  ESO Sub-Millimeter Astronomy Fully Underway
This particular wavelength is very difficult to investigate, ESO explained in its news release, both because the water vapor in Earth's atmosphere attenuates the signal even more severely than elsewhere in the submillimeter range, but also because it is at the limit of the telescope's operating range.
Millimeter and sub-millimeter astronomy opens possibilities in the study of the first galaxies to have formed in the universe and of the formation processes of stars and planets.
It also allows astronomers to study the chemistry and physical conditions of molecular clouds, that are dense regions of gas and dust in which new stars are forming.

  UW physicists find that extra dimensions must be smaller than 0.2 millimeter
A new development in that theory suggests that gravity's apparent weakness could be caused by a unique property allowing gravity to leak off into "extra" dimensions, while everything else is confined to the normal dimensions of length, width and height.
The UW team recently measured the strength of gravity at a distance of just 0.2 millimeter and found no deviation from the gravitational pull predicted by the inverse-square law devised by Isaac Newton.
The research team already is fabricating equipment to test to 0.1 millimeter or less, and has begun planning an experiment to test at even smaller distances.

 MILLIMETER WAVE ROTMAN LENS OFFERS INEXPENSIVE, RUGGED, RELIABLE & COMPACT ELECTRONICALLY-SCANNED ANTENNA
The device got its name because of its ability to focus microwave or millimeter wave energy coming from a particular direction by passing the electromagnetic energy through a pair of parallel plates that are shaped like a lens.
Most antennas operating at millimeter wave frequencies use mechanical scanning or phase shifters, both of which have disadvantages.
A synthetic vision system based on millimeter wave radar could produce images through the fog, allowing aircraft to land even when runways are obscured.

 Laboratory for Millimeter-wave Astronomy
The Laboratory for Millimeter-Wave Astronomy (LMA) is an organization set up within the Department of Astronomy to manage Maryland's 20% participation in the Berkeley Illinois Maryland Array (BIMA), a millimeter-wave radio array in Hat Creek, California.
The LMA group is interested in understanding the basic physical properties of star forming regions in our own and nearby galaxies, the properties of the interstellar medium in general, galactic dynamics and the overall structure of the Milky-Way, and external galaxies.
They primarily use millimeter transitions in the low lying levels of simple molecules like CO and the very good spatial resolution available with BIMA (0.5 arcsec) to study the morphology and dynamics of molecular clouds, which are thought to be stellar nurseries and a tracer of the galactic disk.

 Filmtracks: Eight Millimeter (Mychael Danna)
Eight Millimeter includes the same unique style of combining soft instrumental solos with boisterous and occasionally overwhelming sequences of a native Arabic and North African motif.
Although hinting at the native North African music in small portions previously, the film's shift of setting to Hollywood is announced by a sudden and extremely heavy Moroccan influence.
The short and enjoyable sequences of soft, reflective cues in Eight Millimeter are overshadowed by the harsh and loud Moroccan music that dominate such long tracks as eight, ten, sixteen, and eighteen.

This portion of the spectrum, which is more energetic than most radio waves yet less energetic than visible and infrared light, holds the key to understanding a great variety of fundamental processes, including planet and star formation, and the formation and evolution of galaxies and galaxy clusters in the early Universe.
The millimeter and sub-millimeter radiation that ALMA will study is able to penetrate the vast clouds of dust and gas that populate interstellar and intergalactic space, revealing previously hidden details about astronomical objects.

The nature of emission from solar flares at millimeter wavelengths is discussed.
In the impulsive phase of flares, millimeter emission should be dominated by gyrosynchrotron emission from MeV--energy electrons.
Millimeter telescopes are very sensitive to these electrons and can make high--resolution images of their sources for comparison with HESSI images, allowing us to investigate the behaviour of electron acceleration across a wide range of energies.

 Physics Today - Physics Community
The spectrum reallocations, agreed to this past May at the monthlong World Radiocommunications Conference (WRC) in Istanbul, Turkey, were the most extensive since 1979--when those high frequencies were still untapped by both science and the commercial satellites whose emissions can drown out the fainter signals radio astronomers look for.
"The millimeter spectrum is the El Dorado of molecular line spectroscopy," adds Klaus Ruf, who chairs IUCAF, the International Council for Science committee that deals with frequency allocations for radio astronomy and space science.
The increased protection is good news for projects such as the US­European Atacama Large Millimeter Array (ALMA) being built in Chile and the US­Mexican Large Millimeter Telescope under construction in Mexico.
