Submission + - Birth of a Solar System Witnessed in Spectacular Scientific First (sciencealert.com)

alternative_right writes: Around a Sun-like star just 1,300 light-years away, a family of planets has been seen in its earliest moments of conception.

Astronomers analyzed the infrared flow of dust and detritus left over from the formation of a baby star called HOPS-315, finding tiny concentrations of hot minerals that will eventually form planetesimals – the 'seeds' around which new planets will grow.

Good point. An army that sees all others as subhuman and sees only the next death is one that has to keep fighting. It has no choice. It's the only thing it knows. It can keep conquering more territory outwards, or it can slaughter its own government inwards. History shows those are your two options.

Whether or not Russia conquers Ukraine, it will attack other countries - vast numbers of bored, underpaid soldiers would seek entertainment elsewhere if they didn't.

This is what I'm going by:

The report said that in December 2018, the US Federal Aviation Administration issued a special airworthiness information bulletin based on reports from operators of model 737 planes that the fuel control switches were installed with the locking feature disengaged.

The airworthiness concern was not considered an unsafe condition that would warrant an airworthiness directive – a legally enforceable regulation to correct unsafe conditions.

The same switch design is used in Boeing 787-8 aircraft, including Air India’s VT-ANB, which crashed. The report added: “As per the information from Air India, the suggested inspections were not carried out as the SAIB was advisory and not mandatory.”

1. Were the safety guards, which were optional, installed?

2. We know investigators are looking into the computer system, does this mean the computer can also set the switch settings?

If the answers are "no" and "no" respectively, it was likely an accidental bump.

If the answers are "yes" and "no", then one of the pilots lied.

If the answer to the second one is yes, then regardless of the answer to the first, I'd hope the investigation thoroughly checks whether the software can be triggered into doing so through faulty data or the existence of software defects.

Agree with all your points.

It's possible I might have missed these, but they're also major considerations with COVID:

1. It causes scarring of tissue, especially heart tissue. That's why COVID sufferers often had severe blood clots in their bloodstream. Scarring of the heart increases risk of heart attacks, but there's obviously not much data on by how much, from COVID. Yet.

2. It causes brain damage in all who have been infected. Again, we have very little idea of how much, but from what I've read, there may be an increased risk of strokes in later life.

3. Viral load is known to cause fossil viruses in DNA to reactivate silenced portions. This can lead to cancer. Viral load has also been linked to multiple sclerosis and chronic fatigue, but it's possible COVID was the wrong sort of virus. These things can take decades to develop.

I would expect a drop in life expectancy, sometimes in the 2040-2050 timeframe, from life-shortening damage from COVID, but the probability depends on how much damage even mild sufferers sustained and what medicine can do to mitigate it by then. The first, as far as I know, has not been looked at nearly as much as long COVID has - which is fair. The second is obviously unknowable.

I'm hoping I'm being overly anxious, my worry is that I might not be anxious enough.

My latest vaccine shots had the 6G upgrade, to take advantage of the higher-speed web access when the networks upgrade, but if they're selling those frequencies to high-power carriers, then I won't be able to walk into any area that handles AT&T or Verizon. :P

Seriously, this will totally wreck the 6G/WiFi6 specification, utterly ruin the planned 7G/WiFi7 update, and cause no end of problems to those already using WiFi6 equipment - basically, people with working gear may well find their hardware simply no longer operates, which is really NOT what no vendor or customer wants to hear. Vendors with existing gear will need to do a recall, which won't be popular, and the replacement products simply aren't going to do even a fraction as well as the customers were promised - which, again, won't go down well. And it won't be the politicians who get the blame, despite it being the politicians who are at fault.

Submission + - MIT chemical engineers develop new way to separate crude oil (thecooldown.com)

fahrbot-bot writes: The Cool Down is reporting that a team of chemical engineers at the Massachusetts Institute of Technology has invented a new process to separate crude oil components, potentially bringing forward a replacement that can cut its harmful carbon pollution by 90%.

The original technique, which uses heat to separate crude oil into gasoline, diesel, and heating oil, accounts for roughly 1% of all global energy consumption and 6% of dirty energy pollution from the carbon dioxide it releases.

"Instead of boiling mixtures to purify them, why not separate components based on shape and size?" said Zachary P. Smith, associate professor of chemical engineering at MIT and senior author of the study, as previously reported in Interesting Engineering.

The team invented a polymer membrane that divides crude oil into its various uses like a sieve. The new process follows a similar strategy used by the water industry for desalination, which uses reverse osmosis membranes and has been around since the 1970s.

The membrane excelled in lab tests. It increased the toluene concentration by 20 times in a mixture with triisopropylbenzene. It also effectively separated real industrial oil samples containing naphtha, kerosene, and diesel.

On exactly what the detector is capable of detecting. If they're looking, at any point, for radio waves, then I'd start there. Do the radio waves correspond to the absorption (and therefore emission) band for any molecule or chemical bond that is likely to arise in the ice?

This is so basic that I'm thinking that if this was remotely plausible, they'd have already thought of it. This is too junior to miss. Ergo, the detector isn't looking for radio waves (which seems the most likely, given it's a particle detector, not a radio telescope), or nothing obvious exists at that frequency (which is only a meaningful answer if, indeed, it is a radio telescope).

So, the question is, what precisely does the detector actually detect?

Back in the days of the Rainbow series, the Orange Book required that data that was marked as secure could not be transferred to any location or user who was (a) not authorised to access it or (b) did not have the security permissions regardless of any other authorisation. There was an additional protocol, though, listed in those manuals - I don't know if it was ever applied though - which stated that data could not be transferred to any device or any network that did not enforce the same security rules or was not authorised to access that data.

Regardless, in more modern times, these protocols were all abolished.

Had they not been, and had all protocols been put in place and enforced, then you could install all the unsecured connections and unsecured servers you liked, without limit. It wouldn't have made the slightest difference to actual security, because the full set of protocols would have required the system as a whole to not place sensitive data on such systems.

After the Clinton email server scandal, the Manning leaks, and the Snowden leaks, I'm astonished this wasn't done. I am dubious the Clinton scandal was actually anything like as bad as the claimants said, but it doesn't really matter. If these protocols were all in place, then it would be absolutely impossible for secure data to be transferred to unsecured devices, and absolutely impossible for secure data to be copied to machines that had no "need to know", regardless of any passwords obtained and any clearance obtained.

If people are using unsecured phones, unsecured protocols, unsecured satellite links, etc, it is not because we don't know how to enforce good policy, the documents on how to do this are old and could do with being updated but do in fact exist, as does the software that is capable of enforcing those rules. It is because a choice has been made, by some idiot or other, to consider the risks and consequences perfectly reasonable costs of doing business with companies like Microsoft, because companies like Microsoft simply aren't capable of producing systems that can achieve that kind of level of security and everyone knows it.
