Metals That Heal Themselves

A nuclear reactor is a grueling place for the metals there�all the wear-and-tear caused by neutron activities inside the reactor can make them swell and become brittle over time.
Researchers at Los Alamos National Laboratory in New Mexico have shown that by altering the microstructure of metals, metallurgists may be able to make reactor parts that are self healing.
Blas P. Uberuaga, Xian-Ming Bai and colleagues conducted computer simulations of the long-term impact of neutron emissions on copper � not because much copper is used in nuclear plants, but because it is a relatively well-modeled metal. Their findings are published in Science.
When a neutron hits metal, it displaces atoms within the crystal lattice. In a metal with a largely uniform structure, these atoms move to the surface, eventually causing the metal to swell, and the vacancies they leave behind can lead to voids that further weaken the material.
But it is possible to fabricate metals that have a nonuniform structure, with very small crystal grains, or regions of different phase or orientation. When atoms are displaced in this nanocrystalline material, rather than traveling to the surface they migrate to the boundaries between the grains. In their simulations, the researchers found that these atoms can then travel back away from the boundary and, if they find a vacancy, fill it, in effect healing the defect.

Bacteria are �big thinkers�

Scientists at the University of Tennessee, Knoxville have found that bacteria are �big thinkers� and more capable of complex decision-making than previously thought, a discovery that could lead to innovations in medicine and agriculture fields.Until now, scientists have been unable to study how bacteria�s individual receptors directly affect their behaviour and ability to adapt to the environment.

Networking sites boost privacy

Did you notice that resently Facebook took a step towards opening up parts of its site to outsiders by introducing more options for user�s privacy settings.
The changes will make it easier for Facebook�s more than 350 million users to limit who sees their musings, videos, photos and other personal information, but will also give them the opportunity to expose a wider swathe of their information to a broader internet audience.
The move comes as internet search engines like Google and Microsoft are showing interest in incorporating the growing trove of user-generated content from social media websites into their search results.
Schrage, Facebook Vice President of Global Communications and Public Policy said Facebook users will be greeted with a message on Wednesday presenting them with new options to customise privacy settings and directing them to a new, simplified overview page of all their personal privacy settings.
