RNA molecules are masters of their own destiny

Research suggests the products of transcription — RNA molecules — regulate their own production through a feedback loop. At any given moment in the human body, in about 30 trillion cells, DNA is being “read” into molecules of messenger RNA, the intermediary step between DNA and proteins, in a process […]

Antioxidants Vitamin C and Vitamin E Linked to Lower Risk of Parkinson’s

People who consume high levels of vitamin C and E in their diet may have a lower risk of Parkinson’s disease than people who get only small amounts of these nutrients, according to a new study from University of Milano-Bicocca, Italy, and Karolinska Institutet. The study was published in Neurology. […]

How an Embryo Tells Time

It is estimated that the majority of pregnancies that fail do so within the first seven days after fertilization, before the embryo implants into the uterus. In this time period, a complicated cascade of events occurs with precise timing. One particularly important process is called polarization, when the individual cells […]

Ginger Counters Certain Autoimmune Diseases in Mice

Naturopathic medicine, or herbal medicine, is all the rage, especially among young people. But how much of this is supported by science? Ginger is known to have anti-inflammatory and anti-oxidative effects, making it a popular herbal supplement to treat inflammatory diseases. And according to a Michigan Medicine led study published […]

DNA-editing method shows promise to treat mouse model of progeria

Researchers have successfully used a DNA-editing technique to extend the lifespan of mice with the genetic variation associated with progeria,  a rare genetic disease that causes extreme premature aging in children and can significantly shorten their life expectancy. The study was published in the journal Nature, and was a collaboration between the National Human Genome Research […]

Scientists capture the moving parts of the portal to the cell’s nucleus

The nucleus of a cell is well-shielded by a double membrane to protect its most sensitive possession—its DNA. Anything that enters or exits must pass through the nuclear pores, cylindrical structures made of hundreds of proteins. Scientists have made great advances in figuring out the architecture of the pore by reconstructing each […]
