Phys.org / Self-regulating process governs cosmic order inside star clusters

A team of astrophysicists from Nanjing University and University of Bonn have demonstrated that, rather than being random, the mass of new stars born inside a star cluster is actually governed by a defined process of self-regulation. ...

Phys.org / Chromosomes condense in three timed chemical waves during cell division, study shows

DNA does not float freely in the cell. Instead, it is wrapped around histone proteins to form structures called nucleosomes. These histones carry numerous chemical modifications that act as molecular signals, controlling ...

Phys.org / A mother's gift: Plastid-derived structures help sea urchin development and dispersal

During the development of marine organisms—from fertilization through to juvenile stages—it is often observed that the eggs released into the water column are initially supplied with only a small fraction of the energy they ...

Medical Xpress / Label-free optical imaging enables automated measurement of human white matter microstructure

White matter pathways allow distant parts of the brain to communicate, supporting memory, emotion, and language. One such pathway, the uncinate fasciculus, connects the front of the temporal lobe with regions of the frontal ...

Phys.org / Low wages, poor training put security guards—and the public—at risk, study finds

Tens of thousands of private security guards in California play a critical role in public safety, but poverty-level wages and poor training put both the guards and the public at risk, according to a new study by the UC Berkeley ...

Phys.org / One blue whale song unlocks oceans of data

Trying to find a whale song in the ocean is like trying to find a needle in a haystack. But now, UNSW Sydney researchers say they've trained a model, with just a single case study, to find blue whale songs in recordings that ...
