news Biology Evidence status: Peer reviewed; observational study of pet dogs
A Science study of 894 pet dogs links faster DNA-methylation ageing to large size and male sex. What it found, how, and why it doesn't yet prove a cause.
news Biology Evidence status: Mouse study · Peer reviewed
A mouse study maps a lymphatic route that drains fluid from the back of the eye to a neck lymph node in 20 minutes. What it may mean for glaucoma.
news Earth Evidence status: Peer reviewed · Modelling study
A Geology paper models a kilometre-high cliff formed as Rodinia broke apart about 800–750 million years ago, estimating it stripped up to 8 km of rock near its edge but…
News Physics Evidence status: Peer reviewed · Quantum interferometry experiment
An atom-chip experiment measured the quantum phase of freely falling rubidium atoms and found behavior consistent with Einstein’s equivalence principle.
News Chemistry Evidence status: Peer reviewed · Laboratory materials study
A 3D-printed titanium–polymer lattice floated for months and stayed buoyant after cracking, though long-term ocean performance remains untested.
News Biology Evidence status: Peer reviewed · Genome-wide association study
A study of up to 1.14 million people linked 1,260 DNA variants to Big Five personality traits, but each effect was tiny and genes are not destiny.
News Astronomy Evidence status: Peer reviewed · Telescope observations
Hubble tracked an immense, evolving decagon-shaped atmospheric wave around Saturn’s south pole, creating a striking counterpart to its northern hexagon.
News Biology Evidence status: Peer reviewed · Mouse study
Semaglutide extended median lifespan by about 12% in older female mice, but the study does not show that Ozempic slows human aging.
News Chemistry Evidence status: Peer reviewed · Ultrafast spectroscopy and model-based reconstruction
Physics · Peer reviewed. Ultrafast measurements reconstruct an exciton contracting by about 25%—a new view of light-driven energy transport.
