Over 7.1 million students take online college classes, but growth fades
Posting in Technology
The number of higher education students in the United States taking at least one online class grew to more than 7.1 million in the fall term of 2012, according to the latest numbers from Babson Survey Research Group and its 2013 Survey of Online Learning.
But even though online higher education is growing at a rate of 6.1 percent from the previous year, it is the lowest annual rate since the survey began tracking online enrollment in 2002. So has online course enrollment plateaued?
"The evidence continues to mount that a plateau for online enrollments may be approaching, but there is no evidence that it has yet arrived," the report said.
Still, online courses are becoming an increasing part of the learning mix for higher education students. Now, 33.5 percent of higher ed students take at least one online class, an increase from less than 10 percent in 2002.
Other statistics from the study:
90 percent of academic leaders believe that it is likely or very likely that a majority of all higher education students will be taking at least one online course in five years.
The proportion of chief academic leaders that say online learning is critical to their long-term strategy dropped from 69.1 percent to 65.9 percent.
The percent of academic leaders rating the learning outcomes in online education as the same or superior to those in face-to-face grew from 57.2 in 2003 to 77.0 percent last year, but fell back to 74.1 percent this year.
How do MOOCs fit in?
For all the attention massive open online courses (MOOCs) get, only five percent of higher education institutions are taking advantage of the platform (double the number from the previous year) to "increase the visibility of the institution" and to "drive student recruitment" -- the two main reasons institutions said they offer MOOCs.
But even as MOOCs grow, academic leaders are becoming more pessimistic about their long-term sustainability. Of the chief academic officers surveyed in 2012 30 percent said they believe MOOCs are sustainable. Last year that number decreased to 22 percent.
That's hardly a surprise as only four percent of MOOC participants finish a course, on average, and they are distributed for free -- only now has one tried adding a tuition fee. Even Sebastian Thrun, cofounder of Udacity, has said of MOOCs, "We have a lousy product."
Meanwhile, researchers are going back and forth over the effectiveness of online courses, in general, versus the traditional classroom model. As Doug Lederman puts it on Inside Higher Ed:
The discipline of research on online learning is nascent enough, and the body of long-term studies thin enough at this point, that keeping tabs on the state of thinking is a bit like watching a table tennis match. Every study that provides evidence of the effectiveness of online teaching seems to elicit a critical one. And vice versa.
Americans surveyed by Gallup last year had mixed feeling about online education. Many believe online education provides a better value and curriculum choice than traditional classrooms but still think online learning falls short in academic rigor.

This sounds very promising and could be implemented quite easily.

Researchers harness sun's energy during day for use at night

Solar energy has long been used as a clean alternative to fossil fuels such as coal and oil, but it could only be harnessed during the day when the sun's rays were strongest. Now researchers led by Tom Meyer at the Energy Frontier Research Center at the University of North Carolina at Chapel Hill have built a system that converts the sun's energy not into electricity but hydrogen fuel and stores it for later use, allowing us to power our devices long after the sun goes down.

"So called 'solar fuels' like hydrogen offer a solution to how to store energy for nighttime use by taking a cue from natural photosynthesis," said Meyer, Arey Distinguished Professor of Chemistry at UNC's College of Arts and Sciences. "Our new findings may provide a last major piece of a puzzle for a new way to store the sun's energy – it could be a tipping point for a future."

In one hour, the sun puts out enough energy to power every vehicle, factory and device on the planet for an entire year. Solar panels can harness that energy to generate electricity during the day. But the problem with the sun is that it goes down at night—and with it the ability to power our homes and cars. If solar energy is going to have a shot at being a clean source for powering the planet, scientists had to figure out how to store it for night-time use.

The new system designed by Meyer and colleagues at UNC and with Greg Parsons' group at North Carolina State University does exactly that. It is known as a dye-sensitized photoelectrosynthesis cell, or DSPEC, and it generates by using the sun's energy to split water into its component parts. After the split, hydrogen is sequestered and stored, while the byproduct, oxygen, is released into the air.

"But splitting water is extremely difficult to do," said Meyer. "You need to take four electrons away from two water molecules, transfer them somewhere else, and make hydrogen, and, once you have done that, keep the hydrogen and oxygen separated. How to design molecules capable of doing that is a really big challenge that we've begun to overcome."

Meyer had been investigating DSPECs for years at the Energy Frontier Research Center at UNC and before. His design has two basic components: a molecule and a nanoparticle. The molecule, called a chromophore-catalyst assembly, absorbs sunlight and then kick starts the catalyst to rip electrons away from water. The nanoparticle, to which thousands of chromophore-catalyst assemblies are tethered, is part of a film of nanoparticles that shuttles the electrons away to make the hydrogen fuel.

However, even with the best of attempts, the system always crashed because either the chromophore-catalyst assembly kept breaking away from the nanoparticles or because the electrons couldn't be shuttled away quickly enough to make hydrogen.

To solve both of these problems, Meyer turned to the Parsons group to use a technique that coated the nanoparticle, atom by atom, with a thin layer of a material called titanium dioxide. By using ultra-thin layers, the researchers found that the nanoparticle could carry away electrons far more rapidly than before, with the freed electrons available to make . They also figured out how to build a protective coating that keeps the chromophore-catalyst assembly tethered firmly to the nanoparticle, ensuring that the assembly stayed on the surface.

With flowing freely through the nanoparticle and the tether stabilized, Meyer's new system can turn the sun's energy into fuel while needing almost no external power to operate and releasing no greenhouse gases. What's more, the infrastructure to install these sunlight-to-fuel converters is in sight based on existing technology. A next target is to use the same approach to reduce carbon dioxide, a greenhouse gas, to a carbon-based fuel such as formate or methanol.

"When you talk about powering a planet with energy stored in batteries, it's just not practical," said Meyer. "It turns out that the most energy dense way to store is in the chemical bonds of molecules. And that's what we did – we found an answer through chemistry."

Now this guy is full of good intentions I am sure. But seriously you have to know just a little something more than this guy to be a legislature...... Don't You?!!!

Apparently not because this fool doesn't have a clue.

State senator uses firearms-related words at random

No one seems to know precisely what a “ghost gun” is. Definitions vary: some define “ghost gun” as a homemade firearm that can evade metal detectors. Others say that the term refers to any unregistered weapon.

What is certain, however, is that California Democrats think these weapons – whatever they are – are a dangerous new threat, and that regulations must be introduced to control them.


Democratic opponents of gun rights have a habit of sprinkling their rhetoric with scary-sounding but essentially meaningless terms like “assault,” “military-style,” and “close combat.” While introducing a new bill intended to regulate ghost guns, California State Senator Kevin de Leon honored this tradition, incorrectly stating the firing rate of a weapon and using words like “magazine” and “clip” seemingly at random.

Meet the Mad Scientists Who Invented Edible Fireworks


People like to call Sam Bompas and Harry Parr the Willy Wonkas of the 21st century. The two Londoners do have some distinctly Wonkalian qualities: the distinct sense of style, the larger-than-life personalities and most notably, a penchant for creating fantastical, logic-defying food experiences. Like Wonka himself, Bompas and Parr once built a 10-foot waterfall flowing with chocolate and have even invented a flavor-changing chewing gum. Even so, the knee-jerk description might be selling the mad food scientists a bit short. As Bompas puts it: “Wonka was a bit of a sadist, and I’d like to think our events are a lot more open and democratic than his approach.”

For the last five years, Bompas and Parr have been operating their eponymously named studio, where they dream up bizarre and magical culinary moments. Most often, the two food nerds work with companies to craft food-related branding experiences.

More than a quarter million people inhaled strawberry smoke.

They’ve designed a series of tasting rooms at Guinness Storehouse in Dublin, worked with Courvoisier to build a four-ton punchbowl that visitors could row across (and drink from) and floated a life-size steamship, the SS Great Britain, in 55,000 liters of lime green jelly.

But this past New Year’s Eve, the studio engineered its biggest event yet: Creating a multi-sensory experience for the midnight fireworks display over the Thames River. “Vodafone came to us and said, ‘What would you like to do? But it has to be a world first,’” Bompas recalls. “And actually, choreographing fireworks to taste and smell and flavor is something that hasn’t been done. So we spent the next six months working out how to do it.”

Fireworks are inherently visual and music has accompanied them for centuries. But the other senses—the senses Bompas & Parr tend to exploit—have mostly been ignored when it comes to pyrotechnics. Bompas & Parr wanted to create the sensation of tasting and smelling fireworks—without actually eating them.

The studio worked with pyrotechnic experts and flavor scientists to build tools that could broadcast the flavors to the massive crowd. More than a quarter million people inhaled strawberry smoke, ate peach-flavored snow, popped orange bubbles and were covered in banana confetti. “It’s the biggest thing we’ve ever done,” Bompas says. “It’s almost like the project we’ve spent our whole lives working on.”

When Bompas & Parr started out, their ambitions were far less ambitious. The initial plan was to create luxury artisanal jelly, which they did for while. Then things started to scale up. They began making intensely crafted jelly molds.

The day I talk to Bompas, he mentions that he just spent the last hour reading about how to sculpt grapes. “It’s quite lovely to be able to do that while at work,” he says. Ancient viticulture is one of Bompas’ most recent fascinations, though when asked what else they’ve been investigating lately, he comes up with a whole list: Cryptolibations (the strange drinks like the one consumed from the holy grail); instant ice, the act of hyper-chilling water so it turns to ice in front of your eyes; Cleopatra’s milk baths; cooking a whole cow at once (“after our culinary hero Alexis Soyer,” Bompas explains); and of course, “Working out the formula to create a universal sense of awe and the best party of all time.”

Clearly, Bompas and Parr do not have typical jobs. Their studio, which employs 10 people, has a kitchen for cooking, a warehouse for experimenting, a library filled with research book and is basically a maze of objects: champagne sabres, a gong to announce meal time, a tiny piece of Princess Diana’s hair used to make occult jam. You know, the usual.

All of this is an attempt to encourage people to reconfigure what they assume food should be about. The experiences Bompas & Parr create challenge people’s sense of taste. Food isn’t just about nutrition anymore. “It’s very rare that I think, have I had my calorific minimums today?” says Bompas. “Food is entertainment now, so let’s make it as entertaining as it can possibly be.”

Coming up with outlandish ideas isn’t the hard part. Making sure those ideas are feasible is what’s really tough. “It’s got to work,” he says. They have a huge library section about cocktails, fruits, meats, world fairs. There’s actually a lot of book work. But it’s not just about tweaking and toying and brainstorming outlandish ideas. “Everyone’s got good ideas,” he says. “We’re just geeky enough to spend six months making it happen and not taking no for an answer.” http://www.wired.com/design/2014/01/two-mad-food-scientists-created-edible-fireworks/#slide-id-398931
