Children's pain 'swept under the carpet for too long'

When 12-year-old Caitriona Roberts went to her doctor because she was experiencing pain and swelling in her ankle, no one knew quite what was up.

Finding its way to the top: How a cell surface receptor reaches its destination

Dr. Guangyu Wu is dissecting the molecular homing that enables a nascent protein to ultimately find its way to the surface of a cell as a mature receptor type that helps us taste, smell and even regulate our mood and immunity.

Only 7% of US school districts in poorer, ethnic minority populations to reopen this fall

US schools in poor districts with large non-white student populations are less likely to reopen fully this academic year, according to a major new study published in the peer-reviewed Journal of School Choice.

To make mini-organs grow faster, give them a squeeze

The closer people are physically to one another, the higher the chance for exchange, of things like ideas, information, and even infection. Now researchers at MIT and Boston Children's Hospital have found that, even in the microscopic environment within a single cell, physical crowding increases the chance for interactions, in a way that can significantly alter a cell's health and development.

Trees and lawns beat the heat

In cities, humans replace the natural ground cover with roofs, pavement and other artificial materials that are impervious to water. These surfaces significantly change how the land absorbs and releases energy and cause the urban heat island effect, a phenomenon where developed areas get hotter than nearby rural areas. As climate change pushes many cities towards dangerous temperatures, planners are scrambling to mitigate excessive heat.

Robot swarms follow instructions to create art

What if you could instruct a swarm of robots to paint a picture? The concept may sound far-fetched, but a recent study in open-access journal Frontiers in Robotics and AI has shown that it is possible. The robots in question move about a canvas leaving color trails in their wake, and in a first for robot-created art, an artist can select areas of the canvas to be painted a certain color and the robot team will oblige in real time. The technique illustrates the potential of robotics in creating art, and could be an interesting tool for artists.
