Critical thinking for the unstoppable use of artificial intelligence

Critical thinking for the unstoppable use of artificial intelligence

Artificial IntelligenceSociology

The expansion of generative artificial intelligence (GenAI) such as that offered by ChatGPT has multiplied the amount of content available very easily and quickly. In this scenario, two skills become decisive for safe and effective use: critical thinking—the ability to analyze and evaluate information—and media literacy—knowing how to locate, evaluate, and produce information responsibly. A […]

Antimicrobial peptides (AMPs) are highly potent and broad-spectrum antibiotics, found as components of the innate immune system in almost all forms of life. AMPs are short proteins, tiny compared with conventional antibiotics but extraordinarily effective: they bind to and disrupt bacterial membranes, which quickly incapacitates or kills a cell. For decades, the picture many scientists […]

In the layered kagome metal CsV₃Sb₅, researchers have observed something that, until now, seemed almost impossible: robust quantum interference in the normal, non-superconducting state, persisting over distances of several micrometers. The interference is not the fragile single-particle kind seen in ultra-clean semiconductors at millikelvin temperatures. Instead, it behaves as if the entire stack of kagome […]

When we think of atoms sitting on a surface, we tend to imagine them as fairly still, especially at very low temperatures (colder than liquid nitrogen, in fact). Yet in modern surface science we often discover the opposite: atoms can be surprisingly restless, gliding from place to place in ways that shape how materials grow […]

By Mapping Ignorance

A new study has identified a surprising source of entropy in quantum timekeeping—the act of measurement itself. The researchers demonstrate that the energy cost of “reading” a quantum clock far outweighs the cost of running it, with implications for the design of future quantum technologies. Clocks, whether pendulums or atomic oscillators, rely on irreversible processes […]

Order on a molecular scale is difficult to control. The systems with highest possible order are crystals, formed by long arrays of repeating constituent components in all directions. The most familiar examples of crystals encountered in daily life are table salt and sucrose, the sugar in our kitchens. Every grain of table salt is a […]

Author: Gabriela Radulescu, Guggenheim Postdoctoral Fellow, Smithsonian Institution As humans began to explore outer space in the latter half of the 20th century, radio waves proved a powerful tool. Scientists could send out radio waves to communicate with satellites, rockets and other spacecraft, and use radio telescopes to take in radio waves emitted by objects […]

Author: Anthony Booker, Reader in Ethnopharmacology, University of Westminster “Double double toil and trouble” is a quote from Shakespeare’s Macbeth that conjures images of evil witches making potions in giant cauldrons. But the truth was that women persecuted as witches were probably legitimate healers of the time. Prior to the 14th century, female healers were […]
