Dinosaurs — the one scientific topic popular to both liberals and conservatives
Research shows the groups have different tastes when buying science books. For the most part.
While scientists generally try to stay out politics, letting evidence-based research to speak for itself, the strong division in American society has spread to science. How you view stem cell research, climate change, evolution and the role of science in setting public policy is one indicator of political leanings. Another can be the kind of science books you read with a new study finding that liberals and conservatives have very different tastes.
By analyzing millions of online purchases, researchers from Cornell, Yale and University of Chicago found that there are clear partisan preferences in how we buy books on scientific topics. Liberals opt for so-called "basic" sciences, like physics, astronomy and zoology, while conservatives go for applied and commercial sciences, such as medicine, criminology and geophysics.
"When we look at what science books they read and on what topics, liberals and conservatives are noticeably divided," said the study's co-author Professor Michael Macy from Cornell University. “They tend to not read the same books, and they don't follow the same topics."
Feng Shi, the study's first author, proposed that liberals like “scientific puzzles" while conservatives prefer “problem-solving".
One topic popular with both sides — books on dinosaurs. These were bought across the whole political spectrum.
For the study, researchers looked at purchase histories from Amazon and Barnes & Noble online stores, creating a dataset of 25 million “co-purchases" and 1.5 million books. They relied on the fact that these retailers recommend books to customers via book suggestion features like “Customers Who Bought This Item Also Bought". That way the scientists could see what scientific texts were bought by those who also got liberal or conservative books.
The study's authors think it's likely that people who buy political books get science books to support their views rather than out of a general interest in science.
Is there a way science could help heal the division in the country? The study's lead author Professor James Evans from University of Chicago is somewhat optimistic, thinking that people on all sides ultimately respect science.
"Interest and respect for science remains high across political boundaries in the United States, suggesting that it could be a crucial bridge for crossing partisan divides in America," said Professor Evans.
Professor Macy thinks their research highlights the fact that science communication needs to improve.
"Our findings point to the need to communicate scientific consensus when it occurs, helping scientists find common cause with their audiences and adding public debate alongside scientific analysis to clarify the distinction between facts and values," said Macy.
While the study is illuminating, it has some limitations, with political scientist Toby Bolsen cautioning that this research did not draw on a random sample of books, relying instead on how the online sellers categorized them. We also don't know conclusively the motivations behind why individuals bought certain books.

What can 3D printing do for medicine? The "sky is the limit," says Northwell Health researcher Dr. Todd Goldstein.
- Medical professionals are currently using 3D printers to create prosthetics and patient-specific organ models that doctors can use to prepare for surgery.
- Eventually, scientists hope to print patient-specific organs that can be transplanted safely into the human body.
- Northwell Health, New York State's largest health care provider, is pioneering 3D printing in medicine in three key ways.
Three academic papers from Australia shows sizable bone spurs growing at the base of our skulls.
- A team of researchers in Queensland says 33% of the Australian population has sizable bone spurs growing at the base of their skulls.
- This postural deformity, enthesophytes, results in chronic headaches and upper back and neck pain.
- The likelihood humans will alter their addiction to this technology is low, so this might be a major consequence of technology.
They'll reportedly last for thousands of years. This technology may someday power spacecraft, satellites, high-flying drones, and pacemakers.
Nuclear energy is carbon free, which makes it an attractive and practical alternative to fossil fuels, as it doesn't contribute to global warming. We also have the infrastructure for it already in place. It's nuclear waste that makes fission bad for the environment. And it lasts for so long, some isotopes for thousands of years. Nuclear fuel is comprised of ceramic pellets of uranium-235 placed within metal rods. After fission takes place, two radioactive isotopes are left over: cesium-137 and strontium-90.
Facebook was careful to say that Libra is not maintained internally and is instead serviced by a non-profit collective of companies.
- Facebook has just announced its new cryptocurrency, Libra.
- Early investors include many of the world's leading companies, implying they will accept Libra as payment
- The announcement was met with a mixed response, but only time will tell how Libra will be received
