If so, you’re not alone, as the quest for a better energy existence has been the focus of many ingenious inventors, scientists, experimenters and even corporate and government scientists for generations.We know it’s possible, but for some reason, though, society just can’t seem to get b [...]
Catherine J. Frompovich, GuestTalk about copycats! Whoa! Someone did a rather convincing job of that, I’d say. It’s the Internet site “Domestic Surveillance Directorate. Defending Our Nation. Securing The Citizen,” which identifies itself as a “parody” on the NSA (National Security Agency). The parody site does an excellent job, so I encourage readers to study it thoroughly, as it contains too much information to talk about here [...]

With the right expertise in molecular biology, one could start a basic laboratory to modify human embryos using a genome-editing computer technique all for a couple thousand dollars, according to a new report.
Genetic modification has received heightened scrutiny recently following last week’s announcement that Chinese researchers had, for the first time, successfully edited human embryos’ genomes.
The team at Sun Yat-Sen University in Guangzhou, China, used CRISPR (clustered regularly interspaced palindromic repeats), a technique that relies on “cellular machinery” used by bacteria in defense against viruses.
This machinery is copied and altered to create specific gene-editing complexes, which include the wonder enzyme Cas9. The enzyme works its way into the DNA and can be used to alter the molecule from the inside. The combination is attached to an RNA guide that takes the gene-editing complex to its target, telling Cas9 where to operate.
Use of the CRISPR technique is not necessarily relegated to the likes of cash-flush university research operations, according to a report by Business Insider.
"You could conceivably set up a CRISPR lab for $2,000,” he said, according to Business Insider.
Other top researchers have echoed this sentiment.
"Any scientist with molecular biology skills and knowledge of how to work with [embryos] is going to be able to do this,” Jennifer Doudna, a biologist at the University of California, Berkeley, recently told MIT Tech Review, which reported that Doudna co-discovered how to edit genetic code using CRISPR in 2012.
Last week, the Sun Yat-Sen University research team said it attempted to cure a gene defect that causes beta-thalassemia (a genetic blood disorder that could lead to severe anemia, poor growth, skeletal abnormalities and even death) by editing the germ line. For that purpose they used a gene-editing technique based on injecting non-viable embryos with a complex, which consists of a protective DNA element obtained from bacteria and a specific protein.
"I suspect this week will go down as a pivotal moment in the history of medicine," wrote science journalist Carl Zimmer for National Geographic.
Response to the new research has been mixed. Some experts say the gene editing could help defeat genetic diseases even before birth. Others expressed concern.
“At present, the potential safety and efficacy issues arising from the use of this technology must be thoroughly investigated and understood before any attempts at human engineering are sanctioned, if ever, for clinical testing,” a group of scientists, including some who had worked to develop CRISPR, warned in Science magazine.
Meanwhile, the director of the US National Institutes for Health (NIH) said the agency would not fund such editing of human embryo genes.
“Research using genomic editing technologies can and are being funded by NIH,” Francis Collins said Wednesday. “However, NIH will not fund any use of gene-editing technologies in human embryos. The concept of altering the human germline in embryos for clinical purposes ... has been viewed almost universally as a line that should not be crossed.”
Although the discovery of CRISPR sequences dates back to 1987 – when it was first used to cure bacteria of viruses – its successes in higher animals and humans were only achieved in 2012-13, when scientists achieved a revolution by combining the resulting treatment system with Cas9 for the first time.
On April 17, the MIT’s Broad Institute announced that has been awarded the first-ever patent for working with the Crisp-Cas9 system.
The institute’s director, Eric Lander, sees the combination as “an extraordinary, powerful tool. The ability to edit a genome makes it possible to discover the biological mechanisms underlying human biology.”
The system’s advantage over other methods is in that it can also target several genes at the same time, working its way through tens of thousands of so-called 'guide' RNA sequences that lead them to the weapon to its DNA targets.
Meanwhile, last month in the UK, a healthy baby was born from an embryo screened for genetic diseases, using karyomapping, a breakthrough testing method that allows doctors to identify about 60 debilitating hereditary disorders.

There’s real pressure on the aviation industry to introduce faster, cheaper and greener aircraft, while maintaining the high safety standards demanded of airlines worldwide.
Airlines carry more than three billion passengers each year, which presents an enormous challenge not only for aircraft manufacturers but for the civil aviation infrastructure that makes this extraordinary annual mass-migration possible. Many international airports are close to or already at capacity. The International Air Transport Association (IATA) has estimated that, without intervention, many global airports – including major hubs such as London Heathrow, Amsterdam Schiphol, Beijing and Dubai – will have run out of runway or terminal capacity by 2020.
The obvious approach to tackling this problem is to extend and enlarge airport runways and terminals – such as the long-proposed third runway at London Heathrow. However there may be other less conventional alternatives, such as introducing in-flight refuelling for civil aircraft on key long-haul routes. Our project, Research on a Cruiser-Enabled Air Transport Environment (Recreate), began in 2011 to evaluate whether this was something that could prove a viable, and far cheaper, solution.
If in-flight refuelling seems implausible, it’s worth remembering that it was first trialed in the 1920s, and the military has continued to develop the technology ever since. The appeal is partly to reduce the aircraft’s weight on take-off, allowing it to carry additional payload, and partly to extend its flight range. Notably, during the Falklands War in 1982 RAF Vulcan bombers used in-flight refuelling to stage what was at the time the longest bombing mission ever, flying 8,000 miles non-stop from Ascension Island in the South Atlantic to the Falklands and back.
Reducing take-off weight could offer many benefits for civilian aircraft too. Without the need to carry so much fuel the aircraft can be smaller, which means less noise on take-off and landing and shorter runways. This opens up the network of smaller regional airports as new potential sites for long-haul routes, relieving pressure on the major hubs that are straining at the seams.
There are environmental benefits too, as a smaller, lighter aircraft requires less fuel to reach its destination. Our initial estimates from air traffic simulations demonstrate that it’s possible to reduce fuel burn by up to 11% over today’s technology by simply replacing existing global long-haul flight routes with specifically designed 250-seater aircraft with a range of 6,000nm after one refuelling – roughly the distance from London to Hong Kong. This saving could potentially grow to 23% with further efficiencies, all while carrying the same number of passengers the same distance as is possible with the current aircraft fleet, and despite the additional fuel burn of the tanker aircraft.
Imagine if these Tornado fighter jets were 250-seater passenger aircraft and you’ve got the idea.
However, this is not the whole picture – in-flight refuelling will require the aerial equivalent of petrol stations in order to deliver keep passenger aircraft in the sky. With so much traffic it simply wouldn’t be possible to refuel any aircraft any time, anywhere it was needed. The location of these refuelling zones, coupled with the flight distance between the origin and destination airports can greatly affect the potential benefits achievable, possibly pulling flights away from their shortest route, and even making refuelling on some routes impossible – if for example the deviation to the nearest refuelling zone meant burning as much fuel as would have been saved.
Safety and automation
As with all new concepts – particularly those that involve bringing one aircraft packed with people and another full of fuel into close proximity during flight – it’s quite right to ask whether this is safe. To try and answer this question, the Dutch National Aerospace Laboratory and German Aerospace Centre used their flight simulators to test the automated in-flight refuelling flight control system developed as part of the Recreate project.One simulator replicated the manoeuvre from the point of view of the tanker equipped with an in-flight refuelling boom, the other simulated the aircraft being refuelled mid-flight. Critical test situations such as engine failure, high air turbulence and gusts of wind were simulated with real flight crews to assess the potential danger to the operation. The results were encouraging, demonstrating that the manoeuvre doesn’t place an excessive workload on the pilots, and that the concept is viable from a human as well as a technical perspective.
So far we’ve demonstrated the potential aerial refuelling holds for civilian aviation, but putting it into practice would still pose challenges. Refuelling hubs would need to be established worldwide, shared between airlines. There would need to be fundamental changes to airline pilot training, alongside a wider public acceptance of this departure from traditional flight operations.
However, it does demonstrate that, in addition to all the high-tech work going into designing new aircraft, new materials, new engines and new fuels, the technology we already have offers solutions to the long-term problems of ferrying billions of passengers by air around the world.
