Simple logic for nanofluidic computing simulated
Invigorating the idea of computers based on fluids instead of silicon, researchers have shown how computational logic operations could be performed in a liquid medium by simulating the trapping of ions (charged atoms) in graphene (a sheet of carbon atoms) floating in saline solution. The scheme might also be used in applications such as water filtration, energy storage or sensor technology.

Computing power used to track the spread of cancer
Researchers have developed a new computational method that increases the ability to track the spread of cancer cells from one part of the body to another. This migration of cells can lead to metastatic disease, which causes about 90 percent of cancer deaths from solid tumors -- masses of cells that grow in organs such as the breast, prostate or colon. Understanding the drivers of metastasis could lead to new treatments aimed at blocking the process of cancer spreading through the body.

Using artificial intelligence to understand volcanic eruptions from tiny ash
Scientists have shown that an artificial intelligence program called a Convolutional Neural Network can be trained to categorize volcanic ash particle shapes. Because the shapes of volcanic particles are linked to the type of volcanic eruption, this categorization can help provide information on eruptions and aid volcanic hazard mitigation efforts.

Path to zero emissions starts out easy, but gets steep
Carbon dioxide emissions from human activities must approach zero within several decades to avoid risking grave damage from the effects of climate change. This will require creativity and innovation, because some types of industrial sources of atmospheric carbon lack affordable emissions-free substitutes, according to a new article.

Atomic movie of melting gold could help design materials for future fusion reactors
Researchers have recorded the most detailed atomic movie of gold melting after being blasted by laser light. The insights they gained into how metals liquefy have potential to aid the development of fusion power reactors, steel processing plants, spacecraft and other applications where materials have to withstand extreme conditions for long periods of time.

Injectable electronics offer powerful new tool in understanding how retinal cells work
For decades, scientists hoping to understand how the retina interprets visual input have often had to resort to invasive techniques to dissect the retina from the animal in an effort to record the cells' activity, but a new system could make it possible to track the firing patterns of dozens of cells chronically in awake animals.

Mars valleys traced back to precipitation
The valley networks of Mars bear a strong resemblance to those found in arid landscapes on Earth. Researchers have been able to demonstrate this using the branching angles of river valley confluences. Based on these observations, they infer that Mars once had a primeval climate in which sporadic heavy precipitation eroded valleys.

More clues that Earth-like exoplanets are indeed Earth-like
Researchers suggest that two Earth-like exoplanets (Kepler-186f and 62f) have very stable axial tilts, much like the Earth, making it likely that each has regular seasons and a stable climate.
