Meat from predators is very gamey - and an obligate carnivore like a cat would be the worst.

This is a bigger problem the higher up the foodchain you go, so giving your cat Bluefin is worse (not to mention much more expensive) than the common stuff (albacore or light tuna) that comes in a can. And of course it's even worse for humans, for the same reason - and we live longer so the heavy metals have more time to accumulate.

I think this is it exactly, and in fact I found a Science Daily article that explains the cleverness of it (your assumption about the time scale is correct, and they have a clever arrangement of diodes that let you kind of "pump" the charge out). They specifically mention not violating the 2nd Law too :)

It's definitely not extracting energy from the vacuum. It's converting latent heat energy into electrical energy due to clever engineering and the quirky properties of graphene.

Sadly it's not extracting energy from the quantum flux :) But happily, it is extracting energy from the heat of the world -- of which there is plenty (enough for us to treat it as unlimited).

It's more like a generator that uses ambient heat as the "battery". With previous systems you could only extract useful work from heat if you had a heat gradient (e.g. one area that's hotter than another). With this invention the innovation is that graphene's unique combination of thinness and conductivity basically let you convert the brownian "heat" of the substance itself (not the environment) into electricity.

Don't go boating in a storm, folks.

As an anecdote, I work at a midsized software company as a product manager. I have an international team of about 20 that I manage from home (full-time remote). Overall there is some loss of speed and agility versus having a full-time in-office staff. I'm not a fan of trying to quantify productivity per se, but for things like estimations and deviations there's no question that in my environment at least, things move a little slower and take a little longer. Now personally, the fact that we can hire engineers anywhere across the globe (including in LCOL areas), don't have to pay rent and related fees, and that some of the best engineers specifically want full-time remote more than outweighs the reduced agility (putting aside all of the other potential QOL benefits) -- and if needed, some of the savings from reduced rent and salaries could be used to expand the team anyway. Thankfully my management team agrees and has continued to pursue a remote/hybrid environment. But for those places that value speed and agility most it could be a bit of a problem.

Yeah, a better title would have been "new observations show gravity anomaly indicating that current dark matter theories are incomplete", but you get fewer clicks with something like that, right?

I just watched that video somewhat recently and couldn't understand that quote. There are a number of MOND models that literally don't involve dark matter at all -- no new particles added, no unexplained masses needed. So in that case, wouldn't "how we combine them" just be "set dark matter to 0 and use this different set of equations to solve for gravity in certain circumstances"?

I worked in a field that managed a lot of technology in retail stores. The big ones know everything about you, it's just astonishing. At the time (around 15 years ago) there was very little oversight, but also most CIOs were inept and couldn't really make the data sing and dance. Today that is very much no longer true, and it's almost too easy to build a comprehensive profile of an "anonymous" guest and then attach it to their personally identifiable information, all without their consent or knowledge.
