Did scientists find a lost continent beneath the Indian Ocean?

Analyzing beach sand from Mauritius,?scientists discovered minerals between 660 million and 1,970 million years old, suggesting an ancient, lost?continent beneath the Indian Ocean.

By Charles Q. Choi,?LiveScience / February 25, 2013

The remains of a micro-continent scientist call Mauritia might be preserved under huge amounts of ancient lava beneath the Indian Ocean, a new analysis of island sands in the area suggests.

These findings hint that such?micro-continents?may have occurred more frequently than previously thought, the scientists who conducted the study, detailed online Feb. 24 in the journal Nature Geoscience, say.

Researchers analyzed sands from the isle of Mauritius in the western Indian Ocean. Mauritius is part of a volcanic chain that, strangely, exists far from the edges of its tectonic plate. In contrast, most volcanoes are found at the borders of the tectonic plates that make up the surface of the Earth.

Investigators suggest that volcanic chains in the middle of tectonic plates, such as the Hawaiian Islands, are caused by giant pillars of hot molten rock known as mantle plumes. These rise up from near the Earth's core, penetrating overlying material like a blowtorch. [What Is Earth Made Of?]

Mantle plumes can apparently trigger?continental breakups, softening the tectonic plates from below until they fragment ? this is how the lost continent of Eastern Gondwana ended about 170 million years ago, prior research suggests. A plume currently sits near Mauritius and other islands, and the researchers wanted to see if they could find ancient fragments of continents from just such a breakup there.

Digging in the sand

The beach sands of Mauritius are the eroded remnants of volcanic rocks created by eruptions 9 million years ago. Collecting them"was actually quite pleasant," said researcher Ebbe Hartz, a geologistat the University of Oslo in Norway. He described walking out from a tropical beach, "maybe with a Coke and an icebox, and you dig down underwater into sand dunes at low tide."

Within these sands, investigators discovered about 20?ancient zircon grains?(a type of mineral) between 660 million and 1,970 million years old. To learn more about the source of this ancient zircon, the scientists investigated satellite?maps of Earth's gravity field. The strength of the field depends on Earth's mass, and since the planet's mass is not spread evenly, its gravity field is stronger in some places on the planet's surface and weaker in others.

The researchers discovered Mauritius is part of a contiguous block of abnormally thick crust that extends in an arc northward to the Seychelles islands. The finding suggests Mauritius and the adjacent region overlie an ancient micro-continent they call Mauritia. The ancient zircons they unearthed are shards of lost Mauritia.

The researchers meticulously sought to rule out any chance these ancient grains were contaminants from elsewhere.

"Zircons are heavy minerals, and the uranium and lead elements used to date the ages of these zircons are extraordinarily heavy, so these grains do not easily fly around ? they did not blow into Mauritius from a sandstorm in Africa," Hartz told OurAmazingPlanet.

"We also chose a beach where there was no construction whatsoever ? that these grains did not come from cement somewhere else," Hartz added. "We were also careful that all the equipment we used to collect the minerals was new, that this was the first time it was used, that there was no previous rock sticking to it from elsewhere."

Peeling continent pieces

After analyzing marine fracture zones and ocean magnetic anomalies, the investigators suggest Mauritia separated from Madagascar, fragmented and dispersed as the Indian Ocean basin grew between 61 million and 83.5 million years ago. Since then, volcanic activity has buried Mauritia under lava, and may have done the same to other continental fragments.

"There are all these little slivers of continent that may peel off continents when the?hotspot of a mantle plume?passes under them," Hartz said. "Why that happens is still mind-boggling. Why, after something gets ripped apart, would it rip apart again?"

Finding past evidence of lost continents normally involves tediously crushing and sorting volcanic rocks, Hartz explained. The researchers essentially let nature do the work of pulverization for them by looking at sand.

"We suggest lots of scientists try this technique on their favorite volcanoes," Hartz said.

British Gas owner Centrica's annual earnings rise five percent

LONDON (Reuters) - British utility Centrica unveiled plans to invest more in its residential services business and North America after reporting a 5 percent rise in full-year earnings, in line with expectations.

Centrica, which owns Britain's biggest household energy supplier British Gas, said earnings per share (EPS) for the year to end December rose to 27.1 pence, compared with earnings of 27.4 pence per share according to a Thomson Reuters I/B/E/S poll of 21 analysts.

Centrica, which pulled out of plans to build new nuclear power stations in Britain with partner EDF last month, also announced the resignation of the head of British Gas, Phil Bentley, in a move which had previously been flagged.

Crick's letter about DNA discovery to be sold at auction

NEW YORK | Tue Feb 26, 2013 5:45pm EST

NEW YORK (Reuters) - A letter by Francis Crick, the co-discoverer of DNA, outlining the Nobel Prize-winning achievement to his young son is expected to fetch as much as $2 million when it is sold at auction in April, Christie's said on Tuesday.

Crick and James Watson unraveled the double-helix structure and function of deoxyribonucleic acid (DNA) while working together in Cambridge, England, in 1953. They received the Nobel Prize in medicine in 1962 for their ground-breaking work.

In the seven-page, handwritten letter, Crick, who was 33 years old at the time, described the discovery to his 12-year-old son Michael, who was away at a British boarding school.

"When you come home we will show you the model," he wrote in the letter.

Crick went on to say he believed DNA is a code and that the order of the bases (the letters) makes one gene different from another gene.

"In other words we think we have found the basic copying mechanism by which life comes from life. You can understand that we are very excited," Crick added, before signing the letter, "Lots of love, Daddy."

In his later years Crick was a professor at the Salk Institute for Biological Studies in La Jolla, California. He died in 2004.

The letter, which is being sold by Crick's son, will be part of the books and manuscripts sale on April 10.

A letter dated August 2, 1939, by physicist Albert Einstein to President Franklin Delano Roosevelet warning him of the potential danger of "the construction of extremely powerful bombs" through nuclear fission sold for more than $2 million at auction in 2002.

Blueprint for an artificial brain: Scientists experiment with memristors that imitate natural nerves

Feb. 26, 2013 ? Scientists have long been dreaming about building a computer that would work like a brain. This is because a brain is far more energy-saving than a computer, it can learn by itself, and it doesn't need any programming. Privatdozent [senior lecturer] Dr. Andy Thomas from Bielefeld University's Faculty of Physics is experimenting with memristors -- electronic microcomponents that imitate natural nerves. Thomas and his colleagues have demonstrated that they could do this a year ago. They constructed a memristor that is capable of learning. Andy Thomas is now using his memristors as key components in a blueprint for an artificial brain.

He will be presenting his results at the beginning of March in the print edition of the Journal of Physics published by the Institute of Physics in London.

Memristors are made of fine nanolayers and can be used to connect electric circuits. For several years now, the memristor has been considered to be the electronic equivalent of the synapse. Synapses are, so to speak, the bridges across which nerve cells (neurons) contact each other. Their connections increase in strength the more often they are used. Usually, one nerve cell is connected to other nerve cells across thousands of synapses.

Like synapses, memristors learn from earlier impulses. In their case, these are electrical impulses that (as yet) do not come from nerve cells but from the electric circuits to which they are connected. The amount of current a memristor allows to pass depends on how strong the current was that flowed through it in the past and how long it was exposed to it.

Andy Thomas explains that because of their similarity to synapses, memristors are particularly suitable for building an artificial brain -- a new generation of computers. 'They allow us to construct extremely energy-efficient and robust processors that are able to learn by themselves.' Based on his own experiments and research findings from biology and physics, his article is the first to summarize which principles taken from nature need to be transferred to technological systems if such a neuromorphic (nerve like) computer is to function. Such principles are that memristors, just like synapses, have to 'note' earlier impulses, and that neurons react to an impulse only when it passes a certain threshold.

Thanks to these properties, synapses can be used to reconstruct the brain process responsible for learning, says Andy Thomas. He takes the classic psychological experiment with Pavlov's dog as an example. The experiment shows how you can link the natural reaction to a stimulus that elicits a reflex response with what is initially a neutral stimulus -- this is how learning takes place. If the dog sees food, it reacts by salivating. If the dog hears a bell ring every time it sees food, this neutral stimulus will become linked to the stimulus eliciting a reflex response. As a result, the dog will also salivate when it hears only the bell ringing and no food is in sight. The reason for this is that the nerve cells in the brain that transport the stimulus eliciting a reflex response have strong synaptic links with the nerve cells that trigger the reaction.

If the neutral bell-ringing stimulus is introduced at the same time as the food stimulus, the dog will learn. The control mechanism in the brain now assumes that the nerve cells transporting the neutral stimulus (bell ringing) are also responsible for the reaction -- the link between the actually 'neutral' nerve cell and the 'salivation' nerve cell also becomes stronger. This link can be trained by repeatedly bringing together the stimulus eliciting a reflex response and the neutral stimulus. 'You can also construct such a circuit with memristors -- this is a first step towards a neuromorphic processor,' says Andy Thomas.

'This is all possible because a memristor can store information more precisely than the bits on which previous computer processors have been based,' says Thomas. Both a memristor and a bit work with electrical impulses. However, a bit does not allow any fine adjustment -- it can only work with 'on' and 'off'. In contrast, a memristor can raise or lower its resistance continuously. 'This is how memristors deliver a basis for the gradual learning and forgetting of an artificial brain,' explains Thomas.

Catfight? Workplace conflicts between women get bad rap

Catfight? Workplace conflicts between women get bad rap [ Back to EurekAlert! ] Public release date: 25-Feb-2013

A new study from the University of British Columbia's Sauder School of Business suggests troubling perceptions exist when it comes to women involved in disputes at work.

"Our research shows that when it comes to workplace conflict, women get a bad rap," says PhD candidate Leah Sheppard, who conducted the study with Prof. Karl Aquino. "We show how the negative stereotyping around so-called 'catfights' carry over into work situations."

The researchers asked experiment participants to assess one of three workplace conflict scenarios, all identical except for the names of the individuals involved: Adam and Steven, Adam and Sarah, or Sarah and Anna.

The study, published in the current edition of the journal Academy of Management Perspectives, found that when the scenario depicted female-female conflict, participants perceived there to be more negative implications than the male-male or male-female conflicts.

Participants judged the likelihood of two managers repairing a frayed relationship roughly 15 per cent lower when both managers were female, versus male-male and male-female. Participants rated those involved in all-female conflicts as also being more likely to let the argument negatively influence job satisfaction than male-female or male-male quarrellers.

The study also found that female experiment participants were just as likely as males to see the all-female conflict as more negative.

"This study suggests there's still a long way to go when it comes to the perception of women in the workplace," Sheppard says. "Hopefully, our findings will help to increase managers' awareness of this bias, so they don't let stereotypes guide their decisions on how they staff teams and leverage the full talent of female employees."

###

Backgrounder

For the experiment, Sheppard and Aquino randomly generated a sample of 152 individuals 47 per cent female who were assigned to read about a workplace conflict involving two account managers in a consulting firm.

Participants were asked to make judgments on a scale of one to seven on the likelihood that the two managers would be able to repair their relationship going forward, and the extent to which the conflict would affect their job satisfaction and commitment to the company.

For the first question about whether the two managers would repair the relationship, participants judged the likelihood to be roughly 15 per cent lower when both managers were female, versus male-male and male-female.

For question two, related to job satisfaction, participants rated those involved in the all-female conflict as being 25 per cent more likely than those in the male-female conflict to let the argument negatively influence the way they felt about work, and 10 per cent more likely than the male-male quarrelers.

With mobile apps, the more things change

Change. It seems like the last year has brought more change to mobile apps and the digital publishing space than the previous ten years combined. At the company where I work,?Zinio, we have watched our entire world change as we grew to 5,500 magazines and moved from desktop into PCs, iPads, smartphones and eBooks.

If you?re reading this, it?s a safe bet to say that your reading habits have changed significantly over the past year. Pew Research claims digital media is now the second most popular way to get news. More people reported getting news from online and mobile sites than from radio or print newspapers. This year, for the first time, 100% of publishers will format content for mobile, according to an?Alliance for Audited Media survey of 210 media companies in North America. The development points to the importance of digital publishing as well as the overwhelming change that readers have demanded.

Digital content is truly available anytime and anywhere and app users know it. Publishers get it at varying degrees. Hearst (Elle,?House Beautiful,?O) now reports that smaller tablet sizes have finally moved to digital subscriptions on their biggest titles. In fact 40 percent of its traffic is mobile. But maybe the most high-profile change has come from the oldest magazine in America:?The Atlantic.

The Atlantic has long-embraced mobile apps. In fact it has adapted its content packages extremely well for online, print, and then mobile. It?s 155 years old. But its latest redesign announced on Feb. 21, shows a great willingness to change.

In a Feb. 21 editorial, Editor James Bennett says, ?The Atlantic has also thrived, in part, by changing. To promote the competition of ideas,?The Atlantic now has three Web sites and conducts dozens of live events a year. Our ?printed? words are also conveyed digitally, on the Web and on tablets and phones. We are reaching a far larger audience than we ever have. Optimism about change?impatience for it?was part of the radical founding ethos of?The Atlantic, and this has turned out to be a good thing, today as in 1957, given all the forms and means of expression that are clamoring for your attention (though still not drowning out the poor LP, let alone radio, television, or the picture book?maybe because, in testament to the suppleness of human intelligence, technologies have a way of supplementing, rather than simply replacing, one another.)?

Although at Zinio we think wide selection and discovering new content will change the way you read, we don?t expect it to completely replace your old habits. In fact we see that 15% of our readers use all three platforms to reach their magazines each month. All of which goes back to James Bennett?s point that technology definitely supplements rather than replaces consumer behavior and the same holds true with digital publishing. We?re with James Bennett and kudos to?The Atlantic.

HP to make $169 Android tablet, eschewing Windows

(AP) ? Hewlett-Packard Co. is making a tablet computer that uses Google's Android operating system, steering clear of Microsoft's latest tablet-oriented version of Windows, the company said Sunday.

The HP Slate 7 will have a 7-inch screen, making it similar in size to the Amazon Kindle Fire. It will cost $169 when it goes on sale in April in the U.S.

Most tablet makers, including Samsung and Amazon, have chosen Android as the best and cheapest operating system for products that can compete against Apple's iPad. HP previously made a tablet based on Palm's WebOS software, but the effort fizzled. The company also makes a more powerful tablet with PC-type components for the corporate market, which runs a PC-style version of Windows 8. It hasn't produced a tablet using Windows RT, Microsoft's product for iPad-type tablets.

"When we looked at creating a real killer product for consumers, a very portable, very entertainment-focused device, we thought that Android was the better choice," said Alberto Torres, who signed on as head of HP's mobile devices division five months ago. Previously, he worked for cellphone maker Nokia Corp. "Of course, we continue to work closely with Microsoft on other products as well."

Torres didn't rule out using Windows RT in the future, saying the company plans a broad portfolio of tablets tailored toward different types of buyers. But HP's choice of Android for a consumer device and Windows 8 for a corporate tablet leaves little room for Windows RT, which Microsoft hopes will expand the reach of Windows beyond corporate tablets.

Torres said the Slate 7 will use a relatively "vanilla" version of Android. The company is avoiding the interface modifications Asian manufacturers apply and the deeper changes imposed by Amazon and Barnes & Noble for their tablets. The Slate 7 will ship with the ability to talk to printers, HP's forte. At $169 the device is aggressively priced, costing half of what Apple charges for an iPad mini.

HP made the announcement on the eve of Mobile World Congress, the wireless industry's annual trade show, which starts Monday in Barcelona, Spain.

Competitor Samsung Electronics announced a new tablet earlier Sunday, to launch in the April to June time frame. The Galaxy Note 8.0 will be slightly larger than the Slate 7. It will run Android and accept pen input.

Samsung's comically large Galaxy Note 8.0 smartphone: purely a brand play, if nothing else

Samsung's comically large Galaxy Note 80 smartphone purely a brand play, if nothing else

The doors to this year's Mobile World Congress have just barely been opened, but you might say the show is already won. And, perhaps unsurprisingly, it's Samsung doing the winning. For those who were far too busy enjoying their Saturday evenings to notice, I should point out that Samsung has just taken the wraps off of the world's largest smartphone. The global version of Galaxy Note 8.0's fantastically (hilariously?) large display is indeed embedded onto a device that will not only surf the soothing waters of the world wide web, but also make phone calls for those brazen enough to toss it upside their noggin'.

The question, obviously, is "Why? But as I let the announcement wash over me, the answer became all too clear: "Because it can."

On Telstra cable at home and I find I need to specifically connect to the https site else it will fail half the time. So long as I choose https it works fine though, slightly annoying seeing as I would like it to always load the https site without me having to specify but I suspect that is more my needing to tidy up an old bookmark or something.

I have commented on this Facebook thing last week. It seems If you go to http it will fail a few times before working, but if you use https directly it works.

It sounds like the TelstraClear cache farm is at it again.

It sounds like the TelstraClear cache farm is at it again.

Im on Vodafone/Ihug and I've had the odd slowdown to zero nothing zlich when using facebook in the past couple weeks as well.

I was leaning to think it could be something related to the broken Perth - Asia cable, but seeing it always work on HTTPS but almost never on HTTP pretty much excluded that...

Hi everyone. We?ve looked into this and the network is operating to spec, and traceroutes don?t show any issues. We?ve also checked Facebook ourselves and have not experienced problems with load times on either Internet Explorer or Firefox. I've personally not noticed any issues at home on cable either, across three Windows devices and two Andriod.

Cheers, Gary

It is most definitely these 4 customer's local set ups - especially Mauricio's...lol

Seriously though, we see these sorts of things happen on TCL connections all the time. It is amazes me this issue is still apparent! You would really think TCL would get on to their caches and fix things up.

FYI - we are wellington home cable for TCL and like others facebook has been real bad recently.

it hangs at a redirect screen for "facebook static.ak.fbcdn.net"? which seems to be management of static content.

interesting as seems to be a issue for lots of facebook users overseas.

my family members are also reporting?there are a few international sites such as Amazon that they say are slowing down recently so I wonder if this is linked.

FYI - not a PC issue as is new and I regularly check for TSR bloat and?trogans.?

Gary thanks for looking, but this is intermittent and it may be working for you now, but give some time and it will stop working again - as it happened to D1023319.
