Submission + - Humans Made a Space Barrier Around Earth that Is Saving Us...Whoops! (popularmechanics.com)

Submitted by joshuark
joshuark writes: The mysterious zone of anthropogenic space weather is caused by specific kinds of radio waves that we’ve been blasting into the atmosphere for decades, but experts say the expanding band actually helps protect humankind from dangerous space radiation. NASA first observed this belt in 2012. The agency sends probes to explore different parts of our solar system, including the Van Allen Belts: a huge, torus-shaped area of radiation that surrounds Earth. The donut shape follows the equator, leaving the North and South Poles free.

The Van Allen Belts are related to and affected by the magnetosphere induced by the nonstop bombardment of the sun’s radiation. They affect benign-seeming magnetic effects like the Northern Lights, as well as more destructive ones like magnetic storms. People planning spaceflight through areas affected by the Van Allen Belts, for example, must develop radiation shielding to protect crew as well as equipment—and most spacecraft launch from as near to the equator as possible, right in the Van Allen zone.
So, what’s our new protective barrier? The same probes that launched in 2012 to help us understand the Belts better in the first place detected this phenomenon, and in 2017, the probes gave us the first evidence of the radio-wave barrier emanating from Earth.

Why is this? Well, the very low frequency (VLF) waves are exactly right to cancel out and repel the radiative advances of the Van Allen Belts as a matter of total coincidence. In fact, NASA initially considered this a true coincidence, saying that a radio wave area happened to match exactly with the edge of the Van Allen Belts.

Isn’t it interesting that VLF blankets the Earth without interfering with literally any other radio signal, for example, or the many other kinds of waves that flow around us all the time, but makes it into space far enough to push away harmful radiation?
This means that, for example, space programs could develop VLF technology to punch holes for spacecraft to travel through. As always, truth is stranger than fiction.

Maybe we won't have to worry about the Van Allen belt combusting and cooking all life on Earth as was suggested in the movie "Voyage to the Bottom of the Sea"...phew!

Submission + - James Webb Space Telescope confirms 1st 'runaway' supermassive black hole (space.com) 1

Submitted by schwit1
schwit1 writes: Astronomers have made a truly mind-boggling discovery using the James Webb Space Telescope (JWST): a runaway black hole 10 million times larger than the sun, rocketing through space at a staggering 2.2 million miles per hour (1,000 kilometers per second).

That not only makes this the first confirmed runaway supermassive black hole, but this object is also one of the fastest-moving bodies ever detected, rocketing through its home, a pair of galaxies named the "Cosmic Owl," at 3,000 times the speed of sound at sea level here on Earth. If that isn't astounding enough, the black hole is pushing forward a literal galaxy-sized "bow-shock" of matter in front of it, while simultaneously dragging a 200,000 light-year-long tail behind it, within which gas is accumulating and triggering star formation.

Submission + - Swearing Actually Seems to Make Humans Physically Stronger (sciencealert.com)

Submitted by alternative_right
alternative_right writes: Eighty-eight participants, aged 18 to 65, all in good enough shape to exert themselves physically, were recruited at a university campus to participate in the first experiment.

They each selected a pair of words based on the following prompts: a swear word you might utter after bumping your head, and a neutral word you might use to describe a table.

Then, they undertook a chair push-up, which involves sitting in a chair and, holding each side of the seat, using your arms to lift your entire body weight (bottom off the chair, feet off the floor). ...Both experiments suggested that swearing offers an advantage in physical performance, with participants achieving longer chair push-up hold times as they repeated their foul-mouthed mantras.

Submission + - Man tailgates his way onto a flight at London Heathrow (telegraph.co.uk)

Submitted by Bruce66423
Bruce66423 writes: 'A man boarded a flight at Heathrow without a ticket, boarding pass or passport.

'The unnamed individual walked onto the 7.20am British Airways (BA) flight to Oslo, Norway, on Saturday after tailgating other passengers through security and evading checks at the departure gate.

'An aviation expert described the incident as a “significant lapse in security”, as a witness reported that cabin crew only detected the interloper because the flight was full and he kept sitting in passengers’ assigned seats.

'Police arrested the unnamed man, airport sources said, adding that he had passed through “full security screening” before reaching the gate.'

Given that he did go through the security check, this is merely embarrassing.

Submission + - Oh look, yet another Starship clone has popped up in China. (arstechnica.com) 1

Submitted by schwit1
schwit1 writes: The trend began with the Chinese government. In November 2024 the government announced a significant shift in the design of its super-heavy lift rocket, the Long March 9. Instead of the previous design, a fully expendable rocket with three stages and solid rocket boosters strapped to the sides, the country’s state-owned rocket maker revealed a vehicle that mimicked SpaceX’s fully reusable Starship.

Around the same time, a Chinese launch firm named Cosmoleap announced plans to develop a fully reusable “Leap” rocket within the next few years. An animated video that accompanied the funding announcement indicated that the company seeks to emulate the tower catch-with-chopsticks methodology that SpaceX has successfully employed.

But wait, there’s more. In June a company called Astronstone said it too was developing a stainless steel, methane-fueled rocket that would also use a chopstick-style system for first stage recovery. Astronstone didn’t even pretend to not copy SpaceX, saying it was “fully aligning its technical approach with Elon Musk’s SpaceX.”

And then, on Friday, the state-aligned China.com reported that a company called “Beijing Leading Rocket Technology” took things a step further. It has named its vehicle “Starship-1,” adding that the new rocket will have enhancements from AI and is billed as a “fully reusable AI rocket.”

Submission + - Researchers Build Quantum Antenna to Precisely Measure Terahertz Signals (scitechdaily.com)

Submitted by fahrbot-bot
fahrbot-bot writes: SciTechDaily is reporting that a research team has created a quantum antenna capable of precisely measuring terahertz frequency combs for the first time.

A research team from the Faculty of Physics and the Centre for Quantum Optical Technologies at the Centre of New Technologies, University of Warsaw has introduced a new approach for detecting extremely weak terahertz signals by using a “quantum antenna.” Their method relies on a specialized system that employs Rydberg atoms for radio wave detection, allowing them not only to capture these signals but also to accurately calibrate a frequency comb in the terahertz range.

This part of the electromagnetic spectrum was considered largely unexplored until recently, and the breakthrough, reported in Optica, offers a pathway toward highly sensitive spectroscopy and a new class of quantum sensors that can function at room temperature.

Terahertz (THz) radiation occupies a unique position within the electromagnetic spectrum, sitting between microwaves (such as those used in Wi-Fi) and infrared light at the intersection of electronics and optics. It promises a wide range of applications, including scanning packages without harmful X-rays, enabling ultra-fast 6G communication, and advancing spectroscopy and organic compound imaging.

Submission + - Microsoft Will Finally Kill Obsolete Cipher That Has Wrecked Decades of Havoc (arstechnica.com)

Submitted by Anonymous Coward
An anonymous reader writes: Microsoft is killing off an obsolete and vulnerable encryption cipher that Windows has supported by default for 26 years following more than a decade of devastating hacks that exploited it and recently faced blistering criticism from a prominent US senator. When the software maker rolled out Active Directory in 2000, it made RC4 a sole means of securing the Windows component, which administrators use to configure and provision fellow administrator and user accounts inside large organizations. RC4, short for Rivist Cipher 4, is a nod to mathematician and cryptographer Ron Rivest of RSA Security, who developed the stream cipher in 1987. Within days of the trade-secret-protected algorithm being leaked in 1994, a researcher demonstrated a cryptographic attack that significantly weakened the security it had been believed to provide. Despite the known susceptibility, RC4 remained a staple in encryption protocols, including SSL and its successor TLS, until about a decade ago. [...]

Last week, Microsoft said it was finally deprecating RC4 and cited its susceptibility to Kerberoasting, the form of attack, known since 2014, that was the root cause of the initial intrusion into Ascension’s network. “By mid-2026, we will be updating domain controller defaults for the Kerberos Key Distribution Center (KDC) on Windows Server 2008 and later to only allow AES-SHA1 encryption,” Matthew Palko, a Microsoft principal program manager, wrote. “RC4 will be disabled by default and only used if a domain administrator explicitly configures an account or the KDC to use it.” [...] Following next year’s change, RC4 authentication will no longer function unless administrators perform the extra work to allow it. In the meantime, Palko said, it’s crucial that admins identify any systems inside their networks that rely on the cipher. Despite the known vulnerabilities, RC4 remains the sole means of some third-party legacy systems for authenticating to Windows networks. These systems can often go overlooked in networks even though they are required for crucial functions.

To streamline the identification of such systems, Microsoft is making several tools available. One is an update to KDC logs that will track both requests and responses that systems make using RC4 when performing requests through Kerberos. Kerberos is an industry-wide authentication protocol for verifying the identities of users and services over a non-secure network. It’s the sole means for mutual authentication to Active Directory, which hackers attacking Windows networks widely consider a Holy Grail because of the control they gain once it has been compromised. Microsoft is also introducing new PowerShell scripts to sift through security event logs to more easily pinpoint problematic RC4 usage. Microsoft said it has steadily worked over the past decade to deprecate RC4, but that the task wasn’t easy.

Submission + - Young Journalists Drone, Expose Russian Ships Off Dutch-German Coasts (digitaldigging.org)

Submitted by schwit1
schwit1 writes: Seven German journalism students, as a continuation of their OSINT course project, tracked the movements of ships with Russian crews off the coasts of the Netherlands and Germany and linked them to swarms of drones appearing over European military airfields and other strategic sites.

The guys not only analyzed thousands of data points, but also used leaked documents, established connections with sources in European agencies, and drove 2,500 km across three countries chasing one of the ships – even launching their own drone to fly over it.

At the end of the article, there’s precise data on the vessels, so you can follow them yourself.

You have completely misunderstood the political and economical system in the US. There is no such thing as "capitalism", see here https://ancillary-proxy.atarimworker.io?url=https%3A%2F%2Fdagens-fel.livejournal...

Stop using the word "capitalism" (unless you are analysing Marx' ideas).

Submission + - Japan renders current conventional submarines obsolete (x.com)

Submitted by schwit1
schwit1 writes: With the Taigei class and its lithium-ion batteries, Tokyo already set a new benchmark: up to three weeks submerged without ever raising a snorkel. That, however, was merely the opening act.

Today, Toyota and Panasonic are leading the global race in solid-state batteries, with prototypes arriving in 2027–2028, mass production after 2030, and Japan’s next submarine class will be the first to use them, either in pure battery form or as a hybrid with a small reactor for onboard recharging. This hybrid would be similar to what the Chinese are developing.

The leap is staggering. A 4,000 ton conventional submarine will patrol for 40 to 60 days without surfacing, sprint well above 20 knots for hours on end, and do it all more quietly than many nuclear subs, thanks to being significantly lighter and running solely on battery power.

Solid-state cells weigh roughly one-third as much, generate 40% less heat, and eliminate half the cooling systems. The result is a faster, stealthier hull that can travel thousands of kilometers without ever breaking the surface.

Those hundreds of saved tons translate directly into more powerful electric motors, extra torpedoes and missiles, cutting-edge sensors, or greater crew comfort. The same hull now carries twice the energy or twice the weapons.

It appears there are also plans to equip the system with Mitsubishi Heavy Industries’ micro nuclear reactor. Its design has no moving parts, which gives it excellent quietness. It’s essentially like a battery that can run for 20 years.
