Peculiar sounds on Mars

NASA's InSight lander recorded the first-ever Mars-quake in April. Six months later, the lander picked up more "peculiar sounds" on Mars. In October 2019 NASA reported the lander's seismometer was able to pick up subtle noises, including wind noise, as well as more Marsquakes. The quakes had surprisingly high-frequency seismic signals compared to what has been heard since then. Out of more than 100 events detected about 21 are strongly considered to be quakes. The remainder could be quakes as well, but the science team hasn't ruled out other causes. Listen to the sounds of Mars on YouTube

Is Planet 9 a black hole?

The possibility of Plant 9 has fascinated researchers for some time. A new study suggests it may not be a giant planet beyond Neptune — it might be a primordial black hole.

Researchers Jakub Scholtz and James Unwin wrote in the study’s abstract.  "We take these objects to be primordial black holes (PBHs) and point out the orbits of Trans Neptune Objects would be altered if one of these PBHs was captured by the Solar System, in line with the Planet 9 hypothesis."

Primordial black holes are hypothetical black holes that formed soon after the universe. Researchers have not been able to locate them just yet, but they believe they are prevalent and may play a role in the existence of dark matter. Dark matter is believed to account for 85 percent of all matter in the known universe.

Plastic that moves to light

Researchers from Finland's Tampere University were able to train pieces of plastic to walk based on light signals. The plastics are soft actuators that are able to convert energy, in this case, light, into movement.  When illuminated, the plastic bends similar to how humans bend a finger. By illuminating the plastic intermittently,  it walked, albeit slowly, at about the same pace as a snail.
