    [Perspective] Hominid superorganisms (2016)

    Description: Mutualistic symbiotic relationships are those in which both species benefit; for example, the vivid colors of coral reefs come from symbiotic algae that provide their living coral hosts with nutrients and oxygen through photosynthesis in exchange for protection. A similar mutualistic relationship exists between gut-dwelling bacteria and their animal hosts (1). It remains unclear, however, to what degree symbiosis has shaped host-microbial interactions and coevolution. On page 380 of this issue, Moeller et al. show that gut bacterial strains cospeciated with hominids (apes and humans) over the past 15 million years (2). These findings set the stage for exploring the evolutionary processes that underlie the symbiotic relationship between hominids and their gut-dwelling microbes. Authors: Julia A. Segre, Nick Salafsky

    [In Depth] Comb jelly ‘anus’ guts ideas on origin of through-gut (2016)
    American Association for the Advancement of Science (AAAS)
    In: Science
    Details
    Publication Date: 2016-03-25
    Description: Several unprecedented videos of gelatinous sea creatures called comb jellies, or ctenophores, now threaten to upend the standard view of the evolution of the so-called through-gut. Comb jellies, jellyfish, sea sponges, and a few other creatures all were thought to lack an anus, which meant they had to eat and defecate through a single hole. These are descendants of some of the first animals to arise, so it has been thought that the through-gut and anus were an innovation that came after those lineages emerged—and perhaps something that drove the diversity of new animal forms. But on 15 March, at the Ctenopolooza meeting in St. Augustine, Florida, evolutionary biologist William Browne of the University of Miami in Florida debuted films of comb jellies pooping—and it wasn't through their mouths. Browne's videos elicited gasps from the audience, who is now rethinking when the through-gut first evolved—and whether it may have emerged more than once. Author: Amy Maxmen

    [Perspective] Disrupted nuclear import-export in neurodegeneration (2016)

    Publication Date: 2016-08-16
    Description: The major human neurodegenerative diseases, including Alzheimer's, amyotrophic lateral sclerosis, Parkinson's, and Huntington's diseases, are associated with accumulation and aggregation of misfolded proteins. In most cases, the majority of aberrantly aggregated proteins are found in the cell cytoplasm. However, in disorders caused by the expansion of a trinucleotide repeat, including Huntington's disease and spinocerebellar ataxia, the corresponding aggregates of proteins containing the encoded polyglutamine expansions are predominantly nuclear. Whether differences in intracellular location matter for the toxicity generated by such proteins has not been determined. On page 173 of this issue, Woerner et al. (1) report that the location does indeed matter, with toxicity arising from the cytoplasmic accumulation of a pair of artificial proteins designed to mimic the properties of amyloid aggregates. Surprisingly, forcing the same artificial proteins into the nucleus substantially reduces their toxicity. Authors: Sandrine Da Cruz, Don W. Cleveland

    [In Depth] Dogs may have been domesticated more than once (2016)
    American Association for the Advancement of Science (AAAS)
    In: Science
    Details
    Publication Date: 2016-06-03
    Description: For years, scientists have debated where dogs came from. Did wolves first forge their special relationship with humans in Europe, or in Asia? The answer, according to a new study, is yes. Researchers report that genetic analysis of hundreds of canines—including a nearly 5000-year-old dog unearthed on the east coast of Ireland—reveals that dogs may have been domesticated twice, once in Asia and once in Europe or the Near East, although European ancestry has mostly vanished from today's dogs. The findings could resolve a rift that has roiled the canine origins community—but experts say a lot more work needs to be done to confirm them. Author: David Grimm

    [Perspective] Visualizing evolution as it happens (2016)

    Publication Date: 2016-09-09
    Description: One of the greatest symbols of the birth of evolutionary biology is Darwin's first sketch of an evolutionary tree, above which he wrote: “I think.” Not only are evolutionary trees central to how scientists conceptualize evolutionary processes, Darwin's words also capture a key aspect of evolutionary science: It is difficult to observe, forcing researchers to rely heavily on inference. In recent decades, studies of fast-growing microorganisms have allowed hypotheses about evolutionary processes to be tested experimentally (1). On page 1147 of this issue, Baym et al. (2) report a device for visualizing evolutionary branching as bacteria grow across a meter-scale agar slab. The results offer important insights into evolutionary dynamics in spatially extended systems. Authors: Luke McNally, Sam P. Brown

    Lipopolysaccharide is transported to the cell surface by a membrane-to-membrane protein bridge (2018)
    American Association for the Advancement of Science (AAAS)
    In: Science
    Details
    Publication Date: 2018-02-16
    Description: Gram-negative bacteria have an outer membrane that serves as a barrier to noxious agents in the environment. This protective function is dependent on lipopolysaccharide, a large glycolipid located in the outer leaflet of the outer membrane. Lipopolysaccharide is synthesized at the cytoplasmic membrane and must be transported to the cell surface. To understand this transport process, we reconstituted membrane-to-membrane movement of lipopolysaccharide by incorporating purified inner and outer membrane transport complexes into separate proteoliposomes. Transport involved stable association between the inner and outer membrane proteoliposomes. Our results support a model in which lipopolysaccharide molecules are pushed one after the other in a PEZ dispenser–like manner across a protein bridge that connects the inner and outer membranes.
