‘This would have been a wild dream a year ago,” says Andrea Ceccolini, standing on Arctic sea ice just a 4-mile snowmobile ride from the Inuit town of Cambridge Bay, northern Canada. To his left are sky blue ponds of meltwater created in the last few days by a sun that no longer sets in the high north summer. To his right, the sea ice is still a brilliant white, the light dusting of snow on top continuing to sparkle.
“It’s incredibly different, the boundary – I mean, you can point to it,” he says. The difference is the result of a bold geoengineering experiment being conducted by Ceccolini’s company, Real Ice, funded by the UK government.
Five months earlier, the team had braved temperatures of -40C on the sea ice to drill holes and pump 50,000 tonnes of ocean water up on to its surface. It froze almost immediately, thickening the 1.5-metre-deep ice by about 50cm, according to the new measurements.
That has protected the ice, at the start of the melt season at least, and is an early sign that one day, perhaps, it may be possible to refreeze a significant part of the Arctic.
The US military said it killed four more people in a boat strike in the eastern Pacific ocean on Tuesday, marking the third deadly attack on vessels in the region in four days.
The astronauts aboard NASA's Artemis II have now traveled farther from Earth than any other humans in history, breaking the Apollo 13 record.
On February 26, 2025, a NASA probe called Lunar Trailblazer lifted off from Kennedy Space Center in Florida. Its mission was to map the water on the moon. But a day after launch, mission managers lost contact with the spacecraft, and it was never heard from again.

The Nobel physics prize is awarded by the Royal Swedish Academy of Sciences and includes a prize sum totalling 11 million Swedish crowns ($1.2 million) that is shared among the winners if there are several, as is often the case.
Bret Adee is one of the largest beekeepers in the US, with 2 billion bees across 55,000 hives. The business has been in his family since the 1930s, and sends truckloads of bees across the country from South Dakota, pollinating crops such as almonds, onions, watermelons and cucumbers.
