Checkered history of mother and daughter cells explains cell cycle differences
When mother and daughter cells are created each time a cell divides, they are not exactly alike. They have the same set of genes, but differ in the way they regulate them. view more (2009-10-20)
The human immune system may limit future evolution
Scientists from Imperial College London have suggested why the human genome may possess far fewer genes than previously estimated before the human genome project was begun. Research published in the July issue of Trends in Immunology, shows how a more advanced immune system in humans could explain why the human genome may have only a slightly... view more...

A new study of living cells could revolutionize the way we test drugs
Researchers have made a breakthrough by detecting the electrical equivalent of a living cell's last gasp. The work takes them a step closer to both seeing the 'heartbeat' of a living cell and a new way to test drugs. view more (2007-04-12)
Saved by junk DNA
VIB researchers linked to K.U.Leuven and Harvard University show that stretches of DNA previously believed to be useless 'junk' DNA play a vital role in the evolution of our genome. view more (2009-05-29)
Higher stress leads to longer life
Eating less may make you healthier: even more reason to start that diet tomorrow. Scientists at the Plymouth Marine Laboratory have found that eating less helps marine animals cope with pollution and other stressful situations, and may even let them live longer. Professor Michael Moore found that triggering a cellular process known as autophagy in... view more... (2004-03-26)
Lessons from yeast: A possible cure for Parkinson's disease?
Parkinson disease (PD) is a debilitating and lethal neurodegenerative disease, for which there is currently no cure. It is caused by the progressive loss of nerve cells that produce the chemical dopamine and is characterized by the accumulation of abnormal aggregates of a protein called alpha-syn in these dopaminergic nerve cells. view more (2008-08-15)
DNA replication behavior in complex organisms may foreshadow leaps in genomic discoveries
For the first time, findings by scientists at the Genome Institute of Singapore (GIS) may be paving the way for more efficient analyses and tests related to the replication of cells, and ultimately, to the better understanding of human biology, such as in stem cell research. view more (2007-08-16)
Improved statistical tools reveal many linked loci
An innovative new statistical method, described in the open-access journal PLoS Biology, streamlines the computation required to identify all the potential locations in the genome that influence a particular physical trait, or phenotype. view more (2005-07-26)
Let's Stick Together - A Protein Protects Chromosome Bonds
The protein Mnd2 inhibits premature separation of chromosomes during the formation of gametes. The now published discovery of this regulatory function may help to understand the origin of some common congenital chromosome defects. The project of a team of the University of Vienna funded by the Austrian Science Fund (FWF) contributes to the Campus... view more... (2005-03-29)
University of Kent researchers tackle hospital acquired infections
Researchers from the University of Kent and the University of Lille have been awarded European funding to study how yeasts such as Candida cause infections among hospital patients. Dr Fritz Mühlschlegel, Reader in Medical Microbiology in the Biosciences Department at Kent and Consultant Medical Microbiologist in the East Kent NHS Trust, and... view more... (2004-07-20)
Scripps research study reveals structural dynamics of single prion molecules
New techniques paint clearer picture of amyloid formation associated with protein-based inheritance and neurodegenerative diseases such as mad cow, Alzheimer's. view more (2007-02-13)
Biologists discover link between CGG repeats in DNA and neurological disorders
Researchers have long known that some repetitive DNA sequences can make human chromosomes "fragile," i.e. appearing constricted or even broken during cell divisions. view more (2009-01-12)
St. Jude finds link between cellular defense processes, showing how cancer cells survive
St. Jude Children's Research Hospital investigators have discovered that immune system cells that engulf and destroy germs in the body enlist help for this task from a common housekeeping mechanism that most cells use to keep their interiors healthy, a finding that is likely to help researchers understand how the body defends itself against... view more...

A rainbow of methods promises insights into biological processes and diseases
Physical alterations of DNA in chromosomes can cause serious diseases such as Down syndrome, Prader-Willi syndrome, or cancer. view more (2007-05-02)
Fungus Found in Humans Shown To Be Nimble in Mating Game
Brown University researchers have determined that Candida albicans, a human fungal pathogen, pursues both same-sex and the more conventional opposite-sex mating. The findings are published in the August 2009 edition of the journal Nature. view more (2009-08-13)
Better beer: college team creating anticancer brew
College students often spend their free time thinking about beer, but a group of Rice University students are taking it to the next level. They're using genetic engineering to create beer that contains resveratrol, a chemical in wine that's been shown to reduce cancer and heart disease in lab animals. view more (2008-10-17)
Researchers describe how cells take out the trash to prevent disease
Garbage collectors are important for removing trash; without them waste accumulates and can quickly become a health hazard. Similarly, individual cells that make up such biological organisms as humans also have sophisticated methods for managing waste. view more (2008-11-11)
Prediction of gene function in mammals
Gene function in mammals can be quickly and reliably predicted using a high-throughput analysis of patterns of RNA expression, according to an article published today in Journal of Biology. This challenges the conventional view that tissue-specificity is the best predictor of function, and could speed up the quest to understand whole genomes, in... view more... (2004-12-02)
Researchers find new taste in fruit flies: carbonated water
That fruit fly hovering over your kitchen counter may be attracted to more than the bananas that are going brown; it may also want a sip of your carbonated water. view more (2007-08-30)
New information about DNA repair mechanism could lead to better cancer drugs
Researchers at Washington University School of Medicine in St. Louis have shed new light on a process that fixes breaks in the genetic material of the body's cells. view more (2009-07-17)
