Google helped make an exquisitely detailed map of a tiny piece of the human brain
The news: A team led by scientists from Harvard and Google has created a 3D, nanoscale-resolution map of a single cubic millimeter of the human brain. Although the map covers just a fraction of the organ, it is currently the highest-resolution picture of the human brain ever created.
How they did it: To make a map this finely detailed, the team had to cut the tissue sample into 5,000 slices and scan them with a high-speed electron microscope. Then they used a machine-learning model to help electronically stitch the slices back together and label the features.
Why it matters: Many other brain atlases exist, but most provide much lower-resolution data. At the nanoscale, researchers can trace the brain’s wiring one neuron at a time to the synapses, the places where they connect. And scientists hope it could help them to really understand how the human brain works, processes information, and stores memories. Read the full story.

Hong Kong is targeting Western Big Tech companies in its ban of a popular protest song
It wasn’t exactly surprising when on Wednesday, May 8, a Hong Kong appeals court sided with the city government to take down “Glory to Hong Kong” from the internet.
The trial, in which no one represented the defense, was the culmination of a years-long battle over a song that has become the unofficial anthem for protesters fighting China’s tightening control and police brutality in the city.
It remains an open question how exactly Big Tech will respond. But the ruling is already having an effect beyond Hong Kong’s borders: just hours afterwards, videos of the anthem started to disappear from YouTube. Read the full story.

The big story
How tracking animal movement may save the planet
Animals have long been able to offer unique insights about the natural world around us, acting as organic sensors picking up phenomena invisible to humans. Canaries warned of looming catastrophe in coal mines until the 1980s, for example.
These days, we have more insight into animal behavior than ever before thanks to technologies like sensor tags. But the data we gather from these animals still adds up to only a relatively narrow slice of the whole picture.
This is beginning to change. Researchers are asking: What will we find if we follow even the smallest animals? What could we learn from a system of animal movement, continuously monitoring how creatures big and small adapt to the world around us? It may be, some researchers believe, a vital tool in the effort to save our increasingly crisis-plagued planet. Read the full story.
