Chef with 10 Michelin stars has designed meals for Sophie Adenot’s trip to International Space Station next year

When the French astronaut Sophie Adenot travels to the International Space Station (ISS) next year, she will be heading for the stars – not quite in celestial but certainly in gastronomic terms.

Adenot will dine on not just freeze-dried space food staples but also French classics such as lobster bisque, foie gras and onion soup prepared specially for her by a chef with 10 Michelin stars, the European Space Agency (Esa) announced on Wednesday.

Unusual burial of man, thought to have been a potter, in sealed vessel may have helped DNA survive past four millennia

A man whose bones were shaped by a lifetime of hard labour more than 4,500 years ago has become the first ancient Egyptian to have his entire genetic code read and analysed by scientists.

The skeleton of the man, who lived at the dawn of the Age of the Pyramids, was recovered in 1902 from a sealed pottery vessel in a rock-cut tomb in Nuwayrat, 165 miles south of Cairo, and has been held in a museum since.

News comes as research finds record lows of Antarctic sea ice had seen more icebergs splintering off ice shelves

Scientists analysing the cascading impacts of record low levels of Antarctic sea ice fear a loss of critical US government satellite data will make it harder to track the rapid changes taking place at both poles.

Researchers around the globe were told last week the US Department of Defence will stop processing and providing the data, used in studies on the state of Arctic and Antarctic sea ice, at the end of this month.

Study suggests role of male parents may be under-appreciated in some primate species

If male baboons were subject to the same kind of cultural commentary as humans, the phrase “deadbeat dads” might be called for, such is the primate’s relatively limited involvement in raising their young.

But a study suggests that even their little effort might go a long way, with female baboons who experience a stronger relationship with their fathers when young tending to live longer as adults.

Chartered spaceflight for India, Poland and Hungary’s first astronauts in decades delayed indefinitely

A chartered spaceflight for India, Poland and Hungary’s first astronauts in decades has been delayed indefinitely because of leak concerns at the International Space Station.

The National Aeronautics and Space Administration (Nasa) said Thursday that it had postponed the Axiom Mission 4 to the ISS to monitor the cabin pressure on the Russian side of the orbiting lab before accepting visitors. Officials stressed that the seven astronauts currently at the space station are safe and that other operations up there would not be affected.

Peru drops plan to shrink protected area around Nazca Lines archaeological site

Posted on by

Critics had claimed that plan announced in May exposed complex of desert etchings to impact of informal mining

Peru’s government has abandoned a plan that reduced the size of a protected area around the country’s ancient Nazca Lines, after criticism the change made them vulnerable to the impact of informal mining operations.

Peru’s culture ministry said on Sunday that it was reinstating with immediate effect the protected area covering 5,600 square kilometers (2,200 square miles), that in late May had been cut back to 3,200 sq km. The government said at the time the decision was based on studies that had more precisely demarcated areas with “real patrimonial value”.

Psychologist and writer’s appearance on Aporia condemned for helping to normalise ‘dangerous, discredited ideas’

The Harvard psychologist and bestselling author Steven Pinker appeared on the podcast of Aporia, an outlet whose owners advocate for a revival of race science and have spoken of seeking “legitimation by association” by platforming more mainstream figures.

The appearance underlines past incidents in which Pinker has encountered criticism for his association with advocates of so-called “human biodiversity”, which other academics have called a “rebranding” of racial genetic essentialism and scientific racism.

Resilience would have made history as the first non-US commercial lander to make a successful touchdown

An attempt to land a commercially built spacecraft on the surface of the moon looked to have ended in failure on Thursday, two years after its predecessor, launched by the same Japanese company, crashed following an uncontrolled descent.

Resilience, an un-crewed vehicle from the Tokyo company ispace, would have made history as the first non-US commercial lander to make a successful touchdown, scheduled for 3.17pm ET Thursday (4.17am JST Friday) at Mare Frigoris (the Sea of Cold) in the far north of the moon.

Researchers enlisted help of AI along with radiocarbon dating to produce new insights into ancient texts

Many of the Dead Sea scrolls could be older than previously thought, with some biblical texts dating from the time of their original authors, researchers say.

The first of the ancient scrolls were discovered in the caves of Qumran in the Judean desert by Bedouin shepherds in the mid-20th century. The manuscripts range from legal documents to parts of the Hebrew Bible, and are thought to date from around the third century BCE to the second century CE.

World’s oldest fingerprint may be a clue that Neanderthals created art

A man 43,000 years ago dipped a finger in red pigment and made a nose on a face-like pebble in Spain, scientists say

One day around 43,000 years ago, a Neanderthal man in what is now central Spain came across a large granite pebble whose pleasing contours and indentations snagged his eye.

Something in the shape of that quartz-rich stone – perhaps its odd resemblance to an elongated face – may have compelled him to pick it up, study it and, eventually, to dip one of his fingers in red pigment and press it against the pebble’s edge, exactly where the nose on that face would have been.

Case of man carrying rare genetic variant fuels calls for limit on number of children that can be fathered by one donor

The sperm of a man carrying a rare cancer-causing mutation was used to conceive at least 67 children, 10 of whom have since been diagnosed with cancer, in a case that has highlighted concerns about the lack of internationally agreed limits on the use of donor sperm.

Experts have previously warned of the social and psychological risks of sperm from single donors being used to create large numbers of children across different countries. The latest case, involving dozens of children born between 2008 and 2015, raises fresh concerns about the complexity of tracing so many families when a serious medical issue is identified.

Brain tumour diagnosis could be made within hours, say researchers

New testing method means treatments could start sooner, possibly before patient leaves the operating table

A new method for diagnosing brain tumours could cut the time patients wait for treatments by weeks to hours and raise the possibility of novel types of therapy, researchers have said.

According to the Brain Tumour Charity, about 740,000 people around the world are diagnosed with a brain tumour each year, around half of which are non-cancerous. Once a brain tumour is found, a sample is taken during surgery and cells are immediately studied under a microscope by pathologists, who can often identify the type of tumour. However, genetic testing helps to make or confirm the diagnosis.
