Virtual laboratory predicts train vibrations
The construction of new rail lines, or the relocation of old ones underground, has increased society's interest over recent years in the vibrations produced by trains, especially among people who live or work ...
Researchers use cell 'profiling' to detect abnormalities -- including cancer
An Ohio State University mathematician and his colleagues are finding ways to tell the difference between healthy cells and abnormal cells, such as cancer cells, based on the way the cells look and move.
Korean researchers reveal new sea defense model
Military tension between North Korea and the Republic of Korea (South Korea) extends to areas of the Yellow Sea. Now defence experts based in the Republic of Korea have devised improved methods to model underwater warfare, ...
How the sun gets its spots
Sunspots are huge, dark, irregularly shaped--and yet, temporary--areas of intense magnetism on the sun that expand and contract as they move.
Mathematical model shows how groups split into factions
(PhysOrg.com) -- The school dance committee is split; one group wants an "Alice in Wonderland" theme; the other insists on "Vampire Jamboree." Mathematics could have predicted it.
Cassini marks holidays with dramatic views of Rhea
(PhysOrg.com) -- Newly released for the holidays, images of Saturn's second largest moon Rhea obtained by NASA's Cassini spacecraft show dramatic views of fractures cutting through craters on the moon's surface, ...
Quantum or not? Mathematical equations resolve nanostructures behavior
Understanding the transport of electrons in nanostructures and biological molecules is crucial to understanding properties such as electrical conductivity or the biochemical behavior of molecules. However, ...
How Iapetus got its ridge
For centuries, people wondered how the leopard got its spots. The consensus is pretty solid that evolution played a major role.
Jupiter gets its stripe back
(PhysOrg.com) -- Astronomers using three telescopes atop Mauna Kea in Hawaii have recorded the return of a unique belt on Jupiter that periodically fades from dark brown to white. It's most recent fade-out ...
New equation calculates cost of walking for first time
Why do tall people burn less energy per kilogram when walking than shorter ones do, and how much energy does walking require? These are basic questions that doctors, trainers, fitness buffs and weight-watchers would all like ...
Climate change may create tipping points for populations, not just species
(PhysOrg.com) -- As Earth's climate warms, species are expected to shift their geographical ranges away from the equator or to higher elevations.
New equation could advance research in solar cell materials
(PhysOrg.com) -- A groundbreaking new equation developed in part by researchers at the University of Michigan could do for organic semiconductors what the Shockley ideal diode equation did for inorganic semiconductors: ...
Quarks 'swing' to the tones of random numbers
At the Large Hadron Collider at CERN protons crash into each other at incredibly high energies in order to 'smash' the protons and to study the elementary particles of nature - including quarks. Quarks are ...
Unraveling the Matrix
A new way of analyzing grids of numbers known as matrices could improve signal-processing applications and data-compression schemes.
