#Bacterial nanowires: Not what we thought they were For the past 10 years scientists have been fascinated by a type of electric bacteria that shoots out long tendrils like electric wires using them to power themselves
In many ways it turned out to be an even cleverer way for bacteria to power themselves said El-Naggar corresponding author of the study who was named a Popular Science Brilliant 10 researcher in 2012 for his pioneering work
During the formation of nanowires scientists noted an increase in the expression of electron transport genes but no corresponding increase in the expression of pilin genes.
Understanding the way these electric bacteria work has applications well beyond the lab. Such creatures have the potential to address some of the big questions about the nature of life itself including

We're looking at a revolution in transportation he says. For Bond the engine represents the beginning of the world's first fully reusable spaceship a new kind of craft that promises to do
The vehicle would have a fuselage reminiscent of the Concorde and take off like a conventional airliner accelerate to Mach 5. 2
and blast out of the atmosphere like a rocket. On the return trip Skylon would touch down on the same runway it launched from.
That price would even undercut the $50 million sum that private spaceflight company Spacex plans to charge to launch cargo on its two-stage Falcon 9 rocket.
and his crew plan to turn to public and private investors for the remaining $3. 6 billion necessary to complete the engine
which they say could be ready for flight tests in the next four years. Building the craft itself would require a much heftier investment:
because we felt it was better to focus our efforts on other less costly ways to get payloads to orbit says Dan Dumbacher NASA's deputy associate administrator for exploration systems development who spent two years working on the X-33.
They can haul more cargo and more fuel than single-stage craft. Rockets also offer reliability on average only one out of 20 launches fail in part

supersonic aviation. It could enable an aircraft to fly anywhere in the world in under four hours says Bond.
When air strikes an engine at five times the speed of sound it can heat up to nearly 2000 degrees Fahrenheit.
If and when the engine passes flight tests one of Reaction engines'plans is to license the technology to a potential partner in the aerospace industry.
Truthfully Skylon or SSTO is the only way to make space common. Imagine a fleet of these vehicles whisking payloads to LEO on a daily basis
It all starts with regular SSTO flights. Very awesome breakthrough on heat exchange. This single breakthrough will ripple through a host of applications.
This saves on the weight of oxygen that would otherwise be needed for the flight through the atmosphere.
Most aircraft are designed to fly with a nose up angle of attack. This way the fuselage generates lift.
Since the engine inlet is extremely sensitive to the direction of airflow at high mach numbers it is angled down 7 degrees
but then they wouldn't have a convenient place for the rear landing gear and having the engines close to the ground makes them easier to service.
4. If LOX is an oxidiser for at least part of the flight where is the tank?
5. If LOX is used for part of the flight its weight needs to be factored in. Not just the weight of liquid hydrogen.

#FAA Panel Recommends Lifting Ban On Gadget Use During Flights After receiving countless complaints abuse towards flight attendants who are only doing their jobs
whether electronic gadgets actually are dangerous during a flight's takeoff and landing. A 28-person advisory panel just concluded its study
while taking off if the panel has its way. Not that you probably could; the airplane's speed means that you'll be switching from tower to tower faster than your phone

So you can't stream#your favorite TV SHOW but if you've downloaded it and flipped your gadget to airplane mode watch away.
Gadget manufacturers have been campaigning for years for a change in the FAA's policy (which currently bans any electronic use
when the plane is below 10000 feet). Amazon especially is annoyed as its Kindle ebook reader suffers a distinct weakness compared with physical books given that you aren't currently allowed to use a Kindle during part of your flight.
