Hijacking Of Neural Crest Genes
In vertebrates, the peripheral nervous system and the craniofacial skeleton develop from a specific set of cells, known as neural crest cells. In this report, researchers in the laboratory of Dr. Marianne Bronner-Fraser at the California Institute of Technology have used the amphioxus genome sequence to investigate how this vertebrate-specific cell type evolved from an invertebrate ancestor.
Europe-Wide Investment In Lipid Research Will Help Tackle Disease, Says New Report
Leading scientists are calling for Europe to invest more funds into the study of lipids - the 'fatty' molecules that play a crucial role in the function of human cells and which are implicated in a range of diseases from obesity and diabetes to Alzheimer's.
Fossil Oak Galls Preserve Ancient Multitrophic Interactions
Galls are plant tissues whose development is caused by other organisms - particularly insects. The insects live and feed in the galls, and gall shapes indicate which kind of animal caused the gall to develop.
Test Of Bacteria Toxin Delivery System Could Pave Way For New Antibiotic Drugs
Researchers at the Hebrew University of Jerusalem have achieved a breakthrough in monitoring the toxin-delivery system of highly pathogenic bacteria - an accomplishment that could help pave the way for new drugs that will be capable of neutralizing those germs.
American Chemical Society Meeting In Philadelphia, Aug. 17-21
Mark your calendars for the 236th National Meeting and Exposition of the American Chemical Society (ACS), which will be held Aug. 17-21, 2008, in Philadelphia.The multi-disciplinary theme for this meeting is Chemistry for Health: Catalyzing Translational Research, with talks on drug discovery, drug delivery and drug testing.
Novel Evolutionary Tools For Studying Human Populations Using The X Chromosome
Research in the Department of Genetics at University of Leicester is well-known for its human population studies with the Y chromosome, including the relationship between the male surname and the Y chromosome, as well as a better understanding of the Viking settlement in the Northwest England.
Colonization Processes And The Maintenance Of Genetic Diversity: Insights From A Pioneer Rainforest Tree, Aucoumea Klaineana
Aucoumea klaineana, an endemic tree of Gabon rainforest, is the main forestry resource of the country. It only regenerates in open habitats, not in the forest. Extant trees represent founding individuals, surviving within the forest. Parentage analysis at a forest - savannah edge in which three different waves of regeneration had occurred, enabled to locate male and female parents of most individuals of the two younger generations.
Research On Octopuses Sheds Light On Memory
Research on octopuses has shed new light on how our brains store and recall memory, says Dr. Benny Hochner of the Department of Neurobiology at the Alexander Silberman Institute of Life Sciences at the Hebrew University of Jerusalem.
Inheritance Of L1014F And M918T Sodium Channel Mutations Associated With Pyrethroid Resistance In Myzus Persicae
Two mutations in the sodium channel gene confer resistance to pyrethroid insecticides in the peach - potato aphid, Myzus persicae. Pyrethroid - resistant and - susceptible M. persicae clones with various combinations of these mutations were crossed under laboratory conditions, and the genotypes of aphid progeny were analysed by direct DNA sequencing of the sodium channel gene.
EuroDYNA Leaves Healthy Genomic Research Ecosystem As Legacy
Europe's position as a major player in genome research has been boosted by the European Science Foundation's three-year EUROCORES programme EuroDYNA. As it draws to a close, EuroDYNA (Dynamic Nuclear Architecture and Chromatin Function) is leaving behind a healthy European ecosystem of interacting multidisciplinary research projects focused on the structure of the cellular nucleus and mechanisms governing gene expression.
