Human Organs: The The Next Frontier In 3-D Printing

The Next Frontier In 3-D Printing: Human Organs -- CNN

(CNN) -- The emerging process of 3-D printing, which uses computer-created digital models to create real-world objects, has produced everything from toys to jewelry to food.

Soon, however, 3-D printers may be spitting out something far more complex, and controversial: human organs.

For years now, medical researchers have been reproducing human cells in laboratories by hand to create blood vessels, urine tubes, skin tissue and other living body parts. But engineering full organs, with their complicated cell structures, is much more difficult.

Enter 3-D printers, which because of their precise process can reproduce the vascular systems required to make organs viable. Scientists are already using the machines to print tiny strips of organ tissue. And while printing whole human organs for surgical transplants is still years away, the technology is rapidly developing.

How To Levitate And Melt An Aluminum At The Same Time

An Aluminum Slug Melts And Levitates At The Same Time -- io9

Run an alternating current through a coiled length of copper and you'll create a levitation cylinder. Drop a bar of aluminum in and you've got yourself some hovering metal. But leave the metal there too long...

The thing about this levitation cylinder is that it doubles as an induction heater. In a nutshell: the current coursing through the copper (which has been coiled to form a solenoid) creates an alternating magnetic field. The magnetic field induces a special form of electrical current (known as eddy currents) in the hovering piece of aluminum. These eddy currents give rise a phenomenon, called Joule heating, that, with enough power, can cause the metal to become very, very hot, as it does here.

What Is The Mystery Light On Mars?

Life on Mars? In this photo taken by the Curiosity rover a light of unknown origin can be seen in the distance

What Is The Mystery Light On Mars? Distant 'Glow' Seen In Curiosity Rover's Latest Photo -- Daily Mail

* A new Nasa photo appears to show an artificial light on the Red Planet
* The image was taken by the Curiosity rover
* One UFO blogger claims it ‘could indicate there is intelligent life below’
* But it is more than likely just an anomaly in the photo
* Many false detections of life on Mars have been claimed before
* Meanwhile, Curiosity is set to study a fascinating Martian region

A strange white speck of 'light' on a recent photograph taken by Curiosity rover has led some to believe that life is thriving on Mars.

UFO blogger Scott Waring claims that the new photograph taken by the rover suggests there are intelligent creatures living underground.

But Nasa, perhaps rather unsurprisingly, are not quite heralding it as the discovery of the century just yet.

The Pentagon's X-37B Has Now Been In Orbit For 500 Days

Will The Pentagon’s Secret Space Plane Ever Return To Earth? -- Kyle Mizokami, Daily Beast

Nearly 500 days into its mission, the Pentagon still won’t say what its drone space shuttle is doing in orbit, or when it might come back.

The Air Force’s secret space plane has been up in orbit for nearly 500 days—a space endurance record. But nearly a year and a half into the mission, the Pentagon still won’t say what the X-37B is doing up there, or when it might come back.

The U.S. Air Force boosted the robotic X-37B atop the nose of an Atlas-5 rocket in December 2012. Since then it’s orbited the Earth thousands of times, overflying such interesting places as North Korea and Iran.

Similar to the Space Shuttle in appearance, the diminutive X-37B is about a quarter the size of the old shuttles. But there are major differences. Lacking a crew, the spacecraft has no cockpit windows. The X-37B has a payload bay about the size of a pickup truck bed.

Is This The 'End Of Days'?

APOCALYPSE NOW: Why A Rare Astrological Event TONIGHT Could Herald The 'End Of Days' -- Express

IF YOU'RE feeling out of sorts today don't worry, it isn't just you.

Mars, Earth, and the Sun will all align tonight, a rare 'opposition of the planets' that only happens once every 778 days.

But what makes this so remarkable is that it comes precisely a week before everyone on earth will see the first of FOUR dark red 'blood moons', an extraordinary event some Christians believe represents the End of Days and the second coming of Christ.

The King James Bible predicts: "The sun shall be turned into darkness, and the moon into blood, before the great and the terrible day of the LORD comes," [Joel 2:31].

And, according to NASA, a highly unusual 'Tetrad' - four successive total 'blood-red' lunar eclipses each followed by six full moons - will, indeed, start a week today and finish on September 28 next year.

U.S. Navy To Test It's Newest Laser Weapon In The Persian Gulf This Summer

U.S. Navy To Test Laser Weapon Aboard Ship In Persian Gulf -- L.A. Times

The Navy plans to install a laser weapon prototype on a ship this summer for at-sea testing in the Persian Gulf.

The technology, called the Laser Weapon System, will be the first of its kind to be deployed, the Navy said.

The idea is that the laser could zap dangerous swarming small boats and flying drones while on the USS Ponce in the Persian Gulf. Its power also can be scaled down, presenting the Navy a non-lethal alternative to ward off threats such as pirates, terrorists and smugglers.

U.S. Navy To Test It's Electromagnetic Gun Aboard A High-Speed Vessel In 2016

U.S. Navy to Test Futuristic, Super-Fast Gun at Sea in 2016 -- Newsweek/Reuters

(Reuters) - The U.S. Navy is planning sea trials for a weapon that can fire a low-cost, 23-pound (10-kg) projectile at seven times the speed of sound using electromagnetic energy, a "Star Wars" technology that will make enemies think twice, the Navy's research chief said.

Rear Admiral Matthew Klunder, the chief of Naval Research, told a round table group recently the futuristic electromagnetic rail gun had already undergone extensive testing on land and would be mounted on the USNS Millinocket, a high-speed vessel, for sea trials beginning in 2016.

"It's now reality and it's not science fiction. It's actually real. You can look at it. It's firing," said Klunder, who planned to discuss progress on the system later on Monday with military and industry leaders at a major maritime event - the Sea-Air-Space Exposition - near Washington.

U.S. Navy Testing Drone Helicopters

U.S. Navy Testing More Sophisticated Pilotless Helicopters -- Reuters

(Reuters) - The helicopter kicked up a cloud of freshly fallen snow that partly obscured the ground below, but despite the poor visibility, it gently touched down in a landing that was unremarkable except for the fact no one was at the controls.

The helicopter, filmed during testing by the Naval Research Laboratory, was piloted by a 100-pound (45-kg) sensor and software package that officials said can turn any rotary-winged aircraft into a virtually autonomous drone able to fly with minimal input from the Marine Corps troops it was designed to serve.

Rear Admiral Matthew Klunder, chief of Naval Research, said the sensor and software pack is "truly leap-ahead technology" that will let a Marine with no flight experience issue landing instructions to a cargo helicopter via tablet computer after just a few minutes of training.

Has The U.S. Navy Found A Way To Make Fuel Out Of Sea Water?

Could You Soon Be Filling Up With SEAWATER? US Navy Reveals 'Game Changing' Fuel Created From Water -- Daily Mail

* Has flown radio controlled plane using 'sea fuel' in first test of new fuel
* New technique can capture 92% of CO2 in water to create jet fuel
* Could be used to create fuel for any vehicle without having to modify engines

The US Navy has developed a radical new fuel made from seawater.

They say it could change the way we produce fuel - and allow warships to stay at sea for years at a time.

Navy scientists have spent several years developing the process to take seawater and use it as fuel, and have now used the 'game changing' fuel to power a radio controlled plane in the first test.

The Future Of Surgical Robotics Is Microscopic

The Microscopic Future of Surgical Robotics -- Erik Sofge, Popular Science

Chances are, you aren’t, and never will be, an astronaut. So the recent revelation that NASA is funding the development of a somewhat gruesome-sounding surgical bot—a fist-size contraption that would enter a patient’s gas-engorged abdomen to staunch bleeding or remove a ruptured appendix—isn’t exactly news you can use. The more relevant announcement might be from Intuitive Surgical, which announced that its newest robo-surgeon has been approved by the FDA. With thinner and more maneuverable arms, the da Vinci Xi will turn more open surgeries into minimally-invasive, robot-assisted procedures. Instead of requiring large incisions to get at various portions of a patient’s anatomy, the Xi will let surgeons reach essentially anywhere in the abdomen through smaller less traumatic punctures. With this clearance, the likelihood that you’ll one day be under the robotic knife just jumped significantly.

How Global Warming Will Affect Your Beer -- Popular Science

A pilot study examines how drought affects the quality of starch in barley.

There are many things that will change as Earth's climate warms. Doctoral student Peter Gous is worried about the price and quality of beer.

The aspiring plant bioengineer worked with a team of scientists to test how not getting enough water altered the quality of barley grains. In a small pilot study, the scientists found that the starches inside barley grains grown with too little water are different from starches found inside nicely-watered barley grains. The dryness-stressed barley had longer-chain starch grains and more protein than normally grown barley. From there, Gous made an interesting conjecture about the future—one we've never thought of.

The Future Of Public Transport?

A web developer from West Yorkshire created his vision for a global Underground network when visiting Australia and wanting to 'nip home' but one engineer said that tunnelling such distances is presently impossible. The style of the ‘Eurocentric’ world Tube map is inspired by the work of Harry Beck, who was the technical draftsman who created the present London Underground map in 1931. The 'Tri-Continental' line on the map is red, like London's Central Line, while the grey line is the 'U.S.' and the black line the'Australasia Pan-Pacific'.

The Future Of Public Transport? Map Reveals How The Entire WORLD Could Be Connected Using A Global Underground Network -- Daily Mail

* Chris Gray from West Yorkshire created his vision for a global Underground network when visiting Australia and wanting to 'nip home'
* His dream is thought to be currently 'impossible' because tunnels would have to be so deep beneath the waves and cross tectonic plates
* One expert thinks pneumatic tube systems like the proposed 'hyperloop' and floating tunnels could connect the world in the future
* The maps are inspired by Harry Beck's map of the London Underground

Some train journeys feel like they take forever - especially when there are numerous transfers and waits in between flights and trains. But what if you could board a train in Madras, India and travel to Boston with no changes?

One man has imagined the world as a giant London Underground map where people can travel freely between countries and traverse vast bodies of water from the comfort of their seat while vehicles speed through vast tunnels.

While his dream is currently ‘impossible’, engineers are constantly trying to develop new ways to connect countries.

Will Robots Rule the World? Find Out At Robo Madness Next Thursday -- Wade Roush, XConomy

An influential 1998 paper by Robin Hanson, an economics professor at George Mason University, asked what might happen to jobs and wages in a future with “mature machine intelligence”—computers and robots clever enough to take over most human jobs. The outlook is a little scary.

Hanson calculated that a world where machines could truly substitute for most human labor, would, at first, see unprecedented economic growth, including rising wages. But eventually, as machines became more numerous and more productive, they would push human wages down dramatically, leaving most people without the means to buy the stuff the machines were making. Hanson even threw around words like “Malthusian,” a term once reserved to describe catastrophic population growth and food shortages.

Vehicles Will Soon Be Able To Talk To Each Other

Vehicles May Soon Be Talking To Each Other -- Voice of America

WASHINGTON — U.S. regulators are close to approving new standards for enabling vehicles to communicate with each other, hoping the new technology will reduce traffic accidents. Within as little as three years, automakers may be required to equip all new cars with the so-called ‘vehicle-to-vehicle’ communication devices.

Vehicle-to-vehicle, or V2V, is a short-range communication technology that enables vehicles to exchange vital information 10 times per second, about location, speed, acceleration and braking. Cars will be able to calculate the hazard risk within about 300 meters and alert their drivers or even take automatic collision-avoidance action.

The drivers will be able to see, hear and even feel the hazard signals through vibration of the seat.

Blood Moon Eclipse On April 15

Blood Moon Eclipse On April 15 Is A Special Event -- USA Today

Sky watchers are getting ready for an evening of special viewing when a total lunar eclipse arrives just after midnight on April 15.

What's more, this begins a rare sequence of four total lunar eclipses expected over the next two years.

Some Christians see this series of so-called blood moons as linked to a biblical prophecy of the End Times.

A lunar eclipse occurs when the sun, Earth and moon line up so the Earth's shadow falls on the moon, darkening it.

The one on April 15 will begin at 1:20 a.m. on the East Coast, according to Sky and Telescope magazine.
