Many of the body's cells need a reliable flow of potassium to perform their daily tasks. One key to potassium flow, now revealed to researchers, appears to be the energetic effect of a pool of approximately 50 water molecules and four protein spirals that sit in the middle of a narrow channel embedded within cell membranes.

US researchers have created 'bacterial computers' with the potential to solve complicated mathematics problems. The findings of the research demonstrate that computing in living cells is feasible, opening the door to a number of applications. The second-generation bacterial computers illustrate the feasibility of extending the approach to other computationally challenging math problems.

Plastic surgeons are turning to mathematics to take the guesswork out of efforts to ensure that live tissue segments that are selected to restore damaged body parts will have enough blood and oxygen to survive the surgical transfer.
In the world’s first published mathematical model of tissue transfer, mathematicians have shown that they can use differential equations to determine which tissue segments selected for transfer from one part of the body to another location on the same body will receive the level of oxygen required to sustain the tissue.

A math-based game that has taken the world by storm with its ability to delight and puzzle may now be poised to revolutionize the fast-changing world of genome sequencing and the field of medical genetics, suggests a new report by a team of scientists at Cold Spring Harbor Laboratory (CSHL). The report will be published as the cover story in the July 1st issue of the journal Genome Research.
Combining a 2,000-year-old Chinese math theorem with concepts from cryptology, the CSHL scientists have devised "DNA Sudoku." The strategy allows tens of thousands of DNA samples to be combined, and their sequences – the order in which the letters of the DNA alphabet (A, T, G, and C) line up in the genome – to be determined all at once.
