Humans evolving a spike on the back of the head

Blame smartphones

Humans are evolving a bone spike at the back of the head caused by looking downwards at electronic gear, according to a new study

The spike can be found on the back of your skull, just above your neck and it is believed be caused by your body responding to smartphone use by growing new layers of bone.

In the medical world it is known an external occipital protuberance and David Shahar, a health scientist at the University of The Sunshine Coast, Australia, told BBC.com that in the last decade of his 20-year career he has noticed more patients have the protrusion which was once considered rare.

French scientist Paul Broca first noticed the spike in 1885. However it was rare.

In a study published in the Journal of Anatomy in 2016, Shahar and his co-author described how he had been spotting external occipital protuberances more often in x-rays of relatively young patients at his clinic. To find out more, he looked at 218 radiographs of the lateral cervical spine, where the external occipital protuberance appears, of people aged between 18 to 30-years-old. A growth had to be at least 5mm-long to be counted as an external occipital protuberance, with anything bigger than 10mm classified as enlarged.

Of the group, 41 percent had the lump, with 10 percent having a spike at least 20mm long. It was more common in men than women, at 67 percent versus 20 percent. The longest was 35.7mm in a man and 25.5mm in a woman.

This build-up of bone on the external occipital protuberance is a type of enthesophytes. The bony projection on a tendon or ligament is thought to grow gradually over time, so is not expected in young people. Enthesophytes are relatively common in older people.

Shahar told BBC.com that as we look down at devices like smartphones and tablets, our necks must work to keep our heads in place. Prolonged straining could lead the body to build new bone to increase the surface area, holding up this mass.

In another study published in the journal Scientific Reports in 2018 involving 1200 participants aged between 18 to 86, Shahar's found older people were less likely to have an external occipital protuberance than younger individuals.

Shahar told BBC.com he expects external occipital protuberances to become larger: "Imagine if you have stalactites and stalagmites, if no one is bothering them, they will just keep growing."

How do we know the Milky Way is a spiral? | The Story of the Milky Way

Ever see people wearing those T-shirts with a spiral galaxy on saying "You are here" to mark the position of the Sun? The story of how we figured out the Milky Way was a spiral galaxy and where the Sun was in that big structure, starts all the way back in 1610 with Galileo Galilei...

Can we trust this? I am very sure that the Traveller galaxy is flat because I have the Spinward Marshes sourcebook. There's nothing above or below the map.
 
Exoplanets Discovered In Habitable Zone of Teegarden's Star - 'Only 12.5 Light Years Away'

Teegarden's star is an astronomical oddity, a main sequence star close to the Earth which was undiscovered until 2003. Yesterday a team looking for evidence of exoplanets around small stars revealed observations that suggest 2 planets near this small star. The periods suggest they could be similar to the mass of the Earth and orbiting in a region where the star's light is just right to maintain liquid water.

If the universe is only 14 billion years old, how can it be 92 billion light years wide?

The size and age of the universe seem to not agree with one another. Astronomers have determined that the universe is nearly 14 billion years old and yet its diameter is 92 billion light years across. How can both of those numbers possibly be true? In this video, Fermilab’s Dr. Don Lincoln tells you how.

The UTAS UTS-15 is a 12 gauge pump-action shotgun with two 7-round magazine tubes that can feed in an alternating or selecting pattern. The UTS-15 has a 28.3” overall length with an 18.5” barrel, chambered for 2½”, 2¾”, and 3” magnum ammunition. Constructed primarily of fiber reinforced injection molded polymer, the UTS-15 weighs 6.9 lbs. Additionally, there is a top mounted picatinny rail for the mounting of a wide variety of both iron and optical sights, coupled with Beretta style barrel threading for choke tubes.[1]

Background[edit]
The UTS-15 was developed as a result of a request to UTAS made by Smith & Wesson in 2006 to develop "the ultimate police shotgun". Smith & Wesson's criteria for the shotgun were: 12 Gauge, pump-action, less than 30" overall length, and 13-round minimum capacity.[2]
Features[edit]
The following features are standard on all UTS-15 models:
Bullpup design: pistol grip and trigger are located forward of the barrel breech and action assembly. This allows for the same barrel length as a traditional shotgun but shortens the overall length of the weapon.[3]
Top mounted picatinny rail: allows for the mounting of a wide variety of iron and optical sights.
Twin magazine tubes: set above the barrel to allow for easy access to the loading ports.
Alternating or select tube feed: a selector switch located on the top of the tube/barrel assembly allows for use of multiple ammo types (i.e.: buckshot and birdshot; buckshot and rubber pellets; etc.).
Built-in laser/light controls: the right side of the grip is reserved for controls (a button) for controlling the optional light and laser assembly.
Threaded barrel: Beretta-style barrel threading for choke tubes allows the UTS-15 to be adapted for any situation and a range of attachments.[4]
Accessories and optional equipment for the UTS-15 (as listed by UTAS USA):
Front and rear sight assembly: machined from a solid billet of 7000 series ordinance aluminium with matte black anodized finish these sights are elevation and windage adjustable.[5]
Tactical Choke Tube: machined from 4140 ordinance grade steel and matte black oxide finished. This choke features muzzle spikes and gas ports for breeching. Also considered a choked cylinder it can be used for firing slugs as well as buck shot.[6]
7.5" Barrel Extension: machined from 4140 ordnance grade steel with a matte black oxide finish. This attachment is threaded to screw into the UTS-15 barrel (like the Tactical Choke Tube).[7]
Red Laser/Flashlight Unit: the laser/flashlight unit is specially designed for the UTS-15 shotgun. The flashlight casts a 200 lumen lens focused beam when switched on (using the integrated control button on the grip). The laser is high-intensity and adjustable for both windage and elevation. The machined aluminum housing for the laser/flashlight holds two lithium batteries and is specifically designed to slide into the barrel retaining tube in the lower stock below the barrel where it is held in place by the barrel retaining cap. The UTAS provided set comes with the necessary equipment for mounting the assembly into the shotgun.[8]
Variants[edit]
UTS-15 Desert: features a digitized camo pattern used by both American and NATO forces. Incorporates a desert sand base coat over which the two-color non-glare digital camouflage pattern is applied.[9]
UTS-15 Marine: features a digitized camo pattern which incorporates a marine blue base coat over which the black and gray non-glare digital camouflage pattern is applied. The springs have a corrosion-resistant coating and all exposed metal parts are satin nickel-plated to be resistant to saltwater. All other metal parts, such as the barrel are black chromed or similarly treated to further increase saltwater corrosion resistance.[10]
UTS-15 Hunting: features a hunting-style camouflage pattern.[11]
Critical Reception and Malfunctions[edit]
Due to its unique design the UTS 15 became an easily recognizable weapon within the firearms culture and was reviewed by several different sources. However, over time the UTS 15 became the subject of harsh criticism in the firearms industry developing a reputation for being plagued by numerous malfunctions (primarily failure to feed and failure to extract). UTAS attempted to correct these issues by developing a generation 2 and generation 3 variant of the UTS 15 that were supposed to correct the reliability issue.
 
Dual magazines - tricky to make that work reliably. No surprise they had some issues. Being able to switch between two types of rounds is a nice feature but if it comes with a greater risk of jams or double-feeds...
 
Should be resolved later on.

I notice that some jamming tends to be the result of using ammunition that isn't calibrated exactly to a specific gun model, or sometimes, even the magazine, especially the more complex the mechanism or fine tuned.

With Traveller it tends to be rather generic, but unless some form of certification takes place, using local ammunition might have a similar effect.
 
That was the knock on 30-rd magazines for the M-16 when I was in uniform - prone to feed issues. Presumably they’ve improved since then.

Problems with locally sourced ammunition could be a fun story point in an adventure. Too little (or too much) powder, fouling, even wrong cartridge materials for the environment. Cracking cartridge brass was a classic metallurgical problem a century or more ago. Many copper and brass alloys are susceptible to stress-corrosion cracking in the presence of ammonia, so an atmospheric taint (or storage of cleaning solutions in the ammo cabinet) could lead to similar issues....

Can't say "cool" enough because thats exactly what this thing was made for. I am really glad Trailblazer does not market these as "solving a problem" like some other folding pew companies. They know what they have and own it 👍

More likely first responders, like law enforcement or firemen.

There was a case for it fifty years ago for forward scouting, but this role would now be filled by smaller and cheaper drones.

For Travellers, a bit more endurance, and it would be a rather cheap alternative for air/rafts.
