Tech Xplore / Misleading text in the physical world can hijack AI-enabled robots, cybersecurity study shows
As a self-driving car cruises down a street, it uses cameras and sensors to perceive its environment, taking in information on pedestrians, traffic lights, and street signs. Artificial intelligence (AI) then processes that ...
Phys.org / Prehistoric tool made from elephant bone is the oldest discovered in Europe
A remarkable prehistoric hammer made from elephant bone, dating back nearly half a million years ago, has been uncovered in southern England and analyzed by archaeologists from UCL and the Natural History Museum, London.
Phys.org / Compact electron accelerator offers new approach for treating PFAS-contaminated water
So-called forever chemicals or PFAS compounds are a growing environmental problem. An innovative approach to treating PFAS‐contaminated water and soil now comes from accelerator physics: high‐energy electrons can break ...
Phys.org / Unlocking genetic code of crop-damaging fungus paves way for better disease control
Researchers from CSIRO, Australia's national science agency, have unlocked the most detailed genetic blueprint yet of a major soil-borne crop pathogen—an advance that paves the way for better crop disease management in ...
Phys.org / Kenya's big cats under pressure: Cattle are pushing lions away
