(Phys.org) —A pair of researchers in the Netherlands has found that if a running wheel is placed outdoors in a natural setting, wild animals will come and run on it. Neurophysiologists Johanna Meijer and Yuri Robbers describe in a paper they’ve had published in Proceedings of the Royal Society B: Biological Sciences, how they set up running wheels in natural settings then filmed wild animals using the wheels. Scientists, researchers and animal rights advocates have argued over the years about the nature of mice running on wheels in their cages. Rights activists claim the running is a form or neurotic behavior brought about by living in the confines of a small cage. Some researchers, on the other hand, have suggested that the mice seemed to like, or enjoy running on the wheel, and even exhibited unhappy behavior if a wheel was removed. To learn more, Meijer and Robbers decided to carry out a very simple experiment—they set up a running wheel in their backyard, then used an infrared camera to capture on tape how animals in the wild would respond.To get things, rolling, so to speak, the researchers also laid down some food near the wheel to attract some animals. They also put the wheel inside an enclosure with a small entranceway to keep large animals from knocking the wheel on its side. Examination of the film showed that a lot of animals found the wheel, climbed on and began running on it. Granted, most of the animals were mice, but the camera also caught frogs, rats, shrews and even slugs. The frogs didn’t actually run, they simple hopped form one side to the other causing the wheel to roll back and forth, and the slugs appeared to arrive on the wheel by accident. Still, the results were so encouraging that the team set up another wheel and camera in a nearby dune area not accessible to the general public.In all the team recorded over 200,000 animals using one or the other of the wheels over a three year period. The main runners were mice, some of which jumped on, ran for a while, jumped off, then jumped back on and ran some more. One mouse ran for an incredible 18 minutes.

The researchers claim the animals ran on the wheels because they enjoyed it, which could be a little bit of anthropomorphizing, as no one has been able to prove that animals other than humans experience emotions. Still, the experiments should put to rest the argument about whether mice in the lab are running on wheels because they live in cages—they’ll do it anywhere they find one. A slug using a running wheel Shark Wheel on a roll to reinvent skateboarder experience More information: Wheel running in the wild, Published 21 May 2014 DOI: 10.1098/rspb.2014.0210AbstractThe importance of exercise for health and neurogenesis is becoming increasingly clear. Wheel running is often used in the laboratory for triggering enhanced activity levels, despite the common objection that this behaviour is an artefact of captivity and merely signifies neurosis or stereotypy. If wheel running is indeed caused by captive housing, wild mice are not expected to use a running wheel in nature. This however, to our knowledge, has never been tested. Here, we show that when running wheels are placed in nature, they are frequently used by wild mice, also when no extrinsic reward is provided. Bout lengths of running wheel behaviour in the wild match those for captive mice. This finding falsifies one criterion for stereotypic behaviour, and suggests that running wheel activity is an elective behaviour. In a time when lifestyle in general and lack of exercise in particular are a major cause of disease in the modern world, research into physical activity is of utmost importance. Our findings may help alleviate the main concern regarding the use of running wheels in research on exercise.

String field theory could be the foundation of quantum mechanics In other news, researchers working to solve the problem of growing resistance to antibacterial agents have found a possible alternative to antibiotics—artificial nanoparticles made of lipids that serve as decoys, attracting harmful bacteria and preventing them from attacking their actual target. Equally pressing is a better understanding of what is happening to our world as global warming continues unabated. Researchers at Berkeley identified a new driver behind Arctic warming—turns out the open ocean is far less efficient at emitting in the far-red spectrum than is ice, which means the Arctic Ocean traps more heat than has been thought.In news from space, a team of astronomers believe they have solved the mystery of the bizarre object at the center of our galaxy—they think it’s a pair of binary stars. Meanwhile NASA’s Curiosity rover found a mineral match—showing that measurements taken from a distance match those of real minerals found on Mars. There was big news in biology as well, as a drug being tested in a clinical trial was shown to completely reverse diabetes in human islets and mice. More research will have to be done, of course, but thus far, the researchers report that the drug looks promising.And finally, for those who have been wondering, researchers have found that those who adhere to the Mediterranean diet are likely to see lasting health benefits—they found that the diet led to improved blood flow to cells lining blood vessels, for up to a year after the diet was stopped—an indicator of overall general good health.

Also, two physicists with USC suggested that maybe string field theory could be the foundation of quantum mechanics—providing a basis for all of physics and perhaps answering the question of where quantum mechanics actually comes from. And another team of physicists proposed the identification of a gravitational arrow of time—they’ve taken time out of mathematical equations used to describe the total energy of the universe allowing them to split equations that describe the evolution of the universe into two parts.
If you have had enough of the regular Dominos and the Pizza Hut pizzas – the ones which you leave out the crust and are more than often unhappy with the toppings? The Capital has had the luck to have a handful of places that serve you a perfect pizza that you will find very little to complain about. The thin crust, some really yummy cheese and some toppings you could die for. Fat Lulu’s in Gurgaon has won its own set of pizza loyalists and also a few from other parts of NCR, who often brave the traffic to get a bite of the ‘ thin crust NY style gourmet pizza’. As they put it – this pizzeria is inspired by the American culture of famous gangs and mobsters that originated from Italy and brought unique thin-crust style pizza with them to the streets of New York. With interiors that remind of a casual, cosy eatery in some corner of the Big Apple, Fat Lulu’s at DLF Shopping Mall, Arjun Marg, DLF Phase I, surprised us. Also Read – ‘Playing Jojo was emotionally exhausting’While they give you the option to create your own pizza with a choice of vegetarian and non vegetarian toppings and also a pick from six other kinds of cheese besides the mozarella – their own selections are quite a hit. The Soho (pepperoni, parma ham, ground lamb and Italian sausage) and Bronx (sour cream, mozarella, chicken, capsicum, onion and bacon) get our thumbs up in the meat lovers’ section. If you are the type to be adventurous – they have a very interesting shrimp pizza they call Park Avenue. For the vegetarians Fat Lulu’s vegetarian pizza is what we would suggest – it has Italian ratatouille – zucchini, bell peppers, mushroom and olives. And the classic Margherita is spot on – with the perfect thin crust and the cheese.Pizzas top their orders but they also have an impressive list of pastas and salads on offer as well. With a 16 inch non-veg pizza available for Rs 800 and a non-veg pasta for Rs 300 (both without taxes) the prices are decently easy on the pocket as well. The restaurant is hoping for a liquor license soon and one can enjoy their pizza with some chilled beer. Definitely something we would come back for!

Also Read – ‘Playing Jojo was emotionally exhausting’Their satisfaction in doing their household chores or by fetching water from the well or by celebrating small festivals brightens their day and keeps them happy. As the wrestler in his wrestling arena only targets his opponent and cannot think anything beyond it, so is a villager, his village is his life and cannot think beyond it. As also the scenic beauty fascinates the artists with the mountains touching the skies or the horizon where the sky meets the depth of the seas, the tall mountains, the greenery, the lakes, and the breath-taking nature spreading its fragrance with a touch of godliness makes the viewer enjoy the picturesque view. The depiction becomes real to life and inspires the on-looker.

Congress MP Shashi Tharoor is likely to be questioned again next week in connection with his wife Sunanda Pushkar’s mysterious death as police looks to join the pieces in the case.Tharoor was questioned by police on January 19 for around four hours at the office of Anti Auto Theft Squad (AATS) in South Delhi’s Vasant Vihar.Sources on Sunday said the Special Investigation Team is likely to question the former Union minister again next week as they got very “little time” with him on January 19. Also Read – Company director arrested for swindling Rs 345 croreThey also said that as he was the “closest relative” of the deceased at the spot when she was found dead, he may be questioned several times as the SIT would want to ask him about the things which would arise during examination of other witnesses and people concerned.Speaking to reporters on Friday, Delhi Police Commissioner B S Bassi had also indicated Tharoor can be questioned in this connection again in “some days”.“Whatever we had spoken to him during the first questioning is being analysed and if we need further questioning, it will be done. Since it is a very involved case, there would be a need to talk to him again, so the SIT will call him again in some days,” he had said.52-year-old Sunanda was found dead in a room in the hotel on January 17 last year. Delhi Police filed a case of murder in the case on January 1 and an SIT was formed to probe the case. Since then, police has questioned a number of people in this connection including domestic aides of Tharoor, staff of the hotel where Sunanda was found dead, family friend Sanjay Dewan and the hotel doctor who pronounced her dead.
Four Points by Sheraton presented the show A Keralan Perspective for the first time since their 2008 exhibition Replacing works which focus on the Capital’s rich architecture. The paintings explore another area of India’s bounteous cultural history reflects the increasing cultural integration enabled uniquely by the world of art.Maity’s work already features prominently at Four Points by Sheraton in the form of sculpture. Through The Orient is a series of twenty works inspired by the artistes 2005 visit to China. Also Read – ‘Playing Jojo was emotionally exhausting’The watercolours are a-typical of comparative shows currently on display which feature predominantly his large-scale oils. Rather, this exhibition shows his mid-career preference for watercolour. In this instance, the technique of the artist is still delicate and entirely based on his exploration of light and atmosphere. The colours – yellow, red, blue – depict less the actual colour spectrum of the scene, but rather the time of day and the feeling of light passing over the various landscapes.In this series Maity also adopts a minimalism appropriate to Sino-aesthetics, as well as elements of calligraphy and line-work for which the country’s artwork is also famous.
Kolkata: Police conducted a raid at the chicken farm in Rajarhat on Monday after receiving information that some miscreants have managed to enter the farm that was sealed by the police earlier.It was on Monday morning when police received information that some people used the back gate of the farm to enter. Locals found some people entering the farm and it led to their suspicion as they knew it was sealed when police had raided it earlier.Police conducted a raid at the farm a few days ago after they came to know that there was a huge stock of meat from carcasses and at the same time, they had found huge size freezers in which the same was stored.
