The feat, done with magnetic fields, could lead to better understanding of zero-g bone loss.

The frightening future implications of new report from researchers at the Weizmann Institute of Science in Israel caused a stir among observers of the international science community.

Using neither sperm nor egg, researchers created the world’s first synthetic mouse embryo and watched it grow for over eight days inside of a specially designed bioreactor that served as a womb, according to Live Science Magazine.

The article describes what occurs inside the artificial womb. “Within the device, embryos float in small beakers of nutrient-filled solution, and the beakers are all locked into a spinning cylinder that keeps them in constant motion. This movement simulates how blood and nutrients flow to the placenta. The device also replicates the atmospheric pressure of a mouse uterus.”

Low-tech approach can quintuple yield and slash need for soil pesticide.

Humboldt squid can communicate complex messages. Let’s hope that they don’t evolve lungs and legs, or humanity might be in real trouble.

The generation of membrane curvature is essential for the formation of membrane tubules, sheets and vesicles, and hence, underlies membrane trafficking events. Various protein-based mechanisms function in membrane bending, and these appear to be organized in time and space by protein coats, including clathrin, caveolar coat complex, and COPI and COPII coats.

A trio of researchers, two with Princeton University, the other the Max Planck Institute for Biological Cybernetics, has developed a reinforcement learning–based simulation that shows the human desire always to want more may have evolved as a way to speed up learning. In their paper posted in the open-access PLOS Computational Biology, Rachit Dubey, Thomas Griffiths and Peter Dayan describe the factors that went into their simulations.

Researchers studying human behavior have often been puzzled by people’s seemingly contradictory desires. Many people have an unceasing desire for more of certain things, even though they know that meeting those desires may not result in the desired outcome. Many people want more and more money, for example, with the idea that more money would make life easier, which should make them happier. But a host of studies has shown that making more money rarely makes people happier (with the exception of those starting from a very low income level). In this new effort, the researchers sought to better understand why people would have evolved this way. To that end, they built a simulation to mimic the way humans respond emotionally to stimuli, such as achieving goals. And to better understand why people might feel the way they do, they added checkpoints that could be used as a happiness barometer.

The simulation was based on reinforcement learning, in which people (or a machine) continue doing things that offer a positive reward and cease doing things that offer no reward or a negative reward. The researchers also added simulated emotional reactions to the known negative impacts of habituation and comparison, whereby people become less happy over time as they get used to something new and become less happy when seeing that someone else has more of something they want.
