Mars to Earth hearing Mars sounds on Polar Lander mission
UC Berkeley scientists plan a microophone on the Mars Polar Lander set for 1999 to record natural Martian sounds. The project, funded by The Planetary Society, aims to gauge public interest in extraterrestrial exploration while testing rugged, lightweight gear for 10 second sound bursts on approach and beneath the ice cap.

Climate-driven shifts reshape forest migration patterns
Ecologists note past forest migrations moved entire communities in response to climate shifts, but human fragmentation of landscapes now blocks or reshapes these movements. Trees and understory species may struggle to keep pace with rapid warming, while weeds could outrun others in disturbed ground, forcing a grand reshuffling of temperate ecosystems.

Climate driven forest migration faces barriers from fragmentation
Ecologists say temperate zone trees could migrate north as climate warms. Wind, water, birds, and mammals transport seeds but farms, roads, and development slow movement. Emerging long leaps and seed dispersal models offer partial explanations. fragmentation reduces open habitat and creates barriers to spread. Dr James S Clark of Duke University notes non forested areas diminish landing sites for long distance colonists and threaten forest floor plants.

Flamingos in Florida ponds aid bird attraction study
Researchers in Florida paint 150 lawn flamingos white and place them in Everglades ponds to test whether the presence of decor affects wood storks and white ibises as pond depth and fish supply are varied. The project seeks to understand social attraction factors in declining species.

Praesepe Beehive Star Cluster in Cancer Sky Watch
Sky watch report notes the Beehive star cluster in Cancer, also called Praesepe, rising toward the south during mid-evening. It explains historical names and the cluster's visibility, with binoculars showing over 100 stars and maps timed for 9:00 pm Sunday, 6:08 pm and 8:30 pm accuracy.

Beer stored hot worsens taste via acetaldehyde buildup
Researchers at the University of California Davis measured how temperature accelerates acetaldehyde formation in beer. Bottled samples stored above 120 degrees Fahrenheit showed a drastic rise, with tasters noting an off flavor and the beer containing 873 percent more acetaldehyde than fresh.
