The bottom-line why folks are investing so much in QC is frankly because it means you will be behind everyone else who has adopted a superior infrastructure. As a consumer, if I can use my private information to secure a loan or access my medical information without fear of exposure of my information as well as performance of my online media and other online services are 100 times faster than any known network service to date; it doesn’t take a brain surgeon to know what I will do,

And, banks, trading houses, etc. know this.

Thanks to the collaborative effort of an international team of scientists led by Professor Winfried Hensinger of the University of Sussex in UK, the world may have gotten one step closer to building the most powerful computer ever — a large-scale quantum computer capable of solving ultra-complex problems that will take a regular computer billions of years to solve.

Quantum computers work quite differently from conventional computers. Instead of typical computer ‘bits’ that can represent either the value ‘0’ or ‘1’, quantum computers use ‘qubits’ (short for quantum bits) that are capable of representing either ‘1’ or ‘0’, or both at the same time. This is made possible by the extraordinary property of qubits known as ‘superpositioning’ — the ability to exist as two different states at the same time.

Superpositioning is what allows quantum computers to effectively handle complex calculations simultaneously. But it is also this particular state that makes quantum computers difficult to build. That’s because an ion in superposition cannot be allowed to come into contact with anything from the outside given the fact that as soon as it does it loses its superposition state, reverting into just one state and consequently removing its ‘quantumness’ and its ability for super-computing.

More mind reading technology and this time they can tell us if the person scanned is thinking about murder.

Brain scans could soon read minds and single out potential criminals before they commit any crimes, researchers claim.

Other uses of functional magnetic resonance imaging could include lie detectors in courtrooms, and anti-terrorist screening.

Scientists say the advancing technology could even be used for so-called neuro-marketing, to determine how much a consumer wanted a product.

Nice.

Summary: Researchers report adult neurogenesis not only helps increase the number of cells in a neural network, it also promotes plasticity in the existing network. Additionally, they have identified the role the Bax gene plays in synaptic pruning.

One goal in neurobiology is to understand how the flow of electrical signals through brain circuits gives rise to perception, action, thought, learning and memories.

Linda Overstreet-Wadiche, Ph.D., and Jacques Wadiche, Ph.D., both associate professors in the University of Alabama at Birmingham Department of Neurobiology, have published their latest contribution in this effort, focused on a part of the brain that helps form memories — the dentate gyrus of the hippocampus.

Scientists on the quest to offer more hope for glioblastoma patients may have found a way to stop the growth of the deadly brain tumor. The discovery targets the genes that sustain the tumor growth past the early stages with the drug mithramycin, which may be more effective than the current chemotherapy treatments.

Glioblastoma is the most common and deadly form of primary brain cancer. In glioblastoma, malignant glial cells form vast networks of tendrils throughout the brain, making it nearly impossible to surgically remove all the cancerous tissues. Dubbed as the “octopus tumor,” the tumor can evade even the most aggressive surgeries, chemotherapies, and radiotherapies, leaving patients with a five-year survival rate of less than 10 percent. Patients are in desperate need of better alternatives or supplementary treatments to beat this notoriously deadly cancer.

In 24 hours, it seems like all the biotech and futurism news is about telepathy. Guess we all read each other’s mind and posted our research and POVs. too funny.

Using quantum materials and technology will mean less invasive implants and no need for head gear in general. Suggest researchers do some due diligence with some of the various research labs and companies experimenting with things like graphene, liquid quantum materials, etc.

“Even though fMRI cannot read minds yet, we need to start deciding how and why we might want to use it, where screening might help, and where it might violate privacy,” Ms Gottwald, a PHD student at St John’s College at the University of Cambridge said. “Because the technology is advancing so rapidly, these kinds of questions are becoming more and more pressing.

“The aim of the book is to give readers the basics about an exciting and emerging field.

“When the public read about fMRI in the media, they get basic facts, but often out of context.

Brain resets during sleep; guess why I need my 5 shot espressos in the morning.

Summary: Researchers examine if the size of synapses alters during sleep and wake states.

Source: University of Wisconsin Madison.

Striking electron microscope pictures from inside the brains of mice suggest what happens in our own brain every day: Our synapses – the junctions between nerve cells – grow strong and large during the stimulation of daytime, then shrink by nearly 20 percent while we sleep, creating room for more growth and learning the next day.

The four-year research project published today in Science offers a direct visual proof of the “synaptic homeostasis hypothesis” (SHY) proposed by Drs. Chiara Cirelli and Giulio Tononi of the Wisconsin Center for Sleep and Consciousness.

Way cool.

Feb. 2 (UPI) — Scientists at the University of California, Santa Barbara want to study the effects of various mechanical forces on individual brain cells. Until now, however, researchers didn’t have the right tools.

To study brain impacts at the nanoscale, researchers built the world’s tiniest hammer — the μHammer, or “microHammer.” The μHammer is a cellular-scale machine capable of applying a variety of mechanical forces to neural progenitor cells, brain-centric stem cells. Eventually, scientists hope to use the hammer to apply forces to neurons and neural tissue.

The hammer piggybacks on existing cell-sorting technology which isolates individual cells for diagnostics and immunotherapy. Once isolated, the machine can apply a range of forces. Post-impact structural and biomechanical analysis will allow scientists study the effects of focus in near real-time.
