Human body odor critical for mosquito host-seeking behavior over long distances, study finds

We know a lot about mosquito preferences up close, but how do mosquitoes find us from up to a hundred meters away? Using an ice-rink-sized outdoor testing arena in Zambia, researchers found that human body odor is critical for mosquito host-seeking behavior over long distances.

Researchers develop a deep learning model to classify cancer cells by type

Cancer cells that initiate metastasis, or the spread of the disease from its primary location, are different from cancer cells that stay in the original tumor. Distinguishing metastasis-initiating cell types can determine the severity of cancer and help medical practitioners decide on a course of treatment.
