Decline of species at Chernobyl linked to DNA
Brightly colored birds and birds that have a long distance migration were some of the organisms most likely to be affected by radioactive contaminants; one scientist says: “One explanation may be that these species have, for whatever reason, less capable DNA repair mechanisms”

U.S. has 5,113 strategic nuclear warheads -- down from 31,225 in 1967

Risks of laser-based uranium enrichment outweigh rewards
Researchers argue that laser-based uranium enrichment is not the way to bolster nuclear power: the technique, which involves the separation of isotopes by lasers, would save U.S. households no more than about $2 per month in energy costs, while increasing dramatically the risk of nuclear weapons proliferation

Northrop Grumman unveils latest version of Wheelbarrow UGV
Northrop Grumman’s Wheelbarrow unmanned ground vehicle (UGV) was first used by British Army bomb disposal teams during “The Troubles” in Ireland in the 1970s; since then it has gone through a number of design upgrades to extend its capabilities and meet changing military and first response needs; the company has just unveiled the latest version of this veteran robot

Uranium-mining nations ignore UN-mandated measures on nuclear terror
In the aftermath of the 9/11 terror attacks and the 2004 uncovering of the Pakistan-based A. Q. Khan nuclear smuggling network, the United States pushed Resolution 1540 through the UN, which required states to impose strict security measures on nuclear materials and report on the progress they have made in this regard; many states have not bothered to report — almost all them in Africa; especially worrisome is the situation in Niger, the Democratic Republic of the Congo, Zambia, Malawi, and the Central African Republic

Worry: gravitational force would cause nuked asteroids to reform
The only way to prevent large asteroids from hitting Earth is to use nuclear weapons to blast them to pieces; scientists find that this is not good enough: the gravitational force among the asteroids fragments would cause the asteroid to reform, “Terminator”-like, within hours

Pentagon orders accelerated production of 15-ton bunker buster
The Obama administration is inching toward a dialog with Iran over the latter’s nuclear weapons program, but at the same time it readies the means to destroy Iran’s capabilities should the dialog fail

Worries grow about safety of Pakistan's nuclear weapons facilities
All the terror strikes in Pakistan in the recent past have been suicide attacks, but the attack on the Pakistan Army’s General Headquarters in Rawalpindi three days ago was more of a commando attack carried out by well-trained jihadists; experts worry that such military-style tactics could be used against Pakistani nuclear sites

A first: Criminals steal nuclear material, than demand ransom for its return
Criminals in Argentina steal cesium-137 from a drilling company, then demand $500,000 and threaten “to make this city glow” if they did not get the money

Radioactive rabbit poo found at plutonium production site
A clean-up survey at the Hanford site in Washington State, where military-grade plutonium was produced during the early years of the cold war, discovered radioactive jackrabbit droppings around the site; the rabbits burrowed in the area and discovered the tanks in which nuclear waste is stored; they liked the salty taste of the radioactive cesium and strontium salts, so they began drinking and licking them routinely

Revelations about Iran's facility raise questions about U.S. intelligence
Both the 2003 “slam dunk” assertion about Iraq’s WMDs, and the 2007 NIE’s conclusion that Iran had “halted” its nuclear weapons work, were absurdities; we should worry about the fact that they came to the surface — and influenced policy

Missile defense system that might just work
The Obama administration’s decision to scrap the Bush administration’s plan to place ballistic missile defense systems in Poland and the Czech Republic, and replace it with short-range defensive systems closer to Iran, makes sense; instead of making a political point to Russia, the U.S. might now have in place a defensive system that works

Fujitsu asks terrorists whether they would use its software for WMD
Fujitsu runs a patching site for Sun Microsystems’ Solaris Unix variant; the company asks end-users to fill out a survey before downloading the latest patch, and the first question asks whether the customer would be using the patch to build WMD; even if you admit to building a nuclear bomb, Fujitsu allows you to download the patch; either Fujitsu targets really honest terrorists, or the company wants to use the information in its advertising (as in: “5% of our customers are terrorists who use our software to build weapons of mass destruction”)

How to verify a comprehensive Iran nuclear deal
With the negotiation between the P5+1(the United States, European Union, Britain, France, Russia, and China) and Iran resuming yesterday (Wednesday) about a set of parameters for an eventual Joint Comprehensive Plan of Action, the shape of a final deal about Iran’s nuclear program has emerged. Many important provisions of a final deal, however, remain to be negotiated in the coming months. David Albright, the president of the Institute for Science and International Security, says that a critical set of these provisions involves the adequacy of verification arrangements which would be in place to monitor Iran’s compliance with a deal. Tehran’s long history of violations, subterfuge, and non-cooperation requires extraordinary arrangements to ensure that Iran’s nuclear program is indeed peaceful.
