Thinking ahead: Bacteria anticipate coming changes in their environment
A new study by Princeton University researchers shows for the first time that bacteria don't just react to changes in their surroundings -- they anticipate and prepare for them. The findings, reported in the June 6 issue of Science, challenge the prevailing notion that only organisms with complex nervous systems have this ability. view more (2008-06-19)
Genes that protect against atherosclerosis identified
One way of combating atherosclerosis is to reduce levels of "bad cholesterol" in the blood. Scientists at the Swedish medical university Karolinska Institutet have now identified the genes that bring about this beneficial effect. view more (2008-03-14)
Genome of saltwater creature could aid understanding of gene grouping
The genetic code of a simple saltwater creature could help researchers learn more about how groups of genes function in humans and other species. view more (2008-08-21)
New gene silencing therapy for cervical cancer
Researchers at The University of Queensland's (UQ) Centre for Immunology and Cancer Research (CICR), based at the Princess Alexandra Hospital, have pioneered a new approach for the treatment of cervical cancer. view more (2005-11-17)
Assembling the jigsaw puzzle of drug addiction
Using an integrative meta-analysis approach, researchers from the Center for Bioinformatics at Peking University in Beijing have assembled the most comprehensive gene atlas underlying drug addiction and identified five molecular pathways common to four different addictive drugs. view more (2008-01-07)
Studies elucidate genetic links between cancer and schizophrenia
A series of studies presented today at the American College of Neuropsychopharmacology (ACNP) annual meeting elucidates evidence that there is a genetic link between schizophrenia and cancer, providing a surprising possible scientific explanation for lower rates of cancer among patients with schizophrenia - despite having poor diets and high rates... view more...

World's first "robot scientist" proves a major success in the lab
A "robot scientist" that generates hypotheses about the function of particular genes in baker's yeast - and then designs and carries out experiments to test them - has been developed by a team of British scientists, according to new research published in the journal Nature today [15 January 2004]. "This research is very exciting as we have given... view more... (2004-01-12)
Interaction between gene variants may alter brain function in schizophrenia
A collaborative study led by investigators from Massachusetts General Hospital (MGH) is giving what may be the first look at how interactions between genes underlie a key symptom of schizophrenia, impaired working memory. view more (2008-11-10)
Wake up and smell the sweat
Some people are oblivious to the odor in the locker room after a game, while others wrinkle their noses at the slightest whiff of sweat. view more (2007-11-26)
Researchers discover how infectious bacteria can switch species
Scientists from the Universities of Bath and Exeter have developed a rapid new way of checking for toxic genes in disease-causing bacteria which infect insects and humans. view more (2008-10-09)
Human induced plurtipotent stem cells reprogrammed into germ cell precursors
For the first time, UCLA researchers have reprogrammed human induced pluripotent stem (iPS) cells into the cells that eventually become eggs and sperm, possibly opening the door for new treatments for infertility using patient-specific cells. view more (2009-01-27)
Indiana U researchers closer to finding a genetic cause of hearing loss in aging
Researchers at Indiana University School of Medicine have taken a step toward understanding the genetics that make people more susceptible to the loss of hearing as they age. view more (2006-05-17)
The evolutionary foundation of genomic imprinting in lower vertebrates
A Chinese scientist group working in College of Life Science, Zhejiang University, has shown that, as mammalian Igf2 CpG island, goldfish Igf2 CpG island has a parental differentially methylated region (DMR). view more (2009-05-18)

Prion discovery gives clue to control of mass gene expression
The discovery in common brewer's yeast of a new, infectious, misfolded protein -- or prion -- by University of Illinois at Chicago molecular biologists raises new questions about the roles played by these curious molecules, often associated with degenerative brain diseases like "mad cow" and its human counterpart, Creutzfeldt-Jakob. view more (2009-03-16)
New study shows how genes control blood proteins important to health
A new study shows how genes control levels of many blood proteins implicated in disease. The findings are the result of an international collaboration between scientists at the University of Exeter, the National Institute on Aging, and the Tuscany and Florence Health Agencies. view more (2008-05-09)
Nature press release on DiGeorge syndrome paper
[410097] LIFELINES: CATCH 22 (pp97–101) In the 1 March issue of Nature, researchers from Baylor College of Medicine in Texas pinpoint the gene behind one of the most common genetic diseases to affect humans: DiGeorge syndrome. The disease results in a broad spectrum of symptoms, including heart abnormalities, disruption of the immune system... view more... (2001-02-23)
Genes that both extend life and protect against cancer identified
A person is 100 times more likely to get cancer at age 65 than at age 35. But new research reported today in the journal "Nature Genetics" identifies naturally occurring processes that allow many genes to both slow aging and protect against cancer in the much-studied C. elegans roundworm. view more (2007-10-15)
What makes a fungus virulent? It's lipase
Infection with the fungus Candida parapsilosis is a major problem for individuals in intensive care units, as well as for premature infants and immunocompromised adults. Despite this, little is known about which of its genes account for its virulence. view more (2007-09-14)
Gene exchange common among sex-manipulating bacteria
Certain bacteria have learned to manipulate the proportion of females and males in insect populations. Now Uppsala University researchers have mapped the entire genome of a bacterium that infects a close relative of the fruit fly. view more (2009-03-26)
