If your teen’s lack of sleep is keeping you up nights, a new study should help put your mind at ease.
National guidelines recommend at least eight hours of serious snooze time a night for young people. But that’s an unrealistic goal for adolescents, who are overloaded with homework, extracurricular activities and part-time jobs, experts say. Or who feel the need to stay up late texting friends or updating Facebook.
In fact, if standardized test performance is any indication, 16-year-olds score best with about seven hours of sleep a night, surprising new research finds.
Brigham Young University economists Eric Eide and Mark Showalter — who are also dads — used a nationally representative sample of 1,724 students, comparing children’s and teens’ standardized test scores with the amount of sleep they reported.
Permian forest found preserved in volcanic ash
Buried beneath a coal mine in Mongolia, scientists have discovered a ‘Pompeii-like’ forest, 300 million years old, buried by volcanic ash.
Because volcanic ash covered a large expanse of forest over the course of only a few days, plants were preserved as they fell, in many cases in the exact locations where they grew.
“It’s marvelously preserved,” says University of Pennsylvania paleobotanist Hermann Pfefferkorn.
“We can stand there and find a branch with the leaves attached, and then we find the next branch and the next branch and the next branch. And then we find the stump from the same tree. That’s really exciting.”
The researchers also found some smaller trees with leaves, branches, trunk and cones intact, preserved in their entirety.
Because local coal mining has uncovered large tracts of rock, the researchers were able to examine a total of 1,000 square meters of the ash layer, spread between three different sites nearby.
The team has dated the ash layer to around 298 million years ago, the beginning of the Permian period.
Back then, the Earth’s continental plates were still moving toward each other to form the supercontinent Pangea, and the climate was comparable to today’s.
In each of the three study sites, Pfefferkorn and collaborators counted and mapped the fossilized plants they encountered. In all, they identified six groups of trees, some up to 80 feet high, with tree ferns forming a lower canopy.
The researchers also found nearly complete specimens of a group of trees called Noeggerathiales – extinct spore-bearing trees, relatives of ferns. While these have previously been found at sites in North America and Europe, they appear to be much more common in these Asian sites.
“This is the first such forest reconstruction in Asia for any time interval, it’s the first of a peat forest for this time interval and it’s the first with Noeggerathiales as a dominant group,” says Pfefferkorn. “It’s a time capsule.”
The Enemy Of My Enemy Is My Friend
Microsoft and Apple should hate one another right now. I mean, really hate each other. After decades of domination, Microsoft has watched their rival move from death’s door to become the most valuable company in the world — over $200 billion more valuable than Microsoft itself. And it was Microsoft who helped get Apple there, remember, with a timely cash infusion in 1997.
Steve Ballmer laughed off the iPhone, which eventually helped kill off Windows Mobile — and it’s now bigger than all of Microsoft’s businesses combined. And the company shrugged off the iPad, even as it established a category, tablets, which Microsoft itself had been trying to establish for years.
Now Apple’s iOS ecosystem threatens the very fabric of Microsoft. Given the rise of the iPhone and iPad, and the halo-effect they’re having on the Mac, products like Windows and Office don’t hold the same importance that they once did in the computing world. And their shine is ever-diminishing. People are realizing that they just don’t need them anymore. Apple’s rise is slowly killing the Microsoft we’ve all known for years.
And yet, Microsoft rarely bashes Apple publicly anymore. In fact, they often take their side on arguments or come to their defense on issues. Again, these were once bitter rivals. And these times should be the battleground for their bloodiest battles yet. Instead, it’s all holding hands, s’mores, and Kumbaya.
Why? Because Microsoft has an enemy they hate much worse than Apple. And Apple has the same enemy. Google.
This is nothing new, but the animosity continues to build between the parties. Look at the news today, for example. Following last week’s headlines that Google was bypassing privacy settings in Apple’s mobile Safari browser, Microsoft today says that Google is doing the same thing to their own IE browser. Meanwhile, Google says that Microsoft is full of shit, while Apple is probably off in the corner smiling.
It wasn’t long ago that Apple and Google were aligned against Microsoft. Remember, then-Google CEO Eric Schmidt was on Apple’s board and the two sides worked closely on projects like the original iPhone. Then Android came along and destroyed that relationship. While Google probably didn’t consider it at the time, this set the stage for Microsoft and Apple to align on things like the Nortel patents.
Microsoft should probably be going all-in to combat the rise of iOS, but instead they seem far more concerned with spending obscene amounts of money to bolster Bing as a Google competitor. And they seem to truly enjoy undermining Android by way of licensing agreements with key OEM partners.
Meanwhile, Apple seems downright bored if you ask them about Microsoft as a competitor. But ask about Google (Android in particular) and the knives come out.
Maybe this all just means that Google is doing something right. They have all the biggest technology companies in the world pointing guns right at them. You don’t get to the top without pissing off people along the way. But the way Google has managed to unify all of these main rivals against them should at the very least give them pause. Microsoft and Apple are the two biggest examples. But Facebook and Twitter are finding common ground against Google as well thanks to the search giant’s foray into the social realm.
All of this makes for a fascinating situation in the tech world. On one side there’s Google. On the other side there’s basically everyone else, with new members seemingly joining on a daily basis. And this side is filled with rivals that under any other circumstance would hate each other. But here they’re allied. The enemy of my enemy is my friend.
Age, income dial up smartphone ownership rates
Based on age alone, it would not be news that younger consumers are much more likely to own a smartphone than older consumers. But when you throw income into the equation, it becomes a completely different story.
To start off, overall smartphone penetration stood around 48 percent domestically by the end of January, according to a new report from Nielsen Wire.
The age group with the highest levels of smartphone ownership was the 24- to 34-year-old demographic with 66 percent of respondents acknowledging that they own a smartphone. In fact, 8 out of 10 people in this group got them in the last three months.
However, when income was taken into account, consumers between the ages of 55 and 64 with salaries of more than $100,000 per year made up the difference and were almost as likely as those in the 35- to 44-year age group making only $35,000 to $75,000 annually.
Smartphones aren’t really cheap commodities. On average, they cost $199 with the requirement of a two-year service agreement, data plans, and more. That can add up to several hundreds of dollars extra within a few months.
If you don’t want to deal with all of that, then you have to fork over around $599 or $699 for an unsubsidized device–and then you still have to pay for some kind of service plan (pay-as-you-go, etc.) afterwards.
Thus, a smartphone is an investment at any age, any income.
But the takeaway point here (especially important to anyone trying to sell these devices, ranging from marketing departments to the developers) would be that younger generations care more about the technology and are more likely to pay a high price regardless of the income, while older generations will probably only pay for these advanced devices if they have the extra income to do so.
For reference, the Nielsen report is based upon the responses of more than 20,000 mobile consumers in the United States who were surveyed in January.

10 Steps To Smartphone Privacy
Your smartphone is simultaneously your best friend and your worst enemy. It can help you find the nearest Starbucks for a caffeine fix, reach out to loved ones in times of need, or get the score of that vital play-off game. If it falls into the wrong hands, heck, even if it doesn’t fall into the wrong hands, a smartphone can expose your contacts, location history, banking data, and more. Smartphone privacy was in the news again this week, due to a fresh Google and Apple iPhone privacy flap.
This all means smartphone owners need to be vigilant in order to protect themselves. Here are some essential tips to help keep your vital data under control.
1. Lock Your Phone
This may seem a simple and obvious step to take, but many people are too lazy to do it. Set up a screen lock so the phone can’t be accessed or used without a password of some sort. Though four-number pins may foil street hoods, using a real alphanumeric password is much better. Make sure the screen locks automatically after 1 to 5 minutes of non-use.
2. Use ‘Find My iPhone’ Or Similar Services
It only takes a few moments to use today’s smartphone tools to set up a free tracking/wiping service. Android, BlackBerry, iOS, and Windows Phone devices allow users to lock, track, or wipe their phones remotely if lost. Not only does this protect your data, it could help you recover a lost/stolen device. Do it.
3. Don’t Leave Your Smartphone Unattended
Would you leave your social security card on a bar while you traipse off to use the bathroom? I didn’t think so. Don’t leave your phone sitting around in public where it can be grabbed by an opportunist. You may trust your coworkers in the meeting room, or friends you invite to your home, but don’t be too quick to extend trust to people you don’t know. Put it in your coat, pocket, desk (yes, even at the office), briefcase, purse, backpack, wherever. Keep it out of view.
4. Don’t Give Your Phone to Strangers
That ‘tourist’ who needs to make an emergency call home and asks to use your phone? Dicey. It could certainly be someone in legitimate need of help–or not. Rather than give the person your phone, make the call yourself, and put it on speakerphone.
5. Keep Your Smartphone Up-to-Date
You know that system update you’ve been ignoring for a couple of weeks? Install it. Nearly all smartphone system updates include enhancements to device security. Smartphone makers and carriers often ship phones with buggy software that contains loopholes that can be used to circumvent security. When updates are provided by the manufacturer, install them.
6. Manage Location Settings
Most phones come with either GPS or carrier-aided location tracking features. These are meant to enhance the functionality of applications such as Google Maps or Foursquare (after all, maps are kind of useless if you don’t know where you are.) Now, however, there are thousands of apps that want to access your location data, such as Google+, Facebook, Twitter, Instagram, and others. You can control location settings in these apps individually in most cases. If you want to make your location as secret as possible, turn off all forms of location assessment. This way, apps won’t know where you are.
7. Do App Due Diligence
Speaking of apps, do your homework. If you value your privacy, read the “Permissions” screen when you download and install apps. Many apps will let you know that they are accessing your location, call history, contacts, and other data. Be sure to note if that data is going to be stored by the app, delivered by the app to the app vendor, or sent to third-party companies for other uses. If you’re suspect about the permissions, do some research, look online to see if the app has been reviewed by reputable sources, and so on. Also, if you download an app and stop using it, get rid of it. Don’t leave it on your phone.
8. Don’t Download Apps From Untrusted Sources
Most smartphone manufacturers only want you to download apps from their stores, but there are plenty of ways to circumvent this control. In Android smartphones, for example, you can choose to enable a setting that allows non-Market apps to be installed. If you jailbreak our iPhone, you can install Cydia apps, etc. Don’t do it. Apps that haven’t been approved by an official app store are more likely to be invasive.
9. Watch Those Attachments!
Being able to access email on my phone is vital, especially when I am traveling for work. Be careful, however, about opening the attachments sent to you by people you don’t know. Take the same precautions on your smartphone that you would on your home computer. Same goes for downloads from web sites, social networks, shortened URLs, etc.
10. Encrypt Smartphone Data
Today’s smartphones make it relatively simple to encrypt the contents of the phone. This ensures that even if the phone does fall into the wrong hands and is accessed because the screen lock was bypassed, some level of protection remains. This is especially important for the memory cards of Android smartphones. The phone itself doesn’t have to be stolen in order for you to lose all your documents, photos, songs, and other files.
The smartphone privacy bottom line is the same one your mother taught you when you were growing up: Don’t trust strangers (or strange companies, apps, or networks.)
Panasonic announces its Eluga smartphone
JAPANESE HARDWARE VENDOR Panasonic has unveiled its Eluga smartphone that is bound for Europe.
The Eluga signifies the firm’s return to the European market after a number of years of focusing on its home market. It said it is “back with a splash” with the Eluga, which it says stands for ‘elegant user-oriented gateway’.

Toshiya Matsumura, GM and head of Mobile Communications for Panasonic Europe said, “Despite the unprecedented increase in the number of smartphone devices appearing over the last few years, we don’t believe anyone has yet managed to truly bridge the gap between style and substance.”
“With the launch of the Eluga, we’re aiming to prove it is possible to deliver style, function, form, and the very best underlying technology, all in a competitively-priced package.”
The Eluga might not have the best name for a smartphone but it comes packed with mouth-watering technology. For starters, it will have a 4.3in organic LED (OLED) qHD touchscreen.
It will be powered by a Texas Instruments OMAP4430 1GHz dual-core processor and have 1GB of RAM, 8GB of internal storage and an 8MP rear facing camera. Unfortunately it will ship with Android 2.3.5 Gingerbread with an upgrade to Android 4.0 Ice Cream Sandwich coming after launch.
Panasonic says the device will have a slim 7.8mm profile and has a few tricks up its sleeve including near field communications (NFC) and digital living network alliance (DLNA) technology. It will also be water and dust proof.
The firm said the Eluga will be available in April but hasn’t announced a price yet.
Nvidia’s first ‘complete’ smartphone: ZTE Mimosa X
Nvidia’s Tegra 2 system-on-a-chip architecture has thus far been used in a handful of high-end Android “superphones”: Motorola Atrix 4G, Photon 4G, LG Optimus G2X, and the Samsung Captivate Glide, to name a few.
Today, Nvidia and Chinese smartphone maker ZTE announced the Mimosa X, the first Android smartphone to use Nvidia’s products for both applications processing and wireless communications since the company acquired wireless modem maker Icera last June.
A Top German Environmentalist Cools On Global Warming
Hell has finally frozen over! Fritz Vahrenholt, one of the fathers of Germany’s environmental movement who has headed the renewable energy division of RWE, that country’s second largest utility company, has co-authored a new blockbuster book with geologist/paleontologist Sebastian Luning announcing that the climate catastrophe heralded by the U.N.’s Intergovernmental Panel on Climate Change (IPCC) has been called off. Titled “The Cold Sun: Why the Climate Disaster Won’t Happen”, it raises a man-made blizzard of icily numbing challenges to IPCC competence in general, and to their exaggerated attributions of CO2 greenhouse warming influence in particular.
Such charges from a prominent socialist and former global warming doctrine apostle have really taken the alarmist community by storm…and their symbolic timing as Germany has been experiencing its worst cold snap in 26 years made the message even more dramatic. Three of Germany’s most widely read news publications, Bild, Der Spiegel, and Die Welt immediately took notice, releasing skeptical climate science articles in their print and on-line editions.
The initial Bild article titled “The CO2 Lie” addressed “What the IPCC of the U.N. doesn’t tell you”, and then asks, “…what if the IPCC is wrong? Can we really blindly trust these experts? Are they really independent?” They then conclude, “The phenomenal prognoses of heat from the IPCC are pure fear-mongering.” Part 2 titled “There Hasn’t Been Any Global Warming In 12 Years!” emphasizes that CO2 is not that potent of a gas, and that a doubling would lead to only a 1.1°C temperature increase. Yet the IPCC fudges the models so that they produce a much higher increase because of the assumed water-vapor amplifier. This assumption is really on shaky ground.
Bild notes that while soot also is a major contributor and that a recent study shows that it was seriously underestimated just a few years ago, “…the IPCC decision-makers are fighting tooth and nail against accepting the roles of the oceans, sun, and soot.”Accordingly, IPCC models are completely out of whack. “The facts need to be discussed sensibly and scientifically, without first deciding on the results.”
Germany’s flagship weekly news magazine Der Spiegel featured a 4-page interview with Vahrenholt, where he repeated book statements that IPCC scientists exaggerated the impact of CO2 on climate. He predicted that taking CO2’s true influence into account and extending past natural cycles into the future would most likely produce a few tenths of a degree of cooling. And although the book authors don’t deny that CO2 has some warming influence, they believe the Sun plays a far greater role in the whole scheme of things.
In a full page Die Welt interview, Vahrenholt explains why he grew skeptical of the IPCC. One problem was that the IPCC had the habit of filtering out important scientific findings so that they never appear in the summary reports. He also gives three reasons why he expects it to get cooler in the future: 1) we are or soon will be beginning on the downward flank of the Sun’s Gleissberg and Suess cycles, 2) the ocean cycles will be in their negative phases over the next decades, and 3) we currently find ourselves in the weakest phase of solar activity in 80 years, and the next solar cycle could be a very weak one.
Dr. Vahrenholt’s lack of trust in the IPCC’s objectivity and veracity took root two years ago when he became an expert reviewer for their report on renewable energy. He recently commented: “I discovered numerous errors and asked myself if the other IPCC reports on climate change were similarly sloppy.” When he pointed out the inaccuracies to IPCC, their officials simply brushed them aside. Stunned by this, he asked himself “Is this the way they approached climate assessment reports?”
After carefully studying the matter Vahrenholt decided, “ I couldn’t take it any more. I had to write this book.” He explains that then after digging into the IPCC’s climate report he was horrified by what he found. On top of discovering numerous factual errors there were issues involving 10 years of stagnant temperatures, failed predictions, Climategate e-mails, and informative discussions with dozens of other elite skeptical scientists. The book cites more than 800 sources to back up conclusions, including many peer-reviewed papers that appeared after the IPPC’s 2007 report was released.
Vahrenholt and Luning aren’t the only leading German climate scientists to find that IPCC’s global warming projections are exaggerated. In 2001 Hans Joachim Schellnhuber, the director of the Potsdam Institute for Climate Impact Research who serves as the German government’s climate protection advisor, co-authored a paper refuting reliability of Global Climate Models upon which their alarmist projections are based. It stated: “We analyze temperature records of six representative sites around the globe simulated by the models for two scenarios: 1) with greenhouse gas forcing only, and 2) with greenhouse gas plus aerosol forcing. We find that the simulated records for both scenarios fail to reproduce the universal scaling behavior of the observed records and display wide performance differences. The deviations from the scaling behavior are more pronounced in the first scenario, where also the trends are clearly overestimated.”
More recently Schellnhuber admitted in a speech before agricultural experts that “warmer temperatures and high CO2 concentrations in the air could very well lead to higher agricultural yields.”
While Vahrenholt and Luning have found no evidence of any coming CO2 climate catastrophe, they continue to believe in switching to renewable energy sources, but doing so in a rational “work fast, but don’t hurry ”manner. In the Die Welt interview Vahrenholt comments that Germany’s 25,000 megawatt solar capacity and 29,000 megawatt wind capacity are very volatile sources that require conventional power plants to balance out power supply.
The weather-dependent, sporadic nature of those “renewable” energy sources has already begun to wreak havoc on Germany’s power grid, and threatens to destabilize others all across Europe. After tens of billions of euros have been spent on these systems, raising consumer electricity prices in the process, not a single coal or gas-fired power plant has been taken off line. Ironically, Germany, once a net power exporter, now imports electricity from French nuclear facilities and fossil-powered plants in neighboring countries. They became an importer after their government closed 8 of the older 18 nuclear reactors in the fearful aftermath of Japan’s Fukushima disaster.
Obama wants $2.1 billion for NASA’s Florida spaceport
Barack Obama’s proposed 2013 budget for NASA boosts spending at
the Kennedy Space Center, which bore the brunt of job layoffs at
the end of the space shuttle program last year, the center
director said on Tuesday.
The president’s $17.7 billion budget request for NASA for
the year beginning Oct. 1 includes $2.1 billion for the Florida
spaceport, an increase of $323 million over this year’s budget.
“During these austere times when other centers went down,
for us to go up I think says a lot about the importance of what
we’re doing and where we’re going,” Kennedy Space Center
director and former astronaut Bob Cabana told a National Space
Club Florida Committee meeting in Cape Canaveral on Tuesday.
The center’s proposed budget increase won’t mean more NASA
jobs, however. Cabana told reporters he expects Kennedy Space
Mediterranean Diet Good for Small Brain Vessels
The Mediterranean diet continues to reveal its bounty of health benefits — this time protecting against damage to small blood vessels in the brain, researchers found.
In a cohort study, each one-point increase in a Mediterranean diet rating score was associated with a significantly lower volume of white matter hyperintensities on MRI (P=0.01), Clinton Wright, MD, of the University of Miami, and colleagues reported in the Archives of Neurology.
The benefits may spring from the diet’s heavy reliance on monounsaturated fats, such as olive oil, since such fats were shown in adjusted analyses to predict white matter hyperintensity volume.
The findings “add to a growing body of literature that a Mediterranean diet may be protective against subclinical vascular damage,” Wright and colleagues wrote.
Studies have shown that the Mediterranean diet lowers the risk of heart disease, stroke, cognitive disorders, and other vascular events, but no studies have examined the relationship with white matter hyperintensity volume — a marker of chronic small-vessel damage.
A better understanding of modifiable risk factors for small-vessel damage may help prevent stroke and cognitive decline, the researchers wrote.
So they conducted a cross-sectional analysis within a longitudinal population-based cohort study, the Northern Manhattan Study (NOMAS), using a food frequency questionnaire to assess dietary behaviors.
Among 1,091 patients, 966 had dietary information available and were included in the analysis.
Mean patient age was 72 and white matter hyperintensities were assessed via MRI. The researchers also calculated a Mediterranean diet score based on a scale of 0 to 9 points.
Overall, women were less likely to eat a Mediterranean diet than men, and those who reported more physical activity or a lower body mass index [BMI] had higher Mediterranean diet scores.
Wright and colleagues found a trend toward more white matter hyperintensities among those with lower Mediterranean diet scores, but it wasn’t significant (P=0.07).
Yet each one-point increase in Mediterranean diet score was associated with a lower log white matter hyperintensity volume, they reported (P=0.01).
In adjusted analyses, the only component of the Mediterranean diet that was an independent predictor of white matter hyperintensity volume was the ratio of monounsaturated to saturated fats (P=0.001).
Thus, the ratio of monounsaturated to saturated fats may be “the most important component” of the diet in predicting small vessel damage, they said.
While previous studies have shown moderate fish and alcohol intake to be protective against white matter abnormalities, they noted, these components weren’t independent predictors of hyperintensities in their study.
Other variables associated with hyperintensity volume in their study included:
- Age at MRI (P<0.001)
- Black race (P<0.001)
- Hispanic ethnicity (P=0.02)
- Diastolic blood pressure (P=0.01)
- BMI (P=0.01)
- Interaction between diastolic blood pressure and antihypertensive drugs (P=0.02)
Wright and colleagues emphasized that the overall intake of fruits, vegetables, fish, and cereals was lower in their study than in others — especially those conducted in Spain and Greece — and may be able to as closely reflect a true Mediterranean diet.
They also cautioned that white matter hyperintensities are etiologically heterogeneous, and can include neurodegeneration as well as small vessel damage.
Another limitation was that diet was only assessed at baseline, an averages of seven years before the MRIs were done, and dietary patterns could have changed during that time.
Thus, they called for replication of their results in future population-based studies.
