Monday, March 19, 2012 Hawker, Canberra — Coming off a national championship win for the Australian Capital Territory (ACT) men’s open team in mid-February, Australia men’s national softball team representatives Nick Norton and Adam Folkard are getting ready for more softball later this year, including the Australian club championships to be held in Brisbane in June.

Folkard and Norton have both won the World Championships and have each won a total of ten national championships with the ACT side. They are both named to the current men’s national team, which has roughly thirty players, and believe they are likely to survive the December cut down to eighteen players who will represent Australia at next year’s World Championship in Auckland, New Zealand.

The World Championship is one of the two most prestigious available to male softball players. The other is the International Softball Congress, an event Folkard and Norton have both competed at.

As national team representatives, there are a lot of expectations for them. In Australia, there is almost no financial support for the men’s game so they must cover most of their own costs, including travel to and from international competitions. According to Folkard’s father, these costs can be prohibitive. In one year, when Folkard was a representative on the men’s U18, U23 and Open team, it cost A$15,000 for travel and other expenses just for Folkard. When costs for bringing family members such as Folkard’s sisters to major international tournaments, the costs were even higher. Folkard, his father and Norton all joked this cost his father an investment property to allow Folkard to continue to compete at the highest level. Both Folkard and Norton currently work as tradesmen to support softball playing.

Beyond money, the national team requires players to be actively involved in wider softball community. Players must represent a club at the club championships in Brisbane if they want to retain a spot in the squad. Folkard plays for a Western Australian club and Norton plays for a Sydney based club, driving down from Canberra to play every Sunday during the season.

Folkard and Norton have both played softball at the highest level in the United States, where the men’s game is not yet fully professionalized but still presents more opportunities for players than are available at home. For several years, Folkard has gone to the United States for three-month stints, playing for teams in Chicago, Pennsylvania, and New York. One side he played was sponsored by Ernst and Young. Folkard currently plays for a Canadian side and has been trying to convince Norton, whom he has grown up playing softball with, to join him like Norton has done one previous season. According to Folkard, playing with a North American club has certain advantages. The clubs pay for his travel to and from Australia, and pay for Championship rings. When asked how North American clubs sign Australian players, he said they follow men’s softball in Australia and call up players to offer contracts. Australian men’s players gain additional exposure to potential clubs when they compete, with some sides approaching them during the North American season and seeking to contract them for the following season.

Both men would love the opportunity to play softball in the Olympics, but believe such an opportunity is unlikely. According to them, softball at the Olympics is a women’s game intrinsically linked to men’s baseball, and men’s softball is unlikely to ever be considered on the programme as a result.

Folkard and Norton both play for the same club in the ACT territory club competition. Their team has secured a grand final berth for the match in ten days. They are waiting to find out who they will play against based on a match this weekend. Both have previously won this competition.

Commander Leroy Chiao and Flight Engineer Salizhan Sharipov have just completed their mission’s first space walk aboard the International Space Station. The mission lasted 5 hours, 28 minutes, ending at 1311 UTC. The two astronauts, working in Russian space suits, performed a variety of tasks. Chiao and Sharipov installed a work platform, called the Universal Work Platform, along with its base and associated wiring. They also installed a commercial robotics experiment and a biological experiment on the exterior of the Zvezda Service Module. In addition, they checked vents on systems that help control the Station’s atmosphere and relocated a Japanese physical science experiment.

Residue accumulation around the vents of the Elektron oxygen generator was noted and photographed by Sharipov. Technicians on the ground will analyze the information to determine if this residue has been contributing to the problematic operation of the Elektron.

During this spacewalk, the station again encountered the mysterious forces that have been saturating the Control Moment Gyros during previous spacewalks. Russian thrusters were activated to counter this force.

The walk marks Chiao’s fifth for 31 hours, 34 minutes, accumulated time and Shapirov’s first.

This was the 57th space walk conducted at the Station and the 32nd to be based out of the orbital outpost. Expedition 10 is scheduled to conduct its second spacewalk in March.

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.

Five civilian contractors have been injured after an explosion and fire onboard the Ticonderoga-class guided missile cruiser USS Leyte Gulf at 9:25 a.m. today.

A large explosion erupted from the ship’s berthing area where welding work was being conducted during a stop in Norfolk, Virginia. A fire broke out two decks below main deck, but was quickly extinguished. The injured were taken to Norfolk General Hospital for treatment to injuries not believed to be life-threatening, according to John Kowalczyk, a spokesman for BAE Systems Ship Repair, who were conducting the work.

He added that the fire appeared to be an isolated incident. The ship has been laid up for repairs and modernizing since May.

In findings published Sunday in Environmental International, a team from Britain’s University of Exeter reports that surfers and bodyboarders are roughly three times as likely to house antibiotic-resistant Escherichia coli and other bacteria that could easily become resistant, than other people who recreate in the coastal waters of the United Kingdom.

The epidemiological study was nicknamed the “Beach Bum Survey”. The project was performed on 143 regular surfers, body surfers and bodyboarders from around the United Kingdom. Each surfgoing participant was asked to recruit a non-surfing friend of the same sex and approximate age and who lived in the same part of the country to serve as a control, which resulted in a control group of 130.

All participants mailed in rectal swabs, and the researchers cultured the E. coli from those samples with a common antibiotic called cefotaxime. The antibiotic failed to kill the bacteria in about 9% (13 out of 143) of surfer and bodyboarder samples and 3% of the samples from the control group (4 out of 130). A deeper look into the genomes of the specific strains of bacteria found in the study volunteers showed that bacteria from surfers were four times as likely to possess genes that can be transferred from one bacterial strain to another, which can help antibiotic-susceptible bacteria become resistant. The study also involved examination of water samples from the coasts of England and Wales to estimate the risk of surfers and other beachgoers ingesting E. coli.

E. coli is a regular resident in the guts of humans and other animals. Most strains are harmless but others can cause serious disease. Like other bacteria, E. coli can undergo horizontal gene transfer, swapping genes from one bacterium to another. This can give the altered strain the ability to cause disease, survive in the presence of antibiotics or both.

Although the researchers expressed concern surfers might spread dangerous bacteria, Dr. Will Gaze, the University of Exeter Medical School professional who supervised the project, urged people not to avoid the beach: “We are not seeking to discourage people from spending time in the sea, an activity which has a lot of benefits in terms of exercise, well-being and connecting with nature”, he said. “It is important that people understand the risks involved so that they can make informed decisions about their bathing and sporting habits. We now hope that our results will help policy-makers, beach managers, and water companies to make evidence-based decisions to improve water quality even further for the benefit of public health.”

David Smith, science and policy officer of Surfers Against Sewage, which helped organise the volunteers, agreed the study was not meant to discourage surfing: “Water quality in the UK has improved vastly in the past 30 years and is some of the cleanest in Europe. Recognising coastal waters as a pathway for antibiotic resistance can allow policy makers to make changes to protect water users and the wider public from the threat of antibiotic resistance.”

One of the principal findings of this work was that existing methods may have been underestimating the prevalence of these bacteria in seawater. Previous studies have shown that even designated swimming beaches can be affected by runoff from farms or even sewage, and surfers swallow roughly ten times as much seawater as swimmers. Professor Colin Gardner of the charity Antibiotic Research UK says, these forms of runoff can have even higher concentrations of antibiotics than patients undergoing antibiotic treatment. “Research into new medicines to replace our archaic antibiotics has stagnated and unless new treatments are found, this could be potentially devastating for human health”, he warns.

The World Health Organization has reported that because so many kinds of bacteria are gaining resistance to common medicines, conditions such as pneumonia and gonnorhea may become more difficult to treat and have higher rates of sickness and death. Doctors often prescribe preventative antibiotics to patients undergoing surgery or radiation therapy, and this may also be impacted. Professor Sally Davies, England’s chief medical officer, has described a “post-antibiotic apocalypse” scenario

The European Regional Development Fund and Natural Environment Research Council provided funding for the study.

A major security hole was discovered in the pseudo-random number generator (PRNG) of the Debian version of OpenSSL. OpenSSL is one of the most used cryptographic software, that allows the creation of secure network connections with the protocols called SSL and TLS. It is included in many popular computer programs, like the Mozilla Firefox web browser and the Apache web server. Debian is one of the most used GNU/Linux distributions, on which are based other distributions, like Ubuntu and Knoppix. The problem affects all the Debian-based distributions that were used to create cryptographic keys since the September 17, 2006. The bug was discovered by Luciano Bello, an argentine Debian package maintainer, and was announced on May 13, 2008.

This vulnerability was caused by the removal of two lines of code from the original version of the OpenSSL library. These lines were used to gather some entropy data by the library, needed to seed the PRNG used to create private keys, on which the secure connections are based. Without this entropy, the only dynamic data used was the PID of the software. Under Linux the PID can be a number between 1 and 32,768, that is a too small range of values if used to seed the PRNG and will cause the generation of predictable numbers. Therefore any key generated can be predictable, with only 32,767 possible keys for a given architecture and key length, and the secrecy of the network connections created with those keys is fully compromised.

These lines were removed as “suggested” by two audit tools (Valgrind and Purify) used to find vulnerabilities in the software distributed by Debian. These tools warned the Debian maintainers that some data was used before its initialization, that normally can lead to a security bug, but this time it was not the case, as the OpenSSL developers wrote on March 13, 2003. Anyway this change was erroneously applied on September 17, 2006, when the OpenSSL Debian version 0.9.8c-1 was released to the public.

Even though the Debian maintainer responsible for this software released a patch to fix this bug on May 8, 2008, the impact may be severe. In fact OpenSSL is commonly used in software to protect the passwords, to offer privacy and security. Any private key created with this version of OpenSSL is weak and must be replaced, included the session keys that are created and used only temporary. This means that any data encrypted with these keys can be decrypted without a big deal, even if these keys are used (but not created) with a version of the library not affected, like the ones included in other operating systems.

For example any web server running under any operating system may use a weak key created on a vulnerable Debian-based system. Any encrypted connection (HTTPS) to this web server established by any browser can be decrypted. This may be a serious problem for sites that requires a secure connection, like banks or private web sites. Also, if some encrypted connection was recorded in the past, it can be decrypted in the same way.

Another serious problem is for the network security software, like OpenSSH and OpenVPN, that are used to encrypt the traffic to protect passwords and grant the access to an administrative console or a private network protected by firewalls. This may allows hackers to gain unwanted access to private computers, networks or data traveled over the network, even if a not affected version of OpenSSL was used.

The same behavior can be applied to any software or protocol that use SSL, like POP3S, SSMTP, FTPS, if used with a weak key. This is the case of Tor, software used to offer strong anonymity on the TCP/IP, where about 300 of 1,500-2,000 nodes used a weak key. With 15-20% of weak Tor nodes, there is a probability of 0.34-0.8% circa to build a circuit that has all tree nodes weak, resulting in a full loss of anonymity. Also the case of only one weak node begin used may facilitate some types of attack to the anonymity. The Tor hidden services, a sort of anonymous public servers, are affected too. However the issue was speedly addressed on May 14, 2008.

The same problem also interested anonymous remailers like Mixmaster and Mixminion, that use OpenSSL to create the remailer keys for the servers and the nym keys for the clients. Although currently there is no official announcement, at least two remailer changed their keys because were weak.

The U.S Consumer Product Safety Commission has recalled more products over the last few days, though not all because of excessive lead.

While American toy companies have been rocked in the last few months by numerous unsafe Chinese-made products, mostly due to excessive amounts of lead in paint, a few of the latest recalls were actually due to design flaws.

Also recently recalled are sunglasses and toy cars from the Dollar General chain of price-point retailers.

The United Kingdom’s (UK) largest technology company, ARM Holdings, confirmed on Monday morning that it had accepted an offer from the Japanese company, SoftBank.

ARM designs microchips used in many devices, including smart phones made by Apple and Samsung. It is expected to invest in the so-called Internet of Things, where many everyday items are expected to be connected to the internet into the future.

The deal, worth £24 billion (US$32 billion), is now expected to be presented to shareholders. The amount offered per share is 43% above the value at the close of trading on Friday. Shares rose by 45% on Monday morning in response to the announcement. Three-quarters of shareholders will need to approve the deal for it to go ahead.

ARM has said its headquarters will remain in Cambridge. Simon Segars, ARM’s Chief Executive, also said a pledge by SoftBank to double ARM’s workforce on the UK would be legally binding.

Philip Hammond, the UK Chancellor, said it would be the biggest investment into the UK from Asia, as well as showing that “Britain remains one of the most attractive destinations globally for investors to create jobs and wealth”. Theresa May, the UK Prime Minister, had recently questioned the benefit to the nation of such takeovers, but has said this one shows the UK can remain successful outside the European Union.
