Now may be a pivotal moment to turn toward climate tech investments, according to analysts and leading investors. Although capital in the sector appeared to decline over the past year, new projections and reports reveal significant potential from renewable energy and artificial intelligence to adaptation and resilience technologies. As governments and corporations raise their decarbonization ambitions, climate tech is no longer just a “green idea,” but a strategic and financially viable opportunity.

OpenAI has announced that group chats are rolling out globally to all ChatGPT users on the Free, Go, Plus and Pro plans. The new feature allows you to participate in a shared conversation with friends, family or colleagues, together with ChatGPT, to plan, create and make decisions as a group.

Researchers at Penn State University have developed an unexpectedly simple yet highly advanced approach that could change the way we build smart devices. Instead of expensive laboratory procedures, they used materials similar to children’s “Shrinky Dinks” plastic sheets. Patterns of liquid metal are printed onto these sheets, which shrink when heated and conform to three-dimensional surfaces such as skin, furniture or curved household objects.

As Europe prepares for the transition to 6G networks, researchers, policymakers and citizens are working together to ensure that the next digital revolution is not only faster, but also ethical, sustainable and inclusive. The European project 6G4Society emphasizes that technology should not be viewed merely as a technical leap forward, but as an opportunity to build infrastructure around social values rather than purely market interests.

As of late September 2025, China has reached a total of 4.71 million 5G base stations, according to data from the country’s Ministry of Industry and Information Technology, making it the largest and most extensive 5G network in the world. This impressive growth continued with a net increase of 455,000 new stations compared to the end of the previous year, clearly demonstrating that China’s digital infrastructure expansion is in full swing.

Imagine if your health profile could “read the future” and reveal the risk of developing numerous diseases up to ten years ahead. A new AI system called Delphi-2M has exactly that ambition. Trained on large sets of medical data, it combines clinical history, lifestyle habits and demographic factors to estimate the likelihood of developing more than a thousand different medical conditions. Although it is not yet used in everyday medical practice, this tool opens the door to a revolution in preventive medicine, encouraging earlier interventions and a personalized approach to health.

As the world prepares for the next generation of wireless networks, scientists are increasingly focusing on one key challenge: how to develop 6G technology that will not further harm the environment but instead work in harmony with it. A recent study highlights the potential of green 6G networks, those that rely on renewable energy sources, reduce overall energy consumption and optimize infrastructure in order to mitigate the carbon footprint of telecommunications systems. If 5G networks represent a technical leap forward, 6G green networks could define the very ethics of tomorrow’s connected society.

The development of wireless networks is entering a new era thanks to an innovation that could transform the way we communicate and use technology. A team of scientists has unveiled a chip capable of data transfer speeds unimaginable by today’s standards, paving the way for broader 6G technology development. This breakthrough promises not only faster networks but also the foundation for entirely new applications, from autonomous systems to advanced solutions in healthcare and industry.
