A new study by Columbia Engineering researchers finds that the infant brain does not control its blood flow in the same way as the adult brain.

Researchers at Columbia Engineering and Georgia Institute of Technology have published a study in the February 4 online Early Edition of Proceedings of the National Academy of Sciences (PNAS) showing—for the first time—that certain volatile organic gases can promote cloud formatio

Klaus Lackner’s approach to slowing global warming is to clean up the atmosphere—literally.

The word “nanos” is Greek for dwarf, and over time “nano” has come to refer to anything small, like the iPod nano. In science, however, it has a very precise definition: 10-9, or a billionth.

A digital microarray from the lab of Ken Shepard, a professor of electrical engineering, can measure individual DNA molecules, which are shown in this image. The new technology dramatically improves and simplifies genetic analysis.

Ken Shepard, a professor of electrical engineering, believes there is nowhere else in the world where he could do what he does. “Imagine a convergence of semiconductor technology and biotechnology. There is no company out there that has expertise in both,” he says.

It’s relatively simple to build a device capable of detecting wireless signals if you don’t mind making one that consumes lots of power. It’s not so easy to design energy-efficient devices that function as well as the components they replace, or to do it at the nano scale.

Jim Yardley has seen firsthand how the nanotechnology field has exploded over the past decade. “It’s extremely exciting,” says the managing director of Columbia’s Nanoscale Science and Engineering Center.

Parallel application profiles, such as the ones above, indicate that applications do not consume energy uniformly, motivating the fine-grained energy management techniques to be developed as part of the CAREER project.

Computer Science Assistant Professor Martha Kim has won a National Science Foundation (NSF) CAREER award to develop energy tracking and monitoring techniques to audit and control software energy consumption.

Dillon Liu, SEAS ’13, just found out that not only has he won a prestigious Marshall Scholarship—he is also the first Columbia Engineering student ever to receive one.
