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.
