Description: Hi there – I’m Larissa Branin, host of Science Today and it’s that time of the week again where we go over some of the stories covered this past week. First, we learned that by the end of the century climate change will likely cause a decline in wheat and barley yields by up to 33 percent. This statistical model was developed by a team of researchers led by UC Davis. Graduate student Matthew Gammans, who worked on the study, told us it was based on 65 years of weather records and data from wheat and barley yields in France.  “So we started by looking at the relationship between weather and yields and then using some climate change projections, we forecasted that relationship into the future to see what we can expect to happen to these yields.” Their work is one of the first flexible statistical models applied to these cereal crops, which means that every potential temperature was included in the analysis. We then chatted with public health professor Kristine Madsen of UC Berkeley about soda consumption in the U.S. falling to a 31-year low last year. Instead, consumers seem to be reaching for lower-calorie produces, including bottled water. Madsen had found similar findings in Berkeley, California after the city passed the nation’s first soda tax back in 2014. “Even in the comparison cities of Oakland and San Francisco, there was an overall increase of 20 percent in water consumption. But it was 63 percent in Berkeley. So, it looks like people were switching from sugar-sweetened beverages to really what I would say is the healthiest alternative.” Speaking of healthy alternatives, there’s even more reason to never start smoking. We learned that even if parents quit before conception, their prior smoking habit may still put their child’s health at risk. UC San Francisco researcher Adam de Smith studied dust in homes where children were diagnosed with leukemia and found an increased level of tobacco particles in the carpeting. “If a family is smoking relatively heavily, they might not even be smoking in the house, they might be smoking outside, but when they come into the home, particles drop onto the carpet. If they have children several years later, we have found that those particles can remain there several years later. So it is possible if a child is playing around on the carpet, he may still be exposed to toxic particles that could perhaps increase the leukemia risk.” And even frequently vacuuming does not eliminate all the dust. So again – all the more reason to never pick up the habit. Well, that’s all for now.
