Hundreds of thousands of air travelers had their travel plans disrupted in Europe by volcanic ash from the Eyjafjallajökull eruption.

Tens of thousands of air travelers were stranded when all flights into and out of the United Kingdom were grounded, as it became one of the first nations to be affected. The grounding was even more extensive than that following the September 11 attacks of 2001 when only trans-Atlantic flights were canceled.

Eurocontrol released a statement saying “…most air traffic in the United Kingdom, Ireland, Denmark, Norway and Sweden is suspended.”

The grounding is because the volcanic ash drawn into the jet stream is of a particle size which allows it to remain aloft in the atmosphere. Ingestion of this foreign matter, because of its distribution, would lead to flame outs in all aircraft engines. The composition of the ash also means that it would first melt into glass if it were to enter the engine of an aircraft before solidifying again as it cooled. This could lead to damage to the compressors and fan blades, which would make it impossible to restart the engines, even if the aircraft were to exit the cloud.

The current contingency is informed by the experience of British Airways Flight 9, which on June 24, 1982 suffered just such complete engine flame outs when it flew through the plume of Mount Galunggung in Indonesia. In that case, the flight crew after many efforts was able to restart the engines, though one failed shortly after, and the aircraft landed without casualties.

The UK National Air Traffic Services (NATS) has stated that “restrictions will remain in place in UK controlled airspace until 1300 (UK time) tomorrow, Friday 16 April, at the earliest,” and that “We will review further Met Office information and at 0230 (UK time) tomorrow we will advise the arrangements that will be in place through to 1800 (UK time) tomorrow.” The NATS statement concluded “…the situation cannot be said to be improving”.

In addition to Northern Europe, the ash is drifting south; Berlin and Hamburg airports in Germany are closed, and airports in the Netherlands, Belgium and Northern France are described as now being closed or closing. Some flights from Spain and Portugal, together with upwards of 4,000 flights across Northern Europe, have been affected, and the knock-on effect of aircraft and crews out of position could disrupt air travel worldwide for up to 72 hours.

One affected group are British musicians booked to play at this weekend’s Coachella Festival in California. Amongst those stranded are Frightened Rabbit, Gary Numan, The Cribs and Bad Lieutenant.

Tuesday, April 5, 2005Terry Vo, the 10-year old Australian boy who had two hands and a foot reattached by surgeons after losing them in an accident, has had to have the foot re-amputated. He will be given a prosthetic foot in its place.

The operation to re-attach three limbs was thought to have been a first – but was ultimately unsuccessful, with the foot having died inside, and receiving insufficient blood supply following the surgery to reattach it.

“That would lead to the small muscles in the foot actually constricting, the toes bending over and a deformed …. foot that is sort of clawed over and doesn’t have good sensation,” said plastic surgeon, Mr Robert Love today, on Australia’s ABC Radio.

“Even if you can get all of that to survive, he [would be] worse off than having had an amputation.”

“What is very disappointing is that for the first two days after [the operation] the foot looked absolutely magnificent,” he said.

Terry’s hands were healing well, said the surgeon. The prosthetic foot would allow him to walk normally, since his knee was intact.

Charles Eugene Flowers and Stephanie Bassitt, who run Love Demonstrated Ministries in San Antonio, Texas, United States, have been arrested and charged with aggravated assault for tying a girl to their van and dragging her behind it on her stomach.

The victim had stopped running with a group of campers, after falling behind. She says Bassitt yelled at her while Flowers tied her to the van.

The girl was treated for injuries on her stomach, legs and arms. She reported that this was the second assault. Flowers and Bassitt remain in jail on US$100,000 bond each.

Love Demonstrated Ministries is a 32-day Christian boot camp for girls whose parents feel they are “at risk teens”. Such camps have raised controversy before.

An organization called the International Survivors Action Committee maintains a list of U.S. organizations where numerous abusive incidents have been reported; however, their list should not be taken as exhaustive. Neither Love Demonstrated Ministries nor New Horizons Youth Ministries, which has an alumni site describing abuse appeared.

Ian Narev, the CEO of the Commonwealth Bank of Australia, this morning “unreservedly” apologised to clients who lost money in a scandal involving the bank’s financial planning services arm.

Last week, a Senate enquiry found financial advisers from the Commonwealth Bank had made high-risk investments of clients’ money without the clients’ permission, resulting in hundreds of millions of dollars lost. The Senate enquiry called for a Royal Commission into the bank, and the Australian Securities and Investments Commission (ASIC).

Mr Narev stated the bank’s performance in providing financial advice was “unacceptable”, and the bank was launching a scheme to compensate clients who lost money due to the planners’ actions.

In a statement Mr Narev said, “Poor advice provided by some of our advisers between 2003 and 2012 caused financial loss and distress and I am truly sorry for that. […] There have been changes in management, structure and culture. We have also invested in new systems, implemented new processes, enhanced adviser supervision and improved training.”

An investigation by Fairfax Media instigated the Senate inquiry into the Commonwealth Bank’s financial planning division and ASIC.

Whistleblower Jeff Morris, who reported the misconduct of the bank to ASIC six years ago, said in an article for The Sydney Morning Herald that neither the bank nor ASIC should be in control of the compensation program.

With five active cases of the Delta variant of COVID-19, South Australia begun a one-week lockdown on Monday. Announcing the lockdown, state Premier Steven Marshall declared “we have no alternative but to impose some fairly heavy and immediate restrictions”.

The first case out of South Australia’s active cases was presented to Modbury Hospital on Sunday night, having returned from Argentina earlier this month. The fifth, which Premier Marshall noted as “far more worrying”, visited The Greek on Halifax restaurant at the same time as someone who was later confirmed to be carrying the virus. Chief Public Health Officer for the state Nicola Spurrier said “if anyone has been at The Greek on Halifax they need to get into quarantine and get tested”.

In accordance with new regulations, there are only five reasons for South Australians to leave home: essential work, shopping for essential goods such as food, exercise, but only with people from the same household and within 2.5 kilometers (2 mi) of home, medical reasons (which includes testing and vaccination against the coronavirus, but excludes elective and cosmetic surgery), and caregiving.

Schools have closed for all but children of essential workers, with online learning having begun on Thursday. Face masks are also be mandated for those who leave home. ABC News reported that “support for businesses is expected to be announced…”, with all non-essential retail required to close under the new regulations.

In a new study released by the Florida Museum of Natural History on Monday, scientists report spiky skulls evolved at least 25 separate times in different kinds of frogs. The survey was reportedly to be published in Proceedings of the National Academy of Sciences.

Lead author Daniel Paluh, a Ph.D. candidate at the University of Florida, said, “Superficially, frogs may look similar, but when you look at their skulls, you see drastic differences […] Some of the weirdest skulls are found in frogs that eat birds and mammals, use their heads as a shield, or in a few rare cases, are venomous. Their skulls show how strange and diverse frogs can be.”

Some scientists had previously suggested smaller frogs would tend to develop spiky skulls, but that is not what this study reports. Here, researchers evaluated CT scans on 158 different species. They found frogs that had similar ecological niches — meaning they either acquired food in the same way or defended themselves from predators in the same way — tended to develop skulls with similar grooves, spikes, or specialized jaw joints regardless of whether they were ancestrally related to each other.

According to the study, skulls with spikes, grooves or ridges — called hyperossification — often accompanied frogs eating very large prey relative to their own body size. The strong, spacious skulls would allow the frogs to have very big mouths with which to catch birds, rodents, reptiles and other frogs. Spikes sometimes coincided with venomous frogs. The researchers speculated the spikes make it dangerous for predators to hit the frog’s head, as the spikes would break venom sacs under the frog’s skin.

Other bone formations included projections resembling fangs or lower teeth that different species of frogs use for catching prey and fighting. Very few frogs have true lower teeth.

One of the study’s authors, herpetologist David Blackburn, told Discover Magazine the frequency of spiky skulls evolving in otherwise unrelated frogs suggested some deep pattern frogs fell into as circumstances arose: “Somehow, these frogs are turning on some ancient developmental machinery in their DNA.”

Since 1973, when frogs skulls were last comprehensively surveyed, scientists have documented enough new species to double the number known to humans. Also, modern techniques exploit CT scans, of which Paluh and his team made liberal use. The research was part of the oVert project, funded by the National Science Foundation, meant to comprehensively CT-scan over 20,000 vertebrate specimens from United States museums.

News emerged yesterday that Boko Haram Islamists are suspected to have killed 44 worshippers during dawn prayers early Sunday morning in the small town of Konduga in Nigeria. The attacks were believed to be a revenge on citizen vigilante groups forming to help the government battle Islamist extremists and occurred 35km from the state capital Maiduguri.

A further 26 people are being treated for severe injuries. Boko Haram’s insurgency has killed at least 3,600 people since 2009, including killings by security forces.

In recent weeks the military has encouraged the formation of vigilante groups to help locate and arrest members of Boko Haram. Boko Haram has attacked churches and mosques. A video has been released where Boko Haram’s leader Abubakar Shekau takes responsibility for the attacks.
