Hydrogen fuel is a promising alternative to fossil fuels that only emits water vapor when used and could thus help to lower greenhouse gas emissions on Earth. In the future, it could potentially be used to fuel heavy-duty transport vehicles, such as trucks, trains, and ships, as well as industrial heating and decentralized power generation systems.

Unfortunately, most current methods to produce hydrogen rely on the burning of fossil fuels, which limits its environmental advantages. Given its potential, many energy engineers worldwide have been trying to devise more sustainable strategies to produce hydrogen on a large scale.

One proposed method for the clean production of hydrogen is known as...

Thousands of years from now, what will remain of our digital era? The ever-growing vastness of human knowledge is no longer stored in libraries, but on hard drives that struggle to last decades, let alone millennia.

However, information written into glass by lasers could allow data to be preserved for more than 10,000 years, Microsoft announced in a study on Wednesday.

Since 2019, Microsoft’s Silica project has been trying to encode data on glass plates, in a throwback to the early days of photography, when negatives were also stored on glass.

The system uses silica glass, a common material that is resistant to changes in temperature, moisture and electromagnetic int...

Quantum computers are alternative computing devices that process information, leveraging quantum mechanical effects, such as entanglement between different particles. Entanglement establishes a link between particles that allows them to share states in such a way that measuring one particle instantly affects the others, irrespective of the distance between them.

Quantum computers could, in principle, outperform classical computers in some optimization and computational tasks. However, they are also known to be highly sensitive to environmental disturbances (i.e., noise), which can cause quantum errors and adversely affect computations.

Researchers at the International Quantum Academy, Southern University of Science and Tech...

In recent weeks, a range of large “software-as-a-service” companies, including Salesforce, ServiceNow and Oracle, have seen their share prices tumble.

Even if you’ve never used these companies’ software tools, there’s a good chance your employer has. These tools manage key data about customers, employees, suppliers and products, supporting everything from payroll and purchasing to customer service.

Now new “agentic” artificial intelligence (AI) tools for business are expected to reduce reliance on traditional software for everyday work. These include Anthropic’s Cowork, OpenAI’s Frontier and open-source agent platforms such as OpenClaw.

But just how important are these software-as-a-service companies now? How fast could AI replace them—and are the jobs of people who use the s...
