Inside what look like oversized ziplock bags strewn with tubes of blood and fluid, eight fetal lambs continued to develop — much like they would have inside their mothers. Over four weeks, their lungs and brains grew, they sprouted wool, opened their eyes, wriggled around, and learned to swallow, according to a new study that takes the first step toward an artificial womb. One day, this device could help to bring premature human babies to term outside the uterus — but right now, it has only been tested on sheep.

It’s appealing to imagine a world where artificial wombs grow babies, eliminating the health risk of pregnancy. But it’s important not to get ahead of the data, says Alan Flake, fetal surgeon at the Children’s Hospital of Philadelphia and lead author of today’s study. “It’s complete science fiction to think that you can take an embryo and get it through the early developmental process and put it on our machine without the mother being the critical element there,” he says.

Instead, the point of developing an external womb — which his team calls the Biobag — is to give infants born months too early a more natural, uterus-like environment to continue developing in, Flake says.

Quercetin may be able to influence apoE and could be a potential therapeutic for Alzheimer’s disease.


The Apolipoprotein E connection

The most common type of dementia is Alzheimer’s disease and as the average life expectancy has risen in recent decades so has the occurrence of this and other neurodegenerative diseases. Aging is the primary risk factor for Alzheimer’s and researchers are searching for new ways to combat this devastating disease.

The pathology of Alzheimer’s is characterized by the formation of tau-tangles and the accumulation of amyloid-β (Aβ) which damage neurons and gradually destroy sections of the brain leading to death. The debate over which is primary, tau or amyloid is ongoing and it remains unclear which is the most important of the two, or if both are a consequence of another underlying process.

The Middle East has an outsize impact on energy here on Earth. One analyst thinks some regional powerhouses may leverage that role into the development of natural resources in space.

Countries like the United Arab Emirates and Saudi Arabia are developing space programs and investing in nascent private space commodity initiatives, said Tom James, a partner at energy consultant Navitas Resources. Doing so could give them a foothold in building extraterrestrial reserves of water — a substance likely to fuel travel within space — and other resources that could be used for in-space manufacturing.
