A study led by Rafael Yuste, a neuroscientist, shows how an algorithm for filtering spam can learn to pick out, from hours of video footage, the full behavioral repertoire of tiny, pond-dwelling Hydra. Read More

Columbia Engineers discover geometric underpinnings of T-cell stimulation through precise engineering of T-cell receptor geometry, building a 3D nanofabricated biomimetic surface that simulates the key components of an antigen-presenting cell. Read More

An international collaboration will study the wasting of the Thwaites glacier, which already accounts for around 4 percent of current global sea-level rise, and could collapse within decades or centuries. Read More

A new study co-authored by Columbia scientist Francesco Muschitiello suggests we may be underestimating the chances of extreme heat and droughts in Europe under climate change. Read More

Using the photo-sharing site Instagram as a test case, Columbia researchers found that recommendation algorithms influence social status by amplifying network disparities. Read More

Coastal waters play an important role in the carbon cycle by absorbing carbon into sediments or transferring it to the open ocean, a new study co-authored by Columbia geochemist Wade McGillis confirms. Read More

Two new Columbia papers find that the line that divides the moist East and arid West is edging eastward due to climate change—and the implications for farming and other pursuits could be huge. Read More
