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.

11 Science-Backed Tips for Winning an Argument

For many people, arguing is something to avoid. But arguments can be used for good—they can inform, sharpen thinking, and challenge old ideas in important ways. The expert tips below will help you argue more incisively, which, in turn, will probably make you more likely to win the discussion. (Of course, winning means different things to different people—so not all of these concepts are about making someone else think you’re right.)

1. DETERMINE THE NATURE OF THE ARGUMENT.

According to Mark Porrovecchio, a professor of rhetoric and a debate coach at Oregon State University, understanding the nature of a disagreement will help you determine how best to handle it. “Argument styles vary according to context [and] genre,” he tells Mental Floss. “What might work when arguing with a significant other could backfire when debating with a colleague. The goal is to be mindful of the type of situation you are in … and to be willing to adjust your approach based on a host of situational factors.”

You should adjust your tone—and even the content of your argument—depending on the person with whom you are having it and the place it’s happening. The conversation in a private setting may be a different from one in a public space. This particular tactic, Porrovecchio says, is as old as debate itself: Both the Sophists and Aristotle used it.

2. KNOW YOUR OPPONENT'S PERSONALITY TYPE …

Sometimes you won’t know what your opponent values or what their background is—but sometimes, you will. Use that information.

Most people are either reactive or analytical, says Prince Ghuman, a professor at Hult International Business School and coauthor of the book Allure: the Neuroscience of Consumerism. “Some people tend to be more reactive, so you can convince them using techniques that appeal to them—emotion and empathy," he tells Mental Floss. "Others seem to be more deliberate—you’ll need to provide an analytical support for your argument."

3. … AND MORAL IDENTITY.

In political and ideological arguments, different sides often have fundamentally different ways of looking at the world. According to the moral foundations theory, a framework proposed by a group of social psychologists, most people see society through six different binaries: care/harm, fairness/cheating, loyalty/betrayal, authority/subversion, sanctity/degradation, and liberty/oppression. A politically liberal person, for example, might be more affected by an argument that stresses compassion and fairness, whereas conservatives might find loyalty and authority to be more important. Each person will have a unique idea of which concept in each pair carries more weight, and in an argument, knowing what the other side values can help frame your talking points.

“One reason it’s so hard to reach across the ideological divide is that people tend to present their arguments in a way that appeals to the ethics of their own side, rather than that of their opponents,” journalist Olga Khazan explained in an Atlantic video. Framing your argument to appeal to your opponents' moral code rather than your own can help you win.

4. USE EMOTION—BUT DON'T REST YOUR ENTIRE ARGUMENT ON IT.

Not only is arguing sans emotion almost impossible if you're a human being, it’s also not a great way to succeed. “Every argument, even many seemingly factual arguments, contains an emotional element,” Porrovecchio says.

According to psychologist Sherrie Campbell, author of Success Equations: A Path to Living an Emotionally Wealthy Life, you should include feelings when you make your case, but don’t go too far with an emotional point—especially in professional settings. When it comes to personal disagreements, uncomfortable feelings can sometimes be necessary, and while kindness is important, so is honesty.

“Sometimes emotional arguments that bring about sadness can help people get to the core of where the hurt and frustration is," Campbell says. "As long as the person you're arguing with has empathy and can put caring over being right, then emotional arguments can be effective.”

Ideally, you should try to keep it balanced. “An argument that relies solely on emotion should be treated with suspicion,” Porrovecchio says. Feelings without information or details to back them up fall flat if the other person can’t relate.

5. MAKE YOUR CASE WITH EMPATHY.

“Connect to the listener by conveying your story through one person’s example. Personify, rather than generalize,” Ghuman suggests. He cites research [PDF] by psychologists at the University of Oregon that shows people will donate more money to an individual in need than a group of people. That’s because most of us can empathize with one person but find it harder to relate to groups in the same way. When arguing, use this tactic to your advantage by finding (or imagining) a specific person who might be helped by what you are arguing for.

For instance, if you are arguing that Peggy shouldn’t be fined for parking her car in a tow zone because she was trying to rescue a dog in the street, it would make more sense to describe who she is specifically. Rather than call her “Peggy, a dog owner,” describing her as “Peggy, who has adopted a mutt, a pitbull, and an elderly chihuahua,” would render her more sympathetic. Empathetic details shouldn't be used as replacements for factual information, though; they should be additions to the facts.

6. USE STORYTELLING.

Storytelling works hand-in-hand with empathy and puts data to support your argument in context. Pull all your information together—using empathy, facts, and emotions—to create a compelling story, and your argument will be tougher to beat. When your point seems part of a narrative arc, each aspect of what you're arguing is harder to pick on.

Need a template? Porovecchio recommends the TED format. “I think TED Talks have gained popular cachet because they often manage to balance a degree of detail and fact with a personable, narrative-driven delivery style,” he says.

7. INFLUENCE YOUR ADVERSARY WITH PHYSICAL CUES.

People unconsciously mimic others in social situations, a behavior that psychologists believe is associated with emotional connection. Consciously imitating the posture and movement of your opponent is also a well-known way to bring someone over to your side. Try leaning back if your opponent does so, or cross your arms or legs the way they do. Looking them in the eye when you are listening to them speak is another to reduce their confidence in their own argument—and you’ll look stronger, too. You can even lower your voice a notch to sound more dominant, according to this study.

8. REMAIN CALM.

Whether you are using or responding to an analytic or emotional argument, keep it as relaxed as possible. “The best thing to do when in an argument is to stay calm and talk slowly—you can't yell and talk slowly at the same time,” Campbell says. “Forcing yourself to talk slowly helps to keep the emotions under control and your thoughts rational.” If that sounds like a challenge, it is: “This takes a lot of discipline, but it's a simple thing to focus on.”

9. PRACTICE YOUR DELIVERY.

Like most other skills, spending time arguing will make you better at it. Debate in high school, college, or in a professional-development context “should be viewed as a way to practice the skills of arguing,” Porrovecchio says. “You work to improve your technique, your content, your delivery; then use what you have learned in real world situations.” Porrovecchio says he’s seen his students become not just better debaters over time, but also “better public speakers and critical thinkers.”

10. REFRAME THE DEBATE.

Not all arguments have to be about being right, which some people define as winning. You might consider it a win if your opinion is valued and considered by the person you are disagreeing with—even if you don't change their mind. “Instead of the word argument, replace it with conversation. If you're just having a conversation, then winning is off the table, and a productive discussion can occur,” Campbell says.

11. IF ALL ELSE FAILS, WALK AWAY.

Sometimes it gets ugly, or the argument seems to be going in circles. If you’re not getting anywhere in a discussion, “ask your opponent directly: ‘Is there anything I can do to change your mind?’ If they say that nothing will change their mind, believe them, and walk away,” Ghuman says. Sometimes an argument is a draw—and that’s OK. You’ve won if you’ve learned something, Ghuman adds: “Healthy argument can expand your perspective and open your mind.”

10 Riveting Facts About Mars

Mars's dust storms can be global. In these images taken a month apart in 2001, the dust storm near the southern polar ice cap (left) soon enveloped the entire planet (right).

Few celestial objects have fascinated humankind throughout history more than the Red Planet. For over a century, we've longed to know more about Mars and the beings that we speculated lived there. When NASA dispelled the notion of creatures scurrying along the rusty plains, it raised a more tantalizing prospect: that we might one day be the creatures that call Mars home.

Mental Floss spoke to Kirby Runyon, a researcher at the Johns Hopkins University Applied Physics Laboratory, and Tanya Harrison, the director of research for Arizona State University's NewSpace Initiative, to learn more about the place your kids might live one day.

1. A MARTIAN YEAR LASTS JUST UNDER TWO EARTH YEARS.

It takes 687 Earth days for the Red Planet make its way around the Sun. A Mars day—called a sol—lasts 24.6 hours, which would be a nuisance for the circadian rhythms of astronauts (but not as bad as a day on Venus, which lasts 5832 hours).

2. IT'S NOT AS HOT AS IT MIGHT LOOK.

Mars looks desert-hot—New Mexico with hazy skies, red because of its iron oxide soil—but is actually very cold, with a blistering hot sol being 70°F, and a cold sol a brisk -225°F. Its dust storms can be huge; in 2018, one storm grew so large that it encompassed the entire planet for more than a month. (You can see a similarly huge dust storm in the image above.)

3. MARS IS MUCH SMALLER THAN EARTH ...

Compared to Earth, Mars is a tiny Styrofoam ball, with a diameter just over half of ours and one-tenth of our mass. Its gravity will be an absolute nightmare for future colonists, at .38 that of their native planet. (That means a person weighing 100 pounds here would weigh just 38 pounds on Mars.)

4. ... AND ITS ATMOSPHERE IS MOSTLY CARBON DIOXIDE.

You won't want to get a breath of fresh air on Mars unless you're trying to suffocate: Its atmosphere is 95.32 percent carbon dioxide, with a little nitrogen and argon thrown in. (Earth's atmosphere, by contrast, is mostly nitrogen and oxygen.) When you do try to take that single, hopeless breath, the tears on your eyeballs, saliva in your mouth, and water in your lungs will immediately evaporate. You won't die right away, but you'll probably want to.

5. IT HAS TWO MOONS, BOTH WITH BETTER NAMES THAN OURS.

They're called Phobos and Deimos, which translate to Fear and Dread, respectively. They're shaped like potatoes and don't exactly fill the evening sky: Standing on the Martian surface, Phobos would appear to be about one-third the size of Earth's moon; Deimos would look like a bright star.

Future human Martians will have to enjoy Phobos while they can. The tidal forces of Mars are tearing Phobos apart; in 50 million years, the big potato will disintegrate.

In the meantime, Phobos is one of the stepping stones NASA plans to take on its journey to Mars. No part of human exploration of the Red Planet is easy, and before we land on Mars (and then have to figure out how to launch back into space and somehow get back to Earth), it's vastly easier to land on Phobos, do a little reconnaissance, and then take off and return home. As a bonus, on the journey to Phobos [PDF], astronauts can bring along hardware necessary for eventual Martian settlement, making the ride a lot easier for the next astronauts.

6. MARS IS HOME TO THE TALLEST MOUNTAIN IN THE SOLAR SYSTEM.

The tallest mountain on Earth, Mount Everest, is 29,029 feet tall. Olympus Mons on Mars is over 72,000 feet in height, making it the tallest mountain by far on any planet in the solar system.

Olympus Mons isn't the only extraordinary Mars feature: Mountaineers might also want to check out NASA's trail map for hiking the famous Face on Mars. If canyons are more your speed, you'll want to visit Valles Marineris. It is the size of North America and, at its bottom, four miles deep. (In the solar system, only Earth's Atlantic Ocean is deeper.) Once Earth's ice caps finish melting, you can always visit the ones on Mars. (If you have a telescope, you can easily see them; they are the planet's most distinctive features visible from your backyard.)

7. THE IDEA OF MARTIANS GOES BACK OVER A CENTURY.

That's partially because of popular fiction (War of the Worlds, the 1897 novel by H.G. Wells, sees a Martian invasion force invade England) and partially because of Percival Lowell, the famed astronomer who wrote prolifically on the canals he thought he was observing through his telescope, and why they might be necessary for the survival of the Martian people. (Mars was drying up.)

Though it's easy to dismiss such conclusions today, at the time Lowell not only popularized space science like few others, but left behind the Lowell Observatory in Flagstaff, Arizona—one of the oldest observatories in America and the place where Clyde Tombaugh discovered Pluto.

8. IF THERE ARE MARTIANS, THEY ARE MICROBES.

Today, scientists work tirelessly to unlock the complex geologic history of Mars, to determine whether life exists there today, or did long ago. "We think that Mars was most globally conducive to life around 3.5 to 3.8 billion years ago," Runyon tells Mental Floss. "In the Mars geologic history, that's the end of the Noachian and toward the beginning of the Hesperian epochs." There may once have been a hemispheric ocean on Mars. Later, the world might have alternated between being wet and dry, with an ocean giving way to massive crater lakes. Where there's water, there's a good chance of life.

"If we found life on Mars—either extinct or current—that's really interesting," says Runyon, "but more interesting than that, is whether this life arose independently on Mars, separate from Earth." It is conceivable that meteorite impacts on Earth blasted life-bearing rocks into space and eventually to the Martian surface: "A second life emergence on Mars is not just a geological question. It's a biogeochemical question. We know that Mars is habitable, but we haven't answered the question of whether it had, or has, life."

9. NASA SPENDS A LOT OF TIME OUT THERE.

Mars hasn't hurt for missions in recent years, though scientists now warn of an exploration desert beyond 2020. But that doesn't mean we humans don't have eyes on the planet. Presently in orbit around the planet are the Mars Reconnaissance Orbiter, which images and scans the planet; MAVEN, which studies its atmosphere; Mars Express, the European Space Agency's first Mars mission; MOM, the first Mars mission by the Indian Space Research Organization; the ESA's ExoMars Trace Gas Orbiter, which is searching for methane in the Martian atmosphere; and Odyssey, which studies Mars for water and ice signatures, and acts as a communications relay for vehicles on the ground.

Rolling around on the Martian surface are Curiosity and Opportunity—NASA missions both—which study Martian geology. Though the Russians and Europeans have tried mightily to do so, NASA is the only space agency to successfully land spacecraft on the Martian surface (seven times).

In November 2018, the InSight mission will land on Mars, where it will study the planet's interior. In 2020, NASA will land the Mars 2020 rover; where Curiosity studies Mars for signs of habitability, Mars 2020 will look for inhabitants.

"It is going to collect samples that will hopefully be brought back to Earth," says Runyon. "The three landing sites selected for Mars 2020 are Northeast Syrtis, Jezero Crater, and Columbia Hills within Gusev Crater, which is where the dead rover Spirit is currently sitting. Each of these sites is a hydrothermal environment dating from the Noachian-Hesperian boundary. These are some of the most perfect places to look for past signs of Martian life, and can help answer the question of whether life had a second genesis on Mars."

10. MARS IS CHANGING, BUT NOBODY KNOWS WHY.

"Most people don't realize how active Mars is," Harrison tells Mental Floss. "Other planets aren't just these dead worlds that are frozen in time outside of our own. There are actually things happening there right now." Imagery from the HiRISE and Context Camera instruments on the Mars Reconnaissance Orbiter have revealed such events as avalanches, sand dune erosion [PDF], and recurring slope lineae (flowing Martian saltwater).

Things are moving, but it's not always clear why. "There's a lot of material that has been eroded away," says Harrison. "We have entire provinces of the planet that look like they've been completely buried and then exhumed. And that's a lot of material. The big question is, where did it all go? And what process eroded it all away?" Curiosity might help answer the question, but to really understand the processes and history of the fourth rock from the Sun, we're going to need to send geologists in spacesuits. "You can't replace human intuition with a rover," Harrison says. "Looking at a picture on your computer is not the same as standing there and looking around at the context, stratigraphic columns, being able to pick up the rocks and manipulate them, take a hammer to things. So once humans land on the surface, it'll be kind of like the difference between what we knew about Mars from Viking and Mars Global Surveyor and then the revolution between Mars Global Surveyor and Mars Reconnaissance Orbiter. Our view of what we think happened on Mars is going to completely change, and we'll find out that a lot of what we thought we knew was wrong."
