New technology could lead to the development of new cancer therapies DNA has an important job–it tells your cells which proteins to make. Now, a research team at the University of Delaware has developed technology to program strands of DNA into switches that turn proteins on and off. UD’s Wilfred Chen Group describes their results...

Scientists replay movie encoded in DNA
“Molecular Recorder” would reveal secrets of brain development. For the first time, a primitive movie has been encoded in — and then played back from — DNA in living cells. Scientists funded by the National Institutes of Health say it is a major step toward a “molecular recorder” that may someday make it possible to...

Laser Activated Gold Pyramids Could Deliver Drugs, DNA into Cells without Harm
The ability to deliver cargo like drugs or DNA into cells is essential for biological research and disease therapy but cell membranes are very good at defending their territory. Researchers have developed various methods to trick or force open the cell membrane but these methods are limited in the type of cargo they can deliver...

Sons of cocaine-using fathers have profound memory impairments
Fathers who use cocaine at the time of conceiving a child may be putting their sons at risk of learning disabilities and memory loss. The findings of the animal study were published online in Molecular Psychiatry by a team of researchers from the Perelman School of Medicine at the University of Pennsylvania. The researchers say the findings...

How to quickly identify sepsis-causing bacteria – melt it down
Stephanie Fraley (left) reviews bacterial DNA melt curve data with her graduate students(Credit: UCSD) When a patient is diagnosed with sepsis, a medical syndrome that kills more people than breast cancer, prostate cancer and HIV combined, it sets off a countdown for doctors to treat the infection and uncover the culprit causing the body’s systems to shut down....

How breaks in DNA are repaired
The results are significant for gene therapy procedures and for our understanding of cell transformation. A team of researchers from the biology department at TU Darmstadt has discovered that the processes for repairing DNA damage are far more complex than previously assumed. The ends of breaks in the double helix are not just joined, they...

Unexpected Risks Found In Replacing DNA To Prevent Inherited Disorders
The genes in mitochondria, which are the powerhouses in human cells, can cause fatal inherited disease. But replacing the bad genes may cause other health problems. Getty Images/Science Photo Library In September, reproductive endocrinologist John Zhang and his team at the New Hope Fertility Center in New York City captured the world’s attention when they announced...
