In a discovery that could have profound implications for future energy policy, Columbia scientists have demonstrated it is possible to manufacture solar cells that are far more efficient than existing silicon energy cells by using a new kind of material, a development that could help redu

Five Columbia faculty members have been named fellows of the American Association for the Advancement of Science, the world’s largest general scientific society.

Three Columbia professors were among the 78 recipients of awards in the National Institutes of Health High Risk-High Reward program.

In the search to understand memory, Wei Min is looking at cells at the most basic level, long before the formation of neurons and synapses. The assistant professor of chemistry studies the synthesis of proteins, the building blocks of the body formed using genetic code from DNA.

When he received his A.B. from Harvard in 1969, Martin Chalfie wasn’t sure what he would do next. His worst grades had been in physics and chemistry, and a summer research project had failed, so science seemed out of reach.

When Koji Nakanishi retired six years ago, the chemistry department threw a party for him, complete with a cake that said, “Happy Retirement, Koji. See you tomorrow!” Sure enough, he was back in his Chandler Hall office the next day, where he continues to work six days a week.

Suppose you’re in an elevator standing next to someone with a million dollars in grant money to fund your research, if only you can convince her in the brief span of an elevator ride. You’re in need of the proverbial elevator pitch.

Solomon led efforts to identify the cause of the ozone hole over Antarctica.

An American atmospheric chemist who led efforts to identify the cause of the Antarctic ozone hole and a French geochemist who extracted the longest-yet climate record from polar ice cores have won the prestigious 2012 Vetlesen Prize.

Nicholas (Nick) Turro, chair of Chemistry and co-chair of Chemical Engineering departments, passed away Nov. 24. He was 74.

Researchers in the group of Centennial Professor of Chemistry, Samuel Danishefsky, have synthesized what is arguably the largest and most complex biological molecule ever assembled by the methods of organic chemistry.
