Satellite uses giant net to practice capturing space junk

A British satellite, designed to test out ways to clean up debris in space, just successfully ensnared a simulated piece of junk in orbit using a big net. On Sunday, September 16th, the vehicle, known as the RemoveDEBRIS satellite, deployed its onboard net, which then captured a nearby target probe that the vehicle had released a few seconds earlier. The demonstration shows that a simple idea like a net may be an effective way to clean up all the material orbiting Earth.

The RemoveDEBRIS satellite is meant to try out numerous different methods for cleaning up space junk, which has become a growing problem ever since we started launching rockets into orbit. Thousands of dead, uncontrollable objects linger in orbit, including defunct…

3D-printed gun maker Cody Wilson charged with sexually assaulting underage girl

Defense Distributed founder Cody Wilson — known for his fight with the US government over 3D-printed guns — has been charged with sexually assaulting a minor, according to The Austin American-Statesman. The Statesman reports that police filed an arrest warrant for Wilson today in Travis County, Texas, alleging that a girl under 17 years old (the state’s age of consent) said Wilson paid her for sex after meeting on a site called SugarDaddyMeet.com. The Statesman reports that jail records show Wilson had not been booked as of this morning, but police had corroborated the story with hotel records and surveillance footage. Wilson did not immediately respond to a phone call requesting comment.

According to the Statesman, Wilson began…

Mineral weathering from thawing permafrost can release substantial CO2

The amount of carbon dioxide released from thawing permafrost might be greater than previously thought, according to a new study by ecologists. The research is the first to document the potential for substantial contributions of CO2 from thawing permafrost to the atmosphere through an inorganic process called mineral weathering.

New insight into aging

Researchers examined the effects of aging on neuroplasticity in the primary auditory cortex, the part of the brain that processes auditory information. Neuroplasticity refers to the brain’s ability to modify its connections and function in response to environmental demands, an important process in learning.
