The lasers are very specific, and tissue dispersion is fairly limited. We get about 5 mW at the point of exposure, and that produces a cone maybe 2mm deep and 1.5 mm in diameter. Some researchers use micro-LED arrays that allow them to get very specific spatial discrimination, but our lab doesn’t really need that kind…

We use adeno-associated virus to transfect them, so expression is relatively local to the injection site. For me that’s the hippocampus. Using certain promotors, we also tailor the channels so that they’re only expressed in specific neuron populations.

Wouldn’t you like to know.

We transfect them with a few different photoreceptive channels (opsins). Calcium channels for inhibition and nonspecific cation channels for excitation. We also implant wires as a means to measure activity.

Medical research on the prison population is a huge ethical violation. They’re too vulnerable to manipulation to genuinely consent to anything.

I’m a research scientist that works with mice. I don’t see anything objectionable here, as long as they’re following proper animal care and use guidelines.

Sharks don’t care for their young like mammals do, so there’s no need.

Think of the puppies!

I think it has to do with living relatives. Nobody is going to personally remember some foot soldier who died in the 12th century. But there are WWII veterans alive today. There are WWII and WWI wrecks that are popular diving locations, but those are usually scuttled ships that weren’t full of crew when they sank. I…

Because that’s exactly what some people are advocating.

Just air. The reactor heats the air drawn in from the intake.

What hunters are you talking to? Almost all hunters use some sort of ballistic tip bullet, which is a hollow-point bullet with a plastic tip. The plastic tip just gives the bullet better aerodynamic performance during flight. Once it hits the target, the plastic disintegrates and the bullet expands like a typical…

What stood out to me was that these only included firearm-related injuries in patients with private insurance. Most of the population with poor gun-safety skills are not privately insured. They’re undereducated/impoverished or criminals.

The Russian economy relies on foreign currency reserves. The Ruble would be worthless without those reserves, and Putin is blowing through his rainy day fund pretty damn quick.

The problem is that Putin will run out of money long before the US does. The Russian economy is a joke compared to the Soviet economy, while the US economy is stronger and less vulnerable.

Charles Whitman killed 14 people with a bolt action rifle.

While I don’t agree with your conclusion, your reasoning is spot on. Since the early 1960's, no modern military has fielded (as standard issue) a semi-auto rifle. They’ve all been select-fire, either full-auto or burst. That would make them either an assault rifle or battle rifle depending on caliber. Before that it…

“You have a tiny dick” has to be the dumbest part of the whole gun control argument, and immediately discredits the party that brings it up.

They’ve gone off the deep end by trying to become an all-encompassing, Trumpy political organization. Most “reasonable gun owners” I know are no longer members.
