‘Severe’ geomagnetic storm could blow power grid with satellite, radio blackouts possible during Milton

Posted by in category: climatology

“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.

Breaking up big tech: US wants to separate Android, Play, and Chrome from Google

Posted by in categories: business, law, mobile phones, robotics/AI

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 Single Stage to Orbit Space Plane

Posted by in category: space travel

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 Detect the Quantum “Kick” From a Single Nuclear Decay

Posted by in categories: particle physics, quantum physics

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.

Parkinson’s Discovery Suggests We Already Have an FDA-Approved Treatment

Posted by in categories: biotech/medical, neuroscience

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.

For the first time ever, scientists find that gravity can exist without mass

Posted by in category: cosmology

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…

The First Water Engine

Posted by in categories: sustainability, transportation

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.

Polaris Dawn brings new areas of Research, Medical Care

Posted by in category: biotech/medical

The launch of Polaris Dawn from Kennedy Space Center includes the first civilian commercial spacewalk and other factors that will be firsts for space medicine research. And that’s why Emmanuel Urquieta, an internationally recognized space medicine expert who recently joined UCF’s College of Medicine, is especially excited about this latest mission.

The spacecraft is flying up to 870 miles above Earth—the highest orbit flown in the last half century. And at that altitude, the astronauts will be exposed to higher radiation than most astronauts who stay in low Earth orbit, such as those onboard the International Space Station.

After achieving the high orbit, Polaris Dawn will come down to a lower altitude for the spacewalk. Traditionally, when astronauts exit the spacecraft, there is an airlock that allows the interior of the vehicle to stay pressurized. But during this week’s walk, the entire vehicle will be depressurized so all four astronauts will be exposed to the vacuum of space and must rely on their spacesuits for life support.
