Columbia Biomedical Engineering Professor Samuel Sia has taken his innovative lab-on-a-chip and developed a way to not only check a patient’s HIV status anywhere in the world with just a finger prick, but also synchronize the results automatically and instantaneously with central health-care records—10 times faster than the benchtop ELISA.
Columbia Engineering and Georgia Institute of Technology researchers have published a study in the Proceedings of the National Academy of Sciences showing that certain volatile organic gases can promote cloud formation in a way never considered before by atmospheric scientists. They say this is the first time gases have been shown to affect cloud formation in this way and will “improve our ability to model cloud formation, an important component of climate.”
A new Columbia Engineering study finds that the infant brain does not control its blood flow the same way as the adult brain, that the control of brain blood flow develops with age. These findings could change the way researchers study brain development in infants and children.
Columbia Engineering’s new “plug-and-play” method to assemble complex cell microenvironments is a scalable, highly precise way to fabricate tissues with any spatial organization or interest—like those found in the heart or skeleton or vasculature. The PNAS study reveals new ways to better mimic the enormous complexity of tissue development, regeneration, and disease.
Researchers at Columbia Engineering and Boston University have developed the first method to map evaporation globally using weather stations, which will help scientists evaluate water resource management, assess recent trends of evaporation throughout the globe, and validate surface hydrologic models in various conditions.
Columbia Engineering researchers have developed a new computational model that is highly predictive of breast cancer survival and, they hope, perhaps all cancers. Their work won the Sage Bionetworks/DREAM Breast Cancer Prognosis Challenge, a crowd-sourced effort for accurate breast cancer prognosis using molecular and clinical data.
Harish Krishnaswamy, assistant professor of electrical engineering at Columbia Engineering, has generated a record amount of power output—by a power of five—using silicon-based nanoscale CMOS (complementary metal oxide semiconductor) technology for millimeter-wave power amplifiers. Power amplifiers are used in communications and sensor systems to boost power levels for reliable transmission of signals over long distances as required by the given application. Krishnaswamy’s research will be reported at the June 2013 Institute of Electrical and Electronics Engineers Radio Frequency Integrated Circuits Symposium.
Researchers have directly observed—through moiré-patterned graphene—a rare quantum effect that produces a repeating butterfly-shaped energy spectrum, confirming the longstanding prediction of this quantum fractal energy structure called Hofstadter’s butterfly. The study is published in Nature’s May 15 Advance Online Publication.
Columbia University researchers have grown high-quality crystals of molybdenum disulfide, the world’s thinnest semiconductor, and studied how these crystals stitch together at the atomic scale to form continuous sheets, gaining key insights into the optical and electronic properties of this new “wonder” material.
Columbia Engineering researchers have used miniaturized electronics to measure the activity of individual ion-channel proteins with temporal resolution as fine as one microsecond, producing the fastest recordings of single ion channels ever performed.
