Imagine a world with little or no concrete. Would that even be possible? After all, concrete is everywhere—on our roads, our driveways, in our homes, bridges and buildings. For the past 200 years, it’s been the very foundation of much of our planet.

But the production of cement, which when mixed with water forms the binding agent in concrete, is also one of the biggest contributors to . In fact, about 5 percent of the planet’s greenhouse gas emissions comes from concrete.

An even larger source of is emitted from smokestacks at around the world. Carbon emissions from those plants are the largest source of harmful global greenhouse gas in the world.

Finally there’s a use for dog drool: this spring, a new startup called Embark plans to launch a DNA testing kit for dogs that will tell owners about their canine’s ancestry, and disease risk. That’s not all the founders have in mind though; they may be aiming at human diseases by enlisting our longtime best friends.

Soon, interested pooch lovers will be able to swab their dogs’ slimy cheeks and mail in the sample. By extracting DNA from the swab, Embark’s founder says they’ll be able to trace a dog’s ancestry on a global level. The “Embark Dog DNA Test Kit” will also look for genetic variants that are associated with more than 100 diseases, and inform owners if their dog has a higher than average chance of developing one of them. The kit will also tell owners if their dog is likely to pass disease-associated mutations to a pup — which will likely be valuable information for breeders. Because of this, Embark’s founders say their product will be the most complete kit of its kind. At least, that’s the idea that Embark’s founders will be pitching today at SXSW.

For the company’s founders, the real objective will be the research they’ll be able to conduct with the DNA samples; that became clear when I spoke to two of Embark’s founders on the phone last week. They spent the first 10 minutes of the call talking about the potential of dog genetics to deliver advancements in human health. In fact, they were so enthusiastic about their future research that I had to interrupt them to steer the conversation back to the product we were supposed to discuss.

Next to Quantum and Biocomputing, this is one of my favorites. Cloak material to avoid radar. Unfortunatley, we cannot have access to the material for our autos; but it would be nice to have on my car sometimes when I am running late and having to drive quickly somewhere.


Two separate teams of engineers, both conducting research into meta-materials (composites not found in nature) with the intent of developing a flexible, stretchable and tunable meta-skin, are sharing their discoveries with the world. Although the two developments revolve around the same premise—manipulating electromagnetic waves so that the surface that banquets an object becomes invisible—a few exciting differences between the teams’ approaches sets their research apart.

Engineers at Iowa State University are developing meta-skins which suppresses radar detection, meaning that this version can be seen by the naked eye, but not by cameras. The implications of such a device are many, particularly for covert operations and security, hiding sensitive layouts of electronic components and advancing the development of optical computers.
