Teachers more likely to accept low AI grades than equivalent human grades, study finds
Teachers were more likely to accept an overly harsh grade given to a student by AI than when the unduly low grade was handed out by a human. As AI is increasing...
These underwater 'living pink rocks' help store carbon: Scientists just found four new species
Rhodoliths may look like small rocks on the seafloor, but they are actually living algae that create habitats for marine life and contribute to long-term carbon...
Some drugs 'fail' because of unrealistic testing conditions, scientists discover
A drug once dismissed as ineffective suddenly worked—when scientists tested it under more realistic conditions that mimic the human body. In this surprising new...
New maps chart old-growth forests across Alaska and British Columbia
Mature and old-growth forests are vital for biodiversity, carbon storage, cultural traditions and economic activity. But in Alaska and British Columbia, these r...
Possible dark matter-deficient twins discovered in the Fornax Cluster
Astronomers have identified a possible new example of one of the universe's strangest galaxy types: galaxies that appear to contain little or no dark matter. Th...
Chasing the ghost dog of the Amazon: New insights into a mythical canid
For decades, the short-eared dog (Atelocynus microtis) has been considered one of the least-known carnivores in Latin America, and potentially one of the least-...
Quantum memory surpasses classical limits for storing unknown quantum operations
Quantum memories, systems that store and retrieve information leveraging quantum mechanical effects, can outperform classical storage systems on some existing t...
Space telescopes are now overwhelmed by satellite trails
Unfortunately, there's more bad news to report on the clear skies front. A new paper, available on the arXiv preprint server from researchers at NASA's Ames Res...
Dogs uncover invasive pests that experts missed in real-world vineyard tests
At a Maryland vineyard, Debi Persing guided her Boston terrier, Xephyr, slowly down a row of grapevines. Vineyard workers and scientists had already identified...
A lack of sex held back life's diversity for millions of years, fossil study finds
The way that Earth's first animals reproduced held back life's diversity for millions of years, until stress and competition led to the development of sexual re...
Policy recommendations in climate-related research often 'an afterthought', analysis finds
Too often, policy recommendations in climate-related research are either an afterthought or stray too far into advocacy, a new analysis has found. Researchers l...
New 3D microscope technology captures high-resolution tissue images at a fraction of the cost
A team led by Raju Tomer, professor of biological sciences at Columbia University, has created a new design for microscopes and microscope lenses that could pus...
