Scanner Reveals Inner Workings Of How Our Brains Are Wired

Curvature in this image of a whole human brain turns out to be folding of 2D sheets of parallel neuronal fibers that cross paths at right angles

How Our Brains Are Wired: Scanner Reveals Inner Workings In Stunning New Detail -- The Brain

For a long time it was thought that the brain was a mass of tangled wires, but researchers recently found that its fibers are actually set up like a chess board, crossing at right-angles.

What’s more, this grid structure has now been revealed in amazing detail as part of a brain imaging study by a new state-of-the-art magnetic resonance imaging (MRI) scanner.

Van Wedeen, of Massachusetts General Hospital (MGH), who led study, said: ‘Far from being just a tangle of wires, the brain's connections turn out to be more like ribbon cables - folding 2D sheets of parallel neuronal fibers that cross paths at right angles, like the warp and weft of a fabric.

China: No Coup Rumors Please .... Or You Go To Jail

Hundreds of millions of Chinese people use social media websites, despite strict censorship. [Reuters]

China Arrests Over Coup Rumours -- BBC

Chinese police have arrested six people and shut 16 websites after rumours were spread that military vehicles were on the streets of Beijing, officials say.

The web posts were picked up last week by media outlets around the world, amid uncertainty caused by the ouster of top political leader Bo Xilai.

The State Internet Information Office (SIIO) said the rumours had a "very bad influence on the public".

Two popular microblogs have temporarily stopped users from posting comments.

Cassini Spacecraft Captures Saturn Moon Geyser Images -- BBC

The Cassini spacecraft has captured striking images from flying by three moons of Saturn, including new pictures of Enceladus's gushing geysers.

Cassini made its lowest pass yet over the south pole of Enceladus, at at an altitude of 74km (46 miles).

This allowed it to "taste" the jets of water vapour and ice that the moon spews forth into space.

The Nasa probe also made relatively close flypasts of two other Saturnian satellites: Dione and Janus.

A History Of Breast Enlargements


A Brief History Of Breast Enlargements -- BBC

It is 50 years since the first breast enlargement using silicone implants. Today it rates as the second-most popular form of cosmetic surgery worldwide, undergone by 1.5 million women in 2010.

It was spring 1962 when Timmie Jean Lindsey, a mother-of-six lay down on the operating table at Jefferson Davis hospital in Houston, Texas.

Over the next two hours, she went from a B to a C cup, in an operation that made history.

"I thought they came out just perfect… They felt soft and just like real breasts," says Lindsey now aged 80.

"I don't think I got the full results of them until I went out in public and men on the street would whistle at me."

Controversial Pesticide Linked To Bee Collapse -- Wired Science

A controversial type of pesticide linked to declining global bee populations appears to scramble bees’ sense of direction, making it hard for them to find home. Starved of foragers and the pollen they carry, colonies produce fewer queens, and eventually collapse.

The phenomenon is described in two new studies published March 29 in Science. While they don’t conclusively explain global bee declines, which almost certainly involve a combination factors, they establish neonicotinoids as a prime suspect.

With Google Earth No One Can Hide The Slums


With Google Earth, India Can No Longer Hide Its Shantytowns And "Slumdogs" -- Time/AP

SANGLI — Before Google Earth existed, the slums of Sangli, a city of 550,000 in southwestern India, was acknowledged on government maps by nothing more than some clumsily outlined, empty spaces. But then, from high in the sky, the eye of a satellite saw what no municipal geometer had taken the trouble to show: small islands of huts with dilapidated roofs spread throughout the city.

Thanks to the satellite images available on Google Earth, a full picture of these forgotten slums has emerged. They now have borders; they are mapped; they have an identity. And using these images, Shelter Associates, a Pune-based NGO, has begun rehabilitating the slums. For the first time in their lives, 3,900 families in Sangli are going to be moving into apartments.

Future Wars Will Be Fought By Hackers

Richard Clarke On Who Was Behind the Stuxnet Attack -- Smithsonian

America's longtime counterterrorism czar warns that the cyberwars have already begun—and that we might be losing.


The story Richard Clarke spins has all the suspense of a postmodern geopolitical thriller. The tale involves a ghostly cyberworm created to attack the nuclear centrifuges of a rogue nation—which then escapes from the target country, replicating itself in thousands of computers throughout the world. It may be lurking in yours right now. Harmlessly inactive...or awaiting further orders.

A great story, right? In fact, the world-changing “weaponized malware” computer worm called Stuxnet is very real. It seems to have been launched in mid-2009, done terrific damage to Iran’s nuclear program in 2010 and then spread to computers all over the world.

Jupiter Helps Halley’s Comet Give Us More Spectacular Meteor Displays -- Science Daily

ScienceDaily (Mar. 27, 2012) — The dramatic appearance of Halley's comet in the night sky has been observed and recorded by astronomers since 240 BC. Now a study shows that the orbital influences of Jupiter on the comet and the debris it leaves in its wake are responsible for periodic outbursts of activity in the Orionid meteor showers. The results will be presented by Aswin Sekhar at the National Astronomy Meeting in Manchester on the 27th of March.

Halley's comet orbits the Sun every 75-76 years on average. As its nucleus approaches the Sun, it heats up and releases gas and dust that form the spectacular tail. This outgassing leaves a trail of debris around the orbit.

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.

My Comment: 5 rockets launched one after another .... that must have been a cool display. When video becomes available, I will post it.

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.

Earth’s Upper Atmosphere Absorbed 26 Billion kWh Of Energy



Earth’s Upper Atmosphere Hit by 26 Billion kWh of Energy -- Sci-Tech Daily

As researchers to continue monitor and assess the recent solar activity, new data shows that the thermosphere absorbed 26 billion kWh of energy over a three day period, March 8th -10th.

A recent flurry of eruptions on the sun did more than spark pretty auroras around the poles. NASA-funded researchers say the solar storms of March 8th through 10th dumped enough energy in Earth’s upper atmosphere to power every residence in New York City for two years.

How George Takei Conquered Facebook -- Forbes

George Takei earned his fame on the original Star Trek for playing Lieutenant Hikaru Sulu on the Enterprise, and later Captain Sulu of the Excelsior in the movies. As a Starfleet officer, Sulu was dedicated to peaceful exploration. But when it comes to Facebook, he’s a conqueror. On March 23, 2011, Takei put up his fan page. Now, one year later, he has nearly 1.4 million fans on his Facebook page, who regularly like, share, and comment on his near endless stream of posts, videos and geeky pictures. By way of comparison, Twitter master Star Trek alum Wil Wheaton has a little over 76,000 fans and Captain Kirk himself, William Shatner, has a little over 137,000.

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.

Is This Finally Proof We're NOT Causing Global Warming?

Evidence that the Earth heated up over a 1,000 years ago was found in a rare mineral called ikaite

Is This Finally Proof We're NOT Causing Global Warming? The Whole Of The Earth Heated Up In Medieval Times Without Human CO2 Emissions, Says New Study -- Daily Mail

* Evidence was found in a rare mineral that records global temperatures
* Warming was global and NOT limited to Europe
* Throws doubt on orthodoxies around 'global warming'

Current theories of the causes and impact of global warming have been thrown into question by a new study which shows that during medieval times the whole of the planet heated up.

It then cooled down naturally and there was even a 'mini ice age'.

A team of scientists led by geochemist Zunli Lu from Syracuse University in New York state, has found that contrary to the ‘consensus’, the ‘Medieval Warm Period’ approximately 500 to 1,000 years ago wasn’t just confined to Europe.

In fact, it extended all the way down to Antarctica – which means that the Earth has already experience global warming without the aid of human CO2 emissions.

Which Tablet Runs The Hottest?


New iPad Versus 5 Tablet Competitors: Which Runs Hottest? -- Gadget Lab

You need not fear heat blisters when handling the new iPad. Apple’s new tablet is neither a burn risk, nor even particularly hot in the grand scheme of competing devices.

We know because we tested the iPad against five other tablets.

Sure, the new iPad, like all electronics hardware, heats up when pushed to its limits. This is just a matter of physics. Processors, batteries and back-lit displays generate heat under load.

Consumer Reports proved this when it recorded a temperature of 116 degrees Fahrenheit on the back of the new iPad — this after plugging the tablet into a wall socket and playing a demanding 3-D game, Infinity Blade 2, for 45 minutes. This little stunt spurred a lot of online chatter, but it didn’t explain whether the new iPad’s heat generation is above and beyond that of other tablets on the market.

So Wired decided to investigate.

Smallest Planet Yields Big Surprises -- Science News

Mercury has a complicated inside and an active geologic past.

For starters, the planet’s interior is built differently than anything else scientists have blueprints for. Unlike Earth’s, Mercury’s core — which gobbles up 85 percent of the planet’s radius — consists of three layers instead of two. At the planet’s heart lies a probable solid layer, surrounded by a swirling liquid iron layer, all encapsulated by a third, solid iron-sulfur layer.

The new MESSENGER results were presented on March 21 at the Lunar and Planetary Science Conference, as well as in two papers appearing online in Science. One paper discusses the gravity measurements leading to the new model of the planet’s interior, and the other describes surface features in the northern hemisphere.

Top 50 Android Phone Apps

Android is interesting, because it attracts two very different kinds of people.

The Top 50 Android Phone Apps -- The Guardian

Android has overtaken iOS as the UK's most popular smartphone platform. We pick the best of its 450,000 apps, for music fans, children, gamers, shoppers… There's even an antidote for app addiction

There is far more to smartphone life than Apple's iPhone. Google launched its Android software in 2008 and has since sold more than 300m of its smartphones; currently, more than 850,000 are added to that number every day.

More than 450,000 apps are available on Google Play, which is generating more than 1bn app downloads every month. The latest Android smartphones are also viable competitors to the iPhone (stylish and powerful phones from companies such as Samsung, HTC and Sony Ericsson have been flying off the shelves in the UK), but Android apps haven't always had a great press. Android has been criticised on security grounds, with accusations that there are more viruses and malware apps on Google's store than on Apple's App Store. However, Android apps have to ask for explicit permission to access your personal data and phone features, so familiarise yourself with these permissions requests when installing apps and you'll be less at risk.
