Researchers in the U.K. have developed an AI-driven method of identifying viruses in wild animals with the potential to spillover into humans. The technique makes it possible to use the genome sequences of the spike proteins by which viruses enter host cells to assess the potential to infect humans without having to isolate an individual virus and tests its infectivity in the lab.

A new metasurface design strategy that replaces rigid order with “engineered disorder” could significantly increase how many optical functions can be integrated into a single ultra-thin device without increasing size or complexity, according to a study published in Nature Communications. The study challenges a longstanding assumption in optical engineering that highly ordered, periodic structures are required to precisely control light.

When a tumor migrates and colonizes another tissue or organ, it can be identified as a metastasis, but its origin is not always clear. Now, a study based on machine learning has identified DNA-methylation patterns that reveal the type of tissue a cancer comes from when the primary tumor cannot be found. This technique could help guide more specific treatments for patients with cancers of unknown primary, who today often receive broad, nontargeted chemotherapy.
