Scientists covered part of a Chinese glacier with fabric to slow melting
A recent study illustrated that utilizing artificial fabric to cover Dagu Glacier yielded a notable decrease in ice melting, with a remarkable 27% reduction within the initial two months, thereby safeguarding substantial ice reserves. Nevertheless, the fabric's effectiveness diminished over time due to factors such as reduced reflectivity, ultimately resulting in an annual melting reduction of 15%. Researchers also pointed out the practical difficulties in scaling this solution.
Quebec home built from 200,000 recycled bottles, assembled in just three days
In a remarkable development, a two-bedroom house located in Saint-Rémi-d'Amherst, Quebec, has been built using an innovative construction method known as PakVert. This technique employs panels crafted from recycled plastic bottles, resulting in a building process that took merely three days. By minimizing construction waste and cutting costs by approximately 35 percent, this initiative contributes significantly to affordable housing and environmental sustainability in Canada.
Nevada mine site gets a new park amid $257 million cleanup and plans for 3,000 homes
Henderson, Nevada, is transforming the former Three Kids Mine into a thriving residential area, complete with new parks. The recently opened Greenbow Park offers recreation options such as pickleball courts and scenic walking trails. With plans for over 3,000 homes across 24 neighborhoods, the Aries master-planned community is set to revitalize the site, which underwent a $257 million cleanup from its industrial past into a lively suburban setting.
Scientists discover silk traces on 101 ancient objects in China, uncover clues to ancient rituals
Scientists studying 3,000-year-old objects from China's Sanxingdui archaeological site have found silk traces on 101 artefacts, including bronze masks, gold, jade and ivory objects. Published in the journal Antiquity, the study suggests that ancient Shu people used silk to wrap or cover objects during rituals. Researchers also identified red pigments and different weaving patterns, offering clues about ancient textile practices.
Australia’s stingless bees may help fight antibiotic resistance
Researchers at the University of Sydney are investigating the medicinal properties of honey from stingless bees. The honey has shown effectiveness against various bacterial and fungal pathogens, including difficult-to-treat strains. Findings suggest that sugarbag honey is comparable in strength to well-known medical-grade honeys. While propolis displayed selective antimicrobial activity, the reason for honey's potency remains unclear. Further research is needed to identify the beneficial compounds within the honey.
