The New York TimesVerified account @nytimes May 2, 2020

New data from space is providing the most precise picture yet of Antarctica’s ice, where it is accumulating most quickly and disappearing at the fastest rate, and how the changes could contribute to rising sea levels.

A satellite lets scientists see Antarctica’s melting like never before

excerpt:
ICESat-2, he said, “reveals the process of change, and without understanding those processes you have no ability to make predictions.”

“It really just gives us this incredibly crisp, unified picture.”

An excellent overview by Dr Anthony Fauci on the how scientists establish the origin of the COVID 19 virus.
Also offers sound advice on deciding what sources should be trusted in this contested discussion

Fauci: No scientific evidence the coronavirus was made in a Chinese lab
In an exclusive interview, the face of America’s COVID-19 response cautions against the rush for states to reopen, and offers his tips for handling the pandemic's information deluge.

I thought was a really cool video on how Japanese honey bees combat giant killer hornets.

My mate works for AARnet, and was involved in the SKA. It was always about bandwidth. (Best job he'd been involved with, he said)

I've always viewed concerns over 5G as a storm in a teapot and perhaps tin foil hat material.

But then I spot this.... Hmmmm

 

[basilio]

Debunking 5G .

 

[wayneL]

I don't think Werner's cites are CV related bas (and I'm certainly not on board with that). Haven't deep dived into it yet, but an interesting rabbit hole to go down some time.

You wouldn't put your head in a microwave or read a book in front of a radar so caution is required, the shorter the wave, the more potent it becomes.
Am i afraid of 5g, not really, will it cause cancers.. aka mutations..most probably but as 0er mobile phone etc, always remember that the energy/ exposure decreases by the cube of the distance
So a phone near your male parts or by your ear is quite different from one on the table 1m away.
Moderation...
Not having an antenna on your bedroom window etc
We get hit by cosmic solar waves, background radiation,EM fields etc
In my view, quite harmless but not fully harmess

I didn't think modern cell phones emit 'ionising' radiation

And, though it doesn't mean anything (coincidence, correlation, causation), as emerged in popular culture, “Every day, it has been estimated, between one and five of your cells turns cancerous and your immune system captures and kills them" =- Bill Bryson; The Body - a Guide for Occupants. With some 37 trillion cells in the body, there's a lot going on.

Old TV sets were essentially Cathode Ray Oscilloscopes. When I did my NSW Radiation Operators Certificate in 1980, the notes mentioned the Act had been changed in the sixties to specifically exclude TV's from being radiation devices. The old saw about sitting too close and damaging your eyes was nonsense, but useful; a bit further away diminishes exposure to radiation by the cubic power law.

Any building built of granite emits radon gas in measurable amounts; in Aberdeen, Scotland, its quite high. Exposure to 100 mSv a year is the lowest level at which any increase in cancer risk is clearly evident.

Where did i mention 'ionising'?
4g but all others 3g 2g etc as well are emitting energy which is absorbed by the walls the cells inc your body.
We are cooking ourselves and some of this energy will statistically alter some molecules.
Stats will say that yes some people will have cancer due to 4g but true, most not, or not because of 4g.
On the other hand, 4g will save lives
A balance
4g has shorter wave lengths more energy, and least range as more easily absorbed instead of rebounding.
Just basic physics so yes it is more dangerous than previous bands
No hystery but also no denial
