Teachers more likely to accept low AI grades than equivalent human grades, study finds
Teachers more likely to accept low AI grades than equivalent human grades, study finds Gaby Clark Scientific Editor Andrew Zinin Lead Editor 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 increasingly integrated into decision-making, concerns about AI errors are often countered by assurances that humans will oversee and check the algorithm's work. Publishing in PNAS Nexus, Rigissa...
A classic brain test exposed AI's biggest weakness
A classic brain test exposed AI's biggest weakness - Date: - June 10, 2026 - Source: - PNAS Nexus - Summary: - Researchers gave top AI models a classic attention test used in psychology and found a major flaw. While the models could correctly name colors in short lists, their performance deteriorated sharply as the task became longer and more complex. Some leading systems fell from over 90% accuracy to nearly complete failure.
Embryos shape their limbs: a key discovery of "genetic brakes"
Canadian scientists have made a significant advance in understanding the mechanisms that enable embryos to properly form their limbs, thanks to new research led by Université de Montréal medical professor Marie Kmita at the Montreal Clinical Research Institute (IRCM). In findings published in the journal PNAS, Kmita and her team highlight the crucial role of certain molecular systems that act as true “genetic brakes,” ensuring that development proceeds correctly. At the very beginning of...
Enduring hardship reduces support for easing hardship for others, study suggests
Enduring hardship reduces support for easing hardship for others, study suggests Sadie Harley Scientific Editor Andrew Zinin Lead Editor Although intuition suggests that experiencing adversity will increase a person's willingness to help others going through similar hardships, surveys show that this is not always the case. For example, immigrants who struggled through arduous naturalization processes do not necessarily support making the path to citizenship easier for others, and those who...

How many generations of humans have there been? Modern humans have been around 300,000 years. How many generations is that?
Deep learning four decades of human migration
Abstract Human migration is a fundamental driver of global demographic change, shaping population structure, labour markets and social policy across countries1,2,3. Although long-term migration patterns are often linked to economic development4, they can shift rapidly in response to shocks such as conflict, environmental crises and political change5. Despite its importance, migration remains difficult to measure consistently: existing data are sparse, concentrated in high-income settings and...
First whole-genome sequence of a Greenland shark holds clues to their extreme longevity
First whole-genome sequence of a Greenland shark holds clues to their extreme longevity A genomic study of Greenland sharks, thought to be the longest-lived vertebrates on the planet, is hinting at the secrets to their epic lifespan and cancer resistance. The first-ever whole-genome sequence of a Greenland shark has revealed genetic clues to how the animals avoid cancer and live for hundreds of years. The work may pave the way to a better understanding of age-related diseases in humans.
Scientists turn tofu and cheese waste into tiny CO2-catching beads
Scientists turn tofu and cheese waste into tiny CO2-catching beads - Date: - June 11, 2026 - Source: - ETH Zurich - Summary: - Scientists have developed biodegradable protein beads made from dairy and tofu waste that can capture carbon dioxide from the atmosphere more efficiently than many current technologies. Unlike conventional systems that require large amounts of energy, the new method releases captured CO2 using a simple room-temperature process. Limiting long-term global warming to...
