news Biology Evidence status: Peer reviewed; modelling study (projections)
Models of 993 cactus species that add severe drought project 25–35% losing over 80% of suitable climate by 2100. What the Nature study shows, and its limits.
news Earth Evidence status: Peer reviewed; measurements of rock samples plus modelling; subduction is an interpretation
Zircons in a 3.95-billion-year-old gneiss from Hebei, China, hint at a mantle depleted in the Hadean and seafloor buried over 50 km deep, perhaps by subduction.

Pet guinea pigs are often said to live 5 to 8 years, but UK vet records put the median age at death at 4 years. The record, wild relatives and…
news Chemistry Evidence status: Peer reviewed · Measurements of volcanic samples
Melt droplets in Kīlauea lavas carry carbon at −1‰ versus −7‰ for normal mantle. A PNAS team reads it as core carbon from outer solar system meteorites.
news Biology Evidence status: Peer reviewed · Observational field study
Microplastics were found in the blood of 43 of 47 wild tapirs and anteaters in Brazil, with higher levels nearer development. The link is an association.
news Astronomy Evidence status: Peer reviewed · Reanalysis of existing public data
A CSIRO AI method trained on everyday photos finds the M87* black hole ring at 42.2 μas, matching the 2019 EHT image. Same data, new analysis: what it shows.

Pet bearded dragons live about 7 to 15 years in RSPCA guidance, and one was verified at 20 years 155 days. What we know, and don't, about wild dragons.
news Astronomy Evidence status: Peer reviewed · Observations of one system
JWST and Gemini North found two quasars about 18,100 light-years apart, 900 million years after the Big Bang. A lensed double image is not yet ruled out.
news Astronomy Evidence status: Peer reviewed · Statistical analysis of a public catalogue
Gravitational-wave data show merging black holes crowd near 10 solar masses and nearly vanish at 12–16. A model links the peak to stars that fail to explode.
