Read moreHow Cells Tolerate DNA Damage – MDC Researchers Identify Start Signal for Cell Survival Program
Dr. Michael Stilmann, Dr. Michael Hinz and Professor Claus Scheidereit have shown that the protein PARP-1, which detects DNA damage within seconds, activates the transcription factor NF-kappaB, a well...
Life Sciences | Read moreResearch Reveals Lipid’s Unexpected Role in Triggering Death of Brain Cells
The work provides the first evidence that a lipid can initiate the suicidal, or apoptotic, response in cells. The findings involve a lipid called GM1-ganglioside. Lipids are fat-like molecules. GM1 bu...
Life Sciences | Read moreResearch reveals lipids' unexpected role in triggering death of brain cells
The lipid that accumulates in brain cells of individuals with an inherited enzyme disorder also drives the cell death that is a hallmark of the disease, according to new research led by St. Jude Child...

The war between the sexes has been fought on many fronts throughout time—from humans to birds to insects, the animal kingdom is replete with species involved in their own skirmishes. A recent ...
Life Sciences | Read moreResearcher discovers key to vital DNA, protein interaction
Adam Bogdanove, associate professor in plant pathology, was researching the molecular basis of bacterial diseases of rice when he and Matthew Moscou, a student in the bioinformatics and computation bi...
Life Sciences | Read moreInteractions with aerosols boost warming potential of some gases
Yet the complexity of nature -- and the models used to quantify it -- continues to serve up surprises. The most recent? Certain gases that cause warming are so closely linked with the production of ae...

"Our long-term study shows that El Niño, a global climate pattern, drives Sulfur butterfly migrations," said Robert Srygley, former Smithsonian post doctoral fellow who is now a research eco...
Life Sciences | Read moreForecasting solar-energy harvests
Most life on earth depends on the sun to provide the energy needed to sustain its function. For more than a billion years, photosynthesis—a mechanism that has evolved to perfection—has allowed plants ...
Power and Electrical Engineering | Read moreCHIP as a new target for thetreatment and prevention of muscular dystrophies
<p> Muscular dystrophies are a heterogenous group of inherited single-gene disorders, characterized clinically by progressive muscle weakness and wasting. In many cases the molecular basis of a ...
Technology Offerings | Read moreExperimental drug lets B cells live and lymphoma cells die
To function normally, the cells that make up bodily tissues must "decide" when to divide and multiply (proliferate) and when to die. Cell death restricts the human cell population as a count...
Life Sciences | Read moreTo regenerate muscle, cellular garbage men must become builders
For scientists at the European Molecular Biology Laboratory (EMBL) in Monterotondo, Italy, what seemed like a disappointing result turned out to be an important discovery. Their findings, publ...
