A curated list of other prominent stories from this day.
NASA’s Roman Space Telescope has demonstrated pointing stability precise enough to hold a target as if aiming a laser at a dime from roughly 150 miles away. Its coronagraph also produced focused images of stars in the Large Magellanic Cloud, marking an important test of the instrument’s ability to block starlight and study faint objects nearby.

Magnetic fossils dating back 97 million years may be the oldest evidence of an animal using Earth’s magnetic field for navigation. Their complex structure suggests an unknown ocean creature could have traveled thousands of kilometers with unusual precision.
7:54 AMScienceDaily
JWST observations show that galaxies were releasing carbon, oxygen, and other heavy elements into space only about 500 million years after the Big Bang. The finding indicates that chemical enrichment began earlier than expected and may have obscured evidence of the universe’s first stars.
7:24 AMScienceDaily
Ultrashort electrical pulses pushed superconductors close to the point where their electron pairs break apart. The technique exposed differences in how various superconducting materials approach this limit and offers a new way to investigate their nonequilibrium quantum behavior.

Swiss glaciers have lost a severe share of their ice in just five years, accelerating the retreat of the country's alpine ice fields. The loss threatens landscapes, water systems and the alpine economy.

NASA’s Roman Space Telescope has demonstrated pointing stability precise enough to hold a target as if aiming a laser at a dime from roughly 150 miles away. Its coronagraph also produced focused images of stars in the Large Magellanic Cloud, marking an important test of the instrument’s ability to block starlight and study faint objects nearby.
Roman has now cleared two critical technical hurdles for direct exoplanet imaging: stable pointing and

Reliable starlight suppression is the condition that determines whether Roman can turn exoplanet imaging from a concept into routine observation.
Summary
Magnetic fossils dating back 97 million years may be the oldest evidence of an animal using Earth’s magnetic field for navigation. Their complex structure suggests an unknown ocean creature could have traveled thousands of kilometers with unusual precision.
The fossils push evidence of sophisticated animal magnetoreception deep into the Cretaceous, showing that long-distance

The finding could rewrite the timeline for the evolution of magnetic sensing and long-distance animal migration.
Summary
JWST observations show that galaxies were releasing carbon, oxygen, and other heavy elements into space only about 500 million years after the Big Bang. The finding indicates that chemical enrichment began earlier than expected and may have obscured evidence of the universe’s first stars.
The early appearance of heavy elements compresses the timeline for star formation, stellar death, and

Early enrichment changes the baseline for interpreting JWST’s oldest galaxies and reconstructing the universe’s first generation of stars.
Summary
Ultrashort electrical pulses pushed superconductors close to the point where their electron pairs break apart. The technique exposed differences in how various superconducting materials approach this limit and offers a new way to investigate their nonequilibrium quantum behavior.
The experiment probes superconductivity at its failure threshold, where the mechanisms that stabilize electron pairing

Seeing how superconductivity collapses could guide faster, more controlled quantum electronics and improve models of material performance.
Summary
Swiss glaciers have lost a severe share of their ice in just five years, accelerating the retreat of the country's alpine ice fields. The loss threatens landscapes, water systems and the alpine economy.
The decisive shift is the speed of the melt, which is outpacing the gradual decline
