Researchers develop technique to control and measure electron spin voltage

(Harvard John A. Paulson School of Engineering and Applied Sciences) Information technologies of the future will likely use electron spin -- rather than electron charge -- to carry information. But first, scientists need to better understand how to control spin and learn to build the spin equivalent of electronic components and tools. Show More Summary

Reconciling predictions of climate change

(Harvard John A. Paulson School of Engineering and Applied Sciences) Harvard researchers have resolved a major conflict in estimates of how much the Earth will warm in response to a doubling of CO2 in the atmosphere -- finding that the...Show More Summary

How eggs got their shapes

(Harvard John A. Paulson School of Engineering and Applied Sciences) The evolution of the amniotic egg -- complete with membrane and shell -- was key to vertebrates leaving the oceans and colonizing the land and air but how bird eggs evolved into so many different shapes and sizes has long been a mystery.

Learning about nutrition from 'food porn' and online quizzes

(Harvard John A. Paulson School of Engineering and Applied Sciences) Harvard and Columbia researchers designed an online experiment to test how people learn about nutrition in the context of a social, online quiz.

First flat lens for immersion microscope provides alternative to centuries-old technique

(Harvard John A. Paulson School of Engineering and Applied Sciences) A team of researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) has developed the first flat lens for immersion microscopy....Show More Summary

Immersion meta-lenses at visible wavelengths for nanoscale imaging

A team of researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) has developed the first flat lens for immersion microscopy. This lens, which can be designed for any liquid, may provide a cost-effective and easy-to-manufacture alternative to the expensive, centuries-old technique of hand polishing lenses for immersion objectives.

The science behind making the perfect pitch

(Harvard John A. Paulson School of Engineering and Applied Sciences) Applied mathematicians at the Harvard SEAS used mathematical models to figure out the best strategies to throw something at a target. The team found that while underhand...Show More Summary

Technique makes more efficient, independent holograms

Not far from where Edwin Land—the inventor of the Polaroid camera—made his pioneering discoveries about polarized light, researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) are continuing to unlock the power of polarization.

Technique makes more efficient, independent holograms

(Harvard John A. Paulson School of Engineering and Applied Sciences) Recently, a team of researchers encoded multiple holographic images in a metasurface that can be unlocked separately with differently polarized light.

Sculpting optical microstructures with slight changes in chemistry

(Harvard John A. Paulson School of Engineering and Applied Sciences) In 2013, materials scientists at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and the Wyss Institute of Biologically Inspired Engineering, grew a garden of self-assembled crystal microstructures. Show More Summary

Sculpting optical microstructures with slight changes in chemistry

In 2013, materials scientists at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and the Wyss Institute of Biologically Inspired Engineering, grew a garden of self-assembled crystal microstructures. Now, applied mathematicians at SEAS and Wyss have developed a framework to better understand and control the fabrication of these microstructures.

Solving the mystery of the Arctic's green ice

(Harvard John A. Paulson School of Engineering and Applied Sciences) In 2011, researchers observed something that should be impossible -- a massive bloom of phytoplankton growing under Arctic sea ice in conditions that should have been far too dark for anything requiring photosynthesis to survive. Show More Summary

Night lights, big data

(Harvard John A. Paulson School of Engineering and Applied Sciences) Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and the Environmental Defense Fund (EDF) have developed an online tool that incorporates 21 years of night-time lights data to understand and compare changes in human activities in countries around the world.

A stem's 'sense of self' contributes to shape

(Harvard John A. Paulson School of Engineering and Applied Sciences) It is well known that as plants grow, their stems and shoots respond to outside signals like light and gravity. But if plants all have similar stimuli, why are there...Show More Summary

Laser activated gold pyramids could deliver drugs, DNA into cells without harm

(Harvard John A. Paulson School of Engineering and Applied Sciences) The ability to deliver cargo like drugs or DNA into cells is essential for biological research and disease therapy but cell membranes are very good at defending their territory. Show More Summary

A perfect storm of fire and ice may have led to snowball Earth

(Harvard John A. Paulson School of Engineering and Applied Sciences) What caused the largest glaciation event in Earth's history, known as 'snowball Earth'? Geologists and climate scientists have been searching for the answer for years but the root cause of the phenomenon remains elusive. Show More Summary

Wyss Institute and Lumos Labs launch research collaboration on memory of high performing individuals

(Lumosity) Researchers at the Wyss Institute for Biologically Inspired Engineering and Harvard Medical School (HMS)'s Personal Genome Project (PGP) announced today a new collaboration with Lumos Labs, makers of brain training program Lumosity. Show More Summary

Portable nanofiber device offers precise, point-and-shoot capability

(Harvard John A. Paulson School of Engineering and Applied Sciences) Harvard researchers have developed a lightweight, portable nanofiber fabrication device that could one day be used to dress wounds on a battlefield or dress shoppers in customizable fabrics.

New pop-up strategy inspired by cuts, not folds

(Harvard John A. Paulson School of Engineering and Applied Sciences) Origami-inspired materials use folds in materials to embed powerful functionality. However, all that folding can be pretty labor intensive. Now, researchers at the Harvard John A. Show More Summary

The ancient art of kirigami is inspiring a new class of materials

Origami-inspired materials use folds in materials to embed powerful functionality. However, all that folding can be pretty labor intensive. Now, researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) are drawing material inspiration from another ancient Japanese paper craft—kirigami.
