Scientists use hydrophone to listen in on methane seeps in ocean
A research team has successfully recorded the sound of methane bubbles from the seafloor off the Oregon coast, opening the door to using acoustics to identify -- and perhaps quantify -- this important greenhouse gas in the ocean.

Personalized 'deep learning' equips robots for autism therapy
Researchers have now developed a type of personalized machine learning that helps robots estimate the engagement and interest of each child during these interactions, using data that are unique to that child. Armed with this personalized 'deep learning' network, the robots' perception of the children's responses agreed with assessments by human experts, with a correlation score of 60 percent.

Scientists find evidence of complex organic molecules from Enceladus
Using mass spectrometry data from NASA's Cassini spacecraft, scientists found that large, carbon-rich organic molecules are ejected from cracks in the icy surface of Saturn's moon Enceladus. Scientists think chemical reactions between the moon's rocky core and warm water from its subsurface ocean are linked to these complex molecules.

Why bacteria survive in space
Earth germs could be contaminating other planets. Despite extreme decontamination efforts, bacteria from Earth still manages to find its way into outer space aboard spacecraft. Biologist are working to better understand how and why some spores elude decontamination.

`Oumuamua gets a boost
`Oumuamua, the first interstellar object discovered in the Solar System, is moving away from the Sun faster than expected. This anomalous behavior was detected by a worldwide astronomical collaboration. The new results suggest that `Oumuamua is most likely an interstellar comet and not an asteroid.

Study yields a new scale of earthquake understanding
Nanoscale knowledge of the relationships between water, friction and mineral chemistry could lead to a better understanding of earthquake dynamics, researchers said in a new study. Engineers used microscopic friction measurements to confirm that, under the right conditions, some rocks can dissolve and may cause faults to slip.

Recreating the chameleon: Material mimics color changes of living organisms
Researchers created a material containing photochromic dyes, crystals providing structural coloration, and a colored background that mimics the color changes that animals such as frogs, chameleons, and octopuses can display. This material could display different patterns and images depending on whether it was exposed to visible or ultraviolet light, or had a white or black background, which suggests its potential application in a range of next-generation display technologies.
