Unlocking the chromosome

Advances in our understanding of basic biological processes and human disease owe much to the groundbreaking research of scientists at the Chromosome Dynamics Laboratory at RIKEN Advanced Science Institute.

The determining factors of cell shape examined

A European team is investigating the role of the bacterial cell wall and the cytoskeleton in mediating cell shape. Results are expected to have broader implications for cell biology.

Dating encounters between modern humans and Neandertals

To discover why Neandertals are most closely related to people outside Africa, Harvard and Max Planck Institute scientists have estimated the date when Neandertals and modern Europeans last shared ancestors. The research, ...

Oocytes: Going with the flow

Most cells rely on structural tethers to position chromosomes in preparation for cell division. Not so oocytes. Instead, a powerful intracellular stream pushes chromosomes far-off the center in preparation for the highly ...

The women scientists forgotten by history

French doctor and researcher Marthe Gautier, who died over the weekend, was one of a long line of women scientists who greatly contributed to scientific discovery only to see the credit go to their male colleagues.

Study shows how epigenetic memory is passed across generations

A growing body of evidence suggests that environmental stresses can cause changes in gene expression that are transmitted from parents to their offspring, making "epigenetics" a hot topic. Epigenetic modifications do not ...

Biologists identify reproductive 'traffic cop'

Before an egg becomes fertilized, sets of chromosomes must pair up to pass along genetic information. This happens within each reproductive cell, where separate chromosomes of male and female origin move toward each other ...

How chromosomes evolve to create new forms of life

3-D printing is a universal process in the sense that pretty much any part that can be drawn up in a CAD program can be printed, at least within a certain resolution. Machining a part on a mill or lathe, while having the ...
