News From Space: Ancient Meteorite Crater Found

meteorIn southern Alberta, scientists have found a vast, ancient crater that they claim dates back some 50 to 70 million years. Discovered entirely by accident in near the hamlet of Bow City, some 20 km south-west of Brooks, and 100 km south-east of Calgary. According to assessments of the impact zone, researchers estimate that the space rock would have been the size of an apartment block, and would have left a crater 8 kilometers wide and roughly 2 and half km deep.

All told, this explosive force of this impact would have been 200 times stronger than the most powerful thermonuclear bomb ever built. That’s basically a force of 1000 megatons, a detonation so powerful that anything within 200 km of the impact would have received 1st-degree burns. To put that in perspective, this means that the city of Calgary would have been decimated by the blast, and in Edmonton, some 400 km away, every window would shattered.

Something of that size, throwing that much debris in the air, potentially would have global consequences; there could have been ramifications for decades.

But after eons of erosion, very little of the crater is left. In fact, the discovery happened entirely by accident when a geologist – who was doing some routine mapping of the underground layers a few meters beneath the surface – apparently noticed a circular disturbance that was covered. Schmitt and his lab were called in to inspecting the feature and used seismic data to create a complete image of it. They quickly realized that it was most likely an impact crater, complete with a central peak where the meteorite would have struck.

Alberta_craterThe size of the object can only be estimated, but assuming the meteor was composed mostly of iron, it would have had to have been between 300 and 500 meters in diameter to create a crater of this size. If the meteorite was rock, it would have had to have been a kilometre across. Schmitt said the crater is a rare opportunity to study the floor of an impact crater. His team is now looking for certain types of minerals that form only under certain conditions so as to confirm the crater is from a meteor impact.

But he doesn’t have much doubt. As he put in a recent interview with CBC news:

We’re able to get at the lower parts of (a crater) and see how rocks have been moved around… We’re pretty confident it can only be a meteorite impact. It’s pretty clear.

Once they’ve had a chance to uncover and examine the area in greater detail, a clear picture of the meteorite’s size, composition, and what lasting marks its impact left beyond the crater. This information will only contribute to our understanding of our Solar System, but of the history of our planet as well.

The Future is Here: Smarty Rings

smarty-ringsOkay, its not exactly here yet, but the implications of this idea could be a game changer. It’s known as the Smarty Ring, a crowdfunded idea being advertised on Indiegogo by a group of inventors in Chennai, India. And at its core is a waterproof, stainless steel band that will feature an LED screen and connect to your phone via Bluetooth 4.0 wireless technology.

For some time now, the Chennai-based group has been the source of some controversy, due mainly to the fact that they have no working prototypes of the ring, but also because they have not identified themselves beyond giving their location. They also freely admit that the photos of the Smarty Ring on Indiegogo and on their website are photoshopped.

smarty-rings1Surprisingly, this has not prevented them from being able to mount their campaign to raise money for its development. While the crowdfunding site Kickstarter has rules requiring creators to be clear about the state of a project’s development and show a prototype “demonstrating the product’s current functionality,” Indiegogo has no such rules.

However, this has not stopped their campaign – which officially closed at 11:00 am ET on Dec.11th, 2013 – from raising a total of $299,349 from their original goal of $40,000. Numerous blueprints of what the watch would look like, including detailed images of its electronics, are also available on their campaign page. What’s more, the group is still taking advanced orders and offering discount pricing to anyone who orders one before Dec.30th.

smarty-rings3Also, the group has become much less clandestine since the campaign closed. In response to questions, group spokesperson Karthik said the project was founded by Chennai-based mechatronics engineer Ashok Kumar, and that their team of inventors includes electronic and computer engineers with experience in robotics and nanotechnology.

Ultimately, the goal of the project was to create a high-tech gadget that would also double as “high-end fashion jewelry,” according to an email to CBC News from the team’s marketing director, Karthik, who did not give his last name. The group also claims on their website that the average smartphone user checks their phone every six minutes, and promises to make that unnecessary, saving time and the battery life of the smartphone.

smarty-rings4According to the The Smarty Ring’s site, the features are to include:

  • A clock with stop watch, timer and alarm
  • Notifications of calls, text and email messages, and social networking updates from services such as Facebook, Twitter, and Skype
  • Phone controls that let users accept or reject incoming calls, make outgoing calls to preset numbers, and control music or the phone’s camera
  • A phone tracking feature that beeps when your phone gets more than nine meters away from you
  • The ring charges wirelessly and its creators guarantee 24 hours of battery life

The Smarty Ring team says the retail price for the device will be $275, but backers and people who preorder before Dec.30th will be able to get one at the reduced price of $175. They estimate that delivery will begin sometime in April of 2014. They are also offering cheaper versions that include only the tracking feature or the clock and tracking features.

smarty-rings5Needless to say, if this is a scam, it is clearly a well-thought out and elaborate one. Not only is the idea of a smart ring that can connect wirelessly to other devices and do the job of a smartphone entirely within the bounds of current and developing technology, its a very cool idea. But if it is in fact real, its realization could mean a new wave of innovation and design for the smart devices market.

Currently, designers and developers are working towards the creation of smartwatches, smartphones, tablets and phablets that are not only smaller and much thinner, but also flexible and transparent. An even smaller device, such as a ring or bracelet, that can do the same job but be far more ergonomic, may be just what the market ordered!

And in the meantime, be sure to enjoy this promotional video from the Smarty Ring website. And be sure to check out their website and determine for yourself if they are liars, inventors, or just plain dreamers:

Ending World Hunger: Insect-Based “Power Flour”

insect_flourIt has long been understood that if we, as a species, are going to deal with overpopulation and hunger, we need take a serious look at our current methods of food production. Not only are a good many of our practices unsustainable – monoculture, ranching, and overuse of chemical fertilizers being foremost amongst them – it is fast becoming clear that alternatives exist that are more environmentally friendly and more nutritious.

However, embracing a lot of these alternatives means rethinking our attitudes to what constitutes food. All told, there are millions of available sources of protein and carbohydrates that aren’t being considered simply because they seem unappetizing or unconventional. Luckily, researchers are working hard to find ways to tackle this problem and utilize these new sources of nutrition.

HULT-PRIZE-large570One such group is a team of McGill University MBA students who started the Aspire Food Group, an organization that will produce nutritious insect-based food products that will be accessible year-round to some of the world’s poorest city dwellers. Recently, this group won the $1 million Hult Prize for the development of an insect-infused flour that offers all the benefits of red meat – high protein and iron – but at a fraction of the cost.

The team – which consists of Mohammed Ashour, Shobhita Soor, Jesse Pearlstein, Zev Thompson and Gabe Mott – were presented with the social entrepreneurship award and $1 million in seed capital back in late September. The presentation was made by former U.S. president Bill Clinton in New York City at the Clinton Global Initiative’s annual meeting.

world_hungerThe Hult Prize Foundation runs an annual contest open to teams of four or five students from colleges and universities from around the world. Their task is to develop ideas for social enterprises – organizations that use market-based strategies to tackle social or environmental problems. This year’s challenge, selected by Clinton, was to tackle world hunger.

Over 10,000 students entered, and the McGill team was one of six which reached the final stage, where they pitched their idea Monday to judges that included Clinton, Nobel Peace Prize laureate Muhammad Yunus and Erathrin Cousin, CEO of the World Food Program. The $1 million was provided by the family of the Swedish billionaire Bertil Hult, who made his fortune with the venerable EF Education First company.

insect_flour1Mohammed Ashour explained the process behind the insect flour in an interview to CBC News:

We are farming insects and we’re grinding them into a fine powder and then we’re mixing it with locally appropriate flour to create what we call power flour. It is essentially flour that is fortified with protein and iron obtained from locally appropriate insects.

What is especially noteworthy about the product, aside from its sustainability, is the fact that it delivers plenty of protein and iron in an inexpensive package. These nutrients, the team noted, are in short supply in the diets of many people in developing nations, but can be found in high amounts in insects. For example, they note, crickets have a higher protein content per weight than beef.

???????????????????????????????And while the idea of eating insects might seem unappealing to many people living in the developed world, Soor pointed out that people in many of the countries they are targeting already eat insects. In addition, the type of insect used to produce the flour for a local market would be chosen based on local culinary preferences. As she put it:

There really isn’t a ‘yuck’ factor. For example, in Mexico, we’d go with the grasshopper. In Ghana, we’d go with the palm weevil.

The insects would also be mixed with the most common type of local flour, whether it be made from corn, cassava, wheat or something else. Thus, the product would not only provide nutrition, but would be locally sourced to ensure that it is accessible and beneficial to the local market.

Developed-and-developing-countriesIn addition, the team has already held taste tests in some markets. In one test, they offered people tortillas made from regular corn flour, corn flour containing 10 per cent cricket flour and corn flour containing 30 per cent cricket flour. As Ashour indicated, the reviews were met with approval:

Amazingly enough, we got raving reviews for the latter two… so it turns out that people either find it to be tasting neutral or even better than products that are made with traditional corn flour.

The team hopes to use the prize money to help them expand the reach of their organization to the over 20 million people living in urban slums around the world by 2018. And I can easily foresee how flours like this one could become a viable item when teamed up with 3D food printers, tailoring edible products that meet our nutritional needs without putting undue strain on the local environment.
