Nuclear Fusion Is A Real Possibility, New Models Suggest -- Live Science

If new computer simulations pan out in the real world, nuclear fusion, the power source that makes stars shine, may be a practical possibility here on Earth, scientists say.

Simulations at Sandia National Laboratories in New Mexico revealed a fusion reactor that surpasses the "break-even" point of energy input versus energy output, indicating a self-sustaining fusion reaction. (This doesn't break any laws of physics for the same reason that starting a fire with a match doesn't).

International Space Station Nearly Struck By Space Junk

International Space Station Nearly Struck By Space Junk: Six Astronauts Nearly Had To Abandon Ship After A Piece Of A Russian Rocket Nearly Collided With The International Space Station -- Chicago Tribune/US News and World Report

Sometime Friday afternoon, the six people--including two Americans--aboard the International Space Station got a warning: Head into the nearest Russian Soyuz spacecraft and wait for further instructions, because a chunk of a disabled Russian rocket was hurtling towards them at speeds of over 17,000 miles per hour.

The threat of man-made space debris is increasingly becoming a problem for astronauts and the nearly 700 satellites orbiting earth. NASA estimates there are about 19,000 man-made objects orbiting earth--at orbital speeds, even a tiny particle can destroy satellites or cause serious damage to the space station.

Can We Build Robots With Morals?

Artificial Intelligence Pioneer: We Can Build Robots With Morals -- Jewish World Review

Like it or not, we're moving computers closer to autonomy.

Judea Pearl, a pioneer in the field of artificial intelligence, won the Association for Computing Machinery's A.M. Turing award earlier this month, considered the highest honor in the computing world.

Pearl developed two branches of calculus that opened the door for modern artificial intelligence, such as the kind found in voice recognition software and self-driving cars.

My Comment: I am sure that we can build boundaries/morals for robots to function .... but then again .... we can also build robots with morals that are not to our liking.

Military Robot Shaves Human Head

Short-Circuit, Back And Sides: Military Robot Shaves Human Head -- Daily Mail

The drastic change of image that comes with having your head shaved is scary enough – but one man doubled the terror by letting a robot do the job for him.

The prototype robot was a Multi-Arm UGV (Unmanned Ground Vehicle) from U.S company Intelligent Automation Inc (IAI) in Maryland – and is designed to tackle IEDs, check backpacks for bombs and breach doors.

But on this occasion it was armed with multiple clippers to cut the hair of an IAI volunteer, who went through the ordeal to raise money for cancer charity the St. Baldrick's Foundation.

People Are Becoming More Selfish

Newer Generations Increasingly About “Me,” Study Finds -- Courtesy of the American Psychological Association and World Science Staff

oung Amer­i­cans care less and less about the the en­vi­ron­ment, pol­i­tics, and the world around them in gen­er­al, a study has found; even the idea of seek­ing a mean­ing­ful life is out of fash­ion.

In­stead, mon­ey, im­age and fame are the idols of our time.

“Pop­u­lar views of the mil­len­ni­al genera­t­ion, born in the 1980s and 1990s, as more car­ing, com­mun­ity-oriented and pol­i­tic­ally en­gaged than pre­vi­ous genera­t­ions are largely in­cor­rect, par­tic­u­larly when com­pared to ba­by boomers and Genera­t­ion X at the same age,” said the stu­dy’s lead au­thor, Jean Twenge, a psy­chol­o­gist at San Die­go State Uni­vers­ity and au­thor of the book Genera­t­ion Me. “These da­ta show that re­cent genera­t­ions are less likely to em­brace com­mun­ity mind­ed­ness and are fo­cus­ing more on mon­ey, im­age and fame.”

NASA Launches Five-Rocket Science Extravaganza At Last -- MSNBC/Space

ATREX mission studies high-level winds; glowing trails visible in skies over East Coast

At almost literally the last minute, NASA launched five suborbital sounding rockets early Tuesday on a mission to study high-level jet stream winds by creating artificial glowing clouds near the edge of space.

After several delays, the rockets started blasting off from their pads in Virginia just before the close of the day's scheduled launch window at 5 a.m. ET. The launches were held up until the very end by concerns about winds as well as boats that had strayed into the restricted range zone. But all the conditions turned "green" just in time for liftoff.

Can Weight-Loss Surgery Cure Diabetes?

New Study: Weight-Loss Surgery May Cure Diabetes -- CBS

Could weight-loss surgery be a cure for type 2 diabetes? That's exactly what a new study, published today by the New England Journal of Medicine, suggests.

The study showed that weight-loss surgery is dramatically more effective in the treatment of type 2 diabetes than a conventional treatment of diet changes and medication. Patients in the study suffered from severe type 2 diabetes, and most went into remission after undergoing one of two bariatric surgeries.

The Powerful Antioxidant Properties Of Popcorn

Popcorn Has More Antioxidants Than Fruit, Study Says -- FOX News

Long heralded as a low-calorie snack, new research indicates popcorn may actually be good for your health in other ways as well.

Pennsylvania researchers reported popcorn actually contains more healthy antioxidants called polyphenols than fruits and vegetables. The study found that there were 300 mg of polyphenols in a serving of popcorn, compared to 160 mg in a serving of fruit.

Polyphenols have been shown in prior studies to boost cardiovascular health as well as protect against chronic diseases.

My Comment: But soaking it in butter and salt probably counteracts the positive aspects of popcorn.

How Turbines Can Replace A Heart

Man With No Pulse: How Turbines Can Replace A Heart -- New Scientist

You no longer need a heartbeat to be alive. In a groundbreaking surgery last year, doctors William Cohn and Bud Frazier from the Texas Heart Institute in Houston replaced a dying man's heart with twin turbines, resulting in the first living person without a pulse.

In this short film called Heart Stop Beating, directed by Jeremiah Zagar, you can follow the revolutionary procedure. Compared to artificial hearts that mimic real ones, the device is thought to be much more durable, since it has no flexible membranes or complex twisting mechanisms. "No one has been able to make a self-contained pulsatile device that can last more than two years or so and most wear out sooner," says Cohn.

Did Carbon Dioxide Just Save The Earth?

Earth's atmosphere lights up at infrared wavelengths during the solar storms of March 8-10, 2012. A ScienceCast video explains the physics of this phenomenon. Play it!

Carbon Dioxide Just Saved Earth -- Don Surber

God bless the John Amos power plant across the river from Poca, West Virginia, and all the other producers of CO2.

Those tiny molecules of carbon dioxide along with their cousins, nitric oxide, spared life on the planet from becoming crispy critters earlier this month.

It seems the Sun belched its biggest a coronal mass ejection in 7 years and the thermosphere absorbed 26 billion kWh of energy. The thermosphere is part of that invisible cloud of gases that blankets the Earth. Scientists call it the atmosphere.

Assuage Your Liberal Guilt With An Eco-Friendly SuperYacht -- Science 2.0

Let's be honest, if you are a Republican, you don't care about the environment because you received your own oil well when you registered to vote. And you like vampire babies. So you do not care about the emissions of your yacht.

But if you are a rich Democrat, things are a little dicier. Buying pretend carbon offsets for a 29,000 square foot house can only get you so far. If you want to own a superyacht too, that's a lot of liberal guilt to agonize over. What to do?

Woman, 83, Sues Apple Aafter Walking Into their Glass Door

‘Pane’ & Suffering At The Apple Store -- New York Post

Glassed granny walks smack into $1M suit

For one 83-year-old grandma, the most confusing piece of technology at an Apple Store wasn’t an iPad or iPhone — it was the front door.

Evelyn Paswall, a former Manhattan fur-company vice president, claims the tech company’s signature glass architecture is a menace to little old ladies after she failed to see the glass door at a Long Island location and smashed her face.

Now the Forest Hills, Queens, resident is suing Apple for $1 million, saying the company was negligent for not elderly-proofing the store’s see-through facade.

New Hope For Balding Men?

New Discovery Brings Hope For Balding Men -- The Telegraph

Scientists have identified a hair-loss protein in a development that could pave the way for a cure for male-pattern baldness.

The discovery could mean treatments are developed to suppress the protein and to stop baldness, although it would not reverse the effects to reverse hair loss.

Tests were carried out on tissue from the scalps of more than 20 men with male pattern baldness, known as androgenic alopecia (AGA).

The results showed bald areas had levels of the protein PGD2 three times higher than hairy areas.

James Cameron's Successfully Completes Mariana Trench Pacific Dive

James Cameron Describes Mariana Trench After Pacific Dive -- ABC News

In 1997 James Cameron famously sent the RMS Titanic to the ocean floor. Now he has made an even deeper trip himself: in a submersible called the Deepsea Challenger, he descended to the bottom of the Mariana Trench -- seven miles beneath the western Pacific Ocean, deeper than Mt. Everest is high.

And he lived to tell about it. Today, on a conference call to reporters from the research vessel Mermaid Sapphire, he enthused about the mystery and adventure of being all alone in the darkness, 35,576 feet beneath the surface of the sea.

"I just sat there looking out the window, looking at this barren, desolate lunar plain, appreciating," Cameron said.
