New approach eliminates software deadlocks using discrete control theory
Software deadlocks are the Catch-22s of the computer world. These common bugs can freeze the machine when different parts of a program end up in an endless cycle of waiting for one another as they access shared data. view more (2008-12-02)
The ecological equivalent of Ellis Island: from ancestry to biodiversity
For many ecologists, the start of the 21st century was bewildering due to a book by Steve Hubbell. Hubbell claimed that many patterns in nature could be explained by a simple theory stating that all species are equivalent in competition for resources. In a letter to Ecology Letters, Rampal Etienne and Han Olff from the University of Groningen in... view more... (2004-02-24)
For some species, an upside to inbreeding
Although breeding between close kin is thought to be generally unfavorable from an evolutionary standpoint, in part because harmful mutations are more easily propagated through populations in this way, theory predicts that under some circumstances, the benefits of inbreeding may outweigh the costs. view more (2007-02-06)
Vanquishing infinity
Quantum mechanics and Einstein's theory of general relativity are both extremely accurate theories of how the universe works, but all attempts to combine the two into a unified theory have ended in failure. view more (2009-08-18)
Selection of the fittest
A new study shows that schools and many education programmes are failing to provide students with a basic understanding of evolution. It is famously difficult to explain evolutionary principles without resorting to anthropomorphic or figurative language. Evolution 'selects' the fittest individuals; species 'adapt' to change. Both of these phrases... view more... (2002-03-18)
The theory of the chaos against the corrosion
In the modern science the word "chaos" is used for the description of systems, behaviour of which seems quite random. However, mathematical modeling methods aid to find an inner order in they. A deterministic chaos theory that allows predictions of physicochemical and even biological processes was developed for the description of complex systems. view more (1999-08-24)
Invitation to the Media - String virtuosos gather in Oxford - 1st International Conference on String Phenomenology
Next week the University of Oxford is hosting a meeting of string experts - not in this case well-known musicians, but internationally renowned scientists. The meeting will bring together physicists who are striving to develop a consistent theory of the nature of matter - in other words, the basic building bricks of ourselves and the Universe we... view more...

APPLYING SHEWHART'S CONTROL CHARTS TO CLINICAL GOVERNANCE (p 463)
A theory of variation used for quality control in the manufacturing industry since the 1920s could have helped in the earlier detection of recent UK health crises, suggest authors of an article in this week's issue of THE LANCET. The physicist and engineer Walter Shewhart devised a simple graphical method based on mathematical theory and practical... view more... (2001-02-07)
Ancient neutrinos could put string theory and quantum loop gravity to the test
Tiny but ageing neutrinos can be used to test the very foundations of quantum theory at unprecedented cosmological time scales. view more (2005-10-14)
MU Researcher Investigates the Basis of Einstein's First Approximation in the Theory of Relativity
In his discussion of accelerated motion on page 60 of The Meaning of Relativity, Albert Einstein made an approximation that allowed him to develop the theory of relativity further. view more (2009-07-16)
Live fast, die young? Maybe not
The theory that a higher metabolism means a shorter lifespan may have reached the end of its own life, thanks to a study published in the journal Physiological and Biochemical Zoology. The study, led by Lobke Vaanholt (University of Groningen, The Netherlands), found that mice with increased metabolism live just as long as those with slower... view more... (2009-03-10)
Why the brain has 'gray matter'
By borrowing mathematical tools from theoretical physics, scientists have recently developed a theory that explains why the brain tissue of humans and other vertebrates is segregated into the familiar "gray matter" and "white matter." view more (2006-01-12)
A tiny, tunable well of light, and a string theorist's toolbox
Photonics, the science of using photons to carry information, promises to continue improving a wide variety of technologies, from computing to high-speed communication. view more (2009-09-21)
Oregon theory may help design tomorrow's sustainable polymer
Tomorrow's specialty plastics may be produced more precisely and cheaply thanks to the apparently tight merger of a theory by a University of Oregon chemist and years of unexplained data from real world experiments involving polymers in Europe. view more (2008-12-11)
Why do some queen bees eat their worker bee's eggs?
Worker bees, wasps, and ants are often considered neuter. But in many species they are females with ovaries, who although unable to mate, can lay unfertilized eggs which turn into males if reared. view more (2006-12-05)
HIV's effect on white blood cells questioned by new research
Scientists have refuted a longstanding theory of how HIV slowly depletes the body's capacity to fight infection, in new research published today. view more (2007-05-22)
Mathematics reveals genetic pattern of tumor growth
Using mathematical theory, UC Irvine scientists have shed light on one of cancer's most troubling puzzles - how cancer cells can alter their own genetic makeup to accelerate tumor growth. view more (2007-06-25)
Coexistence of identical competitors: an old doctrine challenged
An illustrious principle in ecology states that no two identical species may coexist: sooner or later all but one will drift to extinction. Researchers from the Beijing Normal University and the University of Helsinki have modeled recent data on fig-pollinating wasps that appear to contradict the old theory. The model, which is reported in a... view more... (2004-02-24)
What is time?
The concept of time is self-evident. An hour consists of a certain number of minutes, a day of hours and a year of days. But we rarely think about the fundamental nature of time. view more (2005-04-13)
Acoustic noise contains valuable information
The proper processing of acoustic noise can provide a wealth of information. Geophysicists have used seismic background noise measurements to reconstruct the crustal structure under Southern California. view more (2006-12-08)
