An alternative satellite messaging service was spotted in the latest beta version of Android 14, and it may be included in Android 15.

According to an Android Authority report, the Android beta now shows a new “Satellite Messaging” page that states users can “send and receive text messages by satellite as part of an eligible account.” Next is a button that users can tap once it arrives to add the feature to their mobile plan.

In terms of functionality, users can take advantage of it when they don’t have a cellular or Wi-Fi connection. In addition to emergency services, users can contact anyone they know. It is claimed that the antennas would support 2 to 4MB of data transmission per cell area.

Electromagnetic waves in the terahertz frequency range offer many advantages for communications and advanced applications in scanning and imaging, but realizing their potential poses challenges. Researchers at Tohoku University have addressed one of the key challenges by developing a new type of tunable filter for signals in the terahertz wave band. They published their work in the journal Optics Letters.

Bitcoin has crushed its highest price ever, blasting past $72,000 for the first time in its history today.

The news comes after UK regulators announced they wouldn’t stand in the way of the creation of crypto-backed, exchange-traded notes (cETNs), CNBC reports. ETNs are a type of unsecured debt securities that trade on major exchanges, kind of like a stock.

The value of the mainstream cryptocurrency has risen considerably since the beginning of the year, spurred on by its growing acceptance by regulators around the globe and the fading shadow of the FTX collapse.

Due to the world’s largest gravity hole, the sea level in a large part of the Indian Ocean is up to 106 m (348 ft) lower than the rest of the world. We have just understood what causes this huge ‘black hole.’

If you look at a map of Earth’s gravity, you will see a huge blue spot south of India, indicating a region where gravity is weaker than average. This spot is called the Indian Ocean Geoid Low (IOGL), and it is the largest gravity anomaly on our planet.

A gravity anomaly is a difference between the actual gravity measured at a location and the theoretical gravity expected for a perfectly smooth and spherical Earth. But Earth’s gravity isn’t perfectly uniform and variations in mass distribution beneath the surface cause fluctuations in gravitational pull.

Pixart-σ weak-to-strong training of diffusion transformer for 4K text-to-image generation.

PixArt-Σ

Weak-to-strong training of diffusion transformer for 4K text-to-image generation.

In this paper, we introduce PixArt-Sigma, a Diffusion Transformer model~(DiT) capable of directly generating images at 4K resolution.

The Short-Baseline Near Detector collaboration is preparing for an exciting year at the U.S. Department of Energy’s Fermi National Accelerator Laboratory. After nearly a decade of planning, prototyping and construction, the team is in the final stretch of commissioning of their detector.

In January, engineers began introducing gaseous argon into SBND to push air out of the cryostat. Now that the detector is mostly free of impurities, the team has begun filling it with liquid argon.

“We’re all excited to get to this point. It’s one of the last steps before we see our first particle tracks,” said Roberto Acciarri, the detector assembly and installation co-coordinator for SBND.
