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.”

According to media reports, a Colombian air force AC-47 (registration FAC1670) spy plane carrying five people has crashed near the Colombian city of La Dorada, in the department of Caldas.

All on board the plane are believed to have been killed, according to Colombia Reports. Among the dead, according to Monsters and Critics, are two technicians, a major and two second lieutenants. ABS-CBN News reports that the dead included three high ranking officials and two lower ranking ones.

Jorge Ballesteros, a Colombian air force official, says that the plane took off from an air force base in the city of Puerto Salgar and was on an exercise mission when it crashed. He also states that although it was on a training exercise, the plane was carrying bombs and machine guns.

A military team has been dispatched to the area to investigate the incident, but they have already put the blame on mechanical failure. Ballestero noted that investigators have ruled out a rebel attack and terrorism as possible causes.

AC-47’s have been used by the Colombian air force for nearly 20 years, most of which were donated from the United States. They were provided to the country in an attempt to fight the illegal drug market and to defend citizens and the military against rebel attacks. They are also used to gather intelligence and come equipped with a state-of-the-art communications system, radar and infrared detection systems.

Local residents of Dungog, a small country town in New South Wales (NSW), Australia, held a celebratory nature walk on Sunday after they received assurance that their local forest was deemed worthy of “enduring protection.” Previously, a proposal before the NSW government to log over one million hectares of protected national park forests had caused alarm among nature conservationists.

To celebrate the continued protection of national parks in NSW, a free guided walk was held on Sunday in the Black Bulga Range Conservation Area. This family-friendly nature ramble meandered along the mountain’s ridge, with locals enjoying the forest, sharing a cup of billy tea and knowledge about the local forest’s ecology and history. The physical presence of the locals in the forest demonstrated their continued use of this area and the importance of national parks for the community.

Since early 2012, the possibility of logging for commercial timber in NSW national parks had been emerging. A state government inquiry on the management of public land in NSW received submissions and evidence from both the Australian and NSW Forest Products Associations (FPA). The FPA’s recommendation to “tenure swap” between national parks and state forests in order to sustain the timber industry were included in the final governmental report.

The process began in April 2012 when the NSW Legislative Council —the upper house of the parliament of NSW— established an inquiry into the management of public land in New South Wales, conducted by the General Purpose Standing Committee No. 5. According to a media release from the Legislative Council at the time, the primary purpose of the inquiry was to “scrutinise the management of the State’s public land and review the process and impact of converting Crown Land, State Forests or agricultural land into National Park estate.”

By August that year, the committee had received a recommendation from Mr. Grant Johnson of the Australian Forests Products Association for the “re-introduction of harvesting activities in forest areas previously set aside for conservation.” The following month, Mr. Johnson and Mr Russell Alan Ainley, Executive Director, NSW Forest Products Association, were invited before the committee. At this hearing, the chair, Mr. R. L. Brown, member for the Shooters and Fishers Party, asked Mr. Ainley for “a calculation of the area currently in [national parks] reserve that would need to be returned [to state forest] to be available for timber extraction”. In response, Mr. Ainley suggested “a little more than one million hectares.”

On May 15, the NSW Legislative Council published a Final Report on the management of public land in New South Wales. Among its key recommendations was that “the NSW Government immediately identify appropriate reserved areas for release to meet the levels of wood supply needed to sustain the timber industry, and that the NSW Government take priority action to release these areas, if necessary by a ‘tenure swap’ between national park estate and State forests. In particular, urgent action is required for the timber industry in the Pilliga region.”

A “tenure swap” would reserve areas of NSW state forest where logging is now allowed, in exchange for opening areas of national parks for logging.

Environment groups such as The Nature Conservation Council of NSW and The Wilderness Society announced that these government documents signaled an immediate threat of logging in national parks in NSW. This information raised concerns of other community and activist groups because logging is not conducted in national parks in Australia. According to the NSW Department of Environment, Climate Change and Water, a national park is an area designated to “protect Australia’s plants, animals, ecosystems, unique geology and Aboriginal and non-Aboriginal cultural connections to the land.”

The Black Bulga State Conservation Area was one of many parks listed by the environment group Save Your National Parks as potentially vulnerable for “tenure swap”. This forest covers 1554 hectares and connects Dungog Shire to the World Heritage listed Barrington Tops National Park, part of a green corridor from the ocean to the mountains.

Residents living near the forest were concerned by the proposal for logging in their area. A local information day held in June, at the Settlers Arms, Dungog, motivated local action. As a consequence of the event, over forty hand-written letters were posted to the Premier and local MPs. In a recent reply from the NSW government, the Minister for the Environment, Robyn Parker, stated: “The Government does not support commercial logging in national parks and reserves, including Black Bulga State Conservation Area, and has no plans to allow it. The NSW Government recognises that our national parks and reserves are special and unique places that deserve enduring protection. The Government is committed to their important role in conserving native flora and fauna and cultural heritage, and to improving community well-being through increased opportunities for recreation and tourism”.

As reported in the Dungog Chronicle, Jo New of the Black Bulga Range Action Group was thrilled by the government’s response to a community-driven campaign. “It goes to show what a wonderful impact local people can have after they do something simple, like posting a letter”.

Yesterday February 17, 2006, the World Health Organisation officially declared presence of the H5N1 strain of the avian flu virus in Egypt.

“There is avian flu now in Egypt,” Hassan el Bushra, regional adviser for emerging diseases at the eastern Mediterranean regional office of the WHO said. His response was to the reported presence of H5N1 virus in dead birds in three areas in Egypt – namely Cairo, Giza, and Al-Minya.

Today February 18, 2006, a responsible source from Egyptian ministry of health announced reporting of another 25 cases of infected birds in Al-Minya with aftermath of 35 confirmed cases between birds, yet there are no human cases reported.

Egypt has banned the import of live birds and has tightened quarantine controls at airports to keep out bird flu. It has also canceled the annual bird hunting season to minimize contacts between people and migrant birds.In Cairo phone numbers 3912136, 3907147, and the hotline 152 have been assigned for reporting any suspected cases. A newly formed unit formed of veterinarians and preventive medicine specialists in Giza actively studying more than 70 reports of dead birds for exclusion of H5N1.

Egyptian Prime Minister Ahmed Naxif has advised people who breed poultry at their homes to dispose of their birds to prevent the virus from spreading.

“The time has come to get rid of the idea of breeding chickens on the roofs of houses, especially under current circumstances,” he said.

Many Egyptian citizens breed chickens and pigeons on the roof of their residences for their own consumption and as a source of extra income.

Despite avian flu mainly being a disease of poultry, it has also infected 171 people, killing 93 of them, and is steadily mutating. If it acquires the ability to pass easily from person to person it could cause a pandemic that might kill millions.
