UW researcher predicts population increase

The global population is on the rise. Using new statistical models, never before applied to population estimates, statisticians have determined global population could be 11 billion people by 2100, 2 billion more than previously predicted. 

The figure comes from a new Bayesian statistical model, which uses the most recent data on population, fertility, and mortality, and also allows researchers to incorporate past experience in future projections.

An unlikely source affecting ocean chemistry 

The migration of tiny zooplankton and crustaceans like krill has a great effect on ocean chemistry, according to new research from the UW.

During these large migrations, urine is secreted. The ammonia in the urine plays a significant role in some regions of the ocean that aren’t as oxygenated.

Songbird singing reveals cell growth 

During the breeding season, songbirds sing the melodies they do because their specialized brain cells are multiplying. A new UW study sheds light on this ornithological phenomenon, which may in turn provide insight into cell replacement in humans.

Spermtastic swimming 

“For a long time most people thought the sperm played a relatively passive role, but our findings suggest that sperm may have a number of tactics that allow them to bypass or avoid the snares that the female reproductive tract lays out for them,” said Donner Babcock, the study’s lead author and a UW professor of physiology and biophysics, in a UW Health Sciences NewsBeat press release.

More effective treatment for disadvantaged women

It is common knowledge that underprivileged women face many obstacles in receiving accessible, affordable, and acceptable care for depression. 

“An unhelpful belief out there is that because they have so many financial, social, and medical problems, there is nothing that we can do to help with their depression,” said Evette Ludman, professor at the UW department of psychiatry and behavioral sciences, in an email.
