Please use these articles to become an informed voter, ask political candidates about the issues, and put every candidate on record about science. Countries around the world, both developed and developing, have been grappling with growing piles of plastic waste from overuse of packaging materials, such as those for food and beverages, and single-use plastic tableware. In 2015, 42 percent of all plastic produced was used for packaging, much of which is used only…
Read MoreBy Jacqueline Mattos (@mattosjacq) Microplastics are tiny pieces of plastic that pollute the environment and can range from 0.05 to 5 millimeters in length. Bigger plastic items can be fragmented by the action of light, temperature fluctuations, ocean waves, or mechanical abrasion into smaller pieces that are widely dispersed, persistent in the environment, and sometimes accompanied by microorganisms. A recent article by Bergmann et al., published in the periodical Science Advances, assessed quantities of microplastics in the snow from the Alps and other northern European sites to the Arctic and…

Read MoreBy Nicholas Dove (@nicholascdove), for The Biota Project How do people live with the threat of wildfires, and what can be done to protect lives? That’s a question on a lot of people’s minds as wildfires get worse and worse each year. If you haven’t already, check out last month’s post by the Biota Project featuring Erin Dickman to learn about how she was evacuated from the Ferguson Fire. This month, however, we try to understand how people live with this risk. Fires Have Become More Severe Before we go…
Read MoreBy Shayna Keyles (@shaynakeyles) How do plants know which way is up and which way is down? No matter which way you put a seed in the soil, it will always send its roots down and its shoots up. (Unless you’re in space–we’ll get back to that later.) [tweetthis]Plants can sense light, gravity, and water. So no matter where they are, they can figure out up and down.[/tweetthis] The answer lies in tropism: motion in response to external stimulus. This is pretty amazing, considering that in the traditional sense, plants can’t…
Read MoreBy Neha Jain @lifesciexplore Whenever you eat fruits, vegetables, and nuts, take a moment to thank honeybees for their pollination services that contribute $17 billion to the US economy each year. In fact, almonds are almost solely dependent on honeybees for pollination. Populations of these much-needed pollinators have mysteriously plunged over the past decade, and many studies suggest a link to the use of neonicotinoid insecticides among other factors such as climate change and disease. Recently, scientists found that honeybees prefer sugar water laced with the fungicide chlorothalonil and the…
