Nancy Kedersha

Nancy Kedersha is a astronomy topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Nancy Kedersha rather than just read about it. In short: Nancy Kedersha (born 1951) is an American cell biologist and micrographer. She got her Ph.D. from Rutgers University where she worked in Richard Berg's lab studying the characteristics and assembly of prolyl hydroxylases.

Key takeaways

Nancy Kedersha belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Nancy Kedersha to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Nancy Kedersha from memory before moving on to harder problems.

Reference excerpt

Nancy Kedersha (born 1951) is an American cell biologist and micrographer. She got her Ph.D. from Rutgers University where she worked in Richard Berg's lab studying the characteristics and assembly of prolyl hydroxylases. Afterwards she joined Leonard Rome's lab at UCLA as a post-doctoral fellow where she co-discovered the vault (organelle). Subsequently, she worked at ImmunoGen Inc. where she worked on staining and photographing different cancer cells. She then worked as an instructor of medicine at Brigham and Women's Hospital in Paul Anderson's lab, where her work focused on studying stress granule formation. In late-2020, she retired. In addition to her contributions as a scientist, Kedersha has been quite successful in different microscopy competitions. She is a four-time Nikon Small World finalist and in 2011 she won the Lennart Nilsson Award.

Education and early life Kedersha is the daughter of Richard Kedersha, a professor of business administration and basketball coach at Rutgers University. She graduated high school from Rutherford High School in the class of 1969. After completing her bachelor's in biology from Bucknell University in 1973, Kedersha pursued her graduate studies at Rutgers University in Richard Berg's lab where she characterized the purification, assembly, and biosynthesis of prolyl hydroxylase. In 1983 she obtained her PhD in biochemistry.

Career From 1983 to 1988 Kedersha worked as a post doctoral fellow in Leonard Rome's lab at UCLA. In collaboration with Rome, she co-discovered the vault (organelle). The vault is this large cytoplasmic organelle found in eukaryotes, but whose function has not fully been elucidated. Recent studies done in trypanosome suggest it plays a role in trans-spliced mRNA. After her post-doctoral fellowship, Kedersha worked briefly in industry for ImmunoGen Inc. using microscopy to study cancer cells. She returned to academia where she became an instructor of medicine within Paul Anderson's lab at Brigham and Women's Hospital and studied stress granules. While there, she became the director of the confocal microscopy core. She also co-wrote a chapter in Translation Mechanisms and Control.

Awards and honors Kedersha has placed ten times in the Nikon Small World competition in which four of those times she was a finalist. She has also won the prestigious Lennart Nilsson Award in 2011 for her work in fluorescence microscopy.

Nancy Kedersha's colour images open our eyes to the smallest components of life. Through her work she has pushed cell biology into new scientific, pedagogical and aesthetic realms. With the aid of a confocal microscope, she has turned biological data into an artistic experience.

Worked examples

Example 1 — a first encounter with Nancy Kedersha

Start with the simplest possible case. Write down what Nancy Kedersha claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Nancy Kedersha before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Nancy Kedersha ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Nancy Kedersha

In research: Nancy Kedersha appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Nancy Kedersha in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Nancy Kedersha is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1951 births, American cell biologists, Bucknell University alumni, so understanding it makes those chapters shorter.
In everyday life: Look for Nancy Kedersha outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
