Researchers have developed an AI-designed vaccine that could protect against a broad range of coronaviruses, including future strains that have not yet emerged.
Scientists at the University of Cambridge say the project marks the first time an Artificial Intelligence-designed vaccine antigen has been tested in human volunteers. They believe the technology could eventually help protect against entire families of viruses rather than individual strains.
AI designs a vaccine for multiple coronavirus threats
Most vaccines are built using versions of viruses that are already circulating. As those viruses mutate, vaccines often need updating to remain effective. The new approach aims to overcome that challenge.
Researchers collected genetic information from a wide range of coronaviruses identified through surveillance programs that monitor viruses with pandemic potential. Artificial intelligence then analyzed the data and designed a “super-antigen,” a vaccine component intended to train the immune system to recognize many related coronaviruses at once.
Antigens are the parts of vaccines that teach the immune system what to attack. Researchers say the AI-designed antigen could potentially protect against current coronavirus variants as well as animal viruses that may one day spread to humans.
Professor Jonathan Heeney of the University of Cambridge described the research as a major shift in pandemic preparedness. He said the goal is to develop vaccines that protect against future threats rather than reacting after outbreaks occur.
Early human trials show encouraging results
The first human trial involved 39 volunteers and was designed to evaluate safety. Researchers reported no major safety concerns. A larger study involving about 200 participants is now underway to better understand how effectively the vaccine stimulates immune responses.

Results published in the Journal of Infection showed that the vaccine generated a measurable, though modest, immune response. Despite the early-stage findings, researchers and independent experts say the technology shows significant promise.
Professor Saul Faust of the University of Southampton, who helped conduct some of the trials, said the approach has strong potential, particularly for rapidly changing viruses that can spark future pandemics.
Researchers expand the technology to other diseases
Researchers are already applying the technology to other diseases. Animal studies are underway on a universal influenza vaccine that could eliminate the need for yearly updates. Scientists are also developing vaccines targeting H5N1 bird flu and viral hemorrhagic fevers, including Ebola.
Professor Andy Pollard, director of the Oxford Vaccine Group, said the findings add to growing evidence that artificial intelligence could transform vaccine research. He noted that future AI systems may help predict how the immune system will respond to vaccine candidates, potentially accelerating development.
Experts see a new era for vaccine development
Professor Marian Knight, scientific director at the National Institute for Health and Care Research, called the trial an important step toward broader and longer-lasting protection against viral diseases.
UK Science Minister Patrick Vallance said the early results demonstrate how artificial intelligence and scientific research can work together to create new medical tools.
Researchers caution that much larger studies are needed before the vaccine can be widely used. However, they believe the technology could help the world prepare for future pandemics before they begin.

More than 5,300 years after his death, Ötzi the Iceman is helping scientists uncover a hidden world of cold-adapted yeasts. Researchers have discovered that the famous mummy’s skin and stomach contain yeasts that likely colonized his body shortly after his death. Some of these microorganisms may still be active today, according to a study published June 3 in the journal Microbiome.
Ötzi, one of the world’s best-preserved natural mummies, was discovered by hikers in the Ötztal Alps in 1991. Scientists believe he died around 3300 B.C. after a violent attack.
Microorganisms survived alongside the mummy
Researchers analyzed swab samples, thawed water from inside the mummy, soil from the discovery site, and material from Ötzi’s storage environment. Using genetic analysis, they identified microbial communities living on and around the remains.
The study found that many of the yeasts are closely linked to cold Alpine environments. Scientists believe they originated from the glacier where Ötzi’s body remained frozen for thousands of years.
The findings suggest the microorganisms survived after the mummy was recovered and transferred to a refrigeration chamber maintained at about 21 degrees Fahrenheit (minus 6 degrees Celsius).
More than 5,300 years after his death, Ötzi the Iceman is still surprising scientists.

Researchers found that the yeasts are highly adapted to cold conditions, allowing them to persist in both glacial environments and modern storage facilities.
Ancient yeasts may still be active
The team successfully cultivated four cold-adapted yeast species from samples collected from Ötzi’s skin and from water taken from inside the mummy.
Genetic evidence showed signs of ancient DNA damage, suggesting the yeasts either remained dormant for more than five millennia or descended directly from the original microorganisms that colonized the body after death.
Researchers also compared skin samples collected in 2019 with samples gathered in 2010. The analysis showed that a cold-loving yeast known as Glaciozyma had become the dominant strain over time.
The finding indicates that the glacier-associated yeast has continued to slowly grow while the mummy has remained in cold storage.
Study co-author Frank Maixner of the Eurac Research Institute for Mummy Studies said the discovery shows that Ötzi is not simply a preserved archaeological artifact but part of an evolving biological system.
Potential uses beyond archaeology
The researchers also explored whether the ancient yeasts could have practical applications. Preliminary tests showed some strains performed well in sourdough fermentation. Lead author Mohamed Sarhan said the results suggest the yeasts could potentially be used in industries that rely on fermentation, including bread and beer production.
Scientists also identified modern microorganisms that were likely introduced during decades of conservation and study. It remains unclear whether these microbes affect the long-term preservation of the mummy.
Researchers said Ötzi offers a rare glimpse into ancient microbial life. However, they cautioned that the mummy represents only one individual and cannot fully reflect the broader population of the Copper Age.
Interest in unidentified objects in the sky often emerges during periods of uncertainty, when people seek explanations for phenomena that appear mysterious or difficult to understand.
The human mind tends to interpret unusual sights as warnings, threats, or messages from beyond the familiar world, especially during times of social tension. Efforts to understand such phenomena have often evolved into large-scale government programs where scientific investigation served purposes that extended beyond pure research.
How the Flying Saucer Phenomenon Began
The story gained momentum when experienced pilot Kenneth Arnold reported seeing a group of unusual objects flying over mountain peaks. Instruments estimated their speed at approximately 1,900 kilometers per hour — an extraordinary figure for the technology of that era.

For decades, conventional wisdom held that bread didn’t exist among Paleolithic people and was a relatively recent human innovation, an agricultural byproduct that emerged with the rise of farming in the Neolithic era, roughly 10,000 years ago. Recent archaeological discoveries have radically challenged this view, however, pushing the timeline of breadmaking back by at least 20,000 years.
In what can only be described as a groundbreaking study, a team of Italian researchers has revealed that Paleolithic hunter-gatherers in Europe not only consumed wild plants but also processed them into flour and baked a primitive flatbread. These findings were published in the prestigious journal Proceedings of the National Academy of Sciences (PNAS). They suggest that the roots of culinary innovation run far deeper than previously imagined.
Grinding stones and starch residue
At the heart of this discovery are ancient grinding stones. The archaeologists unearthed these flat stone slabs and pestle-like tools at sites across Italy, Russia, and the Czech Republic. The tools, dated to around 30,000 years ago, were originally assumed to have been used for processing pigments or crushing seeds. Nevertheless, when researchers Anna Revedin and Laura Longo of the Italian Institute of Prehistory and Early History in Florence conducted a detailed microscopic analysis, they uncovered traces of starch granules embedded in the stone surfaces.
The starches were identified as those of cattails, ferns, and other starchy wild plants, which would have required careful preparation to be rendered digestible. Revedin’s team concluded that these Paleolithic humans had not only harvested the plants but had dried, ground, and mixed them with water to form a kind of dough. Additionally, they likely cooked the resulting paste on hot stones near the fire, producing an early version of unleavened bread.
Rethinking the Paleolithic diet
The ancient Greeks themselves had a clear grasp of the evolution of human diet. Hippocrates, the father of medicine, wrote in his work On Ancient Medicine:
“It is for this reason, I believe, that people sought out food more suited to human nature, and eventually discovered the kind we now use. From wheat, after soaking, grinding, kneading, sifting, and baking, they made bread; from barley, they made flatcakes. After many efforts, they cooked, baked, mixed, and blended foods, diluting the strong and raw with milder ingredients, shaping everything according to human nature and capacity.”
The implications are profound. Until now, the standard narrative of Paleolithic diets emphasized a reliance on animal protein. This included meat and fish, with foraged fruits and plants playing only a minor role. The recent discovery challenges that model, however. Moreover, the implication is that these early humans were actually greatly skilled in the complex processing of wild plant foods. In other words, they also possessed the sophisticated ability to cook.
Furthermore, the evidence of flour production long before the advent of agriculture hints at a continuity of knowledge. The leap from gathering and grinding wild plants to cultivating domesticated grains may not have been as abrupt or revolutionary as once believed. Paleolithic peoples were far from passive consumers of raw resources, and the rise of farming could in fact have been the result of millennia of experimentation, habit, and accumulated expertise.

A quiet revolution
Perhaps most striking is what this discovery on bread reveals about Paleolithic ingenuity. The production of flour and bread is not simply a dietary choice. It reflects planning, patience, and an understanding of food chemistry. Drying plant roots, grinding them into powder, and then baking them requires more than survival instinct. It also requires culture.
As more research sheds light on the lives of our Paleolithic ancestors, it becomes increasingly clear that they were not the brutish cave-dwellers of outdated caricatures. They were observant, resourceful, and remarkably sophisticated in their interaction with the natural world.
Bread, it turns out, is not just the food of civilization. It may have been the food of pre-civilization, as well.

A 4,000-year-old child’s skull discovered in Uzbekistan is offering rare evidence of one of the oldest known surgery in Asia, shedding new light on medical knowledge in the Bronze Age.
The remains belonged to a child who died at about 5 years old. Researchers found clear signs of cranial trepanation, a procedure that involved cutting or drilling into the skull. The discovery represents the oldest documented evidence of surgery in Central Asia and one of the oldest known examples anywhere in Asia.
A joint team of Italian and Uzbek researchers uncovered the skeleton during excavations in the Northern Bactria region of southern Uzbekistan, near the border with Afghanistan.
Evidence of a complex procedure
Archaeologists found the child buried in a single grave alongside another child who died at about 3 years old. Examination of the older child’s skull revealed distinct traces of trepanation that researchers believe were made using stone or bone tools.
Trepanation is among the oldest surgical procedures known to humanity. Archaeologists have documented similar operations in ancient societies across Europe, Africa and Asia. The practice may have been used to treat head injuries, epilepsy, severe headaches or other medical conditions. In some cultures, it may also have served ritual or spiritual purposes.

Researchers noted that medicine and religion were often closely connected in ancient societies, making it difficult to determine the exact reason for the operation.
The findings also raise questions about the level of medical expertise that existed in Central Asia thousands of years ago. Performing such a procedure would have required specialized knowledge of the human body and considerable technical skill.
A window into the Oxus civilization
The burial was discovered at the prehistoric settlement of Djarkutan, one of the most important urban centers of the Oxus civilization. Researchers dated the grave to the late third millennium B.C.
Also known as the Bactria-Margiana Archaeological Complex, or BMAC, the Oxus civilization flourished across parts of modern-day Uzbekistan, Turkmenistan and Afghanistan between about 2500 and 1500 B.C. The culture is known for its advanced agriculture, urban development and rich material traditions.
Researchers began a broader project to investigate Djarkutan and other aspects of the Oxus civilization in 2024. “Djarkutan continues to surprise us,” excavation director Enrico Ascalone said in a statement. “A cranial trepanation on a child, four thousand years ago, in Central Asia: until yesterday it was unthinkable. Today it is in our data.”
Questions remain unanswered
The discovery has also created new mysteries. Researchers are now investigating who may have performed the operation, what medical knowledge was available at the time and why such a procedure was carried out on a young child.
Evidence of ancient trepanation is relatively common in some parts of the world, but cases involving children of this age remain rare. Further analysis may help researchers understand whether the operation was intended to treat an illness, respond to an injury or fulfill a ritual purpose.
For now, the skull offers a remarkable glimpse into the medical practices, beliefs and capabilities of a Bronze Age civilization that thrived in Central Asia four millennia ago.
