A race against time to save Alpine ice cores that record medieval mining, fires, and volcanoes‎

Ice cores taken from glaciers reveal the air pollution of the past, using atmospheric particles incorporated in snow that fell on the glacier and became ice. Now, scientists have extracted a record of thousands of years' worth of air pollution from 9.5 meters of ice at the Weißseespitze glacier, close to the border between Austria and Italy. But this ice is under threat from global warming, and scientists warn that it is now a race against time to capture critical climate information locked in these glaciers before it's gone forever.

Harnessing eDNA to help conserve Australia's oceans‎

As we move through the world, we leave behind invisible traces of ourselves encased in the hair, skin, and other bodily matter we shed. These tiny pieces of DNA—known as environmental DNA or eDNA—have major conservation potential. Now, West Australian research hopes to push the boundaries of the technique.

Social media influencers increase the toxicity and power of misinformation, research shows‎

Social media influencers (SMIs) can perpetuate the flow of misinformation online because of the unique relationship they have with their followers, research led by Cardiff Business School finds. For an article published in the journal Psychology & Marketing, academics analyzed brand-related misinformation and associated user comments spanning 47 brands across nine industries over a three-year period. It is the first study to measure the extent and types of toxicity generated by influencers versus regular users.

Flood tolerant wetland crops could also support nature recovery, finds new research‎

Research led by the University of Cambridge and the RSPB shows that farming wetland-adapted crops on wetter peat—known as paludiculture—can support richer and more diverse bird communities than drained grassland.

Global observations reveal rapid reorganization of ocean nutrients‎

From coral reefs and kelp forests to the open ocean and deep-sea zones, nutrients that support phytoplankton growth and marine productivity form the foundation of oceanic ecosystems. When levels of key nutrients—such as nitrate and phosphate—get too high or too low, these ecosystems may face major disruption. However, at a global scale, long-term trends in marine nitrate and phosphate levels have been unclear.

Three new rock monitor lizard species discovered in northern Queensland‎

Three striking new species of rock-dwelling monitor lizards have been formally described from the savannas of northeastern Queensland, revealing a previously unrecognized evolutionary lineage. The discovery, led by researchers from The Australian National University (ANU), identified the rainbow rock monitor (Varanus iridis), the orange-headed rock monitor (Varanus umbra) and the yellow-headed rock monitor (Varanus phosphoros).

Seeing global trade through the lens of physics‎

New research from the Complexity Science Hub (CSH) shows why widely used algorithms for measuring economic complexity produce trustworthy results and how these tools may benefit diverse areas such as ecology, social science, and agentic AI. The paper is published in the journal Physical Review E.

Specialist resource centers linked to stronger sense of belonging, attainment for autistic pupils‎

Specialist resource centers (a form of "Inclusion Base") within mainstream secondary schools may be linked to stronger academic progress, improved attendance, and a greater sense of belonging for autistic pupils, according to a new three-year study from the University of Surrey, published in the journal Autism.

Cell death's 'beautiful' rings have implications for biological resilience and immunity‎

Researchers at the University of Michigan have revealed that cells use a previously unknown feat of molecular craftsmanship to help protect their larger host organisms. The building blocks required for this work are found across the tree of life, meaning this finding could help better understand and support plant resilience and human immune response, the researchers said.

How much do nontargeted analyses really see? A model maps chemical blind spots‎

In a study published in Analytical Chemistry, researchers from the University of Amsterdam's Van 't Hoff Institute for Molecular Sciences (HIMS) reveal a sobering reality regarding nontargeted chemical analysis. Although widely used for screening the environment for chemicals, this concept isn't nearly as broad as its name suggests, leaving massive blind spots in the data.
