  • Genetic Variants In Autoimmunity
    Scientists report new genetic associations to four diseases in a large scale collaborative effort.
  • New AIDS Risk Factor
    More rapid HIV disease progression occurs in individuals who have a specific genetic risk factor.
  • Genetic Variation In Hair, Eye, And Skin Pigmentation
    Several new genetic associations for human hair, eye and skin pigmentation in individuals of European ancestry are reported.
  • Genetic Risk Factor For Colorectal Cancer
    Common variants in the gene SMAD7 are associated with an increased risk of colorectal cancer.
  • Host Of New Genes Spotted
    Scientists have uncovered a complex network of genes involved in the conversion of normal cells to cancerous ones.
  • The Future's Bright
    Researchers have now linked the tendency for future optimism to activity in a small network of areas in the brain.
  • Old Trick, New Dog
    A new model of anti-viral response in mammals is presented.
  • Gene Essential To Sperm Production Identified
    In a study published online, researchers report the identification of a gene that has a key role in the development of sperm.
  • Rise And Shine
    Researchers have established a causal link between the activity of a particular group of brain cells and transitions between sleep and wakefulness.
  • Genes Tell Our Evolutionary Tale
    Geneticists have identified a number of genes, for a variety of functions, that show the hallmarks of having been favoured by natural selection in different populations.
  • The Brain And Feeding
    The activity of several brain areas governing human feeding behaviour is modulated by levels of a single gut hormone in the blood.
  • Single-Gene 'Badge' For Stem Cells
    Geneticists studying the cells of the human gut have found a gene that seems to be expressed exclusively in mouse adult stem cells of the small intestine and colon

  • The Beat Goes On With AKAP18
    A protein, known as AKAP18, could help the heart to beat faster in response to adrenaline or noradrenaline.
  • Heart Of The Matter
    Researchers have developed a strategy to successfully manipulate stem cells into becoming heart muscle cells.
  • The Long And The Short Of Fatty Liver
    Study reports that not all types of fat are equally harmful.
  • Micro-Managing HIV Replication
    Cellular microRNAs could help HIV persist by shutting off viral replication and contributing to latency.
  • HIV Stuns Immune Cells
    A known suppression factor in the immune system increases in HIV-infected individuals on critical immune cells.
  • Fountain Of Youth
    Researchers have identified the cells that provide an essential survival factor to newly created immune cells.
  • The Gene-Mapper's Best Friend
    Genetic variants associated with dominant or recessive disease-related traits in dogs can be mapped efficiently and with high confidence.
  • NO End To Protein Modification
    A new biological signalling molecule is described.
  • Mitochondrial Downfall In Parkinson's Disease
    The mutation of two genes associated with the development of Parkinson's disease cooperate to regulate mitochondrial function when cells are stressed.
  • Effective Gene Silencing
    New research shows that small interfering RNAs (siRNAs) can be effective and safe tools for silencing genes in vivo.
  • MicroRNAs And Metastasis
    A particular microRNA, microRNA-10b (miR-10b), has been found in abundance in breast cancer cells that have the ability to spread to other organs.
  • Identifying Self Renewing Cells
    Large numbers of adult stem cells can be efficiently obtained from testis, thanks to a newly identified molecule on the cell surface that will allow researchers to tell them apart from non-self-renewing cell types.
