Harvard researchers have discovered that the study contains several statistical and methodological mistakes, and that when these are corrected, the study actually shows that the replication rate in psychology is quite high.

A new study suggests that many of the cognitive capacities that humans use for cooking — a preference for cooked food, the ability to understand the transformation of raw food into cooked, and even the ability to save and transport food to cook it — are shared with chimpanzees.
A team of scientists has engineered a form of the genome-editing protein Cas9 that can be controlled by a small molecule and offers improved DNA specificity.
A new study has found that the financial health of Social Security, the program millions of Americans have relied on for decades as a crucial part of their income, has been dramatically overstated.
Claudine Gay, a Harvard professor of government and African and African American Studies, and a distinguished scholar of mass political behavior, has been appointed dean of social science in the Faculty of Arts and Sciences.
Roland Fryer, Harvard’s Henry Lee Professor of Economics, has been awarded the American Economic Association’s John Bates Clark Medal, which is given annually to a rising young economist.
A new study shows that birds use two highly stereotyped postures to avoid obstacles in flight. The study could open the door to new ways to program drones and other unmanned aerial vehicles to avoid similar obstacles.
Using an electro-chemical process to etch materials, Harvard scientists have developed a system of patterning that works in just minutes, as opposed to the weeks needed for other techniques. Researchers can build photonic structures that control the light hitting the device and greatly increase its efficiency.
Harvard researchers were able to predict when test flames in the lab were likely to switch from slow- to fast-moving fires, which could open the way to making similar predictions for forest fires.
Harvard researchers have solved the mystery of how some bacteria move across surfaces with the discovery of a rotary motor in the bacterium Flavobacterium johnsoniae.
A new study finds no connection between hip width and efficient locomotion, and suggests that scientists have long approached the problem in the wrong way.
A new study examines how different kinds of shared beliefs can affect how people cooperate, and how people use common knowledge, a type of shared understanding, to coordinate their actions.
Sixty-three Faculty of Arts and Sciences (FAS) employees from 36 departments — representing 2.5 percent of the FAS staff — were recognized at the sixth annual awards ceremony and reception, held in the faculty room of University Hall.
