Team now plans to see if they can use yeast strains harvested from Ötzi the Iceman to brew beer too

Scientists have baked a sourdough loaf of bread using yeast strains harvested from a 5,000-year-old mummy and now plan to see if they can use them to brew beer too.

The yeast came from Ötzi the Iceman, a famous corpse remarkably preserved by being frozen in Alpine ice near the Italy-Austria border until he was discovered in 1991. Ötzi has been the subject of intense study since he was found and has shed much light on pre-historic European people and their way of life.

Exclusive: New biography uncovers Frank Hawking’s papers in which he lamented that his son had ‘little initiative’

In exploring the physics and geometry of the universe, Stephen Hawking became a world-renowned pioneer of black hole theory, writing the bestselling book A Brief History of Time, which has sold more than 13m copies, and inspiring people to “look up at the stars and not down at your feet”.

But, during Hawking’s student years and as he approached adulthood, his father was deeply concerned about how his son would turn out. Frank Hawking lamented that “he hangs round the house with little initiative and does not study much”, according to previously unknown diaries that he had written partly in code.

Pandemic report warns of growing global threat as health teams in Africa move to contain Ebola outbreak

The world is becoming less resilient to outbreaks of infectious diseases, experts have warned, as health authorities in the Democratic Republic of the Congo and Uganda scramble to contain an outbreak of Ebola.

The Global Preparedness Monitoring Board (GPMB) said in a report published on Monday that “as infectious disease outbreaks become more frequent they are also becoming more damaging”, warning that pandemic risk is outpacing investments in preparedness and “the world is not yet meaningfully safer”.

‘We’re not ready’: US lags on pandemic preparedness after Covid, experts say

Experts say slashed funding and growing misinformation are some of the greatest challenges facing public health

The hantavirus outbreak, while unlikely to spark the next big pandemic, is shining a spotlight on the ways public health has deteriorated in the US: its ability to test for rare diseases, its expertise on outbreak prevention and response, its ability to battle misinformation and restore trust.

“Assuming everything goes well in containing this outbreak, which I hope it does, the takeaway from that should not be ‘we’re fine,’” said Stephanie Psaki, former White House global health security coordinator. “We’re not ready for this type of threat.”

Powerful radar system is providing new data on city’s subsidence, which experts hope will draw more attention to it

Walking into Mexico City’s sprawling central Zócalo is a dizzying experience. At one end of the plaza, the capital’s cathedral, with its soaring spires, slumps in one direction. An attached church, known as the Metropolitan Sanctuary, tilts in the other. The nearby National Palace also seems off-kilter.

The teetering of many of the capital’s historic buildings is the most visible sign of a phenomenon that has been ongoing for more than a century: Mexico City is sinking at an alarming rate.

Exclusive: Sperm re-transplant offers hope that boys left infertile by chemotherapy could have biological children one day

In a groundbreaking fertility trial, a man whose testicular tissue was frozen before he underwent chemotherapy as a child to be re-transplanted 16 years later has been able to produce sperm.

It is the first time a transplant of cryopreserved prepubertal testicular tissue has been demonstrated to restore sperm production in an adult patient. The 27-year-old man had the sample frozen when he was 10, before undergoing potent chemotherapy as part of treatment for sickle cell disease.

WHO prequalification of Coartem Baby means newborns can be safely treated rather than using medication for older children

The first malaria treatment for babies has been approved by the World Health Organization, opening the door to widespread use around the globe.

In parts of Africa, up to 18% of children under six months will be infected with malaria, but there has historically been no safe treatment for the smallest of them. There were 610,000 deaths from malaria in 2024, about three quarters of which were under-fives in Africa.

Knee surgery for cartilage damage does not benefit patients, study suggests

People with meniscus tears who underwent surgery had poorer knee function and worse osteoarthritis after 10 years than those who did not

A common knee surgery for cartilage damage does not benefit patients and may lead to worse outcomes, a 10-year trial suggests.

The study tracked outcomes for patients treated for a meniscus tear, who were given a partial meniscectomy, one of the most common orthopaedic surgeries. Their trajectories were compared with patients who had randomly been assigned to receive “sham surgery”, in which no procedure was carried out.

NSW and Queensland governments ‘severely underdelivered’ on promised infrastructure to improve water flows, independent review finds

Two state governments have drastically underdelivered more than $160m in infrastructure measures to improve river health in the northern Murray-Darling basin eight years since they were promised, a major independent review has found.

This includes failure by the New South Wales government to secure any of the private land access needed to improve water flows over floodplains in the state’s Gwydir region, where scientists had to scramble to rescue turtles in dried up wetlands last week.

River ecologist says ‘classic bureaucratic tangle’ led to government agency stopping flows to Gwydir wetlands region in March

A leading scientist has criticised an “appalling” New South Wales government agency decision to stop water flowing to wetlands in the state’s north-west, saying it was “absolutely crazy” that researchers had to scramble to save animals buried in drying mud.

Guardian Australia reported on Saturday that turtles, waterbirds, frogs and sheep had died after Water NSW abruptly stopped flows to the Gwydir wetlands region near Moree in March.

Jeremy Hansen praised for speaking French in space after Air Canada chief’s linguistic snub exposed tensions and drew rebuke from PM

Few people foresaw humanity’s quest for the moon as accurately as the 19th-century French author Jules Verne, whose two works –From the Earth to the Moon and Around the Moon – anticipated many of the features of modern lunar exploration.

But Verne’s language had never been spoken in deep space until the Canadian astronaut Jeremy Hansen uttered four words during Nasa’s recent Artemis II mission.
