This module links human aggressive behavior with specific regions of the brain. Scenes from classic experiments show stimulation of a bull’s brain to stop it from charging and excitation of a cat’s hypothalamus to trigger aggression. A striking case of violent human behavior is then linked to a brain lesion — the surgical removal of which restored normal emotional control.

Takes us to the Sumerian archaeological sites in present day Iran, Iraq, Syria, and elsewhere, to see the influence of cuneiform, the oldest known writing system in the world. Its development brought about a cultural renaissance,and Sumers rise in the Mesopotamian region. The influence of these Sumerian wedge characters did not end with the fall of Sumer, but also provided a literary foundation for civilizations that followed. Cuneiform influenced Akkadian, Assyrian, Babylonian, and Persian writing, evolving over time from rudimentary pictures to standardized symbols. (03:00)

When this program was first filmed, Eleanor, age 51, was in the early stages of Alzheimer’s disease. This module follows Eleanor’s physical and mental decline after the initial filming. Pathology in the brainstem and other regions in the brains of Alzheimer’s patients are shown to interfere with acetylcholine release, resulting in neuronal atrophy. The module discusses our current knowledge of the disease and the direction of future research.

NASA's Radiation Belt Storm Probes (RBSP), the first twin-spacecraft mission designed to explore our planet's radiation belts, launched into the predawn skies. The two satellites, each weighing just less than 1,500 pounds, comprise the first dual-spacecraft mission specifically created to investigate this hazardous regions of near-Earth space, known as the radiation belts. These two belts, named for their discoverer, James Van Allen, encircle the planet and are filled with highly charged particles. The belts are affected by solar storms and coronal mass ejections and sometimes swell dramatically. When this occurs, they can pose dangers to communications, GPS satellites and human spaceflight.

Most spacecraft try to avoid the Van Allen Belts, two doughnut-shaped regions around Earth filled with "killer electrons." This morning NASA launched two heavily-shielded spacecraft directly into the belts. The Radiation Belt Storm Probes are on a two-year mission to study the Van Allen Belts and to unravel the mystery of their unpredictability. (04:28)

This interactive activity from NOVA examines how mutations in different regions of an organism's DNA affect gene expression—whether genes are turned on or off during the organism's development. An animated model depicts two DNA segments in the nucleus of a fertilized egg. Each segment contains a coding gene, enhancers in the noncoding regulatory region, and other DNA not associated with the gene. As the egg develops, each cell produces its own proteins. Whether and where these proteins bind to the DNA determines gene expression. Mutations can change how receptors in each of the regions permit or prevent such binding. This, in turn, influences which traits are displayed.

Dave Hackett is a master of illusion. The juniors in his science class at the Manufacturing Production Technology Academy (MPTA) of Laguna Creek High School, in Elk Grove, California, are too busy launching and chasing the rockets they made in class to notice they're actually learning physics. Hackett's class is part of a high school innovation movement known as career academies. They're small schools, located within larger comprehensive high schools, and they integrate academics with technical know-how in an occupation or industry that has important ties to the local region: renewable energy, health and science, agriculture, or, in the case of MPTA, computer-aided design and manufacturing.

UNESCO's Member States adopted a Declaration of Principles on Tolerance. Among other things, the Declaration affirms that tolerance is neither indulgence nor indifference. It is respect and appreciation of the rich variety of our world's cultures, our forms of expression and ways of being human. Tolerance recognizes the universal human rights and fundamental freedoms of others. People are naturally diverse; only tolerance can ensure the survival of mixed communities in every region of the globe. (02:55)

The Expedition team talks with Israeli, Palestinian and Jordanian students at the Arava Institute. A drought in the West Bank is exacerbating the situation in the already conflict-riddled region. As Israelis experience unprecedented water shortages, residential wells in drought-stricken Palestinian regions continue to dry up due to decreased rainfall and Israel’s tightening grip on water use. Parts of major West Bank cities such as Jenin, Hebron, and Bethlehem have experienced a lack of running water for weeks at a time. Even faucets in parts of Ramallah, the occupied West Bank’s political hub, which rarely experiences cuts, have been known to go dry for days at a time.The Expedition team talks with Israeli, Palestinian and Jordanian students at the Arava Institute where they are studying environmental and water issues as a vehicle for diplomacy, cooperation and ultimately, peace.

The Arctic Tern (Sterna paradisaea) makes an incredible migration each year. These small birds travel distances of more than 50,000 miles, from pole to pole, crossing through temperate and tropical regions along the way. Carsten Egevang used geo-locator tags to track ten of these terns, and he shares their story with us in this tour.

New Views of the Pillars of Creation, presented by Dr. Frank Summers, Space Telescope Science Institute. One of Hubble's most famous images was taken in 1995. The iconic "Pillars of Creation" shows the tall and beautiful gaseous pillar structures that can form inside star-forming regions. Within these dark clouds, stars are being born. Hubble kicked off its 25th anniversary year in 2015 with some images that used its improved cameras to revisit these beautiful pillars. This larger, higher resolution, and expanded wavelength examination uncovered new details, new features, and new perspectives on a classic image. (15:55)

Three years ago, we set out to make a film about the self-proclaimed Asparagus Capital of the Nation, the tiny rural community in western Michigan where Kirsten grew up in the 1970s and 80s. As the daughter of an asparagus farmer, Kirsten spent her childhood working on the farm and was a proud member of the pre-teen asparagus dance troupe The Oceana Stalkers. There was no question that asparagus was huge in Oceana County. Hailed as Green Gold, it was exactly what this poor rural community needed - a spring cash crop at the end of a long cold winter. Plus it was just about the only thing that would grow in their dry, sandy soil. Local merchants, housewives, and farmers banded together over the "Super Stalk." They baked the world's tallest asparagus cake, created "The Stalk" disco dance, and sang their asparagus songs all the way to the White House. Asparagus was King in Oceana County. Then came the U.S. War on Drugs. In 1991, when cocaine imports were at an all time high, The U.S. signed the Andean Trade Preference Act, eliminating all import tariffs on South American asparagus. The idea was that South American farmers would stop growing cocaine and start growing asparagus. Ten years later, the U.S. continues to send huge subsidies to Peru for their alternative crop program, but it was asparagus that exploded there, even though it grows in entirely different regions than cocaine! The Free Trade band wagon was moving fast, with NAFTA bringing an additional flood of Mexican asparagus. Now, China has started exporting their asparagus to the U.S! But where does all this leave the "'Asparagus Capital of the Nation"? In June of 2002, Kirsten invited Anne to visit the National Asparagus Festival and we found a community's identity at stake. Oceana County's pride and joy was in direct contrast with the speed with which their most valuable crop was being taken away. We realized that what was happening in Oceana County brought up really big questions about American identity and global economics, and about what gives a community a center. With the Foreign Policy decisions the U.S. Government is making today, how can a small community keep its pride, identity and source of economic survival? (6mins)

At a time when the health care debate is at the forefront of the political agenda, Uninsured in the Mississippi Delta puts a human face on the struggles of the 46 million Americans surviving without health care.
The Mississippi Delta is one of the most impoverished and uninsured regions of the United States. The area also has soaring rates for diabetes, hypertension and stroke, and some of the highest mortality rates and lowest birth rates in the nation. The town of Greenville, Mississippi, in the heart of the Delta, has, on a per-capita basis, the highest number of uninsured households in the country.
This film could be useful--most likely in a high school or higher education classroom--when discussing Mississippi culture and/or Mississippi history. Alternately, it would be a good video to introduce the concept of health care and the government's role in it. (05:42)
