In the distant reaches of the universe, almost 13 billion light-years from Earth, a strange species of galaxy lay hidden. Cloaked in dust and dimmed by the intervening distance, even the Hubble Space Telescope couldn't spy it. It took the revealing power of NASA's Spitzer Space Telescope to uncover not one, but four remarkably red galaxies.

Harvard researchers have developed a “primer” to identify some of the most useful probes for super-resolution imaging. As described recently on Nature Methods’ website, the work also identified the key characteristics that are important for imaging, giving researchers a framework for evaluating other probes, or even designing custom-made molecules to use in imaging.
A group of researchers is working to map how the brain is wired in an effort to pinpoint the causes of — and potential treatments for — schizophrenia, autism, and a host of other disorders.
By nestling quantum dots in an insulating egg-crate structure, researchers at the Harvard School of Engineering and Applied Sciences have demonstrated a robust new architecture for quantum-dot light-emitting devices (QD-LEDs).
The Harvard College Observatory built its foundation in the mid-1800s, after an epidemic of train wrecks prompted the railroads to seek a regional standard for greater accuracy and safety.

Harvard Business School and MIT Sloan students put IBM’s groundbreaking, “Jeopardy!”-winning computer to the test in a live match-up on Oct. 31. But outsmarting Watson, it turns out, is a not-so-elementary task.
Harvard School of Engineering and Applied Sciences’ PlateMate project proves that a well-managed crowd can play the role of a trained nutritionist.
Though it won’t be completed until 2013, the Atacama Large Millimeter/submillimeter Array, a radio telescope observatory under construction in northern Chile, is already the most powerful and complex such facility ever built, and four astronomers from the Harvard-Smithsonian Center for Astrophysics are among those first in line to use it.
Two fellows at Harvard’s Berkman Center for Internet & Society revolutionized how people create and consume digital information.
Harvard-Smithsonian Center for Astrophysics researcher Justin Kasper has designed an instrument that will peek out from behind a heat shield to touch the sun’s atmosphere on a NASA solar probe designed to get far closer to the sun than any before.
Prescription data stripped of identify information seems not so anonymous after all. Researcher Latanya Sweeney aims to make such personal data more secure and to provide recourse for people who are harmed by privacy breaches.
Scientists from around the world gathered at the Radcliffe Institute for Advanced Study Oct. 14 for a symposium on advancing efforts to study and design molecules as motors.
Engineers and physicists at Harvard have managed to capture light in tiny diamond pillars embedded in silver, releasing a stream of single photons at a controllable rate.
All three winners of the 2011 Nobel Prize in physics have connections to Harvard — including two whose Ph.D.s launched them into their winning notion of an accelerating universe and the puzzle of dark matter.
Harvard School of Engineering and Applied Sciences have developed a new device that creates strong forces more efficiently than traditional optical tweezers and eliminates a problem that caused earlier setups to overheat.
Adopting the pitcher plant’s slick strategy, a group of applied scientists at Harvard have created a material that repels just about any type of liquid, including blood and oil, and does so even under harsh conditions like high pressure and freezing temperatures.
