Reply to comment by perkeleaf in Canadian universities have been conducting joint research with Chinese military scientists for years by No-Drawing-6975
Relying on the honor system for almost all universities to turn down money in aid of democracy is pretty rich.

Reply to Canadian universities have been conducting joint research with Chinese military scientists for years by No-Drawing-6975
"Margaret McCuaig-Johnston, former executive vice-president of NSERC and now senior fellow at the Institute for Science, Society and Policy at the University of Ottawa, noted that the new security guidelines only cover federal grants and not individual academic research with China’s military. China offers a lot of money to Canadian researchers and universities to work with them, she said.
“The People’s Liberation Army is not our friend and we should not be partnering with them,” she said. “Any collaboration with the National University of Defence Technology is clearly going to a military purpose and Canadian researchers should be using their own personal ethical lens to decide not to move forward with that research.”
...
Dennis Molinaro, a national-security analyst and professor at Ontario Tech University, said “there is a lot of passing the buck” taking place on the subject of university research with China.
The universities say they need clarity from government on risks posed by their joint research. But CSIS, for instance, which gathers intelligence on foreign threats, is prevented from sharing specific details with Canadians – even with law enforcement unless it’s specifically for prosecution and regarding a criminal offence.
“Each are relying on the other to do the right thing, meaning the university wants to know what specific threat exists so it doesn’t curb academic freedom, and the intelligence sector wants the university to act on the basis of, in essence, ethics, that partnering with this kind of institution in the PRC is unethical,” Mr. Molinaro said.
He said the federal and provincial governments need clearer guidelines for academic partnerships and legislative reform to the CSIS Act that enables the spy service to talk more openly about threats that exist."

Reply to comment by marcthe12 in UK says Russia set to give Iran military tech that will destabilize Middle East by nahalkishon
Makes sense as Iran is apparently stocking up on enriched uranium (some ~60%).
Hopefully, this doesn't spiral into WW3.

To substantially reduce cable taper--if we reach a point where mass produced graphene powder (but not solid graphene structures) is economical--an extremely strong material like carbon fiber or UHMW might be impregnated with graphene powder for enhanced strength (and other attributes such as creep resistance). Another means to keep cable taper reasonable may be to attach hydrogen balloons (perhaps with a helium liner) along the sides of the cable (that are capable, via telescoping arms perhaps, to fully or partially detach to permit vehicle travel).
The cable length might also be supported in space by nuclear or electric spacecraft pulling on it (being fueled or electrified via elevator cable) to further reduce taper and/or permit more/heavier traffic.

Brannigans Laws:
- No killbot shall exceed 9 kills during fully autonomous operation.
- No killbot shall be permitted to hit the reset button on another killbot.
- No killbot shall operate in a fully autonomous state unless remote operation is interrupted by the enemy.

Reply to At CBD:THC ratios most common in medicinal and recreational cannabis products, no evidence found that adding CBD protects against the impairment or subjective effects of THC/cannabis - a randomised double-blind trial with 46 people. by drdrugsandbrains
While not particularly relevant to the aim of this study, CBD is often dosed in the hundreds of mg (with doses around 1g/day being evaluated for schizophrenia).

Here's a review of the paper: https://earthenvironmentcommunity.nature.com/posts/developing-electrokinetic-mining-technology-for-recovering-rare-earth-elements-from-weathering-crusts
1 year old paper in (in situ) electrokinetic mining: https://www.science.org/doi/10.1126/sciadv.abf9971
TLDR: dissolve rocks with chemicals and move ions (potentially selectively) with electricity.

Reply to comment by ZoneEnder666 in If the inner core is the hottest part of the Earth, hotter than the liquid outer core, then why is it a solid? by Paradigm7657
At a hypothetical exact center of the Earth (assuming, for argument's sake, equal distribution of elements/density in the Earth), a particle of matter would be pulled equally in all directions--balancing out; nevertheless, there is a column of matter on all sides of said particle pushing down on it.
From what I gather, it's believed that there is significant but not extremely substantial heat generated from ongoing rasioactive decay. (It's thought that billion uranium deposits may have naturally undergone criticality/self-susutaining fission.)
The state of matter is a function of both temperature and pressure. Propane at modest pressure can be stored as a liquid that turns into a gas at atmospheric pressure during use. Water in a pressure cooker (about 2x atmospheric pressure) has a boiling point of around 120 degrees C; conversely, food cooked on a tall mountain may take much longer due to a less massive column of air pressing upon the water (which lowers its boiling point).

Reply to Canada restricting foreign state-owned firms from critical mineral industry by NineteenSixtySix
China will likely respond to this and similar developments in other countries by investing more heavily in Africa and Western governments should consider facilitating or even subsidizing further operations there.

If cost of power (is fuel vs grid electricity) is the main factor, then aerodynamics are more important on a gas/diesel vehicle--especially at highway speeds where power consumption shifts towards air resistance induced by higher speeds vs the greater weight of EVs. If range is the major consideration, then electric.
Presumably, as EVs typically have a "skateboard" design with a layer of batteries near the base, it would be easier to design the front of a BEV for greater aerodynamics.

It appears playing both sides is often a good tactic middleish powers with enough bad behaviour that they'll get limited Western support.
