YouTube for iOS adds send-to-TV pairing, lets you skip the media hub

YouTube for iOS adds sendtoTV, lets you skip the media hub

Those running the dedicated YouTube app for iOS have had TV streaming for awhile... as long as there was an Apple TV in between. Google's video division is cutting out that middleman with its newly available app update. Similar to what we've seen in the Android software, iOS device owners can at last pair directly with some TVs, the PS3 or Xbox 360 to play and queue videos, even if there's multiple iPads and iPhones jockeying for attention on the same WiFi network. If your set is left out, YouTube still offers reasons to upgrade -- there's a connection to YouTube Capture for recording, and better playback on a pokey WiFi connection. As long as you're at least curious about TV streaming beyond Apple's set-top box, it's arguably worth trying.

Why Our Edcamp Failed - Finding Common Ground - Education Week

"We always talk about how failure is good but never give examples of how we actually fail." Jessica Johnson

On December 1st 2012, educators from around the state of New Jersey got together for an Edcamp. For months leading up to the event there was a buzz on social media. Teachers, principals and other staff that work in schools were Tweeting how they couldn't wait for the Saturday event. From an outside perspective, it was a very successful edcamp. They had presenters, participants and prizes. As a neighbor to the north, I was green with envy.

As a fan of professional development I love when teachers and administrators share best practices, which is probably why I am hooked on Twitter. In the district where I am a principal, I have created a couple of inservices where teachers shared their best practices and it was an awesome experience. The collective thoughts of a group are much more engaging and powerful than the thoughts of one person in the front of the classroom.

Given the power of Edcamp New Jersey, I decided to take a risk and create an edcamp for the school district where I work. As an elementary school principal, it's intimidating to put myself out there for the whole district because if it failed, I was worried I would take it personally. Plus, the staff in other schools don't know me like my staff does.

In preparation, I wrote a blog called Edcamps; The New Professional Development and used it as a blueprint as a plan for our district edcamp. In the blog I wrote,

"Money is short, and many of us have always believed that our best resources are within our own schools...or we probably wouldn't have hired them in the first place. Schools can create their own Edcamp for teachers and administrators within their district. If the district is too large, they can be separated by elementary, middle and high school. The best thing about an Edcamp is that they are open to the flexibility of the person organizing the event."

There was only one problem...it failed.

Jessica Johnson, an elementary principal in Wisconsin and an important member of my PLN, once said in a Tweet that "we always talk about how failure is good but never give examples of how we actually fail." So in an effort to help you succeed, and perhaps help me succeed the next time, I wanted to provide the steps I took on my Titanic-type voyage to a district-wide Edcamp.

The Plan
In late September/early October I spoke with the K-12 admin team about doing an Edcamp. I already spoke to Lynn, our Director of Technology and a person who constantly helps stretch my thinking. Lynn was highly supportive of the Edcamp and her two-member team began coming up with ideas of what we could do. They went off to their tech-cave and began hashing a plan.

I put out an e-mail to the whole district and said when the first meeting of the Edcamp team would take place. I used my edcamp blog as a reference along with other resources so they understood what an edcamp was because some people had never heard of one. At the first meeting, 12 people showed up. It was a mixture of technology staff (there are only 3 of them) district administration, building administration and teachers. Most of the teachers were the staff I work with every day so I appreciated their support.

In our meeting we came up with a date of Saturday, February 9th and decided to hold the edcamp from 9 am to noon. We wanted a mid-winter edcamp so people could get a break from the cold weather. Some of the committee members came up with the following ideas:
? Wordle - it combined all the words we could think of to describe an edcamp.

? Edcamp logo - we knew we needed to market the idea and every marketing campaign includes a great logo.
? Webpage - we wanted a place where people could go to read resources and get a feel for an edcamp so they wouldn't be intimidated to attend or present.
? E-mail address - We created an address where people could send their presentation ideas or interest in participating.
? In-service credit - We offered inservice credit for those staff members who attended and doubled it for those who presented.

For all intents and purposes, we thought our district-wide edcamp would be successful. After all, it was a trending idea in many states around the country. Unfortunately, over a two month period we heard from about 8 people who said they would attend, and most of those were on the committee. One person wondered if an administrator would present, and two teachers said they would present. After a couple of months, a few reminder e-mails, and a final deadline to present, we cancelled the edcamp. So, why did it fail?

What Happened!
Like usual, I consulted with the teachers I work with every day. We always have open dialogue about our success and failures. The following were some of the issues they had and others that I came up with through my own reflection.

? Timing - I started the edcamp campaign at the end of September/early October which was the same time teachers finished completing their first ever state-mandated Student Learning Objectives (SLO). They didn't have time to consider attending and presenting.

? Accountability - This school year has been like no other because of the accountability we are all under. It's not an excuse but a reality. Teachers feel stifled and worry about doing one more thing. At a time when we should be inspiring creativity, accountability is killing it for some people.

? The Common Core (CCSS) - This was the first year in the CCSS implementation for certain grade levels and they are more concerned about doing the Common Core correctly than trying to present at an edcamp.

? Burnout - The year began with so many state-mandated accountability measures that people just didn't feel like doing one more thing, regardless of whether it was a good idea or not.

? Social Media - One of the reasons why edcamps are trending ideas around the country is because they are being done at a state-level, not necessarily a district-level. Social media plays a huge part in it because most of the attendees and all of the presenters are on Twitter and the excitement builds naturally over months through those on-line conversations.

We will try a district-wide edcamp again because our committee heard from staff after it was cancelled. Ironically, upstate New York was hit with a huge snowstorm through the Saturday the edcamp was supposed to take place, so it would have been cancelled any way. However, as we all know, we can learn many important lessons through failure, and I definitely learned some things through this one.

T-Mobile USA revenue drops 5.2 percent to $4.9 billion for Q4 2012, customers and income also fall

TMobile revenue drops 10 percent to $41 billion, customers and income down, too

Is it a good thing that T-Mobile's US operation is in the crosshairs of a MetroPCS merger? We'll see, but meanwhile the operator again shed revenue, customers and profit in Q4 2012. Total revenue dropped during the quarter to $4.9 billion from $5.2 billion last year, while income was down a whopping 25.1 percent to $1.05 billion year-over-year. Meanwhile the company lost 515,000 branded contract customers compared to 492,000 last quarter, representing a 'churn' rate of 2.5 percent in that category, a slight improvement over last year. All that culminated in a rather miserable year for the carrier, which earned $424 million less than in 2011 ($4.9 billion), while showing a total loss of $6.4 billion thanks to depreciation and impairment charges. Meanwhile, parent Deutsche Telecom said recently that MetroPCS would merge with T-Mobile as early as April -- which sounds like it can't come soon enough.

Natural ways to manage spring allergies

Millions suffer from these bothersome indoor/outdoor allergies, but before you pick up the usual prescription or over-the-counter remedy, here are a few natural ways to manage the common symptoms of incessant coughing, runny nose, itchy eyes and sore throat.

While pollutants like asbestos and smoke fumes, as well as seasonal conditions like dust, pollen and mold spores contribute to respiratory allergies, "this type of allergy often occurs when the body has an excess accumulation of mucus, which harbors environment irritants," says Dr. Lindsey Duncan, ND, CN.

"Common drugstore medications generally mask symptoms and also have a rebound effect ? the more you use them, the more you need them," Dr. Duncan warns. "When taken for long periods, steroid drugs do not cure and often make hay fever allergies worse by depressing immune defenses and impeding allergen elimination."

Detox your diet

fish oil

To alleviate allergies, Dr. Duncan advises we eat non-mucus-forming foods such as fresh vegetables and fruits, whole grains, foods with active cultures (like yogurt), foods high in vitamin C like citrus and berries, oily seafood and sulfur-rich cabbage, onions and garlic.

This suggested program "will help detoxify your blood, support your liver, neutralize histamine reactions and neutralize allergen response," she says.

Additionally, get plenty of essential fatty acids from omega-3 oils like flax, sea greens and spinach. Avoid inflammatory preserved and canned foods, sugary foods, caffeine and fatty mucus-forming foods (especially dairy products). Fasting can also assist in clearing allergy symptoms.

Naturopathic doctor Thalia Farshchian?s favorite seasonal allergy cure is drinking three to five cups of nettle tea throughout the day.

"This natural anti-histamine helps the liver detoxify allergens more efficiently and significantly reduces symptoms," Dr. Farshchian says. Other herbs that support avoiding allergies include dandelion (also found in tea form) and milk thistle.

Dr. Elizabeth Trattner, AP, DOM recommends boosting your immune system with fish oil at least one month before allergy season starts.

"Studies have demonstrated that fish oil is an excellent natural anti-inflammatory. Look for fish oil with high doses of EPA, one of the acids in fish oil that decreases inflammation," says Dr. Trattner.

She says to take at least 2,000 mg of EPA a day, with food, before 3 p.m. since "fish oil can cause insomnia in approximately 10 percent of the population who consumes it."

But if you don?t fancy fish oil supplements, go straight to the source and eat oily fish like salmon, mackerel, herring, sardines and albacore tuna, which are loaded with omega-3 fatty acids,?two to three times per week.

Clean up your environment

One simple way to avoid an allergic reaction is to keep your bedroom free of pollen and dust. Dr. Trattner recommends investing in a good HEPA filter to purge the air in the bedroom of mold spores, pollen, pet dander, smoke and dust.

She also advises removing the shoes and clothing you wear during the day before you enter the bedroom; decluttering so dust is less likely to collect on the carpet and drapery; and using only natural and unscented household products, dryer sheets, shampoos and laundry soap to decrease the chemical load on your body.

Pet owners should bathe and brush their furry friends frequently because "their fur can hold on to pollen and other allergens that can exacerbate your allergies."

CigaretteMake necessary lifestyle changes

It sounds like common sense, but allergy suffers may need a gentle reminder to stop smoking and to avoid secondary smoke. "[Smoke] magnifies allergy reactions," says Dr. Duncan.

Regular exercise helps boost the immune system, so incorporate a variety of physical activity into your routine including cardiovascular exercise, yoga and tai chi. During allergy season, however, Dr. Trattner recommends you work out indoors to lower your exposure to pollen in the air.

For allergy relief, licensed acupuncturist and certified herbalist Lexi Hagenson recommends weekly acupuncture treatments for a month or two.

"This 3,000-year-old Chinese practice can remarkably improve quality of life for allergy sufferers, even those who don't see results from conventional anti-allergy medications," says Hagenson, who adds that relief can come after just one session.

"Acupuncture works both locally by [alleviating]?head, neck and facial symptoms, and throughout the body by promoting healthy circulation and decreasing areas of hypersensitivity and stagnation."

Use a neti pot three to five times a week

Yes, pouring a saline solution from that little pot into your nose can work wonders. A neti pot can be found in most health food stores; simply follow the directions on the package.

"For thousands of years, ayurvedic medicine has used this simple nasal irrigation system to soothe and protect nasal passages," says Hagenson.

"It's the most effective way to remove pollen, dust,?environmental irritants and mucus from your sinuses, without causing dryness or rebound congestion often experienced from pharmaceutical decongestants."

Stocks surge, Dow nears record high

NEW YORK (AP) ? The Dow came within 60 points of its all-time high Wednesday after rising sharply for a second straight day.

The market surged following more evidence that the Fed will keep interest rates low, housing will keep recovering and shoppers aren't pulling back on spending, though they're paying more in Social Security taxes this year.

The gains were broad: Twenty-nine of 30 stocks in the Dow Jones industrial average rose. All 10 industries in the Standard and Poor's 500 index climbed.

The Dow Jones industrial average closed up 175.24 points, or 1.2 percent, to 14,075.37. The index is now 89 points from its record close of 14,164.53 reached in October 2007. The index rose steadily from the opening bell, then peaked near the record at 3:26 p.m. Eastern Time, before easing slightly in the last half hour of trade.

The Dow has surged 290 points in the past two days, erasing its drop of 216 points Monday when inconclusive results from an election in Italy renewed worries that Europe's fiscal crisis could flare up again.

"The market psychology has clearly shifted. It's no longer sell the rally, it's buy the dips," said Dan Veru, chief investment officer of Palisade Capital Management. "The economic data continues to be strong."

The Standard and Poor's 500 index gained 19.05 points, or 1.3 percent, to 1,515.99. The Nasdaq composite rose 32.61 points, or 1.3 percent, to 3,162.26. The index is 6.5 percent higher for the year, and is about 3.1 percent short of its record close of 1,565.

Investors were also encouraged Wednesday that Federal Reserve Chairman Ben Bernanke stood behind the central bank's low-interest-rate policies as he faced the House Financial Services Committee. His comments dissipated worries about the bank's resolve to keep up the program. Those worries sprang up last week when minutes from the bank's last policy meeting revealed disagreement among Fed officials.

Also, the number of Americans who signed contracts to buy homes rose in January from December to the highest level in almost three years. The report continued a string of positive housing news. Sales of new homes jumped 16 percent last month to the highest level since July 2008, the government reported Tuesday.

Home builder stocks rose for the second day in a row. PulteGroup climbed 25 cents, or 1.3 percent, to $19.30, after rising 5.7 percent the day before.

"Some encouraging news for the bulls has been the housing data that has come out over the past couple of days," said Todd Salamone, director of research at Schaeffer's Investment Research.

The analyst said he remained "extremely bullish," on stocks in the medium and long-term, but cautioned that a pullback may lie ahead in coming days after the year's strong gains.

Stocks have surged since the start of the year. The Dow is up 7.4 percent and the S&P 500 has climbed 6.3 percent.

But rising even more is the Dow Jones transportation average, which is up 13 percent for the year to 5,989.37. Airlines like Delta and Alaska Air are powering the gains.

"If the economy is doing well you've got to be moving stuff around," said Phil Orlando, chief equity strategists at Federated Investors. "You've got to be moving people on airplanes, you've got to be moving cargo with trains or trucks, or UPS."

Discount retailers rose Wednesday. Dollar Tree jumped $4.31, or 11 percent, to $45.39 after reporting a 22 percent profit increase. Dollar General rose $1.61, or 3.6 percent, to $46.56. Family Dollar Stores rose $1.39, or 2.5 percent, to $57.68.

Earnings for S&P 500 companies will climb 7.8 percent in the fourth quarter, the third straight quarter of growth, according to data from S&P Capital IQ.

The yield on the 10-year Treasury note rose two basis points to 1.90 percent.

Among other stocks making big moves;

? Retailer J.C. Penney fell $3.07, or 15 percent, to $18.09 after the market closed following a much a quarterly loss that was much larger than expected.

? Priceline.com rose $17.42, or 2.6 percent, to $695.91 after reporting that its net income jumped in the fourth quarter as bookings grew.

? First Solar plunged $4.32, or 13.8 percent, to $27.04 after the company posted disappointing sales for the fourth quarter and gave a weak early outlook for the year.

? Target fell 93 cents, or 1.5 percent, to $63.12 after the No. 2 discount chain's quarterly income fell 2 percent as it dealt with intense competition during the holiday shopping season.

? DreamWorks Animation fell 30 cents, or 1.8 percent, to $16.31 after posting a loss of $82.7 million. The company booked a write-off on its November release "Rise of the Guardians" and on an upcoming movie that needs to be reworked.

Study reveals stem cells in a human parasite

Tuesday, February 26, 2013

From the point of view of its ultimate (human) host, the parasitic flatworm Schistosoma mansoni has a gruesome way of life. It hatches in feces-tainted water, grows into a larva in the body of a snail and then burrows through human skin to take up residence in the veins. Once there, it grows into an adult, mates and, if it's female, starts laying eggs. It can remain in the body for decades.

A new study offers insight into the cellular operations that give this flatworm its extraordinary staying power. The researchers, from the University of Illinois, demonstrated for the first time that S. mansoni harbors adult, non-sexual stem cells that can migrate to various parts of its body and replenish tissues. Their report appears in the journal Nature.

According to the World Health Organization, more than 230 million people are in need of treatment for Schistosoma infections every year. Most live in impoverished areas with little or no access to clean water. Infection with the worm (also known as a blood fluke) can lead to damaging inflammation spurred by the presence of the worm's eggs in human organs and tissues.

"The female lays eggs more or less continuously, on the order of hundreds of eggs per day," said U. of I. cell and developmental biology professor and Howard Hughes Medical Institute Investigator Phillip Newmark, who led the study with postdoctoral researcher James J. Collins III.

"The eggs that don't get excreted in the feces to continue the life cycle actually become embedded inside host tissues, typically the liver, and those eggs trigger a massive inflammatory response that leads to tissue damage."

Children are especially vulnerable to the effects of infection, in some cases experiencing delays in growth and brain development as a result of chronic inflammation brought on by the parasites.

The new study began with an insight stemming from years of work on a different flatworm, the planarian, in Newmark's lab. Collins thought that schistosomes might make use of the same kinds of stem cells (called neoblasts in planarians) that allow planarians to regenerate new body parts and organs from even tiny fragments of living tissue.

"It just stood to reason that since schistosomes, like planaria, live so long that they must have a comparable type of system," Collins said. "And since these flatworms are related, it made sense that they would have similar types of cells. But it had never been shown."

In a series of experiments, Collins found that the schistosomes were loaded with proliferating cells that looked and behaved like planarian neoblasts, the cells that give them their amazing powers of regeneration. Like neoblasts, the undifferentiated cells in the schistosomes lived in the mesenchyme, a kind of loose connective tissue that surrounds the organs. And like neoblasts, these cells duplicated their DNA and divided to form two "daughter" cells, one of which copied its DNA again, a process that normally precedes cell division.

"Stem cells do two things," Newmark said. "They divide to make more stem cells and they give rise to cells that can differentiate."

Collins had labeled the cells with fluorescent markers. This allowed him to watch how they behaved. He noted that over the course of a few days, some of the labeled cells migrated into the gut or muscle, to become part of those tissues.

"We label the cells when they're born and then we see what they grow up to become," Collins said. "This is not conclusive evidence that these cells are equivalent to the planarian neoblasts, but it is consistent with the hypothesis that they are."

The researchers went deeper, determining which genes were turned on or off, up or down in the proliferating cells as compared with the non-dividing cells. They identified a gene in the proliferating cells that coded for a growth factor receptor very similar to one found in planarians. When the researchers switched off the parasite's ability to make use of this gene (using a technique called RNA interference in worms grown in the lab), the proliferating cells gradually died out.

"We postulated that these cells are important for the longevity of the parasite," Collins said. "Now we can start asking which genes regulate these cells."

"We started with the big question: How does a simple parasite survive in a host for decades?" Newmark said. "That implies that it has ways of repairing and maintaining its tissues. This study gives us insight into the really interesting biology of these parasites, and it may also open up new doors for making that life cycle a lot shorter."
