• [Evolution] Inaugural Articles: Interrogating an insect society
Insect societies such as those of ants, bees, and wasps consist of 1 or a small number of fertile queens...
• [Astronomy] Pristine extraterrestrial material with unprecedented nitrogen is...
Pristine meteoritic materials carry light element isotopic fractionations that constrain physiochemical conditions during solar system formation. Here we report the...
• [Evolution] Model criticism based on likelihood-free inference, with an appli...
Mathematical models are an important tool to explain and comprehend complex phenomena, and unparalleled computational advances enable us to easily...
• [Evolution] Paleocene emergence of elephant relatives and the rapid radiation...
Elephants are the only living representatives of the Proboscidea, a formerly diverse mammalian order whose history began with the 55-million...
• [Neuroscience] Motivational states activate distinct hippocampal representati...
Adaptive behaviors are guided by motivation and memory. Motivational states specify goals, and memory can inform motivated behavior by providing...
• [Psychology] The proper treatment of language acquisition and change in a pop...
Language acquisition maps linguistic experience, primary linguistic data (PLD), onto linguistic knowledge, a grammar. Classically, computational models of language acquisition...
• [Cell_Biology] JFK, a Kelch domain-containing F-box protein, links the SCF co...
The p53 tumor suppressor plays a central role in integrating cellular responses to various stresses. Tight regulation of p53 is...
• [Evolution] Extreme inbreeding in Leishmania braziliensis
Leishmania species of the subgenus Viannia and especially Leishmania braziliensis are responsible for a large proportion of New World leishmaniasis...
• [Evolution] Natural colonization and adaptation of a mosquito species in Gala...
Emerging infectious diseases of wildlife have been recognized as a major threat to global biodiversity. Endemic species on isolated oceanic...
• [Immunology] Tie2cre-induced inactivation of the miRNA-processing enzyme Dice...
MicroRNAs (miRNAs) are a class of evolutionarily conserved small noncoding RNAs that are increasingly being recognized as important regulators of...
• [Neuroscience] Key role of coupling, delay, and noise in resting brain fluctu...
A growing body of neuroimaging research has documented that, in the absence of an explicit task, the brain shows temporally...
• [Neuroscience] Localized olfactory representation in mushroom bodies of Droso...
Odor discrimination in higher brain centers is essential for behavioral responses to odors. One such center is the mushroom body...
• [Evolution] Inaugural Article: Controls on development and diversity of Early...
The 3,450-million-year-old Strelley Pool Formation in Western Australia contains a reef-like assembly of laminated sedimentary accretion structures (stromatolites) that have...
• [Evolution] Statistical mechanics of convergent evolution in spatial patterning
We explore how the genotype–phenotype map determines convergent evolution in a simple model of spatial gene regulation during development. Evolution...
• [Astronomy] Atmospheric pressure as a natural climate regulator for a terrest...
Lovelock and Whitfield suggested in 1982 that, as the luminosity of the Sun increases over its life cycle, biologically enhanced...
• [Engineering] Engineering size-scaling of plastic deformation in nanoscale as...
Size-dependent plastic flow behavior is manifested in nanoindentation, microbending, and pillar-compression experiments and plays a key role in the contact...
• [Evolution] A primate subfamily of galectins expressed at the maternal-fetal ...
Galectins are proteins that regulate immune responses through the recognition of cell-surface glycans. We present evidence that 16 human galectin...
• [Evolution] Genomic linkage of male song and female acoustic preference QTL u...
The genetic coupling hypothesis of signal-preference evolution, whereby the same genes control male signal and female preference for that signal,...
• [Evolution] A Mullerian mimicry ring in Appalachian millipedes
Few biological phenomena provide such an elegant and straightforward example of evolution by natural selection as color mimicry among unrelated...
