Blooming prickly pear cactus (Opuntia) from the Sonora desert
Cacti are often overlooked as flowering plants. In fact, cacti bloom with colorful flowers and reproduce like all other angiosperms.
Blood flow of moving Lumbriculus
Observe blood flow and muscle contractions in each body segment of Lumbriculus variegates (note how blood flows in relation to the worm turning in the capillary tube).
Blood circulation through zebrafish
Lateral and tail view of developing Danio showing blood flow to and from the tail section.
Aquatic Animal Skeleton - Backbone
The backbone of an aquatic animal allows it to be very flexible under water. It usually extends into a tail and is classified as a gliding joint.
Fly on a leaf
Flies are insects that eat dead plant and animal material. Their ingestion and digestion of detritus leads to respiration and excretion of important nutrients back into the soil and water.
Celery in pure water
The celery stalks take up the water and continue to live in this environment.
Root behavior
Roots can grow in multiple directions. Just because this plant was in a cup didn't stop the roots from growing longer and creating individual branches.
The San Joaquin kit fox
San Joaquin kit foxes are nocturnal and hunt small mammals at night. They make dens and stay in them during the day to conserve water and energy.

AMSR-E Anomalous Atlantic Sea Surface Temperature Data Used to Forecast 2003 Hurricane Season 1
Researchers and forecasters often study sea surface temperatures for an indication of hurricane potential. Scientists say above normal Atlantic Ocean temperatures is one reason for the "above normal" hurricane forecast. Hurricanes convert heat from the tropical atmosphere and oceans to wind and waves, just as a car engine converts gasoline into motion. These animations show a year in the life of global ocean temperatures, June 2, 2002 to May 11, 2003. Green indicates the coolest water, yellow th
EPTOMS Ozone (7-26-96 - 12-4-00)
This animation shows the total ozone as measured by Earth Probe TOMS since the earliest measurements by that instrument. Days on which no data was taken appear as blank.

Biomass Burning over South America
Biomass burning is the burning of living and dead vegetation. It includes the human-initiated burning of vegetation for land clearing and land-use change as well as natural, lightning-induced fires. Scientists estimate that humans are responsible for about 90% of biomass burning with only a small percentage of natural fires contributing to the total amount of vegetation burned. Burning vegetation releases large amounts of particulates (solid carbon combustion particles) and gases, including gree
Antarctic Ozone from Earth Probe TOMS: July 25, 1999 through September 25, 1999
Total ozone measurements from Earth Probe TOMS over Antarctica for the period July 25, 1999 through September 25, 1999
Solar Cells
Advanced semiconductor devices are a new source of energy for the 21st century, delivering electricity directly from sunlight. Suitable semiconductor materials, device physics, and fabrication technologies for solar cells are presented in this course. The guidelines for design of a complete solar cell system for household application are explained. Cost aspects, market development, and the application areas of solar cells are presented.
Aircraft Systems Engineering, Fall 2003
Aircraft are complex products comprised of many subsystems which must meet demanding customer and operational lifecycle value requirements. This course adopts a holistic view of the aircraft as a system, covering: basic systems engineering; cost and weight estimation; basic aircraft performance; safety and reliability; lifecycle topics; aircraft subsystems; risk analysis and management; and system realization. Small student teams "retrospectively analyze" an existing aircraft covering: key desi
Space Systems Engineering, Spring 2002
Space Systems Engineering (16.83X) is the astronautical capstone course option in the Department of Aeronautics and Astronautics. Between Spring 2002 and Spring 2003, the course was offered in a 3-semester format, using a Conceive, Design, Implement and Operate (C-D-I-O) teaching model. 16.83X is shorthand for the three course numbers: 16.83, 16.831, and 16.832. The first semester (16.83) is the Conceive-Design phase of the project, which results in a detailed system design, but precedes assembl
What's at stake: Strait of Hormuz by the numbers
Jan. 5 - With millions of barrels of oil and oil product flowing through the Strait of Hormuz every day, Iran's threat to shut down traffic could have a big impact on world trade.
Demain, l’Université (audio)
L’étiolement en France de la conception d’une université comme unique lieu de production du savoir et d’échange, et la conséquente création des grandes écoles, organismes de recherche, IUT…, ont appauvri, en même temps que le sous-financement et le manque d’autonomie, l’université française.
Et demain ? L’université devra se construire autour des initiatives à venir. La loi de liberté et d’autonomie, dite loi Pécresse (LRU), sera un premier pas en avant car
Femmes et droit en Islam - Sana Ben Achour (video)
Le propos est de montrer comment, aujourd’hui, dans les pays de culture musulmane, notamment dans les pays du Maghreb, se réarticule, se construit et se noue autour de la réforme du statut personnel ou de la famille, un système de normativité où droit et religion, tradition et modernité, droits universels et spécificités culturelles et identitaires, sont en «équilibre transactionnel » (pour reprendre une formule chère à Jacques Berque). Il est donc important de retracer la gen
