Nah, he'd be Tweeting about buying unobtainium from them to make the most amazing wall, and promising that Americans will get jobs manning the hyperspace craft that transport the metal.

Nah. He's been trumpeting the Saudi arms deal (and getting crap about it) when the ink isn't even on paper, much less dry. The fucker has no goddamned filter.

In 2009, NASA's ARCADE mission sent radiometers to an altitude of 120,000 feet to do radio astronomy outside the Earth's atmosphere. To the mission planners' surprise, the level of radio noise was six times higher than anyone had predicted, and nobody has any idea where it might be coming from.
Many objects in the universe emit radio waves. In 1931, American physicist Karl Jansky first detected radio static from our own Milky Way galaxy. Similar emission from other galaxies creates a background hiss of radio noise.

The problem, notes team member Dale Fixsen of the University of Maryland at College Park, is that there don't appear to be enough radio galaxies to account for the signal ARCADE detected. "You'd have to pack them into the universe like sardines," he says. "There wouldn't be any space left between one galaxy and the next."

https://www.nasa.gov/centers/goddard/ne ... lloon.html
I bet it's the sun.
One assumes that a solar signal would be directional enough that it could be identified as the source of said noise. I'm guessing that the space roar in question is omnidirectional (if that's the right term to use for an incoming signal, rather than an antenna configuration). Like the cosmic microwave background, it's a signal that's coming from everywhere at once. This is, however, speculation without even RingTFA.
Yeah I'm occamming they did something stupid.

Freakish xenotransplantation experiments: if you transplant antlerogenic periosteum (basically, antler-growing tissue) from deer into mice, the mice start growing antler-like protuberances. (Not full-fledged antlers, so don't get too excited.) Given that antlers can grow up to 3/4" per day, some researchers think they might hold secrets to understanding how to encourage tissue regeneration.

Nature has already been experimenting with this for years. I've got the postcards to prove it.

I don't know enough to know if this is a particularly ground-breaking piece of work on gravity, but I do know that it's a piece of precision measurement done in China and accepted by a good US journal. And in the not-too-distant past that would have been unthinkable.

https://journals.aps.org/prl/abstract/1 ... 121.261101

China has gone a long way to improve their reputation for high-precision technical work, and we're going to see effects from that in industry as well as academia. In the US, the sorts of people who get their PhD for work like this tend to be recruited into high-tech industries that value precision.

I'm thinking that would be a new reputation for Chinese engineers. The thing the Chinese are most known for is making substandard stuff.

Since China now manufactures a huge portion of the world's tech gadgets, I am wondering how recently you heard that.

Whatever you think about sex/gender in athletics, transgender identity, etc., people with sexual anomalies show a remarkably rich variety of phenotypes and capabilities. Here's a case of an XY woman who gave birth without any difficulties, and whose daughter is also an XY woman:

https://academic.oup.com/jcem/article/93/1/182/2598461

Separate from the question of what, if anything, should be done concerning intersex of otherwise sexually complicated people competing in women's sports, the whole phenomenon is just interesting on a scientific level. The 0.02% of humans who don't fit into the sexual binary (not to be confused with the gender binary) show remarkably rich variation.

Scientists have long used the ratio of finger lengths as a proxy for prenatal exposure to anomalous levels of sex hormones. That practice is now under scrutiny, and may or may not fall victim to the replication crisis:

This sounds fascinating, although I'm not even sure I quite understand it. It's basically a passive cooling device that works by absorbing heat from the air and then emitting heat as a narrow beam through the atmosphere?

I am moderately skeptical as it seems to take energy from a low level and concentrate it without some sort of power to drive the exchange.

It seems to me the net cooling - which is only net over whatever a roof would absorb from the sun without it - is to basically 'shade' the sun during the day, reducing absorption, so that the max black body emittance overnight gives off more heat than what was absorbed.
