Unraveling the Molecular Mechanisms Underlying Spontaneous Multipolar Mitosis Through CIN‐seq

Advanced Science, Volume 13, Issue 40, 17 July 2026.
Multipolar mitosis, a hallmark of chromosomal instability (CIN), drives tumor heterogeneity but is challenging to study in live cells. Using CIN‐seq, a single‐cell multiomics method, we profiled rare CIN events and identified mechanisms associated with viable multipolar mitosis, including PTEN attenuation, Rho GTPase‐driven cytokinesis failure, and ...

Diversity, abundance and niche differentiation of ammonia-oxidizing prokaryotes in mud deposits of the eastern China marginal seas

Frontiers in Microbiology, 2016
The eastern China marginal seas are prominent examples of river-dominated ocean margins, whose most characteristic feature is the existence of isolated mud patches on sandy sediments.

NITRIFICATION AND NITRIFYING BACTERIA IN A COASTAL MICROBIAL MAT

Frontiers in Microbiology, 2015
The first step of nitrification, the oxidation of ammonia to nitrite, can be performed by ammonia-oxidizing archaea (AOA) or ammonium-oxidizing bacteria (AOB).

The ecological dichotomy of ammonia-oxidizing archaea and bacteria in the hyper-arid soils of the Antarctic Dry Valleys

Frontiers in Microbiology, 2014
The McMurdo Dry Valleys of Antarctica are considered to be one of the most physically and chemically extreme terrestrial environments on the Earth. However, little is known about the organisms involved in nitrogen transformations in these environments ...

Migrating Bitcoin to AOB for Enhanced Security

Despite Bitcoin's success, its Proof-of-Work (PoW) consensus mechanism has inherent security vulnerabilities, as highlighted by a recent 51% attack on Monero in 2025. This paper proposes a solution: migrating Bitcoin to the Atomic Ownership Blockchains (AOB) framework.

AOB - Acoustic Oceanographic Buoy: concept and feasibility

, 2006
The AOB - Acoustic Oceanographic Buoy is the single node of a network of “smart” buoys for acoustic surveillance, Rapid Environmental Assessment (REA) and underwater communications. The AOB is a lightweight surface buoy with a vertical array of acoustic receivers and temperature sensors to be air dropped or hand deployed from a small boat. The received
