Sounds From the Sea
Manmade and natural sounds,
from boat engines to
rainfall, sound different
below the sea surface. To
study their impact of noise
on marine life, scientists
are submerging devices
called Passive Aquatic

Right Mix Of Trees Fights Global Warming
A research team found 31
hardy trees that sequester
carbon efficiently for the
New York region, mitigating
against the impacts of high
deforestation and carbon
release into the atmosphere

Climatologists Forecast Completely New Climates
Geographers have projected temperature increases due to greenhouse gas emissions to reach a not-so-chilling conclusion: climate zones will shift and some climates will disappear completely by 2100. ... > more -
Architectural Engineers Design Homes To Withstand Earthquakes
Engineers have designed windows and walls that will not break when shaken by the intense motion caused by earthquakes. By installing glass panels that do not touch the corners of the frame, ... > more -
Marine Biologists Work To Protect Seahorses By Developing A Breeding Program
Marine biologists, worried that regular harvesting of wild seahorses may threaten the creature with extinction, have begun breeding them in home aquariums. Caring for seahorses requires a three-step ... > more -
Meteorologists Use Weather Knowledge to Predict Path of Toxic Spills
Homeland security officials are tapping researchers' capability to predict the paths of toxic waste spills and hazardous airborne particles. Using computer science and mathematics, along with ... > more -
Soil Scientists Restore Marshes To Protect Coastal Ecology
