The recombination of chromosomes: a controlled game of love and chance?
Sexual reproduction has many advantages - some most pleasurable - and probably leads to the long-term survival of the species concerned. During the formation of reproductive cells or gametes, sexual reproduction is accompanied by an exchange of genes between the two chromosomes inherited from the parents. Each individual arising from these gametes... view more... (2002-10-22)
When cells go bad
When a cell's chromosomes lose their ends, the cell usually kills itself to stem the genetic damage. But University of Utah biologists discovered how those cells can evade suicide and start down the path to cancer. view more (2008-10-01)
Sesame seed extract and konjac gum may help ward off Salmonella and E. coli
A new study in SCI's Journal of the Science of Food and Agriculture shows that konjac gum and sesame seed extract may offer protection against different strains of E. coli and Salmonella bacteria. view more (2008-08-06)
Researchers uncover potential mechanisms to protect against genetic alterations, diseases
Peering into the DNA of tiny yeast, researchers at the Moores Cancer Center at the University of California, San Diego and the San Diego Branch of the Ludwig Institute for Cancer Research have pinpointed a large number of genes that can prevent a type of genetic rearrangement that may lead to cancer and other diseases. view more (2009-08-07)
Scripps scientists uncover mimicry at the molecular level that protects genome integrity
The new study, which was published on April 12, 2009, in an advanced online edition of the journal Nature Structural & Molecular Biology, draws new parallels between the Rad60 DNA repair factor and SUMO, a small ubiquitin-like modifier, which are both essential for maintaining genome stability during replication. view more (2009-04-14)
What's the difference between a human and a fruit fly?
Fruit flies are dramatically different from humans not in their number of genes, but in the number of protein interactions in their bodies, according to scientists who have developed a new way of estimating the total number of interactions between proteins in any organism. view more (2008-05-13)
Bacteria divide like clockwork
A team of researchers at MIT and the University of California at San Diego has shown how cell division in a type of bacteria known as cyanobacteria is controlled by the same kind of circadian rhythms that govern human sleep patterns. view more (2010-03-19)
Roles of DNA packaging protein revealed by Einstein scientists
Scientists at Albert Einstein College of Medicine of Yeshiva University have found that a class of chromatin proteins is crucial for maintaining the structure and function of chromosomes and the normal development of eukaryotic organisms. view more (2009-02-13)
'Insulator' helps silence genes in dormant herpes virus
By adulthood, most people have suffered at least one bout of painful cold sores brought on by the Herpes simplex virus 1, also known as HSV-1. view more (2007-05-03)
ETH Researchers Open New Perspectives for Biotechnology
Metabolic and biochemical reactions are basically the same in all living beings, or at least comparable. The genetic codes of all living beings, that is to say of bacteria, plants, fungii and animals, are made up of the same set of building blocks. Human genes are therefore correctly translated into the corresponding proteins even by bacteria. The... view more... (2002-11-28)
SIRT1 takes down tumors
Yuan et al. have identified another anti-cancer effect of the "longevity" protein SIRT1. By speeding the destruction of the tumor promoter c-Myc, SIRT1 curbs cell division. view more (2009-04-13)
Research milestone brings goal closer of cheap antimalarial drug for developing world
Researchers striving to create a less expensive version of a life-saving antimalarial drug, artemisinin, have cleared a major hurdle, according to a new report in the journal Nature. view more (2006-04-13)
Synthetic Biology Can Help Extend Anti-Malaria Drug Effectiveness
In addition to providing a simple and much less expensive means of making artemisinin, the most powerful anti-malaria drug in use today, synthetic biology can also help to extend the effectiveness of this drug. Fermenting artemisinin via engineered microbes, such as yeast, can be done at far lower costs than extracting the drug from Artemsisia... view more... (2009-03-09)
Displacing petroleum-derived butanol with plants
As a chemical for industrial processes, butanol is used in everything from brake fluid, to paint thinners, to plastics. According to a University of Illinois researcher, butanol made from plant material could displace butanol made from petroleum, just not at the fuel pump. view more (2009-01-09)
Scientists Clarify a Mechanism of Epigenetic Inheritance
Although letters representing the three billion pairs of molecules that form the "rungs" of the helical DNA "ladder" are routinely called the human "genetic code," the DNA they comprise transmits traits across generations in a variety of ways, not all of which depend on the sequence of letters in the code. view more (2008-04-23)
Little known DNA repair enzyme may be a tumor suppressor gene
The DNA in our cells is constantly being bombarded by environmental, chemical and cellular insults. Fortunately, our cells contain many enzymes devoted strictly to detecting and repairing any damage caused by these insults. view more (2006-01-04)
Sandia work launched on space shuttle shows live cells influence growth of nanostructures
Far above the heads of Earthlings, arrays of single-cell creatures are circling Earth in nanostructures. view more (2006-07-24)
Largest study of human 'interactome' reveals a novel way
Discoveries made during the first large-scale analysis of interactions between proteins in our cells hold promise for identifying new genes involved in genetic diseases. view more (2006-02-27)
Animal study identifies potential treatment for Huntington's disease
MassGeneral Institute for Neurodegererative Disorders (MIND) researchers have identified a compound that may lead to a treatment that could protect against the effects of Huntington's Disease (HD). view more (2007-10-09)
A new cellular pathway linked to cancer is identified by NYU researchers
In the life of a cell, the response to DNA damage determines whether the cell is fated to pause and repair itself, commit suicide, or grow uncontrollably, a route leading to cancer. view more (2008-07-25)
