Caltech scientists solve decade-long mystery of nanopillar formations Oct 23, 2009
In capillary flowor capillary actionthe attractive force, or cohesion, between molecules of the same liquid (say, water) produces surface tension, the compressive force that is responsible for holding together a droplet of water. Since surface tension tends to minimize the surface area of a liquid, it often acts as a stabilizing mechanism against deformation caused by other forces. (EurekAlert!)
The European Union - the new sleeping giant? Oct 19, 2009
"The attractive force of the EU as a political, societal and economic model remains immensely powerful," the German Marshall Fund said earlier this month. "Numerous countries are standing in line to join.". (San Francisco Chronicle -- Politics)
Not your average reality star Sep 9, 2009
"If anything, the camera crew was an attractive force and people came up to me and asked me what they were doing and then they introduced themselves," Nelson said. The fourth of six children, Nelson is the first child from his family to attend college outside of the state of Utah, where his family lives. (GW Hatchet, Washington DC)
Lahey Clinic recognized for nursing excellence Aug 25, 2009
Because quality nursing is one of the most important factors in enlisting high caliber physicians and specialists, Magnet status becomes an attractive force that extends to the entire facility. Lahey achieved this distinction after a multiyear application process that included submission of a 2,200-page supporting document and a four-day visit by appraisers from ANCC. The appraisers visited Lahey s medical centers in Burlington and Peabody, and invited comments from nurses, administrators,... (Burlington Union, MA)
'Repulsive' Side To Light Force Could Control Nanodevices Jul 14, 2009
Previously, the engineers used the attractive force they discovered to move components on the silicon chip in one direction, such as pulling on a nanoscale switch to open it, but were unable to push it in the opposite direction. Using both forces means they can now have complete control and can manipulate components in both directions. (Science Daily)
Streaming Sand Grains Help Define Essence Of A Liquid Jun 25, 2009
ScienceDaily (June 25, 2009) University of Chicago researchers recently showed that dry granular materials such as sands, seeds and grains have properties similar to liquid, forming water-like droplets when poured from a given source. The finding could be important to a wide range of industries that use "fluidized" dry particles for oil refining, plastics manufacturing and pharmaceutical production. (Science Daily)
What is a Resting Potential? Apr 13, 2009
Negatively-charged molecules inside the cell exert an attractive force on the positive potassium ions, causing most of them to remain inside the cell. Transmission of Nerve Impulses. (Suite101.com)
If galaxies are all moving apart, how can they collide? Mar 19, 2009
Early on, the universe was much denser than it is today, and the attractive force of gravity was winning the battle, on scales both large and small. Clouds of gas condensed to form stars and galaxies, and galaxies drew together to form clusters. (Scientific American)

" Writing that echoes Ian McEwan's description of the ballooning accident in Enduring Love. This is a comprehensive collection of works by Latvian artists in Australia. It's impossible not to be impressed by the research, the design, the wit, the spanking bright prose of these pieces. Fragments from the past are now a present tense. Reviewed by Bob Carr. Marilynne Robinson's spotlight is still in Gilead but it has moved down the street to the Boughton household. The question of what constitutes... (Sydney Morning Herald -- Entertainment)
Cosmologists seek to identify the physics of key components in their picture of the universe Mar 6, 2009
A repulsive force, dark energy pushes the universe apart and overwhelms gravity, the attractive force that all matter exerts. Dark energy is invisible, but astronomers are able to see its influence on clusters of galaxies that formed within the last few billion years. (Univeristy of Chicago Chronicle, IL)
Super Solar Cells? Certain Nanocrystals Shown To Generate More Than One Electron Feb 19, 2009
(May 31, 2007) Scientists have demonstrated in the laboratory that the Casimir force -- the small attractive force that acts between two close parallel uncharged conducting plates -- can be changed using a beam of. (Mar. (Science Daily)
Engineers Revolutionize Nano Fabrication Feb 12, 2009
19, 2007) Micro-electro-mechanical systems, popularly referred to as MEMS, in small electronic devices often fail because of adhesion and stiction - the attractive force between the surfaces of interacting. . (Science Daily)
