Despite the rules, a Nobel Prize in medicine has been awarded posthumously

Read more about the backstory on the 2025 Nobel Prize for immune system work

A trio of scientists won the Nobel in Physiology or Medicine that year, but they performed their award-worthy work beginning about two decades before winning the prize. This announcement includes details about the science and notes that the three scientists will equally share the 11 million Swedish kronor (almost $1.2M).

The Nobel Prize remains science's top honor despite limits and inequities

Each October, a few scientists gain global fame when told they’ve won a Nobel Prize—a century-old award founded by Alfred Nobel to recognize major achievements. While the prizes boost attention and prestige for winners, they exclude many deserving scientists due to rigid rules.

How Nobel Prize-winning research unraveled why the immune system doesn't always attack itself

The 2025 Nobel Prize was awarded to scientists who discovered how immune system soldiers are typically stopped from attacking healthy tissue. The work furthered autoimmune understanding and cancer therapies.

Only allowing three recipients causes the Nobel Prize to overlook team discoveries

While science has grown more inclusive and collaborative, the Nobel Prize system still struggles with outdated practices, such as secrecy and a rigid limit on awardees. This restriction sidelines many deserving scientists, especially in complex projects like the human genome or gravitational waves.

Some Nobel laureates have expressed beliefs in pseudoscience after winning

Examples of the phenomenon, known as Nobelitis or Nobel disease, include promoting psychic research, harmful practices like eugenics, and seeing talking raccoons. Increased external pressures after a win and a greater spotlight may contribute to developing or exposing these beliefs.

The Nobel Peace Prize is sometimes awarded to inspire ideals, not honor achievements

Critics argue this approach has led to regrettable choices, such as honoring Yasser Arafat despite his militant past or Barack Obama before he established a peace legacy. Committee member Kåre Kristiansen resigned in protest after Arafat was named a laureate in 1994.

The discovery of insulin led to a controversial Nobel Prize in 1923

For centuries, Type 1 diabetes was fatal. The 1920s "discovery" of insulin netted two of its creators—Frederick Banting and his boss, John Macleod—a Nobel prize. Separately, the German doctor Georg Zuelzer synthesized an effective version of the life-saving drug years earlier but was interrupted by World War I.

The Nobel Prizes honor global achievements in science, literature, and peace efforts

Established by Alfred Nobel’s will, the Nobel Prizes have been awarded since 1901 to individuals and organizations making major contributions to humanity. Although often grouped with the five original prizes, the economics award was added later by Sweden’s central bank in 1968 and isn't technically a Nobel Prize.

As of 2026, the Pontifical Academy of Sciences, which advises the pope on scientific matters, has included 90 Nobel laureates among its members.

Being nominated for a Nobel Peace Prize is easy—winning one is not

Hundreds of people are nominated yearly, including controversial figures like Benito Mussolini and Adolf Hitler, since nominations can come from professors or politicians worldwide. Le Duc Tho refused the 1973 prize jointly awarded to him and Henry Kissinger, citing ongoing conflict in Vietnam.

Critics say Nobel Prizes need updating to reflect how science and society work today

The rules still favor individuals over teams and may reflect outdated views on who does science. In 2013, the Nobel Prize in physics went to two theorists, even though over 5,000 scientists helped confirm the Higgs boson.

Non-Nobel Prize awards recognize topics outside of chemistry, physics and medicine

Established in 2002, the Abel Prize awards $750,000 to a mathematician for pioneering scientific achievements, while the $1M Turing Award honors contributions in computer science. Additional prizes in earth science, engineering, environmental science and policy, astrophysics, nanoscience and neuroscience have also been established.

Why a Nobel Prize winner was awarded 30 years of free beer

Niels Bohr, the Danish physicist who won the Nobel Prize for Physics in 1922, moved into the Carlsberg Honorary Residence in 1932 and was entitled to free delivery of Carlsberg beer for as long as he lived there. He did so until he died in 1962.

Alexander Fleming, Howard Florey, and Ernst Chain received the 1945 Nobel Prize in Physiology or Medicine for discovering and developing penicillin.

X-rays earned the very first Nobel Prize in physics for revealing hidden worlds

In 1895, Wilhelm Conrad Röntgen discovered X-rays, which could pass through solid objects and make unseen structures visible. Today’s X-ray tools continue to advance science and medicine, including capturing real-time images of proteins.

The Ig Nobel Prize is a satirical version of the Nobel Prize and aims to engage broader audiences with science by spotlighting scientific achievements that make people laugh before they think.

In 2016, Bob Dylan won the Nobel Prize for his lyrics

Rock legend Bob Dylan’s 2016 Nobel Prize was a surprise in the literary world. A rock lyricist had never been awarded the distinction. Dylan explains his affection for literary giants like Herman Melville and Homer, connecting his writing, and the rock ‘n’ roll of his youth, to the literary tradition.

The Nobel Prize committee was not enthusiastic about selecting John Steinbeck, whom they considered past his prime.

The Pius XI Medal—named after the pope who rebranded the Pontifical Academy of Sciences in 1936—has been awarded every two years to a promising scientist under 45.

Nobel Prizes in science have heavily favored male, North American, and European scientists

Most science laureates come from established academic institutions, and limited outreach and nomination rules have biased against researchers from low- and middle-income countries. As of 2024, China ranks among the world’s top scientific contributors, but has only won 10 Nobel Prizes in the sciences.

By reprogramming adult cells into embryonic-like stem cells, scientists might be able to rejuvenate tissues and treat age-related diseases—though ethical and safety concerns remain.

Robert Koch won the Nobel for his tuberculosis work, but he also pioneered cholera research

Koch was one of the first scientists to isolate the bacterium that causes cholera while investigating an outbreak in Egypt in 1883. He went on to advise about rules to control cholera outbreaks, which formed the basis of the disease control approaches and water hygiene techniques still used today.

Marie Curie's research in radioactivity made her the first woman to win a Nobel Prize

Overcoming social and academic barriers, Curie's realization that radiation resulted from an intrinsic property of atoms reframed scientific understanding of the phenomenon. Her subsequent work in discovering two new elements—polonium and radium—earned her a second Nobel Prize.

Marie Curie pioneered radioactivity research, for which she won two Nobel Prizes

Marie Curie and her husband isolated polonium and radium despite poor lab conditions and financial hardship. President Harding, on behalf of the women of America, presented her with one gram of radium in 1921 in recognition of her service to science.

Chinese scientists transplanted a pig lung into a human being—but it had to be removed

In August 2025, Chinese scientists transplanted a pig lung into a brain-dead person, a common research step for this type of experimental work. Researchers used CRISPR technology to alter six proteins in the pig genes to make the organ seem less foreign to the human immune system. Within a day there were indications the organ wasn’t functioning well and that the person’s body was rejecting it. Scientists ended the experiment after nine days.

Alfred Nobel invented dynamite and later used his fortune to fund peace prizes

The woman erased from the DNA breakthrough

Rosalind Franklin captured “Photo 51,” the key to DNA’s double helix. Her data, shared without her knowledge, helped Watson and Crick win a Nobel. She never got the prize, but today, her role in unlocking life’s blueprint is finally recognized.

After the patient died, a latent pig virus was discovered inside his xenotransplant

Researchers studying the death of David Bennett Sr., the first gene-edited pig heart transplant patient, discovered potential factors that may have contributed to his demise. One finding is that there was a latent virus, called porcine cytomegalovirus (PCMV), in the pig heart, which may have contributed to dysfunction of the transplant.
