Harvard University is a private Ivy League research university in Cambridge, Massachusetts, with about 6,700 undergraduate students and about 13,100 postgraduate students. Established in 1636 and named for its first benefactor, clergyman John Harvard, Harvard is the United States' oldest institution of higher learning. Its history, influence, wealth, and academic reputation have made it one of the most prestigious universities in the world. The university is organized into eleven principal academic units—ten faculties and the Radcliffe Institute for Advanced Study—with campuses throughout the Boston metropolitan area: its 209-acre (85 ha) main campus is centered on Harvard Yard in Cambridge, approximately 3 miles (5 km) northwest of Boston; the business school and athletics facilities, including Harvard Stadium, are located across the Charles River in the Allston neighborhood of Boston; and the medical, dental, and public health schools are in the Longwood Medical Area. Harvard's endowment is worth $40.9 billion, making it the largest of any academic institution. Harvard is a large, highly residential research university. The nominal cost of attendance is high, but the university's large endowment allows it to offer generous financial aid packages. The Harvard Library is the world's largest academic and private library system, comprising 79 individual libraries holding over 18 million items.

Programming pH

“pH — the concentration of protons in a watery solution — indicates how acidic the solution is. It regulates a broad range of natural and engineered chemical processes, including the synthesis of designed DNA sequences for applications in biotechnology. Changing the pH …

Complex motions for simple actuators

“Inflatable actuators use origami principles to deform in intricate ways. Inflatable soft actuators that can change shape with a simple increase in pressure can be powerful, lightweight, and flexible components for soft robotic systems. But there’s a problem: These …

Tuning sound waves on chip

“Researchers control and modulate acoustic waves on chip for the first time. Acoustic waves are slower than electromagnetic waves of the same frequency but, even in the high-speed world of computing and communications, that’s not a bad thing. Short …

Research extends the lifetime of molecules in organic flow batteries to practical values

“Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS), in collaboration with colleagues at the University of Cambridge, have developed a new method to dramatically extend the lifetime of organic aqueous flow batteries, improving the …

High-speed, efficient and compact electro-optic modulators for free space

“New photonic devices may have applications in lidar, optical computing and more Electro-optic modulators, which control aspects of light in response to electrical signals, are essential for everything from sensing to metrology and telecommunications. Today, most research into these modulators …

Diamond mirrors for high-powered lasers

“Just about every car, train and plane that’s been built since 1970 has been manufactured using high-power lasers that shoot a continuous beam of light. These lasers are strong enough to cut steel, precise enough to perform surgery, and …

Self-propelled, endlessly programmable artificial cilia

“For years, scientists have been attempting to engineer tiny, artificial cilia for miniature robotic systems that can perform complex motions, including bending, twisting, and reversing. Building these smaller-than-a-human-hair microstructures typically requires multi-step fabrication processes and varying stimuli to create the …

In Einstein’s footsteps and beyond

“Zero-index metamaterials offers new insights into the foundations of quantum mechanics In physics, as in life, it’s always good to look at things from different perspectives. Since the beginning of quantum physics, how light moves and interacts with matter …

Making 3D printing truly 3D

“Researchers from Rowland Institute eliminate need for 2D layering Don’t be fooled by the name. While 3D printers do print tangible objects (and quite well), how they do the job doesn’t actually happen in 3D, but rather in …

First integrated laser on lithium niobate chip

“Research paves the way for high-powered telecommunication systems For all the recent advances in integrated lithium niobate photonic circuits — from frequency combs to frequency converters and modulators — one big component has remained frustratingly difficult to integrate: lasers. Long haul telecommunication …
