Doggie DNA startup wants to learn about human diseases from dog drool

Posted by in categories: biotech/medical, genetics, health

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.

Meta-Materials Bring Us Another Step Closer to an Invisibility Cloak

Posted by in categories: computing, materials, quantum physics, security, transportation

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.

Why Scientists Want to Study Robot Roaches

Posted by in category: robotics/AI

Roaches are speedy, agile, and nearly indestructible—which is why engineers are so interested in them.

Robots can look like just about anything: people, dinosaurs, quadcopters—you name it. So why would anyone design a robot that looks like one of the grossest and most detested species on the planet?

Well, like cephalopods, roaches’ bodies gives them distinct, if squirm-worthy, advantages—namely, the ability to become nearly two-dimensional to squeeze through cracks and under doors. Cockroaches can flatten themselves to a one-tenth of an inch and can bear loads 900 times heavier than they are (which is why we have to stomp on them extra hard). Perhaps most impressive is their ability to scurry along at top speed when compressed to half their normal height. These attributes make roaches nimble, persistent, and hardy—three supremely useful qualities for a robot, and three reasons scientists have pursued the development of robo-roaches.

Solar micro-grids launched in three remote villages

Posted by in categories: business, solar power, sustainability

The three solar micro-grids, with combined capacity of 35 kilowatts, were installed in the communities of Harkapur in Okhaldhunga district, and Kaduwa and Chyasmitar in Khotang District, as per a statement issued today. They will provide a 24-hour reliable electricity supply to around 540 people in 83 households and 25 local businesses.

“Nearly a quarter of Nepal’s population has no access to electricity and rely heavily instead on kerosene in particular. Since most of them live in remote areas, there is little possibility of connecting to the national power grid in the near future,” said Jiwan Acharya, senior energy specialist at the Asian Development Bank (ADB). “The solar micro-grids that we are piloting here provide a clean, cost-effective, local solution involving private sector that will change the lives of these communities and serve as a model for other far-flung villages.”

Electricity costs for households are forecast at $4 to $6 per month. Currently households relying on kerosene for lighting alone, can pay up to $10 a month. And by using solar power rather than fossil fuels, the project will avoid 41 tonnes of carbon dioxide emissions every year.

Light illuminates the way for bio-bots

Posted by in categories: bioengineering, genetics, health, robotics/AI

CHAMPAIGN, Ill. — A new class of miniature biological robots, or bio-bots, has seen the light — and is following where the light shines.

The bio-bots are powered by muscle cells that have been genetically engineered to respond to light, giving researchers control over the bots’ motion, a key step toward their use in applications for health, sensing and the environment. Led by Rashid Bashir, the University of Illinois head of bioengineering, the researchers published their results in the Proceedings of the National Academy of Sciences.

“Light is a noninvasive way to control these machines,” Bashir said. “It gives us flexibility in the design and the motion. The bottom line of what we are trying to accomplish is the forward design of biological systems, and we think the light control is an important step toward that.”

‘Sweet’ quantum dots light the way for new HIV and Ebola treatment

Posted by in categories: biotech/medical, quantum physics

A research team led by the University of Leeds has observed for the first time how HIV and Ebola viruses attach to cells to spread infection.

The findings, published today in the journal Angewandte Chemie (“Compact, Polyvalent Mannose Quantum Dots as Sensitive, Ratiometric FRET Probes for Multivalent Protein-Ligand Interactions”), offer a new way of treating such viruses: instead of destroying the pathogens, introduce a block on how they interact with cells.

On-the-spot diagnosis of certain cancers with sensitive bionsensor

Posted by in category: biotech/medical

For Gartner and their Emerging Tech graph; may wish to rethink the biosensor being over 10 years away.


MicroRNAs are a newly discovered class of short (about 19 to 24 nuclides in length) fragments of noncoding RNAs that are useful biomarkers for diagnosing various diseases, including cardiac disease and some cancers. Since they are surprisingly well preserved in fluids such as urine and blood, their detection is well suited to a rapid, point-of-care method.

Mi Kyoung Park at the A*STAR Institute of Microelectronics and her co-workers have devised a silicon photonic biosensor that can detect tiny changes in the phase of a light beam caused by hybridization between an immobilized DNA probe and target microRNAs in a sample.
