New Hope For An Alzheimer Treatment

Injection Offers Alzheimer's Hope -- The Telegraph

Hopes have been raised for new Alzheimer's treatments after scientists found an injection could stop the body from killing brain cells by "cutting off" their protein supply.

Researchers found that by injecting a protein into the brain, they could protect nerve cells in the brains of mice with prion disease, a condition which normally causes the brain to slowly die.

Because the process by which prion disease affects the brains of mice is similar to some degenerative brain conditions in humans, it is hoped that the findings could lead to breakthroughs in the treatment of Alzheimer's or Parkinson's.

Vesta A Baby Planet, Not An Asteroid -- ABC News (Australia)

Vesta, the second largest object in the main asteroid belt, has an iron core, a varied surface, layers of rock and possibly a magnetic field - all signs of a planet in the making, not an asteroid.

So concludes an international team of scientists treated to a virtual front row seat at Vesta for the past 10 months, courtesy of NASA's Dawn robotic probe.

They have a bit more ground to cover before Dawn leaves Vesta's cratered, lava-like surface in late August to rendezvous with the king of the asteroid belt, Ceres, another type of proto-planet believed to be flush with water ice.

Microsoft's Bing Search Engines To Use Social media Platforms

The new social results will appear in a grey column on the right-hand side of Bing's results page

Microsoft's Bing Search Engines To Use Facebook Tips -- BBC

Microsoft is revamping its Bing search engine to include advice from Facebook and other social media platforms.

The move involves the introduction of a new sidebar which seeks to connect users with friends and other enthusiasts who can provide help.

The firm says it is based on the fact "90% of people consult with a friend or expert before making a decision".

Surveys suggest Bing has about a 15% share of the US search market, lagging behind Google's 66% portion.

My Comment: It's about time that search engines start using social media outlets like Facebook for results.

Facebook Starts Charging

If Apple and Google can do it, so can social network Facebook - the site is to launch an 'app store' to showcase the games and apps that earn the site much of its revenue

Facebook Starts Charging: Site Launches Its Own App Store To Take On Apple And Google - And You'll Have To PAY For Some Up Front -- Daily Mail

* App store offers first time for developers to charge consumers directly
* 'In-app' purchases already a major source of social site's revenue
* Will also offer apps for Android and iPhone

If Apple and Google can do it, so can social network Facebook - the site is to launch an 'app store' to showcase the games and apps that earn the site much of its revenue.

The app store will also allow developers to sell apps direct to consumers for the first time via the network.

It's the latest in a series of moves to 'spruce up' the number one social network in advance of a flotation on the stock market expected to take place later this month - and to convince investors it CAN earn more money.

FBI Pushes For Surveillance Backdoors On Internet Companies

FBI: We Need Wiretap-Ready Web Sites - Now -- CNET

CNET learns the FBI is quietly pushing its plan to force surveillance backdoors on social networks, VoIP, and Web e-mail providers, and that the bureau is asking Internet companies not to oppose a law making those backdoors mandatory.

The FBI is asking Internet companies not to oppose a controversial proposal that would require firms, including Microsoft, Facebook, Yahoo, and Google, to build in backdoors for government surveillance.

In meetings with industry representatives, the White House, and U.S. senators, senior FBI officials argue the dramatic shift in communication from the telephone system to the Internet has made it far more difficult for agents to wiretap Americans suspected of illegal activities, CNET has learned.

How Much Water Is On Planet Earth?

If You Collected All Of Earth’s Water Into A Sphere, How Big Would It Be? -- io9

Imagine the Earth in your mind's eye. Now round up all the water on the planet into a sphere (we're talking oceans, icecaps, atmosphere, everything — even the water bound up in you and me). How big do you think that sphere would be compared to the Earth?

Got your answer? Our water sphere would have a diameter of 1,385 kilometers (about 860 miles), and span the distance from Salt Lake City, Utah to Topeka, Kansas. A sphere this far across would have a volume equal to about 1,386 million cubic kilometers (roughly 332,500,000 cubic miles). Those might sound like big numbers (and they certainly are big numbers) but wait until you see this sphere beside the Earth.

Testing the Long-Awaited Fisker Karma Plug-In Hybrid -- Popular Science

At the 2008 Detroit Auto Show, the start-up Fisker Automotive unveiled its Karma concept , a high-end plug-in hybrid the company would use to challenge Tesla Motors. Cofounder Henrik Fisker said the Karma would go on sale in late 2009. Then the recession, a switch in battery suppliers and other delays kept Fisker from shipping the first trickle of cars until late last year. This spring, we got one of the first test drives.

U.S. Army Wants To Give War Robots More Power To 'Make Their Own Decisions'

Giving war robots 'autonomy' sparks fears of independent killing machines similar to Arnold Schwarzenegger's The Terminator

What Could Possibly Go Wrong? U.S. Army Wants To Give War Robots More Power To 'Make Their Own Decisions' -- Daily Mail

* Trucks that 'drive themselves' already under test
* Military is testing 'autonomous' robots that follow soldiers
* Robots will use laser-imaging to build their own 3D image of the world
* Will be 'supervised' by soldiers

Armies of robots including dog-like creatures walking on four legs and huge lumbering trucks are the stuff of science fiction - specifically, bleak films such as The Terminator series.

But the U.S. military not only wants more robots - it wants more 'autonomous' robots, robots free to make their own decisions on the battlefield.

A new robot is described as 'like a dog' that follows troops on the battlefield - and future models will use technologies such as laser imaging to build their own picture of the world.

Omnivorous Black Holes Like This One Are Pretty Much the Sharks of Space - -Popular Science

Scientists from the Harvard-Smithsonian Center for Astrophysics and Johns Hopkins University report seeing a phenomenon we've all imagined: a black hole devouring a star.

A black hole at the center of a galaxy about 2.7 billion light-years away, one about the same size as the black hole at the center of our own Milky Way, was observed sucking the life out of a star. Interestingly, the scientists who observed the black hole's meal compared it to a shark: neither, says Ryan Chornock of Harvard-Smithsonian, are unstoppable eating machines.

Two Hundred Years of Surgery

Two Hundred Years of Surgery -- New England Journal Of Medicine

Surgery is a profession defined by its authority to cure by means of bodily invasion. The brutality and risks of opening a living person's body have long been apparent, the benefits only slowly and haltingly worked out. Nonetheless, over the past two centuries, surgery has become radically more effective, and its violence substantially reduced — changes that have proved central to the development of mankind's abilities to heal the sick.

Spychips For Soldiers

U.S. Military Developing Spychips For Soldiers -- WND

Government wants 'health' benefits from nanosensors.

The U.S. military wants to plant nanosensors in soldiers to monitor health on future battlefields and immediately respond to needs, but a privacy expert warns the step is just one more down the road to computer chips for all.

“It’s never going to happen that the government at gunpoint says, ‘You’re going to have a tracking chip,’” said Katherine Albrecht, who with Liz McIntyre authored “Spychips,” a book that warns of the threat to privacy posed by Radio Frequency Identification.

Is Space Weather A National Security Threat?

A massive explosion on the sun's surface has triggered the largest solar radiation storm since 2005, hurling charged particles at Earth. (NASA / May 4, 2012)

Space Weather Expert Has Ominous Forecast -- L.A. Times

Mike Hapgood, who studies solar events, says the world isn't prepared for a truly damaging storm. And one could happen soon.

A stream of highly charged particles from the sun is headed straight toward Earth, threatening to plunge cities around the world into darkness and bring the global economy screeching to a halt.

This isn't the premise of the latest doomsday thriller. Massive solar storms have happened before — and another one is likely to occur soon, according to Mike Hapgood, a space weather scientist at the Rutherford Appleton Laboratory near Oxford, England.

My Comment: A giant space storm that knocks-off the world's electrical and communications grid system will be a disaster .... but not a catastrophic one. We will survive .... but trust me .... it is not going to be easy. I should know .... I lived through the Ice Storm of 1998 in Montreal .... an ice storm that knocked-off the electrical grid for a week in my part of Montreal, and longer in the south of Montreal (some regions had no power for a month) .... and before I forget .... this all happened in the middle winter when temperatures outside can easily reach (and did) -20C. We (of course) all survived .... but it was a difficult time, and what bothered me most was the lack of news and information.

Physicists Crack Fusion Mystery -- Technology Review

A new theory might help researchers double the power of fusion reactors.

One reason it's taking decades to develop fusion reactors that can generate electricity is that physicists don't completely understand what's going on in the high-temperature plasma inside a reactor. Under certain conditions, the plasma—which is where fusion reactions take place—disappears in under a millisecond.
