Green hydrogen is often proposed as a climate-friendly alternative to natural gas for energy production. However, the infrastructure for a green hydrogen economy is still in its infancy and may take years to fully materialize, if it happens at all. To bridge this gap and sustain small natural gas power plants in the interim, the German Aerospace Center (DLR) and power-plant service provider Power Service Consulting (PSC) have tested micro-turbines capable of running on hydrogen, natural gas, or a combination of both.

Peter Kutne, head of the Gas Turbines Department at the DLR Institute of Combustion Technology, emphasized the cost and time benefits of retrofitting gas turbines for hydrogen compatibility. Building a new 15-megawatt gas turbine power plant typically requires six years and costs approximately $31 million (€30 million). In contrast, retrofitting an existing plant takes just 1.5 years and costs about a tenth of that amount.

Researchers at Nanyang Technological University in Singapore have unveiled a groundbreaking machine capable of transforming ordinary cockroaches into remotely controlled cyborgs. This innovative device equips each cockroach with portable stimulation and communication electronics in just 68 seconds, a significant improvement over traditional methods that require up to 30 minutes and specialized skills.

The “cyborgized” cockroaches are fitted with an electronic “backpack” that enables remote control through electronic stimulation of their antennae. By stimulating either the left or right antenna, researchers can influence the cockroach’s direction. Unlike earlier techniques that demanded manual precision, the newly developed machine automates the process, paving the way for large-scale production of these enhanced insects. The researchers claim this process is harmless to the cockroaches and can potentially scale to produce hundreds or even thousands of cyborg cockroaches on demand.

Researchers at the Massachusetts Institute of Technology (MIT) have made a significant breakthrough in addressing the global microplastic pollution crisis by developing innovative biodegradable particles that could revolutionize both environmental protection and nutritional supplementation.

Microplastics, tiny plastic particles found ubiquitously across the planet, pose a substantial environmental threat originating from everyday items like tires, clothing, and packaging. Recognizing the urgent need for sustainable solutions, MIT’s chemical engineers have created eco-friendly polymers that naturally decompose into harmless byproducts such as sugars and amino acids.

Researchers from the Karlsruhe Institute of Technology (KIT) and international collaborators have made a groundbreaking advancement in photonic space-time crystals, opening new frontiers for optical technologies with potentially transformative applications in wireless communication, lasers, and information processing.

Photonic space-time crystals represent a remarkable scientific innovation—materials engineered with a unique four-dimensional structure that allows precise manipulation of light’s behavior. Unlike traditional materials, these crystals feature a periodically arranged structure that changes dynamically across three spatial dimensions and time, enabling unprecedented control over light’s spectral properties.
