Deepfakes, realistic videos that map the facial expressions of one person onto the face of another, present a formidable political weapon. But this editing does leaves traces. Now a UC Riverside scientists has trained an AI to identify manipulated images at the pixel level with great accuracy.

A group of researchers from Tokyo has demonstrated that their method of machine learning, which involves “transfer learning,” can identify materials with desired properties even from an exceeding small data set.

A new form of gold just two atoms thick is 10 times more efficient than the current gold nanoparticles used as a catalytic substrate. Its high surface-to-volume ratio and flexibility also give it potential for use in bendable screens, electronic inks, and transparent conducting displays.

Pressure regulators rated for use at subzero temperatures must control pressure while reacting to system changes in extreme conditions; failure can lead not only to loss of property and profit, but could threaten operator safety. Where cold temperatures threaten crucial component functionality, meticulous regulator engineering and well thought out, lab-based analysis stand between success and failure.

The Liquid Metal Competence Platform Karlsruhe (LIMCKA) pools the expertise of many institutes and laboratories of the Karlsruhe Institute of Technology (KIT). Their aim is to develop liquid metal technologies that will may be able to accelerate the decoupling of the energy system from carbon that is crucial to averting catastrophic global warming.

A new study reveals that restricting fluid flow observations to before and after comparisons may miss important chemical reactions in flowing fluids. The discovery of microscopic variations that disappear by the end of the observation period has profound implications for industrial, environmental, and biological fields.

Nanostructures made of carbon are extremely versatile: they can desalinate water, store gases, and absorb ions in batteries and supercapacitors. This versatility requires that the distribution, size and shape of the structure’s pores be controlled. Now a team from the HZB Institute for Soft Matter and Functional Materials and the University of Tartu, Estonia has developed a small-angle X-ray scattering technique to gather information on the structure.

In an analytical sampling system, you may need to precondition your sample prior to analysis. You’ll choose your preconditioning module based on the type of sample-transport system and the sample’s current phase—gas or liquid. You may need a field station module installed near the tap, or a fast-loop module installed near the analyzer.

A new optical sensor that combines lasers with a positional sensor could help to more quickly establish whether hospitals and other critical buildings are safe to occupy just after a major earthquake.

Scientists have developed a highly efficient catalyst for generating electrical energy from ethanol. Ethanol, usually made from corn, is easy to make and store. The catalyst makes ethanol a high-density source of off-the-grid power, and may also enable applications such as liquid fuel-cell-powered drones.
