Science Hello, I’m Dr Sara Fontani from the University of Wolverhampton in the United Kingdom and I’m a primatologist. I’m here to talk about captive lemur’s welfare, reproduction and conservation. Please ask me anything!


Hi Reddit, I’m a Marie Curie Postdoctoral Research Fellow at Wolverhampton University, where I’m a member of the Animal Behaviour & Wildlife Conservation group, working on the Marie Curie project The Enriched Primate - EnPrim.

My project focuses on the critically endangered Gentle lemur (Hapalemur alaotrensis) and aims to enhance the breeding success and welfare of captive lemurs using chemical communication to promote mating behaviours and increase reproduction in captivity. My research involves strictly non- invasive methods to obtain chemical, behavioural, endocrinological and microbiological data and it will contribute to the preservation of a species at very high risk of extinction with possible reintroduction into the natural environment.

If you are interested in talking about my research or just or just want to learn more about these wonderful animals, I will be on at 2pm (GMT 1) on Saturday 1st October, ask me anything!

Proof: Here's my proof!

Thank you for spending this time with me and for your interest in my project and these beautiful primates. I did not expect so many fascinating questions, it has been great to see so much interest! I am sorry I did not manage to answer all the questions, but I have got time constraints due to other commitments. If you want, you can contact me at [email protected] and follow me on Twitter at @SaraFirenze. I will be happy to address to any other question. Please do not forget to leave your feedback at https://www.menti.com/alsm1ao6jy3h/0 All the very best!

Science Hi, I am Tyler Horvath and I discovered that caves on the Moon are the most habitable places (thermally) in the solar system. Ask me anything!


I am Tyler Horvath, a PhD student studying Planetary Science at UCLA and I am the main researcher who discovered that caves on the Moon have some of the most habitable temperatures in the solar system. I have worked on multiple NASA missions as a satellite operator and as a scientist, but primarily I have been a part of the Lunar Reconnaissance Orbiter Diviner Lunar Radiometer Science Team. Other missions I have worked on in one way or another has been:

Science: Lunar Reconnaissance Orbiter (Diviner Lunar Radiometer) The Mars Perserverence Rover (RIMFAX) NASA CLPS-19 (L-CIRiS: Lunar Compact Infrared Imaging System) Moon Diver (Proposed Lunar Rover) TESS (Transiting Exoplanet Survey Satellite)

Operations and science: Kepler Space Telescope

Operations: MMS (Magnetospheric Multiscale Mission)

I primarily study the Moon and Mars though I am familiar with many topics related to planetary science and astronomy. Ask me anything about my research or space!

EDIT: I will be periodically checking the comments but will continue to answer any questions throughout the day, I appreciate all of the cool questions people have asked so far :)

EDIT 2: I realized I had put TESS under operations and science, I have only done science with the particular mission. All of the questions have been great, keep them coming! :)

EDIT 3: Logging off for the night. I'm happy to keep answering questions tomorrow though! Thanks for all of the great space questions, hope I was able to help you learn some cool things!

EDIT 4: I think I'm going to end this AMA here, there were so many awesome questions that people asked and I had a blast. If you're reading this and still have a question, it was probably answered in a comment. If it wasnt, feel free to message me on here and I will try to get back to you with an answer!!

Have a good one, Tyler

Science IAMA Climate Scientist who studies ideas to directly cool the planet to reduce the risks of climate change, known as solar geoengineering, and I think they might actually be used. Ask me anything.


Hi, I'm Pete Irvine, PhD (UCL) and I'm here to answer any questions you might have about solar geoengineering and climate change.

I've been studying solar geoengineering for over a decade and I believe that if used wisely it has the potential to greatly reduce the risks of climate change. Given the slow progress on emissions cuts and the growing impacts of climate change, I think this is an idea that might actually be developed and deployed in the coming decades.

I've published over 30 articles on solar geoengineering, including:

  • A fairly accessible overview of the science of solar geoengineering.
  • A study where we show it would reduce most climate changes in most places, worsening some climate changes in only a tiny fraction of places.
  • A comment where we argue that it could reduce overall climate risks substantially and *might* reduce overall climate risks in ALL regions.

I'm also a co-host of the Challenging Climate podcast where we interview leading climate experts and others about the climate problem. We've had sci-fi author Neal Stephenson, Pulitzer prize winner Elizabeth Kolbert, and climate scientist Prof. Gavin Schmidt.

Ask Me Anything. I'll be around today from 12:45 PM Eastern to 3 PM Eastern.

Proof: Here you go.

EDIT: Right, that was fun. Thanks for the great questions!

EDIT2: Looks like this grew a bit since I left. Here's a couple of videos for those who want to know more:

  • Here's a video where I give a ~30 minute overview of solar geoengineering
  • And, Here's a video where I debate solar geoengineering with the former spokesperson for Extinction Rebellion.

EDIT3: Looks like this is still growing, so I'm going to answer some more questions for the next hour or so, that's up to 13:30 Eastern 15th July. Oops, I forgot I have a doctor's appointment. Will check back later.

I've also just put together a substack where I'll put out some accessible articles on the topic.

Science I am Stan Kim, the CEO of WinSanTor, a patient owned pharma start-up. We are developing a drug that is clinically regrowing peripheral nerves! We're working on bringing it to market. Ask me anything.


Hi Everyone! Awhile back we did an AMA about some of our drug research that found a drug that could potentially reverse peripheral neuropathy.

This is an update to that AMA. I'll share a little bit about where our research is currently and our ultimate goal now: to bring a drug we have clinically proven to regrow peripheral nerves to market.

Since our last AMA we've done more clinical research with human subjects and found our drug is being tested for safety and efficacy to treat neuropathy. Neuropathy is a condition where the nerves in your extremities die off. It's a condition that can affect people with diabetes, those undergoing cancer treatment or cancer survivors, HIV patients, scores of others. Neuropathy is a condition that affects hundreds of millions of people with varying causes. We believe our drug can make a substantial difference in their quality of life.

We are the first company to show regrowth of peripheral nerves in a clinical setting. This was a huge milestone for us. And our next step is to bring the drug to market. One of the issues with the pharmaceutical industry involves new companies being bought out merely to have their intellectual property shelved. We feel strongly that this drug could be life changing to millions and there's not really enough money to allow us to sleep at night if that happened.

Ask us anything about our drug, our studies, or what it takes to get a drug to market.

I'm Stan Kim, the CEO of WinSanTor and I'm here with a staff scientist to answer your questions.


Thanks for the great questions everyone! That's all the time I have for today. I'll try and pop back in to answer more questions later if I can.

I got a few inquiries about investor opportunities and how to join our future studies. Feel free to reach out to me at [email protected].

In August of 2020 I joined Reddit to discuss cancer immunotherapy and the details of our head and neck cancer clinical trial for Multikine. Our mission at CEL-SCI is to improve the treatment of cancer and other diseases by utilizing the immune system; the body’s natural defense system.

In the time since my last AMA, research in cancer immunotherapy has continued to make great strides and so has CEL-SCI. Our team has recently returned from ASCO 2022 where over 40,000 oncology professionals from around the world attended the largest annual conference focused on global cancer care.

2,500 abstract presentations of cutting-edge research were presented with one of those being from our Chief Scientific Officer, Eyal Talor, Ph.D.

Today I am here to answer questions regarding our abstracts published at ASCO, the evolution of cancer immunotherapy and the ever-changing landscape of cancer treatment.

You can learn more about CEL-SCI on our website: CEL-SCI.com

Science I am Jason Burford, the formulation chemist for Landrace Bioscience. I make your favorite cannabinoids water-soluble and tasty. Ask me anything!


Hi there,

I’m Jason Burford, a chemist and formulator who works at Landrace Bioscience in Chattanooga, Tennessee. As a chemist, I’ve developed protocols for separation of cannabinoids via HPLC, and when we pivoted our business, I began my work as a formulator making cannabis-infused topicals and beverages. What separates me from the competition is that I use our patented “SENDS” technology to solubilize cannabinoids without the aid of machinery, such as a microfluidizer or ultrasonic homogenizer. This allows for ease of use for me and my customer as well, since we can send our matrix to any state without regard for THC legality. One of our recent products in an immunity tincture which contains CBDA and CBGA, which have been shown in vitro to help reduce incidence of infection from SARS-CoV-2. I may not have all the answers, but ask me anything!

By the way, proof it’s me!

Sorry for the delay, everyone, had a bit of a technical hiccup. We're on as of 1:23 PM Eastern.

Before its founding in 2015, Embark founders (and brothers) Adam and Ryan Boyko traveled around the world collecting DNA samples from village dogs to learn the history of dog domestication. Adam's lab at Cornell University also uncovered the genetic basis for many dog diseases and traits. They founded Embark to bring those insights to pet owners and to put their discovery work in overdrive. Embark has since become the most scientifically advanced and highest-rated dog DNA test on the market.

He is currently a research scientist at the Moore Institute for Plastic Pollution Research. - Emin Israfil - is the lead developer at Rubbish, and a fellow trash and data enthusiast. He will be tech support for the journey to make sure all the litter data gets captured along the way.

  • Danielle Deltorchio - is the co-founder of Brewtrails (@Brewtrails), a Santa Cruz/Bay Area-based hiking meetup where hikers of all experience levels can come together to explore the outdoors and enjoy craft beer from local breweries.

It's 9:20pm CET: Wow, thank you all for your questions and for joining the AMA today. It was more than I expected and I tried to answer as much as possible and now my brain is pudding. Signing off for today. If you want to ask more stuff, maybe ask others from the team, head over to r/kurzgesagt or checkout our (independent) discord community.

Again, thank you for your watching our videos. Doing Kurzgesagt is truly a privilege and a dream job. You are making this possible. The entire team and I appreciate it more than you can imagine.

I was really bad at school and I dropped out of high school at age fifteen and generally was a pretty stupid and not interested in learning anything. While pursuing my secondary school diploma I met a remarkable teacher (thanks Frau Reddanz!) who inspired a passion for learning and understanding the world in me. (Mostly by screaming at me passionately). This changed how I looked at anything education related - school really made stuff horribly boring but with passion and a different teaching approach everything actually became super interesting.

So I went on to study history but that was boring too ( university, not the subject) and finally I switched to communication design with a focus on infographics, wanting to make difficult ideas engaging and accessible. During that time Edu Youtube became big and I ended up doing a video as bachelors thesis.

This project became one of the largest sciency channels on YouTube over the course of the following eight years. (It is still pretty funny to me as I'm the most unlikely person too that should explain people anything about anything) Today we have more than 16 million subscribers and 1.5 billion views on our main channel on YouTube and a team of 45 individuals working full time behind the scenes of the channel. We are known for the insane amount of hours we put into every video, which currently is north of 1200+ hours per video. Also we only published 150 videos in 8 years.

For the last decade, I've been working on and off on a book about the immune system, and decided to finish it during the pandemic, as it (obviously) felt like the right time. In the book, I take you on a journey through the fortress of the human body and its defenses and discuss a few diseases and how amazing your defenses are. The book happens to be released today if you want to check it out!

After 20+ years of research and genotyping more than 3 million dogs and cats, we’ve developed DNA tests that give pet parents the knowledge to make smarter choices at every stage of life for their pet.

We’ve dedicated years to building the world’s largest reference database for both dogs and cats, supporting detection of 350+ and 70+ breeds, respectively. Last year, we released a new dog breed detection system, and based on rigorous and controlled tests using thousands of purebred samples, it's over 98% accurate—the most accurate available on the market.

Our dog DNA tests screen for genetic conditions with up to 210 heath tests and reveal the “why” behind your dog’s physical features with over 35 trait tests. Our newest product, Complete for Cats, screens for genetic risks in cats with over 45 health tests, identifies feline blood type and has over 25 trait tests.

We’ve recently launched Relatives, our newest feature for dogs, supported by the largest pet genetic network ever to be assembled. Find your dog’s family—Relatives reveals genetic relationships for more than 99.9% of pet parents’dogs.

We're excited to share the science behind our tests and answer any questions that you may have about them and what they mean for modern pet care. So, ask away!

Science I’m Aled Roberts, a scientist at the University of Manchester, and I developed a way to potentially make ‘concrete’ on Mars using astronaut blood and urine. AMA!


Hi everyone, Aled Roberts here. I’m here to answer any of your questions about this project.


Sending materials to Mars is really expensive, so future human colonists on the Red Planet will need to make use of any resources they can obtain on the planet itself. This concept is known as in situ resource utilization (ISRU) and typically focusses on using Martian dust and rock (also known as regolith), water deposits and atmospheric gasses. Of course, humans will also be present on any crewed mission to Mars, so it makes sense (in my mind) to consider them as a potential source of natural resources too.

In this study, we found that a common protein from human blood plasma (called human serum albumin, or HSA) could act as a surprisingly strong binder (or glue) for Lunar and Martian regolith, forming a strong concrete-like material – which we’ve termed AstroCrete (astronaut-concrete).

Furthermore, we found that a common chemical obtainable from urine (urea) could increase the strength of the materials by up to 300% in some instances.

Project background:

We were trying to develop a bio-based adhesive made from synthetic spider silk, when we accidentally found that a protein from cow blood (called Bovine Serum Albumin) stuck glass together really well. Since it could stick glass, we figured it would also stick sand together – since glass and sand are made out of the same stuff (silicon dioxide). A quick test confirmed this. We then figured it should also be able to stick moon and Mars dust together too – since these are also mainly silicon dioxide.

But then we thought, we can’t realistically take cows to the moon/Mars – but HUMANS will be there on any crewed mission anyway – so could we use the equivalent human blood protein instead?

What we did it:

The process is quite simple. Essentially you can buy the protein from a supplier, dissolve it in water (optionally adding urea, also obtained from a supplier) then infuse it with simulated moon/Mars dust (again obtained from a supplier) in a disposable syringe – then heat it to 65 Celsius overnight. By the morning, the materials are dry and hard.

Next steps:

I have a few mad ideas that I’d like to explore next, including:

· Materials made from human skin. Seriously, humans shed a lot of skin, and on a trip to Mars this will accumulate in the air filtration systems. I’d like to see if anything useful could be done with it.

· A material I call “Sement”. I won’t elaborate.

· Using plant-based proteins instead of human-derived proteins. Not as exciting, but more realistic.

Some other FAQs:

· You can take the protein from blood plasma and put the blood cells back in the body, so it’s less strenuous than giving blood

· Humans are constantly producing and breaking down this protein, and generate it at a rate of about 12 – 15 g per day

· The WHO says healthy adults can give two 1.2 litre donations of plasma per week, the concentration of the protein in blood plasma is about 40 – 45 g per litre

· Urea is a colorless, odorless and harmless substance. Humans produce about 30 g of urea per day in their pee, it's also present in sweat and tears

· The astronauts will need to eat and drink more to make up for the lost calories and protein, but we don't see this as a huge issue since food will probably be produced in surplus anyway (redundancy in case of a disaster such as crop failure)

· Plants could largely fix the lost elements (H, C, N, O etc.) into food for the astronauts, from resources available on Mars (water, CO2, N2 etc.)

· The extracted protein could be stored and have other applications, such as in healthcare (for example, restoration of blood volume or as a surgical adhesive) or as an emergency food

Edit: Forgot the proof, here it is

Edit 2: Sorry for leaving people hanging for a while, I didn't realize how to close the post down properly (I did it as a comment rather than editing the main post)

Closing edit:

Thanks for the questions everyone, I had some really engaging discussions but my brain is now fried so I’m going to sign off for the evening. I hope to pop back later to answer a few more though. Hope you found this interesting and hopefully I’ll be back in the future to answer questions about my next mad ideas.

A convoluted offshoot of this technology has been my start-up, DeakinBio, which uses plant-based proteins and other Earth-based substances to make inorganic-biopolymer hybrid materials (or bio-hybrids). I'm trying to make relatively green alternatives to cement and ceramic materials, with a particular focus on making materials from captured carbon (in the form of carbonate minerals).

If you’d like a sample of AstroCrete (or any other material I've developed with my start-up) I’m selling a limited batch of 20 (of each) through my shop. All proceeds go towards further research and development.

I'm currently self-funded (and working from my basement, mad-scientist style) so any support would be greatly appreciated.

Thanks again,

Science I am John Horgan, a science writer obsessed with quantum mechanics, the mind-body problem and the mystery of who we are. AMA.


Both as a science writer and a human being, I’m obsessed with the mystery at the heart of things, the mind-body problem. In a narrow, technical sense, the mind-problem asks how brains make minds, but it really poses a deeper question: What are we? Are we matter? Genes and neurons? Computer programs? Souls? All my books, from The End of Science to Pay Attention, grapple with the mind-body problem. Since the beginning of the pandemic, I’ve been studying quantum mechanics, which is related to the mind-body problem. I've written a bunch of columns for Scientific American on quantum mechanics over the last 16 months, and I'm writing a book about it now. I'd love to talk to Redditers about the mind-body problem, quantum mechanics and related topics. I’d also be happy to talk about why I’m an optimist, at least on good days.

Science I am Will Marshall, CEO of Planet, and I’m here to talk to you about going to space to build a data company using the world’s largest fleet of Earth observation satellites. Ask Me Anything!


Hi Reddit, I’m Will, a former NASA scientist with a PhD in quantum physics from Oxford and currently the Co-Founder and CEO of Planet (see video below). Planet operates 200 satellites that collect images of the entire Earth’s landmass every day (for the first time in history!) -- to help us take care of our planet.

I believe we are entering a space renaissance that will change how we see and measure our environment and understand our planet. Planet’s data is being used today in various ways that show just the tip of the iceberg (pun intended) for what will be possible tomorrow.

In short, I am excited to talk about building little spaceships to help us to take care of our favourite spaceship, the Earth :) As a space geek, I love the space community, and am looking forward to discussing everything from physics and satellites to ecosystems to aliens:)
