The time lag between the publication of groundbreaking research in a given field and its recognition with a Nobel Prize has grown significantly longer since the 1960s, particularly in Chemistry, Physics, and Physiology or Medicine. Between 2011 and 2019, the average time to receive the prize was over 25 years, according to a report published on September 29 in Nature<\/em>. The average lag was shorter in Physiology or Medicine, at 26 years, and longer in Chemistry, at 30 years.<\/p>\n

This year was no exception, other than for the Physiology or Medicine prize, which honored discoveries published less than 20 years ago. In 2023, the prize amount in the six categories\u2014Physics, Chemistry, Peace, Literature, Economics, and Physiology or Medicine\u2014was 11 million Swedish crowns (approximately R$5 million). There were 11 winners, including four women\u2014the same number as in 2018 and 2020, and only slightly lower than in 2009 when there were five women laureates.<\/p>\n

Physiology or medicine<\/strong>
\nOn October 4, a team led by Santuza Teixeira, a biochemist at the Federal University of Minas Gerais (UFMG), presented research results for a potential vaccine against cutaneous leishmaniasis at a conference of the Brazilian Society of Immunology\u2014leishmaniasis is an infection caused by protozoa that produces lesions on the skin and cartilage. The formulation was tested in mice using messenger RNA (mRNA) to stimulate the rodents\u2019 bodies to produce a protein fragment that triggers their defense system to attack the protozoa. Animals that received the formulation had 10 to 100 times fewer parasites in their lesions compared to those treated with placebo. \u201cIt\u2019s a significant result, but there\u2019s room for improvement,\u201d says biochemist Gabriela Burle Caldas, who presented the data at the conference.<\/p>\n

Two days prior, the Nobel Prize in Physiology or Medicine had been awarded to the researchers who pioneered the development of mRNA-based vaccines. Hungarian biochemist Katalin Karik\u00f3, 68, and American immunologist Drew Weissman, 64, both affiliated with the University of Pennsylvania, shared the prize equally.<\/p>\n

Karik\u00f3 began her scientific career in Hungary and later migrated to the US in the late 1980s. At the University of Pennsylvania, her initial work focused on developing mRNA-based therapies for treating stroke, but she struggled to secure funding. In 1997, she formed a collaboration with Weissman, who was then exploring new strategies for developing a vaccine against the AIDS virus.<\/p>\n

Without Karik\u00f3\u2019s and Weissman\u2019s breakthrough, the development of mRNA vaccines would not have been possible<\/p><\/blockquote>\n

Available vaccines at the time were typically derived from whole pathogens or their proteins to stimulate the defense system\u2019s response. However, they required the cultivation of large quantities of cells. Seeking alternatives, one approach involved mRNA molecules. The concept was to develop a vaccine with laboratory-produced mRNA coding for a protein that triggers an immune response against a specific pathogen. Within the body, the mRNA would reach the cells and initiate the production of the defense-activating protein.<\/p>\n

However, the synthetic version of these molecules proved to be unstable. As soon as it entered the body, it was recognized as an invader and promptly destroyed. Furthermore, it induced intense inflammation that obliterated the very cells it was meant to protect. Karik\u00f3 and Weissman observed that this inflammatory response occurred because the naturally produced mRNA in mammalian cells had a slight chemical alteration absent in the laboratory version. They successfully worked around this issue by modifying the synthetic molecule.<\/p>\n

\u201cTheir discovery paved the way for safe mRNA vaccines with enhanced immunogenicity,\u201d explains microbiologist Lu\u00eds Carlos de Souza Ferreira from the University of S\u00e3o Paulo (USP).<\/p>\n

During the COVID-19 pandemic, the new technology was licensed to pharmaceutical companies Moderna and Pfizer\/BioNTech\u2014Karik\u00f3 has been the senior vice president of BioNTech since 2019\u2014to support the production of two of the most effective vaccines against the novel coronavirus. \u201cWithout Karik\u00f3\u2019s and Weissman\u2019s breakthrough, the development of mRNA vaccines would not have been possible,\u201d says Teixeira from UFMG. Presently, Ferreira\u2019s team at USP is evaluating the performance of a potential mRNA vaccine developed in collaboration with Karik\u00f3\u2019s group to treat cancer caused by the human papillomavirus (HPV) (see<\/em> Pesquisa FAPESP issue n\u00ba 326<\/em><\/a>).<\/p>\n

Physics and chemistry<\/strong>
\nThis year\u2019s Nobel Prizes in Physics and Chemistry were awarded for research that has provided a better understanding of the behavior of matter at the subatomic level.<\/p>\n

French physicists Anne L\u2019Huillier from Lund University, in Sweden, and Pierre Agostini from Ohio State University, in the US, along with Hungarian-Austrian Ferenc Krausz from the Max Planck Institute of Quantum Optics, in Germany, shared the Nobel Prize in Physics for their development of methods to generate attosecond pulses of light.<\/p>\n

An attosecond is equivalent to one billionth of one billionth of a second. Measurements on this timescale can be used to detect when electrons within atoms and molecules move or change energy. For the human senses, rapid movements such as these are perceived as being blurred together. Prior to the work of the trio of physicists, measurements involving light pulses had never gone below the femtosecond range (1 femtosecond equals 1,000 attoseconds).<\/p>\n

\u201cAttosecond physics deals with matter under extreme conditions, using high-intensity lasers and extremely short timescales,\u201d remarks Brazilian physicist Carla Figueira De Morisson Faria from University College London in the UK, who is currently conducting research in this area. \u201cThis field encompasses various branches where real-time control of electrons is gradually becoming a reality.\u201d<\/p>\n

Starting in 1987, seminal research by 65-year-old L\u2019Huillier laid the foundations for attosecond science. In experiments over the following decades, she and her Nobel-winning colleagues characterized and learned to manipulate the phenomena that ultimately enabled them to generate attosecond light pulses. In Austria, 61-year-old Krausz\u2019s group developed a technique to isolate a single light pulse that lasted 650 attoseconds. Meanwhile, in the US, a team led by 82-year-old Agostini, using similar approaches, was able to measure pulses lasting 250 attoseconds.
\nIn electronics, these techniques can be valuable for understanding and controlling how electrons behave in a material. In medicine, they can also be used in diagnostic imaging.<\/p>\n

The Nobel Prize in Chemistry was jointly awarded to 78-year-old Russian physicist Alexei Ekimov at Nanocrystals Technology, 89-year-old American chemist Louis Brus from Columbia University, and 62-year-old Franco-Tunisian chemist Moungi Bawendi from the Massachusetts Institute of Technology (MIT). The trio was recognized for their discovery of quantum dots and ways to synthesize them with precision.<\/p>\n

Quantum dots are extremely minute particles, with diameters in the range of a few nanometers (1 nanometer is one millionth of a millimeter). Their tiny size gives them a unique characteristic: their physical and chemical properties are size-dependent, whereas the properties of larger particles are determined solely by chemical composition. As a result, quantum dots of the same composition but different sizes can emit light in different colors.<\/p>\n

In the 1980s, Ekimov discovered that the color of glass changes with the size of semiconductor quantum dots. Brus observed a similar phenomenon in particles suspended in liquids, during his research on catalytic properties. In the 1990s, Bawendi, who had completed a postdoctoral fellowship under Brus, developed precise methods for synthesizing quantum dots.<\/p>\n

\u201cBlue light is the most difficult to produce,\u201d notes physicist \u00c9der Guidelli from USP\u2019s Ribeir\u00e3o Preto School of Philosophy, Sciences, and Languages and Literature (FFCLRP). In 2017, during a one-year stay at MIT in a lab affiliated with Bawendi, Guidelli successfully engineered zinc selenide nanoparticles to emit blue light. Currently, Guidelli is investigating a different type of nanoparticle in cancer research.<\/p>\n

Maria del Pilar Sotomayor, a Peruvian chemist at S\u00e3o Paulo State University\u2019s (UNESP) Araraquara campus, is exploring the use of quantum dots for cancer diagnostics.<\/p>\n

Economics and peace<\/strong>
\nTwo of this year\u2019s prizes recognized the significant roles played by women in advocacy for women\u2019s rights.<\/p>\n

American economist Claudia Goldin, 77, from Harvard University, received the Nobel Prize in Economics for her research on female participation in the US labor market over the centuries and her contributions to understanding the causes of wage inequality between men and women.<\/p>\n

\u201cWomen are vastly underrepresented in the global labor market and, when they work, they earn less than men. Claudia Goldin has trawled the archives and collected over 200 years of data from the US, allowing her to demonstrate how and why gender differences in earnings and employment rates have changed over time,\u201d wrote the Royal Swedish Academy of Sciences in a press release.<\/p>\n

\u201cGoldin\u2019s contributions were in two key areas: addressing wage and labor market participation disparities between men and women in the US and examining the role of education in explaining the wage gap in the country,\u201d says Naercio Menezes Filho, an economist who heads the FAPESP-funded Center for Applied Research on Early Childhood at INSPER.<\/p>\n

The Nobel Peace Prize was awarded to 51-year-old Iranian Narges Mohammadi. A physicist and activist, she is currently imprisoned in Iran for her advocacy of democratic principles and basic human rights, especially for women\u2014a commitment she has held since her college days.<\/p>\n

\u201cEven in prison, Mohammadi remains a leading figure, a symbol of what it means to be a freedom fighter,\u201d said Norwegian lawyer Berit Reiss-Andersen when announcing the award.<\/p>\n

Literature<\/strong>
\nThe Norwegian writer, playwright, poet, and translator Jon Fosse, 64, received the Nobel Prize in Literature for 2023. The Swedish Academy honored him for his \u201cinnovative plays and prose which give voice to the unsayable,\u201d and for how, \u201cin his radical reduction of language and dramatic action, he exposes human anxiety and ambivalence at its core.\u201d Born in 1959 in Haugesund, Fosse writes in Nynorsk, one of the two official written standards of Norwegian, used by 10% to 15% percent of the population.<\/p>\n

Fosse has written over 50 works, with three books published in Brazil: Melancholy <\/em>(Tordesilhas, 2015), Aliss at the fire<\/em> (Companhia das Letras, 2023), and A shining<\/em> (F\u00f3sforo, 2023). Fosse is renowned in Norway as a playwright. \u201cHe has the largest number of plays to his name after Ibsen,\u201d says Lucas Lazzaretti, a postdoctoral researcher in Swedish literature and drama at the Federal University of Paran\u00e1 (UFPR).<\/p>\n

Prizes that make people laugh and then think <\/strong>
\nEssays on why geologists sometimes lick rocks and studies on the sexual activity of anchovies were some of the winners of this year\u2019s Ig Nobel Prize<\/em><\/p>\n

On September 14, the Ig Nobel Prize ceremony celebrated \u201cachievements that first make people laugh, then make them think.\u201d This year\u2019s edition presented prizes in 10 categories. Below are some of the zany prize-winning projects.<\/p>\n

Jan Zalasiewicz, a British-Polish geologist, won the Chemistry and Geology Ig for explaining why, 200 years ago, geologists lacking technological resources would lick rocks to identify them. In a 2017 essay in The Palaeontology Newsletter<\/em>, Zalasiewicz revisited accounts from Italian mineralogist Giovanni Arduino (1714\u20131795), who could distinguish the taste of different fossiliferous contexts and attribute them to geological and stratigraphic aspects. \u201cThey did geology, at least in part, by taste and it worked for them,\u201d explained Zalasiewicz, who claims to have licked many stones on field trips to determine their attributes before examining them under a magnifying glass.<\/p>\n

The Literature prize went to researchers from France, the UK, Malaysia, and Finland who observed what subjects felt when asked to \u201crepeat a single word many, many, many, many, many times.\u201d The paper, exploring the phenomenon of jamais vu<\/em>, was published in 2021 in Memory<\/em>.<\/p>\n

In Medicine, the prize recognized researchers from the US, Canada, Iran, Vietnam, and Macedonia who used cadavers as a means to explore whether there is an equal number of hairs in each of a person\u2019s two nostrils. Their findings were reported in a 2022 article in the International Journal of Dermatology<\/em>.
