NEWS AND VIEWS
----------------------
Animal behaviour: Trust in fish
A mutually beneficial interaction between two species of fish turns out to
involve the careful appraisal of one by the other -- and the appropriately
virtuous behaviour by the former while being watched.
Lee Alan Dugatkin
http://www.nature.com/nature/journal/v441/n7096/full/441937a.html

Astrophysics: Magnetic accretion
Disks of hot gas drawn onto a central star or black hole are the best
energy-producing machines in the Universe. So how do these accretion disks
work? The answer, it seems, is blowing in their winds.
Daniel Proga
http://www.nature.com/nature/journal/v441/n7096/full/441938a.html

Cell biology: The Golgi grows up
The Golgi apparatus of the cell has long baffled biologists, mainly because
it is unclear how proteins are conveyed through it on their way to the cell
surface. Some innovative microscopy may resolve the issue.
Vivek Malhotra and Satyajit Mayor
http://www.nature.com/nature/journal/v441/n7096/full/441939a.html

Plant biology: Designs on Rubisco
Rubisco is said to be both the most important enzyme on Earth and
surprisingly inefficient. Yet an understanding of the reaction by which it
fixes CO2 suggests that evolution has made the best of a bad job.
Howard Griffiths
http://www.nature.com/nature/journal/v441/n7096/full/441940a.html

Materials science: Relaxors go critical
Relaxor ferroelectrics are fascinating and useful materials, but they seem
to be heterogeneous, hopeless messes. Observing what they do under electric
fields reveals critical behaviour that helps to make sense of them.
R. E. Cohen
http://www.nature.com/nature/journal/v441/n7096/full/441941a.html

Immunology: A second chance for the thymus Each organ develops at its own
time -- usually in the embryo. The discovery of progenitor cells that give
rise to two structures in the thymus hints that this immune organ can
continue to develop after birth.
Hans-Reimer Rodewald
