Death, Division Or Cancer? Newly Discovered Checkpoint Process Holds The Line In Cell Division
Each day, a staggering number of cells perform a feat that still amazes researchers with its complexity: they divide to produce perfect replicas of each other. The process is called...
DNA vaccination for avian flu created
PHILADELPHIA, July 3 (UPI) -- U.S. scientists say they've developed a potential way to use DNA to vaccinate against avian flu, allowing rapid mobilization during an epidemic.
Disease-detecting Lab In The Palm Of Your Hand
Detecting food-borne diseases such as campylobacter and salmonella long before they enter the food chain would help ensure that the dinner on your table is safe to eat. There is...
Evolutionary Origin Of Mammalian Gene Regulation Is Over 150 Million Years Old
Scientists have found that a complex, highly conserved and extremely important mechanism of controlling genes is over 150 million years old. The findings have provided new insights into the evolution...
Fungi The Cause Of Many Outbreaks Of Disease, But Mostly Ignored
Many people, scientists among them, are largely unaware of the roles fungi play in the world around us. Research on fungi and fungal diseases are seriously neglected as a result...
Ethanol byproduct produces green results
Commercial flower and plant growers know all too well that invasive, ubiquitous weeds cause trouble by lowering the value and deterring healthy growth of potted ornamental plants. To control weeds,...
Penguin Chicks Frozen by Global Warming?
Young penguins are freezing to death as rainfall increases in Antarctica—one of many factors endangering two-thirds of penguin species, a new paper says.
Life-extending Protein Can Also Have Damaging Effects On Brain Cells
Proteins widely believed to protect against aging can actually cause oxidative damage in mammalian brain cells, according to a new report in Cell Metabolism. The findings suggest that the proteins...
New technique produces genetically identical stem cells
Adult cells of mice created from genetically reprogrammed cells—so-called induced pluripotent stem (IPS) stem cells—can be triggered via drug to enter an embryonic-stem-cell-like state, without the need for further genetic...
Giraffe Helps Camels, Zebras Escape from Circus
Circus animals escape from Dutch circus with aide of giraffe.
Moldy cave art prompts access debate
The Lascaux cave drawings in France have survived for 17,000 years but are now endangered by encroaching black mold spots, the latest in a series of threats unwittingly brought in...
High Hormone Levels in Seabird Chicks Prepare Them to Kill Their Siblings
The Nazca booby, a Galapagos Island seabird, emerges from its shell ready to kill its brother or sister. Wake Forest University biologists and their colleagues have linked the murderous...
Genomics Research Focuses on Rice Variety Improvement
Crop varieties can be improved through the study of genomics without creating genetically transformed varieties. That is the mission of a multistate research project led by the University of Arkansas...
