Effects of a simulated Martian UV flux on the cyanobacterium, Chroococcidiopsis sp. 029

first_imgDried monolayers of Chroococcidiopsis sp. 029, a desiccation-tolerant, endolithic cyanobacterium, were exposed to a simulated martian-surface UV and visible light flux, which may also approximate to the worst-case scenario for the Archean Earth. After 5 min, there was a 99% loss of cell viability, and there were no survivors after 30 min. However, this survival was approximately 10 times higher than that previously reported for Bacillus subtilis. We show that under 1 mm of rock, Chroococcidiopsis sp. could survive (and potentially grow) under the high martian UV flux if water and nutrient requirements for growth were met. In isolated cells, phycobilisomes and esterases remained intact hours after viability was lost. Esterase activity was reduced by 99% after a 1-h exposure, while 99% loss of autofluorescence required a 4-h exposure. However, cell morphology was not changed, and DNA was still detectable by 4′,6-diamidino-2-phenylindole staining after an 8-h exposure (equivalent to approximately 1 day on Mars at the equator). Under 1 mm of simulant martian soil or gneiss, the effect of UV radiation could not be detected on esterase activity or autofluorescence after 4 h. These results show that under the intense martian UV flux the morphological signatures of life can persist even after viability, enzymatic activity, and pigmentation have been destroyed. Finally, the global dispersal of viable, isolated cells of even this desiccation-tolerant, ionizing-radiation-resistant microorganism on Mars is unlikely as they are killed quickly by unattenuated UV radiation when in a desiccated state. These findings have implications for the survival of diverse microbial contaminants dispersed during the course of human exploratory class missions on the surface of Mars.last_img read more

50-up for Bok coach Jake White

first_img28 September 2007When South Africa takes to the field in their final Rugby World Cup Pool A match against the United States in Montpellier on Sunday, Jake White will reach the 50-match milestone as Springbok coach, the first man to achieve the feat.A victory over the Americans would lift White’s winning percentage to 64 percent, third among coaches since South Africa rejoined world rugby in 1992. Difficult startWhen the former Jeppe schoolmaster took over the reins of the Springbok side, it was at a low point in the team’s fortunes; they had exited the 2003 World Cup at the quarterfinals’ stage, beaten 29-9 by New Zealand, and the Boks’ image was under the spotlight after the controversial Kamp Staaldraad became public knowledge.White, though, was eager to take on the challenge of one of the toughest coaching jobs in South Africa, assuming a position that had claimed a fair number of victims, as coaches left the post before their contracts were up.One of his first messages to the players was that they were going to win the World Cup in 2007. Now, four years on, and after nearly having lost his job at the end of 2006, White is in charge of a confident team, one that many experts believe is the only side capable of challenging New Zealand for World Cup glory.Outstanding performancesWith the quarterfinals approaching, two matches stand out as outstanding performances at the 2007 World Cup: the All Blacks’ 76-14 humbling of Italy, and, arguably more impressive, the Springboks’ 36-0 whitewash of defending champions England.The Kiwis, in their win, showed a fantastic cutting edge, while South Africa, in their victory, exhibited powerful, controlled, and focused form.The lightly-regarded Americans, winless so far, and facing what is close to a full strength Bok line-up, aren’t expected to cause White’s men many problems. The coach has his team in the exact position he wants them to be in, and a win will likely mean a match against Wales in the last eight.PlayoffsShould South Africa beat the Welsh – and they have previously lost only once to Wales – they will tackle either France or Argentina in the semi-finals.The French have provided the Springboks with some tough matches in the past, but the Pumas have never beaten them, although the South American Jaguars, comprised most of Argentinian players, once beat the Boks 21-12 in Bloemfontein in 1982, with the legendary Hugo Porta scoring all his team’s points.Sunday’s match will be only the third between South Africa and the USA. In the two previous encounters, SA won 38-7 in 1981 and 43-20 in 2001, both times on American soil.Team selectionCoach White and his fellow selectors have opted for a lineup that closely mirrors the one that overpowered England.There is one change in the backline, with Akona Ndungane getting his first run of the tournament after overcoming a chest injury. He replaces JP Pietersen, who moves to the bench.Up front, Schalk Burger returns to action, having served his two-match ban for a dangerous tackle against Samoa. He, however, won’t be in action in his regular position on the flank. Instead, he will pack down at number-eight.Juan Smith, his regular partner at flank, will join forces with the industrious Wikus van Heerden.Albert van den BergIn a somewhat surprising move, White has opted to break up the Blue Bulls’ dominating second row, selecting Victor Matfield, but partnering him with Albert van den Berg and not Bakkies Botha.Van den Berg, who made his Springbok debut way back in 1999 against New Zealand, will win his 50th Springbok cap.Os du Randt, when he takes on the Eagles, will have played against more countries than any other Springbok; it will be the 18th nation he faces, breaking a tie with Joost van der Westhuizen.First-choice teamIn the Boks’ last outing, a 30-25 victory over Tonga, it became clear that there is a distinct difference between the first-choice lineup and the second-choice team, especially when one remembers the struggles of a similar selection against Irish side Connacht, a match that SA won only 18-0.The bench, boasting an incredible 311 caps, helped quell the Tongan bid to upset the hierarchy of world rugby, and all the players who served as substitutes in that match will start on Sunday. In total, there are 586 caps among the starters and 185 among the reserves.Starting FifteenPercy Montgomery, Akona Ndungane, Jaque Fourie, Francois Steyn, Bryan Habana, Butch James Fourie du Preez, Schalk Burger, Juan Smith, Wikus van Heerden, Victor Matfield, Albert van den Berg, BJ Botha, John Smit (c), and Os du RandtBenchBismarck du Plessis, CJ van der Linde, Bakkies Botha, Bob Skinstad, Ruan Pienaar, Andre Pretorius, and JP Pietersen Want to use this article in your publication or on your website?See: Using SAinfo materiallast_img read more

first_imgAC Milan coach Giampaolo admits ‘much to improve’ after beating Veronaby Carlos Volcanoa month agoSend to a friendShare the loveAC Milan coach Marco Giampaolo refused to get carried away after their 1-0 defeat of Hellas Verona.Mariusz Stepinski saw red in the first-half, but Milan only edged the game thanks to a Krzysztof Piatek penalty.“The team is working well, is finding its balance and I know there are some strengths and weaknesses, but I work to improve the individuals and the teams,” Giampaolo told Sky Sport Italia.“Everyone has strengths and weaknesses, there is no perfect side. I like the effort and passion we put into the game, then errors can happen.“The team played well in the second half, with the right approach and precision. A team that defends with 10 men in their final third are difficult to break down. Verona played their honest defensive game and we were constantly pushing forward. We didn’t do it perfectly and of course there is plenty to work on and improve, but the victory helps us to work.” About the authorCarlos VolcanoShare the loveHave your saylast_img read more

Tourists rescued from Karnatakas floodhit Hampi heritage site

first_imgBengaluru: As many as 365 tourists, including 100 from overseas, were rescued from the world famous Hampi heritage site in Karnataka, as heavy rains and flash floods stranded them over the last 2-3 days, an official said on Tuesday. “The Indian Air Force (IAF) crew airlifted the marooned tourists in MI-17 helicopter and the Advanced Light Helicopter (ALH) Dhruv, in batches from a guest house near the Virupapura gadde (island) temple at the Hampi heritage site to the Vijayanagar airport between Hospet and Ballari towns in the state’s northwest region over the last two days,” the official told IANS here. Also Read – Uddhav bats for ‘Sena CM’ Located on the south bank of the Tunga-Bhadra joint rivers, the Unesco recognised heritage site, dotted with ruins and monuments from the 14th century Vijayanagara empire, including the 7th century Virupaksha temple, was inundated after the authorities released excess water from the nearby dam. Hampi in the rich-mining district of Ballari is about 340 km northwest of Bengaluru. “As the 20 km road connectivity to the heritage site from Hospet town was flooded and damaged, the tourists had to be airlifted in turns as they were stranded in a state-run guest house near the temple on an island,” said the official. Also Read – Farooq demands unconditional release of all detainees in J&K With the southwest monsoon being active since August 1, heavy rains in the catchment areas of the Tunga and Bhadra rivers in the state’s Malnad region filled the reservoir to the brim where the two rivers join near Hospet. “As 2.5-lakh cusecs of water were released from the TB dam since Saturday, the ancient monuments, temple complexes and the market places (bazars) were flooded when the overflowing water breached the banks and entered the ruins,” recalled the official. The choppers were also used to airlift four National Disaster Response Force (NDRF) personnel to safety as they were stuck on the rocks that were submerged by the swirling waters. Other historical places at Hampi, including Purndara mantapa (canopy) and Chola mantapa were submerged while Kampli fort and Anjaneyaswamy temple were flooded due to the TB river overflowing. Hundreds of tourists and pilgrims were also rescued by the state and national disaster response forces from flood-hit Pattadakal in the neighbouring Bagalkot district, which has an another Unesco recognised world heritage site for its 7th-8th century Hindu and Jain temples and monuments. State Tourism Secretary, T.K. Sunil Kumar, however, clarified that there was no damage to the monuments and temples at both the heritage sites due to inundation by the rain water or flooding due to overflowing of the river water. “Measures have been taken to clear the water from the heritage sites by pumping it from the complexes and making ways for reversing the flow back to the river or diverting it in open areas or fields,” Kumar told reporters here. Pattadakal, about 440 km northwest of the state capital (Bengaluru) is one of the prime tourist and religious destinations in the southern state. “Pattadakal is a harmonious blend of architectural forms from the northern and southern India and an illustration of eclectic art. The Hindu temples are dedicated to Shiva, with elements of Vaishnavism and Shaktism fused,” said Unesco for declaring it a world heritage site.last_img read more

Crucial detail left out of Ontarios new child welfare legislation

first_imgKanina Sue Turtle, left, Courtney Scott and Amy Owen all died within six months of each other while living in Ontario group homes between October 2016 and April 2017. They were just a few of the Indigenous children placed in care at the time.Kenneth JacksonAPTN NewsWhen the Ontario government passed new legislation on child welfare last year it required that the province’s 49 children’s aid societies start collecting race-based data for the first time.That collection was to begin Feb. 5 and as APTN News reported last week not a single society has submitted any statistics to the ministry of Children and Youth Services.Turns out there are a number of reasons for this and perhaps the most important is the province never required societies to actually submit the data.“Despite the policy directive and requirement to collect the data, which Children’s Aid Societies are fulfilling, there is no requirement to report data to the Ministry,” said Sean McGrady, a spokesperson for the Ontario Association of Children’s Aid Societies in an email to APTN Friday.McGrady did say the societies are collecting the data as required under the legislation.Related: Three First Nations girls died in Ontario group homes in last 6 monthsThis new data collection was touted by the previous Liberal government, in fact the former minister, Michael Coteau, came on APTN’s Nation to Nation in February and said it was the “most comprehensive piece of legislation” for child protection.“We know it will allow us to make better decisions,” Coteau said of the data collection.But he failed to mention there was no requirement to submit it.He also said a network, that was first developed several years ago, would allow societies to submit the data.Turns out that network, known as the Child Protection Information Network (CPIN), lacks certain functions and not all societies are using it all these years later according to McGrady.“CPIN does not currently have the ability to produce a report on the race-based data being collected by Children’s Aid Societies. We are eager for the Ministry to create this reporting function,” said McGrady.“Children’s Aid Societies want to begin analyzing the data to enhance their response and services to diverse communities.”While McGrady answered questions almost immediately, APTN had a difficult time getting responses from the ministry.In fact, it’s common to wait days for an answer to a single question.On Friday, before McGrady had contacted APTN, the ministry responded to previous questions pertaining to why the ministry wasn’t requiring the societies to submit the data. (At that point APTN didn’t know there was no requirement).“The ministry expects to review the initial data collected in early 2019,” said spokesperson Trell Huether in an email.But the ministry also said of the 49 societies just 30 were using the network.APTN asked why that was the case.“By 2020, all non-Indigenous societies are expected to be on the Child Protection Information Network,” said Huether. “Societies not yet on the Child Protection Information Network are to start collecting this data once they “go live” on the network.”See also: Ojibway teen sleeping in Ottawa mall stairwell after aging out of group homeThe remaining societies are Indigenous, that are mandated by the province.“The ministry is in discussions with Indigenous partners to develop a plan with respect to the Child Protection Information Network,” said Huether.APTN followed up asking why, if the legislation requires data collection, why wasn’t it mandatory for the societies to submit the data.There hasn’t been an response, other than the ministry is working on an answer.Meanwhile, McGrady said Wednesday the societies are working with the province.“Although the timing for the first report to the Ministry is under discussion, the plan is for reporting to the Ministry to be done on a quarterly basis in the future,” he said.In depth: Child welfare agency suspected First Nations girls were planning suicidesOntario has never tracked the kids in child protective services by race and recent statistics put the total number of kids in care at about 14,500 by the Ontario Association of Children’s Aid Societies.But that number in tallied from 41 of the societies. It’s not a complete picture of the total amount, regardless of race.So where is the starting point? How do you fund culturally appropriate programs for Indigenous kids if you don’t know where they are?Those are questions the office of the Ontario Child Advocate has been asking for many years.“Any of these regulations for this new legislation and any of the policies following through for children and youth in the province have to be done based on knowing who the kids are, knowing where the kids are, knowing what conditions those kids are in,” Trevor McAlmont, director of advocacy services with the Child Advocate, said last week.The Child Advocate is an independent office that is directed to look out for the best interests of children in care.“So if we don’t know that and we don’t start there then it’s problematic,” McAlmont said.As for there being no requirement to submit the data, a spokesperson for the Child Advocate said they were unaware.APTN continues to wait for the ministry to respond to additional [email protected]last_img read more
