important role in developing new treatments for fungal diseases such as athlete’s foot. “Fungi have a different mechanism from that of animals to produce lysine,” the reporter explained, “so if a drug can be developed that can disable the gene, it should be possible to treat people for fungal diseases without affecting their ability to make lysine”. The writer was presumably unaware that lysine...

The early modern emphasis on tradition is perhaps clearest in the history of women during this period, as at the core of each culture was an ingrained patriarchy dating back thousands of years. In the West, for example, attitudes towards women were shaped by three strains of ancient European tradition: first, Judeo-Christian belief, which characterized women as either saintly, like the Virgin M...

dramatic, and it rings true. A very quiet patient consults a physician about her headaches, and, in her body, emerges an unsuspected and Utterly different second personality, and then, amazingly, a third.

We have calculated the consensus sequence for human mitochondrial DNA using over 800 available sequences. Analysis of this consensus reveals an unexpected lack of diversity within human mtDNA worldwide. Not only is more than 83% of the mitochondrial genome invariant, but in over 99% of the variable positions, the majority allele was found in at least 90% of the individuals. In the remaining 0.2...

Anterior-posterior (AP) body segmentation of the fruit fly (Drosophila) is first seen in the 7-stripe spatial expression patterns of the pair-rule genes, which regulate downstream genes determining specific segment identities. Regulation of pair-rule expression has been extensively studied for the even-skipped (eve) gene. Recent live imaging, of a reporter for the 2nd eve stripe, has demonstrat...

The deleterious effects of different X-chromosome dosage in males and females are buffered by a process called dosage compensation, which in Drosophila is achieved through a doubling of X-linked transcription in males. The male-specific lethal complex mediates this process, but is known to act only after gastrulation. Recent work has shown that the transcription of X-linked genes is also upregu...

Patterning of the posterior end in animals is not well understood. Homologs of Drosophila even-skipped (eve) have a similar posterior expression pattern in many animals, and in vertebrates they are linked physically to the "posterior" ends of homeotic clusters (HOM-C), suggesting a conserved role in posterior development. However, the function of this posterior expression is not known. Here I s...

In this paper, we concentrate on the very recently proposed Measurement Device Independent Quantum Key Distribution (MDI QKD) protocol by Lo, Curty and Qi (PRL, 2012). In this protocol, a secret key is established between Alice and Bob with the help of an untrusted third-party called Eve. We study how one can suitably mount a symmetric incoherent eavesdropping strategy on MDI QKD considering th...
