DNA sequence of the human Y chromosome fully determined for first time

The first full sequence of the last human chromosome — the Y chromosome — to be assembled is complete, thanks to an international collaboration that includes Penn State researchers. The new sequence, which fills in gaps across more than 50% of the Y chromosome’s length, uncovers genomic features with implications for fertility, as well as cancer risk and severity.

Are egg cells in aging primates protected from mutations?

New mutations occur at increasing rates in the mitochondrial genomes of developing egg cells in aging rhesus monkeys, but the increases appear to plateau at a certain age and are not as large as those seen in non-reproductive cells, like muscle and liver.

Are egg cells in aging primates protected from mutations?

A new study shows that mutation frequencies in mitochondrial DNA are lower, and increase less with age, in the precursors of egg cells than in the cells of other tissues in a primate.

Unusual DNA folding increases the rates of mutations

DNA sequences that can fold into shapes other than the classic double helix tend to have higher mutation rates than other regions in the human genome. New research by a team of Penn State scientists shows that the elevated mutation rate in these sequences plays a major role in determining regional variation in mutation rates across the genome.

Could the bacteria in a child’s mouth predict obesity?

There may soon be a simple way to identify children at risk for developing obesity later in life. Researchers from Penn State University analyzed the bacteria in the mouths of 226 2-year-olds and found that a child's oral microbiota can be used as a tool to predict weight gain during the first two years of their life.

Your Child's Mouth Could Reveal Their Obesity Risk

Scientists believe the bacteria that live in a toddler’s mouth could provide clues as to whether they will become obese. Existing research suggests the microbes inhabiting the guts and mouths of obese adults differ to those without the condition, but less is known about this pattern in children. So biologists at Pennsylvania State University set out to investigate what a child’s microbiota could say about their weight.
