Hydrogen fuel, which produces no heat-trapping air pollution at the point of use, could be the future of clean energy. But first, some of the technology around still has to be improved, and researchers at the University of Alberta believe they have made an important step in that direction, AL Circle reported.

The breakthrough out of the University of Alberta is a new alloy material — dubbed AlCrTiVNi5 — that consists of metals such as aluminum and nickel. The alloy has great potential for coating surfaces that have to endure extremely high temperatures, such as gas turbines, power stations, airplane engines, and hydrogen combustion engines.

Hydrogen combustion engines are different from fuel cells, which also run on hydrogen. They are being used to develop cars that run on clean energy. While fuel cells rely on a chemical process to convert hydrogen into electricity, hydrogen combustion engines burn hydrogen fuel, creating energy via combustion, just like a traditional gas-powered car (but without all the pollution).

“Satellite navigation (GPS) degraded or inoperable for hours,” the SWPC warned.” Radio – HF (high frequency) radio propagation sporadic or blacked out.”

This severe geomagnetic storm is forecast at the same time Hurricane Milton is forecast to strike Florida. While the SWPC did not note if satellite issues could hinder hurricane monitoring, radio blackouts are expected.

The US Department of Justice (DoJ) has submitted a new “Proposed Remedy Framework” to correct Google’s violation of antitrust antitrust laws in the country (h/t Mishaal Rahman). This framework seeks to remedy the harm caused by Google’s search distribution and revenue sharing, generation and display for search results, advertising scale and monetization, and accumulation and use of data.

The most drastic of the proposed solutions includes preventing Google from using its products, such as Chrome, Play, and Android, to advantage Google Search and related products. Other solutions include allowing websites to opt-out of training or appearing in Google-owned AI products, such as in AI Overviews in Google Search.

Google responded to this by asserting that “DOJ’s radical and sweeping proposals risk hurting consumers, businesses, and developers.” While the company intends to respond in detail to DoJ’s final proposals, it says that the DoJ is “already signaling requests that go far beyond the specific legal issues in this case.”

Radian Aerospace has $31 million of funding to develop a single stage to orbit spaceplane. It will use a 3,000 meter long sled to get it up to launch speed. It will deliver 2.27 tons to anywhere on Earth in under one hour. It can land on a regular runway.

The Spaceplane will be about as long as a Boeing 787 and as wide as a 737.

The spaceplane is designed to be fully reusable for up to 100 missions. They plan a 48-hour turnaround time between flights and a 90-minute on-demand launch capability, significantly reducing costs and increasing mission flexibility.

Scientists have devised a method to detect nuclear decay through the subtle movement of microparticles, enhancing our understanding of elusive particles like neutrinos.

This breakthrough paves the way for improved nuclear monitoring tools and could be enhanced by future quantum technologies.

Radioactivity is all around us, even in everyday items. For example, bananas contain trace amounts of radioactive potassium, with approximately 10 nuclei decaying every second in a typical banana. While these tiny amounts of radioactivity are not dangerous, there is growing scientific interest in enhancing the precision of tools for detecting such nuclear decays.

Researchers have discovered how a cell surface protein called Aplp1 can play a role in spreading material responsible for Parkinson’s disease from cell-to-cell in the brain.

Promisingly, an FDA-approved cancer drug that targets another protein called Lag3 – which interacts with Aplp1 – blocks the spread in mice, suggesting a potential therapy may already exist.

In a recent paper, an international team of scientists describes how the two proteins work together to help harmful alpha-synuclein protein clumps get into brain cells.

Dark matter, a mysterious substance thought to make up most of the universe’s mass, has puzzled scientists for nearly a century. First proposed by Dutch astronomer Jan Oort in 1932 to explain the “missing mass” needed for galaxies to stay together, it remains undetected despite decades of research. However, a recent study by Dr. Richard Lieu at The…

Innovations in engine technology are making water a potential fuel source, leveraging hydrogen extracted from H₂O.

Toyota’s latest breakthrough in sustainable mobility — the world’s first water engine. Departing from conventional hydrogen-powered vehicles, this groundbreaking innovation operates at an unprecedented temperature of 2500°C, thanks to its ingenious water-cooled design. But that’s not all — equipped with a special dual injection system, this engine delivers unparalleled efficiency and performance.
