Model passage: Ants as gardeners

Many plants depend on animals to carry their seeds away from the parent, where seedlings would otherwise compete with it for light and water. Birds and mammals are the best-known dispersers, but in some ecosystems a humbler partner plays a surprisingly large role. Thousands of plant species produce seeds with a small, fatty attachment called an elaiosome. The structure plays no part in germination; its value lies entirely in its appeal to ants. Worker ants carry the seed back to the nest, where the elaiosome is fed to the larvae. The seed itself, hard and inedible, is then discarded, often among the colony's waste. For the plant, this is far from a disposal: the seed has been moved beyond the reach of many seed-eating animals and placed in soil unusually rich in nutrients. The arrangement is not, however, a perfect partnership. Some ants eat the seed as well as its reward, and others drop seeds only a short distance from the parent plant. Researchers therefore describe the relationship less as a contract than as a set of probabilities that, on balance, favour the plant.

Passage 1: The testing effect

4:00

For most students, a test is simply a means of measuring what has already been learned. A substantial body of research in cognitive psychology suggests that this view is incomplete. When learners are required to retrieve information from memory, rather than reread it, they tend to remember it considerably better at a later date, a phenomenon known as the testing effect. In a typical experiment, two groups study the same text. One group then rereads it, while the other attempts to recall its content without looking. On a test given a few minutes later, the rereading group often performs as well as the other group, or even better. After a delay of several days, however, the pattern is reversed, and the group that practised retrieval remembers markedly more. Rereading, it seems, produces a feeling of familiarity that learners mistake for mastery. Retrieval, by contrast, is effortful, and that very effort appears to strengthen the memory. The implication is somewhat counterintuitive: the strategies that feel most productive during study are not necessarily those that produce durable learning.

Passage 2: Governing the commons

4:00

In 1968 the ecologist Garrett Hardin published an influential essay arguing that resources shared by a community, such as pastures or fisheries, are doomed to overuse. Each user, he reasoned, gains the full benefit of taking a little more, while the cost of depletion is spread across everyone. Unless the resource was either privatised or regulated by the state, ruin was inevitable. Hardin's “tragedy of the commons” became a standard argument in economics and policy. The political scientist Elinor Ostrom challenged its pessimism not with a rival theory but with evidence. Studying cases ranging from alpine meadows in Switzerland to irrigation systems in Nepal, she documented communities that had managed shared resources sustainably, in some cases for centuries. These groups had not escaped the dilemma Hardin described; rather, they had devised their own rules for using the resource, monitored one another and imposed graduated penalties on those who broke the rules. Ostrom did not claim that self-governance always succeeds. Her point was that the choice between private ownership and state control was a false one. In 2009 she became the first woman to receive the Nobel Memorial Prize in Economic Sciences.

Passage 3: Reading the ice

4:00

Polar ice sheets are built up over thousands of years as layer upon layer of snow is compressed into ice. In the process, tiny pockets of air become sealed inside, and these bubbles preserve samples of the atmosphere as it was when they were trapped. By drilling long cylinders of ice, known as cores, and analysing the gas inside them, scientists can reconstruct past concentrations of carbon dioxide and other gases. The ice itself is equally informative. The proportions of different forms, or isotopes, of oxygen and hydrogen in the frozen water vary with the temperature at which the original snow formed, so they serve as an indirect thermometer. Cores drilled in Antarctica have extended this record back roughly 800,000 years, spanning several cycles of ice ages and warmer periods. Interpreting the record is not straightforward, however. Because snow takes many years to seal off from the atmosphere, the trapped air is younger than the ice that surrounds it, and researchers must correct for this difference before comparing the two records. Even so, ice cores remain one of the most direct archives of Earth's climate history.
