    It's one of the aspects of the oft-complained about "lack of critical thinking". Which goes with "journalists" being ... well, as my now-deceased friend and a part-time lecturer in Journalism after running news rooms for 30-plus years would say, "staff writers". Journalists do take the time to check the sources, read the surrounding documents, and think carefully about their articles. Someone who has to turn out something to garner 3000-ad clicks or there is no food on the table tonight ... a writer yes, but not a journalist.

    Having said that, I've just been doing the diagrams to go with another submission, because I do have the (enforced) leisure time to do this sort of work.

    In the case of uncertainty, go to the original paper. That is why they are published, reviewed before publication, consulted between authors and colleagues (often also competitors in the field with the original authors). All things that don't happen in the journalism industry.

    I mean, if you think it sounds like religion, then I'd say "If I wanted to know what a Roman-era Jew said, I'd look for documents written in the Roman era by people with at least some possibility of actually having been within a few generations of being witnesses." I wouldn't waste my time with something translated through several languages from the speaker's original, a millennium and a half later.

    Of course, if I felt the need to actually research that stuff, I'd learn a lot more of the relevant languages than I have already. But I'm working on languages in 3 different groups at the moment, and I think that's far more important.

    Yes, I find paywalls around academic publishing to be damned annoying. I spend almost £200/year for access to a chunk of "the literature", and for the rest, there's Sci-Hub

    He-3 (proton+proton+neutron) is the lowest stable nucleus of Helium. I don't have a figure off-hand for the half-life of the di-proton (proton+proton) with respect to decaying to a deuteron (proton+neutron) plus electron plus neutrino, but it's probably not as long as the half life of the hydrogen atom compared to the hydrogen ion, in the plasma conditions we're talking about. Probably not by many orders of magnitude - weak force interactions tend to be a lot quicker than electromagnetic ones.

    To quote the abstract, not the press release, "During the dawn of chemistry, when the temperature of the young Universe had fallen below some 4,000 kelvin, the ions of the light elements produced in Big Bang nucleosynthesis recombined in reverse order of their ionization potential. With their higher ionization potentials, the helium ions He2+ and He+ were the first to combine with free electrons, forming the first neutral atoms; the recombination of hydrogen followed. In this metal-free and low-density environment, neutral helium atoms formed the Universeâ(TM)s first molecular bond in the helium hydride ion HeH+ through radiative association with protons." (My emphasis added)

    What self-respecting scientist could do such a thing?

    The scientists didn't. A journalist wrote the confusing phrases.

    No, scientists don't (generally) write press releases for their publications. They leave that to journalists, who might even be writing in their native tongues. Having spent an hour transliterating some French into English just after breakfast, I can understand why they leave that job to journalists.

    I have to read the headline in a special way that changes its meaning? How do I know to do that?

    Where things don't quite seem to add up, and you have reason to suspect the involvement of journalists who are journalists, not scientists. Then you have to read much more carefully. Sad, but true.

    Reading press releases or commentary instead of the actual paper is normally a waste of time and electrons if you actually want to understand the science.

    The paper in question is here, but you'll need either access to Nature to read it, or access to Sci-hub to read it.

    Yeah, I thought that at first. But the temperature range typically given for the condensation of hydrogen nuclii and electrons into monatomic hydrogen (the formation of what is now the cosmic microwave background, after around 40x stretching of space) is at several thousands of K, which would be in the orange- to green- hot temperature range. To allow something to form with an absorption band in the "far IR", you'd need to drop the temperature to somewhere below a thousand K.

    I wonder if the shifters of such boxes have considered the marketing benefits of a separate, grounded, USB board for the external sockets. Fry that and it's a 10$ fix, not a dead 250$ box - neglecting technician time.

    To be honest, I'm not sure if Lyer or Ubft even operate in my country yet. Which is probably why they're not in my phone yet. Then again, the nearest airport with more than 3 scheduled flights a day is over 3 hours travel away. And it's nearly 2 years since I last used a taxi. So, I'd hardly be propping the company up, even if they did operate in the correct countries.

    After being the first company to successfully kill someone with their self-driving car

    They might be the first company to have killed someone (not even an employee!) with a self-driving car, but they're far from the first to kill one, or even many, many employees in their day to day work.

    We do try to get the directors and owners of companies jailed for killing their employees and members of the general public, but it's an uphill battle against the "powers that be". It's one of the most important jobs of the trade union movement.

    Just jailing one director every time an employee is killed would improve the mobility in that part of business, and act as a salutary lesson to the rest. You might even let them out on parole once the investigation goes to trial. Unless the court tells them to go back inside for a decade or so.

  24. Heck, every single gun control law passed in the last 30 years has exemptions for police officers, even if the stuff isn't issued as a duty weapon/accessory.

    What?

    I may be misunderstanding this, but are you saying that Florida police have to actually buy their own guns? So, one cop in a patrol car could be carrying a 9.0678 mm bore weapon, and the cop in the passenger seat carrying an 11.43mm bore weapon, and neither able to use the other's ammunition?

    Assuming that guns are fairly expensive, I assume they're returned to the owner's next of kin after a death on duty ... and any appropriate court cases, appeals etc.

    Over here, if a piece of equipment is necessary to do a job (steel toe boots, flame-resistant coveralls, hard-hat, breathing apparatus), it's supplied by the employer, not the employee. In large part because if someone else (passer by, another worker) is injured by it, the responsibility for maintenance lays very clearly with the company director's and their maintenance procedures.
