   Brain Size: Gene losses did not stop the evolution of big brains

   Cristian Cañestro, Vittoria Roncalli

   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.

   Recurrent loss of HMGCS2 shows that ketogenesis is not essential for the evolution of large mammalian brains

   David Jebb, Michael Hiller

   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.

   A biological switching valve evolved in the female of a sex-role reversed cave insect to receive multiple seminal packages

   Kazunori Yoshizawa et al.

   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.

   Oldest skeleton of a fossil flying squirrel casts new light on the phylogeny of the group

   Isaac Casanovas-Vilar et al.

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

   Intrinsic cooperativity potentiates parallel cis-regulatory evolution

   Trevor R Sorrells et al.

   Cooperativity between two transcription regulators occurs through protein-protein interactions with a general transcription factor complex and potentiates the parallel evolution of their DNA binding sites.

   Enhanced ER proteostasis and temperature differentially impact the mutational tolerance of influenza hemagglutinin

   Angela M Phillips et al.

   Endoplasmic reticulum proteostasis factors enhance the mutational tolerance of influenza hemagglutinin, a model secretory pathway protein and therapeutic target, particularly improving the fitness of temperature-sensitive variants.

   Decoupled maternal and zygotic genetic effects shape the evolution of development

   Christina Zakas et al.

   Early development involves both maternal and zygotic genetic effects. This dual genetic basis shapes the evolution of developmental mode in a marine annelid.

    A SoxB gene acts as an anterior gap gene and regulates posterior segment addition in a spider

    Christian Louis Bonatto Paese et al.

    Sox21b-1 regulates simultaneous formation of anterior segments and addition of posterior segments in a spider, which resembles segmentation in long- and short-germ insects, and suggests SoxB regulation of segmentation is an ancestral feature of arthropods.
