New sunspots potentially herald increased solar activity
On May 29, 2020, a family of sunspots -- dark spots that freckle the face of the Sun, representing areas of complex magnetic fields -- sported the biggest solar flare since October 2017. Although the sunspots are not yet visible (they will soon rotate into view over the left limb of the Sun), NASA spacecraft spotted the flares high above them.

Integrating satellite and socioeconomic data to improve climate change policy
Bangladesh is on track to lose all of its forestland in the next 35-40 years, leading to a rise in CO2 emissions and subsequent climate change, researchers said. However, that is just one of the significant land-use changes that the country is experiencing. A new study uses satellite and census data to quantify and unravel how physical and economic factors drive land-use changes. Understanding this relationship can inform climate policy at the national scale in Bangladesh and beyond.

New view on how tissues flow in the embryo
Watching and measuring what happens in tissues inside the human embryo is currently not possible, and it's difficult to do in mammalian models. Because humans and the fruit fly Drosophila share so many biological similarities, researchers tackled this problem by focusing on fruit flies. The team reports today that they can predict when the tissue will begin to rapidly flow just by looking at cell shapes in the tissue.

Study charts developmental map of inner ear sound sensor in mice
A team of researchers has generated a developmental map of a key sound-sensing structure in the mouse inner ear. Scientists analyzed data from 30,000 cells from mouse cochlea, the snail-shaped structure of the inner ear. The results provide insights into the genetic programs that drive the formation of cells important for detecting sounds and the underlying causes for some forms of inner ear hearing loss.
