As experts begin to probe the issues raised by a potential trip to Mars in more depth, they start realizing that the actual flight itself and the problems related to constructing a proper vehicle to get there and back are only minor, in comparison to other issues. One of the problems is how nearly two years of co... |

A team of German scientists has recently announced the development of a new, blood-analysis instrument, which is able to detect pathogens without the use of markers. The technology is very compact, and can be used in hospital settings, as well as in mobile transfusion units and blood-donation clinics. Results from th... |

According to new scientific evidence, it would appear that the retroviruses from which the Human Immunodeficiency Virus (HIV) evolved have been plaguing the animal world since 100 million years ago. The new time frame is about 85 million years 'older' than first thought, which brings into focus the need to ... |

Experts from the US Department of Energy's (DOE) Pacific Northwest National Laboratory (PNNL) have recently developed a new series of structures, constructed entirely out of the relatively new carbon compound graphene and strands of DNA, which is the building block of all living things. The team, which worked cl... |

As we pointed out earlier, the state of the “war” between microorganisms and humans is getting increasingly worrying for our species. In spite of being more complex in make-up than bacteria – or maybe because of that –, we cannot adapt very fast to their mutations, and our immune systems just ... |

Perhaps the greatest problem with treatments available today for most conditions is the fact that they address the symptoms and not the root causes of the conditions. Analyzing the interactions of proteins, which occur at very tiny scales, scientists need powerful observational tools. However, not even the most advan... |

Most viruses that are able to infect the human body, as well as other animals, require living cells in order to replicate and create more viral agents. However, they also need specific chemicals and proteins located inside these cells, without which their replication cycle cannot be started. Researchers have, for ins... |

A newly bioengineered peptide nanoparticle has the ability to pass through the blood-brain barrier and provide localized care to brain regions affected by meningitis, as well as by other antibiotics-resistant bacteria and pathogens. The breakthrough, accomplished by experts at the Institute of Bioengineering and Nano... |

As some homeowners can attest to, termite infestation is one of the worst things that could happen to the place, other than floods, earthquakes and wildfires. The insects are insanely hard to get rid of, and can bring structures a few thousand times their size down in a matter of months. In their nests, which are dam... |

Talking about perfect timing. Researchers at the North Carolina State University (NC State) and the Korea Advanced Institute of Science and Technology (KAIST) have just recently finished developing a new numerical model, designed to predict people's mobility and interaction patterns. The invention could be of tr... |

Over the past century, the influenza virus has wreaked havoc in the human population all around the world, while at the same time leaving experts unable to devise a comprehensive cure to kill it off. Because of its unique structure, the viral agent can easily mutate, and does so from one season to the next, making th... |
