| SCI | Polarized Light Pollution Leads Animals Astray
Human-made light sources can alter natural light cycles, causing animals that rely on light cues to make mistakes when moving through their environment. In the journal Frontiers in Ecology and the Environment, a collaboration of ecologists, biologists and biophysicists has now shown that in addition to direct light, cues from polarized light can trigger animal behaviors leading to injury and often death.

| SCI | Powdered Rodents Show Big, Old Mice Spread Hantavirus
University of Utah researchers dusted wild deer mice with fluorescent pink, blue, green, yellow and orange talcum powders to show which rodents most often fought or mated with others and thus were most likely to spread deadly hantavirus. The study identified bigger, older mice as the culprits. (Embargo expired on 06-Jan-2009 at 19:00 ET.)

| SCI | Four, Three, Two, One . . . Pterosaurs Have Lift Off!
Pterosaurs have long suffered an identity crisis. Pop culture heedlessly — and wrongly — lumps these extinct flying lizards in with dinosaurs. Even paleontologists assumed that because the creatures flew, they were birdlike in many ways, such as using only two legs to take flight.

| SCI | Scientists Discover Dangerous New Method for Bacterial Toxin Transfer
Scientists have discovered a new way for bacteria to transfer toxic genes to unrelated bacterial species, a finding that raises the unsettling possibility that bacterial swapping of toxins and other disease-aiding factors may be more common than previously imagined.

| SCI | Star Light, Star Bright, Its Explanation is Out of Sight
This pair of NASA Hubble Space Telescope pictures shows the appearance of a
mysterious burst of light that was detected on February 21, 2006, brightened
over 100 days, and then faded into oblivion after another 100 days. The source
of the outburst remains unidentified. The event was detected serendipitously in
a Hubble search for supernovae in a distant cluster of galaxies. The light-signature
of this event does not match the behavior of a supernova or any previously
observed astronomical transient phenomenon in the universe.

| SCI | Can Nature’s Leading Indicators Presage Environmental Disaster?
Economists use leading indicators — the drivers of economic performance – to take the temperature of the economy and predict the future.
Now, in a new study, scientists take a page from the social science handbook and use leading indicators of the environment to presage the potential collapse of ecosystems. (Embargo expired on 05-Jan-2009 at 17:00 ET.)
