New data to improve models of atmosphere circulation

A team of scientists from the Institute of Mechanics, MSU, demonstrated how random fluctuations in the rotation speed and noise influence the number of vortexes in the Couette spherical flow. They report that the level of ...

IT researchers break anonymity of gene databases

DNA profiles can reveal a number of details about individuals, and even about their family members. There are laws in place that regulate the trade of gene data, which has become much simpler and cheaper to analyze today. ...

Scientists predict activity of human genes

Genetically identical cells do not always behave the same way. According to the accepted theory, the reason are random molecular processes - known as random noise. For decades this view has been underpinned by numerous experiments ...

New frontier in error-correcting codes

Error-correcting codes are one of the glories of the information age: They're what guarantee the flawless transmission of digital information over the airwaves or through copper wire, even in the presence of the corrupting ...

Adhesion disturbed by noise

Imagine a solid ball rolling down a slightly inclined ramp. What could be perceived as child's play is the focus of serious theoretical research by Manoj Chaudhury and Partho Goohpattader, two physicists from Lehigh University, ...

Random noise helps make signals clearer

Scientists have shown the energy conditions, under which a weak signal supplied to a physical system emerges as a stronger signal at the output thanks to the presence of random noise (a process known as stochastic resonance), ...
