Read part 2 of the New York Times article. No video of the maneuverability, but apparently the account from the military is that it would hover at 80,000 feet, then drop to 20,000, then shoot right back up again at an incredible speed. I am not sure if this video is the same object, but if it is, there is nothing known to the public that could possibly do this.
Sounds like one of those reflection UFO's you sometimes see in your car window, man they're fast!
Without physical evidence I just can't wrap my head around how any living thing could survive a trip through interstellar space, the distances are unimaginable and probably totally impossible.
I suppose we may have been visited by alien probes that could be thousands or even millions of years old and got here by fluke or is programmed to look for a water planet or something like that but again, without physical evidence it's just fog to me

Not sure if you have read this yet but here is an interesting account of some F/A-18 pilots and Navy ships tracking an object by radar and eyes on visual after being deployed to the objects location. What is described is an AAV that is seen and recorded as being able to achieve such movement and speeds.
What Dave didn’t know was for the past several days, Princeton had been picking up some bizarre returns on their Death Star-worthy SPY-1 radar. On several occasions beginning 10 November, the Fire Control Officer and the extremely experienced Fire Control Senior Chief had detected multiple returns descending from far above the radar’s scan volume–somewhere higher than 80,000 ft. The targets, dubbed Anomalous Aerial Vehicles (AAVs), would drop from above 80K to hover roughly 50 feet off the water in a matter of seconds.
I enjoy UFO talk/theory, but certainly is not 'important science news'.
The U.S. military funding a space object identification program and providing video evidence of things they have encountered, while disclosing (for the first time in their history) this type of information isn't science-related news?
What is it then?

If you guys love discussions about the future of AI, robots, human evolution to machines, etc.. Then check this discussion out, the whole discussion is excellent but if you want to specifically listen to the AI part start at 1hr 36 minutes.

Ironic discussion kind of, in that at one point they're talking about the risks of having media misrepresenting the truth online while at the same time their discussion comes across as a pretty poorly informed discussion of AI.
If you want a shorter and more reality-driven video something like this is better:
Or just go listen to talks by Kurzweil or others from Singularity University directly for better futurist thinking.

A breakthrough that may replace cobalt with iron ore in rechargeable batteries.
“Because there is only one lithium ion per one cobalt, that limits of how much charge can be stored. What’s worse is that current batteries in your cell phone or laptop typically only use half of the lithium in the cathode.”
The [Northwestern] fully rechargeable battery starts with four lithium ions, instead of one. The current reaction can reversibly exploit one of these lithium ions, significantly increasing the capacity beyond today’s batteries. But the potential to cycle all four back and forth by using both iron and oxygen to drive the reaction is tantalizing.
“Four lithium ions for each metal — that would change everything,” Wolverton said. “That means that your phone could last eight times longer or your car could drive eight times farther. If battery-powered cars can compete with or exceed gasoline-powered cars in terms of range and cost, that will change the world.”

We seem to get news of new battery breakthroughs every few months, but nothing ever seems to actually become commercially viable. I've stopped getting my hopes up

No kidding. I'm still waiting for the promised 10x increase in energy density for a battery pack.

How alcohol damages DNA and increases cancer risk
Date:
January 3, 2018

Summary:
Scientists have shown how alcohol damages DNA in stem cells, helping to explain why drinking increases your risk of cancer, according to new research.
Such breakthroughs in any field are rare. Energy density and cost of batteries has improved dramatically over the last 30 years.
Fair, but that is precisely what is needed to put EVs on par with ICEs.
Simply put, the energy density of current tech battery packs needs to increase by a factor of 10 to equal gasoline.
The troubling thing for me is that there isn't a non-portable form of battery storage that can come close to competing with a combustible energy source.
The Tesla grid storage in Australia is looking hopeful, but it is little more than proof of concept at this stage.

Battery tech doesn't have to get 10 times better to make the ICE car obsolete. I'd say 2-3x, with faster charging times. When that happens (and it will) there will be almost no reason to own a fuel burner.
My favourite energy storage system is water, although it won't work in all areas. It works by using excess solar generated power to pump water uphill, at night it drains down and runs generators. With some creativity the system can be integrated into the surroundings so you'll hardly know it exists. I dislike wind farms, a lot. Battery farms seem to work very well and are modular so repairs and downtimes are not an issue.
