Study shows how epigenetic memory is passed across generations

A growing body of evidence suggests that environmental stresses can cause changes in gene expression that are transmitted from parents to their offspring, making "epigenetics" a hot topic. Epigenetic modifications do not ...

Carcinogenic mechanism of incomplete cell reprogramming in vivo

A research team led by the group of Professor Yasuhiro Yamada, Center for iPS Cell Research and Application (CiRA), Kyoto University, has discovered that when cells are subjected to incomplete reprogramming in vivo, epigenetic ...

New application of physics tools used in biology

A Lawrence Livermore National Laboratory physicist and his colleagues have found a new application for the tools and mathematics typically used in physics to help solve problems in biology.

Controlling genes with light

Although human cells have an estimated 20,000 genes, only a fraction of those are turned on at any given time, depending on the cell's needs—which can change by the minute or hour. To find out what those genes are doing, ...

Dual systems key to keeping chromosomes intact

USC scientists have discovered how two different structural apparatuses collaborate to protect repetitive DNA when it is at its most vulnerable – while it is being unzipped for replication.

Ancient DNA holds clues to climate change adaptation

(PhysOrg.com) -- Thirty-thousand-year-old bison bones discovered in permafrost at a Canadian goldmine are helping scientists unravel the mystery about how animals adapt to rapid environmental change.
