Ancient Maltese seafarers likely navigated by the stars‎

Malta might be the last place one would expect a convergence of archeoastronomy and early cosmology. Today, it's better known as a billionaire tax haven and a favorite production location for big-budget Hollywood movies.

Microplastics may transport hazardous plastic additives through marine environments‎

Plastic pollution is not only a marine litter issue; it is also closely linked to resource circulation and chemical management. Plastic products contain a wide range of additives, including antioxidants, plasticizers, ultraviolet stabilizers and flame retardants. Some of these chemicals are regulated or managed because of concerns about their effects on human health and ecosystems.

Scientific advancement has never been more prolific—so why has trust in science plummeted?‎

From genome editing to quantum computing, scientific progress is accelerating at an unprecedented pace, yet public faith in science is collapsing. Our species has mapped the human genome, created powerful computers that sit in the palms of our hands and extended human life spans beyond what our ancestors could have imagined—meanwhile, anti-intellectual movements are gaining momentum.

Machine learning predicts forest soil fungal diversity from drone images‎

Combining drone data and machine learning can help cover more ground in monitoring forest soil health, University of Alberta research shows. The findings are published in the journal Forest Ecology and Management. Using both tools to map and monitor soil fungal diversity—a key indicator of a healthy forest ecosystem—proved highly effective and could help reduce the need for boots-on-the-ground soil sampling over huge areas of forest, says Dr. Cameron Carlyle, a professor in the Faculty of Agricultural, Life & Environmental Sciences and a co-author of the study.

Traditional plastic forks shed harmful microplastics. Plastic created from sugar is an alternative‎

At a Massachusetts lab, pebble-sized pellets are transformed into forks and films that won't leave persistent microplastics in the environment.

Oak leaves harbor distinct microbial worlds on their opposite surfaces‎

A single leaf may look like a simple patch of green, but to the microscopic life that inhabits it, it is a vast landscape divided into different worlds.

Common-ground curriculum boosts tolerance and civic engagement in pilot study‎

Social cohesion is the glue that holds society together. Now, those bonds are breaking, and polarization has been growing for years. Educational programs aimed at strengthening social cohesion by promoting greater tolerance often focus on social differences, such as ethnicity, religion or nationality. Yet are such programs effective? A German–American team of researchers involving the University of Konstanz recommends the opposite approach: Instead of focusing on differences, such programs should center on universal human values.

DNA repair enzymes favor specific sequences, shaping mutation patterns in the human genome‎

When a wound does not heal properly, it leaves a scar. Similarly, mutations—which are permanent changes to genetic code—are often the result of damaged DNA that has not been properly repaired. Mutations can impede the function of genes and lead to disease and aging, but they are also the source of genetic variation, which allows new traits to emerge and facilitates the evolutionary process. Scientists still do not fully understand why some damaged DNA segments are successfully repaired while others are not.

US had hottest month on record in July‎

July 2026 marked the hottest month on record for the contiguous United States, the National Oceanic and Atmospheric Administration said Monday, continuing a recent trend driven by human-caused climate change.
