Scientists has opened a door to faster, cheaper computer chips with the help of ‘DNA origami.’ “We would like to use DNA’s very small size, base-pairing capabilities and ability to self-assemble, and direct it to make nanoscale structures that could be used for electronics,” Adam T. Woolley said.
Stanford’s μTug minibots are on a roll lately.
The latest battery of experiments at Stanford’s Biomimetics and Dextrous Manipulation Lab dealt with harnessing the power of ants in robot form— specifically, researchers hoped to replicate ants’ ability to work together to haul very heavy objects. In the experiments, robots that jump or walk with a quick, jerky force were quickly determined to be inefficient in groups, while the μTugs won out due to the longer duration of pulling force they were able to create with their tiny winches. If you’ve ever played tug of war than this strategy already makes intrinsic sense. Not only could the μTug smimc ants through teamwork, but they anchored themselves to the ground with an adhesive borrowed from gecko toes.
To prove just how powerful the robots are, scientists took a group of six μTugs—which can pull up to 52 pounds each —and had them move a full-sized car with a passenger inside. Did we mention the passenger was the author of the research paper? When those things start self-replicating, he’s going to be the first one they come after.

Could a cheap molecule used to disinfect swimming pools provide the key to creating a new form of DNA nanomaterials?
Cyanuric acid is commonly used to stabilize chlorine in backyard pools; it binds to free chlorine and releases it slowly in the water. But researchers at McGill University have now discovered that this same small, inexpensive molecule can also be used to coax DNA into forming a brand new structure: instead of forming the familiar double helix, DNA’s nucleobases — which normally form rungs in the DNA ladder — associate with cyanuric acid molecules to form a triple helix.
Samsung is bringing second-generation 14nm technology to its midrange smartphone devices this year, along with (we hope) a solid battery life boost. Hopefully manufacturers will use 14nm power savings to offer devices that prioritize battery life over shaving a few millimeters off the frame.
While many tech moguls dream of changing the way we live with new smart devices or social media apps, one Russian internet millionaire is trying to change nothing less than our destiny, by making it possible to upload a human brain to a computer, reports Tristan Quinn.
“Within the next 30 years,” promises Dmitry Itskov, “I am going to make sure that we can all live forever.”
It sounds preposterous, but there is no doubting the seriousness of this softly spoken 35-year-old, who says he left the business world to devote himself to something more useful to humanity. “I’m 100% confident it will happen. Otherwise I wouldn’t have started it,” he says.
Top scientists at Roche Holding AG and AstraZeneca Plc are sizing up potential allies in the fight against cancer: the trillions of bacteria that live in the human body.
“Five years ago, if you had asked me about bacteria in your gut playing an important role in your systemic immune response, I probably would have laughed it off,” Daniel Chen, head of cancer immunotherapy research at Roche’s Genentech division, said in a phone interview. “Most of us immunologists now believe that there really is an important interaction there.”
