Want to spot a deepfake? Look for the stars in their eyes

Wed, 07/17/2024 - 9:11am
In an era when the creation of artificial intelligence (AI) images is at the fingertips of the masses, the ability to detect fake pictures -- particularly deepfakes of people -- is becoming increasingly important. So what if you could tell just by looking into someone's eyes? That's the compelling finding of new research which suggests that AI-generated fakes can be spotted by analyzing human eyes in the same way that astronomers study pictures of galaxies.

Completely stretchy lithium-ion battery for flexible electronics

Wed, 07/17/2024 - 9:10am
When you think of a battery, you probably don't think stretchy. But batteries will need this shape-shifting quality to be incorporated into flexible electronics, which are gaining traction for wearable health monitors. Now, researchers report a lithium-ion battery with entirely stretchable components, including an electrolyte layer that can expand by 5000%, and it retains its charge storage capacity after nearly 70 charge/discharge cycles.

Paving the way to extremely fast, compact computer memory

Wed, 07/17/2024 - 9:09am
Researchers have demonstrated that the layered multiferroic material nickel iodide (NiI2) may be the best candidate yet for devices such as magnetic computer memory that are extremely fast and compact. Specifically, they found that NiI2 has greater magnetoelectric coupling than any known material of its kind.

Enzyme-powered 'snot bots' help deliver drugs in sticky situations

Wed, 07/17/2024 - 9:00am
Snot might not be the first place you'd expect nanobots to be swimming around. But this slimy secretion exists in more places than just your nose and piles of dirty tissues -- it also lines and helps protect the lungs, stomach, intestines and eyes. And now, researchers have demonstrated in mice that their tiny, enzyme-powered 'snot bots' can push through the defensive, sticky layer and potentially deliver drugs more efficiently.

Scientists use machine learning to predict diversity of tree species in forests

Tue, 07/16/2024 - 12:12pm
Researchers used machine learning to generate highly detailed maps of over 100 million individual trees from 24 sites across the U.S. These maps provide information about individual tree species and conditions, which can greatly aid conservation efforts and other ecological projects.

How to assess a general-purpose AI model's reliability before it's deployed

Tue, 07/16/2024 - 12:12pm
A new technique estimates the reliability of a self-supervised foundation model, like those that power ChatGPT, without the need to know what task that model will be deployed on later.

Metamaterials for the data highway

Tue, 07/16/2024 - 9:27am
Researchers have been the first to demonstrate that not just individual bits, but entire bit sequences can be stored in cylindrical domains: tiny, cylindrical areas measuring just around 100 nanometers. As the team reports, these findings could pave the way for novel types of data storage and sensors, including even magnetic variants of neural networks.
