Exciton limits are meant to be broken: OLED surpasses 100 percent exciton production efficiency
Researchers have demonstrated an OLED that uses singlet fission to boost the percentage of excitons created per pair of electrical charges to over 100 percent. This increase of light-producing excitons when one singlet exciton is split into two triplet excitons through singlet fission results in a stronger emission intensity and is promising for the development of high-intensity near-infrared OLEDs for biological and communications applications.

New software designed for rapid, automated identification of dendritic spines
Researchers have released open source software, connecting and building the neuroscience coding community. The software has the potential to dramatically increase experiment workflow, shaving off hours of imaging time. Weaving in an element of machine learning, the algorithm can be taught how to differentiate between dendrite backbone and dendritic spines after being fed a training data set of previously identified spines.

Heat-conducting crystals could help computer chips keep their cool
As consumers demand smaller, faster and more powerful electronic devices that draw more current and generate more heat, the issue of heat management is reaching a bottleneck. Researchers have created a potential solution -- boron arsenide crystals with high thermal conductivity, which might be used in future electronics to help keep devices from overheating.

Ultra-high-speed 'electron camera' catches molecules at a crossroads
An extremely fast 'electron camera' has produced the most detailed atomic movie of the decisive point where molecules hit by light can either stay intact or break apart. The results could lead to a better understanding of how molecules respond to light in processes that are crucial for life, like photosynthesis and vision, or that are potentially harmful, such as DNA damage from ultraviolet light.

'Blind' Cheetah 3 robot can climb stairs littered with obstacles
MIT's Cheetah 3 robot can now leap and gallop across rough terrain, climb a staircase littered with debris, and quickly recover its balance when suddenly yanked or shoved, all while essentially blind. The 90-pound mechanical beast -- about the size of a full-grown Labrador -- is intentionally designed to do all this without relying on cameras or any external environmental sensors.
