Animal eyes have evolved to process behaviorally important visual information, but how retinas deal with statistical asymmetries in visual space remains poorly understood. Using hyperspectral imaging in the field, in vivo 2-photon imaging of retinal neurons, and anatomy, here we show that larval zebrafish use a highly anisotropic retina to asymmetrically survey their natural visual world. First, d

Three new U–Pb ID-TIMS isotopic ages confirm previous evidence for two geochemically distinct, early Mesoproterozoic pulses of mafic magmatism along the western margin of Laurentia. The first is a U–Pb baddeleyite age of 1590 ± 5 Ma from a dyke swarm in the Tobacco Root Mountains of western Laurentia. It is the first evidence for magmatism of this age in west-central Laurentia. The second is a U–P

Artikeln är en komparativ studie av historieundervisning vid amerikanska och svenska lärosäten. Skillnaderna till trots märks vissa gemensamma drag såsom att styrmekanismerna har blivit allt fler, vilket har inneburit att den enskilde läraren har fått allt mindre att säga till om, bland annat till följd av en marknadsanpassning av högre utbildning med fokus på mätbarhet och utvärderingar. Samtidig

Voice synthesis is a useful method for investigating the communicative role of different acoustic features. Although many text-to-speech systems are available, researchers of human nonverbal vocalizations and bioacousticians may profit from a dedicated simple tool for synthesizing and manipulating natural-sounding vocalizations. Soundgen (https://CRAN.R-project.org/package=soundgen) is an open-sou

In oviparous animals, maternally transferred antioxidants protect the embryo from oxidative damage from high rates of reactive oxygen species (ROS) production incurred by rapid growth. Elevated ROS exposure, beyond that incurred by normal growth, can occur as a result of exposure to exogenous factors (e.g. pollutants, toxins, radiation), increasing the risk of oxidative damage, with potentially ad

Satellite derived normalized difference vegetation index (NDVI) is a common data source for monitoring regional and global ecosystem properties. In dry lands it has contributed to estimation of inter-annual and seasonal vegetation dynamics and phenology. However, due to the spectral properties of NDVI it can be affected by clouds which can introduce missing data in the time series. Remotely sensed

The ignition processes in an ethylene-fueled supersonic combustor excited by laser-induced plasma (LIP) were investigated experimentally under the condition of inflow Ma number of 2.92. The LIP excitation was implemented near the center floor of a flameholding cavity. Optical measurements, including simultaneous CH∗/OH∗ chemiluminescence imaging and Schlieren photography, were used to investigate

Asthma is a common disease, and although its clinical manifestations may be similar among patients, recent research discoveries have shown that it consists of several distinct clinical clusters or phenotypes, each with different underlying molecular pathways yielding different treatment responses. Based on these observations, an alternative approach - known as ‘precision medicine’ - has been propo

With the arrival of the refugees from the Middle East, especially since 2015, Europe has become a xenophobic hotbed. Discourses, practices, and policies promoting and supporting xenophobia have become reality. In this article, we seek to present stories of those who have arrived to Europea via the Balkan Route, in a qualitative research fashion, concentrating on several narratives collected by the

Adopting a qualitative approach to the investigation of high achievement, the authors analyzed how high-achieving women in the Swedish workplace made meaning of positive and negative experiences in their work. The data consisted of interviews with 15 women identified as being high achieving in their respective field, and it was analyzed using grounded theory methodology. The women described five d
