Taboo ecologies: material and lyric dispossession in Anne Spencer’s garden and seed catalogs
Harlem Renaissance poet and gardener Anne Spencer drew inspiration from both her garden and
reading. In a poem entitled “Taboo,” Spencer described reading “garden and seed catalogs, Browning,
Housman, Whitman […] oh anything…” and, in doing so, asserted the significance of her catalogs alongside literary works as inspiration for her poetry. The poem as a whole describes how Black women evade the Jim Crow South through covert activities like reading which for Spencer, importantly included garden and seed catalogs. Where Spencer’s poetry and garden have been the subject of academic research, her catalogs have yet to receive the same scholarly attention. This paper argues that by placing garden and seed catalogs in the same category of taboo reading as canonical poets and conventional forms of journalism, Spencer aligns the botanical with the literary as a form of resistance. The seed catalogs Spencer engaged with reveal a long history of racism in the cultivation and naming of garden plants. This paper examines the history of seed catalogs, showing how the naming of plants is a continuation of the racist logic of possession, reflected in the naming of plants by stripping the plant of its previous context and replacing it with the names of colonial scientists and racial slurs. Spencer’s poetic insistence on dispossession, the literal and metaphorical disembodiment and ejection from property, pushes against conceptions of ownership over the natural world in that it subverts the racist logic of possession. I contend that Anne Spencer actively intertwined histories by drawing on catalogs, poetry, and gardening to create new ecologies in the spaces between reading and writing, lyrical and material. The new ecology of Spencer’s garden far exceeds a place where plants are grown but rather becomes a space that blooms through the material, the lyrical, and social spaces, leaving behind instead a living archive of rebellion.La poeta y jardinera del renacimiento de Harlem, Anne Spencer, se inspiraba tanto en su jardín
como en la lectura. En un poema titulado “Taboo”, Spencer describió leer “catálogos de jardinería y semillas, Browning, Housman, Whitman […] oh, cualquier cosa…” y, al hacerlo, afirmó la importancia de sus catálogos, así como la de las obras literarias como inspiración para su poesía. Su poema como un todo describe cómo las mujeres negras se evadían del sur de Jim Crow a través de actividades encubiertas como la lectura, lo que para Spencer incluía de forma importante los catálogos de jardinería y semillas. Mientras que la poesía y la jardinería de Spencer han sido materia de investigación académica, sus catálogos aún no han recibido la misma atención intelectual. Este artículo sostiene que al situar los catálogos de jardinería y semillas en la misma categoría de lectura tabú que a los poetas canónicos y las formas convencionales de periodismo, Spencer alinea lo botánico con lo literario como forma de resistencia. Los catálogos de semillas con los que interactuaba Spencer revelaban una larga historia de racismo en el cultivo y denominación de las plantas de jardín. A lo largo de este trabajo se examina la historia de los catálogos de semillas, mostrando cómo la denominación de las plantas es una continuación de la lógica racista de la posesión, reflejada en la nomenclatura de las plantas al desvincular a la planta de su contexto previo y reemplazarlo con los nombres de científicos coloniales y calumnias raciales. La insistencia poética de Spencer en la expropiación, en la desmaterialización literal y metafórica y en la expulsión de la propiedad se opone a las concepciones de pertenencia sobre el mundo natural al subvertir la lógica racista de la posesión. Sostengo que Anne Spencer entrelazaba activamente las historias recurriendo a los catálogos, la poesía y la jardinería para crear nuevas ecologías en los espacios entre la lectura y la escritura, lo lírico y lo material. La nueva ecología del jardín de Spencer va mucho más allá de un lugar donde se cultivan plantas para convertirse en un espacio que florece a través de los espacios materiales, líricos y sociales, dejando atrás un archivo vivo de rebelión

Synonymous Codon Pair Recoding of the HIV-1 env Gene Affects Virus Replication Capacity
Synonymous codon pair deoptimization is an efficient strategy for virus attenuation; however, the underlying mechanism remains controversial. Here, we optimized and deoptimized the codon pair bias (CPB) of the human immunodeficiency virus type 1 (HIV-1) envelope (env) gene to investigate the influence of env synonymous CPB recoding on virus replication capacity, as well as the potential mechanism. We found that env CPB deoptimization did not always generate attenuation, whereas CPB optimization attenuated virus replication in MT-4 cells. Furthermore, virus attenuation correlated with reduced Env protein production but not with decreased viral RNA synthesis. Remarkably, in our model, increasing the number of CpG dinucleotides in the 5' end of env did not reduce the replication capacity of HIV-1. These results indicate that factors other than CPB or CpG content may have impacted the viral fitness of the synonymously recoded study variants. Our findings provide evidence that CPB recoding-associated attenuation can affect translation efficiency. Moreover, we demonstrated that an increased number of CpGs in the 5' end of HIV-1 env is not always associated with reduced virus replication capacity
Stationary components of HeI in strong magnetic fields - a tool to identify magnetic DB white dwarfs
In only three of the 61 known magnetic white dwarfs helium has been
identified unambiguously while about 20% of all non-magnetic stars of this
class are known to contain HeI or HeII. Until recently, data for HeI data were
available only for magnetic fields below 20MG. This changed with the
publication of extensive data by the group in Heidelberg. The corresponding
calculations have now been completed for the energetically lowest five states
of singlet and triplet symmetry for the subspaces with |m| <= 3; selected
calculations have been performed for even higher excitations. In strongly
magnetized white dwarfs only line components are visible whose wavelengths vary
slowly with respect to the magnetic field, particularly stationary components
which have a wavelength minimum or maximum in the range of the magnetic fields
strengths on the stellar surface. In view of the many ongoing surveys finding
white dwarfs we want to provide the astronomical community with a tool to
identify helium in white dwarfs for fields up to 5.3GG. To this end we present
all calculated helium line components whose wavelengths in the UV, optical, and
near IR vary slowly enough with respect to the field strength to produce
visible absorption features. We also list all stationary line components in
this spectral range. Finally, we find series of minima and maxima which occur
as a result of series of extremal transitions to increasingly higher
excitations. We estimated the limits for 8 series which can possibly give rise
to additional absorption in white dwarf spectra; one strong absorption feature
in GD229 which is yet unexplained by stationary components is very close to two
estimated series limits.Comment: 8 pages, 2 figures, accepted for publication by Astronomy and

The stability of poloidal magnetic fields in rotating stars
The stability of large-scale magnetic fields in rotating stars is explored,
using 3D numerical hydrodynamics to follow the evolution of an initial poloidal
field. It is found that the field is subject to an instability, located
initially on the magnetic equator, whereby the gas is displaced in a direction
parallel to the magnetic axis. If the magnetic axis is parallel to the rotation
axis, the rotation does not affect the initial linear growth of the
instability, but does restrict the growth of the instability outside of the
equatorial zone. The magnetic energy decays on a timescale which is a function
of the Alfv\'en crossing time and the rotation speed, but short compared to any
evolutionary timescale. No evidence is found for a possible stable end state to
evolve from an initial axisymmetric poloidal field. The field of an oblique
rotator is similarly unstable, in both cases regardless of the rotation speed.Comment: A&A accepted. Animations available at

Impact of Synonymous Genome Recoding on the HIV Life Cycle
Synonymous mutations within protein coding regions introduce changes in DNA or messenger (m) RNA, without mutating the encoded proteins. Synonymous recoding of virus genomes has facilitated the identification of previously unknown virus biological features. Moreover, large-scale synonymous recoding of the genome of human immunodeficiency virus type 1 (HIV-1) has elucidated new antiviral mechanisms within the innate immune response, and has improved our knowledge of new functional virus genome structures, the relevance of codon usage for the temporal regulation of viral gene expression, and HIV-1 mutational robustness and adaptability. Continuous improvements in our understanding of the impacts of synonymous substitutions on virus phenotype - coupled with the decreased cost of chemically synthesizing DNA and improved methods for assembling DNA fragments - have enhanced our ability to identify potential HIV-1 and host factors and other aspects involved in the infection process. In this review, we address how silent mutagenesis impacts HIV-1 phenotype and replication capacity. We also discuss the general potential of synonymous recoding of the HIV-1 genome to elucidate unknown aspects of the virus life cycle, and to identify new therapeutic targets
