We understand that in the busy list of reddit, both your home page and popular, it's often hard to see a newly posted AMA you might be interested in. As a solution, we've set up a reddit-based program to message you when an AMA is posted. You can even select just the subject areas you are interested in! We won't have access to any of your personal information with this, it's a rather simple program that only works within reddit, so your anonymous account stays anonymous, and anytime you want to cancel the messages a simple 'stop' reply will stop them.

Science AMA Series: Beef without cows, sushi without fish, and milk without animals. We're cellular agriculture scientists, non-profit leaders, and entrepreneurs. AMA!


See the source article by following the link below:

We've gathered the foremost experts in the burgeoning field of cellular agriculture to answer your questions. Although unconventional, we've chosen to include leaders from cell ag non-profits (who fund and support researchers) as well as representatives from cutting edge cell ag companies (who both do research and aim to produce commercial products).

Given the massive cultural and economic disruption potential it made sense to also include experts with a more holistic view of the field than individual researchers. So while you're encouraged to ask details on the science, feel free to also field questions about where this small, but growing industry and field of study is going as a whole.

 

For a quick primer on what cellular agriculture is, and what it can do, check this out: http://ift.tt/2n202Yw

Bios:

Andrew Stout

Andrew became interested in cell ag in 2011, after reading a New York Times article on Mark Post’s hamburger plans. Since then, he has worked on culturing both meat and gelatin—the former with Dr. Post in Maastricht, NL, and the latter with Geltor, a startup based in San Francisco. Andrew is currently a New Harvest fellow, pursuing a PhD in Dr. David Kaplan’s lab at Tufts University. For his research, Andrew plans to focus on scalable, scaffold-mediated muscle progenitor cell expansion. Andrew holds a BS in Materials Science from Rice University.

 

Erin Kim

Erin has been working in cellular agriculture since 2014. As Communications Director for New Harvest, Erin works directly with the New Harvest Research Fellows and provides information and updates on the progress of their cellular agriculture research to donors, industry, the media, and the public. Prior to her role at New Harvest, Erin completed a J.D. in Environmental Law and got her start in the non-profit world working in legal advocacy.

 

Jess Krieger

Jess dedicated her life to in vitro meat research in 2010 after learning about the significant contribution of animal agriculture to climate change. Jess uses a tissue engineering strategy to grow pork containing vasculature and designs bioreactor systems that can support the growth of cultured meat. She was awarded a fellowship with New Harvest to complete her research in the summer of 2017 and is pursuing a PhD in biomedical sciences at Kent State University in Ohio. She has a B.S. in biology and a B.A. in psychology.

 

Kristopher Gasteratos

Kristopher Gasteratos is the Founder & President of the Cellular Agriculture Society (CAS), which is set for a worldwide release next month launching 15 programs for those interested to join and get involved. He conducted the first market research on cellular agriculture in 2015, as well as the first environmental analysis of cell-ag in August 2017.

 

Liz Specht, Ph.D. Senior Scientist, The Good Food Institute

Liz Specht is a Senior Scientist with the Good Food Institute, a nonprofit organization advancing plant-based and clean meat food technology. She has a bachelor’s in chemical engineering from Johns Hopkins University, a doctorate in biological sciences from UC San Diego, and postdoctoral research experience from University of Colorado. At GFI, she works with researchers, funding agencies, entrepreneurs, and venture capital firms to prioritize work that advances plant-based and clean meat research.

 

Saam Shahrokhi

Saam Shahrokhi became passionate about cellular agriculture during his first year of undergrad, when he learned about the detrimental environmental, resource management, and ethical issues associated with traditional animal agriculture. The positive implications of commercializing cellular agricultural products, particularly cultured/clean meat resonated strongly with his utilitarian, philosophical views. He studied Chemical Engineering and Materials Science at UC Berkeley, where co-founded the Cellular Agriculture Society, and he conducted breast cancer research at UCSF. Saam is now a researcher at Hampton Creek focusing on scaffolds and bioreactors for the production of clean meat.

 

Santiago Campuzano

Santiago Campuzano holds a BSc in Food science from the University of British Columbia. As a New Harvest research fellow and MSc student under Dr. Andrew Pelling, he wishes to apply his food science knowledge towards the development of plant based scaffold with meat-like characteristics.

 

Yuki Hanyu

Yuki Hanyu is the founder of Shojinmeat Project a DIY-bio cellular agriculture movement in Japan, and also the CEO of Integriculture Inc., the first startup to come out of Shojinmeat Project. Shojinmeat Project aims to bring down the cost of cellular agriculture to the level children can try one for summer science project and make it accessible to everyone, while Integriculture Inc. works on industrial scaling.

AAAS AMA: Hi, we’re Drs. Philippa Benson, Kip Hodges, and Warren Warren, the managing editor and deputy editors of Science Advances. Ask Us Anything!


See the source article by following the link below:

Hi Reddit! We're the editors for Science Advances, an open access journal that accepts longer research articles (up to 6,000 words). Since our launch in February of 2015, we’ve published more than 1,500 papers and have a number of articles with tens (and even hundreds) of thousands of downloads, and hundreds of citations. As we mature as a publication, we continue our interest in areas of great scientific breakthroughs and innovation on both broad and disciplinary-specific levels. The journal is broadly organized in the areas of life and biological sciences, earth and environmental sciences, and physical and materials sciences.

This month our publications range from water on the moon to the diverse interests of people who participated in the Women's March to the internal GPS of seabirds.

Feel free to ask us about what makes for a good research article, what topics we're interested in, what questions we find most intriguing, and anything about open access. We're also happy to chat about what makes us different and unique as an open access journal of AAAS, and what the editorial process here is like. We have editors Kip and Warren here to answer your questions as well as the managing editor Philippa Benson.

What do you want to know about publishing and open access?

We'll be back at 2 pm ET to answer your questions, Ask us anything!
