first_imgFaunal assemblages at hydrothermal vents associated with island-arc volcanism are less well known than those at vents on mid-ocean ridges and back-arc spreading centres. This study characterizes chemosynthetic biotopes at active hydrothermal vents discovered at the Kemp Caldera in the South Sandwich Arc. The caldera hosts sulfur and anhydrite vent chimneys in 1375–1487 m depth, which emit sulfide-rich fluids with temperatures up to 212°C, and the microbial community of water samples in the buoyant plume rising from the vents was dominated by sulfur-oxidizing Gammaproteobacteria. A total of 12 macro- and megafaunal taxa depending on hydrothermal activity were collected in these biotopes, of which seven species were known from the East Scotia Ridge (ESR) vents and three species from vents outside the Southern Ocean. Faunal assemblages were dominated by large vesicomyid clams, actinostolid anemones, Sericosura sea spiders and lepetodrilid and cocculinid limpets, but several taxa abundant at nearby ESR hydrothermal vents were rare such as the stalked barnacle Neolepas scotiaensis. Multivariate analysis of fauna at Kemp Caldera and vents in neighbouring areas indicated that the Kemp Caldera is most similar to vent fields in the previously established Southern Ocean vent biogeographic province, showing that the species composition at island-arc hydrothermal vents can be distinct from nearby seafloor-spreading systems. δ13C and δ15N isotope values of megafaunal species analysed from the Kemp Caldera were similar to those of the same or related species at other vent fields, but none of the fauna sampled at Kemp Caldera had δ13C values, indicating nutritional dependence on Epsilonproteobacteria, unlike fauna at other island-arc hydrothermal vents.last_img read more

Billy Hart. “RCOH is one of the world’s most complex industrial jobs, and deckplate by deckplate, we’re taking back the ship so our Sailors can live, train and operate aboard to return TR to the fleet.”During the first phase of CMA, supplies such as mattresses, new damage control equipment, computers and communication equipment will be moved aboard. The duty section will also be able to use berthing areas on the ship and various departments will begin moving and working aboard the ship as well.“I think we are doing great as far as getting spaces ready,” said Cmdr. Chad Hixson, strike operations officer and CMA coordinator. “Spaces that are groomed and ready to be lived in look great.”The second phase, ‘eat aboard’, scheduled for June, will feature the ship’s galley opening to serve meals to the crew onboard the ship.CMA is scheduled to end in September after the third phase, ‘work aboard’, where all departments will be expected to be operating on the ship, is complete.“CMA is about us taking back our house and getting back onto our turf,” said Hixson. “It’s about ownership. This is our home. This is what it’s all about.”[mappress]Naval Today Staff , May 23, 2012 Training & Education View post tag: USS View post tag: process Share this article View post tag: Naval View post tag: Theodore View post tag: CMAlast_img read more

first_imgEvery year, a “dead zone” the size of Massachusetts sprawls across the Gulf of Mexico. The Mississippi River, which travels through the nation’s farm belt, sweeps excess fertilizer and dumps the chemicals into the Gulf, where they feed rampant algae, deplete oxygen, and kill marine life.Across the U.S., smaller versions of similar dead zones infect lakes, ponds, and rivers. In years with higher rainfall — like 2018 — Massachusetts’ Charles River collects enough pollutants from surrounding city streets, parking lots, and landscaped campuses to cause the water quality to drop. Unchecked algae growth, often the result of excess fertilizer, can damage marine, human, and even pet health: This year, several dogs died after swimming in water choked with toxic blue-green algae.Now, Harvard scientists are teaming up with sustainability officers and landscaping experts to test a new fertilizer that won’t wash into water supplies. Using the Cambridge campus as a living laboratory, the team, which includes Dilek Dogutan, Quentin Gilly, and Paul Smith, plans to pilot the sustainable biofertilizer on Harvard’s grounds, starting this winter. Developed in the lab of Daniel Nocera, the Patterson Rockwood Professor of Energy, the living biofertilizer, which operates with just sunlight, air, and water, remains with the plants, produces bigger and healthier specimens, and is carbon-negative, absorbing carbon dioxide from the air and sequestering the dangerous greenhouse gas in the soil.The pioneering effort began last spring, when Dogutan, a principal research scientist in the Nocera group, got an email from the President’s Administrative Innovation Fund (PAIF). In it she saw an opportunity to apply her lab’s research to the campus right outside her window. In previous experiments, the team had used the biofertilizer to grow radishes more than three times the size of controls grown without fertilizer. But the experiments took place in the stable conditions of a greenhouse.“We wanted to take the research out of the controlled environment, to see the effect of soil acidity, air, temperature, humidity, everything,” Dogutan said. To do that, she needed help. Through PAIF, she formed a collaborative team with Gilly, the manager of laboratory sustainability and energy of the FAS Green Program in Harvard’s Office for Sustainability, and Smith, the associate manager of landscape services.,Gilly said the University is in the process of transitioning to all organic fertilizers, with a goal of 75 percent organic landscaping by 2020. But these fertilizers still end up in the water; the Nocera lab’s biofertilizer does not.Invented in 2018, the biofriendly fertilizer relies on an engineered cyanobacteria called Xanthobacter autotrophicus. The invention incorporates years of research, going back to Nocera’s artificial leaf technology, which splits water to make hydrogen and oxygen, performing photosynthesis better than any leaf.The new treatment uses the hydrogen from water splitting and combines it with nitrogen in air to produce ammonia, which plants can absorb into their roots. Since inorganic and organic fertilizers often give plants more nitrogen and phosphorous than they can use at one time, the excess gets washed away. But the biofertilizer stays safe within the plants’ roots, stored for future use.The innovation has another ecofriendly trick: The bacteria absorb carbon dioxide from the air. “Using the new biofertilizer methods across the U.S., we could remove significant amounts of CO2 per year by sequestering the carbon in the soil,” Dogutan said.With the help of the Office of Technology Development, Nocera, Pamela Silver, the Elliot T. and Onie H. Adams Professor of Biochemistry and Systems Biology at Harvard Medical School, and Xiaowen Feng, a former member of her lab, founded a company called Kula Bio, which arranged a first field test off campus. Marching toward commercialization, Kula Bio hopes its product will replace all synthetic nitrogen fertilizers — those responsible for high levels of runoff and CO2 emissions — with a low-cost organic biofertilizer. “We have to do something because, really, we’re destroying the world. Coming to work every day is great, but what is our higher purpose? It’s not just sending those emails.” — Dilek Dogutan Related Unsafe levels of toxic chemicals found in drinking water of 33 states It takes a community to make compost Arnold Arboretum partners with local businesses to turn trash to dark-brown gold On campus, with funding from the PAIF, Dogutan and her team will perform large-scale tests of the fertilizer from winter 2020 through the following fall. But, with an earlier grant from the Campus Sustainability Innovation Fund, she has already planted two small test plots. In one, she and Daniel Loh, a Ph.D. student in the Department of Chemistry at the Graduate School of Arts and Sciences and a member of the Nocera Lab, cleared two parking spot-size gardens with a two-foot grass buffer between. Loh planted radishes, turnips, and spinach in each. Then, every week, he fertilized one with 100 milliliters of the engineered cyanobacteria mixed with waterand sprayed it over the plants. The other plot got just as much water, without the bacteria.From April to August, Loh and undergraduate researchers Ellen Deng and Lauren Church monitored the plants and collected data. Loh’s measurements showed that not only did the biofertilizer help his plants grow larger than those in the unfertilized plot, the bacteria did not leech into the surrounding plants. “Nutrients are taken up by plants before they can diffuse large distances,” he said.With the data collection complete, Loh ate his research: He harvested and shared his vegetables with the entire Nocera group.,Next, Deng wants to plant pink roses, her favorite flower. Gilly hopes to use the biofertilizer in campus rain gardens, which are designed by undergraduate students to better absorb rain water and prevent pooling. “Every year, the new first-years who come in are more and more passionate about environmental causes,” Gilly said. “They’re an ever-growing force of sustainability.”Over the next year, Dogutan and Harvard’s landscaping services will replace organic fertilizer with the biofertilizer on areas across Harvard’s Cambridge campus — the size of the plots only depends on how much of the new treatment they can get from Kula Bio, which is donating it. The more, the better, Dogutan said. More data will help her and the team hone their product for widescale use.“This is still very new research,” Dogutan said. “We are still trying to figure out the details: the loading, the sequence, maybe we need to design the bacteria in a different way.” Once they do, they hope to encourage all Harvard campuses to consider switching to the biofertilizer as a way to improve the University’s commitment to sustainability and eventually to win wider acceptance and perhaps end “dead zones.”“We have to do something because, really, we’re destroying the world,” Dogutan said. “Coming to work every day is great, but what is our higher purpose? It’s not just sending those emails. The higher purpose, at least for me, is giving back to the Harvard community the best way that I can.” High levels of fluorinated compounds have been linked to cancer, hormone disruptionlast_img read more

first_imgThe US, he discovered, operated 40,000 commercial flights a day, compared to 420 in India. He did a quick back-of-the envelope calculation: if 5% of the roughly 30 million Indians who travelled by train and bus began flying, that would translate into an eye-popping 530 million air travellers a year. “Even if this number looked huge, it did not mean 530 million different people travelling but 200 million middle-class people travelling two and half times a year, which was not an unimaginable prospect over the next 30 years,” he explains. – Advertisement –last_img read more

first_imgEmpty classrooms, shuttered restaurants and hospitals bursting with patients. That was the scene in Mexico City in 2009 when a new strain of flu swept across much of the country and spread around the world.Just 11 years after the swine flu outbreak, which infected more than 60 million people in the US alone and took as many as half a million lives worldwide, the new coronavirus is threatening to spark another global epidemic.Health officials are trying to contain the virus that causes Covid-19, a pneumonia-like illness that can be severe in a minority of patients and spread from others who look healthy. Now, researchers and disease trackers are teetering on the brink of calling it a pandemic, a crisis that will likely affect the entire world. ‘Getting worse’The distinction may not be necessary, according to Anthony Fauci, director of the US National Institute of Allergy and Infectious Diseases.“The situation is getting worse; all you have to do is look at the numbers,” he said. “If the trend continues the way we’re seeing now, we’re going to have a problem. Whatever you call it, it’s not good.”But the eight-letter word resonates with state and local health departments, hospitals, clinics and nursing homes, Schaffner said. Many of them have pandemic plans, developed and refined after earlier outbreaks, that will need to be dusted off, reviewed and implemented.The reasons for calling this outbreak a pandemic now are many, according to Tom Frieden, a former CDC director and New York City health commissioner. Researchers can’t trace all the links between outbreaks in different nations; the spread in hospitals and families shows the virus is quite transmissible; some countries that haven’t reported cases probably have them; and simple calculations suggest the tallies of travelers with the disease are probably just a fraction of the real number.“A pandemic is inevitable and we should call it what it is,” Frieden said. “What’s not inevitable is that it will be severe.”Measures as simple as frequent hand-washing can help prevent the spread of the virus, public health experts say. Travel restrictions like those implemented in China have slowed its global spread, but probably won’t stop it, Fauci said.‘Precarious position’People in the US should prepare for disruptions to daily life, warned Nancy Messonnier, director of the CDC’s National Center for Immunization and Respiratory Diseases. In the event of a pandemic, schools may consider dividing classes into smaller groups or even shutting down, she said. Businesses will have to consider more telecommuting, and communities and cities may have to cancel mass gatherings.The WHO has already declared the outbreak an international public health emergency. The situation may be more difficult to define as a pandemic, according to Michael Ryan, executive director of WHO’s emergencies program. Most pandemics are caused by flu, and the transmission of coronavirus needs to be studied further, he said. While new cases are falling in China, the possibility of a global outbreak is real, he said.“It is time to do everything you would do in preparing for a pandemic,” he said in a press conference. “We’re still trying to avoid that eventuality and countries are having success in doing that. Let’s focus on what we can do.”The coronavirus outbreak looks nothing like the 1918 flu that killed an estimated 50 million people worldwide. The pandemics of Asian flu of 1956-1958 and Hong Kong flu in 1968 are each estimated to have killed from 1 million to 4 million people.Fortunately, unlike most flu strains, the new virus seems to leave children relatively unscathed, Schaffner said. That suggests fewer scenes like one he witnessed in the swine flu outbreak, when a five-year-old child died at Vanderbilt after being sent home from two other emergency rooms, he recalled.Treatments for flu have improved since then, and doctors are already testing antivirals and vaccines against the coronavirus. Yet other signs of a pandemic may still come, such as shortages of hospital beds and patients waiting in hallways waiting for attention, he said.“We’re at the edge of the cliff,” Schaffner said. “We’re in a more precarious position now than we were one week ago, and I see this week as determining what’s going to happen.” “We’re on the knife-edge,” said William Schaffner, a Vanderbilt University infectious disease specialist who’s been through the Asian flu, Hong Kong and swine flu pandemics.Two months after emerging in China’s Hubei province, the coronavirus has hit at least four continents, with rising case counts and huge responses in Iran, South Korea, Italy and Japan. More than 80,000 cases have been reported, including some 2,800 deaths. Authorities in the US and Thailand are warning about wider outbreaks in their countries.Yet most of the cases and clusters are traceable, according to the World Health Organization, meaning that for the most part community spread outside China is rare. Questions over the nature of the virus underscore WHO’s reluctance to call the outbreak a pandemic just yet, especially while there are early signs of slowed or stopped transmission in some countries.A pandemic doesn’t have a formal numerical definition, said Schaffner, who has advised the US Centers for Disease Control and Prevention on infections. It’s an epidemic that becomes global, spreading in multiple countries. In most cases, measures to contain the epidemic in one region or country have failed, and the goal switches to mitigation — trying to ease the pain.center_img Topics :last_img read more

first_imgNew Delhi: The situation confronting Mayank Agarwal in the Australia tour was immense. Agarwal, who was initially not picked in the side for the Tests, was called up as an emergency back-up following Prithvi Shaw’s failure to recover from an ankle injury. In the Melbourne Test, with the series level 1-1, Agarwal was given his debut cap and he was chosen to open the batting with Hanuma Vihari, the first time that India had opened with two new players after a long time. However, Agarwal responded with a brilliant 76 in the first innings and a tough 42 in the second innings as India won the Melbourne Test by 137 runs. In Sydney, Agarwal blasted 77 to confirm his credentials at the top of the Indian batting line-up.Speaking to PTI after returning home from Test series in which India won for the first time Down Under, Agarwal said he could not have hoped for a better start. “It was (special) to make my debut at the MCG and most importantly, to win the Test series in Australia. We became the first team from the sub-continent to win a series in Australia. There can’t be a better start than this,” Agarwal said.Read More | India to play 5 ODIs, 2 T20Is at home vs Australia in February-MarchThe right-hander’s aggressive batting prompted comparisons with Virender Sehwag, who had revolutionised the way India’s approach to batting would be in the longest format of the game. However, Agarwal brushed aside the comparison, saying, “I am not a fan of comparisons but he is one of the greats of Indian cricket. I just like to go in the middle, give my best and see what comes out of it. Having said that, if I could do even half of what he (Sehwag) did, I will be happy,” Agarwal said.Read More | Mitchell Marsh to miss first ODI against India due to illnessNew Zealand A tour luckyWith Shaw being ruled out of the Australia tour after failing to recover from his ankle injury, Agarwal was playing for India A in the series against New Zealand and said it was sheer luck that he got picked in the side. “I went there with a plan and I am glad it came off for a bit. I thought Australia was a top-class bowling unit. They play their cricket hard and bring out the best in you. You can’t pick out a bowler. Everyone was good and you have to be on top of your game to face them. Playing in New Zealand did help a lot. It was a tremendous learning experience. The conditions weren’t same but similar to Australia. There was a lot of pace in the wickets and New Zealand A had international bowlers in their line-up. So, it was good that I got to play there before the Australia series,” Agarwal added.Read More | Ashutosh Aman breaks Bedi’s record for leading Ranji wicket-takerAfter not being picked in the West Indies series after a brilliant domestic season, Agarwal could have been forgiven for feeling frustrated.

I cannot compare my journey to somebody else’s. There are things which are beyond your control and I don’t like to focus too much on them. I am just glad and grateful that I have got to represent the country,” Agarwal said.
