Artificial intelligence system rapidly predicts how two proteins will attach: The machine-learning model could help scientists speed the development of new medicines
Antibodies, small proteins produced by the immune system, can attach to specific parts of a virus to neutralize it. As scientists continue to battle SARS-CoV-2, the virus that causes Covid-19, one possible weapon is a synthetic antibody that binds with the virus’ spike proteins to prevent the virus from entering a human cell. To develop […]
Fat-secreted molecule lowers response to common cancer treatment
Leptin, a molecule produced by fat cells, appears to cancel out the effects of the estrogen-blocking therapy tamoxifen, a drug commonly used to treat and prevent breast cancers, suggests a new study led by researchers from the Johns Hopkins Kimmel Cancer Center. The findings, published online Aug. 13 in npj Breast Cancer, could help explain […]
Acoustic illusions
When listening to music, we don’t just hear the notes produced by the instruments, we are also immersed in its echoes from our surroundings. Sound waves bounce back off the walls and objects around us, forming a characteristic sound effect — a specific acoustic field. This explains why the same piece of music sounds very […]
