Rare immunodeficiency provides new insight into immune system function
... cytokine production in the SAP mutants. "Our data argue that a SAP/Fyn pathway may be required for the efficient recruitment of PKC-q and Bcl-10, as well as proper patterns of activation of NF-kB, and suggest a potentially novel pathway of T helper cell cytokine activation," offers Dr. Schwartzberg. A sep...Scientists advocate genomic sequencing of 'living fossil'
...on event. For these reasons, Myers and colleagues argue that the complete genomic sequence of the coelacanth would be valuable for identifying important genome modifications that occurred during the evolution of tetrapod species....Diabetic damage to eyes, heart, nerves, kidneys may be explained by controversial theory
...d-stage renal disease. Proponents of the theory argue that the primary cause of such tissue damage is a key compound in energy production other scientists long ago rejected as a contributor to diabetic side effects. The researchers address the many objections and questions raised by critics of their hyp...Government development policies, not communities, main threat to forest conservation projects
...will increase indefinitely. Those taking this view argue that only strict protection and exclusion of local people can prevent further environmental damage. Local groups, however, counter that community conservation has not been given a fair trial, because governments almost never devolve enough power or g...Biodiversity: measuring up to the loss
... of degradation of biodiversity. Butchart et al. argue that Red List Indices complement indicators based on population trends, because although the indices show coarser temporal resolution, they have much better geographic representation; they're based on nearly all species in a group worldwide rather th...Study in Royal Society journals presents evidence for inherited factors in homosexuality
...ly disappear from the population. The authors here argue genetic factors could partially explain male homosexuality, and propose a paradox solution: genetic factors favouring homosexuality in males could increase fecundity in females, recovering the loss of fitness. They suggest these factors should be par...... Northern Hemisphere. The authors of the new study argue that there are climate mechanisms involved that make warming climate conditions likely to lead to increased prevalence of drought in the western, interior region of North America. Looking at implications for the future, the authors express concern. ...
