Secret of efficient photosynthesis: Purple bacteria's light-harvesting prowess lies in highly symmetrical molecules
Purple bacteria are among Earth's oldest organisms, and among its most efficient in turning sunlight into usable chemical energy. Now, a key to their light-harvesting prowess has been explained through a detailed structural ...
Mathematical analysis helps untangle bacterial chromosomes
When an E. coli cell divides, it must replicate its circular chromosome and pull the resulting circles apart to take up residence in two new cells. It sounds easy enough—like a magician's trick with rings—but actually involv ...
Japanese robot to sit top-ranked university exam
Japanese researchers are working on a robot they hope will be smart enough to ace entrance exams at the nation's top university, which test everything from maths to foreign languages.
The mathematics of jury size: Statistical model shows several interesting properties of US jury configurations
Could different jury sizes improve the quality of justice? The answers are not clear, but mathematicians are analyzing juries to identify potential improvements.
Hairpin turn: Micro-RNA plays role in wood formation
For more than a decade, scientists have suspected that hairpin-shaped chains of micro-RNA regulate wood formation inside plant cells. Now, scientists at NC State University have found the first example and mapped out key ...
Genetic similarity promotes cooperation
In a dog-eat-dog world of ruthless competition and 'survival of the fittest,' new research from the University of Leicester reveals that individuals are genetically programmed to work together and cooperate ...
Maths experts question key ecological theory
Mathematicians at the University of York in the UK and the University of Canterbury in New Zealand say they have disproved a widely accepted theory underpinning the operation of complex networks of interactions in the natural ...
Mighty mesh: Extracellular matrix identified as source of spreading in biofilms
New research at Harvard explains how bacterial biofilms expand to form slimy mats on teeth, pipes, surgical instruments, and crops.
Astronomy without a telescope: The unlikeliness of being
History has proved time and again that mathematical modelling is no substitute for a telescope (or other data collection device). Nonetheless, some theoreticians have recently put forward a statistical analysis ...
Predicting burglary patterns through math modeling of crime
Pattern formation in physical, biological, and sociological systems has been studied for many years. Despite the fact that these subject areas are completely diverse, the mathematics that describes underlying patterns in ...
You clap, so I clap: Peer pressure drives applause
If you have just seen a play that you privately think is drivel, will you keep silent when everyone around you demands an encore?
