This feels inevitable.

Like it or not, humans are becoming as gods. Where will this trend lead?How about the ability to bring back to life people who died years, decades, or centur…

6D Heterotic Little String Theories(LSTs) are a subsector of every 6D SUGRA (with at least one tensor multiplet), after decoupling gravity. As such, while possessing usual QFT-like properties such as global symmetries, they also possess gravity-like properties such as T-duality, which makes them an interesting intermediate. Recently, a fruitful line of research has been to chart the landscape of T-dual LSTs, and establish certain invariants across this T-duality, which includes the 5D Coulomb branch dimension, and the 2-Group structure constants (mixed anomalies). In this talk, we will argue that the rank of the flavor algebra is another invariant across this duality. This involves using 6D anomaly cancellation conditions and carefully taking into account potential ABJ anomalies. We will then discuss some interesting novel LSTs with non-trivial flavor holonomies, focusing on their T-duality structure. Based on arXiv:2311.02168.

Jan Bartek — AncientPages.com — Some already call it Australia’s lost Atlantis, but it is not quite the mythical underwater city Plato mentions. A large underwater site that was home to hundreds of thousands of people has been identified and mapped by scientists. Rising seas submerged the land northwest of Australia at the end of the last glacial period.

Using newly available high-resolution sonar data, the research team reconstructed the topography of the 400,000 square kilometers of land that is now covered by the Indian Ocean, known as the Northwest Shelf.

The engines driving the growth of the world’s highest mountains into the sky run deep beneath the planet’s skin. Geologists have some idea of the mechanisms at work, but evidence has so far left plenty of room for debate over the details.

Combined with a fresh look at previous research, a recent analysis of new seismic data collected from across southern Tibet has delivered a surprising depiction of the titanic forces operating below the Himalayas.

Presenting at the American Geophysical Union conference in San Francisco last December, researchers from institutions in the US and China described a disintegration of the Indian continental plate as it grinds along the basement of the Eurasian tectonic plate that sits atop it.

The Texas grid is not the same as it was when a cascade of failures struck in February 2021.

On Jan. 2, a 27-foot sailboat sank off the southern coast of Alameda in stormy weather. Rescue crews saved the man on board, but the ship landed beside a long rock wall jutting from the island.
