A small new study found that people fluent in sign language had significantly better peripheral vision and reaction time than people who couldn’t sign. The research was published in the journal Frontiers in Psychology.

Researchers in the UK recruited 17 people who had been deaf since birth, eight hearing people fluent in British Sign Language (BSL), and 18 hearing people who didn’t sign at all. They brought everyone in to the laboratory and sat them down in front of computers to test their visual acuity, range, and reaction time.

Participants who had been signing from a young age fared far better than the other participants on visual tasks. “Deaf people have exceptional visual abilities that hearing adults do not,” lead author Charlotte Codina of the University of Sheffield said in a statement. “We found that deaf adults have faster reaction times around the whole of the visual field, extending as far as 85 degrees peripherally near the edge of vision.”

These results were unsurprising to Codina and her colleagues. The idea of sensory compensation—experiencing improvement in one sense when another is limited—is, by now, quite well established.

Less expected was that while deaf participants’ scores were the most impressive, they were followed by another group: hearing people who worked as BSL interpreters. These results suggest that fluency in sign language requires or builds visual processing skills that non-signers don’t have, and that adulthood is not too late to learn and benefit from the language.

BSL is not the only form of sign language used in the UK, but it is the most common. It includes a finger-spelled English alphabet, but is otherwise quite different from spoken English.

This was a small study, conducted on small groups of adults in a small country, but the researchers believe their results can be validated in future studies.

Getting a good night's sleep is key to your health, but what's the best position for maximizing those benefits? According to SciShow, the answer depends on who you are and what your body is presently doing. Do you have acid reflux? You might want to avoid sleeping on your right side, since studies have shown that can aggravate heartburn (though scientists still aren't quite sure why). Are you pregnant? Aim for the left side, since it helps blood and nutrients flow to the placenta, among other benefits. Do you snore? Maybe avoid sleeping on your back, and roll over on your side instead. The video below goes over the whole menu of possible sleeping positions, and explains which ones will help you get the most out of your 40 winks.

14 Facts About Margaret Sanger

Born in 1879, activist Margaret Sanger sparked both revolution and controversy when she began pushing for legalized access to birth control and founded the Planned Parenthood Federation of America. Sanger remains a controversial figure even today, more than 50 years after her death.

1. SHE BLAMED HER FATHER FOR HER MOTHER'S DEATH.

Sanger was born Margaret Louise Higgins, the sixth of 11 children. Her mother, Anne Purcell Higgins, also had seven miscarriages, for a grand total of 18 pregnancies within 22 years. She suffered from poor health for much of that time, and when Anne died of tuberculosis at age 50, Margaret was just 19 years old. According to TIME Magazine, Margaret confronted her father at her mother's coffin and said, "You caused this. Mother is dead from having too many children."

2. SHE WANTED TO BE A DOCTOR.

Sadly, medical school was too expensive, so instead she entered a probationary nursing program in 1900. In early 1902, she met architect William Sanger. The two got married later that year and moved to Hastings-on-Hudson, New York, a suburb about 20 miles away from New York City. They had three children.

3. HER HOUSE CAUGHT FIRE, LEADING HER TO MOVE TO THE CITY.

After the Sangers' house in Hastings-on-Hudson caught fire, Sanger stopped enjoying life in the suburbs. By 1911 the couple had decided to start a new life in Greenwich Village, where Sanger joined the Women's Committee of the New York Socialist Party. There, she met fellow radicals and reformers—like novelist Upton Sinclair, anarchist Emma Goldman, art patron Mabel Dodge Luhan, and intellectual Max Eastman—who supported her ambitions to help working women.

In New York City, Sanger decided to jump back into her career by working as a visiting nurse in the Lower East Side tenements. She often treated women who attempted to give themselves abortions because they didn't have the money to care for another child. Dismayed by the poor health and poverty she saw among immigrants there, she developed opinions that would later lead to her advocacy for birth control.

4. SHE BELIEVED BIRTH CONTROL WAS A FREE SPEECH ISSUE.

Soon after arriving in Greenwich Village, Sanger began writing sex education columns for the New York Call, a socialist newspaper. Her frank discussion of women's sexuality and reproduction offended some readers. In 1913, politician and post office official Anthony Comstock censored her column because he considered her usage of words like syphilis and gonorrhea too vulgar.

A year after her column in the New York Call was banned, Sanger launched The Woman Rebel, an eight-page monthly newsletter advocating contraceptive use. Operating under the slogan "No gods, no masters," Sanger used the newsletter to openly defy Comstock's eponymous 1873 laws. (The Comstock laws made it illegal to use the United States Postal Service to send anything containing information about contraceptives or anything else deemed obscene.) She was indicted in August 1914, but she fled to Europe to avoid arrest. She would eventually return to the United States to face trial, but in February 1916 the prosecution dropped the charges.

5. SHE WAS AGAINST ABORTION.

Despite her advocacy for family limitation, Sanger disliked the idea of abortion. She believed proper education and legalized contraceptives would reduce the need for the procedure. In her 1938 autobiography, Sanger described her experience treating Sadie Sachs, one of the women in the East Side tenements. In 1912, Sachs's husband called for Sanger's help after he found Sachs unconscious from a self-induced abortion. After three weeks of treatment from both Sanger and a local doctor, the only advice the doctor could offer Sachs was to avoid "any more such capers" and have her husband sleep on the roof.

Three months later, Sachs became comatose from another self-induced abortion, and Sachs's husband again reached out to Sanger for help. The woman died within 10 minutes of Sanger's arrival. Frustrated by the lack of resources and information available to lower-class women, Sanger resolved to make changes. From that time forward, she wrote, she wanted to "do something to change the destiny of mothers whose miseries were as vast as the skies."

6. SHE POPULARIZED THE TERM BIRTH CONTROL.

Sanger is often credited for coining the term, but that honor actually goes to Robert Parker, a friend of hers who helped create The Woman Rebel. In her 1979 biography on Sanger, author Madeline Gray described Parker as a polio victim who studied yoga with the hopes of gaining more control over his partly paralyzed hand. Gray wrote:

"It occurred to him that control might apply to birth as well. 'Birth control,' he mused. 'Birth control … I think I like it.' They all liked it. As they put on their hats and left, they agreed that birth control was the best name for the movement."

Otto Bobsien, another of Sanger's colleagues, was the first to use the term to proclaim the start of the Birth Control League of America, a new organization he later said "never had more than a nominal existence." In 1915, when Sanger was away in Europe, Bobsien joined the National Birth Control League and offered the fledgling organization use of the movement's new name. When Sanger returned from Europe later that year, she helped popularize the term, considering it more straightforward than phrases like "family limitation."

7. SHE OPENED THE FIRST BIRTH CONTROL CLINIC IN THE U.S.

In October 1916, Margaret Sanger opened a birth control clinic in Brooklyn with the help of her sister, Ethel Byrne, and interpreter Fania Mindell. It was the first of its kind in the U.S., and she modeled it after a Dutch clinic she had visited while evading American police. In the Netherlands, Sanger had learned about pessaries and diaphragms and became convinced they were more effective than the suppositories and douches she promoted in the United States. Sanger brought that new knowledge to her Brooklyn clinic, which served more than 100 women on its first day. For a cover charge of 10 cents, Sanger gave every woman a pamphlet of her New York Call column on "What Every Girl Should Know," a lecture on the female reproductive system, and instructions on several types of contraceptive use. The clinic closed just nine days later when Sanger was once again arrested for violating the Comstock laws. Sanger immediately attempted to reopen the clinic after being released on bail, but, as she wrote, she was promptly re-arrested and charged as a public nuisance.

8. SHE ONCE TOLD A JUDGE SHE COULDN'T RESPECT EXISTING LAWS.

Sanger and Byrne's court trials began in January 1917. Sanger's sister was tried first and sentenced to 30 days in a workhouse, but she immediately went on a hunger strike; Byrne fasted for a week before being force-fed by prison staff. When Sanger went to trial on January 29, she was supported in court by several Greenwich Village socialites and about 50 of the women she'd treated in the Brooklyn clinic. Presiding Justice John J. Freschi offered her a lenient sentence if she promised to obey the law, but Sanger responded by saying, "I cannot respect the law as it exists today." Sanger was found guilty and Freschi also sentenced her to 30 days in a prison workhouse.

In 1918, Sanger appealed the court decision and won a victory for the birth control movement. Although the court upheld Sanger's conviction and she still had to serve her 30 day sentence, Judge Frederick E. Crane of the New York Court of Appeals also ruled that doctors could prescribe contraceptives and disseminate information about birth control under certain conditions. Sanger ran with the new loophole in 1923, when she established a new clinic staffed largely by female doctors. The new clinic operated alongside the American Birth Control League. Almost two decades later, in 1939, the league and the clinic merged, forming the Birth Control Federation of America, and in 1942 this new organization officially became known as the Planned Parenthood Federation of America.

9. THE ROCKEFELLERS ANONYMOUSLY SUPPORTED HER CAUSE.

In the mid-1920s, John D. Rockefeller Jr. anonymously donated $10,000 to the American Birth Control League to fund research into contraceptives. Rockefeller's son, John D. Rockefeller III, continued his father's early support of Sanger's work, albeit more publicly. The Rockefeller Brothers Fund donated money to Planned Parenthood until 1981, when it decided to start funding agricultural research—which was decidedly less controversial—instead.

10. LIKE MANY WELL-KNOWN INTELLECTUALS OF HER DAY, SANGER SUPPORTED EUGENICS.

Many historians believe Sanger's support of eugenics was part strategic and part ideological. Sir Francis Galton, a cousin of Charles Darwin's, initiated the Western eugenics movement by suggesting that traits like "talent and character" could be passed down to children through intentional breeding. Several British and American academics latched onto the idea, including figures like Theodore Roosevelt, John D. Rockefeller Jr., and Alexander Graham Bell. Sanger's support for sterilizing the diseased and "feebleminded" legitimized the birth control movement by aligning her ideas with those of contemporary intellectuals.

Sanger's belief in eugenics was a little different from other intellectuals', though. Eugenicists, she said, believed a woman's first duty should be to the state, and that all "fit" women should bear children. Sanger, on the other hand, thought a woman's first duty should be to herself. She contended the primary reason for birth control was to prevent pregnancies among women who couldn't support a child financially. Sanger believed her ideal of economic eugenics was morally superior to the views posed by traditional eugenicists.

The modern-day Planned Parenthood doesn’t hide Sanger's controversial support of the eugenics movement, but it doesn't endorse it, either. In a document published in 2016 [PDF], the organization said, "We believe that [those ideas] are wrong. Furthermore, we hope that this acknowledgement fosters an open conversation on racism and ableism—both inside and out of our organization."

11. HER BOOKS WERE AMONG THE FIRST BURNED BY NAZIS.

In May 1933, Nazis sanctioned the burning of more than 25,000 books deemed "un-German." Sanger had published at least nine books by that point, and they were all among that number, as were titles by Jack London, Ernest Hemingway, Sigmund Freud, Albert Einstein, and dozens of others. Sanger's books, which advocated for women's choice in everything from childbirth to politics, directly contradicted everything the Third Reich believed. Adolf Hitler supported traditional gender roles and wanted to maintain high birth rates, ideas Sanger decried in her books.

12. HER NIECE WAS PART OF THE INSPIRATION FOR WONDER WOMAN.

Olive Byrne, Sanger's niece, was involved in a polyamorous relationship with Wonder Woman creator William Moulton Marston and his wife, Elizabeth Holloway Marston. Marston credited both Olive and Elizabeth as his muses, according to historian Jill Lepore. In her 2014 book The Secret History of Wonder Woman, Lepore wrote that Marston based part of Wonder Woman's costume on the silver bracelets Olive often wore. Lepore also suggested Sanger herself may have been an influence on the popular comic book character. Feminist movements in the early 1900s often symbolized female oppression with chains, and Sanger was quick to adopt such symbolism with books like Motherhood in Bondage. Wonder Woman's use of chains and ropes as weapons echoed Sanger's vision for female liberation.

13. SHE WAS NOMINATED FOR THE NOBEL PEACE PRIZE 31 TIMES.

Margaret Sanger received 31 nominations for the Nobel Peace Prize between 1953 and 1963. In 1960 alone, she received 20 nominations from 16 university professors and four members of India's parliament (Sanger took several trips to India, where she worked with people like Gandhi to discuss birth control).

14. SHE LIVED JUST LONG ENOUGH TO SEE HER LIFE'S WORK COME TO FRUITION.

Two important legal milestones happened after Sanger founded the American Birth Control League in 1921. In December 1936, the 2nd U.S. Circuit Court of Appeals effectively overturned all federal restrictions on birth control, making it legal for doctors throughout the United States to provide access to contraception. On the state level, contraception was legal in some form or another everywhere except Connecticut, Mississippi, and Massachusetts. In 1965, Griswold v. Connecticut overturned the state laws preventing married women from accessing birth control. Griswold v. Connecticut later served as precedent for cases like Eisenstadt v. Baird (1972), which gave unmarried couples unrestricted access to contraception; Roe v. Wade (1973), which legalized abortion; and Carey v. Population Services International (1977), which made it legal for doctors and pharmacists to distribute contraceptives to minors.

Sanger died on September 6, 1966, about a year after the Supreme Court decided on Griswold v. Connecticut. The next day, Alaska Senator Ernest Gruening spoke about Sanger in Congress. In an address to the president, Gruening said Sanger was "a great woman, a courageous and indomitable person who lived to see one of the most remarkable revolutions of modern times—a revolution which her torch kindled."
