New computer code for mechanics of tissues and cells in three dimensions      (via sciencedaily.com)     Original source 

Biological materials are made of individual components, including tiny motors that convert fuel into motion. This creates patterns of movement, and the material shapes itself with coherent flows by constant consumption of energy. Such continuously driven materials are called 'active matter'. The mechanics of cells and tissues can be described by active matter theory, a scientific framework to understand shape, flows, and form of living materials. The active matter theory consists of many challenging mathematical equations. Scientists have now developed an algorithm, implemented in an open-source supercomputer code, that can for the first time solve the equations of active matter theory in realistic scenarios. These solutions bring us a big step closer to solving the century-old riddle of how cells and tissues attain their shape and to designing artificial biological machines.

Scientists have solved the damselfly color mystery      (via sciencedaily.com)     Original source 

For over 20 years, a research team has studied the common bluetail damselfly. Females occur in three different color forms -- one with a male-like appearance, something that protects them from mating harassment. In a new study, an international research team found that this genetic color variation that is shared between several species arose through changes in a specific genomic region at least five million years ago.

Much more than waste: Tiny vesicles exchange genetic information between cells in the sea      (via sciencedaily.com)     Original source 

Researchers take a look at data that has so far been mostly discarded as contamination, revealing the previously underestimated role of extracellular vesicles (EVs). These are important for the exchange of genetic information between cells and thus for the microbial community in the sea.

The mind's eye of a neural network system      (via sciencedaily.com)     Original source 

A new tool, based on topology, makes finding the areas where neural networks are confused as simple as spotting mountaintops from an airplane. The ability to spot and address those areas of confusion should enable more confident application of neural networks in high-stakes decision scenarios or image prediction tasks like healthcare and research.

Realistic talking faces created from only an audio clip and a person's photo      (via sciencedaily.com)     Original source 

A team of researchers has developed a computer program that creates realistic videos that reflect the facial expressions and head movements of the person speaking, only requiring an audio clip and a face photo.   DIverse yet Realistic Facial Animations, or DIRFA, is an artificial intelligence-based program that takes audio and a photo and produces a 3D video showing the person demonstrating realistic and consistent facial animations synchronised with the spoken audio (see videos).

Use it or lose it: New robotic system assesses mobility after stroke      (via sciencedaily.com)     Original source 

Stroke is a leading cause of long-term disability worldwide. Each year more than 15 million people worldwide have strokes, and three-quarters of stroke survivors will experience impairment, weakness and paralysis in their arms and hands. Many stroke survivors rely on their stronger arm to complete daily tasks, from carrying groceries to combing their hair, even when the weaker arm has the potential to improve.

Multiple evolutionary trajectories in aquatic crocodiles      (via sciencedaily.com)     Original source 

In the geological past, several groups of crocodiles evolved towards a morphology adapted to marine life. However, the extent of these adaptations and their evolutionary trajectories remained unknown. An exhaustive study of their morphology has now shed light on the evolutionary mechanisms at work, thanks to three-dimensional reconstructions.
