The Navy Says UFOs Are Real. UFO Hunters Are Thrilled – VICE

With the Navy’s recent revelation that its pilots have been regularly spotting unidentified flying objects, some of those in the UFO community who were once thought crazy now have some concrete evidence to point to. And the regular spate of mainstream news stories about UFO sightings has inspired a new generation of UFO hunters and researchers.

I’m regularly asked why I, a 32-year-old man with a good job and a young family spent six years researching the UFO subculture. Simply put, I find the culture and the people fascinating.

Ufology has always been a counter-cultural movement. Faced with decades of ridicule, the UFO community has always been the underdog. I like underdogs. But unidentified flying objects have made a cultural comeback, and the last two years have seen a huge growth in popular media coverage of this curious phenomenon and the people who explore it. It seems that UFOs have become all the rage, and this popular resurgence is inspiring a young new breed of UFO researchers and hunters.

Florida sewage pipes feed fish and pollute beaches.

Ten feet before us, a sewer pipe made out of limestone spews yellow-brownish insults into the reef ecosystem. The pipe’s mouth is barely visible through the cluster of baitfish and foragers, a silver mass of twitch and glide binging on nutrients long processed and evacuated by Broward County taxpayers. A goliath grouper bullies its way through and enters the pipe to feed. I’m told to watch out for fishing lines—an entanglement hazard for the sub’s thrusters. The Hollywood outfall pipe serves as a popular fishing spot, toilet to table.

Recordings by Elton John, Nirvana and Thousands More Lost in Fire – The New York Times

This is astonishing. As an IT guy, I have been responsible for backups. How Universal could be so careless with priceless audio tapes just boggles my mind.

Eleven years ago this month, a fire ripped through a part of Universal Studios Hollywood.

At the time, the company said that the blaze had destroyed the theme park’s “King Kong” attraction and a video vault that contained only copies of old works.

But, according to an article published on Tuesday by The New York Times Magazine, the fire also tore through an archive housing treasured audio recordings, amounting to what the piece described as “the biggest disaster in the history of the music business.”

Don’t Panic about Rare Earth Elements – Scientific American

As trade tensions rise between the U.S. and China, rare earth minerals are once again in the political spotlight. Today Chinese mines and processing facilities provide most of the world’s supply, and Chinese leader Xi Jinping has hinted about using this as political leverage in trade negotiations with U.S. President Donald Trump’s administration. But in the long run, many experts say the global market involving these materials would likely survive even if China completely stopped exporting them.

Cheap Thoughts: flash magnetism

Wouldn’t it be cool if you could “flash magnetize” ferrous metal? Put a current or magnetic field into something, magnetize it, remove power/field and STILL have it be magnetic? And more importantly, demagnetize it instantly. Passive electromagnetism. I know you can impart magnetism into certain things but how strongly can this be done?

This may all be simple stuff to others, I don’t know. It’s been a while since I’ve played with magnets and motors so I’ve forgotten a lot. Seems useful to have an electromagnet which only uses electricity to change its state.

Update: This is exactly what I need: an Electropermanent magnet. Interesting!

New teeth – invisible aligners

For the past few years I’ve been getting a chip in my front tooth patched by my dentist. This patch will last anywhere between 8 months to as short as one hour before it pops off and I have to get it done again. I’m not a fan of the look of this chipped tooth but I can’t keep getting it patched, either. My dentist, recommended I get orthodontics to help keep my teeth from smacking together and dislodging the patch.

The orthodontist recommended by my dentist put a hefty price tag on moving my teeth and I just couldn’t justify the cost. I put that on hold before I checked out Smile Direct Club (SDC). SDC would use the same invisible aligners (InvisAlign) that the orthodontist would use but the cost would be less than two-thirds the price. The downside is I wouldn’t receive personal care from an orthodontist. I decided to go for it, since I have had three years of orthodontics experience as a teenager and know what to expect.

So far, it’s been so good. I put in my first aligners a week ago Saturday and began my second one this past Saturday. My teeth ached a bit for most of the first week but by that Wednesday I felt comfortable enough wearing them that I didn’t mind them anymore. There’s no question that my teeth have shifted in the 9 days I’ve worn the aligners, so I have no doubt that they’re working. And I’ve become a bit obsessed with wearing them.

New York Times story focused on Raleigh gentrification | Raleigh News & Observer

Ned Barnett’s opinion piece last week, downplaying the damaging effects of gentrification, was incredibly tone-deaf.

Indeed the Times story called attention to the implication that there is something wrong with downtown neighborhoods gaining new homes and more value as white flight reverses.

Well, yes, yes there is. There is something wrong with it, Ned. Surging property values are great for owners, unless those owners are unable to pay the soaring property taxes. Surging property values aren’t too fun for the renters who get pushed out by skyrocketing rents or by the flipping of homes.

We can improve neighborhoods without pushing out the long-time residents – the people who actually contribute to the character of any neighborhood. The question we should be asking is: how can everyone benefit from prosperity?

Raleigh is now almost blase about being cited in the national media as a city on the rise, but a New York Times report last week cast that growth in a less flattering light. It used Raleigh as exhibit No. 1 of how well-off whites are moving into traditionally black neighborhoods near urban centers and converting longtime nonwhite areas into white enclaves.

The story stressed that Raleigh’s pattern is part of a national trend, but its focus in photos, videos and quotes was on North Carolina’s capital. The theme was that poorer blacks are being pushed out and those who remain feel their neighborhood is being usurped.

The coverage put a spotlight on an issue Raleigh’s leaders know about but have not directly addressed: How much should growth be allowed to displace residents and transform neighborhoods?

Something in the blood – ME/CFS Research Review

Fluge and Mella used an expensive bit of kit called the Seahorse analyser, which measures glycolysis through the lactate production and mitochondrial activity through changes in oxygen levels.

They tested normal healthy muscle cells that had been grown in the lab. But they added to those cells serum taken from either ME/CFS patients or healthy controls. Serum is the fluid left over after blood has clotted and it contains small molecules and other soluble substances.

They have data for 12 people with ME/CFS and 12 healthy controls, a relatively small sample.What they found was, surprisingly, that the muscle cells produced more lactate and burned more oxygen when they were incubated with ME/CFS serum than when incubated in serum from healthy controls. And the effect was particularly strong when the cells were made to work hard.

The Neighborhood Is Mostly Black. The Home Buyers Are Mostly White. – The New York Times

A sobering read on gentrification of downtown Raleigh from the New York Times.

RALEIGH, N.C. — In the African-American neighborhoods near downtown Raleigh, the playfully painted doors signal what’s coming. Colored in crimson, in coral, in seafoam, the doors accent newly renovated craftsman cottages and boxy modern homes that have replaced vacant lots.

To longtime residents, the doors mean higher home prices ahead, more investors knocking, more white neighbors.

Here, and in the center of cities across the United States, a kind of demographic change most often associated with gentrifying parts of New York and Washington has been accelerating. White residents are increasingly moving into nonwhite neighborhoods, largely African-American ones.
