Video below the fold. The gun clearly functions, though I noticed that in the video they never loaded more three rounds in a magazine, and that the gun seems to cycle weakly. I suspect that they had some feeding problems when they tried to fire a full loaded five round magazine.

Nonetheless, this achievement further illustrates that 3D printing is about to become a major method of manufacture.

Genesis cover

On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.

 

The print edition can be purchased at Amazon, any other book seller, or direct from my ebook publisher, ebookit. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.


The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
 

"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

Successfully growing crops in the desert using salt water and solar power.

Successfully growing crops in the desert using salt water and solar power.

The heart of the SFP concept is a specially designed greenhouse. At one end, salt water is trickled over a gridlike curtain so that the prevailing wind blows the resulting cool, moist air over the plants inside. This cooling effect allowed the Qatar facility to grow three crops per year, even in the scorching summer. At the other end of the greenhouse is a network of pipes with cold seawater running through them. Some of the moisture in the air condenses on the pipes and is collected, providing a source of fresh water.

One of the surprising side effects of such a seawater greenhouse, seen during early experiments, is that cool moist air leaking out of it encourages other plants to grow spontaneously outside. The Qatar plant took advantage of that effect to grow crops around the greenhouse, including barley and salad rocket (arugula), as well as useful desert plants. The pilot plant accentuated this exterior cooling with more “evaporative hedges” that reduced air temperatures by up to 10°C. “It was surprising how little encouragement the external crops needed,” says SFP chief Joakim Hauge.

The technology development here is wonderful, but it is unclear from the article whether these crops would be competitive on the open market with ordinary farm crops. The cost for this operation is not outlined.

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

 

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.

The number of candidate exoplanets found by Kepler has now risen to 3,500.

Worlds without end: The number of candidate exoplanets found by Kepler has now risen to 3,500.

According to this new analysis, researchers estimate about 70% of stars are host to at least one planet, making planets a common cosmic occurrence. There are now 1,750 candidates that are super-Earth-size or smaller, and 1,788 are Neptune-size or larger. Only 167 of the 3,538 candidates are confirmed to be planets, but Kepler has a good track record: the vast majority of these are probably real.

Two dozen of these candidates are in the habitable zone, ten of which are thought to be close to Earth-sized.

Hubble spots an asteroid spout six comet-like tails.

Hubble spots an asteroid spout six comet-like tails.

Astronomers viewing our solar system’s asteroid belt with NASA’s Hubble Space Telescope have seen for the first time an asteroid with six comet-like tails of dust radiating from it like spokes on a wheel. Unlike all other known asteroids, which appear simply as tiny points of light, this asteroid, designated P/2013 P5, resembles a rotating lawn sprinkler. Astronomers are puzzled over the asteroid’s unusual appearance.

A rare new microbe has been found in two different clean rooms, one in Florida and the other in South America.

A rare new microbe has been found in two different clean rooms, one in Florida and the other in South America.

This population of berry-shaped bacteria is so different from any other known bacteria, it has been classified as not only a new species, but also a new genus, the next level of classifying the diversity of life. Its discoverers named it Tersicoccus phoenicis. Tersi is from Latin for clean, like the room. Coccus, from Greek for berry, describes the bacterium’s shape. The phoenicis part is for NASA’s Phoenix Mars Lander, the spacecraft being prepared for launch in 2007 when the bacterium was first collected by test-swabbing the floor in the Florida clean room.

Some other microbes have been discovered in a spacecraft clean room and found nowhere else, but none previously had been found in two different clean rooms and nowhere else. Home grounds of the new one are about 2,500 miles (4,000 kilometers) apart, in a NASA facility at Kennedy Space Center and a European Space Agency facility in Kourou, French Guiana.

Unlike the bacteria found on ISS, this microbe does not appear to pose any specific health problem. It does provide biologists with a good example of the kind of life that might survive in hostile environments like Mars.

The accumulated evidence from the Chelyabinsk meteorite now suggests the risk of large asteroid impacts might be ten times greater than previously estimated.

The accumulated evidence from the Chelyabinsk meteorite now suggests the risk of large asteroid impacts might be ten times greater than previously estimated.

The Chelyabinsk asteroid had approached Earth from a region of the sky that is inaccessible to ground-based telescopes. In the 6 weeks before the impact, it would have been visible above the horizon only during the daytime, when the sky is too bright to see objects of its size, says Borovička.

“The residual impact risk — from asteroids with yet-unknown orbits — is shifting to small-sized objects,” says Peter Brown, a planetary scientist at the University of Western Ontario in London, Canada, and an author on the Nature papers.

Of the millions of estimated near-Earth asteroids 10–20 metres in diameter, only about 500 have been catalogued. Models suggest that an object the size of the Chelyabinsk asteroid hits Earth once every 150 years on average, Brown says. But the number of observed impacts exceeding 1 kiloton of TNT over the past 20 years alone hints at an actual impact risk that may be an order of magnitude larger than previously assumed,

The data also now suggests that the Chelyabinsk asteroid was twice as big as previously thought, and that it had an almost identical orbit to a much larger already known asteroid.

A new ligament has just been discovered in the human knee.

A new ligament has just been discovered in the human knee.

[T]he Belgian doctors are the first to identify the previously unknown ligament after a broad cadaver study using macroscopic dissection techniques. Their research shows that the ligament, which was given the name anterolateral ligament (ALL), is present in 97 per cent of all human knees.

This only illustrates once again that as much as we think we know, there is always something new to discover.

A man in New Mexico was illegally subjected to a cavity search, including a colonoscopy, without his permission and without a legal warrant as the result of a simple traffic stop.

A man in New Mexico was illegally subjected to a cavity search, including a colonoscopy, without his permission and without a legal warrant as the result of a simple traffic stop.

As he was being detained and probed, Kennedy said Eckert never gave doctors his consent to perform the procedures and protested his treatment, which all arose from the simple traffic violation. The entire ordeal lasted for roughly 12 hours. TheBlaze has reached out to the Deming Police Department. This story will be updated should the department respond. ,,,

Kennedy [the man’s lawyer] also said the search warrant — in which there were legal concerns anyway — was carried out illegally because it was only valid in Luna County, N.M. The anal cavity search and other procedures were performed at the Gila Regional Medical Center, in Grant County. Further, she said the search warrant was only good through 10 p.m., but medical records show the preparation for the colonoscopy started at 1 a.m. the next morning. In theory, even if the search warrant were completely legal and compliant, it was no longer valid.

The man is suing the city of Deming, New Mexico, the specific officers who detained him, as well as the medical center and the doctors who performed the procedures against his will. I hope their careers are destroyed by this horrible act.

A new study suggests that the variation of the cosmic ray flux during the solar cycle has little influence on the climate.

The uncertainty of science: A new study suggests that the variation of the cosmic ray flux during the solar cycle has little influence on the climate.

The study seems statistical in nature, which leaves me skeptical. Nonetheless, the link between cosmic rays and climate change remains tenuous, with only one study at CERN providing any evidence that cosmic rays might have an influence.

The sun goes boom!

It is always best to admit when you are wrong as soon as you find out. Last month, in reporting NOAA’s monthly update of the solar cycle, I unequivocally stated that

My interpretation of this data tells me that almost certainly the solar maximum has ended. We might see some later fluctuations whereby the sunspot number jumps, but the Sun is clearly beginning its ramp down to solar minimum.

Well, I spoke too soon. Last night NOAA posted the newest update of the solar cycle, and it shows that in October the Sun was more active then it has been in two years. In fact, for only the second time this entire solar cycle the Sun’s sunspot activity actually came close to matching the predictions of scientists. This month’s graph is posted below the fold, with annotations.

Obama now just learning that he is President!

Heh. Obama now just learning that he is President!

“I mean, I knew I was in a position of high importance, but not like THE President and all. I’m just as shocked as you all!” said the President to reporters in the White House’s Rose Garden, Monday. “…A lot of people have been wondering how all these scandals and things could be happening under my watch and I not know about it…” Obama said. “Well, when you don’t know you’re in charge of all these agencies and people, how can you? Think about it. It’s not my fault.”

Read it all. I especially like his response to a gentle and supportive question from a CNN reporter.

‘This thing has legs.’”

“‘This thing has legs.’”

“One thing that politicians caught in a firestorm such as the current one swirling around the president’s health-care plan can hope for is that the thing will quickly die down once the news value is exhausted,” Hume said. “Unfortunately for the president, that does not seem to be happening. First came the website fiasco, then the stories of hundreds of thousands of policy cancellations. That’s now followed by reports of people losing their doctors as well. Incidents are now beginning to surface of people who managed to log on to the Obamacare website, being shocked at the prices of available health plans or the size of deductibles, or both.”

In the last few days I have been reminded increasingly of the problems Nixon had during his Watergate scandal. Instead of hitting the news in one big swoop, Watergate dribbled out over years, and that slow dribble was what kept it in the news long enough for the entire population to eventually get educated about it. More than anything else, that was what destroyed Richard Nixon.

Obama has had numerous scandals during his five years in office. None has damaged him seriously, because each popped up quickly and than faded as fast (mostly due to the willingness of a loyal press to protect him). With Obamacare, however, that can’t happen. Step-by-step, this disaster of a law is going to impose itself badly on Americans, and every time it does, the lies Obama and the Democrats told to get it passed are going to once again be highlighted. This is Nixon all over again, and it is going to do incredible damage to the Democratic Party come election time.

Students crash rockets into the ground on purpose! With video.

Students crash rockets into the ground on purpose! With video.

In what at first glance seems like a terrible sense of direction, in March students from the University of Washington fired rockets from kites and balloons at an altitude of 3,000 ft (914 m) straight into the ground at Black Rock, Nevada: a dry lake bed in the desert 100 mi (160 km) north of Reno. This may seem like the ultimate in larking about, but it’s actually a serious effort to develop new ways of collecting samples from asteroids.

For its next science mission the European Space Agency (ESA) has now decided to give first priority to an X-ray space telescope.

For its next science mission the European Space Agency (ESA) has now decided to give first priority to an X-ray space telescope.

They have demoted a space-based gravity wave detector to second place. As is typical for ESA, the pace here is quite slow, as both missions are now scheduled for launch in 2028 and 2034, decades away.
