Russian scientists have found the carcass of an ancient foal perfectly preserved in the Siberian permafrost.
The fossil discovered in the region of Yakutia has its skin, hair, hooves and tail preserved. Yakutia is also famous having wooly mammoth fossils found in the permafrost.
Scientists from Russia’s Northeast Federal University who presented the discovery Thursday said the foal is estimated to be 30,000 to 40,000 years old. They believe it was about two months old when it died.
A team of Chinese scientists have developed a large-scale transparent smart window that can change light intensity while effectively capturing the particulate matter in smog, a study said.
The study published on Saturday in the journal iScience described a simple solution-based process to fabricate large-area flexible transparent windows with Ag-nylon electrodes for high-efficiency PM2.5 capture, reports Xinhua news agency.
It takes only 20 minutes to fabricate 7.5 square metres of Ag-nylon flexible transparent windows showing an optical transmittance of over 86 per cent, according to the group of scientists led by Yu Shuhong from the University of Science and Technology of China (USTC).
The Ag-nylon mesh can not only change the indoor light intensity, but also purify indoor air as a high-efficiency PM2.5 filter.
The scientists found that the obtained Ag-nylon electrodes could be used as an ideal intelligent thermochromic smart window with excellent mechanical stability.
It remains stable after undergoing a bending test with 10,000 bending cycles with a minimum bending radius of 2.0 mm.
