Mouseless, the ‘invisible’ computer mouse (w/ Video) (PhysOrg.com) — When you hear the name Amenbo, what do you think of? Is it a computer mouse? Apparently the fine folks over at Double Research & Development Company did think of a mouse because they names their newest mouse the Amenbo. Of course, anything with a name this funky cannot be ordinary, it has to be unique and the Amenbo definitely is unique.

These pads are then used to determine the pressure and movements of each of those fingers and send that input into the PC. Each of these pads is then connected to a wire mesh that allows them to work in concert should they need to, or the fingers can work individually by adjusting the amount of pressure that is placed onto them. The mesh is able to stretch to accommodate the size of the user’s hand. With this system the mouse can then be used with a range of software applications that can work with complete hand recognition.Potential applications for the Amenbo including working with 3D CAD data. The system usually requires a user to operate both a 3D mouse and a standard mouse, one in each hand, which can be cumbersome and requires an adjustment period in order to gain proficiency. The Amenbo would be able to replace the two-mouse system. No word on the pricing or availability of this new style of mouse as of yet.

More information: The genome sequence of Atlantic cod reveals a unique immune system, Nature (2011) doi:10.1038/nature10342AbstractAtlantic cod (Gadus morhua) is a large, cold-adapted teleost that sustains long-standing commercial fisheries and incipient aquaculture. Here we present the genome sequence of Atlantic cod, showing evidence for complex thermal adaptations in its haemoglobin gene cluster and an unusual immune architecture compared to other sequenced vertebrates. The genome assembly was obtained exclusively by 454 sequencing of shotgun and paired-end libraries, and automated annotation identified 22,154 genes. The major histocompatibility complex (MHC) II is a conserved feature of the adaptive immune system of jawed vertebrates, but we show that Atlantic cod has lost the genes for MHC II, CD4 and invariant chain (Ii) that are essential for the function of this pathway. Nevertheless, Atlantic cod is not exceptionally susceptible to disease under natural conditions5. We find a highly expanded number of MHC I genes and a unique composition of its Toll-like receptor (TLR) families. This indicates how the Atlantic cod immune system has evolved compensatory mechanisms in both adaptive and innate immunity in the absence of MHC II. These observations affect fundamental assumptions about the evolution of the adaptive immune system and its components in vertebrates.

The missing gene is one that codes for proteins called MHC II, CD4, and invariant chain. These proteins that reside on the outside of cells are responsible for noticing when bacteria or viruses land and then for calling CD4+ T cells to alert B cells which then start to crank out antibodies. The team has published its results in Nature. The Atlantic Cod Gadus morhua, is one of the more popular fish caught for consumption in the waters of the Atlantic, from North America to Europe, though it’s viability as a food source has come into question due to the collapse of several stocks in the 1990’s and their inability to recover. Subsequently, attempts have been made to create cod farms, but have met with mixed results due to the fish’s susceptibility to such infections as the bacterium Francisella noatunensis. It was this problem that led the Oslo team to sequence the cod’s genome in hopes of uncovering a means for creating a vaccine that would allow for more successful operations. Unfortunately, it appears that due to the cod’s missing genes, the traditional approach to creating a vaccine won’t work.To sequence the cod genome, the team used the Roche 454 platform and then aligned the result with that of the stickleback, a fish closely related to the cod that has already been sequenced. In so doing they found, in addition to the missing MHC II, new hemoglobin genes that are believed to help the cod survive in the very cold water in which it lives. The team says that the cod makes up for the MCH II deficiency by having more genes than other vertebrates, and also theorizes that the cod may also do more with MCH I (which normally specialize in finding intruders within cells) than other vertebrates.The discovery of the cod’s unique immune system has caused excitement in the immunology field because it opens the door to new ideas and ways of looking at how the immune system works and how such knowledge might be applied in developing better vaccines in cod farming; something that could become more important as natural fish populations decline.

More information: Emission pathways consistent with a 2 °C global temperature limit, Nature Climate Change (2011) doi:10.1038/nclimate1258In recent years, international climate policy has increasingly focused on limiting temperature rise, as opposed to achieving greenhouse-gas-concentration-related objectives. The agreements reached at the United Nations Framework Convention on Climate Change conference in Cancun in 2010 recognize that countries should take urgent action to limit the increase in global average temperature to less than 2 °C relative to pre-industrial levels. If this is to be achieved, policymakers need robust information about the amounts of future greenhouse-gas emissions that are consistent with such temperature limits. This, in turn, requires an understanding of both the technical and economic implications of reducing emissions and the processes that link emissions to temperature. Here we consider both of these aspects by reanalysing a large set of published emission scenarios from integrated assessment models in a risk-based climate modelling framework. We find that in the set of scenarios with a ‘likely’ (greater than 66%) chance of staying below 2 °C, emissions peak between 2010 and 2020 and fall to a median level of 44 Gt of CO2 equivalent in 2020 (compared with estimated median emissions across the scenario set of 48 Gt of CO2 equivalent in 2010). Our analysis confirms that if the mechanisms needed to enable an early peak in global emissions followed by steep reductions are not put in place, there is a significant risk that the 2 °C target will not be achieved. The group, comprised of European, Japanese, Chinese and Australian scientists and researchers, and led by Joeri Rogelj, has been studying the published literature comparing current and projected rates of carbon emissions and has correlated those numbers with an expected rise in global temperatures as a result. They then set up scenarios (using modeling developed by Malte Meinshausen) where they tried to predict likely outcomes (defined as a 66% or better chance) of average global temperatures peaking at or below the 2 degree goal given defined reductions in carbon emissions within certain timeframes. In so doing they found that in order to meet the 2 degree ceiling goal, carbon emissions would have to peak sometime between now and 2020, and then would need to immediately fall thereafter, at least to a median level of 44 Gt (gigatonnes or billion tonnes) of CO2 equivalent in 2020. And it doesn’t stop there, levels would have to continue falling, to around 20 Gt by 2050.And while the group says it believes reaching these goals is possible, it’s clear that drastic action will need to be taken as last year’s estimates of carbon emissions was around 48 Gt, and based on the way things are going presently, many experts fear carbon emissions will increase to 56 Gt by 2020. As part of presenting their findings, the group laid out scenarios that they believe if followed, would result in meeting the 2 degree ceiling. These would generally include replacing carbon emitters (mainly coal) with energy producers that are based on solar photovoltaic, wind and biomass technologies.Also of concern are increases in regional temperatures, which are uneven due to the Earth being covered mostly in cold water. As the Earth warms up, temperatures over landmasses heat up far more quickly than they do over the oceans, thus, temperatures for some places such as parts of Africa, the Arctic, Canada and Eurasia, which are already seeing spikes, are likely to continue to do so. Some experts warn these areas might see the 2 degree threshold in just ten or twenty years.The next round of talks is scheduled to begin next month in Durban, South Africa, and some members of the research team are already speaking out, suggesting that unless immediate action is taken, the opportunity of meeting the 2 degree ceiling could slip away.

High-voltage power lines are a source of UV light due to a build-up of ionized gas—when it suddenly dissipates, flashes of UV light are emitted. The larger the buildup and release the larger the flash. Power companies try to minimize such build-ups as they indicate a loss of power, or inefficiencies in a line—they use special goggles to find and repair large problem areas. Normally people only become aware of the flashes when they hear cracking or popping noises, particularly in winter.Many animals (approximately 35 known species) on the other hand, are able to see UV light in all its glory, and most of them appear to find it alarming in power cables. It tends to cause fragmenting of species, problems with grazing and a reduction in populations. Prior to this study, it was thought that perhaps animals avoided power line paths due to the openness of the terrain created when trees are removed. In this new effort, the researchers note that one species of animal, reindeer, appear to be particularly sensitive to the UV light. Not only can they see UV light (normally used to help find plants buried beneath snow) but their eyes are particularly sensitive to it because of the long dark winters. They see the UV light as random flashes lighting up the area (made worse when it bounces off snow and ice) accompanied by popping noises. It’s enough to cause the animals to stay away from lines and structures—they won’t walk under them, leaving them cut off from land on the other side. The problem has caused herders in Norway to be at odds with power companies over construction of new lines.Scientists have noted a tendency for animals to avoid power lines in places all over the globe, but were confused as to why—power lines are high enough to avoid contact and few people are around once they are put up. Some have suggested it was due to clear cutting vegetation, but animals in areas where there is little vegetation to begin with (such as reindeer habitat) have avoided them as well. More studies will have to be done to conclusively prove that it’s UV light, but at this point, it appears likely. © 2014 Phys.org This document is subject to copyright.

And, the discovery of a new subatomic particle is shedding light on the fundamental force of nature—researchers with the University of Warwick found the particle (dubbed Ds3*(2860)) using the Large Hadron Collider. They believe it will “transform our understanding” of the fundamental force of nature that binds the nuclei of atoms.In applied applications, a team of engineers at Washington University has come up with a design for a fusion reactor that could be cheaper than using coal—they claim scaling it to the size of a coal plant would make the plant economical. Meanwhile another team of researchers has come to the conclusion that there are only four unique city topologies—they used data from OpenStreetMap and mathematics to come to this conclusion.Also, some good news came from a combined team of researchers looking into the mechanism that underlies diabetes—they’ve actually discovered a “good” fat that fights diabetes—a new class of molecules that appears to protect both mice and humans from the onset of the debilitating disease. And in an interesting bit of research, a team of scientists has traced the evolutionary history of Arctic bacteria and in so doing, have found a long evolution of toxic mercury resistance—a finding that could have implications on research that involves looking for life on other planets.And finally, researchers at QIMR Berghofer Medical Research Institute announced that they’ve found a cancer drug that destroys tumors in pre-clinical trials—it’s still preliminary work, but the implications are staggering—imagine if doctors could actually destroy cancer tumors with a simple drug made from the seeds of a rainforest plant. It was another banner week for physics as the Nobel Prize in physics was announced—Isamu Akasaki, Hiroshi Amano and Shuji Nakamura shared the prize for their work in inventing a new kind of LED. Also, mysteriously, a team of researchers working in Australia found evidence that there is just half as much dark matter in the Milky Way Galaxy as scientists have believed. © 2014 Phys.org Explore further
A thing of beauty is a joy forever’ is a statement that is especially true for Kashmir. Gallerie Ganesha presents a solo exhibition titled Paradise Regained by Alok Uniyal. Inspired by Kashmir, the show has 20 paintings in acrylics on canvas, each panoramic work defining the state’s breathtaking natural beauty, its culture and eternal romance.This is not the first time, however, that the Uniyal has brought a city’s diverse landscape alive on his canvas. In previous art outings, he has created series of paintings around Kolkata (2007), Goa (2008) and even Delhi (2010), and Kashmir is another series. Also Read – ‘Playing Jojo was emotionally exhausting”I always visit a place and that inspires me to paint my impressions of what I observe. I travelled to Kashmir last year in October, and despite the fact that the state has faced such turmoil, somehow it still retains its mesmerising natural beauty and charm. Why would I then want to paint harsh realities that we read about anyway in papers everyday,’ says Uniyal. The works also reflect elements of Indian traditional art – like miniature paintings and terracotta art – especially as Uniyal belongs to Uttaranchal.’
What has the journey of Ajay Devgn Films been like so far?Ajay Devgn (AD): It’s been very good. We co-produced our first film in 1996 – Pyaar Toh Hona Hi Tha. Then we made an array of films like Hindustan Ki Kasam, Dil Kya Kare, Raju Chacha, All The Best, Bol Bachchan and Son Of Sardaar. So it’s been fabulous, touch wood. Except for Raju Chacha, where I got very ambitious. The film didn’t do badly but the budgets were too high. We were talking of a Rs 30-crore budget 13 years ago. Also Read – ‘Playing Jojo was emotionally exhausting’I had built a set and we were doing animation for the first time but I was happy that it was us who introduced CG in India. Apart from this film, all our other films have done well and made money. My intention is not to make just films but to only make good films. Otherwise, I would be making ten films a year! The idea is to make good films and to get the right scripts. In fact, currently we are working on four or five scripts, which will go on the floors in a few months. As always, they’re progressive cinema but also entertaining. Also Read – Leslie doing new comedy special with NetflixYou were the first actor to get into production.AD: (Cuts in) Yeah, I think so! Kuch scripts aisi hoti hain jinko padhke lagta hai ki yeh aapko bannani chahiye. And you always want to experiment with it. Like Dil Kya Kare was one of those films. It did very well overseas. There were some scripts that I really wanted to make and Raju Chacha was an ambitious one, where I wanted animation of that level. And which I didn’t think any other producer could have thought of at that level for me and could actually do it. That’s why I thought I might as well do it! So, it’s all about belief in a film and if you rope in someone else, he or she would want to chip in with their ideas. You may want to make a particular film your way and the other person may not be on the same page. Some people approach you with their vision and if you believe in their vision, you team up with them. At the same time, when you come across a film and you think only you can justify it, you go with your gut feel.You have a very lean, mean organisation.AD: I believe that few people can do their job but it is very important that they know their job. Today, when we meet with corporates, Tees log aakar baith jaate hain, ussmein se 15 log kya kar rahe hain hamein pata hi nahi hota. Meeting kis baat ki ho rahi hai pata nahi hota. But that’s how they work and this is how we work. We know what we’re doing.There are no chairs here, there are faces. This is the basic difference between a corporate studio and a production house. I don’t mean to criticise corporatisation but too many cooks can spoil the broth. A crowd only leads to confusion. But our company knows who’s doing what, their respective strengths and weaknesses, and each one of us gives our best.All the films you have produced feature you as the lead actor in them. Do you see that changing?AD: Yes, that’s changing! Like I said, we are working on four to five films right now. Out of them, only two of them feature me in the cast.Apart from being the first to get into production and distribution, you’ve always believed in budding talent and have worked with first-time directors.AD: (Smiles) Anees Bazmi, Rohit Shetty and Bunty (Milan Luthria) started with us. When I worked with these guys, they were all new directors and now they are very big directors. I am going to do the same in future too.Looking back… What made you sign Prakash Jha for Dil Kya Kare although he was in a lull phase?AD: I heard the script of Dil Kya Kare and, yes, Prakashji was going through a lull phase. I told him I loved the script a lot. It was a unique script at the time and I wanted to promote films like that. So I asked him if he would let me produce it. He agreed immediately. Basically, I am the only commercial actor who started dabbling with films like Thakshak or Zakhm because I wanted to balance things. I have learnt a lot from Bhatt saab (Mahesh Bhatt), Prakashji (Prakash Jha) and Govindji (Govind Nihalani). My growth as a performer has come from their abilities.After Dil Kya Kare, you worked with Prakash Jha again, on Gangaajal, which was like Jha-sir’s revival in commercial cinema.AD: Because I believe in that kind of cinema. I feel Prakashji found a great balance between telling a story, engaging the audience and saying something more. You don’t expect films like these to do extraordinary business because they are also social-oriented. Somewhere, you should do films like these as well as long as they are not disasters. They are like oxygen to acting and the other films are oxygen to stardom.You have stood by directors, regardless of their track record. Did you do that to create goodwill?AD: It is not about goodwill! Rohit and Bunty started their careers with me as assistants. We shared a great rapport and I promised them that I would do a film with them whenever they were ready. And that’s what I did.The fact that your banner carries your name, do you think it becomes a liability sometimes given your stature as a star?AD: One has to be very careful with what you are associating with. Now, I can’t name the film but I wouldn’t want to be associated with a vulgar film.What type of films does Ajay Devgn Films stand for?AD: Commercial, good… everything! Where people like watching the film and where you can make something that is sensitive and nice, and which is still commercial.One final question – how does Ajay, the actor, help Ajay Devgn, the producer, and vice-versa?AD: I make better cinema that way. Ajay, as an actor, has his upside also for a production house. In terms of a producer helping the actor, you realise that there’s a certain sincerity when you think ki yaar agar you’ll leave it and not do a good job then kitna nuksaan ho jayega. As a child, I used to go on the sets with my dad. I won’t name the actor but woh aaram se 2:30 pm tak aate the aur sab dhoop main baithe rehte thhe. Tab namake-up vans hoti thi na umbrellas hote thhe. And that actor would come giving gaalis and throwing his weight around. And the entire unit would bad-mouth him behind his back. I never forgot that. That’s when I decided I would never arrive late for a shoot. Warna log mujhe bhi gaali denge.– With special arrangement with Box Office India

Indian abstract artists drew on a range of influences in their work – Western abstract art, in particular the works of artists such as Klee, Rothko, Pollock or Calder, East-Asian influences, and significantly, a range of traditional, tribal, folk and tantric art – for their techniques, themes and approaches. Additionally, it also brings together lesser-known abstract works of artists that are known for their fidelity to figurative or representative art – these feature artists such as MF Husain, Somnath Hore, Dharamnarayan Dasgupta, Benode Behari Mukherjee, Sunil Das and Rabin Mondal – their abstract works are a delight to behold and add significantly to our understanding of Indian modernism’s journey.An over 400-page, substantial volume of art scholarship has accompany this significant exhibition, featuring colour plates of artworks and scholarship by leading art historians examining the journey of the abstract in Indian art.When: On till 30 SeptemberWhere: Delhi Art Gallery, 11 Hauz Khas Village
Kolkata: A major fire broke out at a storeroom packed with garments off Foreshore Road in Howrah at around 12.30 am on Sunday. Ten fire tenders were pressed into service to douse the flames. Firefighters took around six long hours to douse the flames.Locals saw smoke billowing out of the huge storeroom situated close to the bank of river Hooghly and informed the state Fire and Emergency Services department.Locals initiated the work to douse the flames. Fire fighters took the minimum time to reach the spot and initiated the work properly to extinguish the fire. An officer of the state Fire and Emergency Services department said the exact reason behind the fire could not be ascertained yet. But they are suspecting electric short circuit led to the incident. Also Read – Heavy rain hits traffic, flightsThe officer further said the storeroom is situated close to the river bank. As a result, a gush of wind from the river side prompted the fire to spread fast and it spread to the entire go down within a short span of time.It also made the task difficult for the firefighters. The fire fighters took necessary steps and restricted the flames from spreading to the adjacent structures. They worked the entire night and doused the flames by 6 am in morning. Locals, who witnessed the incident, said the situation turned worse when the roof over a portion of the godown collapsed. Also Read – Speeding Jaguar crashes into Merc, 2 B’deshi bystanders killedThe fire fighters had managed to enter the storeroom after bringing the situation under control and they searched inside the storeroom to become sure that there was no one inside. Police confirmed that there was no one inside the storeroom as it was a Sunday. The entire godown was gutted but the total extend of damage is yet to be ascertained. The fire department officials are trying to ascertain whether there was proper fire fighting measures in the storeroom.
