Science in Africa: a continent on the cusp of change

María Teresa Dova describes how an early career move to CERN as the first Latin American scientist to join Europe’s organisation for nuclear research ultimately benefited both her but also the researchers she now works with back home in Argentina.The move to Geneva, Switzerland, where CERN is based, required Dova to pivot from condensed matter physics, the subject of her PhD at the University of La Plata, Argentina, which she gained in 1988. But any misgivings about the move to Europe and switching to a new field were quickly banished by her excitement at working on the L3 Large Electron Positron Collider project, she tells Julie Gould. Dova returned to Argentina two-and-a-half years later, launching the experimental high energy group at La Plata and driving other important collaborations, including the inclusion of Argentina in CERN’s ATLAS particle detector collaboration. She describes how it happened.

A 2021 report by the UNESCO International Institute for Higher Education in Latin America and the Caribbean revealed that only 18% of public universities in the region had female rectors. Vanessa Gottifredi, a biologist and president of Argentina’s Leloir Institute Foundation, a research institute based in Buenos Aires, says this paucity of visible role models for female scientists in the region means that damaging stereotypes are perpetuated.A female, she says, will not be judged harshly for staying at home to handle a family emergency, but will be for being pushy at work, unlike male colleagues. “Women need to hear that they are good, more than men do, because they tend to convince themselves they're not good enough,” she adds.In the penultimate episode of this six-part podcast series about female scientists in Latin America, Gottifredi, who worked abroad for 11 years before returning to Argentina, tells Julie Gould how she aims to empower female colleagues, based on what she witnessed elsewhere.

Fernanda Staniscuaski earned her PhD aged 27. Five years later she had a child. But in common with many scientist mothers, Staniscuaski, a biologist at Brazil’s Federal University of Rio Grande do Sul, saw funding and other career opportunities diminish as she combined motherhood with her professional life. “Of course I did not have as much time as I was used to have. And everything impacted my productivity,” she tells Julie Gould.The Brazilian biologist founded the Parent in Science advocacy movement after talking with other scientist parents. In the fourth episode of this six-part podcast series about Latin American women in science, Staniscuaski lists the movement’s achievements so far, and the challenges that lie ahead.In 2021 Parent in Science won the science outreach category in the Nature Inspiring Women in Science awards, in partnership with the Estée Lauder Companies.

Paleontologists Ana Valenzuela-Toro and Mariana Viglino outline some of the challenges shared by researchers across Latin America. These include funding, language barriers, journal publication fees and conference travel costs. But the two women then list some of the extra burdens faced by female researchers who live and work there, many of which will resonate with female colleagues based elsewhere. “When you are in a room sharing a scientific idea or project, nobody listens to you. Then another person, usually a male researcher, says what you said,” says Valenzuela-Toro, who is based in Caldero, Chile. Mariana Viglino, a Puerto Madryn-based researcher at CONICET, an Argentine government science agency, says the election of far-right governments inevitably results in science funding cuts. “And that means many people having their careers cut. Many research projects that are not going to be able to continue,” she warns.“It makes me feel really hopeless, and really burnt out, and really sad. I really don’t even know how to put it into words. You want to give back to the government who has invested in you. You want to give back to society. You just feel like they are just pushing you out.” Hosted on Acast. See acast.com/privacy for more information.

In 2013 physicist Carolina Brito co-launched Meninas na Ciência (Girls in Science), a program based at Brazil’s Federal University of Rio Grande de Sul.The program exposes girls to university life, including lab visits and meetings with female academics. “There are several girls who have never met someone who has been to university,” says Brita. “It’s beyond a gender problem.”Jessica Germann was one of them. The 19-year-old is about to start an undergraduate physics degree. She tells Julie Gould how writing a school essay about particle physics and a fascination for YouTube science videos helped in her career choices.This episode is the second episode in a six-part Working Scientist podcast series about Latin American women in science.

In her role as Vice Rector for research partnerships and collaboration at the University of the Valley in Guatemala City, Monica Stein works to strengthen science and technology ecosystems in the Central American country and across the wider region.To mark International Women's Day on 8 March, Stein outlines the steps needed to attract girls into science careers. Access to higher education needs to widen, she argues, alongside more robust legal and regulatory frameworks to make research careers more diverse.“We need to inspire other women, we need to mentor other women, we need to be available for conversations,” she says. “We need to tell them it’s okay to say no to a project, because you’re pregnant, just giving birth, or your child is young, which is something that is so common here in Guatemala.”This episode is the first episode in a six-part Working Scientist podcast series about Latin American women in science.

Laure Sione’s postdoctoral research at Imperial College London addresses the sixth of the 17 United Nations SDGs, but, she argues, sanitation also plays a huge role in gender equality (SDG 5) and good health and well being (SDG 3) targets.Sione’s PhD research focused on water management challenges in Kathmandu, but she now focuses on Sub-Saharan Africa and the problems caused by open defecation and excrement-filled pit latrines that are sited too close to the water table, risking contamination.A third option is toilets layered with Tiger Worms. A key advantage is that these take longer to fill up as the worms quickly degrade faeces, but one barrier is getting people to use them in the first place. “It’s like, it’s a gross thing, and they don’t want to think about it. But I think the benefits quickly take over,” she says.Each episode of How to Save Humanity in 17 Goals, a Working Scientist podcast series from Nature Careers, features researchers whose work addresses one or more the targets.

In 2016 the University of Melbourne, Australia, asked for female-only applicants when it advertised three vacancies in its School of Mathematics and Statistics. It repeated the exercise in 2018 and 2019 to fill similar vacancies in physics, chemistry, and engineering and information technology.Elaine Wong and Georgina Such tell the How to Save Humanity in 17 Goals podcast why certain schools wanted only female candidates to apply, and how staff and students reacted to the policy. They also explain what it achieved in terms of addressing the under-representation of female faculty in science, technology, engineering and maths (STEM) subjects.Both Wong, a photonics researcher who was appointed Pro Vice-Chancellor (People and Equity) at the university in 2023, and Such, a polymer chemist and associate professor there, explain how the university’s “affirmative action” strategy is helping to address the fifth of the 17 United National Sustainable Development Goals: to achieve gender equality and empower all women and girls.Each episode in this series, from Nature Careers, features researchers whose work addresses one or more of the targets.

As a child Solomon King Benge loved Eric Laithwaite’s 1974 book The Engineer in Wonderland, based on the mechanical engineer’s 1966 Royal Institution Christmas lectures. After reading it he asked his physics teacher if he and his classmates might try some of Laithwaite’s practical experiments, but was told: “Don’t waste your time with this. This is not important, because it’s not in the curriculum.” The rejection promoted Benge to launch Fundi Bots in 2011. The social education initiative aims to give education a stronger practical focus, a move away from learning by rote in front of a blackboard. Last year it reached 22,000 students, most of them in Uganda, and hopes eventually to cover one million across Africa.Robotics is a key component of the program. Benge recalls one child in northern Uganda who built a sensor-driven robot and was asked what he might do with it. He said: “I think I can now create something that lets the goats out of the pen in the morning so that I don’t have to wake up early.”Benge tells the How to save humanity in 17 goals podcast series: “It was hilarious for us, but a very real testament of once you empower children and make learning meaningful, then they actually begin looking at the practical applications of that learning.”The educator and entrepreneur describes how Fundi Bots addresses SDG 4 and its aim to deliver quality education and lifelong learning for all by 2030.Each episode in the series features researchers whose work addresses one or more the targets.

A drive to reduce suicide mortality rates is a key indicator of the United Nations Sustainable Development Goals. Psychiatrist Shekhar Saxena, who led the World Health Organization’s mental health and substance abuse program after working in clinical practice for more than two decades, says that although progress is being made, a worryingly high number of young people are choosing to end their lives.“They have to struggle through the school education, competitive examinations, then they have to struggle for a job,” says Saxena, who now teaches at Harvard Chan School of Public Health, in Cambridge, Massachusetts. “And many young people decide that dying is easier than struggling through for many years, which is very sad. It reflects the society that we live in where a young person does not feel that life is worth living.”In the third episode How to Save Humanity in 17 Goals podcast series, Saxena welcomes the inclusion of mental health in SDG 3 and its aim to ensure healthy lives and promote well-being for all at all ages. But he points out that countries on average spend less than 2% of their health budget on mental health, when the disease burden is around 10%. Each episode in the series features researchers whose work addresses one or more the targets.
