Cosmology: Out of the darkness

Seeing Darkness: The New Cosmology

We present some useful ways to visualize the nature of dark energy and the effects of the accelerating expansion on cosmological quantities. Expansion probes such as Type Ia supernovae distances and growth probes such as weak gravitational lensing and the evolution of large scale structure provide powerful tests in complementarity. We present a “ladder” diagram, showing that in addition to dram...

Cutaneous lupus vulgaris: Bringing the wolf out of the darkness

Lupus vulgaris is the commonest form of cutaneous tuberculosis accounting for about 75% of the cases. Clinical dermatologists need to be aware of the myriad clinical presentations of this condition as it can be misdiagnosed especially when the index of suspicion is low. It is important to make a diagnosis and promptly treat as it can be disfiguring and destructive. Introduction Tuberculosis (TB...

Out of darkness: long non-coding RNAs come of age

It has been known for a number of years that only about 2% of this RNA encodes proteins. However, numerous studies employing both tiling arrays and high-throughput sequencing found that the genome is pervasively transcribed, with most DNA copied, at least at some point in time, into RNA. Indeed, Birney et al. (2007) estimated that 93% of the human genome is transcribed. Because of a dearth of f...

Virtual Reality Exposure Therapy for the Treatment of Darkness Phobia

Virtual reality (VR) exposure therapy is a common treatment for phobia and the efficacy of this technique has proved. The darkness phobia is one of the most common disorders among the children. This is the first research about the darkness phobia and using VR to treat the patients. The VR system designed in this article is composed from two parts: Mechatronic devices and graphics unit. As a chi...
