Researchers take AI to 'kindergarten' in order to learn more complex tasks

Mon, 05/19/2025 - 10:15am
We need to learn our letters before we can learn to read and our numbers before we can learn how to add and subtract. The same principles are true with AI, a team of scientists has shown through laboratory experiments and computational modeling. In their work, researchers found that when recurrent neural networks (RNNs) are first trained on simple cognitive tasks, they are better equipped to handle more difficult and complex ones later on.

AI-powered app enables anemia screening using fingernail selfies

Fri, 05/16/2025 - 10:48am
A groundbreaking new study introduces an AI-powered smartphone app that noninvasively screens for anemia using a photo of a user's fingernail. The study shows the app provides hemoglobin estimates comparable to traditional lab tests, with over 1.4 million tests conducted by 200,000+ users. An estimated 83 million Americans and more than 2 billion people globally are at high risk for anemia -- populations that stand to benefit significantly from this accessible screening tool. The app offers a low-cost, scalable solution that enhances access, especially in underserved and remote communities, while enabling real-time health monitoring and earlier intervention.

Log in to your computer with a secret message encoded in a molecule

Fri, 05/16/2025 - 10:32am
Molecules like DNA are capable of storing large amounts of data without requiring an energy source, but accessing this molecular data is expensive and time consuming. Researchers have now developed an alternative method to encode information in synthetic molecules, which they used to encode and then decode an 11-character password to unlock a computer.

Hexagons for data protection: Proof of location without disclosing personal data

Thu, 05/15/2025 - 10:25am
Location data is considered particularly sensitive -- its misuse can have serious consequences. Researchers have now developed a method that allows individuals to cryptographically prove their location -- without revealing it. The foundation of this method is the so-called zero-knowledge proof with standardized floating-point numbers.

Resistance is futile: Superconducting diodes are the future

Thu, 05/15/2025 - 10:25am
Researchers have discovered the mechanism for supercurrent rectification, in which current flows primarily in one direction in a superconductor. By using a specific iron-based superconductor, they were able to observe this phenomenon over a broad range of magnetic and temperature fields. This understanding paves the way for the design and construction of superconducting diodes and other ultra-low energy electronics.

AI overconfidence mirrors human brain condition

Thu, 05/15/2025 - 10:24am
Agents, chatbots and other tools based on artificial intelligence (AI) are increasingly used in everyday life by many. So-called large language model (LLM)-based agents, such as ChatGPT and Llama, have become impressively fluent in the responses they form, but quite often provide convincing yet incorrect information. Researchers draw parallels between this issue and a human language disorder known as aphasia, where sufferers may speak fluently but make meaningless or hard-to-understand statements. This similarity could point toward better forms of diagnosis for aphasia, and even provide insight to AI engineers seeking to improve LLM-based agents.

Cyberbullying in any form can be traumatizing for kids

Thu, 05/15/2025 - 10:19am
New research shows that cyberbullying should be classified as an adverse childhood experience due to its strong link to trauma. Even subtle forms -- like exclusion from group chats -- can trigger PTSD-level distress. Nearly 90% of teens experienced some form of cyberbullying, accounting for 32% of the variation in trauma symptoms. Indirect harassment was most common, with more than half reporting hurtful comments, rumors or deliberate exclusion. What mattered most was the overall amount of cyberbullying: the more often a student was targeted, the more trauma symptoms they showed.

Light-driven cockroach cyborgs navigate without wires or surgery

Wed, 05/14/2025 - 3:16pm
have created a new type of insect cyborg that can navigate autonomously -- without wires, surgery, or stress-inducing electrical shocks. The system uses a small ultraviolet (UV) light helmet to steer cockroaches by taking advantage of their natural tendency to avoid bright light, especially in the UV range. This method not only preserves the insect's sensory organs but also maintains consistent control over time.
