A tiny grain from asteroid Ryugu has revealed djerfisherite, a mineral that normally forms in scorching, oxygen-poor settings—conditions Ryugu was never thought to experience.
The surprise find hints that the asteroid either endured unexpected heat spikes or captured exotic material transported across the early Solar System. Microscopy and chemical clues now challenge the idea that Ryugu is compositionally uniform and point to a far more chaotic mixing of planetary building blocks. Scientists are turning to isotopic “fingerprints” to trace the grain’s true origin and decode how primitive asteroids really formed.

Clocks might be far more fundamental to physics than we ever realized.
A new theory suggests what we see around us – from the smallest of quantum actions to the cosmic crawl of entire galaxies – could all be literally a matter of time. Three dimensions of time, in fact.
The basic idea of 3D time isn’t new. But University of Alaska geophysicist Gunther Kletetschka says his mathematical framework is the first to reproduce known properties of the Universe, making it a somewhat serious contender for uniting physics under one consistent model.

The Canadian government has ordered Hikvision’s subsidiary in the country to cease all operations following a review that determined them to pose a national security risk.
The order was forwarded to Hikvision last Friday, and the matter was made public over the weekend by Mélanie Joly, Canada’s Minister of Innovation, Science and Industry.
“Following a National Security Review under the Investment Canada Act, the Government of Canada has ordered Hikvision Canada Inc. to cease all operations in Canada and close its Canadian business,” reads the announcement.
Microsoft has confirmed a new known issue causing delivery delays for June 2025 Windows security updates due to an incorrect metadata timestamp.
As Redmond explains in recent advisory updates, this bug affects Windows 10 and Windows 11 systems in environments with quality update deferral policies that enable admins to delay update installation on managed devices.
While update deployment delays are an expected result when using such policies, the wrong timestamp for the June security updates will postpone them beyond the period specified by administrators, potentially exposing unpatched systems to attacks.
