Originally scheduled to operate on the Red Planet’s surface for 90 Martian days, the rover Opportunity has now logged more than 3,500 days, traveled nearly 39 kilometers, and collected a trove of data that scientists have used to study the planet’s early history, particularly any past traces of water.
Scientists at Harvard have identified a previously unknown embryonic signal, dubbed Toddler, that instructs cells to move and reorganize themselves, through a process known as gastrulation, into three layers.
January@GSAS offered more than 100 classes, seminars, and training sessions to students in Harvard’s Graduate School of Arts and Sciences during semester break. Students had the chance to escape the lab or library, and spend time exploring subjects that might not otherwise appear in a Harvard course catalog.
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.
In making the most precise measurements ever of the shape of electrons, Harvard and Yale scientists have raised serious doubts about several popular theories of what lies beyond the Higgs boson.
A new Harvard study shows that, in as little as a day, diet can alter the population of microbes in the gut – particularly those that tolerate bile - as well as the types of genes expressed by gut bacteria.
