University of Michigan (U-M) investigators say that they are currently developing improved, portable gas sensors. The devices will be used to sniff out markers indicating the presence of explosives, diagnose diseases by analyzing breath, and detect accumulations of dangerous chemicals.
Such sensors have been around ... |

A group of physics experts from the Massachusetts Institute of Technology (MIT), in Cambridge, has recently created clouds of gas that cannot pass through each other. Achieving this with a cloud of chemicals about 1,000 times thinner than air is a tremendous feat of ingenuity. Generally, when two clouds of normal gas... |

Experts in the field believe that the future of gas detectors lies within a new generation of optical sensors, which are apparently able to detect trace amounts of harmful chemicals in the air with ease. The new systems, their designers say, could be employed in the near future in a wide array of applications, rangin... |

Discovering dead bodies at accident scenes, disaster sites, and in graves hastily dug up by murderers is, at this point, a painstaking process, revolving mostly around a trial-and-error methodology. Some people who survive an earthquake, for instance, die under the rubble, but they cannot be found even after their de... |

Most people believe that traffic jams happen only when an accident occurs, or when a long line of cars reaches a bottleneck. Under these circumstances, the traffic naturally slows down or stops completely, but these are not the only things that cause jams. Scientists are currently studying a phenomenon called “... |

Scientists are currently puzzled by a new find, which shows that ash and gas plumes, fresh of a volcano, behave in very much the same way as tornadoes do, during the peak of their season. In addition to spawning dust devils, large concentrations of ash and other gases can also create lightnings in the clouds above, a... |

After numerous warnings, in the form of tremors and increased pressure in its magma chamber, Mount Redoubt in Alaska erupted four times last night, sending plumes of ash and gases more than 9 miles high into the atmosphere. The events took place between 10:38 pm on Sunday evening and 1:39 am on Monday morning, local ... |

Off the coast of the South Pacific Kingdom of Tonga, a cluster of more than 36 volcanoes has formed right below the surface of the sea. On Monday, one of them began to erupt with such a force that it sent ashes and gas thousands of feet into the atmosphere, prompting the immediate dispatch of a science team on locati... |

Measuring noise levels and composition right before a volcano erupts is a very tricky and risky business, mostly because the scientists have to work on the slopes of the mountain themselves, as they cannot leave the equipment behind, and then recover it later. The reason for that is pretty obvious – the sound r... |

Astronomers now believe they may have found the answer to a very old question in the field – how were huge early galaxies able to create massive amounts of stars without devouring each other to gain matter? The answer may lie within the mysterious dark matter, which researchers now say helped channel gas from a... |

A physics theory states that molecular chaos is an assumption that the velocities of colliding particles are uncorrelated and independent of position. Also called collision number hypothesis, it is useful in making numerous calculations tractable, but so far no one was able to experimentally prove it.Air in any room... |
