• Secretary-General Ban Ki-moon's report, says there is now unprecedented political momentum globally to end conflict-related sexual violence but more action is needed regionally and nationally to respond to these crimes.
• Covering 21 countries of concern in Europe, Asia, Africa, South America and the Middle East, the report shows that sexual violence in conflict is truly is a global crime.

Stay on release of Rajiv Gandhi murder convicts

• In a major setback to the Tamil Nadu government the Supreme Court has extended the stay of an order passed on February 19 directing the release of seven life convicts in the Rajiv Gandhi assassination case.

• On February 20, the court had directed the Tamil Nadu government to maintain status quo in its decision to release the three convicts Sriharan alies Murugan, T.Suthendraraja alia Santhan and A.G. Perarivalan allias Arivu, whose death sentence was commuted to life term on February 18 as well as in the release of four other convicts Nalini, Robert Pious, Jayakumar and Ravichandran. On Friday the court said the interim order of staying the release would continue till the final decision was rendered by the five-judge constitution Bench.

• A bench of Chief Justice P. Sathasivam and Justices Ranjan Gogoi and N.V. Ramana, while extending the stay, referred to a Constitution Bench the issues raised by the Centre on the powers of the State government to release the convicts after the same had been rejected by the President or the Governor in exercise of their clemency powers. The Bench gave this verdict on the writ petition filed by the Centre challenging the Tamil nadu government's decision to release the seven convicts in the Rajiv Gandhi assassination case.

• The Bench framed seven questions to be considered by the Constitution Bench, including whether the State could exercise its remission powers to release a life convict after the same had been exercised by the President or the Governor or by the apex court by commuting the death sentence into life term.; what was the meaning of `consultation’ contemplated in Section 432 Cr.P.C. and whether it would mean concurrence with the Central government; whether imprisonment for life would mean imprisonment for the rest of life without remission; whether the court could evolve a special category of sentence in certain cases and substitute death sentence into life sentence for rest of life and make such an order beyond the power of remission and which was the appropriate government, either the State or the Centre or there could be two parallel government which could exercise the power of remission.

Helix’s twisted cousin

• The helix is a complex shape found in many natural settings. It is commonly illustrated by the shape of DNA molecules. The roots of some plants also burrow as helices, like corkscrews winding downward in search of richer soil. But during an experiment at Harvard University, mechanical engineers were surprised when a pair of rubber ribbons expected to form a helix did not, buckling into a shape rarely observed in nature.

• Every helix winds in a left or right direction. The engineers observed what they called a hemihelix: a helix that changes its direction midway. The region along which it changes its direction is called aperversion. Charles Darwin observed plant tendrils forming hemihelices in 1888.

• Starting with two strips of an elastic polymer of different lengths, the engineers stretched the shorter one to be the same length as the other. Then, while maintaining the stretching force, they joined the strips side-by-side. As the force was dwindled, the bi-strip twisted and bent to create either a helix or a hemihelix.

• As energy due to stretching flows through the strip, the strip twists to reduce the load it bears. However, imperfections in the material could cause the strip to buckle at certain places, where perversions form and the chirality reverses.
