Overweight children are less accurate in estimating their own body size. And the bigger their body is, the more inaccurate their guesses.

Solving the world’s food, feed and bioenergy challenges requires integration of multiple approaches and diverse skills. Andrea Eveland, Ph.D., assistant member at the Donald Danforth Plant Science Center, and her team identified a genetic mechanism that controls developmental traits related to grain production in cereals. The work was performed in Setaria viridis, an emerging model system for grasses that is closely related to economically important cereal crops and bioenergy feed stocks such as maize, sorghum, switchgrass and sugarcane.

For the first time, scientists have shown through direct satellite observations of the ozone hole that levels of ozone-destroying chlorine are declining, resulting in less ozone depletion.

We also need to share our data. So says world’s most prominent geoscientist, professor Markku Kulmala.

Environmental challenges, climate change, water and food security and urban air pollution, they are all interlinked, yet each is studied as such, separately. This is not a sustainable situation, for anybody anymore. To tackle this, professor Markku Kulmala calls for a continuous, comprehensive monitoring of interactions between the planet’s surface and atmosphere in his article “Build a global Earth observatory” published in Nature, January 4, 2018.

Twinkle, twinkle, little star, how I wonder what you are. Astronomers are hopeful that the powerful infrared capability of NASA’s James Webb Space Telescope will resolve a puzzle as fundamental as stargazing itself — what IS that dim light in the sky? Brown dwarfs muddy a clear distinction between stars and planets, throwing established understanding of those bodies, and theories of their formation, into question.
