Microsoft says its Aurora AI can accurately predict air quality, typhoons, and more
One of Microsoft's latest AI models can accurately predict air quality, hurricanes, typhoons, and other weather-related phenomena, the company claims.
In a paper published in the journal Nature and an accompanying blog post this week, Microsoft detailed Aurora, which the tech giant says can forecast atmospheric events with greater precision and speed than traditional meteorological approaches. Aurora, which has been trained on more than a million hours of data from satellites, radar and weather stations, simulations, and forecasts, can be fine-tuned with additional data to make predictions for particular weather events.
AI weather models are nothing new. Google DeepMind has released a handful over the past several years, including WeatherNext, which the lab claims beats some of the world's best forecasting systems. Microsoft is positioning Aurora as one of the field's top performers — and a potential boon for labs studying weather science.
In experiments, Aurora predicted Typhoon Doksuri's landfall in the Philippines four days in advance of the actual event, beating some expert predictions, Microsoft says. The model also bested the National Hurricane Center in forecasting five-day tropical cyclone tracks for the 2022-2023 season, and successfully predicted the 2022 Iraq sandstorm.
While Aurora required substantial computing infrastructure to train, Microsoft says the model is highly efficient to run. It generates forecasts in seconds compared to the hours traditional systems take using supercomputer hardware.
Microsoft, which has made the source code and model weights publicly available, says that it's incorporating Aurora's AI modeling into its MSN Weather app via a specialized version of the model that produces hourly forecasts, including for clouds.

Meet the tiny Australian Moth that travels 1,000 km and navigates using the stars
An Australian moth follows the stars during its yearly migration, using the night sky as a guiding compass, according to a new study. When temperatures heat up, nocturnal Bogong moths fly about 1,000 kilometres to cool down in caves by the Australian Alps. They later return home to breed and die. Birds routinely navigate by starlight, but the moths are the first known invertebrates, or creatures without a backbone, to find their way across such long distances using the stars. Scientists have long wondered how the moths travel to a place they've never been. A previous study hinted that Earth's magnetic field might help steer them in the right direction, along with some kind of visual landmark as a guide. Related Does cutting off rhinos' horns protect them from poachers? New study supports controversial approach Since stars appear in predictable patterns each night, scientists suspected they might help lead the way. They placed moths in a flight simulator that mimicked the night sky above them and blocked out the Earth's magnetic field, noting where they flew. Then they scrambled the stars and saw how the moths reacted. When the stars were as they should be, the moths flapped in the right direction. But when the stars were in random places, the moths were disoriented. Their brain cells also got excited in response to specific orientations of the night sky. The findings were published Wednesday in the journal Nature. It 'was a very clean, impressive demonstration that the moths really are using a view of the night sky to guide their movements,' said Kenneth Lohmann, who studies animal navigation at the University of North Carolina at Chapel Hill and was not involved with the new research. Researchers don't know what features of the night sky the moths use to find their way. It could be a stripe of light from the Milky Way, a colourful nebula or something else entirely. Whatever it is, the insects seem to rely on that, along with Earth's magnetic field, to make their journey. Related Rare snail that can 'slurp up earthworms like noodles' caught on camera laying an egg from its neck Scientists use special 'squeezing' and electrical probes to collect sperm from endangered kākāpō Other animals harness the stars as a guide. Birds take celestial cues as they soar through the skies, and dung beetles roll their remains short distances while using the Milky Way to stay on course. It's an impressive feat for Bogong moths, whose brains are smaller than a grain of rice, to rely on the night sky for their odyssey, said study author David Dreyer with Lund University in Sweden. 'It's remarkable that an animal with such a tiny brain can actually do this,' Dreyer said.

Microsoft Confirms Windows 11 Automatic Deletions: Take Action Now To Protect Yourself
Microsoft's Windows 11 creates System Restore points, that is, snapshots of your PC's system files, settings and registry. But those points expire and are automatically deleted after 60 days, Microsoft has now confirmed. Users can protect themselves by creating regular System Restore points. 'With System Restore you can revert your PC's state to a previous point in time. By using System Restore, you can undo these changes without affecting your personal files,' Microsoft says. Windows 11 Which is great, but those restore points don't last forever, so it's important to know exactly how long they are there for. Previous documentation suggested that on Windows 10, restore points could last as long as 90 days. Windows Latest reports that 'After Windows 11's release in 2021, the retention period has been anywhere between 10 and 90 days (mostly 10 days),' it says. Ten days really isn't long, but there's good news. In a new support document relating to the June 10 update, Microsoft is a bit more specific. 'After installing the June 2025 Windows security update, Windows 11, version 24H2 will retain system restore points for up to 60 days. To apply a restore point, select Open System Restore. Restore points older than 60 days are not available. This 60-day limit will also apply to future versions of Windows 11, version 24H2,' it says. In other words, Microsoft has confirmed that Windows 11 System Restore points will be deleted after 60 days, so you need to periodically create restore points. That's not as good as 90 days, obviously, but way better than 10 days. 'This will give you multiple snapshots, but Windows will still delete the oldest ones once they exceed the retention window (now 60 days on Windows 11 24H2 by default),' says Windows Latest. To create your own System Restore point, as Windows Latest explains, you open Start and search for 'Create a restore point,' which will open System Protection tab in System Properties. Next, under Protection Settings, check that one of the partitions where you're going to put the backup is protected. Choose that partition and Configure to turn on protection. Then, click Create and follow the onscreen instructions. This will last for 60 days. Now that the deletion date is clear, it seems like creating one every few weeks is good practice.

Wild Things: Birds enjoy an insect boom
Wild Things columnist Eric Brown is buzzing with enthusiasm about the varied insects to be found during a record sunny spring and the benefits to birds relying on them for food. While it awaits a verdict on its future, Crossness Nature Reserve has come alive with a little sunshine particularly encouraging insects out into the open. Lesser emperor dragonflies are being regularly reported by observers at the Belvedere-based reserve under threat from industrial development. Wild Things: Good news for puffins Plenty of common butterflies like holly blue are around, too, plus three marbled whites seen in the Sea Wall Field area. The beautiful ruby-tailed wasp also seen on the reserve is a solitary cuckoo wasp with a dubious habitat of laying its eggs in the nests of other solitary wasp and bee species, particularly mason bees. When the eggs hatch the larvae eat the larvae of the host species in order to develop. Bird interest includes sedge warblers making use of the plentiful reeds with one observed feeding a fledgling. A slow worm was also discovered as Bexley Borough's top reserve maintains its reputation for biodiversity. Insects are busy at Chislehurst Common, too. A gaudy hoverfly known as xanthgogramma pedissequum showed up . It has no official common English name, but it is easy to see from the picture why it is known as 'superb dayglower' across Europe. Also around are speckled wood butterflies and orange-tailed mining bees, andrena haemorrhoa, with their brilliant orange thoraxes. Wild Things: Searching for butterfly royalty Mining bees are solitary bees. They do not form colonies, but live independently, tunnelling into the ground where they make a nest. The glade at the common, with areas of bare earth, is an ideal site. They collect pollen for young to feed on, and are important pollinators. Broad-bodied chaser dragonflies and hairy shieldbugs are among many other insect species to be found on Chislehurst Common. If you are nearby, why not make time for a walk around to see how many insect and bird species you can find ? From my house I have seen many large flying insects. This is good news for the local swifts I first spotted returning from Africa on May 1, six days earlier than my first "house" sighting of 2024. I've even seen one catching an insect and passing it to another swift on the wing. My largest swift count so far at one time has been five and I was delighted to also spot a group of five house martins in the same airspace. Previously I've been lucky to see just a couple of house martins all summer. On one memorable day I saw swifts, house martins and a swallow all pass my window. Maybe an increase in insects has been responsible for luring these birds in the sunniest spring on record. Certainly I expect to hear soon of an increase in butterfly numbers after last year's dismally wet spring hit their numbers.
