Get Instant Summarized Text (Gist) Sleep disorders and hearing loss are linked by shared biological mechanisms. Different sleep stages affect auditory perception, and hearing loss can disrupt ...

The cross-correlation of high-frequency ambient noise (>1 Hz) is usually interpreted as the empirical Green’s function between two stations and used for imaging the near surface. However, ...

These findings led researchers to propose that E. coli has an alternative, back-up mechanism for initiating replication (Hinds and Sandler, 2004). Previous studies have suggested that a protein called ...

For context, OpenAI's Codex Mini, o3, and o4-mini models managed to bypass the shutdown commands and mechanisms. Codex sabotaged the mechanism 12 times, while o3 bypassed the shutdown command 7 times.

Limona ketone, as a significant intermediate in the oxidation of limonene, plays a crucial role in environmental and human health impacts. In this article, we present a study on the reaction kinetics ...

The Council adopted today its negotiating position (general approach) on one of the proposals of the so-called ‘Omnibus I’ legislative package, which simplifies and strengthens the EU’s carbon border ...
