Though variability is often portrayed as a flaw to be overcome, Harvard researchers now say that, in motor function, it is a key feature of the nervous system that helps promote better or more successful ways to perform a particular action.
Harvard scientists say they’re closer to unraveling one of the most basic questions in neuroscience — how the brain encodes likes and dislikes — with the discovery of the first receptors in any species evolved to detect cadaverine and putrescine, two of the chemical byproducts responsible for the distinctive — and to most creatures repulsive — smell of rotting flesh.

Harvard is the leading producer of Fulbright Scholars for 2013–14, with 44 students — 32 from Harvard College and 12 from the Graduate School of Arts and Sciences — receiving the prestigious grants to conduct research or teach abroad. Of the 44, 39 accepted the awards.
Harvard researchers have solved the nearly 200-year-old mystery of how Rafflesia, the largest flowering plants in the world, develop.

Nine professors in Harvard’s Faculty of Arts and Sciences have been named Walter Channing Cabot Fellows. The 2013 honorees were awarded for their distinguished publications.
New research suggests that, despite moonlight’s apparent hunting advantage, large predators such as lions are actually less active on the brightest nights, while many prey animals — despite the risk of being eaten — become more active.
A new study found that middle school teachers can have a real impact not only on students’ short-term educations, but on whether they attend college and on the size of their future paychecks.
Using scans of the brain, Harvard researchers show that patterns of neural activity change when people look at black and white faces, and male and female faces.
Following the announcement of the 2013 Nobel Prize in physics, Harvard faculty who participated in the search for the Higgs boson said they were honored to have played a role in the discovery of the particle that proved theoretical predictions correct.

Working with colleagues at the Harvard-MIT Center for Ultracold Atoms, Professor of Physics Mikhail Lukin and post-doctoral fellow Ofer Firstenberg have managed to coax photons into binding together to form molecules — a state of matter that, until recently, had been purely theoretical.
Harvard researchers have found that the brain uses two largely independent neural circuits to learn spatial and temporal aspects of complex motor skills.
Jazz musician and composer Vijay Iyer, who won a MacArthur Foundation grant, in January will become the first Franklin D. and Florence Rosenblatt Professor of the Arts in Harvard’s Department of Music.
Harvard researchers recently developed the most detailed “specificity profile” for Cas9 — a “machine” made of protein and RNA that can be programmed to target specific DNA sequences and to precisely cut, paste, and turn on or turn off genes.
