For my Son and Daughter:
The 1-foot long by 8-inch tall (30 by 20 cm) engine was built at GE Aviation’s Additive Development Center outside Cincinnati as a side project. The result of several years’ work, the purpose was to test the printing technology. It’s not the first 3D-printed jet engine, but it has been fired and revved up to 33,000 RPM.
GE says that the simplified design was necessary because building anything like a conventional commercial engine is beyond the present technology’s state of the art. The team therefore chose a design created for remote control model planes, which was modified for Direct Laser Metal Melting (DLMM) printing
Engineers at the University of Sheffield’s Advanced Manufacturing Research Center (AMRC), however, have taken things a step farther. They’ve made a 3D-printed UAV airframe that’s designed to minimize the amount of material needed in its construction, and that can be printed and in the air within a single day.

Insanity by the Press (CNN could do hours each week on the horrors of home-made, jet powered, cruise missiles) and faster a knee-jerk from Politicians than a cash donation in a plain envelope.
The two 3-inch-by-1-inch glass chips held the unfathomable amount of genetic information contained in 16 human genomes. On Thursday, a technician placed the chips — called flow cells — in a new genetic sequencing machine at the Genome Institute at Washington University and closed the door.
In just three days, the task will be complete.
It’s mind-boggling given that it took scientists working all over the world more than 10 years and about $1 billion to first sequence the human genome, a feat declared officially complete in 2003.
This ultra-fast sequencing machine, which hit the market last year, is only sold in groups of 10 — a system capable of sequencing 18,000 human genomes a year at just $1,000 to $1,500 per genome.
Which brings us to today’s warp field buzz. Posts on NASASpaceFlight.com, a website devoted to the engineering side of space news, say that NASA has a tool to measure variances in the path-time of light. When lasers were fired through the EmDrive’s resonance chamber, it measured significant variances and, more importantly, found that some of the beams appeared to travel faster than the speed of light. If that’s true, it would mean that the EmDrive is producing a warp field or bubble. Here’s a comment from a space forum following the tests.
BEIJING (AP) – Chinese officials are launching a campaign to crack down on stripteases and other lewd shows that have become popular at funerals in some rural areas, the Ministry of Culture said Thursday.
The ministry said in a statement that it will tighten control over rural culture, where vulgar performances have been thriving because of a general lack of cultural events.
Such erotic performances at funerals are a relatively new phenomenon. Many rural people believe that a large attendance at funerals is a sign of honor for the deceased, and the shows are used to attract more people and display the family’s prosperity.
The funerals also are a rare occasion for crowds to gather as villagers working as migrant workers in industrial centers return home to bury the deceased.
Sounds like a good place to visit and sit for a while.
What made Ada difficult also made it secure and reliable—in simplified programing terms, it was hard to get code past Ada’s exacting compiler, but once you did, it was extremely reliable and resistant to many types of attacks. Could that reliability and security be combined with an easier development path?
When Phil LeClerc, of Weymouth, Massachusetts found this unbelievable Governor Winthrop desk at an auction similar in nature to a yard sale, he was shocked and thrilled that it only cost him $40.
What he found inside was a collection of U.S. savings bonds worth $127,000 in denominations of $500, $1,000 and $10,000. LeClerc immediately did the right thing and returned the desk to the family who had auctioned it off.
It turns out the fortune belonged to a 94-year-old man, who was in need of an assisted living program but could not previously afford it. The man says he lost the bonds many years ago and has been searching for them ever since.
Thank you, Phil LeClerc
A social media company catering to Germany’s adult industry is creating a new position — a sexual position.
Kaufmich.com — which means “buy me” in German — has just announced it is hiring a full-time “prostitute tester.” A willingness to lie down on the job is a requirement, if you get our drift.
The man or woman chosen will review brothels in Germany, emphasizing service, cleanliness and compliance with safe sex practices. Doing this requires having sex with sex workers, according to Kaufmich.com’s product manager, who only gave his name as “Ben” to CNBC.
“Having a brothel in Germany is totally legal but so far there is not a quality system for them in place. We want to be the Tripadvisor for brothels,” Ben told CNBC. “Clients on Kaufmich should be able to check the quality of brothels before there go — like you check your hotel online before you book.”
Two employees at Venezuela’s Vice Ministry of Supreme Social Happiness were far from happy last week when they were fired for refusing to sign a manifesto against the Obama administration, a Caracas-based human rights organization is claiming.
In Petare, a suburb of Caracas, a woman who asked to remain anonymous said she had to step out of a two-hour line to buy fish because she refused to sign the petition, while in the western state of Merida government officials were offering the opportunity to buy milk to those who agreed to support President Nicolas Maduro in his anti-U.S. campaign.
“We also received a case of a worker who was fired for the same reason in Carbonorca [a government-owned company in the state of Bolívar],” said Inti Rodríguez, from the NGO Provea, to Fox News Latino.
Not just Social Happiness but Supreme Social Happiness.
“Ours goes to 11.”
Powers of Ten takes us on an adventure in magnitudes.
Consider the evidence. All those butch pics of ululating young men in sleeveless tees with their guns out. (Both sets!) All that hugging and wailing and attention-seeking… well, you get the idea. Is it just me, or is there something a bit cringe and unconvincing about all that desperate, preening masculinity?
When I see groups of young men huddled on hilltops in Syria, all I can think about is gay club meat markets and the changing rooms at Gold’s. Nowhere is this more evident than when they chuck gays off roofs: as we all know, inside every angry homophobe there’s a Liberace screaming to get out.
Ethereum’s developers believe their project will lead to the proliferation of programs they call “smart contracts,” in which the terms of an agreement are written in code and enforced by software. These smart contracts could carry out the instructions of a complex algorithm based on data feed—such as a stock ticker. They could facilitate practically any financial transaction, such as holding money in escrow or dispersing micropayments among autonomous machines. They could be used to create a peer-to-peer gambling network, a peer-to-peer stock trading platform, a peer-to-peer social network, a prenuptial agreement, a will, a standard agreement to split a dinner check, or a public registry for keeping track of who owns what land in a city.
Transparency and freedom from government busy-bodies. Whats not to like.
Australian researchers have come up with a non-invasive ultrasound technology that clears the brain of neurotoxic amyloid plaques – structures that are responsible for memory loss and a decline in cognitive function in Alzheimer’s patients.
If a person has Alzheimer’s disease, it’s usually the result of a build-up of two types of lesions – amyloid plaques, and neurofibrillary tangles. Amyloid plaques sit between the neurons and end up as dense clusters of beta-amyloid molecules, a sticky type of protein that clumps together and forms plaques.
Publishing in Science Translational Medicine, the team describes the technique as using a particular type of ultrasound called a focused therapeutic ultrasound, which non-invasively beams sound waves into the brain tissue. By oscillating super-fast, these sound waves are able to gently open up the blood-brain barrier, which is a layer that protects the brain against bacteria, and stimulate the brain’s microglial cells to move in. Microglila cells are basically waste-removal cells, so once they get past the blood-brain barrier, they’re able to clear out the toxic beta-amyloid clumps before the blood-brain barrier is restored within a few hours.
The team reports fully restoring the memories of 75 percent of the mice they tested it on, with zero damage to the surrounding brain tissue. They found that the treated mice displayed improved performance in three memory tasks – a maze, a test to get them to recognise new objects, and one to get them to remember the places they should avoid.
Still, I troll Craigslist for an old, beat speedway bike. Still, I look for a steel shoe that might fit my riding boots. Still, I want to get out there and roar alongside some fast guys. I try to explain it to my patient friends. “It’s the Reno Air Races at zero altitude.” I tell them. “It’s Talladega for $2500.” Still, I’m droning about it, and I’m not sure where or when it’ll end. I can’t un-know the experience I’ve had. The bar for thrills is now set at speedway.
What have I learned about riding Hancock’s speedway bike? Almost nothing. I like it. It is entirely unimpressed by me. In this, it’s exactly the same as Vettel’s F1 car. It is perfect at its job and I am not. All flaws were my own, and I took them home with me.
