In the year 2000, Dries Buytaert created Drupal, a freely licensed and open source tool to manage websites, as a bulletin board for his college dorm. Since Dries released the software and a community of thousands of volunteer developers have added and improved modules, Drupal has grown immensely popular. Drupal won the overall Open CMS Award in 2007, and some speakers in Drupal’s spacious developer’s room at FOSDEM 2008 were dreaming aloud of its world domination.

Buytaert (now 29) just finished his doctoral thesis and has founded the start-up Acquia. The new company wants to become Drupal’s best friend, with the help of an all-star team and US$7 million collected from venture capitalists. Wikinews reporter Michaël Laurent sat down with Dries in Brussels to discuss these recent exciting developments.

A man who fell ill after participating in a drug trial at Northwick Park Hospital in north-west London earlier this year has revealed he has the early signs of an “aggressive” form of cancer.

David Oakley was one of six men who volunteered to take part in a trial of a drug intended to cure conditions like rheumatoid arthritis and leukemia in March. But after taking the drug, the thirty-five year-old suffered multiple organ failure and prominent inflammation.

Mr Oakley, who lives in west London, told today’s Mail on Sunday that doctors have informed him he has “definite early signs” of lymph cancer. He also fears he could develop other debilitating illnesses like rheumatoid arthritis, multiple sclerosis, chronic fatigue syndrome and lupus. He will now undergo tests to see what treatments will be required. “It’s very frightening,” he told the newspaper. “I’m trying not to be too down about the thought of having chemotherapy or that I might die.”

Mr Oakley was paid £2,000 for his involvement in the trial, and that money subsidised his marriage to wife Katrina in June. He now fears their hope of having children has been jeopardised as a result of his ill health. “Katrina and I had planned to start trying for children six months after getting married, but we can’t do that now. Everything is on hold.”

There is nothing to suggest that Mr Oakley’s cancer was triggered by the experiment. He is now seeking compensation from Parexel, the company which organised the drug trial. “Really, I’m just trying to do my bit and pointing out their mistake. If someone doesn’t point it out it could happen again and there’s no way I would like to see someone else go through what we’re going through right now.” Earlier this year, six men had to be admitted to an intensive care unit at the same hospital, in another Parexel drug trial which caused much upset.

An earthquake with a magnitude of 5.9 was detected on Wednesday in the Australian town of Mansfield, which is located in the north-east of Victoria. Geoscience Australia stated the earthquake was recorded in Mansfield at 9:15am local time with a 10 kilometers (6 mi) depth. An estimated 15 minutes after the initial event, an aftershock of 4.0 magnitude occurred near Mansfield. The agency declared the earthquake is one of the largest to occur since colonisation in east Australia.

The earthquake was felt across the country, with over 15,000 recording on the Geoscience Australia website they had felt it. ABC News reported the earthquake was felt in the states of Victoria, New South Wales (NSW), South Australia, and Tasmania, as well as the nation’s capital of Canberra. In the inner suburbs of Melbourne, apartment buildings were evacuated, with reports of building and road damage shared on social media. Local authorities confirmed there was no risk of tsunamis.

Fire and Rescue New South Wales “dispatched crews across NSW from Alexandria, Manly and Hornsby in Sydney to as far as Dubbo in Western NSW following reports of tremors felt across the state” as a result of the earthquake, though no major structural damage was reported in New South Wales.

Karen McGregor, an employee of FoodWorks in Mansfield, reported “the windows started shaking, the walls, and everything on the desk, it was really quite scary. We ran downstairs to the shop, it was really, really scary down there. The windows were buckling. I was very scared. I just thought, oh my God, is this place going to fall down?” McGregor added she had not heard of any injuries in the town.

From Washington, D.C., Australian Prime Minister Scott Morrison said “it can be a very, very disturbing event for an earthquake of this nature. They are very rare events in Australia and, as a result, I am sure people will have been quite distressed and disturbed by that.” Morrison confirmed he was in contact with Victorian state Premier Daniel Andrews, and the Australian federal government was prepared to provide support to Victorians where needed, including the possibility of deploying the Australian Defence Force if necessary.

While Geoscience Australia initially reported an earthquake with a magnitude of 6.0, the head of the Seismology Research Centre Adam Pascale has said “we think it’s a mag-5.8 potentially at this point in Gippsland”, adding the earthquake “shook here in the northern suburbs of Melbourne for about 15-20 seconds so it’s quite a significant earthquake”. Geoscience Australia has since revised the magnitude to 5.9.

Further aftershocks remain a possibility, with Pascale saying “there’s usually a primary and a secondary wave”, and geoscientist Mark Quigley telling The Age “for something of that size, we’re talking about a fault that would be on the order of maybe 5 kilometres long and three kilometres wide. For an earthquake of that magnitude, we would expect to get hundreds of small aftershocks. We could get aftershocks in the range of 4.5 magnitude.”

Last Thursday, British sensory biologist Dominic Clarke and other authors published research about detection of floral electric fields by bees in journal Science. The research involved studying bees’ reaction to flowers with different electric fields. The researches concluded that bees can choose flowers based on their electric fields, and remember them as they do with color and other characteristics of flowers.

This Friday Wikinews interviewed Dominic Clarke about the research.

((Wikinews)) What caused your initial interest in electric fields of flowers?

Dominic Clarke: There has been a considerable amount of speculation in the scientific literature since the 60s about the role of electric fields in pollination. It has been suggested that the electric field that arises between a charged bee and a grounded flower may be responsible for increasing the efficiency of pollen transfer between the two. We looked at this literature as sensory biologists and naturally formed the question ‘can bees sense these fields?’. Since we couldn’t find any answers to that question in the literature, we decided to find out for ourselves.

((WN)) How was the new phenomenon discovered?

DC: We use what’s called ‘differential conditioning’, where bees are trained to find a sucrose reward from an array of flowers, where only half of the flowers contain the reward. In our experiment, the flowers that were rewarded (with a sugary solution) were marked with a small electric field (about the same strength as around a flower in the wild). The ones that were not rewarded were not marked with fields. Since the electric field is the only thing that differs between the two flowers, we know that if the bees can learn to tell them apart, they can sense the electric field. Our bees were able to pick the rewarded flower 80% of the time when the electric field was present as a cue. When the electric field was switched off, they could only get it right half the time, which is the same as if they were just picking flowers at random.

((WN)) How many species of flowers and bees did you study during your research?

DC: We focus on one species of bee, the bumblebee Bombus terrestris. And we look mainly at Petunia flowers (P. integrifolia). These two species provide the bulk of our data, but we do consider other flowers like geraniums, daisies, clematis and foxglove, and other species of bee (particularly the honeybee Apis mellifera).

((WN)) Do you have diagrams, sketches, or drawings of electric field around a bee and a flower?

DC: I have attached a picture of a computer model of the electric field around a flower called “Flower Potentials and Fields”.

((WN)) Was it known that bees have a charge before?

DC: Yes, reports as early as the 70s have measured electrical charge on bees, but it was not known before whether or not they could sense such charges.

((WN)) What environment did you study the flowers and bees in? A laboratory? A garden? Natural environment?

DC: The behavioural tests were carried out in a laboratory because we needed to be able to precisely control the environment in which the bees were tested. Future work will be aimed at trying to get out into the bees’ natural environment and trying to figure out exactly what role(s) this sense plays in their lives.

((WN)) What equipment was used during the research? How did you measure the charge?

DC: Charge was measured using a device called a “Faraday Pail”. It is basically an electrically shielded metal cup, the voltage of which changes according to how much charge is inside it. We can measure this voltage when a bee flies in and so measure its charge. We did this with 51 individual bees.

((WN)) What were the roles of the people involved in the research? What activity was most time-consuming?

DC: It was very collaborative in all aspects of the research. I carried out the bulk of the experimental work and data analysis, but the process of designing the experiment, figuring out how to do the analysis, choosing which ideas to follow and which to put on the shelf etc., that is highly collaborative. Then of course comes the long period of writing, re-writing, re-re-writing, sending out to colleagues for feedback, re-re-re-writing, submission, peer-review, editing re-submission etc. which is also a collaboration between all the authors. A large part of doing science is talking as well; meeting, planning brainstorming. It feels to me like putting together the paper took the longest, but perhaps that’s just because it’s the most fresh in my mind.

((WN)) What do you see as possible directions for future research in this field? What do you think possible applications of the discovery can be?

DC: The two big questions now are “how do the bees do this?” and “why do they do this?”. The first is a case of pinning down the sensory mechanism used by the bees to detect the fields, and the second will involve a great deal of field-based experiments. We need to get out of the laboratory and understand the role this phenomenon plays in the lives of bees in the wild.

((WN)) Thank you for sharing your insight and details. Have a good time.

Los Angeles County prosecutors have brought three felony charges against Stephen Heller for stealing documents from his employer, the law firm Jones Day.

The legal documents discussed the legal ramifications of activist allegations that Diebold Election Systems had used uncertified voting systems in Alameda County elections beginning in 2002. Jones Day represented the controversial electronic voting machine manufacturer at the time. The firm’s lawyers concluded that if such uncertified systems were used, then Diebold could be sued by Alameda County for millions of dollars. The memos also discussed whether the California’s secretary of state had the authority to investigate Diebold.

Mr. Heller has been charged with felony access to computer data, commercial burglary and receiving stolen property. He has pled not guilty.

Blair Berk, Heller’s attorney said, “It’s a devastating allegation for a whistle-blower. Certainly, someone who saw those documents could have reasonably believed that thousands of voters were going to be potentially disenfranchised in upcoming elections.”

Australian Prime Minister, John Howard appeared before the Cole inquiry on Thursday, the first time an Australian Prime Minister has appeared before an inquiry with royal commission powers since 1983.

Unlike his foreign minister Alexander Downer who gave evidence before the inquiry on Tuesday, Mr Howard entered through the front door where he gave a brief address. He told the press that his government is being open about the Iraqi kickback affair. ” just want to make one point and that is that the appearance by me, earlier this week by the Foreign Minister and also by the Trade Minister, demonstrates absolutely how open and transparent and accountable the Government is being in relation to this matter” Mr Howard said to reporters.

Mr Howard was questioned by John Agius, counsel assisting the inquiry. Counsel for AWB, the company at the centre of the scandal did not apply to cross-examine the prime minister.

Terrence Cole, the inquiry’s commissioner received an application from Peter Geary and Micheal Long’s counsel to cross-examine the prime minister but refused it on the grounds that the proposed line of questioning was similar to that of Mr Aguis’ and that there was no evidence that Mr Howard had “ever met with Mr Geary or Mr Long”.

Mr Agius questioned the prime minister about a series of diplomatic cables sent to his office, which raised concerns about AWB’s contracts in Iraq.

Mr Howard told the inquiry that he doesn’t recall reading or being briefed about any of the cables referred to by the inquiry. The inquiry also heard that prior to 2003 there was no system in place to identify which cables had been bought to the prime minister’s attention.

In his statement to the inquiry, Mr Howard said that his office had not received four of the cables mentioned by the inquiry. Under questioning, Mr Howard confirmed this but conceded that it was likely that his staff had read the other 17.

When asked whether there were any guidelines which guided his advisors in deciding which cables should be bought to the prime minister’s attention, Mr Howard replied “No, there weren’t”.

The inquiry heard that the only discussions about which cables which should be bought to Mr Howard’s attention occurred when an advisor changed in very generic terms. Mr Howard told the inquiry that he would tell a new advisor “Well, you’ve got to exercise your own judgment, I can’t possibly read everything, and clearly I want things brought to my attention which are, in your judgment, important and are relevant to issues in front of the government at the time”.

Mr Howard admitted that the government had an interest in Iraq using the United Nations oil for food program for its own financial benefit, but said he did not expect cables dealing with alleged breach of UN sanctions to have been bought to his attention.

The questioning then turned to a statement Mr Howard made to the National Press Club on March 13, 2003, one week prior to the US-led Iraqi occupation. Speaking about Saddam Hussein Mr Howard said “He has cruelly and cynically manipulated the United Nations oil-for-food programme. He’s rorted it to buy weapons to supporthis designs at the expense of the wellbeing of his people”.

Mr Agius asked Mr Howard if his statement was based upon briefngs he had received. Mr Howard told the inquiry that the information was based upon “open source” intelligence stated at addresses by British foreign secretary Jack Straw and the United States state department. Mr Howard said one of his advisors “checked with some cables to confirm that those cables supported the open-source claims and was satisfied that they did”.

Mr Howard denied seeing the cables used by the advisor to support the claims, but believed he would have told her to be sure that everything they were saying can be supported by fact. Mr Howard told the inquiry that he never knew about cables which referred to Hussein rorting the UN Oil for Food program. Mr Howard admitted that at the time his “general knowledge” was that Hussein had breached UN sanctions and was rorting the Oil for Food program.

“My general knowledge at the time and belief was that the program had been rorted, and it was not seriously in dispute. Nobody was arguing it hadn’t been rorted” Mr Howard said.

The prime minister was questioned about an unassessed intelligence report which mentioned a Jordanian trucking company known as “Alia” paying kickbacks to Hussein. In response to this Mr Howard told the inquiry that he could not recall the information being bought to his attention, which was not unusual.
