The role of technology in the Arab Spring and the Boston bombings, repression in North Korea, and privacy in the Internet age were just some of the topics Eric Schmidt, executive chairman and former CEO of Google, and Jared Cohen, director of Google’s in-house think tank, Google Ideas, discussed when they spoke at Columbia Journalism School on April 30.

Ronald O. Perelman, Chairman and CEO of MacAndrews & Forbes Holdings Inc. and a member of the School’s Board of Overseers, has pledged a landmark gift of $100 million to Columbia Business School. It joins Class of 1969 alumnus Henry R. Kravis’s $100 million contribution as the largest in the School’s history.

Civil Engineering and Engineering Mechanics Professor Patricia J. Culligan and her doctoral student, Robert Elliott, were part of an interdisciplinary team that included members of the Aquanauts student group at Columbia University whose design proposal was recognized for innovative technology in a green roof competition sponsored by the U.S. Environmental Protection Agency (EPA).

Mark Cane, an expert on the El Niño climate pattern, and Terry Plank, an authority on explosive volcanoes—both scientists at Columbia University’s Lamont-Doherty Earth Observatory--have been elected to the National Academy of Sciences. Membership in the National Academy, given for excellence in original scientific work, is one of the highest honors awarded to engineers and scientists in the United States.

Extreme weather can wreak havoc on cities and their economies. Damage from hurricanes Katrina and Sandy is estimated at more than $150 billion and over $60 billion, respectively. Weather-based power failures and disruptions to transportation systems can delay commuters, stall deliveries, and choke supply chains. And even where extreme conditions are common, economic life suffers. Regions with hot, wet climates are less productive on average.

“Global mapping of cancer gene expression changes to the human metabolic network; increased enzymatic expression across tumors is shown in red and decreased in blue,” said Dr. Vitkup (who provided the image).

A massive study analyzing gene expression data from 22 tumor types has identified multiple metabolic expression changes associated with cancer. The analysis, conducted by researchers at Columbia University Medical Center, also identified hundreds of potential drug targets that could cut off a tumor’s fuel supply or interfere with its ability to synthesize essential building blocks. The study was published today in the online edition of Nature Biotechnology.

The Lamont-Doherty Core Repository holds one of the world’s most unique and important collections of scientific samples from the deep sea—approximately 72,000 meters of sediment cores from every major ocean and sea. It is both an archive of sediment (some terrestrial), rocks and coral from beneath the ocean floor, and an archive of the digital data pertaining to the material. Collecting a core a day, Lamont scientists catalogue materials as much as 100 million years old.

This exhibit at Maison Française and The Italian Academy for Advanced Studies at Columbia University, open until May 4, features seventy works of visual arts (paintings, drawings, photographs) about the Cambodian genocide under the Khmer Rouge, made by the great contemporary artists Vann Nath and Séra (both survivors of the genocide), as well as works by emerging artists who were invited to create artworks evoking the genocide during three "memory workshops" held at Bophana Center between 200
