New approach can control large complex networks, from cells to power grids As the world becomes increasingly connected, the need to ensure the proper functioning of its many underlying networks -- such as the Internet, power grids, global air transportation and ecological networks -- also is increasing. But controlling networks is very difficult. Now a Northwestern University research team has developed the first broadly applicable computational approach identifying interventions that...

New materials contract when they should expand, expand when they should contract It's not magic, but new materials designed by two Northwestern University researchers seem to exhibit magical properties. Some contract when they should expand, and others expand when they should contract. When tensioned, ordinary materials expand along the direction of the applied force. The new metamaterials (artificial materials engineered to have properties that may not be found in nature) do the...

Ever wonder why your friends have more friends than you or diamond is harder than graphite? A new article by a Northwestern University complex networks expert discusses how networks governing processes in nature and society are becoming increasingly amenable to modeling, forecast and control. The article establishes relationships between seemingly disparate topics such as the friendship paradox -- by which our friends have on average more friends than we do -- and why carbon can result...

Research could rescue fragile ecosystems and halt complex cascade events In an effort to better understand the dynamics of complex networks, scientists have developed a mathematical model to describe interactions within ecological food webs. This research, performed by Northwestern University physics professor Adilson Motter and his student, Sagar Sahasrabudhe, is published in the January 25 issue of Nature Communications. The work illustrates how human intervention may effectively aid...

Gene therapy, in which a working gene is inserted into a cell to replace a faulty or absent gene, is a promising experimental technique for the prevention and treatment of disease. Now a research team led by a Northwestern University physicist reports that a counterintuitive approach also holds promise. The targeted removal of genes -- the exact opposite of what a gene therapist would do -- can restore cellular function in cells with genetic defects, such as mutations. Published online in the...


Word of the Day
barratry
  • The offense of persistently instigating lawsuits, typically groundless ones.
  • An unlawful breach of duty on the part of a ship's master or crew resulting in injury to the ship's owner.
  • Sale or purchase of positions in church or state.
This word ultimately comes from the Old French word 'barater,' to cheat.
