Before the annual Earth Day on April 22, several environmental-related events were progressively promoted in Taiwan. For example, industrial and academical units promoted several energy-efficiency policies, parts and accessories, and products in three recently-closed trade shows (AutoTronics Taipei, Motorcycle Taiwan, and Taipei AMPA) respectively located at TWTC and TWTC Nangang with the international environmental laws and policies promoted in several nations including Taiwan. Taiwan Railway Administration promoted “Twin-rail Environmental Train” (in Chinese: ??????) for bicycle and mass transportation industries. And also, HBO Taiwan promoted the movement of “Decreasing chopsticks to save the earth” (in Chinese: ?????) to drive the public changing habits on common food habits when using environmental tablewares.

By the way, he also commented on the upcoming event of “Taiwan Bicycle Day” and “Project of Light-weighted Electronic Vehicle” by ITRI and said:

In late 2010 a geological expedition to Antarctica drilled through the Ross Ice Shelf so they could send an ROV under it. What they found was unexpected: Sea anemones. In their thousands they were doing what no other species of sea anemone is known to do — they were living in the ice itself.

Discovered by the ANDRILL [Antarctic Drilling] project, the team was so unprepared for biological discoveries they did not have suitable preservatives and the only chemicals available obliterated the creature’s DNA. Nonetheless Marymegan Daly of Ohio State University confirmed the animals were a new species. Named Edwardsiella andrillae after the drilling project that found it, the anemone was finally described in a PLOS ONE paper last month.

ANDRILL lowered their cylindrical camera ROV down a freshly-bored 270m (890ft) hole, enabling it to reach seawater below the ice. The device was merely being tested ahead of its planned mission retrieving data on ocean currents and the sub-ice environment. Instead it found what ANDRILL director Frank Rack of the University of Nebraska–Lincoln, a co-author of the paper describing the find, called the “total serendipity” of “a whole new ecosystem that no one had ever seen before”.

The discovery raises many questions. Burrowing sea anemones worm their way into substrates or use their tentacles to dig, but it’s unclear how E. andrillae enters the hard ice. With only their tentacles protruding into the water from the underneath of the ice shelf questions also revolve around how the animals avoid freezing, how they reproduce, and how they cope with the continuously melting nature of their home. Their diet is also a mystery.

E. andrillae is an opaque white, with an inner ring of eight tentacles and twelve-to-sixteen tentacles in an outer ring. The ROV’s lights produced an orange glow from the creatures, although this may be produced by their food. It measures 16–20mm (0.6–0.8in) but when fully relaxed can extend to triple that.

Genetic analysis being impossible, Daly turned to dissection of the specimens but could find nothing out of the ordinary. Scientists hope to send a biological mission to explore the area under the massive ice sheet, which is in excess of 600 miles (970km) wide. The cameras also observed worms, fish that swim inverted as if the icy roof was the sea floor, crustaceans and a cylindrical creature that used appendages on its ends to move and to grab hold of the anemones.

NASA is providing funding to aid further research, owing to possible similarities between this icy realm and Europa, a moon of Jupiter. Biological research is planned for 2015. An application for funding to the U.S. National Science Foundation, which funds ANDRILL, is also pending.

The ANDRILL team almost failed to get any samples at all. Designed to examine the seafloor, the ROV had to be inverted to examine the roof of ice. Weather conditions prevented biological sampling equipment being delivered from McMurdo Station, but the scientists retrieved 20–30 anemones by using hot water to stun them before sucking them from their burrows with an improvised device fashioned from a coffee filter and a spare ROV thruster. Preserved on-site in ethanol, they were taken to McMurdo station where some were further preserved with formaldehyde.

((Wikinews)) How did you come to be involved with this discovery?

Marymegan Daly: Frank Rack got in touch after they returned from Antarctica in hopes that I could help with an identification on the anemone.

((Wikinews)) What was your first reaction upon learning there was an undiscovered ecosystem under the ice in the Ross Sea?

MD I was amazed and really excited. I think to say it was unexpected is inaccurate, because it implies that there was a well-founded expectation of something. The technology that Frank and his colleagues are using to explore the ice is so important because, given our lack of data, we have no reasonable expectation of what it should be like, or what it shouldn’t be like.

((Wikinews)) There’s a return trip planned hopefully for 2015, with both biologists and ANDRILL geologists. Are you intending to go there yourself?

MD I would love to. But I am also happy to not go, as long as someone collects more animals on my behalf! What I want to do with the animals requires new material preserved in diverse ways, but it doesn’t require me to be there. Although I am sure that being there would enhance my understanding of the animals and the system in which they live, and would help me formulate more and better questions about the anemones, ship time is expensive, especially in Antarctica, and if there are biologists whose contribution is predicated on being there, they should have priority to be there.

((Wikinews)) These animals are shrouded in mystery. Some of the most intriguing questions are chemical; do they produce some kind of antifreeze, and is that orange glow in the ROV lights their own? Talk us through the difficulties encountered when trying to find answers with the specimens on hand.

MD The samples we have are small in terms of numbers and they are all preserved in formalin (a kind of formaldehyde solution). The formalin is great for preserving structures, but for anemones, it prevents study of DNA or of the chemistry of the body. This means we can’t look at the issue you raise with these animals. What we could do, however, was to study anatomy and figure out what it is, so that when we have samples preserved for studying e.g., the genome, transcriptome, or metabolome, or conduct tests of the fluid in the burrows or in the animals themselves, we can make precise comparisons, and figure out what these animals have or do (metabolically or chemically) that lets them live where they live.

Just knowing a whole lot about a single species isn’t very useful, even if that animal is as special as these clearly are — we need to know what about them is different and thus related to living in this strange way. The only way to get at what’s different is to make comparisons with close relatives. We can start that side of the work now, anticipating having more beasts in the future.

In terms of their glow, I suspect that it’s not theirs — although luminescence is common in anemone relatives, they don’t usually make light themselves. They do make a host of florescent proteins, and these may interact with the light of the ROV to give that gorgeous glow.

((Wikinews)) What analysis did you perform on the specimens and what equipment was used?

MD I used a dissecting scope to look at the animal’s external anatomy and overall body organization (magnification of 60X). I embedded a few of the animals in wax and then cut them into very thin slices using a microtome, mounted the slices on microscope slides, stained the slices to enhance contrast, and then looked at those slides under a compound microscope (that’s how I got the pictures of the muscles etc in the paper). I used that same compound scope to look at squashed bits of tissue to see the stinging capsules (=nematocysts).

I compared the things I saw under the ‘scopes to what had been published on other species in this group. This step seems trivial, but it is really the most important part! By comparing my observations to what my colleagues and predecessors had found, I figured out what group it belongs to, and was able to determine that within that group, it was a new species.

((Wikinews)) It was three years between recovery of specimens and final publication, why did it take so long?

MD You mean, how did we manage to make it all happen so quickly, right? 🙂 It was about two years from when Frank sent me specimens to when we got the paper out. Some of that time was just lost time — I had other projects in the queue that I needed to finish. Once we figured out what it was, we played a lot of manuscript email tag, which can be challenging and time consuming given the differing schedules that folks keep in terms of travel, field work, etc. Manuscript review and processing took about four months.

((Wikinews)) What sort of difficulties were posed by the unorthodox preservatives used, and what additional work might be possible on a specimen with intact DNA?

MD The preservation was not unorthodox — they followed best practices for anatomical preservation. Having DNA-suitable material will let us see whether there are new genes, or genes turned on in different ways and at different times that help explain how these animals burrow into hard ice and then survive in the cold. I am curious about the population structure of the “fields” of anemones — the group to which Edwardsiella andrillae belongs includes many species that reproduce asexually, and it’s possible that the fields are “clones” produced asexually rather than the result of sexual reproduction. DNA is the only way to test this.

((Wikinews)) Do you have any theories about the strategies employed to cope with the harsh environment of burrowing inside an ice shelf?

MD I think there must be some kind of antifreeze produced — the cells in contact with ice would otherwise freeze.

((Wikinews)) How has such an apparently large population of clearly unusual sea anemones, not to mention the other creatures caught on camera, gone undetected for so long?

MD I think this reflects how difficult it is to get under the ice and to collect specimens. That being said, since the paper came out, I have been pointed towards two other reports that are probably records of these species: one from Japanese scientists who looked at footage from cameras attached to seals and one from Americans who dove under ice. In both of these cases, the anemone (if that’s what they saw) was seen at a distance, and no specimens were collected. Without the animals in hand, or the capability of a ROV to get close up for pictures, it is hard to know what has been seen, and lacking a definitive ID, hard to have the finding appropriately indexed or contextualized.

((Wikinews)) Would it be fair to say this suggests there may be other undiscovered species of sea anemone that burrow into hard substrates such as ice?

MD I hope so! What fascinates me about sea anemones is that they’re able to do things that seem impossible given their seemingly limited toolkit. This finding certainly expands the realm of possible.

The American National Transportation Safety Board has announced that it will make new airline safety recommendations. This comes a result of its investigation into the Comair Flight 5191 disaster, in which a Bombardier Canadair Regional Jet (CRJ) CRJ-100ER crashed whilst attempting take-off from the wrong runway at Blue Grass Airport, Lexington, killing 49 people and leaving just one survivor. The plane was unable to take off because that runway was too short.

The NTSB has now announced that, on July 26, the date on which the NTSB is to determine the probable cause of the accident, they will issue safety recommendations regarding methods of preventing a recurrence of the disaster.

One of the recommendations will concern developing and implementing a cockpit-based system that will inform pilots when they are in the wrong location. Another will involve rescheduling the workloads of Air Traffic Controllers to ensure they receive more sleep, a request they had previously made in April.

Regarding location warning systems, the FAA has pointed out that they have been working on methods of preventing runway incursions (in which a person, ground vehicle or another aircraft is on the runway when or where it should not be), to which the National Transportation Safety Board chairman Mark Rosenker responded “The FAA is doing a great job testing these systems. The question we have is, when will you finally implement that technology?” FAA Associate Administrator Margaret Gilligan responded by saying that they were currently looking at just such a system, adding “We do have airlines that have committed to put that technology on the flight deck once it’s approved”. The system referred to involves runway signal lights and is currently being tested at Dallas-Fort Worth International Airport.

The NTSB will also look at runway and taxiway markings and the ways they can confuse pilots, as this issue has been identified as a contributing factor in the accident. Rosenker said the NTSB was “very interested” in this area. 140 airports have unclear or confusing markings in the US, but it is not certain if Blue Grass Airport is one of them. However, the Air Line Pilots Association (ALPA) made a submission to the NTSB stating that they had found that the markings at Blue Grass Airport did not match those on the charts the pilots were using. ALPA went on to recommend greater standardisation of airport runway markings.

Blue Grass Airport responded yesterday by saying that there was nothing wrong with their runway markings, with spokesman Brian Ellestad saying “We have had numerous inspections before and after (the Comair crash) and have had no issues… FAA reiterates that we meet all requirements for signage, markings, lighting, runways and taxiways.”

Belfast – An Irish construction worker accused of a record breaking £26.5 million (US$45 million) bank robbery committed in December 2004 was formally charged in a court in Belfast on Friday. Dominic McEvoy was charged with possession of a firearm and false imprisonment in connection with the case.

On December 20, 2004, McEvoy allegedly held an assistant bank manager’s family hostage while the manager and a colleague were forced to admit thieves to a branch of the Northern Bank in Belfast. The thieves then emptied the vault. Police have blamed the robbery on the IRA which has repeatedly denied any connection to the theft. Sinn Féin, a political party linked with the Provisional IRA, has protested the arrests, accusing police of targeting IRA sympathizers and supporters in their investigation.

The Northern Bank heist is one of the largest in Europe since the theft of more than US$65 million from a London bank in 1987.

The Lübeck, a Bremen class frigate of the German navy, is undergoing repairs after accidentally firing upon itself during a training mission off the British coast.

According to Korvettenkapitän Jan Ströhmer, the accident happened near Plymouth, Devon on May 2nd, where the Lübeck was taking part in an Air Defence exercise; unmanned drones towing targets for ships in the Royal Navys South Coast Exercise Areas. During the practice, the ship’s 76mm artillery gun experienced problems, possibly due to jamming. When the crew turned the gun in order to investigate the trouble, the weapon discharged. No one was hurt and the ship was not critically damaged.

The Lübeck subsequently returned to Wilhelmshaven, her home port, for repairs.

With a length of 130 meters and 3800 tonne displacement the primary role of the Lübeck is anti-submarine warfare (ASW) however she retains capabilities in anti-surface (ASuW) and anti-aircraft warfare (AAW). Her ships company numbers roughly 203.

Following a failed escape attempt on Wednesday at the detention facilities of the Subordinate Courts of Singapore, security has been increased.

At 1:45 a.m., Jamaluddin Salam, 32, and Salman Abu Samah, 28, tried to escape from the basement lock-up by requesting water. An officer opened the cell gate to fulfill the request, which is a breach of procedure; he should have merely passed water through a hole in the cell door. The prisoners took advantage of the open gate and overpowered the officer, violently punching and kicking him to the ground before heading to the gates at the lock-up’s exit, pressing a buzzer to inform the officer at the control room to unlock the gates. The officer did not check the security camera monitor to see who was at the gates before unlocking it, constituting another breach of procedure.

Following their successful exit from the lock-up, the duo used the lift just past the exit gates to reach the fourth floor of the facility, forcing open a locked door and going down a stairwell to reach the ground floor.

Within 10 minutes of the escape, the duo was spotted at the ground floor. The alarm was raised and officers were deployed to seal off all exits. Near the facility’s main entrance, Salman tripped and was quickly subdued. Jamaluddin made his way to the back entrance, but found it locked. He then doubled back to the front and dashed out of the facility. An officer tripped him with his baton about 100m outside of the facility.

The attempted escape came barely four months after terrorist-fugitive Mas Selamat Kastari fled the Whitley Road Detention Centre. Failure to observe procedures on the part of his minders was also a reason for that escape.

The two men were brought from Queenstown Remand Prison to the Subordinate Courts for bail purposes. Jamaluddin was facing six counts of robbery with hurt and drug charges, while Salman had three charges of robbery with hurt. Both cases are unrelated. Bail was set at $30,000 for Jamaluddin and $20,000 for Salman.

Police revealed yesterday that Jamaluddin and Salman were not the only inmates in the cell. It has not been revealed how many inmates were in the cell but it is known that they stayed put during the escape attempt.

In a statement, police said they have been upgrading the lock-up area since 2003, adding extra security grilles and enhancing the CCTV system.

A security audit of all lock-ups was conducted in March. The following month, a working group was set-up to look specifically into the security of the Subordinate Courts lock-up facilities.

The Criminal Investigation Department (CID) is now investigating the circumstances of the attempted escape to see if any officers were negligent.

Due to the escape attempt, security at the facility has been tightened to prevent a similar incident from happening. New security measures include an extra lock fixed onto the lock-up exit gates so that another officer will need to check who is leaving the area when it is unlocked. The elevator has also been secured and can only be activated with a key.

Jamaluddian and Salman are now likely to face a barrage of charges including vandalism, police battery and escaping from legal custody.

On the eve of the third anniversary of the June 17 raid on the central office of the National Council of Resistance of Iran and homes of dozens of Iranian political refugees and dissidents, Paris Court of Appeals in separate rulings revoked all restrictions on Mrs. Maryam Rajavi, the Iranian Resistance’s President-elect, and all those arrested on June 17, 2003. The rulings came while the investigative magistrates were insisting on continuing the restrictions.

For the past three years, Mrs. Rajavi and 16 members and supporters of the Iranian Resistance had been under judicial restrictions including the denial of the right to travel, entry to the headquarters of the National Council of Resistance of Iran in Auvers-sur-Oise, and the right to have contact with each other.

Mrs. Rajavi welcomed the verdict and said, “The case was conceived at the request of the fascist theocracy ruling Iran and was solely based on lies churned out by this regime. With the latest ruling, the time has come for this dossier to be brought to an end and all proceedings halted.”, “The shameful June 17, 2003 raid was a futile attempt to destroy Iran’s democratic opposition and aid the Iranian regime. If resistance against religious despotism for freedom is considered a crime, then I and all members and supporters of the Resistance proudly accept this crime. We are determined to establish democracy in Iran. Nothing can save the clerical regime from its inevitable fall and nothing can stop the Iranian nation from attaining freedom and democracy,” she added.

Following the court ruling, dozens of Iranian and French sympathizers of the Resistance went to Mrs. Rajavi’s residence in Auvers-sur-Oise, to congratulate her. Mayors of Auvers-sur-Oise and Cergy, in the northern Paris province of Val d’Oise also joined the celebrations.

New South Wales Police, in connection with the NSW Roads and Traffic Authority, Tow Truck Authority and Centrelink (the agency responsible for providing income support) conducted random checks on tow trucks on Thursday. The checks were carried out in Bankstown, a suburb in Sydney’s South-West.

According to police, 50 tow trucks were pulled over during the operation, coined “Operation Hook” between 8:30 a.m. AEST and 4 p.m. Of those, 26 were directed to report to a vehicle inspection facility for further investigation.

Police issued 70 infringement notices (fines) during the operation. 11 were for being unlicensed to conduct business as a tow truck driver or business, and 13 for having incorrectly secured loads. 17 vehicles were issued defect notices as part of the operation.

Tow truck operators (business owners) are required to make a payment of AUD$770 per year to the NSW government, while drivers are charged $152 per year for their licence. An additional charge for tow truck number plates of $292 per year also applies.

The maximum penalty for operators not being licensed correctly is $11,000 or 12 months imprisonment, drivers without the correct licence can be fined $5,500 or sentenced to 6 months.

Wednesday at the American Institute of Physics Industrial Physics Forum meeting in San Francisco, a group of researchers proposed new research into an old way, invented by Nikola Tesla, to transfer power wirelessly. Marin Soljacic and his MIT colleagues revived an idea which involves a source that creates a short range oscillating field. Nearby circuits that resonate at the frequency of the source absorb some of the energy. The system would operate in much the same way as the coils inside a transformer, except that the researchers believe they can develop sources that transfer energy over much longer distances than is typical in transformers. Technology based on this proposal could mean wireless gadgets such as cell phones and iPods never have to be plugged into a wall outlet. The researchers also propose that it could power micro-robots or other machines that are too small to carry their own batteries. Eventually it might enable electric transportation such as buses to recharge wirelessly through power sources near the roadway. One potential problem with the system could be its inefficiency. Soljacic’s calculations show that it is at best 60% efficient.
