Biochemists discover new insights into what may go awry in brains of Alzheimer’s patients

August 22, 2019 dna 0
Three decades of research on Alzheimer’s disease have not produced major treatment advances for patients. Researchers now report new insights that may lead to progress in fighting the devastating disease. They discovered beta amyloid has a specific amino acid that can form a kink, like a kink in a garden hose, creating a harmful molecular zipper and leading to the death of neurons.

Pluripotency: ‘Butterfly effect’ discovered

August 22, 2019 dna 0
Pluripotent cells can give rise to all cells of the body, a power that researchers are eager to control because it opens the door to regenerative medicine and organ culture for transplants. But pluripotency is still a black box for science, controlled by unknown genetic and epigenetic signals. Researchers have now uncovered one of those epigenetic signals, after a detective quest that started almost a decade ago.

Slow electrons to combat cancer

August 22, 2019 dna 0
Slow electons can be used to destroy cancer cells – but how exactly this happens has not been well understood. Now scientists have been able to demonstrate that a previously little-observed effect actually plays a pivotal role: Due to a process called interatomic Coulombic decay, an ion can pass on additional energy to surrounding atoms. This frees a huge number of electrons, with precisely the right amount of energy to cause optimal damage to the DNA of the cancer cells.
