SEAS researchers Peter Huybers and Cristian Proistosescu resolved a major conflict in estimates of how much the Earth will warm in response to a doubling of carbon dioxide in the atmosphere. Read the full story hereBy Harvard John A. Paulson School of Engineering and Applied Sciences

Michael McElroy, Gilbert Butler Professor of Environmental Studies at the Harvard John A. Paulson School of Engineering and Applied Sciences, argues that the United States must move towards a zero-carbon future, replacing its reliance on fossil fuels with a combination of wind, solar, hydroelectric and nuclear power. Such a transition would not onl…

Applied physicist Hechen Ren joins the podcast to discuss the title of her paper,"Controlled Finite Momentum Pairing and Spatially Varying Order Parameter in Proximitized HgTe Quantum Wells." It gets spooky. Read more about this episode's research on our website.By Harvard John A. Paulson School of Engineering and Applied Sciences

Artificial intelligence has already transformed our lives — from the autonomous cars on the roads to the robotic vacuums and smart thermostats in our homes. Over the next 15 years, AI technologies will continue to make inroads in nearly every aspect of our lives, from education to entertainment, healthcare to security. The question is, are we ready…

Soft robots do a lot of things well but they’re not exactly known for their speed. The artificial muscles that move soft robots, called actuators, tend to rely on hydraulics or pneumatics, which are slow to respond and difficult to store. Dielectric elastomers could offer an alternative to pneumatic actuators but they currently require complex and …

Earlier this year, in an experiment about five-feet long, Harvard University researchers say they observed evidence of the abrupt transition of hydrogen from liquid insulator to liquid metal. It is one of the first times such a transition has ever been observed in any experiment. Read the full story here.…

Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences, the University of California Santa Barbara, and Washington University in St. Louis have shown for the first time how neurons in the SCN are connected to each other, shedding light on this vital area of the brain. Understanding this structure — and how it respon…

Curved lenses, like those in cameras or telescopes, are stacked in order to reduce distortions and resolve a clear image — that's why telephoto lenses are so long and high-powered microscopes so big. But what if you could replace those stacks with a single flat — or planar — lens? Researchers from the Harvard John A. Paulson School of Engineering a…

A very small hologram that can be used across all different wavelengths of light and can be programmed with different images based on the direction of light that works because it's made from a material that doesn't absorb certain light and has other properties not found in nature.By Harvard John A.
