Fossil pollen holds clues to past

By Mackenzie Myers What if, instead of ancient treasure and tombs, Indiana Jones researched ancient pollen and soil?  Beyond just a seasonal nuisance or a crucial component of agriculture, pollen can be a key to understanding the past. It clues researchers in to how land was used thousands of years ago, as well as what the climate conditions were like at that time. And according to a new study from North Carolina State University, this tool may be available in more areas than previously thought.  Painting the past with fossil…

Anthropocene mass extinction: are we there yet?

By Jacqueline Mattos In the last few decades, scientific observations have highlighted that we are now facing a mass extinction, caused in major part by human activity: habitat fragmentation, invasive species, spread of pathogens and diseases, climate changes leading to global warming, and, of course, direct killing of endangered species. However, this is still a debated topic among scientists. Some say that we are not in a mass extinction event, and that if we were, conservation biology and all the efforts we have been putting into conserving animal species would…

Could Agriculture Save US Water Supply?

Population growth and climate change are making water an even more scarce resource. Does agriculture have the power to reduce water shortages? By Mackenzie Myers This article is part of a series about key science policy issues. Please use these articles to become an informed voter, ask political candidates about the issues, and put every candidate on record about science. This time of year in California’s Central Valley, it’s easy to see where the Golden State gets its nickname. Golden sun shines on golden grasses of rolling golden hills, parched…

Mapping the Urban Heat Island Effect with Wicked Hot Boston

by Emily Hostetler, Sara Benson, and Roxanne Lee It’s not just in your head; Boston really is hotter in the summer. When urban areas are warmer than surrounding non-urban environments, we experience a phenomenon called the urban heat island (UHI) effect.  Cities are filled with large amounts of artificial materials, such as concrete and asphalt, that absorb heat throughout the day and release heat at night. Living materials like trees, flowers, and grass tend to make areas feel cooler due to the shade they create and the water they release…

Help Audubon Protect Threatened Birds

Audubon’s Climate Watch Program needs volunteers to help it spot 12 birds threatened by climate change. Are you in? “Hope is the thing with feathers/ That perches in the soul,” Emily Dickinson wrote. Is there hope for our feathered friends in the era of climate change? Yes, but they need our help. More than 300 North American birds will likely lose over 50 percent of their current geographical range by 2080, according to Audubon’s 2014 Birds and Climate Change Report. This means that the areas with the climate conditions these…

Book Review: World Without Fish

By Patricia Balbon Day-to-day encounters of fish—at the grocery store, visiting an aquarium—passively reinforce a notion of triviality about aquatic life until we are prompted to take a pause and spare a thought for a breathtaking world beyond the shore. This month’s selection in our ongoing book review series, World Without Fish, prompts such reflection; however, as the pages turn, we witness the marine world’s vulnerability alongside its majesty.  Through Mark Kurlansky’s words and Frank Stockton’s art, we are challenged by the crisis of disappearing biodiversity in our oceans.  This…
