Genes involved in cell growth and cell division identified
A recent study shows that hundreds of genes contribute to cell growth and cell division. For the first time these genes, many of which are potential contributors to cancer, have been mapped in a single systematic study. view more (2006-02-23)
Flatworm genes may provide insights into human diseases, researchers say
Could vital information about many human diseases be deciphered from genes inside freshwater flatworms? A definitive yes is not the answer yet, but research at the University of Illinois at Urbana-Champaign has provided an important advance for pursuing both that idea and the biology of stem cells. view more (2005-12-14)
UCSD Study Shows Junk DNA Has Evolutionary Importance
Genetic material derisively called "junk" DNA because it does not contain the instructions for protein-coding genes and appears to have little or no function is actually critically important to an organism's evolutionary survival, according to a study conducted by a biologist at UCSD. view more (2005-10-20)
Animals can change genes quickly to keep up with viral ingenuity
Viruses are famous for evolving quickly, but the organisms they infect can't be expected to sit idly by. view more (2006-03-21)
microRNA-mediated metabolism
In the February 15th issue of G&D, Drs. Aurelio Teleman and Stephen Cohen (EMBL) assign one of the first biological functions to an animal microRNA: the microRNA miR-278 regulates energy homeostasis in Drosophila. view more (2006-02-15)
Cells, dyes and videotape: Online scientific methods journal incorporates multimedia
Observing the microscopic mysteries of embryos, cells, and chromosomes is feasible with advanced live imaging technologies. view more (2006-11-06)
Fruitfly study shows how evolution wings it
In the frantic world of fruitfly courtship, the difference between attracting a mate and going home alone may depend on having the right wing spots. view more (2006-04-20)
Tracing the formation of long-term memory
The formation of long-term memory in fruit flies can be demonstrated by the influx of calcium into cells called mushroom body neurons that occurs after special training that includes periods of rest, said researchers from Baylor College of Medicine (BCM) in a report that appears in the current issue of the journal Neuron. view more (2006-12-07)
MicroRNAs play a big part in gene regulation-and evolution
egulating when and where certain proteins are made is crucial to the normal functioning of living things. To make proteins, information from DNA is transcribed into RNA molecules and then translated into the amino acids building blocks of proteins. view more (2005-06-24)
More evidence mammals, fruit flies share make-up on function of biological clocks
A study by researchers at New York University and the University of London offers additional evidence that mammals and fruit flies share a common genetic makeup that determines the function of their internal biological clocks. The study appears in the latest issue of Current Biology. view more (2006-03-07)
Tracking the memory trace
Memory formation follows a dynamic pattern, allowing for retrieval from different areas of the brain, depending on when an organism needs to remember, said a researcher at Baylor College of Medicine. view more (2005-12-05)
Hard-wiring the fruit fly's visual system
Both vertebrate and fruit fly have so-called visual maps in the brain that represent the world they see. view more (2006-09-21)
Researchers provide study of early heart development and underlying cause of congenital heart defects
Congenital heart defects involve the malformation in one or more structures of the heart or blood vessels while the fetus is developing in the uterus. view more (2005-12-21)
Hunt for DNA amplified in cancers uncovers important target gene
Researchers at Harvard Medical School (HMS) and Massachusetts General Hospital (MGH) have discovered a new cancer-promoting role for a gene potentially involved in breast, liver, and other kinds of cancers. view more (2006-08-08)
Animal model of Parkinson's disease reveals striking sensitivity to common environmental toxins
In findings that support a relationship between agricultural chemicals and Parkinson's disease, two groups of researchers have found new evidence that loss of DJ-1, a gene known to be linked to inherited Parkinson's disease, leads to striking sensitivity to the herbicide paraquat and the insecticide rotenone. view more (2005-09-07)
Run amok enzyme causes same problems in both humans and fruit flies
An enzyme found at elevated levels in several human cancers has been linked to abnormal tumor growth in fruit flies, a discovery that provides a new model for understanding the link between stem cell biology and cancer, according to researchers at the University of Oregon. view more (2006-12-19)
Sperm proteome gives "tantalising glimpse" towards the origin of sex
The first ever catalogue of the different types of proteins found in sperm could help reveal the origins of sex and explain some of the mysteries of infertility, say scientists. view more (2006-11-13)
Evolutionary shifts in olfactory sensitivities in fruit flies
How do an animal's senses change as it evolves to occupy a new ecological niche? By comparing the olfactory system of the fruit fly Drosophila melanogaster, which feeds from multiple fruit types, with that of its sibling species D. sechellia, a specialist particularly drawn to a single fruit type. view more (2006-01-10)
FSU biologists uncover mechanisms that shape cells for better or worse
In a landmark study, biologists at Florida State University have uncovered a specific genetic and molecular mechanism that causes cell polarity - the asymmetric shape or composition critical to a cell's proper functioning. view more (2006-08-17)
RNAi and telomere length
A team of Russian scientists, led by Dr. Vladimir Gvozdev (Russian Academy of Sciences) reports on a novel link between RNAi and telomere maintenance in the Drosophila germline. view more (2006-02-01)
