Phys.org / The rich are more likely to use AI, exposing a new digital divide

The widespread adoption of artificial intelligence (AI)—particularly in "hidden" everyday applications—is creating a new and distinct form of digital inequality. This is the warning of communication researcher Professor Sai ...

Phys.org / A lost galaxy called 'Loki' may be hiding inside the Milky Way

The Milky Way galaxy grew into its current form with the help of smaller galaxies over time, which it has "consumed" or merged with. Astronomers are able to pick out which stars in the Milky Way came from other galaxies by ...

Phys.org / Sudden quantum jolts may not break adiabatic behavior after all

In thermodynamics, an "adiabatic process" is a system change that transfers no heat in or out of the system. Any and all energy change in that system are therefore accomplished by doing work on the system, work being action ...

Phys.org / Evolution has reused the same genes for 120 million years, study shows

Scientists have shown that evolution has been using the same genetic "cheat sheet" for over 120 million years, suggesting that life on Earth may be more predictable than first imagined. The international team, led by scientists ...

Phys.org / Frozen-in gravity: A new way to understand the evolution of spacetime dynamics

The concept of spacetime, first described in Einstein's theory of general relativity, has since been widely studied by many physicists worldwide. Spacetime is described mathematically as a four-dimensional (4D) continuum ...

Medical Xpress / No live animal testing needed: Lab-grown airway organoids reveal viral infection in wildlife species

Experimental infections, where a pathogen is introduced into the host body to see its effects in action, are considered the gold standard for assessing how vulnerable a host is, offering clear insights into how a pathogen ...

Phys.org / A physics explanation shows why US elections keep ending 50:50—and why more spending won't change that

A physics-inspired model calibrated on 40 years of US congressional data pinpoints a spending threshold of roughly 1.8 million USD at which campaigns stop influencing who wins and start fueling polarization instead.

Phys.org / In good spirits: Why haunted houses are perfect places to connect with others

A pounding heart, shaking limbs, chills and a churning stomach—it's no wonder that fear is an emotion we usually try to avoid. At least most of the time. We may not like having the wits scared out of us in a real-life crisis, ...

Medical Xpress / Diabetes flips immune cells from repair to inflammation in peripheral artery disease, study finds

Type 2 diabetes can turn immune cells that help with tissue repair and anti-inflammatory responses into triggers of chronic inflammation. A recent study investigated why people with type 2 diabetes are at a higher risk of ...

Phys.org / US–Indian space mission maps extreme subsidence in Mexico City

One of the most powerful radar systems ever launched into space has mapped the ground moving beneath one of the fastest subsiding capitals in the world: Mexico City. The findings show how quickly and reliably the NISAR (NASA-ISRO ...

Science X / Your hand betrays your sense of fairness, and it does so before you even realize it

It turns out that your body is much more truthful about what is and isn't fair than you might imagine. The rate at which we make physical movements is able to reveal whether our motives are self-interested or retaliatory.

Phys.org / A silent robot shadows sperm whales by listening to their clicks

An autonomous underwater glider is giving us a new and effective way to track sperm whales by tuning into their clicks and silently following them. To study these large oceanic predators, researchers need to monitor their ...
