This particular use of CRISPR-Cas9 should be pretty low risk. Tumors are often surrounded by lymphocytes, cells which ordinarily have the power to kill cancer cells -- but many cancers give off signals that cause the lymphocytes to ignore tumors cells and let them grow. It's like the mafia buying off the local cops. Modifying tumor-reactive lymphocytes ex vivo might wake them up and help them do their job and go after the tumor again. In a patient with terminal cancer, this treatment should be pretty low risk and could give him a bit longer to live.

Submission + - The Paradoxes That Threaten To Tear Modern Cosmology Apart

KentuckyFC writes: Revolutions in science often come from the study of seemingly unresolvable paradoxes. So an interesting exercise is to list the paradoxes associated with current ideas in science. One cosmologist has done just that by exploring the paradoxes associated with well-established ideas and observations about the structure and origin of the universe. Perhaps the most dramatic of these paradoxes comes from the idea that the universe must be expanding. What’s curious about this expansion is that space, and the vacuum associated with it, must somehow be created in this process. And yet nobody knows how this can occur. What’s more, there is an energy associated with any given volume of the universe. If that volume increases, the inescapable conclusion is that the energy must increase as well. So much for conservation of energy. And even the amount of energy associated with the vacuum is a puzzle with different calculations contradicting each other by 120 orders of magnitude. Clearly, anybody who can resolve these problems has a bright future in science but may also end up tearing modern cosmology apart.

That's not the way do to it. The camera should be recording for the whole shift, but if the officer doesn't unholster a weapon, that day's footage gets erased at the end of the shift. If a weapon is drawn, footage around that event would be saved. Less privacy worries for the officers, and more incentive for them to resolve situations without firing.

I feel your pain. I wear progressives, and for my first pair, the optimal focal area was ridiculously small just as you describe. A couple of years ago I went to a new optometrist and explained that I wanted glasses that had a more natural feel for close viewing. That 'spot' effect isn't there, and I love them.
