I’m Francis Collins, Director of the National Institutes of Health. As we celebrate the 15th anniversary of the completion of the Human Genome Project, I’m here to talk about its history and the critical role it has played in precision medicine. Ask me anything!

Sometimes called “wear and tear” arthritis, osteoarthritis in people who are obese was long assumed to simply be a consequence of undue stress on joints. But researchers provide the first evidence that bacteria in the gut – governed by diet – could be the key driving force behind osteoarthritis.

Superionic ice has been created in the lab for the first time. The ultra-conductive version of ice, which accounts for 60% of Uranus and Neptune, was formed by compressing ice to 25,000 times the atmospheric pressure felt at sea level. The resulting ice was sixty times denser than regular water.

8 sciencegeek111 Are the flaws in this science only applicable to bullet forensics or are there errors in things like fingerprint analysis too?
6 nate Based on your evaluation of the methods and evidence, do you believe that there was a second shooter on the grassy knoll?
5 scienceaccount103040 I don't know much about the JFK case. Could you explain, in laymen's terms and in enough words, why the combative bullet lead analysis was flawed? And what came of the flaw?
3 earlysong Hi Dr. Spiegelman, As science grows more complicated, it becomes more and more difficult to explain it adequately to the average person (ie, the jury). Do you think this has any effect on the outcome of cases; for example, do you think juries are simply "led" by lawyers without properly understanding the scientific evidence? Are there any other "popular" forensic tests that are likely on their way out as we raise our scientific standards? Thank you for your time today.
3 adenovato Do you see machine learning becoming a more significant part of forensic science moving forward? Will we trust an expert AI to make appropriate analyses over people? Or is that a step too far for the court system in our lifetime?
4 scienceaccount103040 What can we do? Anything? What should the government do?
4 a_casual_sniff What was the most memorable case you worked on with the Innocence Project? thanks
3 Cliff_Spiegelman Alright, it’s time for me to sign off. Thanks for all the great questions, it’s a been a pleasure!
3 adenovato How dire is the situation as it pertains to bad forensic science and the criminal justice system? From fingerprints to bite analysis to hair analysis and beyond... where is your level of concern?
3 Cliff_Spiegelman I am here to answer any questions
3 amurrca1776 Hello Dr. Spiegelman, I expect a lot of people will be asking about JFK, so I'll leave those questions to them. Rather, I'm more curious about your appointment as Official Statistician of the Texas Holocaust and Genocide Commission. What is this role and how does your background in forensic science factor into the duties and responsibilities associated with it?
3 sciencereader3455 Which state innocence project is the most effective?
3 earlysong How difficult is it to "throw out" something like bullet lead analysis from scientific practice as a whole? How do legal teams find out that a certain test should no longer be used?
3 gingerrabbit19 Dr. Spiegelman, Can you tell me a little about how you got started on this? How does a statistician get involved in forensic bullet analysis? Thank you for your time!
3 shana93 Hi, Dr. Spiegelman! What would you say is the most interesting project you're working on right now? Thank you for your time this morning.

2 adenovato What sort of hurdles do you experience in your role at the Texas Holocaust and Genocide Commission?
1 a_casual_sniff Do you know of scientific and statistical methods that have the most promise for being used effectively and reliably in the modern courtroom? DNA evidence appears to be the most reliable now, but I am wondering what you think about other methods such as microbiome signatures or mass spectrometry. Thank you for your time!
