Oh shit!!  How long has she been in there, man?
What?  I don’t know.  How should I know?  What does it matter?  The best ones are braindead anyway.
Because she’s the boss’ daughter idiot!
Oh shit....
Yeah.  So, how long has she been in there?
I don’t know.  I mean... she came in here nosing around and wanting to know what we were doing down here with all this stuff.  She sounded like a reporter-....
And so you...
Did what the boss says to do to reporters.... Yeah.  We’re fucked, aren’t we...
Nope.  Not we.  You.  You’re the one who did this.
Hey, what’s that supposed to mean?
That maybe I can still salvage this.
Back off man.  What are you planning to... do... with.... that.............. syringe........
Simple.  Knock you out.  Give you to the boss.  And let him finish you off.  But... maybe I’ll wait awhile longer to let you out, little one.   Wouldn’t want you having any memories about how this went down.  Shouldn’t be more than an hour and you’ll be completely blank.  Who knows... maybe the boss will let me write myself a new girlfriend as a reward.  Anyway, we’ve got some time to kill.  So, lets flood the chamber with aphrodesiacs.  Might as well have you give me a show  while we wait.

Well we have some bad news…
A neighbor got their property sprayed for mosquitoes and a good 90% of my bees were killed off. (This is old news to the company who sprayed; we’ve already been through the paces with them and are working towards an agreement. Just wanted to post here so everyone knows what’s up on the bee yard.)

I had to go back through some of the dead out hives to clean them up because hive beetles started growing in them. I’ve already burnt most of the affected comb and set the rest out on the ground for the ants to clear out before I clean and store the boxes. There were LOTS of hive beetle larvae, but they ultimately helped prove the time-frame for when the colonies died.
There are still a couple of hives that survived, albeit with serious casualties. They appear healthy but I’ll definitely be keeping an eye on them. I also have that new swarm, who has settled in nicely to their new home. Hopefully a home devoid of pesticides or other harmful chemicals.

‘Teenage Galaxies’ Are Unusually Hot, Glowing With Unexpected Elements - Technology Org
New Post has been published on https://thedigitalinsider.com/teenage-galaxies-are-unusually-hot-glowing-with-unexpected-elements-technology-org/
‘Teenage Galaxies’ Are Unusually Hot, Glowing With Unexpected Elements - Technology Org
Like human teenagers, teenage galaxies are awkward, experience growth spurts and enjoy heavy metal — nickel.

A Northwestern University-led team of astrophysicists has just analyzed the first results from the CECILIA (Chemical Evolution Constrained using Ionized Lines in Interstellar Aurorae) Survey. This program uses NASA’s James Webb Space Telescope (JWST) to study the chemistry of distant galaxies.  
According to the early results, so-called “teenage galaxies” — which formed two-to-three billion years after the Big Bang — are unusually hot and contain unexpected elements, like nickel, which are notoriously difficult to observe.  
The research was published today (Nov. 20) in The Astrophysical Journal Letters. It marks the first in a series of forthcoming studies from the CECILIA Survey. 
“We’re trying to understand how galaxies grew and changed over the 14 billion years of cosmic history,” said Northwestern’s Allison Strom, who led the study. “Using the JWST, our program targets teenage galaxies when they were going through a messy time of growth spurts and change. Teenagers often have experiences that determine their trajectories into adulthood. For galaxies, it’s the same.” 
One of the principal investigators of the CECILIA Survey, Strom is an assistant professor of physics and astronomy at Northwestern’s Weinberg College of Arts and Sciences and a member of Northwestern’s Center for Interdisciplinary Exploration and Research in Astrophysics (CIERA). Gwen Rudie, a staff scientist at Carnegie Observatories, co-leads the CECILIA Survey with Strom.
‘Chemical DNA’ gives insight into galaxy formation 
Named after Cecilia Payne-Gaposchkin, one of the first women to earn a Ph.D. in astronomy, the CECILIA Survey observes spectra (or the amount of light across different wavelengths) from distant galaxies.  
“Naming our JWST survey after Cecilia Payne-Gaposchkin was intended to pay homage to her pioneering studies of the chemical makeup of stars,” Rudie said. “Allison and I recognize that our own work revealing the chemistry of these very early galaxies is built upon her legacy.” 
Strom likens a galaxy’s spectra to its “chemical DNA.” By examining this DNA during a galaxy’s “teenage” years, researchers can better understand how it grew and how it will evolve into a more mature galaxy.
For example, astrophysicists still don’t understand why some galaxies appear “red and dead” while others, like our Milky Way, are still forming stars. A galaxy’s spectrum can reveal its key elements, such as oxygen and sulfur, which provide a window into what a galaxy was previously doing and what it might do in the future. 
“These teenage years are really important because that’s when the most growth happens,” Strom said. “By studying this, we can begin exploring the physics that caused the Milky Way to look like the Milky Way — and why it might look different from its neighboring galaxies.” 
In the new study, Strom and her collaborators used the JWST to observe 33 distant teenaged galaxies for a continuous 30 hours this past summer. Then, they combined spectra from 23 of those galaxies to construct a composite picture. 
“This washes out the details of individual galaxies but gives us a better sense of an average galaxy. It also allows us to see fainter features,” Strom said. “It’s significantly deeper and more detailed than any spectrum we could collect with ground-based telescopes of galaxies from this time period in the universe’s history.”  
Spectra surprises 
The ultra-deep spectrum revealed eight distinct elements: Hydrogen, helium, nitrogen, oxygen, silicon, sulfur, argon and nickel. All elements that are heavier than hydrogen and helium form inside stars. So, the presence of certain elements provides information about star formation throughout a galaxy’s evolution.
“JWST is still a very new observatory,” said Ryan Trainor, an associate professor of physics at Franklin & Marshall College and one of the paper’s co-authors. “Astronomers around the world are still trying to figure out the best ways to analyze the data we receive from the telescope.”
Light from 23 distant galaxies, identified with red rectangles in the Hubble Space Telescope image at the top, were combined to capture incredibly faint emission from eight different elements, which are labelled in the JWST spectrum at the bottom. Although scientists regularly find these elements on Earth, astronomers rarely, if ever, observe many of them in distant galaxies. Image credit: Aaron M. Geller, Northwestern, CIERA + IT-RCDS
While Strom expected to see lighter elements, she was particularly surprised by the presence of nickel. Heavier than iron, nickel is rare and incredibly difficult to observe. 
“Never in my wildest dreams did I imagine we would see nickel,” Strom said. “Even in nearby galaxies, people don’t observe this. There has to be enough of an element present in a galaxy and the right conditions to observe it. No one ever talks about observing nickel. Elements have to be glowing in gas in order for us to see them. So, in order for us to see nickel, there may be something unique about the stars within the galaxies.”  
Another surprise: The teenage galaxies were extremely hot. By examining the spectra, physicists can calculate a galaxy’s temperature. While the hottest pockets with galaxies can reach over 9,700 degrees Celsius (17,492 degrees Fahrenheit), the teenage galaxies clock in at higher than 13,350 degrees Celsius (24,062 degrees Fahrenheit). 
“This is just additional evidence of how different galaxies likely were when they were younger,” Strom said. “Ultimately, the fact that we see a higher characteristic temperature is just another manifestation of their different chemical DNA because the temperature and chemistry of gas in galaxies are intrinsically linked.”

In 2003, Archaeologist Sergio Gomez was walking by the Temple of Quetzalcoatl, when he noticed a large crack in the ground approximately 20 feet (six meters) from the foot of the stairs. Recent rains had opened a surface area, leaving a noticeable divot and exposing tourists to possible injury.
