Flashcards
What is a pulsar?
What is a pulsar?
A celestial object that emits pulses of electromagnetic radiation at regular intervals.
Who discovered the first pulsar and who received the Nobel Prize?
Who discovered the first pulsar and who received the Nobel Prize?
Jocelyn Bell Burnell discovered the first pulsar in 1967. Antony Hewish and Bell Burnell published the findings in Nature, but only Hewish received the Nobel Prize in 1974.
What are T-cells and what did Tak Wah Mak discover about them?
What are T-cells and what did Tak Wah Mak discover about them?
T-cells are white blood cells that recognize antigens, which are molecules foreign to the body. Tak Wah Mak discovered that T-cell receptors have a unique genetic sequence.
