Animals in the wild found to use running wheel if given the

first_img(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.

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.

Best of Last Week Questioning Higgs finding possible alternative to antibiotics and

first_img 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.last_img read more

Dish it out

first_imgIf 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!last_img read more
