Within-host speciation of malaria parasites

Background Sympatric speciation—the divergence of populations into new species in absence of geographic barriers to hybridization—is the most debated mode of diversification of life forms. Parasitic organisms are prominent models for sympatric speciation, because they may colonise new hosts within the same geographic area and diverge through host specialization. However, it has been argued that th

Tankens frihet och biologins gränser

När vi talar om framsteg, tänker vi inte bara på teknik och ökad kunskap. Vi tror att kunskapen automatiskt leder till en bättre framtid. Och visst har tankens frihet givit oss makt. Men vi är inte så fria som vi tror.

Alexithymia in sleep disorder patients.

The purpose of the present study was to study associations between self-assessed alexithymia and sleep disorders. Five groups of patients with different sleep disorders were compared on the Toronto Alexithymia Scale (TAS-20). The prevalence of alexithymia, as defined by the cut-off score of TAS >60 was 17% among all patients, but differed among the groups: Primary Insomnia (PRI, n = 119) 6.7%, Ins

Human eeg responses to exact and statistical fractal patterns.

Attention Restoration Theory point to nature as a particularly good candidate for restoring the ability to focus and inhibit distractions. However, little effort has been directed to elaborating on what makes nature's visual pattern unique for restoration purposes. One suggested explanation is the fractal properties of natural patterns (Hagerhall, 2005). Both perception studies (Hagerhall et al.,

Probing control in B. licheniformis fermentations

This paper presents the implementation of the probing control technique in an industrially relevant fed-batch fermentation process utilizing the microorganism Bacillus lichenifor has been done in pilot-scale experiments. The aim of the work is firstly to find out whether it is posuccessfully implement probing control in B. licheniformis fermentations. Secondly, it is to find out whing control can
