Elephants turn footsteps into messages through ground and skull vibrations‎

Elephants can communicate with other elephants across distances of up to five kilometers (3 miles) by producing sounds that travel through the air. However, they have a second way of sending signals: seismic waves traveling through the ground. These vibrations are transmitted from elephants' feet through their legs and ultimately through the bones of their skull directly into the inner ear. They can be perceived across distances of 10 kilometers (6 miles) or more. This is called bone-conduction hearing.

AI explored as tool for unraveling radicalization's complex drivers‎

Radicalization is a complex process, influenced by many variables that interact to varying degrees. AI scientist Mijke van den Hurk investigated whether artificial intelligence could help unravel this intricate interplay. She defended her Ph.D. thesis cum laude on June 29.

Nitrate in drinking water may be linked to preterm births in New Zealand‎

A new Aotearoa New Zealand study has found that nitrate concentrations in drinking water are associated with an increased risk of preterm birth, even at levels well below the current drinking water standard. The study, published in Environmental Research, analyzed 735,831 singleton births between 2008 and 2021, linking gestational age with estimated nitrate concentrations in drinking water at the mother's usual residence.

When words signal conflict: Measuring exclusionary nationalism in prewar Japan‎

Why do countries go to war? While economic, military and geopolitical factors are often part of the answer, researchers have also pointed to exclusionary nationalism—the belief that one's own nation is superior to others. One observable trace of such sentiment is language: As exclusionary attitudes intensify, people tend to favor words from their own language over foreign ones and even reject the "enemy's" words outright.

Low carbon dioxide levels improve microbial production of biodegradable plastic‎

In an innovative gas fermentation process, reducing the concentration of carbon dioxide was found to significantly improve microbial production of the biodegradable plastic poly[(R)-3-hydroxybutyrate]. Researchers found that hydrogen-oxidizing bacteria grown under safe, nonflammable gas conditions enable more efficient production of biodegradable plastic at lower CO2 levels. The study provides a promising strategy for sustainable carbon recycling and efficient CO2 utilization.

Report details ecological characterization of peatlands and coastal lagoons in EU‎

A new synthesis report, titled "Ecological Characterisation of Peatlands and Coastal Lagoons in Europe," has been published to support the assessment, monitoring and restoration of European wetlands under EU environmental legislation. The report was prepared in response to a policy request submitted by the Directorate-General for Environment (DG ENV) to the European Commission's Knowledge Centre for Biodiversity (KCBD) and delivered by the Science Service for Biodiversity (SSBD), which is currently under development by the BioAgora project.

Are we missing the universe's 'noosignatures?'‎

Astrobiology has long been split into two camps: a search for "biosignatures" and a search for "intelligence." These look for very different things, but they also leave a huge gap in between. It took 3.5 billion years for us to go from the first microbe to a civilization that sent radio waves into the cosmos. Detecting life in between those stages is a relatively untouched aspect of astrobiology—which is also the focal point of a new paper, "Signs and Signatures of Intelligence," available on the arXiv preprint server, by astrobiologist Julia DeMarines.

More than 50% of Australian university assignments used AI. How should universities respond?‎

Last week, the U.S. software company Turnitin revealed 53.6% of Australian tertiary education submissions run through its system used some form of AI in the period from October 2025–April 2026. The company, whose plagiarism-detection technology is widely used in universities, also reported 10% of these submissions contained more than 80% AI-written content.

New technique for building ultra-thin material stacks promises quantum breakthrough‎

Scientists have unveiled a new fabrication technique for the ultra-clean manufacturing of 2D heterostructures—materials just a few atoms thick—that could be used in quantum technology and electronics. Experts from Southampton and Singapore say the method could be used to develop next-generation devices that accelerate research in quantum computing.
