Malaria is almost under control in Suriname

Malaria is almost under control in Suriname. According to an impact study conducted by Hélène Hiwat - van Laar, who was awarded a PhD on the subject on 21 November at Wageningen University, a five-year control programme with new strategies has proved successful. The people most at risk nowadays are the mobile gold miner communities, especially those along the French Guianese border.

Ribosomes spontaneously change their form during protein production

Ribosomes, the construction sites for proteins, are far more complex than previously assumed. During the production of proteins they constantly and spontaneously change their form. This performance of eukaryotic ribosomes has now been demonstrated for the first time by scientists at Charité - Universitätsmedizin Berlin, the Max-Planck-Institut für Molekulare Genetik in Berlin, and Cornell University in New York, with the aid of special electron microscopic and biophysical methods.

B-type lamins are necessary for proper organ development

Scientists have long held theories about the importance of proteins called B-type lamins in the process of embryonic stem cells replicating and differentiating into different varieties of cells. New research from a team led by Carnegie's Yixian Zheng indicates that, counter to expectations, these B-type lamins are not necessary for stem cells to renew and develop, but are necessary for proper organ development.

Benefits of vitamin D-fortified yoghurt drink for people with diabetes

People with diabetes are known to have an increased risk of heart disease. New research published in BioMed Central's open access journal BMC Medicine shows that regular consumption of a vitamin D-fortified yoghurt drink improves cholesterol levels and biomarkers of endothelial dysfunction, a precursor of heart disease, in diabetics.

Dyslexic individuals have difficulties in excluding external noise

Dyslexia affects up to 17.5% of the population, but its cause remains somewhat unknown. A report published in the Nov. 23 issue of the online journal PLoS ONE supports the hypothesis that the symptoms of dyslexia, including difficulties in reading, are at least partly due to difficulty excluding excess background information like noise.

NIH-led study advances HIV vaccine research

HIV is coated in sugars that usually hide the virus from the immune system. Newly published research reveals how one broadly neutralizing HIV antibody actually uses part of the sugary cloak to help bind to the virus. The antibody binding site, called the V1/V2 region, represents a suitable HIV vaccine target, according to the scientists who conducted the study. In addition, their research reveals the detailed structure of the V1/V2 region, the last part of the virus surface to be visualized at the atomic level.

Scientists discover genetic mechanism behind finger malformation

Scientists from the EPFL and the University of Geneva have discovered a genetic mechanism that defines the shape of our members in which, surprisingly, genes play only a secondary role. The research published in Cell, online the 23rd of November, shows the mechanism is found in a DNA sequence that was thought, incorrectly, to play no role.

People eating out of home consume more calories and fat, less micronutrients

Eating out of home means you run a fair chance of ingesting more calories and fat, and less micronutrients like vitamin C, iron and calcium. And people nowadays eat more out of house, also in developing countries. So conclude scientists from the Antwerp Institute of Tropical Medicine, upon reviewing more than seven thousand studies. They report in the journal Obesity Reviews.

Uncommon genetic deletions associated with short stature

New research sifts through the entire genome of thousands of human subjects to look for genetic variation associated with height. The results of the study, published by Cell Press in the December issue of the American Journal of Human Genetics, suggest that uncommon genetic deletions are associated with short stature.
