This configuration would then be used in cities where the robots would be deployed. The challenge is to have the robots work cooperatively with the senses around them and also with people. Autonomous navigation is another key factor for the robots. It’s important that the robots know where they are going and what may seem easy for us is very complex for the robots. The robots are equipped with an engine that is powered by a lithium-battery which permits them to run silently. The robots are also equipped with special sensors that can monitor air pollutants such as nitrogen oxides, ozone, benzene, sulfur oxides, CO2, CO and air temperature.DustCart is still in the prototype stage and does not have the kind of rapid response time that would make them effective on crowded streets. One day however these robots may become tourist guides or even help the elderly. Via: GlobalPost© 2009 PhysOrg.com (PhysOrg.com) — In the city of Peccioli in the Tuscany region of Italy a robot called DustCart has been zipping through the streets. This is part of a $3.9 million research program called DustBot that aims on collecting trash on demand. DustCart is designed to go from door-to-door collecting waste on demand. Waste is deposited into the robot by opening the trash draw using a touch screen display. The draw is then closed and the type of trash is selected using the touch screen. DustCart would then take the rubbish to a central collection point. This document is subject to copyright.

Journal information: Proceedings of the National Academy of Sciences Violent passions — jealous cleaner shrimp murder their rivals For years scientists have speculated that some ocean bacteria may glow to encourage others to eat them, but till now, no one had actually tested the theory. Zarubin and her colleagues thought it was time.As a means of proof, the team put a bag of water with normal Photobacterium leiognathi bacteria in it into a tank of water that held shrimp and other microbes. At the other end of the tank they put in another bag of the same kind of bacteria that had been genetically altered to prevent their being able to glow. The team found that the shrimp and other organisms gathered around the glowing bag, but not around the dark one.After that, they allowed a group of shrimp to swim around in water with the glowing bacteria in it, and found that after just a few hours, the shrimp’s bellies soon glowed with bacteria as well. Play Apogon annularis detects and efﬁciently consumes glowing Artemia in the dark. These Artemia became glowing by contacting and ingesting bioluminescent bacteria. Infrared light was used to illuminate the ﬂume for video recording. The lower part of the image (below the dark bar) shows the ﬂume’s working section as viewed from the side. The upper part shows the working section as viewed from above, through a 45° inclined mirror. Video: PNAS, doi: 10.1073/pnas.1116683109 Then, lastly, the shrimp that had glowing bellies were put into a flume alongside shrimp that had not eaten the glowing bacteria and all were sent past a quantity of shrimp eating fish. There it was observed that the fish ate only the shrimp that had glowing bellies. Afterwards, the team tested the feces from the fish and found that the glowing bacteria had come though the digestive process unscathed. And because fish, being fish tended to swim around, the bacteria had been transported to a new locale.From these simple experiments it appears clear that the bioluminescent abilities of the ocean bacteria tested help it to move more easily around in the ocean – using other organisms as a transport vehicle. In so doing the bacteria not only get a free ride, but get a meal along the way as they feast on other material inside the bellies of those that have eaten them.

One of the most commonly cited explanations, proposed more than 30 y ago, is that bioluminescence augments the propagation and dispersal of bacteria by attracting fish to consume the luminous material. This hypothesis, based mostly on the prevalence of luminous bacteria in fish guts, has not been tested experimentally. Here we show that zooplankton that contacts and feeds on the luminescent bacterium Photobacterium leiognathi starts to glow, and demonstrate by video recordings that glowing individuals are highly vulnerable to predation by nocturnal fish. Glowing bacteria thereby are transferred to the nutritious guts of fish and zooplankton, where they survive digestion and gain effective means for growth and dispersal. Using bioluminescence as bait appears to be highly beneficial for marine bacteria, especially in food-deprived environments of the deep sea.

(PhysOrg.com) — In most situations in the wild, animals develop abilities to help them avoid being eaten. The chameleon, for example, can change its color to avoid being seen by predators. What’s less usual, are animals or organisms that develop abilities that do the opposite, i.e. develop traits that encourage predators to eat them. But that’s just what certain ocean bacteria appear to do. Margarita Zarubin, a marine science grad student in Israel, and her colleagues have shown, as they report in their paper published in the Proceedings of the National Academy of Sciences, that a certain type of bioluminescent bacteria glow to attract the attention of other organisms, so as to be eaten; and they do so as a means of assisted dispersal.

(Phys.org) —Three high-schoolers from Cork County Ireland have won the top prize at this year’s Google Science Fair for their project that demonstrates a way to germinate seeds faster using bacteria as a seed treatment. Sophie Healy-Thow, Émer Hickey, and Ciara Judge won the Grand Prize by developing a way to increase crop yields in food scarce countries. After discovering nodules growing on pea plants in a family garden, which turned out to be the result of a reaction by the plant to bacteria in the soil, the teens began an investigation. They learned that the presence of certain bacteria can instill a sort of fear in a plant, causing it to speed up germination, so as to avoid being overtaken. They wondered what would happen if seeds were treated with a bacteria laden liquid before planting. To find out, they planted a garden with several different types of plants, some with treated seeds, others without, then tended the garden to see what impact the treatment would have.The group found that all of the treated seeds sprouted on average 50 percent faster than those that were left untreated, which, the team reports led to an increase in harvest amounts of some of the oats by as much as 70 percent.Speeding up germination means bacteria and other pests, such as insects, have less time to wreak havoc on new plants, which in the end results in more food being produced.The next step for the team (they’ve already applied for a patent) is to refine their process—to grow the bacteria (in soil), to harvest it and then to bottle and sell it. They may find that path easier than they thought as officials with the European Commission (the executive body of the European Union) have expressed interest in helping them develop their idea. The trio isn’t stopping there either, they plan to conduct more research—they want to know what exactly is happening inside the seeds when exposed to the bacteria—looking to see if perhaps there is another, simpler, cheaper and easier way to set off the speed-up reaction.

© 2014 Phys.org (Phys.org) —Quite a claim: a sculpture as the smallest creation of the human form in history. The sculptor, Jonty Hurwitz, said he loves the Internet. That is because, since the nanosculpture exhibit launch, so many people have viewed his nanosculpture work online and the work has been covered by numerous sites around the world. He created the nanosculptures using a 3D-printed photosensitive material. Softpedia’s Sebastian Pop delivered an account of the creation process and aftermath. A key word about the sculpture was “were,” he said, since the lifespan of the sculptures was accidentally cut short, by the man’s colleague who made an attempt to see them from a different angle. Hurwitz had spent ten months on seven sculptures; but the images remained. Sarah Anderson in 3DPrint.com referred to this as impressive art that we will never see, at least not with the naked eye, as the sculptures are so small. He did a series of seven sculptures. The largest, she said, is about the width of a human hair; the smallest is less than half that width. Hurwitz did not achieve this alone; he recognized this was an effort where art meets science. It was a case of creating art with the use of quantum physics. Hurwitz enlisted a team to work this out. Hurwitz said, “The only way to perceive these works is on the screen of powerful scanning electron microscope. So how can you ever know that this sculpture really exists? Your only way to engage with it is through a screen, and a mouse separating you and the art via a vacuum and a series of mathematically mind-blowing quantum processes that shower the art with particles to map its contours. Can you be sure of its existence if your basic senses are telling you that nothing is there? The line between myth and science is fine.”Multiphoton lithography was the technique used. “If you illuminate a light-sensitive polymer with Ultra Violet wavelengths, it solidifies wherever it was irradiated in a kind of crude lump. Some of you may have experienced a polymer like this first hand at the dentist when your filling is glued in with a UV light. If however you use longer wavelength intense light, and focus it tightly through a microscope, something wonderful happens: at the focus point, the polymer absorbs TWO PHOTONS and responds as if it had been illuminated by UV light, namely it will solidify. This two photon absorption occurs only at the tiny focal point – basically a tiny 3D pixel (called a Voxel). The sculpture is then moved along fractionally by a computer controlled process and the next pixel is created. Slowly, over hours and hours the entire sculpture is assembled pixel by pixel and layer by layer.”He credits the support he received from experts from the Institute of Microstructure Technology, Karlsruhe Institute of Technology, for fabrication and imaging and advice from Weizmann Institute of Science. “Trust,” a piece depicting a female human model, is around 80 x 100 x 20 microns. Rodin’s hand sculptures diagnosed as part of exhibit Explore further Credit: Jonty Hurwitz “He used around 250 cameras to gather all the photos he needed for the subjects of study, all arranged in a dome around the woman, sculpture, etc. Then he spent 10 months designing, sculpting and rendering virtual models, with the help of a high-powered program that reassembled the images into ‘digital clay,’ wrote Pop. “Finally, the models were ready to be 3D printed.” Had they survived, he remarked, “We’d have liked to see a mirror+microscope installation in a museum exhibit, where visitors would take a peek at the little marvels.” More information: www.jontyhurwitz.com/nano This document is subject to copyright.

Luminous blue variables (LBVs), also known as S Doradus variables (after S Doradus, one of the brightest stars of the Large Magellanic Cloud), are rare and unstable massive evolved stars exhibiting strong photometric and spectroscopic variability related to transient eruptions. So far, only about 40 LBVs are known in our Milky Way galaxy and in the galaxies of the Local Group.However, the cause of eruptions in LBVs is not fully understood and is still debated. Astronomers suppose that such eruptions could be caused by high rotation, radiative pressure, turbulent pressure, internal dynamic mechanisms, binarity, or they could be triggered by a combination of some of these mechanisms. Spotting new eruptions could help determine the exact cause, which could improve our understanding of stellar evolution of massive stars.Now, a group of astronomers led by Julio Campagnolo of the National Observatory in Rio de Janeiro, Brazil, has observed new eruptions in two LVBs, designated R 40 and R 110. R 40 (also known as RMC 40), located in the Small Magellanic Cloud. They are about 280 times larger than the sun, with a mass of approximately 16 solar masses. When it comes to R 110 (or RMC 110), residing in Large Magellanic Cloud, it has a radius of more than 300 solar radii and is ten times more massive than the sun.Campagnolo’s team conducted high-resolution spectroscopic observations of R 40 and R 110 using the Fiber-fed Extended Range Optical Spectrograph (FEROS) mounted at 2.2 m ESO-MPI telecope at La Silla Observatory (Chile) and photometric observations of these two LVBs by utilizing the 0.6 m telescope Boller & Chivens at the Pico dos Dias Observatory in Brazil.”In this paper, we present the detection of new eruptions for two LBVs in the Magellanic Clouds R 40 and R 110, based on new spectroscopic and photometric data,” the researchers wrote in the paper.According to the study, both LBVs experience ongoing eruptions. In R 40, the astronomers detected a strong eruption that reached a V magnitude of 9.2 in 2016, which is around 1.3 mag brighter than the minimum registered in 1985 and also much stronger than the previous eruption recorded in 1996. As a result of the new eruption, the effective temperature of R 40 dropped to about 6,100 K, what made it one of the coolest LBVs known to date.Contrary to R 40, R 110 is now passing through a weak eruption, with a maximum V magnitude of 9.9 mag in 2011. The new eruption is weaker than the previous one in 1994 and about 0.2 mag fainter than the first such event detected in this star in 1990. Due to the new eruption, the effective temperature of R 110 dropped to about 8,500 K.In concluding remarks the astronomers noted that still more observations are necessary in order to determine the periodicity of the eruptions in R 40 and R 110. They call for more comprehensive observational campaign that could uncover more insights into such events in these two LBVs.”As for each star just two eruptions have been recorded, it is not possible to derive a periodicity for these events. Thus, an observational campaign, associated with photometry, spectropolarimetry and high-resolution spectroscopy, covering not only the V band but also other bands is definitely necessary to follow up these eruptions and better derive their characteristics, and also identify new eruptions,” the authors concluded.

DOI: 10.1051/0004-6361/201731785AbstractWe performed a spectroscopic and photometric analysis to study new eruptions in two luminous blue variables (LBVs) in the Magellanic Clouds. We detected a strong new eruption in the LBV R40 that reached V∼9.2 in 2016, which is around 1.3 mag brighter than the minimum registered in 1985. During this new eruption, the star changed from an A-type to a late F-type spectrum. Based on photometric and spectroscopic empirical calibrations and synthetic spectral modeling, we determine that R,40 reached Teff=5800−6300~K during this new eruption. This object is thereby probably one of the coolest identified LBVs. We could also identify an enrichment of nitrogen and r- and s-process elements. We detected a weak eruption in the LBV R 110 with a maximum of V∼9.9 mag in 2011, that is, around 1.0 mag brighter than in the quiescent phase. On the other hand, this new eruption is about 0.2 mag fainter than the first eruption detected in 1990, but the temperature did not decrease below 8500 K. Spitzer spectra show indications of cool dust in the circumstellar environment of both stars, but no hot or warm dust was present, except by the probable presence of PAHs in R,110. We also discuss a possible post-red supergiant nature for both stars. (Phys.org)—Astronomers report the detection of new eruptions in two luminous blue variables, known as R 40 and R 110, located in the Magellanic Clouds. The finding, presented December 5 in a paper published on the arXiv pre-print repository, could shed new light on the final phases of stellar evolution process.

Completely rattled by the total rout suffered in Delhi Assembly polls, the Congress on Tuesday even refused to hold its daily briefing with media-persons. Instead a statement from party president Sonia Gandhi was issued which said that the party accepts “the will of the people with humility” and would “sincerely introspect the reasons behind its loss.”After being completely decimated in Delhi, Congress’ campaign in-charge Ajay Maken and Delhi’s in-charge PC Chacko resigned from their respective posts. Maken along with other 69 Congress candidates was defeated in the election. “I believe I should take responsibility and therefore resign. I was face of the Congress campaign and haven’t been able to win the seat which I contested in as well. This result has nothing to do with party leadership,” Maken told reporters.

The official function at the Naqshband Sahib Martyrs’ graveyard was presided over by the Chief Minister but the BJP ministers did not show up, indicating strains in the BJP-PDP coalition government. A BJP spokesman said although the ministers were in Delhi for a meeting with party president Amit Shah, the function at Martyrs’ Graveyard had no relevance to their party.“The 1931 martyrs have no relevance for us as a party. If they do not respect our leaders like Shyama Prasad Mookerjee, why should we (reciprocate)!” BJP spokesman for Kashmir Khalid Jehangir said. The function was to honour martyrs who laid down their lives fighting the Dogra rule in 1931.

Like they say ‘a diamond cuts a diamond’,” Sayeed said. Welcoming the recent meeting between Prime Minister Narendra Modi and his Pakistani counterpart Nawaz Sharif in Russia, Sayeed said peace in the region can only come through sustained and meaningful dialogue between India and Pakistan. He said both India and Pakistan have to resolve their differences by talking to each other for lasting peace in the region. Sayeed, without naming BJP, hit out at attempts to erode the special status of the state. “Jammu and Kashmir has a unique status and identity. I am saying it is a treasure for us. The power of our Assembly is supreme (in the state). If Parliament passes a law, it is our (Assembly’s) choice whether to implement it or not. We have a separate Constitution. We have a state flag alongside the national tricolour. We have state subject (law),” Sayeed said to applause from the audience. Highlighting the importance of democracy, the Chief Minister said the gun will not resolve any problem as it only brought destruction. “It is the ballot by which you can change your fate. You voted in 2002 and this time (2014) you decided that (the government) will be formed here.

In the age of selfies, it’s important to get your hair and make up in place to get the best frame. So make sure you are opting for the perfect trend to keep the like button buzzing on social media.Experts list down ways for seemingly perfect and classy hair and make up everyday. Select hairstyles that are flattering to you: The hairstyle you opt for, should complement your face cut and the outfit that you are wearing. Avoid extreme hairstyles; you don’t want a hairdo bigger than your head. Try not to completely pull your hair back from your face, as this could make you look older. Also Read – Add new books to your shelfEliminate flyaways: Ladies obsessed with picture perfect hair understand the necessity of moisturizing the hair to avoid flyaways. When our hair lacks moisture, it tends to look and feel dry, brittle and unhealthy. Spending time outside in the sun can majorly influence the moisture (or lack of) in your hair. Thus, use of hair serums, masks and sun protection is a must to maintain your hair’s health and protect it from damage.Go a little messy: Messy hair never goes out of style. So, just when you think you’ve styled your hair, toss your coif around to loosen things up in a right amount and you are all set to rock the camera. Also Read – Over 2 hours screen time daily will make your kids impulsiveSelect hair colour that enhances your hair: If you are planning to get those natural hair coloured, try the latest colours which go well with the Indian skin tone like honey brown, wine, caramel, chocolate brown in a balayage with highlights instead of going for global or simple highlighting. You must choose a hair colour that matches with your skin tone and don’t just go for any random hair colour.Don’t shy away from volumizing products: A regular and a great haircut is the foundation of any great hairstyle for fine hair-one that provides with volume in appearance. Other than this, a bit of strategic teasing along with volumizing products will work wonderfully on the camera. For the perfect make upSunscreen is a must: No matter what, you should apply sunscreen to protect your skin from harmful ultraviolet rays. Apply sunscreen before you apply foundation or primer. Titanium based or Zinc oxide based sunscreens are considered to be best for the sensitive skin type. Summer make up kit must have a spray sunscreen or a gel-based sunscreen with minimum SPF 30.Kind of make up products: Use only long-wearing, smudge-proof, waterproof cosmetic that stays for long and gives a perfect finish to your makeup. Use face powder to set makeup and reduce the excess shine on your face. Foundation with a matte finish works as a miracle.Avoid the catchy look: Everyone loves a nice glow that shimmer gives us, but there is a big difference between a healthy radiance and an over-the-top shine. Do not use any cosmetics with a shimmery, shiny or glowing finish it can make you look bad in the photographs. A concealer and a nude lip colour is all you need this summer.Maximise the impact of those eyes: Curled lashes and mascara are musts as both open up your eyes, and the eyes are the focal point of a picture. Use clear light to medium colour eye shadow for highlighting. The more open they are, the more the light hits them and that’s what makes them twinkle.
