Fast radio bursts (FRBs) are intense flashes of radio light that last for only a fraction of a second.
They are likely caused by the intense magnetic fields of a magnetar, which is a highly magnetic neutron star. Beyond that, FRBs remain a bit of a mystery.
We know that most of them originate from outside our galaxy, though the few that have occurred within our galaxy have allowed us to pin the source on neutron stars.
As the capabilities of generative AI models have grown, you’ve probably seen how they can transform simple text prompts into hyperrealistic images and even extended video clips.
More recently, generative AI has shown potential in helping chemists and biologists explore static molecules, like proteins and DNA. Models like AlphaFold can predict molecular structures to accelerate drug discovery, and the MIT-assisted “RFdiffusion,” for example, can help design new proteins.
One challenge, though, is that molecules are constantly moving and jiggling, which is important to model when constructing new proteins and drugs. Simulating these motions on a computer using physics—a technique known as molecular dynamics —can be very expensive, requiring billions of time steps on supercomputers.

The particle-physics funder will provide financial incentives to encourage practices such as data sharing and transparent peer review.
Researchers led by electrical engineers at the University of California San Diego have developed a better way to perform the comparative analysis of entire genomes. This approach can be used to study relationships between different species across geological time scales.
This new approach is poised to unlock discoveries regarding how evolution has shaped present-day genomes and also how the tree of life is organized. The new method, named CASTER, is described in a paper published in Science on 23 January 2025.
CASTER is poised to offer biologists a far more scalable approach than state-of-the-art for comparing full genomes. This is especially relevant given the exploding number of sequenced genomes of both living and also extinct species.
An object we thought belonged to the most common category of planet in the galaxy has turned out to be something we’ve never seen before.
The exoplanet Enaiposha, or GJ 1,214 b, is a hazy world orbiting a red dwarf star about 47 light-years from Earth. Previously likened to a mini-Neptune, in-depth observations obtained using JWST now suggest the exoplanet is more like Venus – only much larger.
This would make it the first known of its kind, a category astronomers are calling ‘Super-Venus’
Researchers report they developed a strategy to stabilize quantum networks, which lose communication links after use.
Discover how the first stars—Population III stars—shaped the universe by creating water billions of years ago. Learn how these massive stars exploded as supernovae, spreading oxygen that combined with hydrogen to form water molecules. With insights from simulations and observations, we’ll explore how water’s early abundance could mean life-supporting conditions existed far earlier than thought. Don’t miss this fascinating journey into the origins of water in the cosmos!

Scientists used AI to refine cosmological parameter estimates, providing deeper insights into the nature of dark matter and dark energy.
Many science fiction authors try to incorporate scientific principles into their work, but Ian Tregillis, who is a contributing author of the Wild Cards book series when he’s not working as a physicist at Los Alamos National Laboratory, took it one step further: He derived a formula to describe the dynamics of the fictional universe’s viral system.
In independent research published in the American Journal of Physics, Tregillis and George R.R. Martin derive a formula for viral behavior in the Wild Cards universe.
Wild Cards is a science fiction series written by a collection of authors and edited by Martin and Melinda M. Snodgrass. Sitting at over 30 volumes, the books are about an alien virus called the Wild Card that mutates human DNA. Martin is credited as a co-author of the paper, making it his first peer-reviewed physics publication.
