Every year, the Breakthrough staff picks scientific developments likely to make news in the coming months. Here are four areas to keep an eye on in 2015. Arctic sea ice: As it disappears, the open ocean absorbs more energy, amplifying warming. Researchers are scrambling to figure out how that feedback affects weather thousands of miles away. Solar system encounters: NASA's Dawn spacecraft will arrive at the dwarf planet Ceres in the asteroid belt, and NASA's New Horizons mission will reach Pluto. LHC restart: The Large Hadron Collider at the CERN lab in Geneva will power up after 2 years of repairs. Now, with almost twice as much energy as before, the machine that bagged the Higgs boson will be hunting for new discoveries. Combined immunotherapy: Cancer treatments that work by boosting the immune system to fight tumors are a hot area of clinical research. Now, scientists are focusing on mixing and matching them—either with other novel immune therapies or with targeted drugs, radiation, or chemotherapy.
