PS5 owners lose access to hundreds of games as digital purchases wiped from their accounts
Posted by Raphael Ramos in categories: entertainment, futurism
Problems with the future of gaming.
A strange bug is removing people’s games on PlayStation 4 and 5, and Vita, and Sony doesn’t have a fix.
It wasn’t long ago that PlayStation sparked fan outrage when it said it would remove Discovery video content from people’s libraries, even though they had paid for it.

Biomolecular Bonsai: Controlling the Pruning and Strengthening of Neuron Branches in the Brain
Posted by Dan Breeden in categories: biotech/medical, neuroscience
Researchers identify molecular cues that make developing neurons remodel their connections.
At this very moment, the billions of neurons in your brain are using their trillions of connections to enable you to read and comprehend this sentence.
Now, by studying the neurons involved in the sense of smell, researchers from Kyushu University’s Faculty of Medical Sciences report a new mechanism behind the biomolecular bonsai that selectively strengthens these connections.

Synaptic Transmission: Not a One-Way Street for Key Brain Synapse in the Hippocampus
Posted by Dan Breeden in categories: chemistry, neuroscience
Key synapse acts as a “smart teacher,” sending messages against the usual flow of information in the brain.
Information flows in a well-defined direction in the brain: Chemical and electrical signals are passed from one neuron to the other across the synapse, from the pre-synaptic to the post-synaptic neuron. Now, Peter Jonas and his group at the Institute of Science and Technology Austria (IST Austria) show that information also travels in the opposite direction at a key synapse in the hippocampus, the brain region responsible for learning and memory.
At the so-called mossy fiber synapse, the post-synaptic CA3 neuron influences how the pre-synaptic neuron, the so-called mossy fiber neuron, fires. “We have shown, for the first time, that a retrograde information flow is physiologically relevant for pre-synaptic plasticity,” says Yuji Okamoto, a postdoc in the group of Peter Jonas at IST Austria and co-first author of the paper published in Nature Communications.

To observe photoswitches, stick on a platinum atom
Posted by Dan Breeden in categories: biotech/medical, computing, mobile phones
Advances with photoswitches could lead to a smartphone that’s soft and flexible and shaped like a hand so you can wear it as a glove, for example. Or a paper-thin computer screen that you can roll up like a window shade when you’re done using it. Or a TV as thin as wallpaper that you can paste on a wall and hardly know it’s there when you’re not watching it.
Photoswitches, which turn on and off in response to light, can be stitched together to replace the transistors used in electronic devices that control the flow of the electric current.
Commercial silicon transistors are brittle, nontransparent, and typically several microns thick, about the same thickness as a red blood cell. In contrast, photoswitches are one or two nanometers, about 1,000 times thinner. They can also be mounted on graphene, a transparent, flexible material.
