Students at the University of Staffordshire have said they feel “robbed of knowledge and enjoyment” after a course they hoped would launch their digital careers turned out to be taught in large part by AI.

James and Owen were among 41 students who took a coding module at Staffordshire last year, hoping to change careers through a government-funded apprenticeship programme designed to help them become cybersecurity experts or software engineers.

How generative AI in Arc Raiders started a scrap over the gaming industry’s future

The use of AI in the surprise game-of-the-year contender has sparked a heated cultural and ethical debate, and raised existential questions for artists, writers and voice actors

• Don’t get Pushing Buttons delivered to your inbox? Sign up here

Arc Raiders is, by all accounts, a late game-of-the-year contender. Dropped into a multiplayer world overrun with hostile drones and military robots, every human player is at the mercy of the machines – and each other. Can you trust the other raider you’ve spotted on your way back to humanity’s safe haven underground, or will they shoot you and take everything you’ve just scavenged? Perhaps surprisingly, humanity is (mostly) choosing to band together, according to most people I’ve talked to about this game.

In a review for Gamespot, Mark Delaney paints a beguiling picture of Arc Raiders’s potential for generating war stories, and highlights its surprisingly hopeful tone as the thing that elevates it above similar multiplayer extraction shooters: “We can all kill each other in Arc Raiders. The fact that most of us are choosing instead to lend a helping hand, if not a sign that humanity will be all right in the real world, at the very least makes for one of the best multiplayer games I’ve ever played.”

Nvidia earnings: Wall Street sighs with relief after AI wave doesn’t crash

Amid a blackout of data due to the government shutdown, the $5tn chipmaker’s report took on wider significance

Markets expectations around Wednesday’s quarterly earnings report by the most valuable publicly traded company in the world had risen to a fever pitch. Anxiety over billions in investment in artificial intelligence pervaded, in part because the US has been starved of reliable economic data by the recent government shutdown.

Investors hoped that both questions would be in part answered by Nvidia’s earnings and by a jobs report due on Thursday morning.

Neanderthals and early humans ‘likely to have kissed’, say scientists

Study from University of Oxford looks into evolutionary origins of kissing and its role in relations between species

From Galápagos albatrosses to polar bears, chimpanzees to orangutans, certain species appear to kiss. Now researchers suggest Neanderthals did it too – and might even have locked lips with modern humans.

It is not the first time scientists have suggested Neanderthals and early modern humans were intimately acquainted. Among previous studies, researchers have found humans and their thick-browed cousins shared the same mouth microbe for hundreds of thousands of years after the two species split, suggesting they swapped saliva.

Plantwatch: The plant that shoots toxic liquid – and the insects trying to beat it

The bursera plant’s leaves can squirt chemicals 1.5 metres, but over millions of years, some beetles have learned to disarm it

Insects get a nasty surprise if they try biting into the leaves of bursera shrubs and trees: they use a sort of squirt gun to shoot a high-pressure stream of liquid resin at the attacking insect. This liquid is thoroughly repellent and poisonous, but for good measure the resins in the liquid can turn solid when exposed to air and seal a small insect in a tomb.

The squirt gun stores its chemicals in a network of canals in the leaf. When an insect bites a leaf canal, the liquid squirts out as far as 1.5 metres, drenching a small insect in deadly secretions. Larger insects that survive the attack suffer reduced growth and life expectancy.

Nasa releases close-up pictures of comet flying by from another star system

The interstellar visitor, known as 3I/Atlas, will be seen just in this instance, never to come back again

Nasa released close-up pictures on Wednesday of the interstellar comet that’s making a quick one-and-done tour of the solar system.

Discovered over the summer, the comet known as 3I/Atlas is only the third confirmed object to visit our corner of the cosmos from another star. It zipped harmlessly past Mars last month.

Pinprick blood test could detect disease 10 years before symptoms appear, study finds

Molecular profiles will give detailed snapshot of person’s physiology and predict diseases from diabetes to cancer and dementia

The world’s largest study into key substances in the bloodstream has paved the way for a swathe of pinprick tests that can detect early signs of disease more than a decade before symptoms appear, researchers say.

Work on the tests follows the completion of a project by UK Biobank to measure the levels of nearly 250 different proteins, sugars, fats and other compounds in blood collected from half a million volunteers.

Electroconvulsive therapy may have more adverse effects than thought

Study calls for depression treatment to be suspended for more research after reports of heart problems and emotional blunting

Electroconvulsive therapy could be causing a wider range of adverse effects when used to treat depression than previously understood, according to a paper that calls for the practice to be suspended pending more robust research.

Although short- and long-term memory loss is widely known to result from ECT, the research identified 25 further concerning side effects, which included cardiovascular problems, fatigue and emotional blunting.

Christie’s withdraws rare ‘first calculator’ from auction after French court halts export

Move comes after French scientists issued urgent appeal to prevent La Pascaline from leaving the country

A rare example of the first functioning calculating machine in history looks likely to stay in France after Christie’s withdrew it from auction pending a definitive ruling from a Paris court on whether or not it can be exported.

La Pascaline, developed by the French mathematician and inventor Blaise Pascal in 1642, when he was just 19, and billed as “the most important scientific instrument ever offered at auction”, had been expected to fetch more than €2m (£1.8m).

‘Chunks of earth just disappear’: life on a collapsing island – podcast

As the Cop30 climate talks continue in Brazil, Madeleine Finlay hears about a landscape at the opposite end of the planet facing the direct impacts of the climate crisis. The Guardian reporter Leyland Cecco recounts a recent trip to Qikiqtaruk (also known as Herschel Island) off the coast of Canada’s Yukon territory, where he saw first hand how indigenous groups and scientists are reckoning with an ecosystem collapsing into the sea. He tells Madeleine about efforts to preserve the history of the island and how scientists are racing to understand what it means for the fate of other arctic communities.
