Saving Seahorses
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

Our Changing Climate
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. Tropical highlands and

Spring Flowers: Clues To Climate Change
Researchers began a
nationwide initiative to
track climate change by
recording the timing of the
first bud, first flower, and
seed dispersal for plants
across the country. They

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

Soil Scientists Restore Marshes To Protect Coastal Ecology
Soil scientists spread material dredged from shipping channels over shore areas to help rebuild marsh areas. Wetlands along the shore protect the land from storm surges, create habitat for wildlife, ... > more -
Statisticians Show that High Altitude Makes Hits Longer
Two mathematicians at the University of Northern Colorado are taking a fresh statistical look at the effects of elevation on hitting -- specifically at Coors Field in Denver, where the field is at a ... > more -
Scientist Measures Land Used by Lawns
Using census data, satellite images, aerial photographs, and computer simulations, a NASA scientist estimated that turf grass is the single-largest irrigated crop in the United States, three times ... > more -
Disaster Experts Map Risk Across the Nation
Disaster experts including meteorologists and seismologists have identified the types of catastrophic events the United States is most likely to face, quantifying the risk of earthquakes, urban ... > more -
Seismologists Find Large Earthquakes Can Trigger Smaller Ones In Unlikely Locations
Seismologists found that L-waves, slow-moving seismic surface waves, from larger earthquakes can trigger smaller earthquakes as they travel through the ground. Different from aftershocks because ... > more -
Physicist Explains Benefits Of Carbon Dioxide
A physicist from Colorado State University and his colleagues from the North American Carbon Program (NACP) have discerned and confirmed the unforeseen advantages of rising carbon dioxide levels. ... > more -
New Software Helps Track the Path of Toxic Spills
Ecological engineers have developed software that can model the path of a toxic spill in waterways anywhere in the United States. The system can predict if and when a contaminant will reach a ... > more -
Ecologists Deploy Wireless Sensors for Early Detection of Wildfires
New fire-sensing devices can spot a fire in its earliest stages, up to six miles away, and they can relay the information to emergency responders through a computer network and even automatically ... > more -
Oceanographers Uncover The Physics Of Rip Currents
Rip currents flow in very erratic patterns, not in steady courses as previously believed -- which may help explain why they can be so dangerous even for experienced swimmers. Oceanographers have ... > more -
Meteorologists Track Tornado Damage From Satellites
Meteorologists use high resolution satellite photography to analyze the path and intensity of recent tornadoes. The data obtained allows them to develop a mathematical model to identify storm damage ... > more
