Controversy stikes Oxford local council elections

first_imgOxford’s local election campaigns have been struck by controversy as polling day nears, after Liberal Democrat campaigners have accused the Labour candidate for the University Parks division of “lies and slander” in negative campaigning about her Liberal Democrat opponent.The Labour candidate is Dr Emma Turnbull, with the Liberal Democrats represented by Lucinda Chamberlain, an Oxford student studying PPE at Brasenose.A leaflet distributed last week by the Labour campaign claimed that Chamberlain did not “[w]ork hard for Remain during the EU referendum.”Chamberlain, speaking to Cherwell, said this was a “blatant lie”, and an attempt to mislead voters. She maintains that she “gave 100% to Oxford students for Europe and… did everything in [her] power” for a Remain vote, including “being an incredibly dedicated phone bank manager”.The claims were also strongly rejected by Harry Samuels, who was co-Chair of the Oxford University Liberal Democrats during the EU referendum. Samuels told Cherwell: “It’s deeply disappointing that Labour have resorted to outright lies about a fantastic, hard-working, pro-EU candidate in this election. Lucinda worked extremely hard in our campaign to remain in the EU.”Samuels is also running to be a Liberal Democrat councillor in Cowley.Chamberlain’s campaign has since produced a video detailing her work during the referendum campaign, which included volunteering in call centres and canvassing on the streets of Oxford.Chamberlain has also received support from followers via [email protected]_Labour lied about @libdems Lucinda in #uniparks saying she didn’t campaign to remain. Here’s just a few photos of her working hard!— Andy McKay (@andygmckay) April 27, 2017Turnbull declined to comment on the allegations, and has thus far chosen not to apologise. A Labour Party spokesperson told Cherwell: “We are proud of our positive and progressive County Council campaign, which has prioritised increased investment in social care services and tackling Oxfordshire’s housing crisis.”The Electoral Commission’s outline of electoral offences says: “It is an illegal practice to make or publish a false statement of fact about the personal character or conduct of a candidate in order to affect the return of a candidate at an election.”last_img read more

Fresh flavours

first_imgFrom Rondo to Rademaker, Panettone to pizza, the AB Tech Expo show, which recently took place in Milan, was a showcase for equipment and some new flavour combinations.There was much interest in Tagliavini’s new Rotovent rack oven, the RVT68, which is a smaller size than its predecessor, uses less electricity, and comes in three versions, depending on goods output. But the major feature is that the rack oven is delivered in two ready-made sections. Giovanni Gaibazzi, export manager and son of the com-pany’s founder, tells British Baker: “We put the two sections together in under one hour; all the baker has to do is plug it in, there is no loss of production because, in under one hour, the oven is working.”Gaibazzi explains that the company exports all over the world, with the UK a major market. Rotovent RVT68 is suitable for trays of 60×80 or 65×85 and measures 130x170x205cm. The doorway is 75cm. Energy-saving is standard.Sottoriva’s equipment is known worldwide. Its latest Athena divider/rounder is claimed to be the only machine that can form round doughballs from 25g up to 700g in other words from hamburger buns up to large baguettes. Aimed at large wholesale and industrial bakers, it can be converted very fast in just two minutes.Managing director Igino Sottoriva tells British Baker: “This flexibility is not common in the market. The dough hopper takes up to 250kg of dough and dividing is virtually stress-free. Operating one to six rows, there is no need for an elevator, and a tipper is better for the dough.”Deals being doneUK representative for Sottoriva Andy Turner of Tecnobake says: “A contract with a major UK supermarket is about to be signed and a major wholesale bakery in Kent is installing a Tecna 240 ciabatta line. The efficiency of Sottoriva’s equipment is known and respected.”Pietroberto’s latest rack oven series the PBR-H, designed for the UK, is available through UK industrial sales manager Alan Burgess. “When commissioning the rack oven, it is easy to balance air distribution laterally and vertically, which is very important for overall heat distribution over a variety of products. These include flatbreads, standard breads and pastries,” says Burgess.”The model number determines the size of oven, which is designed for UK tray size 30×18,” he explains. As well as a very easy-to-understand panel, allowing the operator to set temperature, baking and steam times, the Pietroberto offers an optional computer control panel with LCD display for 100 recipes. The double-glazed door ensures fingers do not get burnt.Burgess adds: “Another asset is the fact the mechanism for driving the turntable is at the top so there is the advantage of no stress at the bottom of the oven. This ensures a smooth operation, a longer working life and no ingress of water to the electronics during high-pressure water cleaning.”Universal appealRondo’s Curl & More was launched at IBA and is proving particularly successful, according to salesman Urs Wullschleger, because customers like the universality. It can make all sizes of croissants, filled and unfilled. “But what they particularly like is the filling ratio of 1-1 50g of dough weight and 50g of filling. That is unique,” says Wullschleger. The machine also makes, breads and baguettes up to 400g and soft, curved sticks.One of the advantages of visiting overseas shows is the chance to pick up on new flavours.FlavoursOn the cake side, panettone used to come in plain versions, or with dried fruits and, more recently, containing chocolate chips. But now lemon-flavoured panettone is everywhere! And, right next to it, also filling the bakery shelves of major shop chains like Rinascente, is apricot and ginger panettone.On the bread side, one very popular new product is the bacon twist. It is available in snack bars and restaurants and makes a great accompaniment to meals. Rondo and Sottoriva equipment are among those that would cope easily with the shape. The crumb, not crust, is simply dotted with tiny pieces of bacon that, once you have bitten through the light, almost crumbly crust, render a delicious, light flavour that is very more-ish.DemonstrationsMasterclasses at AB Tech’s demonstration theatres showed not only panettone, but how to make the perfect pizza, with long-sliced courgettes proving a popular topping and even slivers of savoury pumpkin to add a topical autumnal flavour.On the quiche and savoury tart side, egg, minced courgette and onion was the in-flavour, with samples disappearing faster than they could be made and visiting bakers coming back from more. And while frozen breads from companies such as ’Bakery’ are growing in supermarkets and foodservice, craft still reigns supreme.Finally, the Petra crusty loaf (left) has a simple wraparound label. It clearly identifies the name of the loaf on one side and, on the other, gives a tantalising description of the loaf itself marketing at its best. Two into one The AB Tech Expo show in Milan, Italy from 23-27 October featured the biggest range of Italian machinery manufacturers you could hope to find under one roof.But Italy still has two shows SIAB in May and AB Tech in October both every three years. If they were to unite, or reunite after their earlier split, they would be a massive tour de force. Mondial Forni is among those loyal to SIAB. Polin, with a larger presence at SIAB, is beginning to take display space at AB Tech, while companies such as Sottoriva are dedicated AB Tech followers. But it is not just organising committees and craft bakery associations competing, it is also Veronafiera and Milanofiera, the city hosts, so compromise will be difficult. But visitors (like exhibitors) are split, so compromise is essential or Germany’s IBA will grow at the expense of some great Italian companies whose market is equally worldwide.Paolo Zarantonello, MD of Rondo in Italy, is president of SIPAN, an organisation for manufacturers of bakery, pastry, pizza and pasta machinery, which has 75 members. He is the man charged with finding a way through the stand-off. Aldo Tagliabue, the founder and organiser of AB Tech Expo in 2007, was the man who also founded and built up SIAB many years earlier, before SIAB’s supporting organisation, Promopan, awarded the SIAB show to Veronafiera.last_img read more

Remi Garde watches Villa slip to seventh straight loss as Tottenham climb table

first_imgNew Aston Villa manager Remi Garde watched his team lose 3-1 at White Hart Lane on Monday night as Tottenham moved up to fifth in the Premier League table. Instead, Spurs’ uncharacteristic sluggishness left an opening. Leandro Bacuna had already struck the post when Ryan Mason gifted fellow substitute Jordan Ayew possession in midfield, and the forward ran into space before striking a shot which deflected off Toby Alderweireld, beyond Lloris and into the bottom left corner. Ayew immediately threatened with another effort from midfield, but as Villa pushed forward they gifted space to Spurs. Christian Eriksen and Erik Lamela used it to set up Harry Kane, who with time and space effortlessly curled into the top right corner. The result not only consigned the visitors to further misery, it also meant their worst start to a top-flight season since 1919. TWEET OF THE MATCH “Well how good was that 3-1 to Spurs. Play the kids on Thursday as we need to stuff Arsenal. If we do that we are contenders for 4th” – Tottenham fan Lord Sugar (@Lord_Sugar) is willing to risk losing points against Anderlecht in the Europa League to ensure Spurs are fresh for the north London derby. PLAYER RATINGS Tottenham HUGO LLORIS: 7 (out of 10) KYLE WALKER: 6 DANNY ROSE: 5 TOBY ALDERWEIRELD: 7 JAN VERTONGHEN: 6 ERIC DIER: 5 DELE ALLI: 7 MOUSA DEMBELE: 7 CHRISTIAN ERIKSEN: 7 ERIK LAMELA: 6 HARRY KANE: 7 SUBSTITUTES: RYAN MASON (for Dembele, 69): 5 BEN DAVIES (for Rose, 82): 6 JOSH ONOMAH (for Alli, 90): 5 Aston Villa BRAD GUZAN: 7 CIARAN CLARK: 5 LEANDRO BACUNA: 5 SCOTT SINCLAIR: 6 GABBY AGBONLAHOR: 5 ASHLEY WESTWOOD: 6 JOLEON LESCOTT: 6 KIERAN RICHARDSON: 5 ALAN HUTTON: 6 CARLOS SANCHEZ: 5 JACK GREALISH: 7 SUBSTITUTES: JORDAN AYEW (for Westwood, 38): 7 RUDY GESTEDE (for Agbonlahor, 45): 6 CARLES GIL (for Grealish, 65): 7 STAR PLAYER Dele Alli: It was hardly a game for outstanding individual performances but Alli was dynamic with his runs and capped another impressive display with a well-taken goal on the stroke of half-time. MOMENT OF THE MATCH Ayew’s long-range strike came out of the blue for Villa in the 79th minute and set up a nervous finish at White Hart Lane. The young forward has struggled to settle since arriving at Villa Park in the summer but new boss Remi Garde will hope this goal can spark a better run of form for the 24-year-old. VIEW FROM THE BENCH Garde was watching on from the stands and he will have learned a great deal from his side’s defeat. Villa are struggling for goals and that showed, with neither Rudy Gestede nor Gabby Agbonlahor offering much threat before Ayew’s deflected second-half strike. Mauricio Pochettino would have liked a more comfortable win for Spurs, particularly with Anderlecht to come on Thursday in the Europa League before a visit to Arsenal on Sunday. As it was, Spurs were left hanging on before Harry Kane completed the win in injury time. MOAN OF THE MATCH Why was Ayew not starting? The forward looked bright when he came on and surely needs to be given more games, and confidence, under his new manager. WHO’S UP NEXT Tottenham v Anderlecht, November 5 (Europa League) Aston Villa v Manchester City, November 8 (Premier League) England international Alli continues to impress but has been urged to keep his feet on the ground by Spurs boss Mauricio Pochettino, whose side are now unbeaten in 10 league games. “When you have quality like he has, you need to push him and try to improve his game,” the Argentinian told Sky Sports 1. “I’m very pleased with him and the whole team. I think today we showed very good quality during some periods but always in football you need to kill the game and we suffered a bit in the last 10 minutes.” MacDonald hands the reins over to Garde on Tuesday and is confident the new man has enough talent at his disposal to get Villa out of trouble. “We actually came with a game-plan, but that went out of the window after two minutes,” he said. “Remi was late coming in with his flight and he just left it down to ourselves tonight. I’ll tell him he’s got something to work with.” Villa remain bottom of the table after their seventh straight Premier League defeat, and despite showing the fight for a battle against relegation they need a dramatic turn around after taking only four points from their first 11 games. Mousa Dembele fired Tottenham ahead after only three minutes and Dele Alli made it 2-0 on the stroke of half-time. Villa surprisingly pulled one back when Jordan Ayew’s 79th minute shot was deflected but a fine strike from Harry Kane in stoppage time made sure of the win for Spurs. Garde’s was a watching brief only with the match kicking off hours after he took charge, while Villa captain Micah Richards learned shortly before kick-off that he was suspended after admitting a misconduct charge from the Football Association relating to the loss against Swansea. Without their skipper, Villa started poorly. As if to highlight their many struggles, Spurs’ Mousa Dembele collected a third-minute pass from Danny Rose on the left wing before cutting inside to the penalty area, easing past Ciaran Clark – starting in Richards’ absence – and sending a left-footed shot through Brad Guzan’s legs. For a team so obviously bereft of confidence it seemed likely to be only the first of several goals that would soon follow, but after a flat period Villa impressed in their initial reaction, even if it came amid Spurs’ casual approach. The lively Scott Sinclair, who in unison with Jack Grealish can form the start of a promising attack, dribbled inside from the left wing before sending a powerful shot at Hugo Lloris which the goalkeeper routinely saved. It took until the 24th minute for Spurs to again threaten, this time when Harry Kane created space before his close-range shot was deflected by Alan Hutton and impressively tipped over by Guzan, and shortly before Dembele’s 25-yard strike comfortably cleared the crossbar. Spurs had relaxed amid the security provided by their early goal, but they again began to demonstrate their superior quality and in the first minute of first-half stoppage time the impressive Alli – in front of the watching Roy Hodgson – doubled their lead. Joleon Lescott’s loose header fell his way and the talented 19-year-old showed a maturity beyond his years to tee up his right-footed shot and find the bottom-left corner. Villa caretaker manager Kevin MacDonald responded at half-time by introducing Rudy Gestede but the striker continued his Premier League struggles and was never likely to inspire a comeback.

Darwin’s Linux: Did Evolution Produce a Computer?

first_imgHow is a cell like a computer?  Some Yale scientists asked that question, and embarked on a project to compare the genome of a lowly bacterium to a computer’s operating system.1.  Their work was published in PNAS.2  As with most analogies, some things were found to be similar, and some different – but in the end, these two entities might be more similar overall in important respects.    The interdisciplinary team, composed of members of the Computer Science department and the Molecular Biophysics and Biochemistry department, calls itself the Program in Computational Biology and Bioinformatics.  Recognizing that “The genome has often been called the operating system (OS) for a living organism,” they decided to explore the analogy.  For subjects, they took the E. coli bacterium, one of the best-studied prokaryotic cells, and Linux, a popular Unix-based operating system.  The abstract reveals the basic findings, but there’s more under the hood:To apply our firsthand knowledge of the architecture of software systems to understand cellular design principles, we present a comparison between the transcriptional regulatory network of a well-studied bacterium (Escherichia coli) and the call graph of a canonical OS (Linux) in terms of topology and evolution.  We show that both networks have a fundamentally hierarchical layout, but there is a key difference: The transcriptional regulatory network possesses a few global regulators at the top and many targets at the bottom; conversely, the call graph has many regulators controlling a small set of generic functions.  This top-heavy organization leads to highly overlapping functional modules in the call graph, in contrast to the relatively independent modules in the regulatory network.  We further develop a way to measure evolutionary rates comparably between the two networks and explain this difference in terms of network evolution.  The process of biological evolution via random mutation and subsequent selection tightly constrains the evolution of regulatory network hubs.  The call graph, however, exhibits rapid evolution of its highly connected generic components, made possible by designers’ continual fine-tuning.  These findings stem from the design principles of the two systems: robustness for biological systems and cost effectiveness (reuse) for software systems.We see they have already concocted a curious mixture of designer language and evolution language.  The design language continues in the heart of the paper.  Design principles, optimization, constraints, frameworks, interconnections, information processing – these engineering phrases are ubiquitous.  Consider this paragraph that starts with “master control plan.”  They applied it not to Linux but to the cell, which is found to have many similarities to the master control plan of the computer operating system:The master control plan of a cell is its transcriptional regulatory network.  The transcriptional regulatory network coordinates gene expression in response to environmental and intracellular signals, resulting in the execution of cellular processes such as cell divisions and metabolism.  Understanding how cellular control processes are orchestrated by transcription factors (TFs) is a fundamental objective of systems biology, and therefore a great deal of effort has been focused on understanding the structure and evolution of transcriptional regulatory networks.  Analogous to the transcriptional regulatory network in a cell, a computer OS consists of thousands of functions organized into a so-called call graph, which is a directed network whose nodes are functions with directed edges leading from a function to each other function it calls.  Whereas the genome-wide transcriptional regulatory network and the call graph are static representations of all possible regulatory relationships and calls, both transcription regulation and function activation are dynamic.  Different sets of transcription factors and target genes forming so-called functional modules are activated at different times and in response to different environmental conditions.  In the same way, complex OSs are organized into modules consisting of functions that are executed for various tasks.And yet, on the other hand, the team felt that both the cell and Linux vary under processes of evolution:Like biological systems, software systems such as a computer operating system (OS) are adaptive systems undergoing evolution.  Whereas the evolution of biological systems is subject to natural selection, the evolution of software systems is under the constraints of hardware architecture and customer requirements.  Since the pioneering work of Lehman, the evolutionary pressure on software has been studied among engineers.  Interestingly enough, biological and software systems both execute information processing tasks.  Whereas biological information processing is mediated by complex interactions between genes, proteins, and various small molecules, software systems exhibit a comparable level of complexity in the interconnections between functions.  Understanding the structure and evolution of their underlying networks sheds light on the design principles of both natural and man-made information processing systems.These paragraphs provide a flavor of the basic assumptions of the paper: that cells and OSs are analogous in their design principles and in their evolution.  So what did they find?  Their most eye-catching chart shows that Linux is top-heavy with master regulators and middle management functions, whereas a cell’s transcription network is bottom-heavy with workhorse proteins and few top management functions.  The illustration has been reproduced in an article on PhysOrg with the interesting headline, “Scientists Explain Why Computers Crash But We Don’t.”    A table in the Discussion section of the paper summarizes the main similarities and differences they found.  Here are some noteworthy examples:Cells are constrained by the environment; Linux by the hardware and customer needs.Cells evolve by natural selection; Linux evolves by designers’ fine-tuning.Cells have a pyramid-shaped hierarchy; Linux is top-heavy.Cells don’t reuse genes much, but Linux reuses function calls often.Cells don’t allow much overlap between modules, but Linux does.Cells have many specialized workhorses; Linux concentrates on generic functions.Cell evolutionary rates are mostly conservative; in Linux, they are conservative to adaptive.Cell design principles are bottom up; in Linux, they are top down.Cells are optimized for robustness; Linux is optimized for cost effectiveness.The differences seem to be winning.  Cells and Operating Systems have different constraints; therefore, they have different design principles and optimization.  But not so fast; the team only studied a very lowly bacterium.  What would happen if they expanded their study upward into the complex world of eukaryotes?  Here’s how the paper ended:Reuse is extremely common in designing man-made systems.  For biological systems, to what extent they reuse their repertoires and by what means sustain robustness at the same time are questions of much interest.  It was recently proposed that the repertoire of enzymes could be viewed as the toolbox of an organism.  As the genome of an organism grows larger, it can reuse its tools more often and thus require fewer and fewer new tools for novel metabolic tasks.  In other words, the number of enzymes grows slower than the number of transcription factors when the size of the genome increases.  Previous studies have made the related finding that as one moves towards more complex organisms, the transcriptional regulatory network has an increasingly top-heavy structure with a relatively narrow base.  Thus, it may be that further analysis will demonstrate the increasing resemblance of more complex eukaryotic regulatory networks to the structure of the Linux call graph.1.  An operating system is the foundational software on a computer that runs applications.  A useful analogy is the management company for a convention center.  It doesn’t run conventions itself, but it knows the hardware (exhibit halls, restrooms, lights, water, power, catering) and has the personnel to operate the facilities so that a visiting company (application) can run their convention at the center.2.  Yan, Fang, Bhardwaj, Alexander, and Gerstein, “Comparing genomes to computer operating systems in terms of the topology and evolution of their regulatory control networks,” Proceedings of the National Academy of Sciences published online before print May 3, 2010, doi: 10.1073/pnas.0914771107.This is a really interesting paper, because it illustrates the intellectual schizophrenia of the modern Darwinist in the information age.  It might be analogous to a post-Stalin-era communist ideologue trying to recast Marxist-Leninist theory for the late 1980s, when the failures of collectivism have long been painfully apparent to everyone except the party faithful.  With a half-hearted smile, he says, “So we see, that capitalism does appear to work in certain environments under different constraints; in fact, it may well turn out to be the final stage of the proletarian revolution.”  Well, for crying out loud, then, why not save a step, and skip over the gulags to the promised land of freedom!    You notice that the old Darwin Party natural-selection ideology was everywhere assumed, not demonstrated.  The analogy of natural selection to “customer requirements and designers’ fine-tuning” is strained to put it charitably; to put it realistically, it is hilariously funny.  The authors nowhere demonstrated that robustness is a less worthy design goal than cost-effectiveness.  For a cell cast into a dynamic world, needing to survive, what design goal could be more important than robustness?  Linux lives at predictable temperatures in nice, comfortable office spaces.  Its designers have to design for paying customers.  As a result, “the operating system is more vulnerable to breakdowns because even simple updates to a generic routine can be very disruptive,” PhysOrg admitted.  Bacteria have to live out in nature.  A cost-effective E. coli is a dead E. coli.  The designer did a pretty good job to make those critters survive all kinds of catastrophes on this planet.  The PhysOrg article simply swept this difference into the evolutionary storytelling motor mouth, mumbling of the bacterial design, that “over billions of years of evolution, such an organization has proven robust.”  That would be like our communist spin doctor alleging that the success of capitalism proves the truth of Marxist doctrine.    A simple bacterial genome shows incredibly successful design for robustness when compared to a computer operating system, albeit at the cost of low reuse of modules.  But then the authors admitted the possibility that eukaryotes might well have achieved both robustness and modular reusability.  That would make the comparison to artificial operating systems too close to call.  If we know that Linux did not evolve by mutations and natural selection, then it is a pretty good bet that giraffes and bats and whales and humans did not, either.  That should be enough to get Phillip Johnson’s stirring speech, “Mr. Darwin, Tear down this wall!” to stimulate a groundswell of discontent with the outmoded regime.  May it lead to a sudden and surprising demise of its icons, and a new birth of academic freedom.(Visited 52 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

Shocking Facts About Electric Life

first_imgWired fish:  Two more electric fish species have been found in the Amazon basin, but they appear to be wired differently.  One is biphasic or “AC” like most others, but another is monophasic like “DC”.  The article on Science Daily looked for evolutionary reasons why this might be so, but the interesting thing is that “these weakly fishes produce pulses of only a few hundred millivolts from an organ under the body that extends out onto a filamentous tail.”  Too weak to stun prey like the jolts from the famous electric eel, the pulses are read by other members of the species, and by the opposite sex, for communication.  The fish also use them “to ‘electrolocate’ through their complex aquatic environment at night.”  As for evolution, the two fish are so similar as to be classified as the same species except for the differences in electrical phase of their signals.So many ways of receiving input from the world: touch, sight, sound, smell, taste, and now electricity.  The living world is a marvel of interactions between organism and environment.  Each sense is exquisitely designed and useful to the organism.  Elegant systems are not the result of blind, unguided processes.  We believe that viewing them as designed systems would energize research, both to seek understanding of superior design, and to desire to imitate it for improved engineering.  The real science stopper is to assume, “Oh, it just evolved.  It evolved because it evolved”– a soporific response possessing a dormitive virtue   (cartoon and 5/25/05 commentary) (Visited 38 times, 1 visits today)FacebookTwitterPinterestSave分享0 Talk about power plants: did you know plants use electricity?  Some fish, also, can navigate or stun their prey using electrical organs.Power plants:  Nature discussed how electrical signals are propagated in plants.  The Venus flytrip and “sensitive plant” come to mind as spectacular examples of non-muscular leaf movement triggered by electricity, but there’s more:The mammalian nervous system can relay electrical signals at speeds approaching 100 metres per second. Plants live at a slower pace. Although they lack a nervous system, some plants, such as the mimosa (Mimosa pudica) and the Venus flytrap (Dionaea muscipula), use electrical signals to trigger rapid leaf movements. Signal propagation in these plants occurs at a rate of 3 centimetres per second — comparable to that observed in the nervous system of mussels. On page 422 of this issue, Mousavi et al. address the fascinating yet elusive issue of how plants generate and propagate electrical signals. The authors identify two glutamate-receptor-like proteins as crucial components in the induction of an electrical wave that is initiated by leaf wounding and that spreads to neighbouring organs, prompting them to mount defence responses to a potential herbivore attack.Who would have thought that cutting a leaf would send an electrical alarm?  Experiments on common thale cress showed no response when a larva walked on a leaf, but an electrical signal spreading at 9 cm per minute when eaten.  “The relay of the electrical signal was most efficient for leaves directly above or below the wounded leaf,” the article said.  “These leaves are well connected by the plant vasculature, which conducts water and organic compounds, and is a good candidate for the transmission of signals over long distances.”  Receipt of the signal turned on gene expression for defense compounds.  “These fascinating observations clearly demonstrate that electrical signal generation and propagation have a crucial role in the initiation of defence responses at remote sites upon herbivore attack.”The authors of the original paper did not discuss evolution, other than to speculate that “a deeply conserved function for these genes might be to link damage perception to distal protective responses.”  If so, this function must have “existed before the divergence of animals and plants.”last_img read more

ChaCha Beats Google and Yahoo in Mobile Voice Search Tests

Mobile analyst firm MSearchGroove has just published the results of a series of tests which show that the mobile search service ChaCha beat out two other voice-enabled search applications on the iPhone when it comes to search query accuracy. [Update, Ed: a commenter points out that the report was actually sponsored by ChaCha] To test this, the researchers used Google’s own mobile application and Vlingo for iPhone, an app that lets you search both Google or Yahoo. Oddly, they ignored Yahoo’s mobile app, which also has voice search built in. The results of their study aren’t entirely shocking: if you want to be understood, ask a human, not a computer.The Mobile Search TestsChaCha’s mobile search service can be accessed both by SMS and by calling a toll-free 1-800 number. Since these tests focused on voice search, the phone-in method was used. When using ChaCha, the service identified the queries accurately in 94.4% of the cases and delivered accurate search results 88.9% of the time. Vlingo, which the researchers used to test Yahoo search, only interpreted queries correctly in 72.2% of the cases and delivered accurate results 27.8% of the time. Google, surprisingly, fared worst of all. Their mobile application only understood spoken queries in 16.7% of tests and delivered accurate results 22.2% of the time. To test the applications, the researchers conducted two rounds of tests using both keyword search and natural language queries where they asked questions using sentences. The queries represented a cross-section of typical mobile searches in categories like navigation, directions, local search, general information, social search, and long-tail search.It’s not all that surprising to find that ChaCha outperformed the other voice-enabled applications – after all, they have real, live humans on the other end of the line to interpret the spoken questions. What is surprising, though, is how wide the gap is in between the human-powered search and the speech recognition apps, especially when contrasting ChaCha with Google.Did Google Just Get Beaten at Search? When you think of search, you tend to think “Google.” When you use Google, there’s a certain expectation that your queries will be interpreted accurately and your results will be relevant. What these tests show, however, is that when it comes to the mobile platform, all bets are off. Not only was Google outperformed by a mobile application whose name few mainstream users have probably heard of (Vlingo), they were also outperformed by a crowdsourced workforce who answer ChaCha queries in their spare time. Could this mean that mobile search is an area – perhaps the only area – where a competitor could actually get a foothold and steal away a bit of Google’s market share? Well, not so fast. Google could still dominate on mobile thanks to brand recognition alone. Mainstream users aren’t going to seek out new alternatives to search, even if they’re better. That’s precisely why companies like Microsoft have to spend millions of dollars on advertising campaigns just to gain a percentage point or two of search market share. Then there’s the fact that tests which compare human-interpreted queries to machine-interpreted ones seem a little unfair. We all know that people can still understand each other much better than computers can. (Well, for now at least). ChaCha wins this round, but only because this was never a fair fight to begin with. Speech recognition and natural language processing are technologies still in their infancy. But if we know Google, they’re coding away right now to improve them as we speak.last_img read more
