There are many different causes of the scarring. Viruses are common. Hepatitis B, hepatitis C, what we call autoimmune diseases where the body attacks the liver itself such as primary biliary cirrhosis is an autoimmune disease; sclerosing cholangitis is an autoimmune disease; and so those diseases where the liver is being destroyed by either the virus or an autoimmune disease, it can only scar, and why it doesn't regenerate has to do with the fact that there is this ongoing scar tissue that blocks that regeneration.

We cannot deny that our decision today will have an impact on the ability of law enforcement to combat crime. Cell phones have become important tools in facilitating coordination and communication among members of criminal enterprises, and can provide valuable incriminating information about dangerous criminals. Privacy comes at a cost.

Trivial facts are often the best hints to what is going on.

If it's a situation in which the public is being given access, you can't discriminate against the media and say, as a general matter, that the media don't have access, because their access rights, of course, correspond with those of the public.

By ensuring that no one in government has too much power, the Constitution helps protect ordinary Americans every day against abuse of power by those in authority.

I think judicial temperament is a willingness to step back from your own committed views of the correct jurisprudential approach and evaluate those views in terms of your role as a judge. It's the difference between being a judge and being a law professor.

When we think about living donor transplant, what we're banking on is the ability of the liver to regenerate itself. Now, it's not the same sort of regeneration we think about with the starfish where we cut off the arm and it grows a new arm. With the liver, what happens is the remaining liver gets bigger, and your body knows the size of the liver that it needs, and when it recognizes that there is not enough liver, it sends nutrients and signals to the liver and says "get bigger."
