Musk’s Dragons stand ready to help.
Russian rockets are essential for keeping the station in place — but a modified Crew Dragon could do the trick.
Combining two cutting-edge techniques reveals that neurons in the prefrontal cortex are built to respond to reward or aversion, a finding with implications for treating mental illness and addictions.
The prefrontal cortex plays a mysterious yet central role in the mammalian brain. It has been linked to mood regulation, and different cells in the prefrontal cortex seem to respond to positive and negative experiences. How the prefrontal cortex governs these opposing processes of reward or aversion, however, has been largely unknown.
In a new paper published online May 26 in Cell, researchers at Stanford, led by Karl Deisseroth, have united two transformational research techniques to show how the prefrontal circuits that process positive and negative experiences are distinctly and fundamentally different from one another, both in how they function and in how they are wired to other parts of the brain.
Is Metaverse a boom or a bubble?
There is hardly a day that goes by without a mention of the metaverse. Since Facebook’s brand name changed to Meta, the word has really caught on and everybody wants to be a part of it.
Mark Zuckerberg may have drawn the world’s attention to the metaverse but the digital world has been on the rise for quite some time. Minecraft, an online game, has been around since 2011, where not only does one get to stay in a digital world but also has the tools to build it around themselves. With their versions of the metaverse, what Meta and the others now want to do, is build up these worlds rapidly, so that people can just come and spend their time in there. ## Time is Money.

A new proof significantly strengthens a decades-old result about the ubiquity of ways to represent whole numbers as sums of unit fractions.
Scientists in China have created a transistor using graphene and molybdenum disulfide with a gate length of just 0.34 nanometers. “We have realized the world’s smallest gate-length transistor,” says one of the paper’s authors, an electrical engineer at Tsinghua University in Beijing.
