Phys.org / Homelessness could be 4 times higher in a decade due to impacts from climate change, study suggests
A study on the future of Australia's housing market has revealed that even well-intended housing market interventions could significantly worsen housing affordability and homelessness in the country due to the impacts of ...
Phys.org / Experimentally validated AI model predicts virulence of tomato yellow leaf curl virus
A CBBL research team led by Professor Balachandran Manavalan from the Department of Integrative Biotechnology at Sungkyunkwan University has developed DeepTYLCV, an accurate and interpretable artificial intelligence model ...
Medical Xpress / Too little sleep—and too much—associated with faster aging
An analysis of biological clocks throughout the human body suggests that too few hours of sleep—and too many—may speed aging in the brain, heart, lung, and immune system and is associated with a wide range of diseases.
Phys.org / Northern Sri Lanka's oldest confirmed settlement reshapes what archaeologists thought about early island life
A study published in the Journal of Island and Coastal Archaeology has identified the earliest evidence of prehistoric occupation by island dwellers of northern Sri Lanka. Long thought to be unsuitable for human occupation ...
Phys.org / Buried in Sudan's desert, 280 vast stone circles reveal a vanished cattle-herding culture
Recent satellite remote sensing surveys have identified 280 stone structures spread across the Atbai desert in Sudan. Twenty of these structures were previously identified by fieldwork or informal surveys, but were not systematically ...
Phys.org / How reindeer herds, nature and Sámi culture can thrive when forests are restored across northern Europe
Political debates about the future of forests in Sweden and the EU are reaching an impasse. Producing more wood comes at the expense of nature and the storage of carbon within trees and soils. Conserving and restoring more ...
