New insights into neural tube defects
Environmental and genetic factors lead to neural tube defects in 1 in every 1,000 births and cause 1 in 20 of every spontaneous abortion. One cause of these defects is the failure of cells within the neural tube to migrate to the middle of the developing neural tube. view more (2006-01-12)
UNMC researchers help make diagnostic breakthrough with Burkitt lymphoma; study detailed in New England Journal of Medicine
An international research study involving the University of Nebraska Medical Center, the National Cancer Institute and 10 other institutions has successfully identified the gene expression signature for Burkitt lymphoma. view more (2006-06-12)
Scientists identify molecular structure of key viral protein
Scientists at Northwestern University have determined the molecular structure of a viral protein, the parainfluenza virus 5 fusion (F) protein. view more (2006-01-05)
A clearer view on biology
The European Molecular Biology Laboratory [EMBL] has developed a new computational tool that makes images obtained with cutting-edge microscopes even sharper. view more (2007-03-06)
UF scientists discover evolutionary origin of fins, limbs
Evolutionarily speaking, the genetic instructions used to construct and position our limbs were being perfected more than half a billion years ago in fishes, not along the sides of the body where the fins that preceded human arms and legs sprouted, but at the midline that runs along the backbone and belly. view more (2006-07-27)
Structure of key cancer drug target identified
Researchers from Monash's Department of Biochemistry and Molecular Biology have determined the structure of the protein JAK2 kinase, a discovery with huge implications for the design and development of new cancer drugs. view more (2005-10-26)
New treatment option breaks Leukemia's resistance to chemotherapy, radiation therapy
German researchers set out to outwit cancer tumor cells that have become resistant to chemotherapy or radiation therapy and ended up expanding therapeutic applications of radionuclides in fighting leukemia. view more (2006-06-05)
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)
Plague agent helps UT Southwestern researchers find novel signaling system in cells
The bacterium that causes bubonic plague would seem unlikely to help medical scientists, but researchers at UT Southwestern Medical Center have harnessed it to uncover a new regulatory mechanism that inhibits the immune system. view more (2006-05-26)
rotein folding: Building a strong foundation
Like a 1950's Detroit automaker, it appears that nature prefers to build its proteins around a solid, sturdy chassis. view more (2006-09-18)
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)
New compound stops brain cell degeneration in Alzheimer's disease
Drug discovery researchers at Northwestern University have developed a novel orally administered compound specifically targeted to suppress brain cell inflammation and neuron loss associated with Alzheimer's disease. view more (2006-01-20)
Brains of Britain
Two young people are set to represent Britain in, not one school science Olympiad, but two! This is equivalent to an international athlete running in the hundred metres and then throwing the javelin. Erica Thompson, from the Douglas Academy in Glasgow and David Wyatt from Winchester College are representing their country at the International... view more... (2002-05-08)
Anti-inflammatory effects of omega 3 fatty acid in fish oil linked to lowering of prostaglandin
Omega 3 fatty acids in dietary fish oil are reported to have anti-inflammatory and anti-thrombogenic and anti-arrhythmic effects in humans, but the biochemical basis for these beneficial health effects is not well understood. view more (2006-04-04)
Atherosclerosis studied at the cellular level
A McMaster University study on atherosclerosis will be featured on the cover of the December issue of the high impact American Heart Association scientific journal, Arteriosclerosis, Thrombosis and Vascular Biology. view more (2005-12-02)
Clawed frog helps Fanconi anemia research make leaps
A large, clawed frog is helping Oregon Health & Science University researchers gather a princely sum of knowledge on Fanconi anemia, a rare, genetic, cancer-susceptibility syndrome. view more (2006-01-25)
A clue to core problem of neurodegenerative disease and cell death
Misfolded and damaged proteins are common to all human neurodegenerative diseases. Clumps of these aggregated proteins destroy neurons within the brain and cause disease. view more (2006-02-10)
NYU biologists map out early stages of embryo formation
A team of genomic researchers headed by biologists at New York University's Center for Comparative Functional Genomics, in collaboration with researchers at Harvard University, the Max Planck Institute, and Cenix Biosciences, has mapped out a preliminary molecular diagram of the early stages of embryo formation, offering for the first time a... view more...

Novel molecular 'signature' marks DNA of embryonic stem cells
A team of scientists announced today a critical step on the path of realizing the promise of embryonic stem (ES) cells for medicine. view more (2006-04-21)
University of Iowa scientists explore function of 'junk DNA'
University of Iowa scientists have made a discovery that broadens understanding of a rapidly developing area of biology known as functional genomics and sheds more light on the mysterious, so-called "junk DNA" that makes up the majority of the human genome. view more (2006-11-14)
