This Week’s Awesome Stories From Around the Web (Through April 14)

ARTIFICIAL INTELLIGENCE AI Learns a New Trick: Measuring Brain Cells Robbie Gonzalez | Wired “For three months, I spent three or four hours a day, five or six days a week, in a small room, peering through a microscope and snapping photos of the brain cells. …This kind of work, which is common in neuroscience research, […]

4 Ways Scientists Hope Nanobots Will Make You Healthier

For most people the phrase “medical robot” probably brings to mind the ground-breaking da Vinci surgical system that has revolutionized minimally-invasive surgery. Either that or the 2-1B droid from Star Wars: the Empire Strikes Back if you’re a sci-fi nerd. But some of the most exciting progress in medical robotics is actually taking place at […]

This One-Cent Lab-on-a-Chip Can Diagnose Cancer and Infections

  Any sufficiently advanced technology is indistinguishable from magic. —Arthur C Clarke Medical diagnostics often feels like magic to me. With just a few drops of blood, doctors can quickly decipher a patient’s general health status—are biomarker levels in range? Are there telltale signs of infection? Are the patient’s cells healthy, or have some quietly […]

Nanobionic Implant Transforms Spinach Into a Bomb Detector

“The trees, the flowers, the plants grow in silence… silence gives us a new perspective.” –Mother Teresa When I think about plants, chatterbox isn’t the first thing that comes to mind. But below the surface of human perception, plants constantly engage in lively and informative conversations with one another. Damaged maple tree saplings, for example, release odorous chemicals into the air to alert their neighbors to amp up defenses against herbivores. Using root systems as… read more

Detecting Cancer Early With Nanosensors and a Urine Test

How might cancer detection, treatment, and prevention change if cancer could be diagnosed by peeing in a cup? According to Dr. Sangeeta Bhatia, about two-thirds of cancer deaths worldwide are probably preventable by techniques we already have in hand. Her laboratory is working to apply those techniques, and at Singularity University’s Her laboratory is working to apply those techniques, and at Singularity University’s Exponential Medicine conference, she shared details of an exciting project: using nanosensors… read more

Mind-Controlled Nanobots Used to Release Chemicals in Living Cockroaches

This is wild: a team of Israeli scientists developed a contraption that uses a person’s brain waves to remotely control DNA-based nanorobots  — while the nanobots were inside a living cockroach. When prompted by a human thought, the clam shell-like robots opened up, revealing a drug-like molecule that tweaked the physiology of the cockroach’s cells. Though “merely a demonstration and proof of concept,” the technology represents a new era of brain-nanomachine interfaces that links a… read more

Singularity University Comes Home: Global Summit Kicks off Today in San Francisco

Singularity University’s inaugural Global Summit is kicking off today in tech capital San Francisco and running through August 30th. The Singularity Hub team will be on the ground, covering some of the best speakers, and bringing you live Facebook interviews to give you a taste of the magic too. SU’s three exponential conferences all have a unique industry focus—finance, medicine, and manufacturing. But the focus of Global Summit is to go broad, showcase trends in… read more

How to Make Molecular Devices? Microscopic DNA Tools May Be Key

DNA codes for life as we know it, but in recent years, scientists have discovered more uses for the molecule. Because DNA is foldable and “sticky,” they’ve begun making microscopic shapes called DNA origami. Over the last decade or so, researchers have improved at this DNA art, and now, Caltech scientists say they used DNA to sketch a glowing masterpiece — a replica of Vincent van Gogh’s famous painting “The Starry Night”— on a canvas the size… read more

Why Your Smartphone’s Battery Sucks Is Finally Revealed

When it comes to modern consumer electronics, we all seem to be obsessed with finding an electrical outlet to charge up. That’s because the lithium-ion batteries that power our smartphones, laptops, and other gadgets have a performance problem: with each charge, they become less efficient, eventually becoming too unstable to function. Now chemists from Texas A&M have uncovered what causes batteries to slowly die: instead of flowing freely, electrons coupled to lithium ions are getting… read more

From Living Computers to Nano-Robots: How We’re Taking DNA Beyond Genetics

DNA is one of the most amazing molecules in nature, providing a way to carry the instructions needed to create almost any life form on… read more
