A group of British researchers recently carried out a study in which they emulated the processes through which DNA material inside living cells is damaged. They learned that the thickness of the membrane separating the cells from their environment plays a critical role in the process.
The work was carried out with ... |

Researchers at the University of California in Los Angles (UCLA) have recently determined how the HIV TAT cell-penetrating peptide is capable of breaching cellular defenses in order to deliver its cargo. The findings could be used to create highly-advanced, molecular drug delivery systems.
At this point, an import... |

Experts in the field of structural biology are proud to announce a momentous achievement in their area of expertise. Colleagues from an international research group were recently able to use the world's first free electron laser (FEL) to capture an image of an intact virus. In addition to viewing the tiny microo... |

Light-controlled membranes represent a concept that is so advanced it hasn't even made its way into science-fiction literature. Nevertheless, they are now a reality, thanks to a study conducted by investigators at the University of Rochester. The group managed to create membranes which allow or prevent gas from ... |

Interactions at a cellular level are the things that drive all living things, according to biologists. All cells need to be able to communicate with the outside world, and the way they do that is by exchanging chemicals through their membranes. Regardless of whether we're talking about a brain cell or a single-c... |

Scientists from the University of Utah have recently announced the creation of a new method of assessing the quality of the water that astronauts drink in orbit. While, at first glance, the process may seem similar to what goes on down on Earth, this is not the case. For example, aboard the International Space Statio... |

For many years, experts have tried to gain a better understanding of cancer, of why it appears, and of how it spreads through the human body. In order to do this, they need to be able to observe and to control interactions that occur within a cell, especially at the individual protein level. Recently, breakthroughs h... |
