Providing AI training leads to more critical and ethical use by university students‎

No longer a technological novelty, generative artificial intelligence (GenAI) has become a common tool for everyday academic tasks among the university community. In view of this, the Universitat Oberta de Catalunya (UOC) has carried out a research project to establish the extent to which GenAI-specific training can help ensure more responsible and critical use by students.

Working in groups can help Republicans and Democrats agree on controversial content moderation online‎

Over half of Americans believe tech companies should take action to restrict extremely violent content on their platforms, according to Pew data, yet even trained content moderators consistently disagree in their decisions about how to classify hate speech and offensive images.

How soil and human antibiotic resistance are connected‎

A study led by researchers at the Department of Civil Engineering at The University of Hong Kong (HKU) has uncovered alarming evidence that soil worldwide is emerging as a significant reservoir and amplifier of high-risk antibiotic resistance genes (ARGs), which enable bacteria to develop resistance to antibiotics, and that their threat to public health has continued to increase over the past decade or so.

Scientists chart over 140,000 DNA loops to map human chromosomes in the nucleus‎

One of the most detailed 3D maps of how the human chromosomes are organized and folded within a cell's nucleus is published in Nature.

Anything-goes 'anyons' may be at the root of surprising quantum experiments‎

In the past year, two separate experiments in two different materials captured the same confounding scenario: the coexistence of superconductivity and magnetism. Scientists had assumed that these two quantum states are mutually exclusive; the presence of one should inherently destroy the other.

Leaves' pores explain longstanding mystery of uneven tree growth in a carbon-enriched world‎

The basics of photosynthesis are something that every student learns in school: carbon dioxide, water and light in; oxygen and sugar for growth out. In a world where atmospheric carbon dioxide levels are rising, it is plausible to think that trees and other plant life growth will rise in lockstep.

A third path to explain consciousness: Biological computationalism‎

Right now, the debate about consciousness often feels frozen between two entrenched positions. On one side sits computational functionalism, which treats cognition as something you can fully explain in terms of abstract information processing: get the right functional organization (regardless of the material it runs on) and you get consciousness.

Two ancient human species came out of Africa together, not one, suggests new study‎

The textbook version of the "Out of Africa" hypothesis holds that the first human species to leave the continent around 1.8 million years ago was Homo erectus. But in recent years, a debate has emerged suggesting it wasn't a single species, but several. New research published in the journal PLOS One now hopes to settle the matter once and for all.

How greener bus stops can help people beat the heat‎

A new University of British Columbia study published in Urban Climate finds that people waiting at bus stops they find visually pleasant are more likely to feel thermally comfortable during hot weather, even when physical heat levels are high.

An ecosystem never forgets: Extreme heat and drought responses linked to hydrological memory‎

The low-latitude highlands region of southwestern China experienced two major climate events in recent years: a severe drought in 2009–2010 and an extreme heat wave in 2019. Though both sprang from similar large-scale atmospheric circulation patterns, the events produced different responses, raising questions about how multiple stressors can push ecosystems toward contrasting outcomes.
