The actual Science article says: "Earth’s ozone layer blocks the Sun’s shortest wave UV radiation, called UV-C.", which is correct. UV-C is the band with the shortest wavelength within the ultraviolet band. X-rays and gamma rays are not within the ultraviolet band.

It isn't, but in Japan as in many other cultures the woman is considered to have joined her husband's family and her showing respect for his family is more important than him showing respect for her family.

This seems like a very odd way for a pilot to commit suicide. On take-off its hard to say what will happen to the plane. It would be a surer bet if he waited until the plane was at altitude and then made it dive..

These ovens are apparently complex and hi-tech. They reportedly operate like pressure cookers, can be monitored wirelessly, and can be programmed for particular dishes. https://www.stripes.com/branch...

Really? I have had no problem running Zoom for years on Ubuntu.

Not necessarily. Since most of the injuries are apparently due to burns it is not unreasonable to think that a large percentage of those taken to hospital will not survive even in a very good hospital. I don't think it need be taken as about the quality of Indian hospitals.

That's a likely cause of failure of both engines, but there are also reports that the landing gear was still down and the flaps in take-off position, which would have accelerated its descent.

No, we know it did not happen that way, Nothing abnormal happened on the runway. The plane took off but stalled and therefore descended past the runway into an area full of buildings, where it crashed and caught fire.

Exactly. People seem to have forgotten about the Xanadu project.

How about a situation in which the police are monitoring an informant or undercover police officer who is with the criminals. They're waiting for something to happen before they enter to make arrests or search, or they're ready to go in and protect their CI or undercover officer if things go wrong. What if one officer wants to tell another that he thinks that the bad guys suspect the informant and they should prepare to move in? He may not name the CI, but if the criminals hear this, bad things will happen. Similarly, how about a hostage situation where a sniper needs to communicate that something has changed and he no longer has a shot? Situations like these call for immediate communication.

There have been criminal investigators in China for over 1,000 years. Each "county" (hsien) was governed by a magistrate, who was charged, among other things, with investigating crimes. He had staff to assist him, including officers who functioned as police officers and a local physician who served as medical examiner.

How do they communicate it? Some of these things need to be communicated rapidly - they can't rely on face-to-face communication.

A possible solution is for the encrypted signals to be automatically stored by a third party, a kind of escrow service. The public would automatically gain access to the stored material after a certain amount of time. The police would be able to flag certain communications as requiring longer term secrecy (say those containing the identities of confidential informants). Those desiring access to communications flagged as not to be released could appeal to something like a Freedom of Information panel, which would decide whether secrecy should be maintained.

Some information should not be made public, e.g. the identity of confidential informants, the existence of (legal) wiretaps, details of ongoing operations. The bill acknowledges this. How is this information going to be kept secret while most information is not? Are police to have to remember to press the "scramble" button when they want to say something secret? Are they going to have to use their phones for secrets and their official radios for public information? I'm all for careful oversight of the police, but it is far from obvious how this is to be implemented.

It sure is good to read some good news for once! And from Texas! Who expected that?
