Weird Jellyfish Eyes: Are They Missing Links?

first_img“Missing Link?” asks the cover of Nature May 12, next to what looks like an alien head with a giant eye staring out.  The article by Nilsson et al.1 suggests that the box jellyfish has optical sensors that could represent primitive eyes that evolved before the more advanced eyes of vertebrates.  Most of us don’t think of jellyfish with eyes; “In the light of the current interest in early eye evolution,” they say, “the uniquely evolved eyes of box jellyfish have been neglected.”  But just how primitive are these strange eyes? Cubozoans, or box jellyfish, differ from all other cnidarians by an active fish-like behaviour and an elaborate sensory apparatus.  Each of the four sides of the animal carries a conspicuous sensory club (the rhopalium), which has evolved into a bizarre cluster of different eyes.  Two of the eyes on each rhopalium have long been known to resemble eyes of higher animals, but the function and performance of these eyes have remained unknown.  Here we show that box-jellyfish lenses contain a finely tuned refractive index gradient producing nearly aberration-free imaging.  This demonstrates that even simple animals have been able to evolve the sophisticated visual optics previously known only from a few advanced bilaterian phyla. (Emphasis added in all quotes.)Yet these sophisticated eyes do not focus sharply on a retina, they say:However, the position of the retina does not coincide with the sharp image, leading to very wide and complex receptive fields in individual photoreceptors.  We argue that this may be useful in eyes serving a single visual task.  The findings indicate that tailoring of complex receptive fields might have been one of the original driving forces in the evolution of animal lenses.The paper claims that these jellyfish figured this out on their own: “From the unique crystallin proteins we know that at least the lenses have evolved independently in box jellyfish,” they say, noting that “Making good lenses seems to be a demanding task, because only few animal phyla have accomplished it.”  Also, they contain a number of eye-like parts: “All major components of a typical camera-type eye are present: a cornea, a lens, a retina, a pigment layer and an iris.”  The tiny lenses, about a tenth of a millimeter across, are spherically symmetric; yet by means of a variable index of refraction, they are able to form “good images.”  The packing density of the specialized crystallin proteins provides the refractive index gradient.  The researchers measured some pretty remarkable optical qualities, but also some aberration:Tracing rays through the refractive-index gradient of the upper eye reveal nearly perfect focusing for all ray positions (Fig. 2).  For such a minute eye it is surprising to find well-corrected, aberration-free imaging, otherwise known only from the much larger eyes of vertebrates and cephalopods.  The gradient in the upper-eye lenses comes very close to the ideal solution.  The lenses of the lower eye have a less ideal gradient and consequently display some spherical aberration (Fig. 2e, f).  It is the homogeneous lens core and steep peripheral gradient that results in positive spherical aberration in the lower eye.Surprisingly, both kinds of eyes are severely under-focused.  Is this due to clumsy eye geometry, or could there be a reason for under-focused eyes for a jellyfish?Another, more likely, interpretation is that the eyes are ‘purposely’ under-focused to remove high spatial frequencies (fine image details) from the retinal image, much as occurs in insect dorsal ocelli.  If the arrangement is indeed a spatial low-pass filter, it would help the animals to detect the large and stationary structures of their visual environment, but would leave unseen the plankton and small particles floating with the current.  Assuming that the lens eyes have evolved to allow the jellyfish to remain in nearshore habitats and to avoid swimming into obstacles, a low-pass filtering of image structure would make sense.It is not known how the visual information is processed.  The authors suggest that the data is filtered early in the jellyfish eye, not requiring a complex brain:In box jellyfish we find these large complex receptive fields at the level of photoreceptors, indicating that the eyes might be specialized for a specific task only and that this allows complex filtering of information much earlier than in more general visual systems.  The fact that box jellyfish have four different types of eye gives support to the idea that each eye type is highly specialized.So how do box jellyfish fit into the story of eye evolution?The early evolution of animal visual systems is likely to have started out with eyes that were involved only in single visual tasks.  In this perspective it is interesting to note that high visual acuity is not necessarily desirable.  The lens eyes of box jellyfish indicate that there might be visual tasks best served by a blurred image.  Evolution of sophisticated eyes might therefore be a process with discrete stages representing the sequential addition of visual tasks.  Our results also indicate that advanced lenses with graded-index optics might have evolved for tailoring complex receptive fields and not just for improving sensitivity or acuity.Not many science reporters seem to have given this story a glance.  Michael Hopkin in News@Nature avoided speculating that these were missing links, titling his review “Box jellyfish show a keen eye.”  Yet New Scientist made evolution its centerpiece: “Multi-eyed jellyfish helps with Darwin’s puzzle,” the title states, claiming it represents a “possible path from simple to complicated” eyes.  Given the blurry imaging system of the box jellyfish, the article concludes, “From here it would be an easy step to evolve an image-forming eye.”  Susan Milius, on the other hand, writing for Science News,2 warned against such speculation.  “Biologists need to be careful in working out the evolutionary implications of the new study,” she says, quoting Alan Collins of NOAA.  “The eyes of box jellyfish, cephalopods such as the octopus, and vertebrates seem to have arisen independently.  So, unraveling the evolution of box-jellyfish eyes may not reveal the particular path of eye evolution for other lineages.”  Her article contains a stunning color picture of the box jellyfish, eyes and all.    1Nilsson et al., “Advanced optics in a jellyfish eye,” Nature 435, 201-205 (12 May 2005) | doi: 10.1038/nature03484.2Susan Milius, “Built for Blurs: Jellyfish have great eyes that can’t focus,” Science News, Week of May 14, 2005; Vol. 167, No. 20, p. 307.Oh, how the Darwinists would love to find a sequence of complexity in eyes, to ease Chairman Charlie’s stomach pains when contemplating the wonderful designs in nature.  But this story can’t help.  The jellyfish eyes appear over-designed for their task (see 06/19/2002 entry).  These remarkable optically-near-perfect structures are well adapted to the needs of the organism.  Perfect focus would be a drawback for the jellyfish.  It would create an image crowded with irrelevant details.  Instead, it has a “low-pass filter” to help it see what it needs to see: large, stationary objects so that it can avoid obstacles and find prey in its habitat.  If an animal has a structure that meets its needs and is well designed, is it not a non-sequitur to say it is evolving?  Did the Darwinists find a gradual sequence of intermediates leading from primitive eyes to complex eyes?  No.  Brittlestars (see 08/23/2001), trilobites (09/18/2003) and even sponges (08/20/2003) exhibit optical perfection, yet none of these are on a phylogenetic line – evolutionists claim all these things evolved independently (and suddenly, too, considering they burst onto the seen during the Cambrian, without ancestors).  So instead of helping Charlie sleep better, this story gives him more indigestion: his tale now needs multiplied miracles of chance and natural selection to keep from falling apart.    We need to get rid of the useless Darwinspeak in biological research, and focus instead on the functional information and adaptive excellence of each species.  Arranging the tools in your garage into a hypothetical evolutionary sequence does nothing to help you use them better.(Visited 17 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

Four Imperatives for the Sales Leader

first_img Essential Reading! Get my 3rd book: Eat Their Lunch “The first ever playbook for B2B salespeople on how to win clients and customers who are already being serviced by your competition.” Buy Now Each of these four imperatives ensures that your sales force is effective at the individual level. They’re all necessary to building and sustaining a high performing sales force.A Prospecting Plan that Opens Opportunities: It’s one thing to expect your salespeople to prospect. Providing your sales force with a prospecting plan and the necessary tools to build the relationships that open opportunities is quite another. I told the story here about one sales organization that provided their salespeople with “all the leads they could handle” by throwing the telephone book on their desks.The sales force needs to know and understand their real targets. They need tools to nurture and open relationships. They need ideas that create value for their prospective clients. And they need a campaign that allows them to succeed overtime by persisting (and not by merely being a nuisance).If you want the sales force to do more prospecting, then you need to provide them with the plan for doing so.Differentiation with a Difference: I can’t tell you how many salespeople I’ve asked who have no answer for the question, “What makes you and your offering different?” If they can’t answer this question when I ask, I doubt they do any better when a prospective client asks.But even if a prospective client never asks directly what makes you different, it’s your differentiation that drives a wedge between you and your competitors. It’s the differences that make a difference for your clients that make you worth paying more for. Differentiation is why your prospective client would choose you over your competitors (or the status quo).If you want the sales force to differentiate in a meaningful way, you have to provide them with the differentiation strategy, language, and examples.Effective Sales Interactions: The salesperson sitting across from your prospective client has the greatest impact on the outcome of an opportunity. That’s where you win or lose. You aren’t there when those interactions happen. You need to be certain that each interaction is effective.You need a sales process that moves prospective clients from target to close. Your process needs to create value for your prospective client at each stage of the buying journey. Your salespeople need the mindset, the skill sets, and the tool kits to create the highest level of value. And it’s certain they need business acumen and situation knowledge to create that value.If you want to make your number, it’s improving that you improve the effectiveness of the sales force.Excellent Sales Managers: Generals may provide the vision, goals, and strategy, but it’s Colonels that execute and ensure those outcomes. In sales, that’s the first line sales manager.You need sales managers that are true leaders in their own right. You need to provide them with a model for coaching their teams—and the individual who make up that team. You need to provide them with the space and time to work on the results of each individual, and you need to protect them from serving the organization at the expense of their people.If you want a high performing sales organization, it starts with excellent sales managers.You can’t afford not to have the right opportunities, the inability to differentiate, the inability to create value during each sales interaction, or a leaderless sales force.QuestionsWhat do you provide the sales force in the way of an effective prospecting plan that helps them open new opportunities?How do you help your sales force explain the differences that make a difference for your client in a way that is compelling to your prospective clients?What do you do to ensure that your sales force is improving their ability to create value during every sales interaction?Does your sales force have the first line sales managers that it needs? Are they getting the best performance form their team and each individual team member?last_img read more

Exclusion from NRC drives Assam lawyer to take extreme step

first_imgExclusion from the updated National Register of Citizens (NRC) reportedly drove a 74-year-old lawyer in north-central Assam’s Kharupetia to death on Sunday. This was the third such case since the publication of the complete draft of the NRC on July 30.Family members found Nirod Kumar Das hanging in his room after returning from his routine morning walk. An autopsy confirmed death by hanging, said Chandan Goswami, incharge of the local police station.Raju Saha, the brother-in-law of the deceased, said Mr. Das appeared disturbed since his name was dropped from the NRC. “His name had figured in the first partial list (published on December 31, 2017) but the local NRC processing centre handed him a document two months ago saying his name has been put on hold as he has been declared a foreigner,” he said.Family members in NRCAll other members of his family – wife, three daughters, their husbands and children – and most of his relatives figure in the NRC. A note left behind by Mr. Das said he was ending his life to “escape the humiliation” of being marked a foreigner after the NRC process. “He blamed no one, listed five people he owed up to ₹1,200 and requested us to return the money,” Mr. Saha said. The septuagenarian had studied law after a 34-year teaching stint at the local government school. A decade ago, he began practising at the district court in Mangaldoi town, 16 km west of Kharupetia.“He was one of the most jovial members of our bar association. But he underwent a drastic change in the last two-three months, and would often mumble about his uncertainty as a citizen of Assam,” Mangaldoi-based lawyer Billal Hussain told The Hindu after attending Mr. Das’s cremation on Sunday evening.The Mangaldoi Bar Association has scheduled a condolence meeting on Monday.On September 3, Mr. Das had lamented in local publications about his “statelessness” and how he felt let down by the very system he was trying to uphold.“My legal documents since 1956, my father’s legacy data of 1966 and my own of 1971 (the cut-off year for detecting and deporting illegal migrants), and by government service mean nothing to the authorities. How can a man prove his citizenship if they are determined not to accept my documents provided by the government?” he wrote.The Assam State Committee of CPI(M) on Sunday wrote to the Supreme Court seeking the inclusion of all 15 admissible documents for the claims and objections phase of NRC that started from September 25.IIT-Guwahati helpline for students in collaboration with Saathi: 8486814024.

Getting a result against the Chinese is paramount for Eriksson’s side if it wants to advance to the last 16.Few expected the Azkals to stay competitive against a Korean team that regularly plays in the World Cup and only recently stunned former World Cup champion Germany, 2-0.But the Azkals were hardly fazed by the quality and experience of a Korean side, which had established players in Ki Seungyeung of Newcastle United and Lee Chungyoung, formerly of Crystal Palace.The tactical brilliance of the staff led by Eriksson and deputies Scott Cooper and Chris Greatwich allowed the Azkals to cope with the Korean assault for majority of the match.The Azkals defended deep, but they tracked runs off the ball and produced a solid defensive block that hardly allowed the Koreans to break through. On the counter, they proved dangerous with Schrock and Patrick Reichelt threatening on the right and Patino holding up the play to relieve the pressure.ADVERTISEMENT Sports Related Videospowered by AdSparcRead Next It took some tweaks and the introduction of Lee early in the second half for Korea to finally break down the Azkals.Lee, who played four seasons in the Premier League, praised the Azkals for their gallant stand.“Everyone thought Korea will win this game, but we saw in the first half that it was not easy,” said the midfielder. “It was a tough game for us. I’m happy to get a result, but the Philippines is good. They have a good future in this tournament.”The three-man defense anchored by Alvaro Silva put bodies on the line just to deny the Koreans opportunities, while Michael Falkesgaard produced three big saves to keep the Azkals in the match up until the late stages of the match.Patino led the line ferociously and provided the Azkals an attacking outlet when they recover the ball from deep positions, but his finishing let him down particularly in the second half when his tamed effort failed to beat Kim Seunggyu on the Korean goal when the match was still goalless.“We kept it nil nil for a long time,” said Younghusband, who came on in the 88th minute.“The longer it got, the more confidence it gave us. Every player had to work in this team. If you lose concentration or you sleep, South Korea will take advantage.”Still, it was a debut to remember for a Philippine team that struggles to get support for the sport back home.“The feeling is incredible: The whole atmosphere,” said Reichelt. “You can feel that this was all a different stage. And we showed that we belong in this stage.”“I’m happy with the performance; but I’m also sad because we could have gotten something out of it,” said Azkals manager Dan Palami. “But if somebody told us before the game that it was going to be just 1-nil, I would take it anytime against a team like South Korea which is always in the World Cup. It gives us encouragement and motivation to do better in our next games.”center_img Don’t miss out on the latest news and information.

AC Milan suffer record €126m annual losses

first_imgAC Milan have announced record losses of €126 million (£111m/$146m) for the 2017-18 financial year.The club’s latest statement shows a €53m (£46m/$61m) drop on the previous year and brings the club’s consolidated losses over the last 14 years to over €730m (£639m/$845m), with €460m (£403m/$533m) of that total accounted for in the last five years.  Milan published half-year accounts earlier this year which showed a six-month loss of only €22.3m (£19.5m/$25.8m) against €39.3m (£34.4m/$45.5m) for the same period 12 months earlier.

Since then, however, Milan have undergone a change in ownership, with US hedge fund Elliot assuming control of the club after Li Yonghong missed deadlines to repay the company loan fees he had taken to complete his takeover of the club from Silvio Berlusconi in 2016. The loan taken out by Li carried a double-digit interest rate, while figures show that expenses rose 22.3 per cent during the first and only full year of the Chinese businessman’s ownership.Since stepping in for Li, Elliot has made major changes to the senior management team, with Ivan Gazidis recently recruited from Arsenal to become Milan’s new Chief Executive. Club legends Paolo Maldini and Leonardo have also been brought in to work on player acquisition.The club went on a major spending spree during the most recent transfer window, shelling out more than €200m (£175m/$232m) on signing new players over the summer, although some of those payments are postponed until future years.Milan’s financial results for 2017-18 dwarf those of their cross-city rivals Inter, who recently revealed losses of €18m (£16m/$21m) for the same year.last_img read more

Notley says BC pipeline court challenge illogical harmful if successful

first_imgEDMONTON – Alberta Premier Rachel Notley says the B.C. government’s attempt to get court backing in a bid to thwart the Trans Mountain pipeline expansion would put Canada in “economic gridlock” if it succeeds.British Columbia is seeking control over increased levels of diluted bitumen coming into the province because of concerns of increased risk to the environment.Notley says if the B.C. Court of Appeal agrees the government has the right to do so, that would open the door to provinces regulating all kinds of goods coming in from the rest of Canada — to the detriment of the economy as a whole.Notley says her government will seek intervener status in the court proceedings and she expects B.C. will fail.She also says the legal move is illogical.She notes that B.C. wants control over more bitumen coming into the province via pipeline on environmental safety grounds, but is OK with current levels already coming in.“It makes no sense,” Notley said Thursday from Slave Lake, Alta. “If bitumen were so hazardous, why would we only be looking at the (extra) incremental bitumen that’s in the new pipeline?“This isn’t about environment. This is about the new pipeline … I think the courts will see right through it.”In Calgary, United Conservative Leader Jason Kenney said the court reference is one more delay tactic in a pipeline project that is already on the edge of an abyss.Operator Kinder Morgan has stopped extra spending on the project and is to decide by the end of May if it will go forward, given the opposition from B.C.Kenney said Notley’s government has not been strong enough to dissuade B.C. or to get Prime Minister Justin Trudeau’s government to take action on a project that it already approved.“None of this gives Kinder Morgan the certainty it needs to proceed with this $7-billion, job-creating investment that would help us get a fair price for our oil,” said Kenney.Companies in this story: (TSX:KML)last_img read more

Dhoni Captain Uncool

first_imgIt’s a rare feat and a rare sight too. Chennai Super Kings’ MS Dhoni achieved a major landmark on Thursday to become the first-ever captain in IPL cricket to win 100 matches. “The history of the world,” wrote Thomas Carlyle, “is but the biography of great men.” And if his ideas have been discredited since, in sport, at least, they’ve still some truth to them. For the rest of his life as captain of the Indian cricket team, Dhoni has led India to victory in the 2011 World Cup and the 2013 Champions Trophy. He is the man who brought himself on to bowl for four overs in the Champions Trophy semi‑final against Sri Lanka, took off his gloves so that he could better carry out a run-out off the last ball to beat Bangladesh in the World T20 meet. He is also the one to promote himself up to No. 5 in the order during the World Cup final in Mumbai’s Wankhede Stadium though he had barely made a run all tournament long. Dhoni is the only cricketer who has been picked as one of Time Magazine’s 100 most influential people on the planet. His aggression, attitude and captaincy have shaped the entire landscape of the modern game. He is a winner, a great mentor, charming and humble as always. But his recent feat was marred by a long debate. An emotionally-charged Dhoni, who had just been dismissed after a stunning performance, stormed on to the ground from the Chennai Super Kings’ dugout and confronted the umpires on why they had failed to call an above-the-waist delivery from Rajasthan Royals’ Ben Stokes a no-ball. Dhoni argued that Ulhas Gandhe, the umpire standing at the bowler’s end, had raised his arm to signal a no-ball. But he quickly realised that it was not his call and reversed his decision after square leg umpire Bruce Oxenford considered it a legal delivery. Oxenford stood his ground and refused to go upstairs to the third umpire which was kind of unfair. Dhoni was furious at Gandhe for backtracking after initially signalling it as a no-ball. However, CSK eventually beat Rajasthan Royals by four wickets in a last-ball cliffhanger. Dhoni has been fined 50 per cent of his match fees for breaching the IPL Code of Conduct. With the pressure getting to him, MSD totally lost his cool and the world finally got a glimpse of ‘Uncool Dhoni’. Whoever the player is, he is definitely not bigger than the game. The decorated captain set the wrong precedence and considering his level of maturity and composure, he will surely realise that he shouldn’t have done it in the first place.last_img read more

Womens Basketball No 8 Ohio State falls 6960 to No 14 Duke

Ohio State redshirt junior guard Sierra Calhoun launches a shot during the first half of the Buckeyes’ game against Quinnipiac on Nov. 15. Credit: Colin Hass-Hill | Sports EditorThe No. 8 Ohio State women’s basketball team came back from a 17-point deficit to No. 14 Duke midway through the third quarter to tie the game with 9:15 remaining in the fourth quarter. But the Blue Devils (6-1) responded with a nine-point run to pull away down the stretch en route to a 69-60 victory against the Buckeyes (7-2) Thursday night in Durham, North Carolina, in the ACC/Big Ten Challenge.Guards Lexi Brown and Rebecca Greenwell each scored 19 points for Duke. The Blue Devils won the rebounding battle, holding a 49-30 advantage. This led to a 36-18 edge in points in the paint.The Blue Devils led by 17 points in the third quarter, but did not score for the final six minutes of the third quarter. The Buckeyes slowly pulled even with Duke. But Ohio State struggled to get its offense going in the fourth quarter, missing 11 of its final 12 shots, and turning the ball over five times in the last nine minutes.Duke held Ohio State to its lowest scoring total of the season. The Buckeyes shot just 32 percent from the field and 28 percent from beyond the arc, while the Blue Devils made 46 percent of their shots and 47 percent of their 3-point attempts.Senior guard Kelsey Mitchell led Ohio State with 24 points, but played inefficiently. She made just 9-of-27 shots and hit 4-of-17 3s. Redshirt senior guard Linnae Harper added 12 points and eight rebounds. The Buckeyes forced the Blue Devils into 21 turnovers, including 12 steals, despite their lack of offensive rhythm. Ohio State never led in the entire game. read more
