Gravitational waves rippling from black hole merger could help test general relativity

Posted by in categories: cosmology, physics

Scientists have discovered gravitational waves stemming from a black hole merger event that suggest the resultant black hole settled into a stable, spherical shape. These waves also reveal the combo black hole may be much larger than previously thought.

When initially detected on May 21, 2019, the gravitational wave event known as GW190521 was believed to have come from a merger between two black holes, one with a mass equivalent to just over 85 suns and the other with a mass equivalent to about 66 suns. Scientists believed the merger therefore created an approximately 142 solar mass daughter black hole.

Yet, newly studied spacetime vibrations from the merger-created black hole, rippling outward as the void resolved into a proper spherical shape, seem to suggest it’s more massive than initially predicted. Rather than possess 142 solar masses, calculations say it should have a mass equal to around 250 times that of the sun.

Revolution in Skies: Reliable Robotics Achieves Unmanned Flight, Paving Way for Future of Aviation

Posted by in categories: robotics/AI, transportation

In a significant stride forward for aviation, Reliable Robotics, a trailblazer in aircraft automation systems, has successfully operated a Cessna 208B Caravan with no one on board. The aircraft, while not as large as a 737–100, is still a considerable size, marking a noteworthy milestone in the field of aviation automation.

The flight was remotely controlled from Reliable’s control center, located 50 miles away. This system is not just about remote control, but full automation of the aircraft, including taxi, takeoff, and landing. The technology is designed to prevent controlled flight into terrain and loss of control in flight, two major causes of fatal aviation accidents.

A Chatbot from the 1960s has thoroughly beaten OpenAI’s GPT-3.5 in a Turing test, because people thought it was just ‘too bad’ to be an actual AI

It also turns out that we’re not especially good at figuring out if real people are humans, either.

Historic magnetic storms help scientists learn what to expect when one hits

Posted by in categories: particle physics, space

As someone who never lived in the extreme northern latitudes of Earth, I always found it exciting when I heard auroras might be visible farther south. I would always crane my eyes skyward, hoping I could see those ghostly dancing lights, almost trying to wish them into existence. Alas, I was never that lucky. Though as we approach solar maximum in 2025, we ought not to only get excited about seeing auroras, but perhaps also ask: What could a powerful geomagnetic storm do to our technological infrastructure?

Geomagnetic storms can be triggered by either coronal mass ejections, giant bubbles of plasma erupting from the surface of the sun, or very powerful solar flares. It’s because these events can accelerate particles to extremely fast speeds. And when some of those particles hit the Earth’s magnetic field, this generates what we see as brilliant auroras — however, those particles can also damage satellite equipment and even harm astronauts in orbit.

A truly gigantic magnetic storm has not affected the Earth in well over one hundred years — and since then, technology has changed quite significantly. Satellite communications, air travel and the power grid have been brought into existence, and they all can be impacted by these events. Yet, scientists aren’t quite sure what, exactly, would happen to the integral technological components of society if a major solar storm shrouded Earth with charged particle showers.

Unprecedented Gigantic ‘Hole’ in the Sun Spews Superfast Solar Wind Towards Earth

Posted by in category: futurism


• A massive coronal hole, wider than 60 Earths, has opened up on the sun’s surface, releasing unusually fast solar wind towards Earth. This phenomenon is unprecedented at this stage of the solar cycle.

• The hole, which took shape near the sun’s equator on Dec. 2, reached its maximum width of around 497,000 miles within 24 hours. Since Dec. 4, it has been pointing directly at Earth.

Impact of New Respiratory Illness Outbreak in China on the US and Other Regions

Posted by in category: biotech/medical


• A sudden rise in respiratory ailments in China, particularly among children, has raised global concern. The Chinese Center for Disease Control and Prevention reported over 3,500 cases of respiratory infection, with Chinese media attributing the outbreak to mycoplasma pneumonia.

• The World Health Organization has been monitoring the situation since mid-October 2023 and has requested more information from China. As of November 24, no unusual or novel pathogens have been reported in the clusters of pneumonia cases.

Oldest mosquito fossil comes with a bloodsucking surprise

Posted by in category: biotech/medical

WASHINGTON, Dec 5 (Reuters) — Hundreds of thousands of people worldwide are killed annually by malaria and other diseases spread through the bite of mosquitoes, insects that date back to the age of dinosaurs. All of these bites are inflicted by females, which possess specialized mouth anatomy that their male counterparts lack.

But it has not always been that way. Researchers said they have discovered the oldest-known fossils of mosquitoes — two males entombed in pieces of amber dating to 130 million years ago during the Cretaceous Period and found near the town of Hammana in Lebanon. To their surprise, the male mosquitoes possessed elongated piercing-sucking mouthparts seen now only in females.

“Clearly they were hematophagous,” meaning blood-eaters, said paleontologist Dany Azar of the Chinese Academy of Sciences’ Nanjing Institute of Geology and Paleontology and Lebanese University, lead author of the study published this week in the journal Current Biology. “So this discovery is a major one in the evolutionary history of mosquitoes.”

12-billion-year-old Body of Water Discovered Floating in Space

Posted by in category: space

Two teams of astronomers led by scientists at Caltech, have discovered the largest reservoir of water ever detected in the universe. And it’s 30 billion trillion miles away.

Yep, you read that correctly. The largest reservoir has been found in the cosmos, more specifically in a quasar, which is one of the brightest and most violent objects in the cosmos.

The mass of water vapour is at least 140 trillion times more than all of the water in the world’s oceans combined.
