news Astronomy Evidence status: Official announcement
NASA says Roman Space Telescope's main camera has 63 nm RMS optical error against a 90 nm requirement. The figures are the mission team's own.
explainer Chemistry
Water dissolves salt and sugar because its molecules are polar and form hydrogen bonds, and its dielectric constant is 78.3. Why oil, fat and glass resist it.
news Astronomy Evidence status: Peer reviewed · JWST observations
JWST finds gas near Sagittarius A* holds about 1.8 times the Sun's metals, like nearby stars. Here is how it was measured and what stays uncertain.
news Astronomy Evidence status: Peer reviewed · Modelling of telescope observations
A new A&A study infers Neptune's deep atmosphere holds more oxygen than Uranus's, hinting at different origins. The ranges overlap and rest on mixing models.
news Biology Evidence status: Peer reviewed · Lab aquarium study
In aquarium tests, all 5 bleached coral fragments touching a healthy clone recovered; the 5 held a few millimetres apart did not. A small lab study, not a reef fix.
news Biology Evidence status: Peer reviewed; DNA (phylogenomic) study; fossil literature review
DNA from museum owls suggests barn owls reached the Americas through the Caribbean, which later lost six barn owl species, more than any other island region.
news Biology Evidence status: Peer reviewed · Observational (historical records)
A century of records shows most tracked European bee species and about half of hoverflies now occupy fewer places, though most species still persist.
news Physics Evidence status: Peer reviewed · Collider measurement
STAR at Brookhaven's RHIC finds jets lose energy in oxygen–oxygen collisions, a sign of quark–gluon plasma at low energy. What was measured and its limits.
news Biology Evidence status: Peer reviewed; population biobank analysis; no health outcomes assessed
A survey of about 905,000 genomes finds a typical person carries 4.3 to 5.3 million variants and 1 to 3 rare disease-linked ones, mostly as carriers.
