first_imgThe trouble with earthquakes, other than their obvious devastation, is that thus far they have proved to be very nearly impossible to predict, despite considerable effort towards that goal; being able to do so would obviously save a lot of lives. Also, despite the fact that there is literally hundreds, if not thousands of years of anecdotal evidence suggesting that some animals may have some innate ability to predict quakes, modern research has instead been steadfastly focused on studying the Earth, rocks, faults, etc. Toads’ earthquake exodus More information: Int. J. Environ. Res. Public Health 2011, 8, 1936-1956; doi:10.3390/ijerph8061936 That may change now that biologist Rachel Grant, from the UK’s Open University has found evidence that toads can predict a quake up to several days before the ground starts shaking. She’s teamed up with NASA geophysicst, Friedemann Freund and the two of them, as they describe in their paper in the Journal of Environmental Research and Public Health, suggest that it might all be because of changes to the pond water in which the toads are living.Grant was studying the toads that lived in a pond near L’Aquila, Italy, in 2009 in the days just before a devastating earthquake struck. In those few days just before it happened, she noted that the toads began leaving. Their numbers dwindled from just under a hundred, to zero, causing her to write about her observations in the Journal of Zoology. That caught the attention of Freund, who was doing work for NASA in studying what happens to rocks when put under extreme stress, as in say, when an earthquake is in the making. He contacted Grant, and the two of them began investigating ways that such rock pressure could impact the environment where the toads lived.After some experiments in the lab, the two write that when rocks underground come under pressure as a result of geological processes, they let off charged particles. Such particles can very quickly rise to and above the surface of the Earth, impacting such things as pond water and the biological material in it. In the case of the pond in Italy, it seems the toads may have been reacting to changes they felt in the water itself as ions interacting with it react to form minute amounts of hydrogen peroxide. Or it seems possible that ions interacting with organic material in the pond caused substances to be released that either were toxic or less ominously, simply irritating. Either way, it would explain their sudden exodus.The problem with proving their theory though, is of course, they’d have to know when and where an earthquake is about to strike so as to allow them to set up testing equipment in advance. Perhaps the best that can be done at this point, is for such information to disseminated all over the world, so that if anyone happens to live near a pond, and notices that the toads are leaving, they would be wise to follow them.

The content is provided for information purposes only. Explore further The researchers, Claudio Maggi, et al., from Italy, Germany, and Spain, have published a paper on the microgears in a recent issue of the journal Small.”The modern tools of nanotechnology can be used to shape matter at the micron and nanoscale with a high degree of structural and morphological control,” Maggi, at the University of Rome, told Phys.org. “Recently researchers have started to investigate possible strategies to ‘give life’ to these structures and provide them with some mechanism for self-propulsion. The whole effort of miniaturizing machines becomes useless, however, if large and expensive equipment is still required to drive and control propulsion at the micron scale. For this reason, we are working on the development of advanced materials, collectively referred to as ‘active matter,’ that can convert some embedded energy source into directed motion.”The active matter materials used here are micromotors in the form of Janus particles. Like the two-faced Roman god, Janus particles have two faces, or surfaces, that give them an asymmetric character. Here, one side of each 5-µm particle is coated with platinum, so that when the particles are immersed in a hydrogen peroxide solution, they move in one direction. In a solution containing both Janus particles and passive 8-µm microgears, some of the self-propelled Janus particles collide with the microgears. The Janus particles then autonomously orient themselves so that their propelling direction runs along the sides of the gears, and their forward momentum locks them in place in the gears’ teeth. Up to six Janus particles can be lodged into the microgears’ six teeth.This strategy is similar to previous methods of moving microobjects that use the collective motion of bacteria or synthetic microswimmers. However, all of these previous methods have required high bacteria/microswimmer concentrations and moved in a highly random way, making it difficult to control and reproduce the motion. The biggest advantages of the new method are that it works with lower particle concentrations and the motion is highly deterministic. The researchers found that the microgear’s spinning speed increases linearly as the number of Janus particles locked into the gear increases from 1 to 3. With 4 particles and beyond, the speed flattens out and then begins to decrease, which is likely because the additional Janus particles deplete the hydrogen peroxide fuel so that the speed of all the particles decreases.”We have now demonstrated that active Janus colloids can self-assemble around a micro-fabricated rotor in reproducible configurations with a high degree of spatial and orientational order,” said coauthor Roberto Di Leonardo at the Italian National Research Council, and the coordinator of the research group. “The interplay between geometry and dynamical behavior leads to the self-assembly of autonomous micromotors starting from randomly distributed particles. Besides having a clear technological interest, our results demonstrate that understanding fundamental aspects of interactions in active matter systems opens the way to highly reproducible and controllable micromachines for lab-on-chip applications.”In the future, the researchers plan to investigate how tuning the concentration of hydrogen peroxide can be used to control the rotational speed of the micromotors. Controlling the speed is essential for lab-on-chip micromachines and other applications.The research was funded by two ERC Starting Grants and combines recent advances in catalytic propulsion (Grant n. 311529) and statistical mechanics of active matter (Grant n. 307940). Janus particles dock in between the teeth of a microgear to propel it forward. Credit: Maggi, et al. ©2015 Small Journallast_img read more

first_imgSeeing the world in a grain of sand, capturing the gist of life in a blob of paint — can a canvas capture that? Can devotion, in a land chockfull of contradictions and numerous religious thoughts , be perceived as an abstract and metaphysical piece of creative contemplation, essentially secular and spiritual work of art? The pensive and meditative portraits of spiritual gurus and godly figures of Buddha, Krishna, Shiva, Parvati and others by artists Satish Gupta, Shuvaprasanna, Sudip Roy, Puja Bahri, Prithvi Soni, Chottu Lal ,amongst others, exemplify just that beautiful tenet of Indian spiritual philosophies. Also Read – ‘Playing Jojo was emotionally exhausting’Evocative of complete surrender to the idol of their devotion, the artists dig into their inner selves to seek solace and a relief from the transient nature of life and the ephemeral world around, goading one towards a spiritual path of humility. There is a philosophical and mystical sophistication in their work as well as Sidharth’s art who paints using his hand made colors. The line between the sacred and the profane comes into full play in Sanjay Bhattacharya’s drawings in Pen, ink and water colors. Also Read – Leslie doing new comedy special with NetflixDevotion transforms into adulation and obsession as search for human and physical love, be it a man for a woman or mother for her child. It comes to the fore as in the courting couples and other figurative compositions in paintings by Asit Patnaik, Nayana Kanodia , Mousumi Biswas and Shipra Bhattacharya. The seeds of devotion planted in the mind by desire or awe blossom into love or respect for the chosen subject that often transforms individuals and their life. Depending on its intensity and echelon, ranging from adulation to obsession for a particular entity, cause, idea or faith, human or saintly, factual or fictional, its pursuit can turn things around into one of the two extreme modes of renunciation or revulsion. Then there are fluid depictions at cross roads between painting and sculpture by Venkat Bothsa. Evoking the flourish of the street painter, images of the lotus with the curling tendrils play themselves in painted steel in large dramatic sizes. The cryptic written word found often on the rear of public vehicles has communicated directions, slogans and sometimes nothing. The fonts were developed in an indigenous flavor, combining popular culture, street graffiti and a homegrown language. This is what Alex Davis looks into Devotion. The folk element continues to play through colorful paintings of Telangana women by Vaikuntam.Nature appears in a different mode and frame in Surya Prakash’s colourful landscape and Gurdeep Singh’s bright and colorful canvases. The changing life patterns and the world around are seen to get differently moulded in metal sculptures by Dimpy Menon, Gautam Bhatia and Enas MJ.last_img read more
