Tapping into the brain’s star power No longer just ‘brain glue’, astrocytes are coming to the fore
Astrocytes have a distinctive 3D branching shape.Credit: National Center for Microscopy and Imaging Research, UCSD.In the mid-1850s, German anatomist Rudolf Virchow and others examining brains under the microscope noticed mysterious structures filling the space around and between the neurons that held their interest. Virchow dubbed these structures nervenkitt, literally ‘nerve-glue’, and translated as ‘neuroglia’...
Basic quantum computation achieved with silicon for first time
(Image: Mehau Kulyk/SPL) The ingredients for superfast computers could be nearly in place. For the first time, researchers have demonstrated that two silicon transistors acting as quantum bits can perform a tiny calculation. Now it’s just a question of using these as the building blocks of a larger quantum computer – taking advantage of the very material that is ubiquitous in conventional electronics.

This is What Happens When Deep Learning Neural Networks Hallucinate
A Reverse Hallucination Technique So the researchers decided to reverse the process, to “turn it upside down” in order to better visualize the network’s inner workings. By giving it free reign and asking it to interpret and “enhance an input image in such a way as to elicit a particular interpretation,” they were hoping to get more insight into what trained features the networks understood and what they did not.

How humans evolved supersize brains.
When it comes to brains, size isn’t everything. The human brain is much smaller than that of an elephant or whale. But there are far more neurons in a human’s cerebral cortex than in the cortex of any other animal.
Brains May Teeter Near Their Tipping Point.
