Today I learned
Today I learned that the space between the inner and outer nuclear membrane is called a perinuclear space, the name is pretty logical and I really shouldn’t be surprised by it, and yet, I still am.
Sure is nice how such simple things in this field of study are constantly bringing me surprise and excitement.
Good luck with your studies everyone!

Reverse Aging: How to Remove Wrinkles Inside Our Cells
Reverse Aging: How to Remove Wrinkles Inside Our Cells
A new study on how to reverse aging in our cells would enable medical professionals to treat or diagnose diabetes, fatty liver disease and other metabolic problems, and may even delay aging.
The investigation from the University of Virginia proposes that fatty liver and side effects of aging are additionally the consequences of our cells’ nucleus (the space containing our DNA) getting wrinkled.

Nuclear Membrane Repairs the ‘Dark Matter’ of DNA
Scientists have found a new function of the nuclear membrane, the envelope that encases and protects DNA in the nucleus of a cell – it fixes potentially fatal breaks in DNA strands.
Previously, the nuclear membrane was thought to be mostly just a protective bubble around the nuclear material, with pores acting as channels to transport molecules in and out. But in a study published on October 26 in Nature Cell Biology, a research team led by Irene Chiolo documents how broken strands of a portion of DNA known as heterochromatin are dragged to the nuclear membrane for repair.
Taehyun Ryu, Brett Spatola, Laetitia Delabaere, Katherine Bowlin, Hannah Hopp, Ryan Kunitake, Gary H. Karpen, Irene Chiolo. Heterochromatic breaks move to the nuclear periphery to continue recombinational repair. Nature Cell Biology, 2015; DOI: 10.1038/ncb3258
Composite illustration shows the location of heterochromatin in a chromosome (highlighted in pink and yellow, bottom left) and in a nucleus (red, top right). The blue-to-green line in the upper right-hand corner shows the path that a damaged section takes as it is dragged to the nuclear membrane (gray) for repair.Credit: Courtesy of Irene Chiolo
