Ministry of Defence officials have privately accused a UK police force of wrongly handing over the investigation of an American fighter pilot who strangled a British woman to the US military, according to documents obtained by the Guardian.

Adult excavated in an Iraqi Kurdistan cave died more than 70,000 years ago and bears ‘kill shot’ shoulder wound

A smooth round hole in the shoulder blade of a Neanderthal who died more than 70,000 years ago may be the oldest evidence so far of a human ancestor being killed by a wooden spear.

Archaeologists spotted the distinctive injury after excavating skeletal remains of the adult and other Neanderthals from under nearly 8 metres of rock and sediment in the Shanidar cave in Iraqi Kurdistan.

Letter from more than 40 signatories says university has backed away from promised thorough review of events before death

Senior Cambridge academics have criticised the university’s plans to investigate Prof Jason Arday’s death as inadequate, and said those responsible for “serious failures of leadership” should face consequences.

In a letter to Chris Smith, Cambridge’s chancellor, the academics said “it is not yet clear” how the proposed review will answer difficult questions about the university’s involvement in the events leading up to Arday’s death, including its handling of the criticism Arday suffered after his appointment as professor of sociology of education in 2023.

Cambridge previously paid £5,000 compensation after an investigation partially upheld allegations against Dr James Orr

A former student of James Orr who was found to have been bullied by the suspended senior Reform UK figure is reopening a case against the University of Cambridge, after apparent discrepancies emerged over the university’s handling of the incident.

The University of Cambridge has asked Nazir Afzal, a former chief crown prosecutor for north-west England, to lead the first part of its review into the death of the scholar Jason Arday.

Allegations Nathan Cofnas was unqualified for Ghent role and would cause ‘negative impact’ made to senior leaders months ago

Nathan Cofnas, the academic who accused Jason Arday of plagiarism, has been accused of having “very limited expertise” for his academic role by professors also working at Ghent University, who say he has a “far-right agenda”.

Cofnas secured a postdoctoral research role “on the future of liberalism” at Belgium’s Ghent University in March. Weeks later, Ghent’s department of philosophy and moral sciences handed a 19-page statement to university officials, setting out why it believed it was “improbable” that Cofnas was the best candidate.

Recycling system in Cambridgeshire that could save thousands of litres a day is deemed not in line with rules

The largest water reuse system in the UK, which could save thousands of litres of water a day for people living in one of the driest regions of the country, is not allowed to be switched on because of drinking water regulations.

As water supplies in England reach critical levels, the Guardian can reveal that a model water recycling system within an urban housing development in Cambridgeshire has not been switched on since it was made ready in 2021.

Amid the grief and rage at a tragic loss, it’s right to differentiate between those who fought a culture war and others who just sought the truth

Even now it is very difficult to process the scale of tragedy that engulfed Jason Arday and those who loved him. The unbearable sadness at his death; the wretched knowledge that the very public onslaught against him began with the malign machinations of a self-defined “race realist” – who believes that, in an ideal world, black people would “disappear from almost all high-profile positions outside of sports and entertainment”. The horror that a rightwing and far-right campaign seeking a victim to fuel its nativist prejudices can now crow that it found one.

There is wide and profound grief and of course there is rage, focused and unfocused. Both were on display as thousands joined a protest vigil in Trafalgar Square on Monday evening.

Cambridge University’s leadership has bowed to internal pressure for an independent investigation into its appointment of Jason Arday as a professor, with its vice-chancellor admitting the affair has damaged the institution.

Prof Deborah Prentice said she recognised the “anger and anxiety around this damaging and difficult case” but described it as an aberration that should not be used to cast aspersions on the abilities of its staff of colour.

Fellow pupils at his primary school have challenged Cambridge academic’s story, though others support it

The story of Jason Arday’s extraordinary rise to becoming the youngest black professor in the history of the University of Cambridge is all the more remarkable for one claim: that he did not learn to speak until just shy of his 12th birthday.

This claim was mentioned in a letter announcing his resignation last week, which came amid mounting questions about his academic work and statements he had made about his past.

Organoids and tissues grown from human cells promise more accurate results, with £20m Cambridge project to create standardised models

Miniature human organs and other tissues are to be grown from NHS patients’ cells in a drive to improve medicine testing and reduce the number of animals used in drug development.
