Long lost sistersThe human race was divided into two separate groups within Africa for as much as half of its existence, says a Tel Aviv University mathematician. Climate change, reduction in populations and harsh conditions may have caused ... |
New study reveals hidden neotropical diversityEvidence of physically similar species hidden within plant tissues suggest that diversity of neotropical herbivorous insects may not simply be a function of plant architecture, but may also reflect the great age and area ... |
An ancient protein balances gene activity and silences foreign DNA in bacteriaCompared to humans, bacteria have a much tidier genome. The tiny microorganisms pack their genes closely together, and don’t carry around a lot of extraneous DNA, so-called junk DNA that fills in the gaps between genes. Some ... |
Researcher finds an SOS response to cancer-causing agentsUniversity of Saskatchewan microbiologist Wei Xiao has found a way to trigger a protein combination called 9-1-1 that sends an SOS signal for cells to fight cancer-causing agents such as industrial toxins, ultraviolet radiation, ... |
Researchers document rapid, dramatic 'reverse evolution' in the threespine stickleback fishEvolution is supposed to inch forward over eons, but sometimes, at least in the case of a little fish called the threespine stickleback, the process can go in relative warp-speed reverse, according to a study led by researchers ... |
Connecting cancer genesA large genetic study in mice has identified hundreds of genes involved in the development of cancer by examining the DNA of more than 500 lymphomas to find the cancer causing mutations. |
Plant biologists discover unexpected proteins affecting small RNAsNow that high school biology students can recite that genes are made of DNA, which is transcribed into messenger RNA (mRNA), which is then translated into protein, along comes a new class of molecules, sending students—and ... |
Immune cells kill foes by disrupting mitochondria 2 waysWhen killer T cells of the immune system encounter virus-infected or cancer cells, they unload a lethal mix of toxic proteins that trigger the target cells to self-destruct. A new study shows T cells can initiate cellular ... |
Researchers identify gene linked to vertebral defects in patient populationsMay 15, 2008 | pda version
Stowers Institute researchers Karen Staehling-Hampton, Ph.D., Managing Director of Molecular Biology, and Olivier Pourquié, Ph.D., Investigator, collaborated with colleagues from around the world to show that genes known ... |
Effect of mutant p53 stability on tumorigenesis and drug designIn the May 15th issue of G&D, Dr. Guillermina Lozano (MD Anderson Cancer Center) and colleagues reveal how the stabilization of a mutated form of p53 affects oncogenesis, and lends startling new insight into the potential ... |
Scientists are building database of bite marks(AP) -- It has sent innocent men to death row, given defense attorneys fits and splintered the scientific community. For a decade now, attorneys and even some forensic experts have ridiculed the use of bite marks to identify ... |
 Families Shed Light on Likely Causative Gene for Alzheimer'sThe genetic profile of two large Georgia families with high rates of late-onset Alzheimer's disease points to a gene that may cause the disease, researchers say. |
Mouse study: When it comes to living longer, it's better to go hungry than go runningA study investigating aging in mice has found that hormonal changes that occur when mice eat significantly less may help explain an already established phenomenon: a low calorie diet can extend the lifespan of rodents, a ... |
 Molecular 'clock' could predict risk for developing breast cancerMay 14, 2008 | pda version
A chemical reaction in genes that control breast cancer provides a molecular clock that could one day help researchers more accurately determine a woman’s risk for developing breast cancer and provide a new ... |
Genetic variation linked to sugary foodA new study released today in the online edition of Physiological Genomics finds that individuals with a specific genetic variation consistently consume more sugary foods. The study offers the first evidence of the role that ... |
