Key Points

Near-infrared organic light-emitting diodes (OLEDs) that emit about 1,000 nanometers could support biomedical and security technologies. Yet pushing organic light to these longer wavelengths usually causes a steep drop in efficiency. As the energy gap becomes smaller, molecular vibrations more readily turn excited-state energy into heat rather than light.

Central Queensland fossilised fruits discovery changes understanding of plant evolutionary history In short: The first fossil record of the Melastomataceae plant family in Australia or eastern Gondwana has been identified in specimens from central Queensland. A paper on the fossils published this month challenges what scientists previously believed about the plant's origins. It also led to the discovery of a new genus and species.

Study reveals inter-city collaboration on emission reduction boosts sustainability performance

With Hong Kong recently recording record-breaking high temperatures, extreme weather has once again raised public awareness of global warming and emission-reduction measures. A large-scale international study led by The Hong Kong University of Science and Technology (HKUST) has revealed that intercity collaboration on emission reduction can improve overall sustainability performance by more than 10%. This comprehensive analysis covers 4,116 cities and spans 11 years of data, shedding new...

Anthropic's new hardware standard lets AI agents control the physical world

For all the interest in and uptake of agentic AI systems over the past year or so, the world of automated AI has thus far been primarily limited to text, images, code, and other data and actions that take place inside a computer. Anthropic is now aiming to change that somewhat with what it's calling the Model Hardware Standard (MHS), a set of standardized drivers designed to let AI agents easily interface with and control arbitrary devices. For now, the "research preview" of the MHS effort...
