High levels of labile iron have been linked to neurodegenerative disorders like Alzheimer’s before. Similarly, copper is another mineral typically shielded safely in a protein, yet thoroughly capable of making a mess of our brains in labile form.

Set aside every scrap of iron inside a human body and you might have enough to fashion a nail or two. As for copper, you’d be lucky to extract just enough to make a small earring.

Scarce as they are, these two metals are necessary for our survival, playing essential roles in human growth and metabolism. But one place we wouldn’t expect to find either is clumped inside our brain cells.

Last Tuesday, teams from Google and Harvard published an intricate map of every cell and connection in a cubic millimeter of the human brain.

The mapped region encompasses the various layers and cell types of the cerebral cortex, a region of brain tissue associated with higher-level cognition, such as thinking, planning, and language. According to Google, it’s the largest brain map at this level of detail to date, and it’s freely available to scientists (and the rest of us) online. (Really. Go here. Take a stroll.)

“The human brain is an immensely complex network of brain cells which is responsible for all human behavior, but until now, we haven’t been able to completely map these connections within even a small region of the brain,” said Dr. Alexander Shapson-Coe, a postdoctoral fellow at Harvard’s Lichtman Lab and lead author of a preprint paper about the work.

A team of scientists at the University of Sussex have for the first time built a modular quantum brain scanner, and used it to record a brain signal. This is the first time a brain signal has been detected using a modular quantum brain sensor anywhere in the world. It’s a major milestone for all researchers working on quantum brain imaging technology because modular sensors can be scaled up, like Lego bricks. The team have also connected two sensors like Lego bricks, proving that whole-brain scanning using this method is within reach—as detailed in their paper, which is published today in pre-print. This has not been possible with the currently commercially available quantum brain sensors from the United States.

These modular devices work like play bricks in that they can be connected together. This opens up the potential for whole–brain scanning using quantum technology, and potential advances for neurodegenerative diseases like Alzheimer’s.

The device, which was built at the Quantum Systems and Devices laboratory at the university, uses ultra-sensitive quantum sensors to pick up these tiniest of magnetic fields to see inside the brain in order to map the neural activity.

Google has helped create the most detailed map yet of the connections within the human brain. It reveals a staggering amount of detail, including patterns of connections between neurons, as well as what may be a new kind of neuron.

The brain map, which is freely available online, includes 50000 cells, all rendered in three dimensions. They are joined together by hundreds of millions of spidery tendrils, forming 130 million connections called synapses. The data set measures 1.4 petabytes, roughly 700 times the storage capacity of an average modern computer.

The data set is so large that the researchers haven’t studied it in detail, says Viren Jain at Google Research in Mountain View, California. He compares it to the human genome, which is still being explored 20 years after the first drafts were published.

Summary: Higher sugar diets during childhood increase the risk for obesity, cognitive impairments, and attention deficits as adults, a new study reports.

Children who consume too much sugar could be at greater risk of becoming obese, hyperactive, and cognitively impaired, as adults, according to the results of a new study of mice led by QUT and published by Frontiers in Neuroscience.

Manipulative individuals who endorse the belief that “the ends justify the means” are more likely to endorse technology that allows a person to upload their human consciousness into a machine, according to new research published in Personality and Individual Differences. The study indicates that there is a strong link between the personality trait known as Machiavellianism and acceptance of mind uploading.

The new findings shed light on how psychological dispositions are related to approval of futuristic technology.

“Through-out my adult life I have been hanging out with individuals who self-identify as transhumanists. These people are interesting, since their values and orientation towards the daily life are so different from others,” explained study author Michael Laakasuo, an adjunct professor of cognitive science at the University of Helsinki and principal investigator of the Moralities of Intelligent Machines research group.
