App enables smallholder farmers to be community influencers and citizen scientists

The GeoFarmer app enables smallholder farmers to collect and share vital information on climate-related agricultural interventions. Farmers produced tens of thousands of data points despite limited internet connectivity, demonstrating the app's potential to increase communication and empower farmers.

Enhancing power supply resilience to first responders

A new research project aims to develop an automated resilience management system (ARMS) to improve the city's power grid in case of a power outage. The system will utilize distributed solar photovoltaics, distributed energy resources, fault detection sensors, and distribution monitoring equipment to enhance critical infrastructure and ...

Intelligent metamaterials behave like electrostatic chameleons

A new class of intelligent metamaterials, called metashells, has been developed to respond to nearby objects. These materials can change their physical characteristics, such as permittivity, in accordance with the electromagnetic properties of the material they contain, enabling adaptive behavior.

Which came first, the lizard or the egg?

In a groundbreaking study, scientists at the University of Sydney observed a normally live-bearing Australian lizard lay eggs and then weeks later, give birth to a live baby from the same pregnancy. This unusual reproductive trait is known as bimodality, where some individuals lay eggs while others give birth to live young.

Beware a glacier's tongue

Researchers at Hokkaido University used sonar to map the underwater shape of Grey Glacier, revealing a submerged terrace extending 100 meters beyond its visible portion. This unique structure is different from ocean-bound glaciers and can lead to huge chunks of ice falling off, posing a safety risk to humans in the vicinity.
