REUTERS/Amit Dave/File Photo NEW DELHI (Reuters) - An Indian scientist whose team has developed a genetically modified (GM) mustard variety that is inching towards a possible commercial launch said he could soon hand to a state agency a GM cotton variety that can rival Monsanto's seeds. Deepak Pental and his colleagues at the Delhi University worked on GM mustard for around a decade, and a government committee said on Monday it found the seeds to be safe for "food/feed and environment". Reuters reported the technical clearance last month for what could be the country's first GM food crop. (http://bit.ly/2cnUOkZ) "The government has taken the right path and experts have looked at all the data," Pental told Reuters on Tuesday, acknowledging that public opposition to lab-altered food remains fierce. "Our scientists have the capability to do more, but you will have to strengthen research further, educate people." Prime Minister Narendra Modi's nationalist government, keen to cut the country's heavy annual food import bill, will soon decide on the commercial launch of the high-yielding mustard and plans to indigenously develop other GM food to reduce reliance on multinationals such as Monsanto. The move has been opposed by activists and politicians amid fears GM food could compromise food safety and biodiversity. Some experts have also questioned claims that GM crops are more productive than normal varieties. St. Louis, Missouri-based Monsanto dominates India's GM cotton market, but is embroiled in a high-stakes battle with the government which wants the company to cut the royalty it charges for its technology, apart from a proposal that will make the seed giant share its technology with local firms. Monsanto has even threatened to pull out, prompting Environment Minister Anil Madhav Dave to say that Indian scientists are capable of meeting the requirements of its farmers on their own. New Delhi-based Pental said he was willing to help the government with that goal and would approach the state-run Indian Council of Agricultural Research (ICAR) to pass on a laboratory-tested GM cotton variety his team has developed over the past decade. The variety is similar to Monsanto's Bt cotton but can be more resistant to pests, Pental said, adding he handed another GM cotton variety to ICAR last year for further research. No field trial has yet been done on either cotton strands. This comes at a time when Monsanto has withdrawn an application to sell its next-generation cotton seeds protesting the Modi government's proposal to force it to share its technology with local seed companies, which has also worried other foreign firms such as Bayer, Dow, Dupont Pioneer and Syngenta. Experts warn that even if India did develop a home-grown GM cotton variety in the next few years, it would struggle to sustain a programme that needs to refresh seeds every decade or so.

It is shown that the nucleotide sequences in DNA molecules have cluster-scaling properties (discovered for the first time in turbulent processes [K.R. Sreenivasan, A. Bershadskii, J. Stat. Phys. 125 (2006) 1141]. These properties are relevant to both types of nucleotide pair-bases interactions: hydrogen bonds and stacking interactions. It is shown that taking into account the cluster-scaling properties can help to improve heterogeneous models of the DNA dynamics. Two human genes: BRCA2 and NRXN1, have been considered as examples. © 2010 Elsevier B.V. All rights reserved. Source

The universal role of the nonlinear one-third subharmonic resonance mechanism in generation of strong fluctuations in complex natural dynamical systems related to global climate is discussed using wavelet regression detrended data. The role of the oceanic Rossby waves in the year-scale global temperature fluctuations and the nonlinear resonance contribution to the El Niño phenomenon have been discussed in detail. The large fluctuations in the reconstructed temperature on millennial time scales (Antarctic ice core data for the past 400 000 years) are also shown to be dominated by the one-third subharmonic resonance, presumably related to the Earth's precession effect on the energy that the intertropical regions receive from the Sun. The effects of galactic turbulence on the temperature fluctuations are also discussed. © 2012 The Author(s) Published by the Royal Society. Source

It is shown that a chaotic (deterministic) order, rather than a stochastic randomness, controls the energy minima positions of the stacking interactions in the DNA sequences on large-scales. The chaotic order results in a long-range chaotic coherence between the two complimentary DNA-duplexs strands. A competition between this broad-band chaotic coherence and the resonance coherence produced by genetic code has been briefly discussed. © 2011 Elsevier B.V. All rights reserved. Source


It is shown that the correlation function of the mean wind velocity generated by a turbulent thermal convection (Rayleigh number Ra∼1011) exhibits exponential decay with a very long correlation time, while the corresponding largest Lyapunov exponent is certainly positive. These results together with the reconstructed phase portrait indicate the possible presence of chaotic component in the examined mean wind. Telegraph approximation is also used to study the relative contribution of the chaotic and stochastic components to the mean wind fluctuations and an equilibrium between these components has been studied in detail. © 2010 American Institute of Physics.
