A new satellite system sucks in air to provide unlimited propulsion (3 minute read)

Barcelona-based startup Kreios Space plans to send satellites on very low Earth orbit (VLEO) missions. VLEO is a zone between 95 to 250 miles of altitude. Most satellites operate at a higher altitude, where they can maintain a geostationary orbit with minimal thrust. Satellites in VLEO need to generate constant thrust in order to not deorbit. Kreios Space plans to use a system that creates thrust by absorbing air and using it to generate plasma. Satellites in VLEO do not leave space debris as they deorbit and disintegrate into the atmosphere. A video from Kreios showing how the propulsion system works is available in the article.

Scientists Watch a Memory Form in a Living Brain (6 minute read)

Scientists from the University of Southern California were able to visualize memories forming in the brains of genetically modified zebrafish in the lab. The team expected the brains to form new neurons after learning a fear response but instead found that synapses were pruned from an area related to associative memories. It is possible that fish brains use different methods to encode different types of memories. They may choose to prune synapses to form stronger responses when presented with fear-stimuli. The researchers hope to see if their findings will translate to other animals.

Samsung caught throttling 10,000 phone apps—and its own home screen (2 minute read)

Samsung has been accused of throttling 10,000 Android apps. It uses an app called the Game Optimizing Service to throttle non-benchmark apps, dropping performance by up to 45%. The behavior has been observed on the Galaxy S10, S20, S21, and S22. Users have been able to produce wild performance changes by changing app package names. The throttling applies to many apps, not just games. It even applies to Samsung's own apps and home screen.

What Chimpanzees Know About Giving Medicine (3 minute read)

The chimpanzees of the Rekambo community in Gabon, West Africa, have been observed applying insects to their open wounds and the wounds of other community members. No other animal, apart from humans, has ever been seen treating the wounds of others. Self-medication with plant material is common, but the use of insects to treat wounds is unique. It is unknown which insects were used, or whether the treatment is effective. The behavior may be evidence that chimpanzees can display prosocial behaviors.
