A robotic microswarm may one day automate the routine of rinsing, brushing, and flossing teeth. A multidisciplinary team developed the technology, which employs a magnetic field to direct the iron oxide nanoparticle-based microrobots into antimicrobial bristle- and floss-shaped arrays. [...]

Researchers have created a model that describes the spread and speed of tornado-like vortex tubes in superfluids. This work expands on a previous study that reported experimental results obtained in superfluid helium-4 within a narrow temperature range. [...]

The expansion of natural gas infrastructure jeopardises energy transition, as natural gas is not a bridge technology towards a 100 per cent renewable energy system as defined by the Paris Climate Agreement. Scientists recommend that politicians and scientists revise the current assumptions about natural gas. [...]

Physicists observed a strange new type of behaviour in a magnetic material when it?s heated up. The magnetic spins ?freeze? into a static pattern when the temperature rises, a phenomenon that normally occurs when the temperature decreases. [...]

Nasa has recently announced funding for a study into the feasibility of sending swarms of miniature swimming robots to explore oceans beneath the icy shells of our Solar System's many 'ocean worlds'. But don?t imagine metal humanoids swimming frog-like underwater. They will probably be simple, triangular wedges. [...]

In just a few hours, scientists can tell which variant has infected a COVID-19 patient -- a critical task that can potentially influence treatment decisions but takes days or weeks at most medical centers. [...]

Schiff base-metal complexes exhibit promising antibacterial and antioxidant properties. However, conventional methods for their preparation can be time-consuming. To reduce the reaction time and improve the quality and quantity of the products, researchers designed a new synthesis technique that uses microwave irradiation and methanol for the preparation of amino acid [...]

Researchers combined laser writing and responsive sensor technologies to fabricate the first highly customizable microscale gas sensing devices. [...]

Weather forecasts, too, are all about data and models these days. But balancing accuracy and viability is a fine act, especially on a global scale and when the stakes are high. [...]

Current AIs are very accurate but inflexible at image recognition. Exactly why this is remains a mystery. Researchers have developed a method called 'Raw Zero-Shot' to assess how neural networks handle elements unknown to them. The results have the potential to help researchers identify the common features that make neural [...]

Explanation methods that help users understand and trust machine-learning models often describe how much certain features used in the model contribute to its prediction. For example, if a model predicts a patient’s risk of developing cardiac disease, a physician might want to know how strongly the patient’s heart rate data [...]

In a step toward robots that can learn on the fly like humans do, a new approach expands training data sets for robots that work with soft objects like ropes and fabrics, or in cluttered environments. [...]

Members of the public sector, private sector, and academia convened for the second AI Policy Forum Symposium last month to explore critical directions and questions posed by artificial intelligence in our economies and societies. The virtual event, hosted by the AI Policy Forum (AIPF) — an undertaking by the MIT Schwarzman [...]

FuseBot is a new robotic system that fuses visual information and radio-frequency signals to efficiently find hidden items buried under a pile of objects, whether or not the targeted item has an RFID tag. [...]

The term “artificial intelligence” really has two meanings. AI refers both to the fundamental scientific quest to build human intelligence into computers and to the work of modeling massive amounts of data. These two endeavors are very different, both in their ambitions and in the amount of progress they have [...]

In the 24 years I’ve worked as a materials scientist, I’ve always been inspired by hierarchical patterns found in nature that repeat all the way down to the molecular level. Such patterns induce remarkable properties—they strengthen our bones without making them heavy, give butterfly wings their color, and make a [...]

Computer scientists develop a method that allows humans to help complex robots build efficient solutions to 'see' their environments and carry out tasks. [...]

Around a year and a half ago, Yann LeCun realized he had it wrong.  LeCun, who is chief scientist at Meta’s AI lab and one of the most influential AI researchers in the world, had been trying to give machines a basic grasp of how the world works—a kind of common [...]

When you picture a hospital radiologist, you might think of a specialist who sits in a dark room and spends hours poring over X-rays to make diagnoses. Contrast that with your dentist, who in addition to interpreting X-rays must also perform surgery, manage staff, communicate with patients, and run their [...]

The inner child in many of us feels an overwhelming sense of joy when stumbling across a pile of the fluorescent, rubbery mixture of water, salt, and flour that put goo on the map: play dough. (Even if this happens rarely in adulthood.) While manipulating play dough is fun and easy [...]

Award-winning AI research? Check. Startup and enterprise experience? Check. Venture capital and Mark Benioff backing? Check. Is that enough for Richard Socher's you.com to take on Google? [...]

Artificial intelligence can understand complex words and concepts by representing the meaning of words in a similar way that correlates with human judgments. [...]

Data science roles are still "sexy" but not immune to the job market turmoil. [...]
