SHA-1 is not broken, and there is not much reason to suspect that it will be soon.”

In an internet-based study published today on the website of the British Medical Journal, Australian investigators tested how well Googling could help to establish a difficult diagnosis. The search results met against their criteria in 15 out of 26 cases.

Previous anecdotes of the use of Google in reaching a difficult diagnosis are presented in the paper. In a case described in the New England Journal of Medicine (NEJM), a physician diagnosed IPEX syndrome after submitting the typical diagnostic clues to the search engine. A patient’s father replied to doctor’s saying that his son had acute subclavian vein thrombosis of unknown origin: “But of course hehas Paget-von Schrötter syndrome.”

Hangwi Tang and Jennifer Hwee Kwoon Ng from the Princess Alexandra Hospital in Brisbane selected clinical cases from the NEJM blind to the correct diagnosis. They selected 3 to 5 rather specific features, searched Google, and selected the 3 disorders from the results that seemed to fit the case best. If one of those was right, Google was said to be “right”.

The scientists admit that an internet search probably works better with specific symptoms rather than with phrases such as “fever ill pain”. Also, the percentage may depend on the operating physician’s knowledge base, and the test was not double-blind.

Experts commented that the internet is not a replacement for doctors, but should be seen as a way of supporting doctors and patients. A spokeswoman for the Patient Association added that “a lot of sites are not credible. There are lots of good sites out there, but we also know that there are many that are not credible.”
