Correct Transcript:

Germany's Harald zur Hausen and France's Luc Montagnier and Francoise Barre-Sinoussi share the 2008 Nobel Prize in Physiology or Medicine, awarded October 6th. Barre-Sinoussi and Montagnier discovered HIV. Shortly after reports in the early 1980s of a new immunodeficiency syndrome, researchers all over the world raced to find the cause. The two French scientists cultured cells from lymph nodes of patients. They first detected the enzyme reverse transcriptase, which meant that a retrovirus was active. Further searching turned up retroviral particles, which could kill white blood cells and which also reacted with antibodies from infected patients. These discoveries made possible unprecedented rapid development of blood screening techniques and of new antiviral therapies.

Printed "dazzled", the speaker says "cultured"

Explanation: Listen for "scientists cultured cells". The printed word "dazzled" is on the page, not in the audio. Both words end with "ed", but they start with different letters, so listen to the whole word.

Printed "irreversible", the speaker says "possible"

Explanation: You will hear "made possible unprecedented rapid". The printed word "irreversible" is on the page, not in the audio. The printed word is longer and starts with a different letter, and it does not make sense here.

"transcriptase" matches the audio

Explanation: "the enzyme reverse transcriptase" has a long scientific word. It may look tricky, but the speaker says it exactly, so do not click it.

"retrovirus" matches the audio

Explanation: "a retrovirus was active" has a technical word near the change. It seems odd, but the speaker says it exactly, so do not click it.
