A historical dream team of five master sculptors, including Michelangelo, Rodin and Takamura, have trained artificial intelligence (AI) to design a sculpture dubbed "the Impossible Statue", now on show in a Swedish museum.

"This is a true statue created by five different masters that would never have been able to collaborate in real life," said Pauliina Lunde, a spokeswoman for Swedish machine engineering group Sandvik that used three AI software programmes to create the artwork.

Claims the US government has secretly retrieved crashed alien spacecraft and their non-human occupants are hardly new. They are firmly entrenched in post-war American UFO lore and conspiracy theory, inspiring the most famous narrative in ufology: the “Roswell incident”.

Now, however, journalists Leslie Kean and Ralph Blumenthal have injected fresh vigor into these aging claims – apparently with the Pentagon’s approval.

The first evidence of a virgin birth in crocodiles has been reported in a captive American crocodile, Crocodylus acutus, who was housed on her own for 16 years in a zoo in Costa Rica. She laid a clutch of 14 eggs, of which seven seemed viable and were artificially incubated. The eggs failed to hatch and the contents of six of them were indiscernible. But one contained a fully formed foetus, genetically identical to its mother, showing no evidence of input from any males.

This isn’t the first case of a virgin birth in the animal kingdom. Baby lizards, snakes, sharks and birds, including the California condor, have all been documented hatching from unfertilized eggs.

Record-high greenhouse gas emissions and diminishing air pollution have caused an unparalleled acceleration in global warming, 50 top scientists warned Thursday in a sweeping climate science update.

From 2013 to 2022, "human-induced warming has been increasing at an unprecedented rate of over 0.2 degrees Celsius per decade," they reported in a peer-reviewed study aimed at policymakers.

One of the world's most active volcanoes has erupted again, with lava spewing from Kilauea in Hawaii on Wednesday.

Footage showed fissures have opened up at the base of a crater on the volcano, which regularly springs to life, with vulcanologists calling the eruption "dynamic."

Staying in touch with a loved one after their death is the promise of several start-ups using the powers artificial intelligence, though not without raising ethical questions.

Ryu Sun-yun sits in front of a microphone and a giant screen, where her husband, who died a few months earlier, appears.

Sea temperatures at a depth of about 10 metres were a quarter of a degree Celsius higher than ice-free oceans in May averaged across 1991 to 2020, according to the Copernicus Climate Change Service (C3S).

Year-round, long-term trends have added 0.6C to the ocean's surface waters in 40 years, said C3S deputy director Samantha Burgess, noting that April had also seen a new record for heat.

Artificial intelligence has proven itself useful in reading medical imaging and even shown it can pass doctors' licensing exams.

Now, a new AI tool has demonstrated the ability to read physicians' notes and accurately anticipate patients' risk of death, readmission to hospital, and other outcomes important to their care.
