According to local police chief Craig Van Breugel there were no injuries or loss of life to animals or local residents in the recent fire in the rural Australian town of Toongabbie. “There was no injury to persons or animals. That is all I have for you,” Detective Acting Sergent Van Breugel said in response to queries from Wikinews.

The fire began about 2:20 pm local time (UTC+11) between Humphrey and Eagle Hawk roads, north of the township proper. The local Country Fire Authority brigade managed to contain the blaze to approximately three to five hectares.

Victoria Police have recently indicated that the area around where the fire was started is only accessible by four wheel drives (4WD) or off-road motorcycles; it is popular with dirt bike riders and 4WD enthusiasts.

The local Country Fire Authority brigade managed to contain the blaze to approximately three to five hectares between Humphrey and Eagle Hawk roads.

Det.Act.Sgt Van Breugel confrimed that there wer some off road motor cyclists in the are that day. “[Police] know there was a number of off road motorcyclists in the area on the day. Some of [them] have already been spoken to by the Police” Det.Act.Sgt Van Breugel said.

The fire is being treated as suspicious and people with infomation that may help the investigation are encouraged to contact Crime Stoppers or the local police.

Massive blackouts occurred throughout the US state of Florida shortly after 1:00 p.m. Eastern Time (18:00 UTC) on Tuesday afternoon. Out of the 4.4 million customers served by Florida Power & Light, Co. (FPL), about 680,000 residents were affected, with an additional two million-plus customers affected in other parts of the state. It is estimated that as many as four million customers throughout Florida were affected, with many different power companies losing control of their specific grids.

Power outages were reported as far south as the Florida Keys, on the original FPL grid, and as far north as Orlando and Daytona Beach, nearly 300 miles (483 km) away on the Progress Energy grid. Most of Miami-Dade and parts of Broward and Palm Beach counties suffered the worst outages.

FPL President Armando Olivera said that a disconnect switch failed at 1:08 p.m. at the automated substation west of Miami, and a piece of equipment that controls voltage caught fire about the same time. Neither failure by itself would have caused a widespread outage. The event at the utility’s Flagami substation consequently led to the rolling blackouts.

Originally the first failure was thought to have occurred at the utility’s nuclear plant at Turkey Point. It is still unclear how failure at this site spread, but with power turning off at the main Turkey Point location, which serves all of south Florida, FPL’s grid shut down as well. It contributed to a domino effect which ended up sapping energy from bordering grids all over Florida.

Police reported several people were stuck in the elevators of high-rise buildings in downtown Miami and several hospitals were running on backup power, although no injuries or fatalities have been reported. The blackouts caused major traffic jams and a few accidents, but the original outage was contained shortly after it occurred. All customers affected had power restored to them by 6:30 p.m. (23:30 UTC).

Dozens of students and teachers were stung by yellow jacket wasps Monday at a middle school in Cranston. The attack occurred around 10:45 a.m., according to Ray Votto, the chief operating officer for Cranston Public Schools.

It is suspected that during a routine fire drill, students exiting the building disturbed the wasps’ nest in a field behind the school. Votto said, “When kids exited towards the back of the school building near our portable classrooms, they walked into a field and may have disrupted a nest”.

The Cranston Fire Department and school nurses responded to the scene to provide medical assistance. A total of 25 students, one of whom was hospitalized, and four teachers were stung, some multiple times. All of the students and one teacher were sent home.

Dutch researchers have discovered that cabbage volatile odour released in response to white butterfly caterpillar attack can attract multiple parasites making the food chain unbeneficial to the plant. The study, published in journal PLOS Biology Tuesday, highlights the possible side effects of parasitoid use for pest control.

A second parasite, called hyperparasitoid, is attracted by the cabbage odour only after a first parasite infects the caterpillar. The researchers performed both laboratory and field experiments to verify the data.

As described by the study, the food chain starts when a white butterfly caterpillar, Pieris rapae, attacks a cabbage leaf. In response, the cabbage releases volatile odour to attract the caterpillar parasites. The odour attracts parasitical wasps, such as Cotesia glomerata, that infect the caterpillar with their eggs. Such behaviour is called parasitoid, when larvae lead a parasitical lifestyle and the adult individuals don’t. Such reaction favours the plant.

However the odour also attracts a hyperparasitoid wasp, Lysibia nana, which infects the Cotesia glomerata’s larvae and takes over the food chain. Field study confirmed the hyperparasitoid’s behaviour is well tuned to the environment: it does not follow cabbages nearly as much until they are infected by the first parasite, too.

Dr Erik Poelman, the research leader, commented about the specifically well adapted behaviour of the parasitoids, “In controlled laboratory assays as well as under field conditions, hyperparasitoids were offered plant odours coming from two types of plant: ones damaged by healthy caterpillars, and ones damaged by parasitoid-infected caterpillars. We found that they preferentially detected odours of plants damaged by infected caterpillars. We were excited by these results as they indicate that hyperparasitoids rely on a network of interactions among plant, herbivore and parasitoids to locate their host”.

The scientists hypothesised the saliva of infected caterpillars is different and affects the cabbage odour. The study involved collecting air around healthy, infected, and twice infected cabbage plants. Then the researchers checked the hyperparasitoid reaction to the collected odours. The hyperparasitoid attraction to the twice infected cabbage odour was nearly five times more compared to the odour of a cabbage infected only with caterpillars.

The researchers also carried out tests of hyperparasitoid attraction to the healthy and infected caterpillar saliva alone, without the cabbage. There was no such attraction, confirming the cabbage odours are affected by the saliva.

The scientists say, “Our results show that hyperparasitoids may parasitize up to 55% of the parasitoid offspring, therefore potentially playing a major role in parasitoid population dynamics. … Overexpression of herbivore-induced plant volatiles [HIPVs] in crops or field application of synthetic parasitoid attractants may not benefit pest control in conditions where the responses of hyperparasitoids to HIPVs cause major mortality to parasitoids.”

MiniMax Discount, a recently-established joint venture between several Romanian and foreign investors, will open its first three discount stores between today and April 28. The discount stores, which will be similar to supermarkets, will open in the southern Romanian cities of Slatina, Urziceni and Târgovi?te. MiniMax invested 750,000 euro per outlet, with each store having 1,000 m² of floor space and a parking area for 100 cars. The first store to be opened will be the one in Slatina, with the other ones opening by April 28.

The company is planning to open a total of ten stores this year, as well as another twenty in 2006. It is expected that most of the stores will open in small- to medium-sized cities, of greater than 20,000 inhabitants, rather than larger cities of over 150,000 inhabitants. In a few years time, it has said that it plans to extend its network to over 100 stores.

Challenger Freman Hendrix has upset incumbent Detroit Mayor Kwame Kilpatrick in the August 2 Detroit mayoral primary election. The top two contenders will face each other in the general election on November 8. Kilpatrick, the youngest mayor in Detroit history, is seeking his second term.

The Detroit Free Press reports that with 664 of the city’s 720 precincts reporting (92 percent), Hendrix had 44 percent of the vote, Kilpatrick had 34 percent, City Councilwoman Sharon McPhail had 12 percent, and state Sen. Hansen Clarke had 9 percent. Eight also-rans accounted for the remainder of the vote.

The results closely agree with an exit poll by local TV station WDIV and Mitchell Research, which had challenger Hendrix as the winner with 46 percent of the vote, Kilpatrick with 30 percent, McPhail with 11 percent, while state Sen. Hansen Clarke rounded out the top four with 9 percent. Mitchell Research & Communication’s pollsters interviewed 600 people who said they voted. The poll had a margin of error of plus or minus 4 percentage points.

Australian Minister for Vocational Education and Training, Gary Hardgrave has announced the government will provide AU$15.8 million to establish an Australian Technical College in North Adelaide. The minister said the government was entering into a partnership with the Archdiocese of Adelaide and consortium of industrial and manufacturing companies.

The North Adelaide college will be located in Elizabeth and be operated as an independent non-government school. The college is one of 25 to be established across the country.

Enrolments at the college will begin in 2007 and will offer courses in areas where identified skills shortages exist in the North Adelaide region, specifically – engineering, construction, electronics and cooking.

Mr Hardgrave said that the proposed college had been popular among the North Adelaide business community. “This important initiative has been well received by North Adelaide business and industry, and will help to address skills needs and provide opportunities for those in greatest need, including a lot of Indigenous students in the region,” Mr Hardgrave said.

“The fact that this College is being led by local employers, local government and other key stakeholders, means it will be truly industry and community driven,” he said.

Australian Technical Colleges were established to cater for year 11 and 12 students who wish to do an apprenticeship as part of their school education.

The Australian Education Union has expressed a number of concerns about the model put forward by the government. In a report, they claim that trade facilities at TAFE colleges (operated by state governments) will deteriorate as funding is diverted to the ATCs. The union is also concerned that ATCs are supposed to be selective VET schools. According to the union they will have selective entry and preferential funding. It is feared that teachers will be lured away from schools and TAFE colleges to higher paid positions in ATCs.

The Education Union suggested that the government invest in schools that already offer vocational education programs.
