Really cool un-intuitive science experiment. Making a vehicle propelled by the wind, go faster than the wind. And it doesn't work the way you think it does.

Really impressive! That explanation with the cylindrical earth model was awesome. Also, love the "test pushing or pulling the lever, and whichever one slows you down, do that" instruction on how to stop.

I remember arguing about that on science forums before and while they were building it and then after they tested it and showed it works. Worse than airplane on a treadmill

This seems...I dunno, useless? They only had a couple minutes up there. That's a lot of money, effort, and resources for a brief bit of zero G.
In this form yes, however this is the start of orbital air travel. They will likely leverage this tech into being able to travel across the planet in a couple of hours.
This flight should be looked at as akin to the flight at kitty hawk.

Every big journey forward needs a first step. Seems small and waste of money at first (I thought the same). But I'm sure the Wright bros got laughed at too at first. As did many other inventions throughout history that went on to become the various forms of travel we take for granted today.
A lot of it is probably a billionaire playing around with his cash to do something cool no one else gets to do. But this is a great leap forward for future air travel. Really cool to see this happen and a nice distraction from the doom 'n' gloom clouding the news these days.
I'm not really sure how it becomes the future of air travel. You need an incredibly massive launch vehicle that wouldn't work at a normal airport, and it moves a handful of people. You can't scale it up much without scaling up the launch vehicle.
Space X has done something amazing and practical while cutting costs. This looks more like a dead end to me, but I could be wrong.

Starship is also being built for earth air travel, and it’s a ridiculously huge machine that requires a brand new facility anywhere it wants to land in the world. A stratosphere kissing plane makes way more sense
Harnessing the ability of natural killer cells within our own immune system, researchers at Canada’s McMaster University have developed a new form of cancer immunotherapy.
The team engineered natural killer cells to not only attack cancerous cells — including in solid tumors, a problem for some other kinds of immunotherapy — that also to distinguish between those malignant cells and healthy cells that only look like them.

Intriguing indeed, I'm all for curing cancer for people too young to die but it could be a problem if we can't cure long-term conditions such as Dementia, Alzheimer's, Arthritis and nerve damage in old people. Cancer ####ing sucks but for older people sometimes it can end the agony.

One step of a time I guess
we have much more dignified ways of easing people of pain than letting them perish from Cancer.
Now that someone has put in the work to identify the problem, what are the chances that anything is done about it? I would guess only the plant in Germany is altered in any way. That's a bit of a black mark on such an advanced country.

A team from the University of Colorado Boulder, led by Don Grant, Professor of Sociology and Fellow of the Renewable and Sustainable Energy Institute at the University of Colorado Boulder, analyzed the emissions profiles of 29,078 fossil-fuel power plants from 221 countries and found which ones were the “super polluters”.
Quote:
If the top 5 percent of polluters lowered their emission intensity to the global average for fossil fuel plants, the world’s CO2 emissions could drop by 25 percent, the study found.
