Rotational breakup as the origin of small binary asteroids pp188-191
Binary asteroids are created by the slow spin up of a 'rubble pile'
asteroid via the thermal YORP effect (where radiation from an
irregularly shaped body exerts a net force on the body). The mass shed
from the equator of a critically spinning body accretes into a
satellite if the material is collisionally dissipative.

A report providing improved limits on the indigenous volatile contents

The best estimate of the pre eruptive water content of the lunar

volatile elements, including water.

While electric dipole transitions at the atoms are reduced in the

The evolutionary origin of flatfish asymmetry pp209-212
A re-examination of the Eocene fish Amphistium and a description of a
new genus prove that they are the most primitive members of the

than the dorsal midline, even in fully adult fishes, providing perhaps
the most graphic and dramatic examples known of a transitional form
spotted in the fossil record.

Social diversity promotes the emergence of cooperation in public goods
games pp213-216
Humans often cooperate with each other, but the temptation to forgo
the public good mostly wins over collective cooperative action. Many
existing models treat individuals as equivalent, ignoring diversity
and population structure; however, here it's shown theoretically that
social diversity, introduced via heterogeneous graphs, promotes the
emergence of cooperation in public goods games.

the peripheral blood of Nix-/- mice exhibited mitochondrial retention
and reduced lifespan in vivo.

Imaging the biogenesis of individual HIV-1 virions in live cells p236
This study uses several techniques based on total internal reflection
fluorescence microscopy and live cells expressing fluorescent-protein
tagged derivatives of Gag, the major structural component of HIV 1,
to observe and quantitatively describe the assembly of individual
virus particles in real time.

Mei-P26 regulates microRNAs and cell growth in the Drosophila ovarian
stem cell lineage p241
This paper shows that the Trim NHL protein Mei P26 restricts growth
and proliferation in the ovarian stem cell lineage. In mei P26
mutants, transit-amplifying cells are larger and proliferate
indefinitely, leading to the formation of an ovarian tumour.

Laboratory Investigation presents:
'Understanding the development of human bladder cancer by using a
whole-organ genomic mapping strategy'

Can this disease be detected earlier? Genome-wide mapping of human
bladder cancer has identified key genetic risk areas for cancer
development and provides new insight into early genetic origins of cancer.
