NASA sees remnants of Nilofar go to cyclone graveyard

( NASA/Goddard Space Flight Center) Wind shear has caused the demise of former Tropical Cyclone Nilofar in the northern Arabian Sea. NASA's Aqua satellite passed over Nilofar on Oct. 31 and captured an image that shows strong wind shear has pushed the bulk of clouds and showers away from Nilofar's center, basically sending the storm to its grave.

Viewing cancer on the move: New device yields close-up look at metastasis

( Johns Hopkins University) Johns Hopkins engineers have invented a lab device to give cancer researchers an unprecedented microscopic look at metastasis, the complex way that tumor cells spread through the body, causing more than 90 percent of cancer-related deaths.

A new generation of storage -- ring

( International Union of Crystallography) The MAX IV facility, currently under construction in Lund, Sweden, is the first of a new generation of storage-ring-based synchrotron light sources which employ a multibend achromat lattice to reach emittances in the few hundred pm rad range in a circumference of a few hundred meters.

Tropical Depression Nuri now haunting the western Pacific Ocean

( NASA/Goddard Space Flight Center) Tropical Depression Nuri formed on Halloween morning, Oct. 31, and is haunting the waters of the western North Pacific Ocean. NASA-NOAA's Suomi NPP satellite captured a ghostly-white image of the storm.

Raising cryptography's standards

( Massachusetts Institute of Technology) Calculating encryption schemes' theoretical security guarantees eases comparison, improvement.

Tropical Storm Vance's center looks like a pumpkin to NASA's Terra satellite

( NASA/Goddard Space Flight Center) Tropical Depression 21E strengthened overnight on Oct. 30 and by Halloween morning, Tropical Storm Vance was haunting the waters of the Eastern Pacific Ocean. In a false-colored infrared image from NASA's Terra satellite on Oct. 31, the strong thunderstorms around the center resemble a pumpkin.

Ant behavior might shed insight on problems facing electronics design

( Virginia Tech) The National Science Foundation has awarded Michael Hsiao, professor of electrical and computer engineering at Virginia Tech, a grant of $418,345 to improve the accuracy in electronics design, using algorithms he designed that simulate ant behavior.

Tweet much to gain popularity is an inefficient strategy

( FECYT - Spanish Foundation for Science and Technology) The imbalanced structure of Twitter, where some users have many followers and the large majority barely has several dozen followers, means that messages from the more influential have much more impact. Less popular users can compensate for this by increasing their activity and their tweets, but the outcome is costly and inefficient. This was confirmed by an analysis of the social network performed by researchers from the Technical University of Madrid.

Captive rhinos exposed to urban rumbles

( Acoustical Society of America) The soundtrack to a wild rhinoceros's life is wind passing through the savannah grass, birds chirping and distant animals moving across the plains. But a rhinoceros in a zoo listens to children screaming, cars passing and the persistent hum of urban life. A group of researchers from Texas believes that this discrepancy in soundscape may be contributing to rhinos' difficulties thriving and reproducing in captivity.

MINER shines in urban emergency response exercise

( DOE/Sandia National Laboratories) In a field test in downtown Chicago, Sandia National Laboratories' mobile imager of neutrons for emergency responders (MINER) system identified the exact location of a sealed laboratory radiation source through shielding and at a distance. MINER detects fast neutrons that emanate from special nuclear material and can discriminate the device signature from background radiation and to measure the spectrum of neutrons emitted by it.
