On their most recent trip to study seeps, Indiana State University scientists made a big discovery regarding a tiny creature that lives in both seep and non-seep habitats.

Rock soil droplets formed by heating most likely came from Stone Age house fires and not from a disastrous cosmic impact 12,900 years ago, according to new research from the University of California, Davis. The study, of soil from Syria, is the latest to discredit the controversial theory that a cosmic impact triggered the Younger Dryas cold period.

From new insights into the building blocks of matter to advances in understanding batteries, superconductors, and a protein that could help fight cancer, 2014 was a year of stunning successes for the U.S. Department of Energy's Brookhaven National Laboratory. Oh, and did we mention the opening of a brand new facility that will push the limits of discovery across the scientific spectrum? For details on these and the rest of our Top-10 breakthroughs, check out the items below. You can follow Brookhaven Lab on Facebook, Twitter, and Tumblr to learn about the discoveries of 2015 as they happen.

Crowd science is making possible research projects that might otherwise be out of reach, tapping thousands of volunteers to help with such tasks as classifying animal photos, studying astronomical images, counting sea stars and examining cancer cell images. Also known as “citizen science,” these efforts to involve ordinary people in research projects have attracted interest from policy makers, scientific agencies and others.

Unlike other drug addictions, there are no pharmacological treatments for cocaine dependence. According to Arizona State University School of Life Sciences professor Janet Neisewander, it’s because cocaine addiction is tricky.

The southeastern United States is a natural laboratory for scientists studying how chemicals emitted by human activities and trees interact with each other and affect air quality and climate. A new study has found that certain emissions from cars and coal-fired power plants promote processes that transform naturally occurring emissions from trees into organic aerosols. Organic aerosols make up a substantial fraction of ambient particulate matter (PM) that can affect climate, air quality and human health.
