Mojave sandy desert habitat in Fall (November)
Intense summer temperatures are beginning to cool down by November, but most vegetation has gone dormant due to the extreme heat and low levels of rainfall.
Mature and healthy forest area
Forests are lively ecosystems that need fires to function. Dead plants and animals on the forest floor are fuel for fires.
Lemmings are small animals who show a flux in population every few years. Numbers become low when predators over-hunt the lemmings. Numbers of lemmings skyrocket when food is plentiful-lemmings reproduce very quickly. When there are too many lemmings in one area, they fight for space and food. Many of them die from starvation and the numbers of lemmings plummet once again.
The iris is the colored part of the eye. The pupil is the dark circle in the middle of the iris. The iris causes the pupil to expand or contract depending on the amount of light in a given area. Once light passes through the pupil, a structure called the lens that is directly behind the pupil focuses the light at the back of the eye. The optic nerve, located at the back of the eye, takes the focused message and relays it to the brain where it is processed into an image.

MODIS Snow Cover over North America
The Moderate Resolution Imaging Spectroradiometer (MODIS) provides data in 36 spectral bands, some of which are used in an algorithm to map global snow cover. In this animation, a time series of global snow cover from MODIS-derived 8-day composite snow maps with a spatial resolution of about 5 km shows the dynamic behavior of the advance and retreat of continental snow cover over North America during the winter of 2001-02.
Daily Snow and Sea Ice Temperature over Asia
This animation shows the global advance and retreat of daily snow cover along with daily sea ice surface temperature over Asia from September 2002 through May 2003. The snow cover was measured by the MODIS instrument on the Terra satellite, while the sea ice surface temperature was measured by the MODIS instrument on the Aqua satellite. Since these instruments cannot take measurements through clouds, in cloud-covered regions or areas with suspect data quality, the prior days value is retained un

Gene Stories: The Court of Opinion
Part of a BBC Web site devoted to demystifying the world of genes, the Court of Opinion offers users a fun, interactive way to explore some of the ethical issues raised in the field of genetic research. Users step into a virtual courtroom to hear from "the scientists, the campaigners, the advocates and the voices of dissent." Three courtrooms are available, each focused on a different issue, such as the relative contribution of nature (our genes) versus nurture (our environments) to human behavi
