    Notes: [Auszug] Genetic recombination is known to be a source of mitochondrial DNA (mtDNA) variability in plants, fungi and protists1, but there continues to be a consensus (based on studies of somatic cell hybridization2 and DNA repair3) that such processes do not operate on animal mtDNA4. Contrary to this ...

    Notes: [Auszug] Sir-Why are advertisements for PhD students specifically directed at those who are "under 30" or a "young student"? I am surprised that a journal such as Nature should support such discrimination. Indeed, it may conflict with equal opportunities legislation. I am a mature student, one of many ...

    Notes: [Auszug] The importance of latent reservoirs for HIV-1 is highlighted by studies of potent antiretroviral drugs that block new rounds of infection and produce a dramatic drop in plasma virus in two weeks. The rapid decline shows that virus production results largely from continuous rounds of virus infection ...

    Notes: [Auszug] North Atlantic Deep Water possesses a distinct physical, chemical and isotopic signature (see, for example, refs 4, 13-15). In particular, the sources of NADW impart an extremely unradiogenic Nd isotope composition (eNd = - 13.5 ± 0.5 (ref. 15), where eNd is the measured 143Nd/144Nd ratio ...

    Notes: [Auszug] A general strategy for learning is to divide a complex task into simpler subtasks and learn each subtask with a separate module. This strategy has been formalized into a computational model of learning known as the mixture of experts1, in which a set of expert modules each learn one of the subtasks ...

    Notes: [Auszug] In many taxa, parents compensate for the overproduction of young by conferring vital advantages on certain offspring, enabling them to out-compete their siblings when resources are scarce1'2. With birds, the competitive advantage is usually related to the age of chicks, which varies because of ...

    Notes: [Auszug] The primary role of the X-inactivation centre is to initiate X-chromosome inactivation, leading to a spread of inactivation up and down the X chromosome2'3. In addition, the Xic senses whether the cell contains one or more X chromosomes and therefore whether or not it should initiate X ...
