Scientists explore how females shut off their second X chromosome

Posted by in categories: biological, genetics, sex

Researchers at the European Molecular Biology Laboratory (EMBL) in Heidelberg and Institut Curie in Paris have shown that the protein SPEN plays a crucial role in the process of X-chromosome inactivation, whereby female mammalian embryos silence gene expression on one of their two X chromosomes.

In their landmark research published in Nature on 5 February, the scientists reveal how SPEN targets and silences active on the X chromosome, providing important new insights into the molecular basis of X-inactivation.

In mammals, males and females differ genetically in their sex chromosomes—XX in females and XY in males. This leads to a potential imbalance, as more than a thousand genes on the X chromosome would be expressed in a double dose in females compared to males. To avoid this imbalance, which has been shown to lead to early embryonic lethality, female embryos shut down the expression of genes on one of their two X .

There’s a Cancer Treatment That Gives People ‘Night Vision’, And We Finally Know Why

Posted by in category: biotech/medical

Amongst all the different types of cancer treatment, photodynamic therapy — where light in is used to destroy malignant cells — might have one of the strangest side effects: patients are often better able to see in the dark.

Now researchers have figured out why this happens: rhodopsin, a light-sensitive protein in the retinas in our eyes, interacts with a photosensitive compound called chlorin e6, a crucial component of this type of cancer treatment.

The work builds on what scientists already know about the organic compound retinal, which is found in the eye and usually isn’t sensitive to infrared light.

This Exolung promises ‘unlimited’ air supply underwater

Posted by in category: futurism

The Exolung is aiming for the sweet spot between scuba and snorkeling by using the power of kicking legs to pull a steady supply of air down from the surface.

Boeing’s Starliner test flight had a 2nd critical software issue, NASA panel finds (report)

Posted by in category: space

Boeing is considering another test flight for its CST-100 Starliner commercial crew spacecraft amid concerns from a NASA safety panel about its first flight.

Boeing’s Starliner spacecraft launched on Dec. 20, but was unable to dock with the International Space Station as planned because it ended up in the wrong orbit. But of growing concern now are two software problems that were uncovered after the flight was complete.
