Tall Women More Likely to Have Twins

LiveScience reports on a study that shows a link between the height of mothers and the likelihood that they will have twins. The study compared the heights of 149 mothers of twins or triplets to those of average U.S. women and found that the moms of twins and triplets were on average more than an inch taller.

Dr. Gary Steinman, who led the study, explained that taller women have more insulin-like growth factor.

Insulin-like growth factor (IGF) is a protein released by the liver in response to growth hormones. It increases the sensitivity of the ovaries to follicle stimulating hormone, thereby increasing ovulation.

It's this increased sensitivity that influences the rate of twinning. I also found it interesting that countries with higher average heights have higher rates of twinning.

New AI-Driven Music System Analyzes Tracks for Perfect Playlists

Whether you're planning a bachelorette party or recovering from a breakup, a well-curated playlist makes all the difference. If you don't have time to pick the perfect songs manually, services that use the AI-driven system Sonic Style may be able to figure out exactly what you have in mind based on your request.

According to Fast Company, Sonic Style is the new music-categorizing service from the media and entertainment data provider Gracenote. There are plenty of music algorithms out there already, but Sonic Style works a little differently. Rather than listing the entire discography of a certain artist under a single genre, the AI analyzes individual tracks. It considers factors like the artist's typical genre and the era the song was recorded in, as well as qualities it can only learn through listening, like tempo and mood. Based on nearly 450 descriptors, it creates a super-accurate "style profile" of the track that makes it easier for listeners to find it when searching for the perfect song to fit an occasion.

Playlists that use data from Sonic Style feel like they were made by a person with a deep knowledge of music rather than a machine. That's thanks to the system's advanced neural network. It also recognizes artists that don't fit neatly into one genre, or that have evolved into a completely different music style over their careers. Any service—including music-streaming platforms and voice-activated assistants—that uses Gracenote's data will be able to take advantage of the new technology.

With AI at your disposal, all you have to do as the listener is decide on a style of music. Here are some ideas to get you started if you want a playlist for productivity.
