Rats act as if they expect that the delays associated with temporal cues will covary due to a common causal factor.

Extraembryonic tissue spreading in the scuttle fly Megaselia abdita requires mechanical decoupling from the underlying yolk sac.

Use of experimental manipulation demonstrates that social/solitary feeding behaviors are unrelated to the fitness gains conferred by causative alleles in two previously identified genes.

Skeletal muscle performance sets the course of rapid speciation by defining the evolutionary trajectory of reproductive behavior.

The genetic make-up of dominating MDR-TB clades in Central Asia is shaped by programmatic and socio-economic changes that led to fixation of resistance and bacterial fitness related mutations in the Soviet era.

The evolution of the light-sensitive visual pigment rhodopsin involved functional tradeoffs that may have sacrificed rod photosensitivity for active-state protein stability to mitigate phototoxicity in tetrapods, but not in fishes.

The evolutionary loss of the main enzyme required for ketone body biosynthesis suggests that alternative strategies to provide energy for large brains during fasting evolved repeatedly in mammals.

Elephants and fruit bats have evolved large brains even though they have lost a gene that is fundamental to the supply of energy to the brain when glucose is not available.

The discovery of a biological switching valve provides an example of a mechanism that evolved in nature long before its invention by man and could inspire alternative valve technologies.

Flying squirrels may have originated earlier than previously thought and remained unchanged for almost 12 million years.
