The FBI, National Institutes of Health (NIH), and other agencies who oversee federal research grants are currently asking if the open culture of science in the U.S. is inviting other countries to steal it.

The FBI has been warning since 2016 that researchers could be potentially sending confidential research, and even biological samples, to other countries. On Monday, a report in the New York Times outlined the scale of ongoing investigations: nearly 200 cases of potential intellectual property theft at 71 different institutions. 

New York Times health and science reporter Gina Kolata, who broke the story, explains the investigations, and why China is featuring so prominently.

Then, on May 29, 1919, Sir Arthur Eddington and his scientific team photographed the stars during a total solar eclipse. The resulting images displayed stars that seemed slightly out of place—an indication that the mass of the sun had caused starlight to veer off course, as Einstein’s general theory of relativity had predicted. Six months later, on November 6, 1919, Eddington’s team presented their findings before a joint meeting of the Royal Society and the Royal Astronomical Society—and skyrocketed Einstein to worldwide fame. 

Science writer Ron Cowen, author of Gravity’s Century: From Einstein’s Eclipse to Images of Black Holes, joins Ira to tell the story.

Watch the Mercury transit! On Monday, November 11th, Mercury will slice a path across the sun—an occurrence that happens only about 13 times a century. These days, it’s fairly easy to observe a transit of Mercury—many local observatories or science centers hold viewing parties. But several centuries ago, transit chasers sailed the globe to observe these relatively rare events, in an effort to use them to calculate the size of the solar system. Find out how you can view the transit.

Researchers are collecting snapshots of Acadia National Park to supplement satellite data on fall leaf colors. Listen and learn more about this citizen science project. 

And, the Trump administration has begun a year-long process to exit the agreement—which would complete the day after the next presidential election. Listen to this week's science news roundup.
