    • Abstract:  Wolbachia symbionts are obligate intracellular bacteria that cause host reproductive alterations in many arthropods and filarial nematodes. We identified Wolbachia symbionts in the cliff swallow bug (Oeciacus vicarious Horvath) and the human bed bug (Cimex lectularius L.) (Hemiptera: Cimicidae) by polymerase chain reaction (PCR) amplification and sequencing using Wolbachia-specific 16S rDNA and FtsZ primers. Phylogenetic analyses using Bayesian, maximum likelihood, and maximum parsimony algorithms indicated, with strong support, that (1) Wolbachia infections in these two cimicid hosts form a monophyletic group, and (2) the Wolbachia strains detected belong to the F clade, previously associated with termites, weevils, and filarial nematodes.

          • API for Statistical Phylogenetics with HPC
            Researchers at the University of Maryland have developed BEAGLE, an application programming interface and specialized library for high-performance statistical phylogenetic inference that allows existing software packages to make more effective use of available computer hardware including GPUs, CPUs with Streaming SIMD Extensions, and multi-core CPUs via OpenMP.
          • Genetic information migrates from plant to plant
            To generate phylogenetic trees and investigate relationships between organisms, scientists usually look for similarities and differences in the DNA. Plant scientists were confounded by the fact that the DNA extracted from the plants’ green chloroplasts sometimes showed the greatest similarities when related species grew in the same area. Scientists have now discovered that a transfer of entire ...

            In a study published in the latest issue of of Vertebrata PalAsiatic 2012(1), Dr. DENG Tao, Institute of Vertebrate Paleontology and Paleoanthropology (IVPP), Chinese Academy of Sciences in Beijing, reported a skull of Hipparion (Proboscidipparion) sinense from the Longdan locality in Dongxiang, Gansu Province, northwestern China. The previously known material of this species in the Early ...
          • New basal beaked ornithurine bird found from the lower cretaceous of Western Liaoning, China
            Based on a well-preserved specimen from the Lower Cretaceous Jiufotang Formation in Jianchang, western Liaoning, China, Paleontologists of Institute of Vertebrate Paleontology and Paleoanthropology (IVPP), Chinese Academy of Sciences reported a new species of basal ornithurine bird, Schizooura lii gen. et sp. nov., in the latest issue of Vertebrata PalAsiatic 2012(1), helping better understand ...
          • Out of Africa and out of Siberia | Gene Expression
            The latest edition of The American Journal of Human Genetics has two papers using “old fashioned” uniparental markers to trace human migration out of Africa and Siberia respectively. I say old fashioned because the peak novelty of these techniques was around 10 years ago, before dense autosomal SNP marker analyses, let alone whole genome sequencing. [...]
          • Following the shifting of tectonic plates to understand Mediterranean biodiversity
            Around 30 millions years ago, the Western Mediterranean basin opened as a result of the tectonic collision of the African and Eurasian plates. This geologic event was the starting point for the diversification of an endemic group of Western Mediterranean spiders, as has been demonstrated by a new study.

            The Pith: More caveman admixture in modern humans, especially Melanesians! A new paper on archaic adaptive introgression among Melanesians has been discussed elsewhere. But I think it is worth reviewing, because it’s probably a foretaste of what’s to come. Researchers are combing through the human genome, as more and more genomes come on line, in [...]
