Co-founder of billion-dollar AI for autonomous driving company and Cambridge alumnus wins Princess Royal Silver Medal
Wayve is one of the UK’s most valuable deep tech startups, backed by more than $1 billion in funding. Alex Kendall co-founded the company in 2017 following his PhD at the University of Cambridge, where he pioneered a contrarian approach to self-driving cars.
At a time when the industry relied heavily on rule-based systems, maps and multiple sensors, he proposed a different vision powered by deep learning—where a single neural network could learn to drive from raw data without human intervention.
Wayve’s approach creates a general-purpose driving intelligence that can adapt to new environments. Its models are trained on tens of petabytes of real-world data from its team of safety drivers. Wayve tests its models in both real-world driving settings and in simulation. Real-world testing exposes AI to diverse conditions, while simulation enables efficient, large-scale validation.
Synthetic data on rare or unseen scenarios are used to train their technology to safely navigate the real world. Wayve tests these safety-critical scenarios, such as near collisions or unpredictable pedestrian behaviour, using a cutting-edge generative world model.
Wayve’s autonomous cars have been navigating the complex streets of London since 2019, overseen by legally required safety drivers. Last year they expanded to San Francisco and have also been testing these cars in Stuttgart, and Japan. The company plans to license its technology to car manufacturers, with Nissan set to integrate Wayve’s AI to support driver assistance into its vehicles by 2027.
The engineering team have also built the first language-driving model tested on public roads. LINGO opens up communication with the robot and can narrate its driving and answer questions. That means Wayve’s engineers (and eventually passengers) can communicate with the AI and ask it to explain decisions or drive in a certain way.
He sees autonomous driving as a launchpad for a broader revolution in embodied AI, with applications in robotics, manufacturing, and healthcare. “Bringing AI into the physical world in a way that it can interact with us, is real – is tangible,” explains Kendall, “I think it’s going to be the biggest transformation we go through in our lifetimes.”

Celebrating Lord Sainsbury of Turville’s ‘selfless’ service as Chancellor
At a reception at the Vice-Chancellor’s Lodge this week, which celebrated his service to the University, Lord Sainsbury talked fondly about his own time as a student at Cambridge, and said: “It has been a great honour and pleasure to be Chancellor of the University of Cambridge, one of the world’s greatest universities.
“Over the years, I have watched with awe how the University has produced an endless stream of brilliant research and an enlightened education for its undergraduates and postgraduates, and I hope that by being Chancellor, and in a number of other ways, I have to some extent repaid my debt to the University. I will always look back at my time as Chancellor with the greatest pleasure.”
The Vice-Chancellor, Professor Deborah Prentice, paid a warm tribute to the Chancellor and thanked him for his service and contribution to the life of the University, and his support for her.
In a recent edition of CAM – the University's alumni magazine – other friends and former colleagues recounted the unique qualities Lord Sainsbury has brought to the post during almost a decade and a half of unwavering commitment.
With high-level experience in government and industry alike, Lord Sainsbury has been a highly effective advocate for the best interests of the University on both the national and global stage. “He’s a man of great ability and thoughtfulness,” says Professor Mike Proctor, 2013-2023 Provost of King’s College, Lord Sainsbury’s alma mater. “He’s very well connected in both the public and private sectors. And that’s been very helpful to the University at large.”
Professor Stephen Toope, the 346th Vice-Chancellor, says that although the role is technically ceremonial, Lord Sainsbury was always willing to go above and beyond. “If I asked him to do something for the University – connect me with the right person, give me a piece of advice – he always did it. He was very generous in making introductions, and saw his role as trying to strengthen the University where he could. And that was largely by supporting the people who’d been asked to do the big jobs – on the Council and in the leadership of Cambridge.”
As a former Minister of Science and Innovation, Lord Sainsbury has brought a wealth of experience to the University. But he has also brought his own love of research and innovation to bear, as Rebecca Simmons, the VC’s former Chief of Staff and now COO of quantum computing company Riverlane, saw first-hand. “He liked to get into the detail beforehand, so he could make good connections with people,” she remembers. “And sometimes, he would come back to see the same people over several years. For example, he stayed in touch with the CEO of Endomag, a cancer diagnostics spinout, and made a point of going back to meet them at key moments. In fact, accompanying him on visits was one of the most fun parts of my job.”
Dr Regina Sachers, former Head of the Vice-Chancellor’s Office and now Director of Governance and Compliance, agrees. “He found it easy to connect with academics because he was genuinely interested in the work. He would always ask very informed questions, and would frequently offer his card and put people in touch with his own connections. It felt like a very genuine and low-key approach.”
The role of Vice-Chancellor can be lonely, says Sir Leszek Borysiewicz, Vice-Chancellor 2010-17: often, the only person you can talk to is the Chancellor. “And Lord Sainsbury always made himself available. He was a friend, a mentor, an adviser. We had differences of opinion, but we could always talk. Having that open debate meant you could road-test the strength of an argument – and, sometimes, backpedal, because he’d made some very valid points that were critical for the University. And I can attest that during my time as Vice-Chancellor, he was always there for the difficult issues. He was quiet and understated, but very thoughtful and very wise – and never interfered with the executive functions that the Vice-Chancellor has to exercise.”
“Lord Sainsbury does not have an agenda of his own: he seeks to do what the University needs, and always has its best interests at heart,” says current Vice-Chancellor Professor Deborah Prentice. “He approaches the job with selflessness and the mentality of a public servant. I like the fact that sometimes he just turns up to things; he’s such a curious and interested person. I think he very much embodies the values of the University.”
Professor Toope says that he has always been struck by Lord Sainsbury’s “complete lack of pomposity. Some people think they are the role. He always understood that the role is the role: he just happened to be occupying it for a period. And he brought a personal and political integrity to it.”
The election for Lord Sainsbury’s successor as Chancellor takes place next month.

AI art protection tools still leave creators at risk, researchers say
So say a team of researchers who have uncovered significant weaknesses in two of the art protection tools most used by artists to safeguard their work.
According to their creators, Glaze and NightShade were both developed to protect human creatives against the invasive uses of generative artificial intelligence.
The tools are popular with digital artists who want to stop artificial intelligence models (like the AI art generator Stable Diffusion) from copying their unique styles without consent. Together, Glaze and NightShade have been downloaded almost nine million times.
But according to an international group of researchers, these tools have critical weaknesses that mean they cannot reliably stop AI models from training on artists’ work.
The tools add subtle, invisible distortions (known as poisoning perturbations) to digital images. These ‘poisons’ are designed to confuse AI models during training. Glaze takes a passive approach, hindering the AI model’s ability to extract key stylistic features. NightShade goes further, actively corrupting the learning process by causing the AI model to associate an artist’s style with unrelated concepts.
But the researchers have created a method – called LightShed – that can bypass these protections. LightShed can detect, reverse-engineer and remove these distortions, effectively stripping away the poisons and rendering the images usable again for Generative AI model training.
It was developed by researchers at the University of Cambridge along with colleagues at the Technical University Darmstadt and the University of Texas at San Antonio. The researchers hope that by publicising their work – which will be presented at the USENIX Security Symposium, a major security conference, in August – they can let creatives know that there are major issues with art protection tools.
LightShed works through a three-step process. It first identifies whether an image has been altered with known poisoning techniques.
In a second, reverse engineering step, it learns the characteristics of the perturbations using publicly available poisoned examples. Finally, it eliminates the poison to restore the image to its original, unprotected form.
In experimental evaluations, LightShed detected NightShade-protected images with 99.98% accuracy and effectively removed the embedded protections from those images.
“This shows that even when using tools like NightShade, artists are still at risk of their work being used for training AI models without their consent,” said first author Hanna Foerster from Cambridge’s Department of Computer Science and Technology, who conducted the work during an internship at TU Darmstadt.
Although LightShed reveals serious vulnerabilities in art protection tools, the researchers stress that it was developed not as an attack on them – but rather an urgent call to action to produce better, more adaptive ones.
“We see this as a chance to co-evolve defenses,” said co-author Professor Ahmad-Reza Sadeghi from the Technical University of Darmstadt. “Our goal is to collaborate with other scientists in this field and support the artistic community in developing tools that can withstand advanced adversaries.”
The landscape of AI and digital creativity is rapidly evolving. In March this year, OpenAI rolled out a ChatGPT image model that could instantly produce artwork in the style of Studio Ghibli, the Japanese animation studio.
This sparked a wide range of viral memes – and equally wide discussions about image copyright, in which legal analysts noted that Studio Ghibli would be limited in how it could respond to this since copyright law protects specific expression, not a specific artistic ‘style’.
Following these discussions, OpenAI announced prompt safeguards to block some user requests to generate images in the styles of living artists.
But issues over generative AI and copyright are ongoing, as highlighted by the copyright and trademark infringement case currently being heard in London’s high court.
Global photography agency Getty Images is alleging that London-based AI company Stability AI trained its image generation model on the agency’s huge archive of copyrighted pictures. Stability AI is fighting Getty’s claim and arguing that the case represents an “overt threat” to the generative AI industry.
And earlier this month, Disney and Universal announced they are suing AI firm Midjourney over its image generator, which the two companies said is a “bottomless pit of plagiarism.”
“What we hope to do with our work is to highlight the urgent need for a roadmap towards more resilient, artist-centred protection strategies,” said Foerster. “We must let creatives know that they are still at risk and collaborate with others to develop better art protection tools in future.”

Autonomous bus trial will carry passengers between Eddington and Cambridge West
A 15-seater autonomous bus will operate between Madingley Road Park & Ride, and around the University's Eddington neighbourhood and Cambridge West Innovation District.
The early phase of the trial, following extensive virtual and on-road testing, starts on Tuesday 24 June with a limited number of morning and afternoon runs each Monday-Friday.
The trial passenger service is free and will enhance local connections, improving access to places of work and study, as well as community and sports facilities for those living and working in the area.
Dan Clarke, Head of Innovation and Technology at the Greater Cambridge Partnership, said: "This is an exciting milestone, but it’s just the beginning. People may have already seen the bus going around Eddington and Cambridge West from Madingley Park & Ride recently, as, after the extensive on-track training with the drivers, we’ve been running the bus on the road without passengers to learn more about how other road-users interact with the technology. We’re now moving gradually to the next stage of this trial by inviting passengers to use Connector.
"As with all new things, our aim is to introduce this new technology in a phased way that balances the trialling of these new systems with safety and the passenger experience. This will ensure we can learn more about this technology and showcase the potential for self-driving vehicles to support sustainable, reliable public transport across Cambridge."
The vehicle is operated by Whippet Coaches using autonomous technology from Fusion Processing.
Professor Anna Philpott, Pro-Vice-Chancellor for Resources and Operations at the University of Cambridge, said "Innovation and research that contributes to society is at the heart of the University’s mission, and this trial aligns with our vision for sustainable and pioneering transport solutions for everyone travelling to and from our sites. Cambridge West Innovation District and Eddington are fitting locations for such an ambitious and forward-thinking project."
A full-scale launch of two full-size autonomous buses on a second route to the Cambridge Biomedical Campus will begin later this year.
The Connector trial is part of a national Centre for Connected and Autonomous Vehicles (CCAV) programme backed by the UK Government to explore how autonomous buses can be safely and effectively integrated into public transport systems.
All vehicles are supported by trained safety drivers at all times and have already undergone digital simulation and rigorous on-road testing.

Rubin Observatory reveals first images
The Rubin Observatory, jointly funded by the US National Science Foundation and the US Department of Energy’s Office of Science, has released its first imagery, showing cosmic phenomena at an unprecedented scale.
In just over 10 hours of test observations, the NSF-DOE Rubin Observatory has already captured millions of galaxies and Milky Way stars and thousands of asteroids. The imagery is a small preview of the Rubin Observatory’s upcoming 10-year scientific mission to explore and understand some of the universe's biggest mysteries.
Located on a mountaintop in Chile, the Rubin Observatory will repeatedly scan the sky for 10 years and create an ultra-wide, ultra-high-definition time-lapse record of our universe. The region in central Chile is favoured for astronomical observations because of its dry air and dark skies, and allows for an ideal view of the Milky Way’s centre.
The facility is set to achieve ‘first light,’ or make the first scientific observations of the Southern Hemisphere’s sky using its 8.4-meter Simonyi Survey Telescope, on 4 July.
UK astronomers, including from the University of Cambridge, are celebrating their role in the most ambitious sky survey to date.
“We will be looking at the universe in a way that we have never done before, and this exploration is bound to throw up surprises that we never imagined,” said Professor Hiranya Peiris from Cambridge’s Institute of Astronomy.
Enabled by an investment of £23 million from the Science and Technology Facilities Council (STFC), UK astronomers and software developers have been preparing the hardware and software needed to analyse the petabytes of data that the survey will produce to enable groundbreaking science that will enhance our understanding of the universe.
The UK is the second largest international contributor to the multinational project, putting UK astronomers at the forefront when it comes to exploiting this unique window on the Universe.
The UK is also playing a significant role in the management and processing of the unprecedented amounts of data. The UK will host one of three international data facilities and process around 1.5 million images, capturing around 10 billion stars and galaxies. When complete, the full 10-year survey is expected to rack up 500 petabytes of date – the same storage as half-a-million 4K Hollywood movies.
The UK’s science portal for the international community is capable of connecting around 1,500 astronomers with UK Digital Research Infrastructure to support the exploitation of this uniquely rich and detailed view of the Universe.
More than two decades in the making, Rubin is the first of its kind: its mirror design, camera size and sensitivity, telescope speed, and computing infrastructure are each in an entirely new category. Over the next 10 years, Rubin will perform the Legacy Survey of Space and Time (LSST) using the LSST Camera and the Simonyi Survey Telescope.
By repeatedly scanning the sky for 10 years, the observatory will deliver a treasure trove of discoveries: asteroids and comets, pulsating stars, and supernova explosions. Science operations are expected to start towards the end of 2025.
“UK researchers have been contributing to the scientific and technical preparation for the Rubin LSST for more than ten years,” said Professor Bob Mann from the University of Edinburgh, LSST:UK Project Leader. “These exciting First Look images show that everything is working well and reassure us that we have a decade’s worth of wonderful data coming our way, with which UK astronomers will do great science.”

Rubin Observatory reveals first images
The Rubin Observatory, jointly funded by the US National Science Foundation and the US Department of Energy’s Office of Science, has released its first imagery, showing cosmic phenomena at an unprecedented scale.
In just over 10 hours of test observations, the NSF-DOE Rubin Observatory has already captured millions of galaxies and Milky Way stars and thousands of asteroids. The imagery is a small preview of the Rubin Observatory’s upcoming 10-year scientific mission to explore and understand some of the universe's biggest mysteries.
Located on a mountaintop in Chile, the Rubin Observatory will repeatedly scan the sky for 10 years and create an ultra-wide, ultra-high-definition time-lapse record of our universe. The region in central Chile is favoured for astronomical observations because of its dry air and dark skies, and allows for an ideal view of the Milky Way’s centre.
The facility is set to achieve ‘first light,’ or make the first scientific observations of the Southern Hemisphere’s sky using its 8.4-meter Simonyi Survey Telescope, on 4 July.
UK astronomers, including from the University of Cambridge, are celebrating their role in the most ambitious sky survey to date.
“We will be looking at the universe in a way that we have never done before, and this exploration is bound to throw up surprises that we never imagined,” said Professor Hiranya Peiris from Cambridge’s Institute of Astronomy.
Enabled by an investment of £23 million from the Science and Technology Facilities Council (STFC), UK astronomers and software developers have been preparing the hardware and software needed to analyse the petabytes of data that the survey will produce to enable groundbreaking science that will enhance our understanding of the universe.
The UK is the second largest international contributor to the multinational project, putting UK astronomers at the forefront when it comes to exploiting this unique window on the Universe.
The UK is also playing a significant role in the management and processing of the unprecedented amounts of data. The UK will host one of three international data facilities and process around 1.5 million images, capturing around 10 billion stars and galaxies. When complete, the full 10-year survey is expected to rack up 500 petabytes of date – the same storage as half-a-million 4K Hollywood movies.
The UK’s science portal for the international community is capable of connecting around 1,500 astronomers with UK Digital Research Infrastructure to support the exploitation of this uniquely rich and detailed view of the Universe.

Cosmic signal from the very early universe will help astronomers detect the first stars
Now, an international group of astronomers led by the University of Cambridge have shown that we will be able to learn about the masses of the earliest stars by studying a specific radio signal – created by hydrogen atoms filling the gaps between star-forming regions – originating just a hundred million years after the Big Bang.
By studying how the first stars and their remnants affected this signal, called the 21-centimetre signal, the researchers have shown that future radio telescopes will help us understand the very early universe, and how it transformed from a nearly homogeneous mass of mostly hydrogen to the incredible complexity we see today. Their results are reported in the journal Nature Astronomy.
“This is a unique opportunity to learn how the universe’s first light emerged from the darkness,” said co-author Professor Anastasia Fialkov from Cambridge’s Institute of Astronomy. “The transition from a cold, dark universe to one filled with stars is a story we’re only beginning to understand.”
The study of the universe’s most ancient stars hinges on the faint glow of the 21-centimetre signal, a subtle energy signal from over 13 billion years ago. This signal, influenced by the radiation from early stars and black holes, provides a rare window into the universe’s infancy.
Fialkov leads the theory group of REACH (the Radio Experiment for the Analysis of Cosmic Hydrogen). REACH is a radio antenna and is one of two major projects that could help us learn about the Cosmic Dawn and the Epoch of Reionisation, when the first stars reionised neutral hydrogen atoms in the universe.
Although REACH, which captures radio signals, is still in its calibration stage, it promises to reveal data about the early universe. Meanwhile, the Square Kilometre Array (SKA)—a massive array of antennas under construction—will map fluctuations in cosmic signals across vast regions of the sky.
Both projects are vital in probing the masses, luminosities, and distribution of the universe's earliest stars. In the current study, Fialkov – who is also a member of the SKA – and her collaborators developed a model that makes predictions for the 21-centimetre signal for both REACH and SKA, and found that the signal is sensitive to the masses of first stars.
“We are the first group to consistently model the dependence of the 21-centimetre signal of the masses of the first stars, including the impact of ultraviolet starlight and X-ray emissions from X-ray binaries produced when the first stars die,” said Fialkov, who is also a member of Cambridge’s Kavli Institute for Cosmology. “These insights are derived from simulations that integrate the primordial conditions of the universe, such as the hydrogen-helium composition produced by the Big Bang.”
In developing their theoretical model, the researchers studied how the 21-centimetre signal reacts to the mass distribution of the first stars, known as Population III stars. They found that previous studies have underestimated this connection as they did not account for the number and brightness of X-ray binaries – binary systems made of a normal star and a collapsed star – among Population III stars, and how they affect the 21-centimetre signal.
Unlike optical telescopes like the James Webb Space Telescope, which capture vivid images, radio astronomy relies on statistical analysis of faint signals. REACH and SKA will not be able to image individual stars, but will instead provide information about entire populations of stars, X-ray binary systems and galaxies.
“It takes a bit of imagination to connect radio data to the story of the first stars, but the implications are profound,” said Fialkov.
“The predictions we are reporting have huge implications for our understanding of the nature of the very first stars in the Universe,” said co-author Dr Eloy de Lera Acedo, Principal Investigator of the REACH telescope and PI at Cambridge of the SKA development activities. “We show evidence that our radio telescopes can tell us details about the mass of those first stars and how these early lights may have been very different from today’s stars.
“Radio telescopes like REACH are promising to unlock the mysteries of the infant Universe, and these predictions are essential to guide the radio observations we are doing from the Karoo, in South Africa.”

Placenta and hormone levels in the womb may have been key driver in human evolution
Dr Alex Tsompanidis, senior researcher at the Autism Research Centre in the University of Cambridge, and the lead author of this new study, said: “Small variations in the prenatal levels of steroid hormones, like testosterone and oestrogen, can predict the rate of social and cognitive learning in infants and even the likelihood of conditions such as autism. This prompted us to consider their relevance for human evolution.”
One explanation for the evolution of the human brain may be in the way humans adapted to be social. Professor Robin Dunbar, an Evolutionary Biologist at the University of Oxford and joint senior author of this new study said: “We’ve known for a long time that living in larger, more complex social groups is associated with increases in the size of the brain. But we still don’t know what mechanisms may link these behavioural and physical adaptations in humans.”
In this new paper, published today in Evolutionary Anthropology, the researchers now propose that the mechanism may be found in prenatal sex steroid hormones, such as testosterone or oestrogens, and the way these affect the developing brain and behaviour in humans.
Using ‘mini-brains’ – clusters of human neuronal cells that are grown in a petri dish from donors’ stem cells – other scientists have been able to study, for the first time, the effects of these hormones on the human brain. Recent discoveries have shown that testosterone can increase the size of the brain, while oestrogens can improve the connectivity between neurons.
In both humans and other primates such as chimpanzees and gorillas, the placenta can link the mother’s and baby’s endocrine systems to produce these hormones in varying amounts.
Professor Graham Burton, Founding Director of the Loke Centre of Trophoblast Research at the University of Cambridge and coauthor of the new paper, said: “The placenta regulates the duration of the pregnancy and the supply of nutrients to the fetus, both of which are crucial for the development of our species’ characteristically large brains. But the advantage of human placentas over those of other primates has been less clear.”
Two previous studies show that levels of oestrogen during pregnancy are higher in human pregnancies than in other primate species.
Another characteristic of humans as a species is our ability to form and maintain large social groups, larger than other primates and other extinct species, such as Neanderthals. But to be able to do this, humans must have adapted in ways that maintain high levels of fertility, while also reducing competition in large groups for mates and resources.
Prenatal sex steroid hormones, such as testosterone and oestrogen, are also important for regulating the way males and females interact and develop, a process known as sex differentiation. For example, having higher testosterone relative to oestrogen leads to more male-like features in anatomy (e.g., in physical size and strength) and in behaviour (e.g., in competition).
But in humans, while these on-average sex differences exist, they are reduced, compared to our closest primate relatives and relative to other extinct human species (such as the Neanderthals). Instead, anatomical features that are specific to humans appear to be related more to aspects of female rather than male biology, and to the effects of oestrogens (e.g., reduced body hair, and a large ratio between the second and fourth digit).
The researchers propose that the key to explain this may lie again with the placenta, which rapidly turns testosterone to oestrogens, using an enzyme called aromatase. Recent discoveries show that humans have higher levels of aromatase compared to macaques, and that males may have slightly higher levels compared to females.
Bringing all these lines of evidence together, the authors propose that high levels of prenatal sex steroid hormones in the womb, combined with increased placental function, may have made human brains larger and more interconnected. At the same time, a lower ratio of androgens (like testosterone) to oestrogens may have led to reductions in competition between males, while also improving fertility in females, allowing humans to form larger, more cohesive social groups.
Professor Simon Baron-Cohen, Director of the Autism Research Centre at the University of Cambridge and joint senior author on the paper, said: “We have been studying the effects of prenatal sex steroids on neurodevelopment for the past 20 years. This has led to the discovery that prenatal sex steroids are important for neurodiversity in human populations. This new hypothesis takes this further in arguing that these hormones may have also shaped the evolution of the human brain.”
Dr Tsompanidis added: “Our hypothesis puts pregnancy at the heart of our story as a species. The human brain is remarkable and unique, but it does not develop in a vacuum. Adaptations in the placenta and the way it produces sex steroid hormones may have been crucial for our brain’s evolution, and for the emergence of the cognitive and social traits that make us human.”

Learning to thrive in diverse African habitats allowed early humans to spread across the world
Today, all non-Africans are known to have descended from a small group of people that ventured into Eurasia around 50,000 years ago. However, fossil evidence shows that there were numerous failed dispersals before this time that left no detectable traces in living people.
In a new study published today in the journal in Nature, scientists say that from around 70,000 years ago, early humans began to exploit different habitat types in Africa in ways not seen before.
At this time, our ancestors started to live in the equatorial forests of West and Central Africa, and in the Sahara and Sahel desert regions of North Africa, where they encountered a range of new environmental conditions.
As they adapted to life in these diverse habitats, early humans gained the flexibility to tackle the range of novel environmental conditions they would encounter during their expansion out of Africa.
This increase in the human niche may have been the result of social adaptations, such as long-distance social networks, which allowed for an increase in cultural exchange. The process would have been self-reinforcing: as people started to inhabit a wider proportion of the African continent, regions previously disconnected would have come into contact, leading to further exchanges and possibly even greater flexibility. The final outcome was that our species became the ultimate generalist, able to tackle a wider range of environments.
Andrea Manica, Professor of Evolutionary Ecology in the University of Cambridge’s Department of Zoology, who co-led the study with Professor Eleanor Scerri from the Max Plank Institute of Bioanthropology in Germany, said: “Around 70,000-50,000 years ago, the easiest route out of Africa would have been more challenging than during previous periods, and yet this expansion was big - and ultimately successful.”
Manica added: “It’s incredibly exciting that we were able to look back in time and pinpoint the changes that enabled our ancestors to successfully migrate out of Africa.”
Dr Emily Hallett of Loyola University Chicago, co-lead author of the study, said: “We assembled a dataset of archaeological sites and environmental information covering the last 120,000 years in Africa. We used methods developed in ecology to understand changes in human environmental niches - the habitats humans can use and thrive in - during this time.”
Dr Michela Leonardi at the University of Cambridge and London’s Natural History Museum, the study’s other lead author, said: “Our results showed that the human niche began to expand significantly from 70,000 years ago, and that this expansion was driven by humans increasing their use of diverse habitat types, from forests to arid deserts.”
Many explanations for the uniquely successful dispersal out of Africa have previously been made, from technological innovations, to immunities granted by interbreeding with Eurasian hominins. But there is no evidence of technological innovation, and previous interbreeding does not appear to have helped the long-term success of previous attempts to spread out of Africa.
“Unlike previous humans dispersing out of Africa, those human groups moving into Eurasia after around 60-50,000 years ago were equipped with a distinctive ecological flexibility as a result of coping with climatically challenging habitats,” said Scerri. “This likely provided a key mechanism for the adaptive success of our species beyond their African homeland.”
Previous human dispersals out of Africa - which were not successful in the long term - seem to have happened during particularly favourable windows of increased rainfall in the Saharo-Arabian desert belt, which created ‘green corridors’ for people to move into Eurasia.
The environmental flexibility developed in Africa from around 70,000 years ago ultimately resulted in modern humans’ unique ability to adapt and thrive in diverse environments, and to cope with varying environmental conditions throughout life.

Before the ‘Out of Africa’ migration that led our ancestors into Eurasia and beyond, human populations learned to adapt to new and challenging habitats including African forests and deserts, which was key to the long-term success of our species’ dispersal.

In a new study published today in the journal in Nature, scientists say that from around 70,000 years ago, early humans began to exploit different habitat types in Africa in ways not seen before.
At this time, our ancestors started to live in the equatorial forests of West and Central Africa, and in the Sahara and Sahel desert regions of North Africa, where they encountered a range of new environmental conditions.
As they adapted to life in these diverse habitats, early humans gained the flexibility to tackle the range of novel environmental conditions they would encounter during their expansion out of Africa.
This increase in the human niche may have been the result of social adaptations, such as long-distance social networks, which allowed for an increase in cultural exchange. The process would have been self-reinforcing: as people started to inhabit a wider proportion of the African continent, regions previously disconnected would have come into contact, leading to further exchanges and possibly even greater flexibility. The final outcome was that our species became the ultimate generalist, able to tackle a wider range of environments.
Andrea Manica, Professor of Evolutionary Ecology in the University of Cambridge’s Department of Zoology, who co-led the study with Professor Eleanor Scerri from the Max Plank Institute of Bioanthropology in Germany, said: “Around 70,000-50,000 years ago, the easiest route out of Africa would have been more challenging than during previous periods, and yet this expansion was big - and ultimately successful.”
Manica added: “It’s incredibly exciting that we were able to look back in time and pinpoint the changes that enabled our ancestors to successfully migrate out of Africa.”
Dr Emily Hallett of Loyola University Chicago, co-lead author of the study, said: “We assembled a dataset of archaeological sites and environmental information covering the last 120,000 years in Africa. We used methods developed in ecology to understand changes in human environmental niches - the habitats humans can use and thrive in - during this time.”
Dr Michela Leonardi at the University of Cambridge and London’s Natural History Museum, the study’s other lead author, said: “Our results showed that the human niche began to expand significantly from 70,000 years ago, and that this expansion was driven by humans increasing their use of diverse habitat types, from forests to arid deserts.”
Many explanations for the uniquely successful dispersal out of Africa have previously been made, from technological innovations, to immunities granted by interbreeding with Eurasian hominins. But there is no evidence of technological innovation, and previous interbreeding does not appear to have helped the long-term success of previous attempts to spread out of Africa.
“Unlike previous humans dispersing out of Africa, those human groups moving into Eurasia after around 60-50,000 years ago were equipped with a distinctive ecological flexibility as a result of coping with climatically challenging habitats,” said Scerri. “This likely provided a key mechanism for the adaptive success of our species beyond their African homeland.”
Previous human dispersals out of Africa - which were not successful in the long term - seem to have happened during particularly favourable windows of increased rainfall in the Saharo-Arabian desert belt, which created ‘green corridors’ for people to move into Eurasia.
The environmental flexibility developed in Africa from around 70,000 years ago ultimately resulted in modern humans’ unique ability to adapt and thrive in diverse environments, and to cope with varying environmental conditions throughout life.
This research was supported by funding from the Max Planck Society, European Research Council and Leverhulme Trust.

Before the ‘Out of Africa’ migration that led our ancestors into Eurasia and beyond, human populations learned to adapt to new and challenging habitats including African forests and deserts, which was key to the long-term success of our species’ dispersal.

Cambridge researchers awarded Advanced Grants from the European Research Council
The successful Cambridge grantees’ work covers a range of research areas, including the development of next-generation semiconductors, new methods to identify dyslexia in young children, how diseases spread between humans and animals, and the early changes that happen in cells before breast cancer develops, with the goal of finding ways to stop the disease before it starts.
The funding, worth €721 million in total, will go to 281 leading researchers across Europe. The Advanced Grant competition is one of the most prestigious and competitive funding schemes in the EU and associated countries, including the UK. It gives senior researchers the opportunity to pursue ambitious, curiosity-driven projects that could lead to major scientific breakthroughs. Advanced Grants may be awarded up to € 2.5 million for a period of five years. The grants are part of the EU’s Horizon Europe programme. The UK agreed a deal to associate to Horizon Europe in September 2023.
This competition attracted 2,534 proposals, which were reviewed by panels of internationally renowned researchers. Over 11% of proposals were selected for funding. Estimates show that the grants will create approximately 2,700 jobs in the teams of new grantees. The new grantees will be based at universities and research centres in 23 EU Member States and associated countries, notably in the UK (56 grants), Germany (35), Italy (25), the Netherlands (24), and France (23).
“Many congratulations to our Cambridge colleagues on these prestigious ERC funding awards,” said Professor Sir John Aston, Cambridge’s Pro-Vice-Chancellor for Research. “This type of long-term funding is invaluable, allowing senior researchers the time and space to develop potential solutions for some of biggest challenges we face. We are so fortunate at Cambridge to have so many world-leading researchers across a range of disciplines, and I look forward to seeing the outcomes of their work.”
The Cambridge recipients of 2025 Advanced Grants are:

“These ERC grants are our commitment to making Europe the world’s hub for excellent research,” said Ekaterina Zaharieva, European Commissioner for Startups, Research, and Innovation. “By supporting projects that have the potential to redefine whole fields, we are not just investing in science but in the future prosperity and resilience of our continent. In the next competition rounds, scientists moving to Europe will receive even greater support in setting up their labs and research teams here. This is part of our “Choose Europe for Science” initiative, designed to attract and retain the world’s top scientists.”
“Much of this pioneering research will contribute to solving some of the most pressing challenges we face - social, economic and environmental,” said Professor Maria Leptin, President of the European Research Council. “Yet again, many scientists - around 260 - with ground-breaking ideas were rated as excellent, but remained unfunded due to a lack of funds at the ERC. We hope that more funding will be available in the future to support even more creative researchers in pursuing their scientific curiosity.”
Eleven senior researchers at the University of Cambridge have been awarded Advanced Grants from the European Research Council – the highest number of grants awarded to any institution in this latest funding round.
