## Brain Tissue

A team of researchers at the RIKEN Center for Biosystems Dynamics Research in Japan have developed a new way to keep brain tissue from animals alive and viable for up to 25 days. So far, scientists have been limited to carrying out experiments with brain tissue for only a couple of days, [according to *Science Alert*](<https://www.sciencealert.com/scientists-kept-mouse-brain-tissue-alive-for-weeks-on-a-special-membrane>).

"This method can be used for more than explanted tissues from animals," first author Nobutoshi Ota said in [a statement](<https://www.eurekalert.org/pub_releases/2019-10/r-btk100819.php>). "It will also improve research into \[the development of embryos\] through long-term culturing and observation which is necessary for growing tissue and organs."

## Fluid Dynamics

The researchers expanded on an already-existing technique that involves so-called microfluidic devices — a special and highly precise way to deliver the fluids and nutrients that brain tissue needs to stay alive.

A paper of their research [was published](<https://www.jstage.jst.go.jp/article/analsci/35/10/35_19P099/_article>) in the journal *Analytical Sciences* yesterday.

## Moisturize Me

A major hurdle: too much liquid would keep the tissue's cells from exchanging gases; too little, and it would dry out and die like an old sponge.

To solve the issue, the team developed a new microfluidic device that includes a permeable artificial membrane that allows some — but not all — liquid to pass through, keeping moisture levels just right.

## Author
I've been at Futurism since 2017, where my role has evolved to encompass design, writing, and increasingly editing. I've always been fascinated by space exploration and advanced transportation, which I've leaned into by interviewing luminaries in those fields while closely following the dimensions of policy and regulation that allow next-generation projects to succeed -- or, sometimes, to fail. I'm also keenly interested in the effects of generative AI on society, policies, and democratic institutions, as well as clean energy, physics and biology, and the vagaries of tech leadership. My work for Futurism has been cited by publications including Ars Technica, Gizmodo, PC Magazine, Jalopnik, Fox News, and the New York Post. I spent my childhood living in locations including Manila, the Philippines, and Geneva, Switzerland, attended McGill University, and now live in Toronto, Canada. Before Futurism I worked at AskMen and a small photography studio. In my free time, I'm an avid gardener, foodie, and craft beer lover, as well as a maker of artisanal hot pepper sauces. I have a magnificent dog named Freida.
