SOARescue x Haley Strategic Partners M3 Med Mag Mount

Wednesday, July 28th, 2021

We are proud to introduce the M3 Med mag mount a collaboration between SOARescue & Haley Strategic Partners.

SOARescue is a premier provider of lifesaving equipment and training for the military, law enforcement, and the responsible armed citizen. The M3 is a mounting platform for the low-profile med mag developed by SOARescue.

The Med mag is designed to be the most versatile individual trauma kits available in a small streamline package. IFAKs can get bulky and the genesis of the Medmag came from a need to have a medical kit that could fit in the mag pouch on an officer or soldier. The mount is reloadable with a wide variety of inserts currently offered by SOARescue. If there is a need for a specific type of medical kit you can swap the components within seconds.

The M3 is constructed of laser cut squadron laminate for durability and strength while also having a heavy woven elastic portion for retaining tourniquets, chemlights, sharpies and needle decompression needles.

Get it in Coyote, Black and MultiCam.

Get it at SOARescue or Haley Strategic Partners.

Bird’s-eye View Could be Key to Navigating Without GPS

Wednesday, July 28th, 2021

RESEARCH TRIANGLE PARK, N.C. — A bird’s-eye view may take on new meaning thanks to Army-funded research. Scientists found that a protein in bird’s retinas is sensitive to the Earth’s magnetic field thus guiding its migratory patterns. That finding could be key to Army navigation of both autonomous and manned vehicles where GPS is unavailable.

For decades, scientists have been investigating how animals such as birds, sea turtles, fish and insects sense the Earth’s magnetic field and use it to find their way.

Researchers at the Universities of Oxford and Oldenburg, supported through a co-funded effort of the U.S. Army Combat Capabilities Development Command, known as DEVCOM, Army Research Laboratory and the Office of Naval Research Global, and Air Force Office of Scientific Research were the first to demonstrate that a protein in birds’ retinas is sensitive to magnetic fields and may be a long-sought sensor for biological navigation.

The team discovered that the magnetic sense of migratory birds such as European robins is based on a specific light-sensitive protein in the eye. The research, published in Nature, identified the protein that the scientists believe allows these songbirds to detect the direction of the Earth’s magnetic field and navigate their migration.

“This research not only demonstrated that cryptochrome 4 is sensitive to magnetic fields, but importantly also identified the molecular mechanism underlying this sensitivity,” Dr. Stephanie McElhinny, a program manager at the laboratory. “This fundamental knowledge is critical for informing future technology development efforts aimed at exploiting this mechanism for highly sensitive magnetic field sensors that could enable Army navigation where GPS is unavailable, compromised or denied.”

The researchers extracted the genetic code for the potentially magnetically sensitive cryptochrome 4 and produced the photoactive protein in large quantities using bacterial cell cultures. The team then used a wide range of magnetic resonance and novel optical spectroscopy techniques to study the protein and demonstrate its pronounced sensitivity to magnetic fields.

The team showed that the protein is sensitive to magnetic fields due to electron transfer reactions triggered by absorption of blue light. They believe that these highly-specialized chemical reactions give the birds information about the direction of the Earth’s magnetic field, which acts like a magnetic compass.

“While more research needs to be done to fully understand how cryptochrome 4 senses the weak magnetic field of Earth and how this is ultimately translated into signals that are understood by the migrating bird, this new knowledge is an exciting first step toward potential navigation systems that would rely only on the magnetic field of Earth, unaffected by weather or light levels,” McElhinny said.

Because the magnetic field modifies the cryptochrome protein in a measurable way, cryptochrome proteins or synthetic molecules that mimic the mechanism of cryptochrome’s magnetic sensing could be used in a future navigation device.

Detectable changes in the protein would be decoded to indicate the strength and direction of the magnetic field, and thus the navigational position on Earth.

Proteins like cryptochrome consist of chains of amino acids. Cyrptochrome 4 contains four tryptophan amino acids that are organized in series. According to the research team’s calculations, electrons hop from one tryptophan to the next through the series, generating so-called radical pairs which are magnetically sensitive.

To prove this experimentally, the team from Oldenburg University produced slightly modified versions of the robin cryptochrome, in which each of the tryptophans in turn was replaced by a different amino acid to block the movement of electrons.

Using these modified proteins, the Oxford University chemistry groups experimentally demonstrated that electrons move within the cryptochrome as predicted in the calculations and that the generated radical pairs are essential to explain the observed magnetic field effects.

The team also expressed cryptochrome 4 from chickens and pigeons, which do not migrate. The researchers found that the protein is more magnetically sensitive in the migratory birds than either the chickens or pigeons.

“We think these results are very important because they show for the first time that a molecule from the visual apparatus of a migratory bird is sensitive to magnetic fields,” said Professor Henrik Mouritsen, Institute of Biology and Environmental Sciences at Oldenburg University.

But, he adds, this is not definitive proof that cryptochrome 4 is the magnetic sensor the team is looking for. In all experiments, the researchers examined isolated proteins in the laboratory and the magnetic fields used were also stronger than the Earth’s magnetic field.

“It therefore still needs to be shown that this is happening in the eyes of birds,” Mouritsen said.

Such studies are not yet technically possible; however, the authors think the proteins involved could be significantly more sensitive in their native environment.

In cells in the retina, the proteins are probably fixed and aligned, increasing their sensitivity to the direction of the magnetic field. Moreover, they are also likely to be associated with other proteins that could amplify the sensory signals. The team is currently searching for these as yet unknown interaction partners.

“If we can prove that cryptochrome 4 is the magnetic sensor we will have demonstrated a fundamentally quantum mechanism that makes animals sensitive to environmental stimuli a million times weaker than previously thought possible,” said Peter Hore, professor of Chemistry at the University of Oxford.

Operation in a GPS-denied environment is a U.S. Army goal.

The Army has to be prepared to operate in environments where the technology has been degraded or denied by enemy action, officials said.

In additional to the Army, Navy, and Air Force, the European Research Council also supported this research. The collaboration is also a key part of a Collaborative Research Center funded by the German Research Foundation.

SCUBAPRO SUNDAY – The Men with Green Faces

Sunday, July 25th, 2021

I remember watching this movie/ video more than once when I was getting ready for BUD/S. It was old, but I used it to look for clues on what would happen and what exercises I should be doing to get prepared. I still like to watch it once a year or so just for fun and to help motivate me to stay in shape. Its, also great to hear the guys talk about being quite professional and that they are doing the job for their brother standing next to them and not so they can write a book when they get out. Maybe they should start having people watch it before they start training.

 

Baen Releases “The Family Business: New Novel From Mike Kupari

Sunday, July 25th, 2021

Baen Books has released Mike Kupari’s latest novel, The Family BusinessIt’s a dystopian (perhaps post-apocalyptic*) tale of a Federal “Recovery Agent” on the job in a much-changed United States of America. As of this writing, it is rated 4.4 out of 5 stars on Amazon.

Here’s an excerpt:

THE WEATHER IN PRESCOTT WAS NICE IN THE FALL.

Being both farther south and at a lower elevation, it wasn’t nearly so cold and windy as Flagstaff was in the winter, and in the summer, it didn’t get as hot as it did in the desert around the Phoenix Crater. It was a pleasant morning and Whiskey Row had its share of locals and travelers, even if the bars and brothels weren’t open yet.

Traffic was light. Gasoline and diesel weren’t rationed anymore but were still expensive. Many people walked or rode bicycles to get around, especially on such a nice day. There were even a few folks going about their business on horseback, just like they would have done a hundred years earlier.

*This depends on your definition of catastrophe and apocalypse.

Author Mike Kupari in a deployed location, toiling ceaselessly to improve his skills and weapon manipulation (the better to write much more realistically…).

Kupari, a self-described revolverphile who preaches the Gospel of the FN, is an experienced (though wrong-handed) shooter who uses his experience as a former EOD Technician, PMC contractor, and general retr0-gun-nerd-savant to provide verisimilitude to his writing.

Here’s another excerpt.

REMEMBER PHOENIX

Jesse’s shop looked cluttered and chaotic, but he seemed to know right where everything was. The centerpiece of it was a CNC mill and a lathe. Electronics projects cluttered one workbench, while firearms projects took up another.

A faded Arizona flag hung on one wall, as did a prewar, fifty-star US flag. Next to them was a pair of posters. REMEMBER PHOENIX, one declared, while the other proclaimed KEEP WATCHING THE SKIES!

Below those, framed, was his certificate of his completing the Arizona Ranger training course and a photo of his swearing-in ceremony. Leading Nathan to his gun-bench, Jesse picked up a large pistol and proudly handed it to his friend.

“What’s this?” Nathan asked, examining the gun in his hand. It wasn’t anything he’d seen before, and he knew his way around a gun.

“Did you make this?”

“I did,” Jesse said, beaming. “That’s my third prototype. It’s ready for field testing.”

The gun was a hefty semiautomatic, but the magazine well was located in front of the trigger guard. Nathan locked back the slide, verifying that the weapon was unloaded, and looked at the markings.

“.45 Win Mag?”

Jesse grinned. “Yup! The problem with most magnum semi-autos is that they’re huge, right? It’s because they’re trying to cram a revolver-length, rimmed cartridge into a pistol grip. You end up with a grip like a two-by-four. I solved that by moving the magazine well out of the grip.”

“Like a Broomhandle Mauser,” Nathan said.

“Only in overall layout. This gun is striker-fired. It’s roller-delayed, recoil-operated, like the Kraut STG-88 assault rifle. Try the trigger!”

Nathan released the slide and squeezed the trigger. With only a little bit of take-up, it felt like a thin glass rod breaking.

“Damn.”

“Three and a half pounds’ pull weight on that, and it doesn’t feel mushy. I added a thumb safety because the trigger pull is so light, and to make it extra drop safe. I tossed my second prototype off the roof, onto the driveway, over and over again, trying to get it to discharge, and the safety held.”

“Anyway, the barrel is fixed, so it’s real accurate. For the next prototype, I’m working on a user-serviceable quick-change barrel system. You’ll be able to swap from the five-inch service barrel, like on this one, to a longer, heavier target barrel, and even a short snub barrel. I figure I can machine a scope mount into the heavy barrel, so it’ll be good for handgun hunters. I may be able to figure out a caliber conversion system, eventually, too.”

“This is really nice, Jesse,” Nathan said, aiming the pistol at an antelope head mounted on the wall.

“The magazine holds ten rounds. I’m working on a twenty-rounder, but I haven’t put it together yet. Even still, that’s four extra shots over a typical police revolver, it’s more powerful, and it reloads quicker.”

“I’m impressed, Jesse. Very nicely done. You gonna put these into production?”

“Eh, I really can’t. I’m a one-man outfit. I don’t have the capability to mass-produce a gun and making these as one-offs would make them too expensive. Once I get the design finalized, I’m going to try and sell the manufacturing rights.”

“Yeah, I guess that makes sense.” Nathan flipped the gun around in his hand and offered it to Jesse butt-first. “You gonna pack this beast on your next Ranger call-up?

Kupari The Family Business

Kupari looking OAF in tiger stripe cammies and a Sam Brown wheelgun belt.

The book is officially described thusly:

Decades ago, the Visitors descended on Earth. They claimed to bring peace and prosperity. Their real goal was the total subjugation of humankind. But humanity did not give up its only home without a fight. After a devastating war, the Visitors were driven back to Mars. Their millions of willing human collaborators were left behind. The task of hunting down these former alien collaborators and bringing them to justice falls to Federal Recovery Agents like Nathan Foster.

Now, Nathan Foster is tasked with bringing to justice Emmogene Anderson. As a teenager, Emmogene was experimented on by the Visitors and implanted with a device that allows her to control other people. With her is her obsessive ex-lover, who was also a former commando of the Visitors’ forces. It’s an easy enough job—but Emmogene has been implanted with something else, something much more important.

Nathan and Ben must decide what is right in a largely lawless world— and the fate of the planet hangs in the balance.

Says Kupari,

“I started writing in high school. I didn’t really get into it until college when I began writing fiction online. I never seriously considered trying to be a novelist, though, not until 2006. That was the year I met Larry Correia. He liked a story I was writing online and asked if he could jump in on it. That story ultimately became DEAD SIX.

I lived in Doha, Qatar for a year, while working security at a US installation there. Qatar ultimately became the inspiration for the fictional country of Zubara.

Later in life, I served as an explosive ordnance disposal technician in the US Air Force. I deployed to Afghanistan and applied that experience to my second book, Swords of Exodus.

My first solo novel, Her Brothers Keeper, wasn’t exactly inspired by real life. I am sad to admit that I’ve never captained a privateer rocket ship. I do, however, have a lifelong love of science fiction and space opera and am excited to continue sharing my take on different genres.”
