A large-scale study with data from Brazilian Cerrado streams found that about half of the field sampling effort preserved the ability of most habitat and biological indices to distinguish stream disturbance levels, while greatly reducing time and costs. Macroinvertebrate indices remained robust under reduced sampling, and only fish richness was more sensitive to lower effort. The findings suggest that faster, more cost-effective stream assessments could support biomonitoring programs in tropical regions with limited funding.

Writing in Frontiers in Environmental Archaeology, researchers in Norway and Canada recently investigated the evolution of butchering technology using newly analyzed zooarchaeological data from Bronze Age Tell Aphek, an archaeological site in north Israel. They showed that stone tools dominated during the Early Bronze Age (3000–2500 BCE) followed by a dramatic and sudden shift towards metal tools with the onset of Middle Bronze Age occupation (2000–1550 BCE). By the end of the Late Bronze Age (1550–1200 BCE), metal tools had almost completely replaced stone tools as the main butchering tools.

KAIST announced on May 19th that the KAIST-Hanwha Solutions Future Technology Research Institute, has secured bio-technology capable of mass-producing eco-friendly raw materials for plastics and textiles using waste resources, offering an alternative to petroleum-derived naphtha.

An Osaka Metropolitan University-led research team demonstrated that when female Tongeia fischeri, a near-threatened butterfly species in Japan, feed on an invasive plant during the larval stage, the reflectance spectrum of their adult wings changes, making them less preferred for mating by wild males. 

Researchers developed an automated cold plasma and bubble system for dual modality function of treating food-industry wastewater and transforming into nutrient-rich liquid fertilizer for hydroponic farming. This automated electrified flow system runs on a low energy, reduced wastewater organic load while simultaneously improving plant growth, offering a scalable and promising route toward sustainable agriculture and water reuse.

​For the first time, scientists have directly measured how smoking changes the mechanical behavior of human lung tissue. The researchers found that smoking substantially stiffens this tissue in ways resembling fibrosis, a disease that scars and toughens the lungs.
