Today would have been the 98th birthday of English chemist Rosalind Franklin, a brilliant and dedicated scientist best known for the honor denied her: the 1962 Nobel Prize for discovering the structure of DNA. Here are 15 facts about her.

1. SHE KNEW HER CALLING EARLY, BUT HER FATHER RESISTED EDUCATING A DAUGHTER.

Rosalind Elsie Franklin was born in London in 1920. She was one of five children born into a wealthy Jewish family. She decided she wanted to become a scientist at 15, and passed the admissions exam for Cambridge University. However, her father, Ellis, a merchant banker, objected to women going to college and refused to pay her tuition. Her aunt and mother finally managed to change his mind, and she enrolled at Cambridge's all-female Newnham College in 1938.

2. SHE ATTENDED COLLEGE WITH ANOTHER WOMAN WHO DIDN'T GET FULL CREDIT FOR HER WORK.

Bletchley Park cryptanalyst Joan Clarke was a few years older than Franklin, but they were both at Newnham in the late 1930s. Clarke would go on to be recruited for the war effort, cracking the German Enigma codes. The full scope of Clarke's work is still unknown, due to government secrecy.

3. HER SCHOLASTIC ACHIEVEMENTS WERE DENIED BY HER UNIVERSITY FOR YEARS.

Despite Newnham College having been at Cambridge since 1871, the university refused to accept women as full members until 1948, seven years after Franklin earned the title of a degree in chemistry. Oxford University started granting women's degrees in 1920.

4. HER RESEARCH ON COAL HELPED THE AEROSPACE INDUSTRY.

After graduation, Franklin got a job at the British Coal Utilization Research Association (BCURA), where she researched coal and charcoal, and how it could be used for more than fuel. Her research formed the basis for her 1945 doctoral dissertation; it and several of her later papers on the micro-structures of carbon fibers played a role in the eventual use of carbon composites in air- and spacecraft construction.

5. HER MALE COLLEAGUES WERE HOSTILE AND UNDERMINED HER RESEARCH.

Franklin had a direct nature and was unwilling to be traditionally feminine. One reason she left Cambridge to work on coal was that her doctoral supervisor did not like her and believed women would always be less than men. When she was hired in 1951 at King's College, London, to work on DNA, she clashed with researcher Maurice Wilkins, who had thought she was his assistant, not his equal. Meanwhile, Franklin was under the impression that she'd be completely independent. Their relationship got worse and worse the longer they worked together. Wilkins went so far as to share Franklin's research without telling her with James Watson and Francis Crick—even though they were technically his competitors, funded by Cambridge University. Watson was particularly nasty about Franklin in his 1968 book, The Double Helix, criticizing her appearance and saying she had to be “put in her place.”

6. HOW EVENTS UNFOLDED IN THE DISCOVERY OF DNA'S STRUCTURE IS STILL DEBATED TODAY.

Many books have been written hashing over events, either criticizing Watson and Crick, saying they stole Franklin's research, or defending the duo, saying her research helped them but that Franklin would not ultimately have reached their conclusions on her own. Though Franklin and Watson never became friendly, Crick and his wife welcomed Franklin into their home while she was being treated for ovarian cancer.

7. HER WORK MAY HAVE LED TO HER UNTIMELY DEATH.

Franklin died of cancer in 1958. She was 37. Though genetics likely played a part in her illness, her work with crystal x-ray diffraction, which involved constant exposure to radiation, did not help. She is not the first woman in science to risk her health for her research. Marie Curie died from aplastic anemia, which has been tied to radiation exposure. Many of Curie's personal belongings, including her cookbooks, are too radioactive to handle even today.

8. HAD SHE LIVED LONGER, SHE MAY HAVE QUALIFIED FOR MORE THAN ONE NOBEL PRIZE.

The first, of course, would have been awarded with Watson, Crick, and Wilkins, had they been made to share credit with her. (Pierre Curie had to ask the Nobel Committee to add his wife to the nomination in 1903.) As for the second, chemist Aaron Klug won the prize in 1982, carrying on work he and Franklin had started on viruses in 1953, after she left King's College. Because of the rules at the time of her death about awarding prizes posthumously (and in 1974 all posthumous awards were eliminated, the sole exception being in 2011), Franklin has none.

9. DESPITE BEING DENIED HER PRIZE, SHE'S BEEN HONORED BY MANY ACADEMICS.

In 2004, the Chicago Medical School renamed itself the Rosalind Franklin University of Medicine and Science. She has also had a number of academic programs, auditoriums, and labs named for her. In 2013, Newnham College principal Dame Carol Black helped install a plaque commemorating Franklin at the Eagle Pub in Cambridge. Crick and Watson, who already had a plaque in the pub, drank there often while working on the DNA project, and allegedly boasted about discovering “the secret of life” to other patrons.

10. SHE IS THE SUBJECT OF SEVERAL BIOGRAPHIES.

The first, 1975's Rosalind Franklin and DNA, was written by her friend Anne Sayre, largely as a reaction to Watson's The Double Helix. In 2002, Brenda Maddox published Rosalind Franklin: The Dark Lady of DNA.

11. AN OBJECT IN SPACE IS NAMED AFTER HER.

In 1997, amateur Australian astronomer John Broughton discovered an asteroid, which he named 9241 Rosfranklin.

12. AT LEAST ONE HISTORY RAP BATTLE IS ABOUT HER.

It was produced by seventh graders in Oakland, California (with some help from teacher Tom McFadden). And it is delightful.

13. SHE HAS BEEN IMMORTALIZED ON THE SMALL SCREEN AND THE BIG STAGE.

In 1987, BBC's Horizon series aired The Race for the Double Helix, starring Juliet Stevenson as Franklin. Jeff Goldblum played Watson. In 2011, playwright Anna Ziegler premiered a one-act about Franklin called Photograph 51. It opened on the West End in 2015, starring Nicole Kidman as Franklin.

14. THE 2015 RUN OF PHOTOGRAPH 51 RE-IGNITED THE OLD CONTROVERSY.

While Kidman got much praise from critics for her turn as Franklin in Photograph 51, Maurice Wilkins' friends and former colleagues have taken exception to a scene where Wilkins takes a photograph—the titular Photo 51, which showed evidence of DNA's structure—from Franklin's desk when she isn't there, saying he would never have done something so dishonorable.

15. THE PLAY MAY COME TO THE BIG SCREEN IN THE NEXT FEW YEARS.

In 2016, the West End production's director, Michael Grandage, told The Hollywood Reporter that he hopes to turn the play into a film—with Kidman reprising the role.

How Did 6 Feet Become the Standard Grave Depth?

It all started with the plague: The origins of “six feet under” come from a 1665 outbreak in England. As the disease swept the country, the mayor of London literally laid down the law about how to deal with the bodies to avoid further infections. Among his specifications—made in “Orders Conceived and Published by the Lord Mayor and Aldermen of the City of London, Concerning the Infection of the Plague”—was that “all the graves shall be at least six feet deep.”

The law eventually fell out of favor both in England and its colonies. Modern American burial laws vary from state to state, though many states simply require a minimum of 18 inches of soil on top of the casket or burial vault (or two feet of soil if the body is not enclosed in anything). Given an 18-inch dirt buffer and the height of the average casket (which appears to be approximately 30 inches), a grave as shallow as four feet would be fine.

A typical modern burial involves a body pumped full of chemical preservatives sealed inside a sturdy metal casket, which is itself sealed inside a steel or cement burial vault. It’s less of a hospitable environment for microbes than the grave used to be. For untypical burials, though—where the body isn’t embalmed, a vault isn’t used, or the casket is wood instead of metal or is foregone entirely—even these less strict burial standards provide a measure of safety and comfort. Without any protection, and subjected to a few years of soil erosion, the bones of the dearly departed could inconveniently and unexpectedly surface or get too close to the living, scaring people and acting as disease vectors. The minimum depth helps keep the dead down where they belong.

One Good Reason Not to Hold in a Fart: It Could Leak Out of Your Mouth

The next time you hold in a fart for fear of being heard by polite company, just remember this: It could leak out of your mouth instead of your butt. Writing on The Conversation, University of Newcastle nutrition and dietetics professor Clare Collins explains that pent-up gas can pass through your gut wall and get reabsorbed into your circulation. It's then released when you exhale, whether you like it or not.

“Holding on too long means the build up of intestinal gas will eventually escape via an uncontrollable fart,” Collins writes. In this case, the fart comes out of the wrong end. Talk about potty mouth.

A few brave scientists have investigated the phenomenon of flatulence. In one study, 10 healthy volunteers were fed half a can of baked beans in addition to their regular diets and given a rectal catheter to measure their farts over a 24-hour period. Although it was a small sample, the results were still telling. Men and women let loose the same amount of gas, and the average number of “flatus episodes” (a single fart, or series of farts) during that period was eight. Another study of 10 people found that high-fiber diets led to fewer but bigger farts, and a third study found that gases containing sulphur are the culprit of the world’s stinkiest farts. Two judges were tapped to rate the odor intensity of each toot, and we can only hope that they made it out alive.

Scientific literature also seems to support Collins’s advice to “let it go.” A 2010 paper on “Methane and the gastrointestinal tract” says methane, hydrogen sulfide, and other gases that are produced in the intestinal tract are mostly eliminated from the body via the anus or “expelled from the lungs.” Holding it in can lead to belching, flatulence, bloating, and pain. And in some severe cases, pouches can form along the wall of the colon and get infected, causing diverticulitis.

So go ahead and let it rip, just like nature intended—but maybe try to find an empty room first.
