People who are seriously ill may overestimate the benefits of early clinical trials while underestimating the risks. This makes properly understanding informed consent, the full knowledge of risks and benefits of treatments,…

Remembering…
A study published in Science Advances found that certain types of materials have a "memory" of how they were processed, stored, and manipulated. Researchers were then able to use this memory to control how a material ages and to encode specific properties that allow it to perform new functions. This creative approach for designing materials…

Not all heads are shaped alike: some soldiers have ones that resemble manhole covers and perfectly seal tunnel entrances. Others have square heads, which they assemble into…
