EMPs aren’t science fiction. Real militaries are experimenting on real EMP generators, and as Starfish Prime showed us, space nukes can send powerful EMPs to the surface. So what exactly is an EMP, and how dangerous are they?

Supercomputers Crack the Code of Super-Diamond Synthesis

Researchers are on a quest to synthesize BC8, a carbon structure predicted to be tougher than diamond, using insights from advanced simulations and experimental efforts. This material, theoretically prevalent in the extreme pressures of exoplanets, remains a scientific mystery with promising applications in materials science.

Diamond is the strongest material known. However, another form of carbon has been predicted to be even tougher than diamond. The challenge is how to create it on Earth.

The eight-atom body-centered cubic (BC8) crystal is a distinct carbon phase: not diamond, but very similar. BC8 is predicted to be a stronger material, exhibiting a 30% greater resistance to compression than diamond. It is believed to be found in the center of carbon-rich exoplanets. If BC8 could be recovered under ambient conditions, it could be classified as a super-diamond.

Radiation From Massive Stars — 100,000 Times More Luminous Than the Sun — Shapes Planetary Systems

An international team used the James Webb Space Telescope to study a protoplanetary disc in the Orion Nebula, revealing how massive stars significantly influence the formation of planetary systems. They discovered that intense ultraviolet radiation from these stars can prevent the formation of Jupiter-like planets in systems like d203-506, providing new insights into the complexities of how planetary systems develop.

How do planetary systems such as the Solar System form? To find out, CNRS scientists taking part in an international research team[1] studied a stellar nursery, the Orion Nebula, using the James Webb Space Telescope.[2] By observing a protoplanetary disc named d203-506, they have discovered the key role played by massive stars in the formation of such nascent planetary systems.[3].

KaistAI/Semiparametric_Token-Sequence_Co-Supervision

“Semiparametric Token-Sequence Co-Supervision”

We introduce semiparametric token-sequence co-supervision, which trains LM by simultaneously leveraging supervision from a parametric token and a nonparametric sequence embedding space.
