In Vitro Fertilization, State Wrongful Death Statutes and State Fetal Homicide Statutes: The Reaction to LePage v. Center for Reproductive Medicine.

The Alabama Supreme Court recently held, in , that the parents of human embryos that were negligently destroyed at a fertility clinic could bring an action for damages under the State's wrongful death statute. Although the Alabama legislature promptly enacted a law essentially overturning the state supreme court's decision, concerns have been raised that the court's decision might influence courts in other States to interpret their wrongful death statutes, or possibly even their fetal homicide statutes, to apply in similar circumstances, thereby threatening the availability of fertilization (IVF) technology. This article addresses those concerns.

New Approaches to 3D Vision.

New approaches to 3D vision are enabling new advances in artificial intelligence and autonomous vehicles, a better understanding of how animals navigate the 3D world, and new insights into human perception in virtual and augmented reality. Whilst traditional approaches to 3D vision in computer vision (SLAM: simultaneous localization and mapping), animal navigation (cognitive maps), and human vision (optimal cue integration) start from the assumption that the aim of 3D vision is to provide an accurate 3D model of the world, the new approaches to 3D vision explored in this issue challenge this assumption. Instead, they investigate the possibility that computer vision, animal navigation, and human vision can rely on partial or distorted models or no model at all.

Minimal theory of 3D vision: new approach to visual scale and visual shape.

Since Kepler and Descartes in the early-1600s, vision science has been committed to a triangulation model of stereo vision. But in the early-1800s, we realized that disparities are responsible for stereo vision. And we have spent the past 200 years trying to shoe-horn disparities back into the triangulation account.

V1 as an egocentric cognitive map.

We typically distinguish between V1 as an egocentric perceptual map and the hippocampus as an allocentric cognitive map. In this article, we argue that V1 also functions as a post-perceptual egocentric cognitive map. We argue that three well-documented functions of V1, namely (i) the estimation of distance, (ii) the estimation of size, and (iii) multisensory integration, are better understood as post-perceptual cognitive inferences.

Does Vergence Affect Perceived Size?

Since Kepler (1604) and Descartes (1637), it has been suggested that 'vergence' (the angular rotation of the eyes) plays a key role in size constancy. However, this has never been tested divorced from confounding cues such as changes in the retinal image. In our experiment, participants viewed a target which grew or shrank in size over 5 s.

Does vision extract absolute distance from vergence?

Since Kepler (1604) and Descartes (1637), 'vergence' (the angular rotation of the eyes) has been thought of as one of our most important absolute distance cues. But vergence has never been tested as an absolute distance cue divorced from obvious confounding cues such as binocular disparity. In this article, we control for these confounding cues for the first time by gradually manipulating vergence and find that observers fail to accurately judge distance from vergence.

Medical Emergency Exceptions in State Abortion Statutes: The Statistical Record.

This article attempts to determine, first, whether emergency exceptions in statutes regulating abortion have been abused and, second, whether the standard used in such an exception--subjective or objective--makes a difference in the reported incidence of such emergencies. A review of the statistical data supports two conclusions. First, physicians who perform abortions and have complied with state reporting requirements have not relied upon the medical emergency exceptions in state abortion statutes to evade the requirements of those statutes.
