Cephalopods and mesoscale oceanography at the Antarctic Polar Front:satellite tracked predators locate pelagic trophic interactions

first_imgPredator data and exploratory fishing in the Scotia Sea have revealed the presence of cephalopod stocks in the Antarctic Polar Frontal Zone (PFZ). This is a vast, remote region where large epipelagic cephalopods aggregate into highly mobile schools making them difficult to locate and sample. We used satellite tagged predators and shipboard acoustics for coarse and fine scale location of cephalopod concentrations, and sampled them with commercial and scientific nets to determine the relationship between cephalopod distribution and mesoscale oceanographic features at the PFZ. Satellite tags were attached to 9 grey-headed albatrosses Diomedea chrysostoma, breeding at Bird Island, South Georgia, to monitor foraging at sea in January-March 1994. A foraging area at the PFZ, north of South Georgia, was located, an acoustic survey undertaken and a fixed station established where acoustic targets were found. A net survey was carried out with a commercial pelagic trawl, a rectangular midwater trawl 25 m2 (RMT25), a horizontal multiple plankton sampler and a neuston net. Acoustic layers were targeted and the RMT25 sampled 200 m layers to 1000 m in daylight and darkness. Cephalopods were simultaneously recovered from food samples fed to D. chrysostoma chicks at Bird Island. Two CTD transects, approximately normal to the major current flow, were undertaken across the PFZ and remote-sensed sea-surface temperature images from NOAA polar orbiting satellites were obtained aboard ship. The pelagic trawl sampled a cephalopod community that closely resembled that exploited by D. chrysostoma. The largest and most conspicuous species was the ommastrephid squid Martialia hyadesi which is the most important cephalopod prey species. Net-sampled M. hyadesi had been feeding on crustaceans and mesopelagic fish. The cephalopod community was sampled in a feature, interpreted as a warm core ring, in an area characterised by mesoscale features associated with the bathymetry of the northern end of the Northeast Georgia Rise and near a gap in the Falkland Ridge. The association of these mesoscale features with the bathymetry suggests that they may be predictable foraging locations for the cephalopods and their predators.last_img read more

Sharper image

first_imgA new microscopy method could enable scientists to generate snapshots of dozens of different biomolecules in a single human cell at once, a team from the Wyss Institute for Biologically Inspired Engineering at Harvard University reported Feb. 2 in Nature Methods.Such images could shed light on complex cellular pathways and potentially lead to new ways to diagnose disease, track its prognosis, or monitor the effectiveness of therapies at a cellular level.Cells often employ dozens or even hundreds of different proteins and RNA molecules to do a complex job. As a result, cellular job sites can resemble a busy construction site, with many different types of cellular workers coming and going. Today’s methods can typically spot at most three or four types of these tiny workers simultaneously. But to truly understand complex cellular functions, it’s important to be able to visualize most or all of those workers at once, said Peng Yin, a core faculty member at the Wyss Institute and assistant professor of systems biology at Harvard Medical School (HMS).“If you can see only a few things at a time, you are missing the big picture,” Yin said.Yin’s team sought a way to take aerial views of job sites that could spot dozens of types of biomolecules that make up large cellular work crews.To capture ultra-sharp images of biomolecules, the team had to overcome laws of physics that had stymied microscopists for most of the last century. When two objects are closer than about 200 nanometers apart — about one five-hundredth the width of a human hair — they cannot be distinguished using a traditional light microscope: The viewer sees a single blurry blob where in reality there are two objects.Since the mid-1990s, scientists have developed several ways to overcome this problem using combinations of specialized optics, special fluorescent proteins, or dyes that tag cellular components.As a graduate student, Ralf Jungmann, now a postdoctoral fellow working with Yin at the Wyss Institute and HMS, helped develop one of those super-resolution methods, called DNA-PAINT. DNA-PAINT can create ultra-sharp snapshots of up to three cellular workers at once by labeling them with different colored dyes.To visualize cellular job sites with crews of dozens of workers, Yin’s team, including Jungmann, Maier Avendano, an HMS graduate student, and Johannes Woehrstein, a postgraduate research fellow at the Wyss Institute, modified DNA-PAINT to create a new method called Exchange-PAINT.How it worksExchange-PAINT relies on the fact that DNA strands with the correct sequence of letters, or nucleotides, bind specifically to partner strands with complementary sequences. The researchers label a biomolecule they want to visualize with a short DNA tag, then add to the solution a partner strand carrying a fluorescent dye that lights up only when the two strands are paired. When the partner strand binds the tagged biomolecule, it lights up, then lets go, causing the biomolecule to “blink” at a precise rate the researchers can control. The researchers use this blinking to obtain ultra-sharp images.They then repeat the process to visualize a second target, a third, and so on. Then they overlay the resulting images to create a composite image in which each biomolecule — each cellular worker — is assigned a different color. This allows them to create false-color images that simultaneously show many types of biomolecules — far more than they could simultaneously visualize by labeling them with different colored dyes. These false-color images allow them to spot enough cellular workers at once to capture the entire scene.Passing the testTo test Exchange-PAINT, the researchers created 10 unique pieces of folded DNA, or DNA origami, that resembled the numerals 0 through 9. These numerals could be resolved with less than 10 nanometers resolution, or one-twentieth of the diffraction limit.The team was able to use Exchange-PAINT to capture clear images of the 10 different types of minuscule DNA origami structures in one image. They also used the method to capture detailed, ultra-sharp images of fixed human cells, with each color tagging an important cellular component — microtubules, mitochondria, Golgi apparatus, or peroxisomes.Yin expects that with further development, the method will be able to visualize dozens of cellular components at once.“Peng’s exciting new imaging work gives biologists an important new tool to understand how multiple cellular components work together in complex pathways,” said Donald Ingber, director of the Wyss Institute. “I expect insights from those experiments to lead to new ways to diagnose and monitor disease.”Ingber is also the Judah Folkman Professor of Vascular Biology at 
Harvard Medical School and Boston Children’s Hospital and professor of bioengineering at Harvard School of Engineering and Applied Sciences.last_img read more

H1N1 FLU BREAKING NEWS: Case counts, vaccine progress, situation in northern Canada, Australia holding steady, traveler quarantine

first_imgGlobal H1N1 flu count closes in on 30,000The global number of novel H1N1 cases grew by 895 yesterday, reaching 29,669 from 74 countries, including 145 deaths, the World Health Organization (WHO) reported today. Much of the increase was from new cases reported by Canada (532), Spain (131), Argentina (87), and Japan (31). No new countries appeared on the list, though media reports said today that Morocco has reported its first case, in a woman who had studied in Canada.[WHO update 48]US novel H1N1 cases near 18,000The US Centers for Disease Control and Prevention (CDC) reported today that the nation’s count of novel flu cases has grown to 17,855, an increase of 4,638 from its last report on Jun 5. Deaths reported to the CDC over the past week rose by 18 to reach 45. Wisconsin, Texas, and Illinois have the most cases, while New York has reported the most fatalities (13).[Current CDC numbers]Novartis, CSL report vaccine progressNovartis announced today that it has produced its first batch of novel H1N1 vaccine for testing. The company said it completed the batch weeks ahead of schedule by using cell-culture technology. Its production facility is in Germany, with another under construction in North Carolina. Meanwhile, CSL, an Australian company, said yesterday it would have its first vaccine batches ready in mid August, using a seed strain it developed for an egg-based vaccine, Bloomberg News reported.[Jun 12 Novartis press release]Cases mount in northern CanadaH1N1 cases in northern Canada’s Nunavut territory increased by 47 to a total of 143 yesterday, according to CBC News. Significant outbreaks were reported in several communities in the western and central parts of the territory, but most of the patients have recovered or are recovering, the story said. Earlier this week the World Health Organization voiced concern about a disproportionate number of severe H1N1 cases in some groups of indigenous Canadian people, particularly in northern Manitoba.[Jun 11 CBC News report]Australia holds steady on alert levels following WHO moveAustralian Health Minister Nicola Roxon said Australia would not raise its pandemic alert levels in response to the WHO’s pandemic declaration yesterday, according to the Australian Associated Press (AAP). Most of the country is at the “contain” stage, but Victoria, which has 1,011 of the country’s 1,336 cases, is at the “sustain” level, the story said. Roxon said the authorities would continue to try to delay community spread in areas that still have few cases.[Jun 12 AAP report]Incoming air travelers quarantined in CairoA dozen arriving airline passengers in Cairo were quarantined after two 9-year-olds were found to be feverish, according to the Kuwait News Agency (KUNA). One of the children arrived in Egypt from Jeddah, Saudi Arabia, and the other arrived from Dubai. Authorities quarantined the two children and their families, said the airport’s quarantine director, Dr. Hasan Shaban.

Arsenal overcome Liverpool challenge

first_img Press Association Santi Cazorla fired the Gunners ahead somewhat against the run of play on 19 minutes, lashing the ball home after his bullet header had come back off the post. Ramsey then made sure of all three points when on the hour he cracked in a sublime 25-yard half-volley for his 10th goal of an impressive campaign as Arsene Wenger’s side renewed belief ahead of next week’s European trip to Dortmund and Premier League game at Manchester United. Arsenal, without midfielder Jack Wilshere who had been troubled by an ankle problem, created the first opening on six minutes when Tomas Rosicky was played into the right side of the penalty area and his low shot across goal was pushed behind by Simon Mignolet. Liverpool, though, were soon on the offensive as Jordan Henderson waltzed all the way into the Arsenal penalty area, before scuffing his shot. The visitors then settled into a good spell of possession, as Arsenal chased shadows. Arsenal, though, swept into the lead on 19 minutes. A quick break down the right found Bacary Sagna on the overlap. His cross was behind Olivier Giroud, but fell perfectly for Cazorla on the penalty spot. Aaron Ramsey scored another superb goal as Arsenal beat Liverpool 2-0 at the Emirates Stadium to move five points clear at the top of the Barclays Premier League. All of the pre-match hype had been about what impact Reds forward Luis Suarez would have against the club which tried to sign the Uruguay forward for £40,000,001 in the summer. However, Arsenal answered the critics who had questioned their character for a sustained title bid following successive home defeats by Borussia Dortmund in the Champions League and after crashing out of the Capital One Cup against Chelsea on Tuesday night. The Spaniard’s bullet header beat Mignolet, but cannoned back off the post. Cazorla, though, was first to the rebound ahead of a static Martin Skrtel and lashed a fine half-volley back past the goalkeeper. Liverpool were understandably rattled after being so dominant – and were left further aggrieved when Suarez took a quick free-kick after being pushed over by Sagna, which released Daniel Sturridge who crossed for Henderson to tap into the net – only for referee Martin Atkinson to pull play back and book the Arsenal defender. Arsenal pressed again as Ramsey got into the left side of the penalty area and his low shot was palmed away by Mignolet at the near post. Reds boss Brendan Rodgers made a positive change for the second half as Aly Cissokho was replaced by midfielder Phillippe Coutinho. Suarez was released into the right side of the Arsenal box, but could only chip the ball across goal. Liverpool broke quickly down the left through Suarez, only for his deep cross to be blasted over at the far post by Henderson. There was a huge let-off for the visitors when a loose backpass from former Arsenal defender Kolo Toure was seized on by Giroud, who charged into the penalty area but chipped his shot wide. Giroud then just could not get on the end of a quick counter attack from Rosicky and Cazorla down the left. It was, though, 2-0 on 59 minutes as Ramsey cracked home another goal of the highest order. There seemed little danger when Mesut Ozil fed the Wales midfielder in a central position, some 20 yards out. However, as Toure backed off, Ramsey waited for the bouncing ball to sit up before dispatching a dipping volley over Mignolet and into the roof of the net. Rodgers decided to make another attacking change as he sent on Victor Moses for Jon Flanagan. Suarez shaved the far post from a curling effort with the outside of his right boot as the Reds looked for a way back into the match. Mignolet saved low at his near post to deny Ozil after the German weaved into the left side of the Liverpool box. Kieran Gibbs hobbled off after a burst down the left flank, and had to be replaced by club captain Thomas Vermaelen. Arsenal were pressed back during the final 10 minutes, with Suarez dragging a shot wide when clean in on goal – but the hosts had already done enough to record the most impressive of their eight Premier League wins so far. last_img read more
