A group of gunsmiths just 3D printed a bigger, better caliber rifle.

PrintedFirearm.com , a website devoted to 3D printing of guns, announced that one of its members successfully developed a lower receiver for a Colt CM901 rifle. The receiver for the CM901—which is considered to be a much stronger brother of the popular AR-15 assault rifle—was crafted on a XYZ Da Vinci printer, which normally costs around $500 – considered cheap in the 3D printer world. While they were not the first to 3D print a lower receiver, it seems as if Printed Firearm has taken an evolutionary step.

“This is the FIRST EVER 3d Printed AR-10 (CM901/LE901) lower receiver by JT,” reads a blog post on PrintedFirearm.com. “OH YES WE DID!!!!!!! Yes people its pure awesome sauce and it has been tested, fired with little to no issues.”

The CM901 has a similar design to the AR-15 but can fire a heavier and more powerful 7.62 millimeter round, which results in higher range and stopping power. The standard NATO rifle cartridge has a 7.62 mm diameter and a 51 mm case length.

“Is it as strong as metal, no, is it as strong as wood, probably not, is it strong enough to work, yes and it has proven just that.”- PrintedFirearm.com blogger who asked that his name be withheld

The rifle is also a modular weapons system, which allows for multiple modifications, so it is also capable of firing lighter 5.56-millimeter rounds as well.

Printed Firearm posted a five-second GIF of the lower receiver in action at a firing range. Like most 3D printed objects, the part is made from a plastic-like filament so it is not clear how many shots could be fired before it breaks or becomes damaged.

“This receiver is durable enough to work,” The Author of Printed Firearm’s blog, who asked that his name be withheld, told FoxNews.com.  “The reality is the lower receiver in an AR style weapon does not need to be that strong.

“Is it as strong as metal, no, is it as strong as wood, probably not, is it strong enough to work, yes and it has proven just that.”

The blogger adds that the creator of the part claims to have fired over 100 rounds of ammunition without any issues of visible wear and tear.

Blueprints for parts like a lower receiver for the AR-15, have been available on the web to download for several years but this is the first instance where it has been drafted with an affordable printer and has raised the question among some in the community that an affordable rifle — from barrel to stock — will eventually be as simple as hitting the print button.

Others say it will be a long while before that is a reality.

“It’s good for the narrative for the improvements in 3D printing,” Cody Wilson of Defense Distributed, another group that made what was considered the first working 3D printed handgun back in 2013, told FoxNews.Com “But it’s going to be a long time before a rifle can be made on an affordable 3D printer.”

Makeshift gunsmiths have focused mostly on printing lower receivers because it is the only part of the rifle that has federal regulations. Every other part, such as the barrel or the handgrip can be purchased without any sort of permit.

Under current law, there are no federal restrictions on making a gun for personal use – so long as it is under the parameters of both the Gun Control Act and the National Firearms Act.

Officials for the Bureau of Alcohol,Tobacco,Firearms and Explosives told FoxNews.com that they are monitoring developments in 3D printing technology.

“[The] ATF routinely collaborates with the firearms industry and law enforcement to monitor new technologies and current manufacturing trends that could potentially impact the safety of the public,” Dannette Seward, a spokeswoman for the ATF said in a written statement.

Printed Firearm says that the reaction of this latest lower receiver and the low cost will increase the number of hobbyists but would do little in terms of advancing technology.

“At $500 it is something a hobbyist like myself can potentially own,” The blogger said. “The reality is most of us involved in this area of technology are doing it simply to understand what is possible.

“If one wanted to create a stronger, more reliable, item 3D printing would not likely be the best tool to use.”

New study reveals why you shouldn’t drink coffee from a white mug

Think your coffee tastes extra bitter today? You may want to switch mugs.

The color of your cup may be affecting the taste of your morning brew, says a new study released in the online journal Flavour.

The idea for the study was inspired by a barista who overheard customers claiming they thought coffee drunk from a white mug tasted more bitter than drinking from a clear glass container. Researchers conducted a series of experiments where participants drank coffee from white, clear and blue mugs and were then asked to analyze taste.

The study found that coffee drunk from a white cup tastes “significantly more intense”—aka less sweet and more bitter—than drinking from a clear or blue mug.

The reason?

Humans tend to associate color with flavor and white is associated with bitterness. The brown color of the coffee “contrasts” significantly with a white drinking apparatus. Conversely, drinking from a clear cup enhances a drink’s “perceived sweetness.” Blue mugs apparently amplify both sweetness and bitterness, so the brew just tastes stronger overall.

The researchers claim their findings on mug color should “be considered by those serving coffee as it can influence the consumer’s multi-sensory coffee drinking experience.”

Scientists make new discovery about Stone-Age sex

Scientists make new discovery about Stone-Age sex

Scientists are puzzling over a new discovery regarding Stone Age sex: It seems that for every 17 women who reproduced at the time, just one man did the same.

The findings are based on an analysis of the DNA of 450 people from geographically diverse locations. Researchers compared Y-chromosome DNA, which is inherited only from our male forbears, with mitochondrial DNA, which comes from women, Pacific Standard reports.

Such analysis can show experts our numbers of male and female ancestors, and the mystery here is why these ancient numbers are so out of whack.

“It wasn’t like there was a mass death of males,” says Melissa Wilson Sayres of Arizona State University. “They were there, so what were they doing?” Her team has suggested that perhaps a few males accumulated a great deal of wealth, pushing out others when it came to reproduction.

As Danielle Paquette puts it at the Washington Post, “Survival of the fittest might have actually been survival of the richest.” This would have occurred after the dawn of agriculture, suggesting that the top male reproducers were essentially the best farmers.

Amanda Marcotte writes at Slate that the findings would seem to run counter to the thinking of evolutionary biologists who believe our nature was defined during the earlier hunter-gatherer period of cavemen.

She’s also glad that an age in which a few men got all the women is long gone. “That sounds terrible for both men and women.” (Other recent evolutionary research examines why men like curvy women.)

Freedom Bills – Why They Don’t Work…

The problem with protection of groups, religions, speech, gun rights, etc. through legislation is simple – A government that can decide who to protect can also decide who to abuse.  Governments take away rights.  They tell you what you can and cannot do in your life, with your property, with your business, with your money, with your family.

When anyone goes to the government to pass a bill to “protect their rights” they are putting their head in the lion’s mouth.  As Thomas Jefferson wrote in the Declaration of Independence:

“We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.–That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed.”

Our rights and freedoms come from our Creator, not from government.  Governments ONLY get their power from what people give them.  We have given our government too much.  A government big enough to pass your bill today will pass one tomorrow that hurts you.  If we want to treat each other properly, we will.  If we want to discriminate, we will.

There are laws against murder, robbery and fraud.  So those no longer happen right?  In comes Indiana.  It passed a bill similar to federal laws and laws in 20 other states.  It is passed for religious freedom, but is being touted as anti-gay.  Perhaps it is both, perhaps it is neither.  The real issue is, that bill won’t change anything.  I don’t want to drive people underground in their bigotry against religion or bigotry against gays.  I would rather they freely express their opinions so I can choose not to support their businesses.

My prayer is that we can treat each other with love and respect because it is what is right, not keep running to the government to enforce morality.  Think about it for a minute…  Government as a source of morality?  Really?

How You Expose Yourself to Identity Theft with “Fun” Facebook Posts

How You Expose Yourself to Identity Theft with “Fun” Facebook Posts

How often have you seen posts such as, “Find out your rock star name”  Or your “Star Wars name” or “What your personality is?”

They often use your birth month, and day you were born.  You then post this in response.  Some ask about your first pet’s name…  For instance, there was a recent one, your stripper name – Your first pet’s name and the last thing you ate.  There were several posts asking your first concert.

What do these have in common?  They are often used as questions for your bank accounts, passwords, PayPal, computer systems and people use them as passwords.  First pet, month and day of birth, first concert, first car, etc.  These are usually posted by your friends because they think they are fun.  Unfortunately, hackers and identity thieves are the ones that start these “fun” posts that quickly circulate.

identity-theft

You might have much of this information already in your profile.  I won’t say how, but the information in my profile is incorrect.  In fact, the information on all my online profiles are wrong.  When I send in information for magazines and other services, I use different middle initials.  Later, when I get junk mail or phone calls, I can determine who sold my information based on the middle initial used.  The other information is the same.  One of my sisters even asked me why some of my information is wrong.  I told her to please not correct it publicly.

Be aware of this information, posting pictures or names of your kids, posting your address then letting people know you are going to be out on vacation for a week…  All those things are very dangerous for burglary, identity theft and other people looking to do you harm.  The next time you find a “fun” quiz online, just look at the information requested before answering.

2M-year-old find may be ancient ‘playground’

2M-year-old find may be ancient 'playground'

An investigation into what appears to be a nearly 2 million-year-old site in China’s Hebei province suggests the spot served an important purpose: fun. The South China Morning Post compares the dig site to a “playground” for ancient hominids, noting that it was home to some 700 stone objects and 20,000 fragments; some may well have been kids’ toys, believes lead researcher Wei Qi.

He speculates that the objects, most less than two inches long, were made by children and their mothers. “You can almost feel the maker’s love and passion,” says Wei of one piece he describes as “beautifully shaped.” The other bits of evidence supporting his playground theory: The remains of animals or large tools in the area are scarce, suggesting it’s not where hominids lived and a limited number of adults toiled there.

The site is part of the Nihewan basin, which has been the source of a vast trove of ancient discoveries since 1921, Ancient Origins reports.

What’s also relatively new is the dating of the site, carried out by studying its magnetic properties. Results suggesting it dates to between 1.77 million and 1.95 million years ago could make it older than the Dmanisi site in Georgia, which UNESCO calls the “most ancient” in Eurasia.

But outside researchers have their doubts about the playground theory: “It is difficult to rule out the possibility that (the objects) were just stone fragments created by natural forces,” says one.

If the discoveries really were made by hominids more than 1.8 million years ago—when the first hominid is though to have left Africa—it could change the story of human origins, the Week notes.

(A recently discovered jawbone is also challenging such conceptions.)
